    Re: How to fix a laptop that got coffee spilled on it

    The term for this kind of set up is 'SOHO' - small office/home office. And the demands don't typically exceed what most home networks have these days. You can call it a small office, but it's really not different from a well-utilized home network.

    Re: How to fix a laptop that got coffee spilled on it

    I know that I don't need the speed, but I don't know what I will need in the future, more likely less instead of more, but never know and I don't want to fish the wire again (have to cut out some sheet rock and patch afterward) to get to one end of the conduit, the fact that I have to do it, pisses me off no no end, my plan was originally to grab 4 pairs from the phone cable and put an RJ45 connector on each end, it would be so simple

    or should I try that, running data over 160 feet of phone line ?

    You will not exceed the bandwidth of the Cat 5e in this application in your lifetime.

    and you know this because ?

    in my short 50 year career, I have seen land surveying go from 5 man field crews and computations by adding logarithms long hand, to one man robotic total stations that can laser scan objects or land surface creating millions of data points in just a few moments, the older I get, the bigger and quicker the leaps in technology

    Cat5E is good for gigabit speeds, which is 1000mbps, or 125 megabytes per second. Most computer nerds will struggle to saturate that in any meaningful way.

    It's only fairly recent that gigabit has started to become standard on consumer equipment. Mildly older stuff will still be limited to 100mbps network thru-put. The network utilization is also limited by how fast your hard drive can read/write. And the creation of that many data-points is also likely limited by the processing power of the device creating them.

    Bottom line, I don't think there's any harm that can come from running Cat6 or 7. But I doubt you'll be needing more than gigabit even remotely soon.

    Because this is what some of us do for our job. We recognize trends in bandwidth utilization and plan long term for link capability.


    I have dorms filled with 40-100 teenagers using multiple devices at once that don't come anywhere close to utilizing a one gig pipe feeding the building.

    I mean, if you want to run Cat 7 since it's not expensive, then go nuts, it won't hurt. But you won't fully utilize a gig pipe between your house (web surfing/video streaming) and your office in your lifetime. Nevermind a 10G.

    not concerned about video streaming, I will be setting up a CAD workstation in the house, some of my drawings are several gigabits in size, on my server.... except for one, all my workstations have SSD

    And still, this is just basic file IO. Nothing that will be maxing it out.

    Run Cat 7 if it's the same cost or similar, but sleep easy. You won't end up needing more than a gig.

    Re: How to fix a laptop that got coffee spilled on it

    Randy, fuck man. Listen. We understand perfectly what your application is. Clayton was using that as an example because it's bandwidth intensive. You also need to understand that unless every component in your home network is 10 gig capable (Cables, switches, routers, NIC cards, etc..) you won't achieve 10 gig transfer speeds. What you really need to realize is that your application doesn't require anywhere close to 10 gig speeds. For example, my company processes databases that result in many terabytes of data over our network all day every day. We have 3 programmers and 6 data processing techs. Our network cabling is mostly all gigabit (Cat 5e) and our network performance is typically fine.

    A CAD file of 5 gigabytes will take approximately 5 seconds to send across a gigabit network.

    Again, do whatever-the-fuck you want, seriously. Hook up the god damned phone line if that's what makes you happy. But you're the guy who asked the question so don't get mad because we're calling your network traffic small.

    you say that, but I've seen the size of cad files grow and grow and grow, with laser scanning now, hundreds of millions of points with their corresponding data

    If you want some headroom, then go fiber. Even OM3 MMF is capable of hitting 100Gbase over those distances quite easily.

    Then you've answered your own question, run two CAT7 lines, 'cause you know, future growth. If you have any more questions you would like to answer yourself, shoot.

    Only If you have a computer capable of writing at gigabit speeds. Id bet money that isnt the case.

    Large file transfers are near meaningless in this context. Its the difference between waiting a minute or three. Its more important for something that needs real time data streaming. Especially multiple streams simultaniously. And i think itll be a while till that becomes an issue.

    Re: How to fix a laptop that got coffee spilled on it

    This whole conversation makes me chuckle.

    I understand what all of you are saying when telling Randy not to worry about not having enough usage to top out the cat5e cabling but I also understand why Randy is coming back with the points he is coming back with. Remember back in the not so distant past when the first 1gig hard drives came out and everyone was all "who needs 1gig of storage nobody will ever need that much storage" Now we have thumb drives and cell phones with way more than that and people still run out of space. If the cost isn't dramatically different it could make sense to go with the cabling with the most available capacity now to possibly prevent obsolescence down the road due to some unforeseen development in technology that might make cat5e not viable.

    I'm sure the poor dead horse will continue to be beaten down though and I will happily continue to read the posts because as a jolly fat guy I can't refuse a good chuckle when I see an opportunity.

    I remember when we stored data on punch cards, and before that, as I said, doing calculations by manually adding logarithms or for quick & dirty use a slide rule. Now, I have a 2 terabyte ssd server that is nearly half full

    The keys themselves can be individually removed as well. But that can be annoying. I'd probably get the keyboard itself out. Give it a good shaking. Then put it somewhere dry for a few hours.

    If this was fairly recently, hopefully it's just liquid left over messing with your key contacts. But a replacement keyboard off ebay is usually pretty easy.
    I spilled soda and the buttons solidified. It was easy. I took it all apart and washed all the buttons and tiny springs , etc in the sink with dish soap. The only mistake I made was not taking a picture of where all the letters and number and stuff went. So I had to figure that out.

    Randy throw an extra wire in the ditch, back up and growth, wire is cheap

    Now if you have gig files get the boys to talk solid state drives

    you can dig a ditch if you like, I had the foresight to bury a conduit with a string in it. about half my network is solid state drives, and fwiw, I no longer have employees, doing it all on my own now

    Randy,, FYI we had a good Peep SHow about 15 guys including the Canadians
