hello, my sister has a homework that said Find the ip of 5 ISP what that means? the ip of Comcast, AT&T, etc. or the 5 whatever serves ip

Journeyman Geek

The question is horribly written ;p

Emilio Gort

sorry is in spanish

Averigua la dirección IP de 5 proveedores de Internet.

but in spanish is horrible too

Journeyman Geek

makes even less sense to me

serverfault.com/questions/151122/… MAY be a start

assuming they mean what they think you mean

Michael Frank

@JourneymanGeek I have MIKE-PC, SERVERBOX, HTPC, and GAMING

Journeyman Geek

@MichaelFrank: that wouldn't work for me.

It would be like "Geek-laptop Geek-desktop Geek-mini-itx-server Geek-brix-celery"

@EmilioGort muchas veces he visto catedraticos que preguntan muy vagamente en vez de enseñando correctamente :( esa técnica sirve a separar los estudiantes: ellos que advinan correctamente, y ellos que adivinan incorrectamente. es muy perezoso :(

Emilio Gort

@allquixotic si asi mismo es, a mi me dio dolor de cabeza esa pregunta

if you want I can show you the question list

1-1) Resuma brevemente, por qué se argumenta que la guerra fría fue un factor determinante para el origen de Internet.

2) Resuma brevemente el origen de ARPA, cuantos nombres tuvo, su principal aporte y cuando desapareció definitivamente.

3) Que es el código ASCII y cuál es la importancia?

5) ¿Por qué cree que son tan importantes los servidores DNS?

6) Averigua la dirección IP de 5 proveedores de Internet

7) Investigue y enumere qué ventajas y desventajas existen entre los siguientes tipos de cableado:

8) Mencione algunas ventajas, riesgos y ejemplos de cortafuegos (Firewall).
9) Enumere algunas ventajas y desventajas de las siguientes topologías de red:
• Bus

allquixotic

@JourneymanGeek unfortunately, much of the IT-related curriculum in the United States is very outdated, and there's little motivation to update

not sure why a biomedical engineer has to know about star and ring topologies, since those are totally obsolete

"I can totally use this knowledge about how the Cold War was an important driver for the creation of the Internet to help create new probiotic yogurt cultures!"

Journeyman Geek

lol

@allquixotic: When I was doing EE, they made us do an introduction to life sciences cource.

but the question about the cold war was interested to me

I didn't know that

@JourneymanGeek necessity is the mother of invention

Journeyman Geek

ooh

interesting comments, saying my understanding of it was wrong ;p

allquixotic

now all we need is a war that necessitates the creation of batteries with 50 times better energy density, lower cost and lifespan than current tech, and we'll be set

Emilio Gort

the question was closed anyway

nukes+solar+wind make electricity -> 10 pound battery the size of a large laptop in the middle of the car gives you 500 miles of range and lasts for longer than the car's frame can withstand the environment before rusting out

@allquixotic: outside of the actual fighting, the cold war was an awesome driver of technology

@allquixotic: less so

@allquixotic: :/

well, the current civilisation is sinking back to bread and circuses.

allquixotic

we've never had a worldwide civilization fall before, though, and we aren't quite sure what will happen if it does

if a civilization that accounts for half of the humans in the world -- or fewer -- experiences a dramatic fall, eh, we move on and they become history

if a civilization that accounts for 98% of the humans in the world falls, that could be bad

@JourneymanGeek don't ask "what OS" -- he'll just say "Windows"... you have to say and version

Journeyman Geek

@allquixotic: true!

allquixotic

people like this don't know squat about computers and expect anything that looks like a computer to continue to work for everything, forever

rofl

@allquixotic: my spare case is an actual beige box

and my answer to that would be "sure. Let me just upgrade everything"

allquixotic

2:27 AM

hey, a full ATX-compatible beige box from the 90s should theoretically still be good for building out a modern PC. cooling WILL be an issue though

Journeyman Geek

@allquixotic: actually no

allquixotic

also, card depth for things like TITANs and 7970s

Journeyman Geek

PIVs ran hotter than anything modern

that case even has the little chimney vent

allquixotic

@JourneymanGeek but modern system boards and GPUs put out far more heat than a PIV

PIV TDP never sniffed 250W, yet that number isn't unheard of for high-end GPUs

Journeyman Geek

@allquixotic: I could stuff a pair of side fans into it ;p

allquixotic

2:28 AM

also I'm really not sure about whether the case could have enough room for the high-end GPUs >_> even modern chassis in ~2008-2009 were having issues with that.

Journeyman Geek

@allquixotic: eh, would you need one?

allquixotic

you'd have to get a new backplate/plane for it too. I'm sure the slot holes for PCI and ISA won't line up to slot holes for PCIe

Journeyman Geek

you could probably happily put in a mid range card

they do!

allquixotic

they do? O_o

Journeyman Geek

The ATX form factor hasn't changed at all

allquixotic

2:30 AM

OK but you'd still need that little piece of flimsyish metal that covers all the ports, right? there was no HDMI or USB back then, right?

Journeyman Geek

@allquixotic: that comes with your motherboard

that's standard too

you just remove the old piece of shitty metal, and put in a new one

allquixotic

I tried doing that once and cut my finger really bad

Journeyman Geek

lol

I think some of my scars have scars

allquixotic

also, the ATX spec does change -- the physical dimensions of the chassis seems not to change, I guess, but other stuff such as the PSU specs are changing all the time (PCIe, new GPU power limits, etc)

and I swear PSUs were traditionally in the top of the case until recently

now they're in the bottom

Journeyman Geek

The screw holes are the same

allquixotic

2:32 AM

*for the cases I've owned since about Nehalem

Journeyman Geek

You just mount them upside down at the bottom of the case, but its the same screwholes

big changes are in cabling standards

not the cases themselves

allquixotic

I bet youtube has a video of some uber high-end box in an ancient case

Journeyman Geek

so a modern system would have more than 4 pins for cpu power, video card power, and sata

but if you weren't too picky you could shove it in any atx case

allquixotic

not all ATX cases will have room for all your storage and expansion slot stuff though; GPU length; etc... if you're just talking about the mobo, CPU, RAM, PSU and minimum cabling to bring that up, then sure

Journeyman Geek

I'd steer clear of systems from major pre-build places (dell for example) for that

@allquixotic: yeah

the screw holes are standard

let me rephrase

Michael Frank

2:36 AM

@allquixotic I'm sure I've said it before, but my old mobo/GFX combo had the GFX card sticking out through the middle of the SATA connectors.

allquixotic

over the weekend, I watched an Alienware unboxing by a Youtube streamer I watch somewhat frequently... he admits he isn't a techie but he's a real gaming enthusiast... I felt really sorry for him D: he must've spent 5 figs for such a system, and it is actually worse than my system in many ways :P

Well I got what u said. I'm running windows 7 ultimate and I have used photoshop, and many other graphic softwares without any trouble(actually in a high speed) on this system just with a 1 GB RAM. I 'vs played many games like NFS IGI1,2,3 on this system. They worked very smoothly and fast. That's why I didn't replace my computer with a new 1. This problem occurred recently. I didn't install any new software nor game. Thats the thing which troubles me. — Iroshan 22 mins ago

it's incredible, the systems people run

my work laptop is a Nehalem i5 with 2 GB of DDR3, which likely runs circles around his box, yet I can barely stand it without an SSD pagefile

Journeyman Geek

lol

@allquixotic: I suspect its your tolerance of pain

allquixotic

the CPU throughput is fine; if I could get 8 GB of RAM, I would be perfectly happy

and I don't need the GPU for anything aside from 2D rendering

Journeyman Geek

I'm tempted to max out the ram on the shared box if its cheap enough

(4gb)

and its actually pretty good for something hitting 7-8 years

allquixotic

did I mention that work has a Nehalem Xeon server with 6 GB of RAM that they want to use as a multi-purpose box with multiple hypervised VMs of different OSes (Windows, RHEL, etc) doing extremely cumbersome database crunching and web serving?

I !!no'ed them as forcefully as possible in email and received no reply

Journeyman Geek

also, windows 7 ultimate = pirated ;p

@allquixotic:ugh.

@JourneymanGeek that guy, or you?

@MichaelFrank: I wonder if you can run a 5 core CPU

@MichaelFrank: those got wiped out years ago

but when I was a pup, I used to buy software like that ;p

allquixotic

the closest thing I did to pirating is slightly bending the license terms of my Dreamspark license of Windows Server 2008 / R2, when I couldn't afford client Win7

they're supposed to be for "evaluation" / "educational" purposes only, and I used it as a general purpose OS for everything

Michael Frank

@JourneymanGeek Yea, interesting that it supported both DDR2 and DDR3

Journeyman Geek

@Bob I thought YouTube was buying Twitch...

Ahh, Twitch decided to go with Amazon as they "believe in their community".

allquixotic

whoa, freaky

I just got a neat idea for a use case of Docker, the container thingy on CentOS 7

install each game into its own Docker container, so they can't interact (incompatible libs etc) and just copy in the userspace AMD driver bits

Journeyman Geek

@allquixotic: docker confuses me ;p

that way, one game which requires an ancient glibc doesn't make me downgrade my entire system, then upgrade it again when another game requires a very new glibc

eh. might gauge interest on used HD7970 and much less-used R9 280X around here or on e-Bay or on Amazon if I decide that I really really want to switch to Linux permanently

(I do, but I need to get things in order first)

Michael Frank

@ChatBotJohnCavil This is possibly the most amazing Cavil error when in context.

allquixotic

I haven't gone green in years because the hardware value proposition isn't there... but the Linux driver definitely wins

can't do the Titan Z; too expensive

Titan Black could be doable

dual 780 would net me similar perf to what I have now

looks like AMD Mantle is on its way to Linux though; that could bode well for Catalyst on Linux in the future

allquixotic

@JourneymanGeek good point

Journeyman Geek

@allquixotic: music is one of the things that keeps me from switching to linux

I have a very nice setup that I'm not sure how to translate to linux ;p

@MichaelFrank: its a command

so, no

You could copy it from another install quite easily

Michael Frank

@JourneymanGeek Thanks. :)

allquixotic

@JourneymanGeek Rhythmbox is more than sufficient for me. And I know that my motherboard's audio chipset works on Linux. I could just live with USB for the input channel and toslink for the output

I actually really, really like Rhythmbox -- so much that I wrote a plugin for it

and Spotify runs on Linux too

Journeyman Geek

@allquixotic: I use foobar2000 with a few plugins. I use WASAPI for example

allquixotic

3:37 AM

also, /usr/bin/env is required by some standard -- POSIX? SUS? not sure, but I've seen it on Solaris, BSD, and Linuxes both new and ancient

so you can pretty much count on it being there on everything except Windows

well. even on Windows, if you're executing a bash script with a shebang, you probably have a MinGW or Cygwin environment with /usr/bin/env

@JourneymanGeek I don't have any particular requirement for WASAPI. Pulseaudio is great.

just need toslink for the output, to get good quality sound to my H Wireless

hmm.. might do a dual boot transitionary period

shrink the NTFS down to 4 TB and use the remaining 3.27 TB of the RAID array for CentOS 7

almost definitely using XFS. ext4 is out of the running. btrfs probably not fast enough. ZFS not stable on Linux yet

Journeyman Geek

@allquixotic: 0_0

iirc xfs is the 'recommended' for Centos 7 anyway

@allquixotic: Wasapi has two advantages for me. Firstly theoratically its better quality

but well

dog ears and all.

(practically speaking, there's a million other more important factors WASAPI off my laptop sound card probably would sound horrid anyway)

secondly, its exclusive so I don't get chat BONGs while listening to music

allquixotic

@JourneymanGeek yup!

Journeyman Geek

I'm probably going back to ubuntu for my torrent box

allquixotic

@JourneymanGeek I actually find the exclusive modes of various sound APIs to be extremely limiting and unacceptable, since I almost always play a game and I want to hear its sound effects at the same time as listening to music

Journeyman Geek

I just can't seem to get rutorrent working on fedora

allquixotic

3:43 AM

@JourneymanGeek get SSH on the public internet (port forwarding or w/e) and I'll fix it for you :P

Journeyman Geek

@allquixotic: in which case I'd just play it, and not bother with fancy audio gear ;p

@allquixotic: I messed that system up quite badly ;p

allquixotic

@JourneymanGeek you'd be impressed at how badly broken of a system I can fix

Journeyman Geek

(tried a script, so I'll need to rebuild anyway)

@allquixotic: you'll essentially be reinstalling it from scratch ;p

allquixotic

@JourneymanGeek hehe

Journeyman Geek

I'm fine with one ubuntu box at home

so, meh, I'll get this reinstalled with ubuntu for now

especially since the big issue I had seems to be hardware related, kinda sorta

allquixotic

3:46 AM

?

Journeyman Geek

and it affects RH alikes worse than ubuntu for some reason

@allquixotic: basically the pci nic I added causes one of the kworker processes to go nuts

allquixotic

:S

Journeyman Geek

I can disable a gpe to fix it, but I don't really need gig-e on that system

allquixotic

maybe it needs interrupt moderation :P

Journeyman Geek

and...

its a known issue with the kernel, just that no one seems to have pegged it down to specific hardware

Michael Frank

3:48 AM

@allquixotic I thought btrfs was supposed to be some kind of super format.

Journeyman Geek

I might make it a question, I'm just more concerned with getting a torrent box again

allquixotic

@MichaelFrank give btrfs another 5 years and it might be as good as ZFS/XFS, but right now, it's got a huge amount of room for optimization that hasn't been implemented yet

the filesystem format is pretty much finalized, and the theory is solid, but actually implementing the damn thing with the meat and bones to be efficient on a variety of workloads is taking longer than expected

right now XFS is the best filesystem on Linux if reliability is your #1 concern, performance #2, and features #3; ext4 is the best if performance is your #1 concern, reliability #2, and features #3; ZFS is the best if features are your #1 concern, performance #2, and reliability #3; btrfs is the best if features are your #1 concern, reliability #2, and performance #3. :P

Michael Frank

concern?

oh.

nevermind.

I was reading the sentence in a strange way.

right now, Android uses ext4 as default; CentOS 7 / RHEL 7 uses XFS as default; Oracle Enterprise Linux uses btrfs as default; and I think Ubuntu still uses ext4

there's no clear winner :P it depends on what you care about

XFS is damn good at reliable performance (no real "worst-case" behavior, which is a huge problem for btrfs), and is a very mature FS with a long history and a focus on correctness

ZFS would probably be the best filesystem on Linux if it weren't released under murky license terms (redistributing code ported from CDDL to GPLv2 is probably illegal), though it needs a lot more stability testing for the POSIX layer (the part integrating into the Linux VFS)

personally, I say: if you're on *BSD or Solaris, always always use ZFS... if you're on Linux, use XFS until a clear alternative emerges

XFS may not be the sexiest choice, but it won't eat your data.

@Keltari Not really, go 32 bit and it'll run basically anything really well (the P4 more so). Same speed as a modern CPU, just a single core though. — krowe 47 mins ago

Uhh...

allquixotic

@krowe "Same speed as a modern CPU" BZZZZT!! Try again. I'm afraid you're off by a factor of... 14. The modern proc having more than twice the single-thread performance, and overall 14 times more performance. That doesn't even take into account the hundreds of architecture improvements on the mainboard (FSB -> DMI, DDR3, removal of bottlenecks and contention, more registers in 64-bit arch, SIMD, and on and on and on...). Just look at those two CPUs! Same GHz, same TDP, 14x perf difference. — allquixotic 1 min ago

I like how it was put on hold as it may become obsolete quickly.

> Do you know NVIDIA, Amazon and ASUS North America on Twitter?

No, Twitter, I don't know those ~~people~~ corporations at all.

@JourneymanGeek lol @ reference to BogoMips

Journeyman Geek

@allquixotic: its true tho ;p

its just as pointless

also, he knows less about processors than he thinks

A little more on RISC: The RISC instruction set is (for the most part) a subset of the full x86 instruction set. Meaning that even if you did manage all of this (by using something like the Pi board) the real world performance would be asymmetrical due to the fact that the number of machine instructions for a RISC operation are not 1:1 with x86 PC architecture. For example, it may do the equivalent of 4+4+4 rather than 4*3 because it doesn't have a multiplication operation but it can still get the same functionality with the addition operation (this is an example, RISC does have multiply). — krowe 53 mins ago

fun part. I never explictly say risc or cisc in my answer.

and snort

My old comments are kinda funny

allquixotic

@JourneymanGeek at least you explicitly spelled explicitly correctly! improvement \o/

Journeyman Geek

@allquixotic: I spellchecked that ;p

speaking of instruction translation...

Transmeta

Transmeta Corporation was an American fabless semiconductor company based in Santa Clara, California. It developed low power x86 compatible microprocessors based on a VLIW core and a software layer called Code Morphing Software. Code Morphing Software consisted of an interpreter, a runtime system and a dynamic binary translator. x86 instructions were first interpreted one instruction at a time and profiled, then depending upon the frequency of execution of a code block, CMS would progressively generate more optimized translations. The VLIW core implemented features specifically designed ...

I didn't realise ~~patent troll inc~~ intellectual ventures bought them

allquixotic

aha, Linus "Fuck You, Nvidia!" Torvalds' old company.

Journeyman Geek

yup

their tech is pretty cool

(and you probably see it everywhere ;p)

allquixotic

Linus knows a ton about x86 assembly and native code; that's really his domain

Journeyman Geek

@allquixotic: probably why he was useful

allquixotic

he doesn't grok a LOT of the stuff that third party devs are contributing to the kernel these days, but when something x86 related comes by, he is usually highly critical of it if it isn't perfect

Journeyman Geek

oh... 5 more days to centaur technology's new website.

(granted, via has not done anything interesting in the x86 market in eons)

@allquixotic: at this point, he dosen't really need to

@allquixotic It wouldn't work to have a benchmark which leveled out once you hit Y2K CPUs would it? In the real world, you're probably going do go with a less modern OS. Going from 64 bit to 32 bit will nearly double your speed as well as double the effective RAM. Add the fact that, even though these older CPUs are hotter per core, they have less overall heat to dissipate to begin with and you can probably run it closer to 4Ghz on air. You aren't playing the latest blockbuster games & you'll notice < mem bus and 1xcore but it really isn't too bad. Still beats your average tablet experience. — krowe 2 hours ago

say what

I don't even want to reply to that, it's so utterly wrong. I could write an essay on the problems in those claims.

Certainly not enough space to address all of it in a comment -_-

Every single sentence is a "wat"

Journeyman Geek

rofl

Bob

Sentence 1: "Y2K CPUs", benchmarks "leveling out"?

Journeyman Geek

do go?

Bob

Sentence 2: Why would you "go with a less modern OS" "in the real world"? And the assumption that a more modern OS necessarily needs more resources is also wrong...

Journeyman Geek

yup

Bob

7:28 AM

Sentence 3: ...you ain't doubling speed by going from x86-64 to x86-32. consider the former has more available registers, that the registers are wider (and therefore can handle 64-bit math more efficiently). Also, memory usage on 64-bit is nowhere near double

Sentence 4: ...I'm not even sure what this is saying. Older CPUs "have less overall heat to dissipate"?

100W TDP is 100W TDP is 100W TDP

Journeyman Geek

yup

Bob

Sentence 5: ..."latest blockbuster games"? mate, we ain't gonna manage to run MS Word smoothly on that old thing

Journeyman Geek

actually, modern cpus almost certainly dissipate less heat, and are a lot more efficient

Bob

Ya. See: Pentium 4 :P

Journeyman Geek

actually, the pentium 4 singlehandedly ended the clock speed war ;p

Bob

7:31 AM

Sentence 6: Consider your average mid-high-range tablet has equal or more RAM, then think about that sentence again.

@JourneymanGeek More because they realised just how shit it was :P

Journeyman Geek

@Bob: and their own mobile processors were kicking its ass badly

This question was deleted by the asker while I got distracted while typing up an answer. It seems to be a legitimate question (it's answered in the relevant man page, but the answer is somewhat well hidden and not completely obvious to someone unfamiliar with the concepts), and I couldn't easily find something else on site that explains the OP's problem. I voted to undelete, but a few more pairs of eyes taking a look and voting appropriately would be nice.
