I run GigE between two Win32 platforms and my Linux fileserver. I still manage to get about 20-40MB (megabytes)/s between the systems when reading or writing to disks over the LAN.
Using two Intel EEPro1000MT, a NetGear GA302(?) and an el cheapo Fry's special GigE 8-port switch and single drives (no RAID/LVM) on PATA or SATA.
Actually, you might be able to find some passive electrical rate measuring devices for doing fancy electric use graphing or whatnot... Not that I've actually seen such a device >.> Better to future-plan anyways.
Also, here has some ideas on what to do with the cabling. It's a good idea to have too many cables run than not enough and find out later that you need a drop in a place that you had second doubts about, i.e. my former residence has three cat5e drops per one-gang box: two data, one voice. Some even had an RG-6 for cable TV.
On the GigE, I can send about 40MBi/s from the drives. My 60MBi/s is from sending data from/dev/zero on the linux system to a ramdrive on the win2k system (yay, 2gb memory). MRTG/rrdtool hasn't been too bad on reporting bandwidth use in the past in other implementations (mainly datacenter bandwidth useage). Mind you, the switch was a $50 special at Fry's about 18 months ago.

Active machines: 1 Linux server/workstation (SMBfs, LAMP, etc...) 1 Win2k workstation 1 WinXPPro PVR (hooked up to a 27" TV, BeyondTV) 1 IBM ThinkPad 600 [XPPro](primary system) 1 Apple iBook 600mhz [OSX 10.3.9](on it's deathbed) 1 Dell Latitude D600 [XPPro, FC3](work laptop)
Dead/Inactive 6 Macs (PM6100, PM9600, 2 G3 servers, two classic 680x0-based systems; all operational) 2 dead laptops 2 dead desktops pending recycling
The desktops are all using Intel eepro1000 GigE workstation NICs connected to a cheap GigE switch (I've maxed it out at 60MB/s thruput:/ ) The switch is connected to a WRT54G WAP/Router (using stock firmware, I've a second WRT54G that I'm playing with the Sveasoft firmware on). This all connects up to the housemate's Cayman DSL adaptor/router.
I've never been a fan of the low-profile Maxtor drives. I run a helldesk for a reasonably large company's satellite office and have approx 150 d530cmt's on active deployment at this location. Though, my failure rate is quite a bit less: in the 6 months I've been here I've only had one dead drive. The tech before me had two over the life of the deployment (late 2003 ~ Dec'04, I believe) while she was there.
I agree. This is a service offered by the State. You don't have to use it. If you do use it, you are bound by their ToS. If you don't like their ToS, don't use it. It works the same way with commercial ISPs as with state funded services. If the State were trying to regulate other service providers, I would take issue, but they are self-regulating. I don't see what the issue is here.
What do you base your "commute hundreds of miles" comment off? I have friends that work in Tokyo, Osaka and a city in Hokkaido that I can't remember the name of, and their commutes are 20 miles or less.
No, if anyone knows anything about RFI or EMI, the talk is to put a layer of foil or braid under the cover of the passport, making a very simple and effective Farady cage.
I just need to remember where I put the authoring tools, the server application and the desk-side apps. If you set the client to look at your server and not the now defunct PointCast servers, you might be able to get it to work. (I did this for the business customers of the ISP that I worked for back in Tennessee... the suits really enjoyed it)
I agree, I *really* miss PointCast. I can't believe that someone didn't buy the tech or IP and implement it somewhere else. Shame.
You think it could be considered 'abandonware' yet?
For unlicensed operators in that band-plan (for the most part in the US, non-ham radio operators and those that don't have specific licenses from the FCC for that band region), you are limited to 250mW of PEP (peak envelope power, I forget how it's measured [either at the jack or from a distance]).
If you're good with securing your computer, you might want to see if one of your dorm neighbors would be willing to share his/her wireless connection, thus removing one 'polluting' access point from the building.
Try telling this to someone who repeatedly built 2.0.x kernels on a 386/16.:P Albeit, I had to let it run overnight (and sometimes up through lunch too), but it's most definitely doable. Highly recommended if you have nothing better to do with your time.
Run this on each of your drives, replacing hdX with the appropriate designator. This ~should be~ your maximal thruput to your NIC, unless you are testing individual drives on a SoftRAID setup.
Eh, my 1995 Oldsmobile 88 with 120,123 miles on it *still* gets 30+ MPG highway. Mind you, it doesn't get it here in San Diego where the hills will crap out -anyones- mileage in a heartbeat, but it still manages to eek out ~23 MPG highway down Interstate 5 from the Orange County line to Clairemont Mesa (about 45 miles). All this from a full sized, 3.8 litre V6 that comfortably sits 5 adults with a curb weight of just under two tons.
Never mind the car is approaching 10 years old.
Since Oldsmobile has been discontiuned, you might want to look at the Buick Century or LeSabre. Same chassis code and the exact same engine that's been used in a good number of GM products since the 3800 Series II engine came out in 1995 (iirc). Oh yeah, my car also qualifies as a LEV. Try getting that with an SUV.
Oh yeah. I feel more safe in this car than my previous two vehicles, a 1984 Chevy C-10 pickup and a 1995 Sonoma SLS.

Can you not read? I explicitly said 'bridging clips' in my posts! The 66-block that I purchased from Graybar *did* infact come with the bridging clips and they were used as specified, to bridge the two center columns of pins for each row. Input on the left column of pins, output on the right column of pins, bridge clips in between. I've been wiring things like this for the past couple years, I do think that I know what I'm doing (including contracts for AT&T, BellSouth and General Dynamics)
And for point of info, Jury rigging has only been mentioned by me! If I could take a picture of the block maybe you can understand what the hell I did. Sheesh.
I believe that the $50 invested in a good crimper is worth the money. Besides, you'll have a couple bad crimps here and there, but after a while you'll get pretty damn good at it and maybe have a failure once every 100 or so crimps (my going rate right now). One of the most usefull skills I've learned was making a proper TIA-568B cable (what everyone calls Cat5 patch cable).
Add to that that you can make the enclosure look nice and professional looking by having little slack in the cables. Makes for a nice bragging piece to the non-networking initiated (ooo cables and blinkey lights!).
Which reminds me, I need to scour Graybar for more RJ48 connectors, my bag is looking rather lean.
