I'm running SuSe 9.2 (good functionality, not exactly stable for me) and I keep a 12.0 gig crypto filesystem on my 20.0 gig drive.
The passphrase is sort of English, not shared at all with anyone, and I can do most of my work without mounting that stuff at all. When mounted the partition is a attached to/vmware and it contains a Windows 2000 install with my accounting stuff and maybe a few other operating systems for play. The accounting stuff is the only thing I have that qualifies as 'sensitive' - VMWare+crypto lets me carry it securely and easily back it up - I've got another sizeable CFS partition on my desktop at my office.
Physical security is a huge issue that most computer nerds ignore - its not nearly as sexy as configuring a firewall - all discipline and no play, so to speak.
It says the central U.S. is wetter but the man made lakes in western Nebraska are toast - McConaughy is at something like 32% of full and they're going to dry up three smaller downstream lakes to keep it at least partially full next summer.
Maybe its a fifty year average and the last five have been bad...
Have *you* modulated the signal from a microwave oven? Those things are 2450.00000MHz and they don't twitch no matter what you do with them.
When PCS came to this area I helped a ham haul an 8' 1.9 GHz dish away that had been decommissioned from a licensed band network. He was talking moon bounce with that. Sure, SWR is a little funny matching 2.4 GHz source to 1.9GHz antenna, but 8' of dish free for the hauling? Ya gotta try it...
I'm saying that 802.11b/g occupies the frequencies between 2402 and 2483 MHz, with eleven 22 MHz wide channels, and only channels 1, 6, and 11 do not overlap each other. (OSI Layer 1).
I'm saying that the 802.11 MAC layer is *shared* amongst all cells that can receive each other's signals, and that this MAC layer sharing is below SSID, WEP, or anything else one does to make a cell unique and secure. 802.11b/g uses carrier sense multiple access with collision avoidance (CSMA/CA) which is sort of like ethernet, only not really. Depending on RTS/CTS, fragmentation settings, and the phase of the moon, 802.11 systems respect the network allocation vector(NAV) from other systems. (OSI Layer 2)
I'll try to say this without sounding snotty, but I am quite congested from the flu, so YMMV.
The typical Slashdot reader's understanding of the realities of radio are fairly consistent with their understanding of women.
If one spends a bit of time with google and certain keywords one can find women with silicone or saline enhancements. Slashdotters with little real world experience in radio will examine a wireless article proclaiming 108 mbits of cup overflowing throughput and assume this is their god given right, not understanding that paid professionals produced that number, and that such things are only possible in the real world with *very* tight constraints.
Further google searching will turn up overdone silicone enhancement in *very* close proximity, cooperating in a seamless fashion to deliver service on channels one, six, and eleven. Despite such configurations being much photographed, complete with a delirious Slashdot reader enjoying the full throughput on all channels, the real world *never* lives up to such grand designs. Getting even two channels worth of such service usually depends on using channels one and eleven with highly directional antennas so they never see each other, and the odds of getting both to play well in the same room for any length of time is well nigh impossible.
Long distance relationships might work, but there are definitely bandwidth issues. The inverse square law applies to all Slashdot squares, and smokin' hot performance at short range rapidly grows cold as distance increases.
Now I'm just riffing here, much as you were, so I'll close by attributing your excellent cordless electronic device performance to the firm grip you use to wield the machine and much practice in the 900 number band.
You may not use more than one watt without automatic power control per FCC part 97. You will not find amplifiers with more than about ten watts of output in the 2.4GHz band as that is plenty for most amateur television work. The limit for HAMs is 1.5 kilowatts in most bands. A man named Riley Hollingsworth will help you understand if you're one of those poor souls who is confused enough to do such things, but organized enough to actually pull it off.
The 802.11b/g spectrum is being loved to death in your building. If you've got twenty devices trying to share only three non overlapping channels (1,6,11) its a mess if anyone wants to go fast.
Setting the channel is the first step but you'll still get adjacent channel interference. Setting SSID *DOES* *NOT* *HELP*, nor does WEP/WPA. SSIDs define a group of nodes that are going to associate but the media layer (OSI layer 2) is *shared* for 802.11. That means two properly secured networks on different channels are still sharing the same stream of NAV (network allocation vectors) and they'll be stepping all over each other.
I could go on about this but I've got the flu and you've got internet access - get Matthew S. Gast's fine O'Reilly book on 802.11 and learn all the gory details for youself.
I got all excited there for a second with visions of covering downtown with some good, commercial free music. 100mw and a short feed to a good antenna on the roof of my building would have done the trick for many blocks around me.
I looked into a 'real' low power FM setup and it seems you have to be a 501C3 religious or educational organization, can't use directional antennas, can't look funny at people on the street, can't name your cat Morris, have to blow the FCC OO, and that was just the rules for the first page - quite a lot of work for the privilege of spending $6,000, eh?
Maybe I'll just hook the 300mw unit to my attic 2m and run it when the mood takes me:-)
I've been on 2m/70cm for a couple of years with a technician's ticket. There are a few old grouches, your usual collection of mental patients with enough sense to find the FCC approved testing facility, but most operators are nice to the new guys.
There is an entire culture to ham radio, just as there is on the internet, but its very different. HAMs have to be polite by law and this is as deeply ingrained in the culture as flaming people was on Usenet back when. The internet could do with a bit more of this attitude, IMHO.
If you have a HAM tech ticket you can run 802.11b at 1,500 watts, so long as you rig up some sort of automatic power control. Realistically you won't be able to buy more than about a ten watt amp, but ten is much more than the one watt units allowed to those pesky wireless ISPs:)
WANFORCE was an aftermarket networking equipment company based in the St. Louis area. I saw this article, called a friend who is still in the business, and Peter Roberts died some time in December. The official cause was listed as 'heart attack', but at age 34 given the other stuff that was going on around these guys we're 99.44% sure it was cocaine overdose that got him.
My contact said "they're both swindlers, but Tim is better at it than Peter was". A sad epitaph for Peter and hopefully a message that will lead Tim to mend his ways.
I've got twenty or so FBSD boxes on the net at various locations. The one 5.3 box I have requires more attention than all the rest of the 4.9/4.10 systems out there. I love FreeBSD but I pronounce 5.x 'NOT DONE'.
The Grateful Dead alternated between fabulous and miserable throughout their career, but their work requires that you listen to most all of it to genuinely understand.
The Other Ones did some truly amazing work all on their own and it hurts me greatly that I never got to see them live. I saw The Dead last summer and I was not terribly impressed - some much loved standards played, Down The Road is very touching, but the song to song fusion just isn't there with the new line up. Perhaps they'll improve in time, or maybe I'll wander off to String Cheese Incident...
Free full concernts from Widespread Panic, Grateful Dead, Phish, String Cheese Incident, and many others - all perfectly legal. Why piss and moan about the RIAA when you can escape their crapola free of charge? Because you're conditioned to listen to junk is one possible answer to that question:-)
I lived with this chick that had a cable chewing cat some years ago. One day one of my college roomies stopped by and as we were talking kitty walks out and starts in on the phone line in the living room.
Mike looked at me, got the *biggest* grin you've ever seen, then whipped out his cell phone and pressed redial...
Kitty rang, backed up, hissed, then bit the cable again just in time for the third ring. Now I liked that cat and I have a long hair tortoise shell of my own, but I sure was glad that Mike cured that cat of ripping up cables.
I've seen Widespread Panic three times in the last three years. I've seen Phish maybe six times, the Grateful Dead twice, and a bunch of other stuff in college. I am too old for the tour scene but I do try to get out to one real show every year.
I've just counted - 36 shows, one more on the way tonight. I don't think I've listened to them all, however... I need to keep notes since I'm not familiar enough yet to pick out what year I'm hearing.
I love bittorrent - I have about forty full length jam band shows that I've obtained over the last couple of months from www.digitalpanic.org.
I have an office cable modem, a home cable modem, a girlfriend's house cable modem, a mom's house cable modem, and most of them have BSD boxes for firewalls. I'm working on a method to automate the three home boxes participating in torrents I seed so when I start distributing shows I'll come with a megabit of bandwidth. Once the process is 'cooked' I have a couple of customers that probably won't mind some torrent activity on their network, so long as I keep it between 9:00 PM and 6:00 AM.
If you worry about the RIAA the solution is simple; get interested in bands that *promote* your right to copy their live work - Widespread Panic, Grateful Dead, Phish, Moe, Jerry Joseph & Jackmormons, String Cheese Incident, Government Mule, Drive By Truckers, Southern Bitch, Star Tangled Angel Revival, and a hundred other, less famous acts I've haven't listened to yet. There *is* something there for everyone:-)
I hold the Cisco Certified Network and Design Profesional ratings and only the MPLS exam stands between me and the Cisco Certified Internetwork Professional ticket, which means I've had the pleasure of the Cisco DQOS exam recently.
I used to work for an international voice carrier and I've had my hands in various VoIP projects for about the last five years. I have one customer with a six node Cisco VoIP over low speed frame network, another with a five site contraption that does VoIP and video over point to point frame encapsulated T1s, and I'm in preliminary discussions with investors on starting a VoIP centrex of CLEC service in my city.
I'm within driving distance of you, things are slack at the end of the year, and I used to work for what is the third or fourth largest used Cisco shop in the country - I can stop there, pick up a bunch of Cisco VoIP toys, and head your way.
You can email me, bliss at ignorant dot org, if this sounds like a possible solution.
Right on, brother! I've been moving stuff around tonight in terms of BSD boxes and it took a bit to get 34 full concerts @ 29 gig moved from a retirement age drive to new storage. FLAC rocks and I get quite a bit of stuff in shorten format as well.
http://www.digitalpanic.org is a fountain of torrent files for entire shows by Widespread Panic, Jerry Joseph and the Jack Mormons, Grateful Dead, Phish, etc, etc, etc
That is only a little funny, but I'm glad to see people considering the options.
Would it be fun to...
have a wireless bluetooth adapter to an EEG cap? You could do various physical activities and check out what your brain was doing during the process. I'm thinking Vinyasa yoga, myself, but I'm sure you can imagine other activities that would be interesting to record and visualize later.
Such toys already exist, but I don't see any FOSS stuff. Someone needs to produce EEG stuffs, interface card, and make the software free so we can all play.
This looks like it isn't very complex nor very expensive - 64 electrical sensors in a cap and a PCI card with 64 inputs for A to D conversion- looks like less than $500 in volume, perhaps only $200.
You can do infinite numbers of fun things, first one that comes to mind is a brain wave visualization plugin for XMMS.
If I got the soldering iron out my roomie would dial 9, 1, and have his finger hovering above the 1 button:-)
I am going to talk to this hardware guy I know and see if we can make an FXS to WISMO converter... thanks for the tip, will post here if we get it going.
I do a lot of work with Cisco equipment. There are a variety of voice capable routers but lets use the one I have in my office for testing as an example.
The device is a Cisco 1750-2V. It has onboard ethernet, one slot for a WIC (data), one slot for a VIC(voice), and one slot that can be either data or voice. I have a VIC-2FXS and a VIC-2FXO available. The FXS device provides ring generation - that 48 volt battery you mentioned. The FXO device acccepts ring generation and can be used to connect a telco analog line to the VoIP network.
There are other interfaces available - VIC-2E&M which is a phone system to phone system trunking interface, T1 and E1, etc, but those are not relevant for this dicussion.
I'd like to have a device that could be hooked to either the FXS and accept the 48 volt ring or the FXO and provide a 48 volt ring, with the 'other side' being a cellular network. You describe a method to make the product work with a PC and that is an interesting hack, but I want to make money with it promptly.
Think about how cellular is these days - free calling on net. Imagine an office with ten guys packing phones from the same carrier - they can call each other for free but they burn minutes when they have to call the office. If you have an FXS/FXO to cellular device you'd be able to take advantage of the free on net calling.
Cell companies *won't* provide this because it would eat into their revenue. Given that they make money when calls terminate off their network it will take some enterprising hardware hacker to build and market this device.
