I wonder what speeds could be achieved over a radio link. I have a few good friends that are hams, and we are always complaining about the fact that we are 20 miles apart without line of sight, which rules out the possibility of a high speed link. We talk over voice links all the time, but the fastest we can get without line of sight with of the shelf hardware is 9600 baud(38400 if we could get ahold of some data radios). The problem is that for each packet the transmitter has to be keyed up, sends a preamble, then sends a IP packet wrapped in a fake AX25 header. Sure, these are the links that TCP/IP was designed for, but we have come along way since then. The only time I have seen people play Q3 over ham radio(A wonderful use of our spectrum) was over microwave links. I know 56k/78k equipment does exist, but I don't feel like shelling out 800 bucks at each end for those speeds.
I forgot to add:
I am currently taking Japanese as a foreign language, but the primary language I use is German. I have never taken a class on it, but I have been reading it so long "it just makes scense".
How about we have games only render objects that will most likely be shown in the scene? Besides making these "cheat drivers" impossible, it would probably increase the frame rates by having the processesor do some of the work(would really speed up NVidia based cards).
Hey, anyone know if any single disk distros support mosix or is it small enough to just recompile and add a startup script to the disk? At school, all of the stupid teacers are microsoft trained(EVIL), but after the sixth period bell rings most of the machines boot linux. We run around to all the machines and set them to recieve the latest multicasted HD image among other things. If the machines boot linux from the hard drive all the "microsoft monkeys" run around screeming, but we regularly boot it from floppies when we actually neeed to use a computer or mess with the network. A single disk to run around with after school so we could get large jobs done would be great!
I have never ordered through SWBell, but often you can ask for an alarm circuit/LAD circuit. These are not conditioned for data(about $170/month), but they work most of the time(alarm circuits are usually $20/month).
Ok what if I had a pair of ADSL modems(westell wirespeeds) from Pacbell. I see a lot of info about HDSL/SDSL, but what would two ADSL modems do when plugged into each other(the wirespeeds claim 8mbps down 800k up)? Would they sync at 800k? Using ADSL modems seems cost efficent(a lot of my friends have 2 or 3 from cancled orders), but they don't use the first 64KHz of the line where the quality is the best, as SDSL does(adsl piggybacks on voice, sdsl uses a dry pair). Any info(maybe I could convince a neighbor to let me use their modem for a day and see if they sync)?
Ok, this is mostly addressed to those people yelling "1GHz x86 faster than 500MHz workstation(yeach, there are 8 cpus, but still at 500MHz)" running much more effiencent code than their windows box...
Since when was a wireless technological advance measuread with a center frequency? What does this have to do with technology? Why can't I have a PCS signal down at 400MHz? Only because there is more space at 1.9GHz!!! It makes absolutly no sense to me. Oh, I have a 1200 baud link at 10gigs, so it must be faster than my 220meg link. So antennas change at the higher freqs., but it has nothing to do with technology.
I'm sorry,
I thought every GPL software author was getting payed back by getting more free software. By releasing software, you exposed people to the ideals of free software, which in turn cuases most to release their works for free. The software is exposed much quicker than if you had to pay for it, which basically caused the free software explosion(people have been releasing free software for years, but not the source, so the explosion didn't happen until the GPL became popular). Once we pollute GPL software with download charges, we quickly:
Slow down the evolution of software
Cause more people to charge for their software
Cause distros to pay for included software
Compound the price
Eventually close source to prevent Stealing
Destroy this free software explosion
Become Greedy
Have the previous exponentially compound

Yeah, I have a upgraded sparcstation 2(with the 2x cpu upgrade, a whopping 80MHz) and its big monitor. Adapters exist to feed the monitors from VGA(you can buy or build them), however the monitors are fixed frequency, so you can only use them when your machine outputs the exact sync, and your probably have to open the monitor up and play with the fine tuning. BTW, the optical mouse pads work wonderfully with the new breed of optical mice.

Ha ha, btw, I forgot add my rant about consumer DVD software to my previous post. Although the quality of most hardware DVD players is excelent, I really hate most DVD playing software. Complete hardware and studio quality software is ok, but most of that MMX accelerated windows stuff is horrible. MMX has some good uses for approximations and stuff, but should never touch actualy data(IMHO). Most of the windows players I have seen, and some linux players(thankfully most can turn off MMX acc., but they don't look as bad as the windows players in the first place), seem to have "noise", which really annoys me. If I use a good algo to decode, this "noise" goes away. Too bad for me if I have to decode on a dual athalon for full speed;). Hmm.
-- I am listening to 128k streaming music right now, wishing that I could lug around an ADAT and an ups for power in my backpack so it could actually sound good.
Actually, I am quite pleased someone actually has the source to their videos availible for once. Every time I get a trailer, or a cool movie, I usually end up asking the author for a vob/mpeg2 version. 90% of the time they laugh, sometimes the actually give me one. I like downloading those small, horrible looking, headache inducing, small videos as a preveiw(which in this case, wasn't availible), and if the first thing that goes through my head isn't "this sucks", I usually try to get a vob. Thank you for actually posting the full video, although it would have been nice to include a DiVX version as a preview(which I could make easily, its just the servers/my net connection is pretty loaded, so it might take me a while to get the source).
If I recall correctly, the new versions of WMP have a menu option to back up keys(Tools:License_Management). They say if you ever move computers, you music will not play, unless you move the key backups too. After you restore the backups through WMP, all the music from your old computer will play fine. Seems to me people could distribute their key files along with the pirated music. Just following microsofts instructions on how to pirate stuff;)
Ok, so they shoved input from the probes in to a neural net and trained it for a while(they didn't really say how long it took). Thats nice, but would it need to be trained fully before every flight(pilot had coke with lunch, caffine level high, please retrain). Could they have a template net that would be a general starting point for training, and then it could adapt to the pilot? And would the net continue to learn during the flight? It could be bad, because the control characteristics would change between takeoff and landing, but could also be benificial, with the pilot's caffine level. But then again neural nets aren't always predictable if you keep them learning(just look at humans). Anyone have experience with stuff like this.
Ok, I'm sick of these "recent security problems" with Linux. Have I been out of the loop here? I mean, I heared about problems with the default install of redhat, but those weren't holes is Linux. I bet I could take any network enabled OS, run a service(like a shell bound to port 8080) with all the access rights in the universe(as far as the OS in concerned), and let people hax04r away at it. Although a lot of the MCSEs out there think of redhat as linux, I believe the only true linux is the kernel. Then we have the GNU tools that are commonly installled, which many associate with linux, and then we have the pretty Boated-Do-It-All_For-You-'cause-You-Will_Assume-it s-Secure installers. I could probably configure any network enabled and disk writing OS to be insecure if I had the time.
This is kind of off topic(but I think it is worth it 'cause I am losing my moderator rights for this post), but aren't degrees(C) nonlinear? Isn't kelvin the only [common] linear unit of temperature? I always get mad at my science teachers when they use differences in temperatures that aren't kelvin? Before I have to yell at my sci. teachers about this again could someone please tell me if I am correct.
A computer without Windows is like icecream without ketchup -- Heard that somewhere
Increasing the bit depth from one bit(2^1= 2 shades of gray) to three bits(2^3 8 shades)increases the complexity of the read and write process. More error correction would have to be present on these discs, and although at the same rotational speed these discs have three times the data rate(3x density increase), we can run into problems. Our current burners have enough time at 1/4 of the complexity of these discs. When burning current discs, 52% intensity is rounded to 100%, and 49% is rounded to 0%(in a perfect world). With 8 shades we can't do this, and would have to slow down the burning process to insure accuracy, and on an IDE bus(consumer equipment) couldn't supply 3x the bitrate of current burners anyway(anyone ever had buffer-underruns). So we would have to decrease the burn rate to that of current burners because of bus-throuput(SCSI doesn't have this problem), and decrease it further for accuracy. Reads still get pulled off a little faster, but seek time would stay the same. I would say 2x faster sequential reads and.5x burns in this "faster" technology.
I have been a long time skeptic of any CISC arch. Lately, instead of people designing programs around a computer, Intel has been designing a computer around the code. The Pentium 4 cores were being designed WHILE DivX got its time in the spotlight. SSE2 was designed to work on DivX, and anything else Intel predicted would become big during the Pentium 4's lifetime. When the next new wide spread method of compresson comes out, we will have to upgrade to Pentium 5s!
RISC archs on the other hand seem to be geared more twards a general purpose processor, not just what Intel thinks computing should be like. When MP3s became big, it was a nightmare to create a fast iDCT on the x86 archs. On RISCs is was(and still is), a piece of cake. Simple programs take forever to execute on current X86s, but their RISC counterparts can blow through anything with almost no effort. RISC processors were designed for "computers", while CISC processors were designed mostly for machine controllers(anyone remember the stop-light tutorial on the early Intel CPUs!) and other things doing predictible repeating tasks.
Specialized vector processors are the other main type(in my eyes) of processor on the market. They are extremely single purpose, and are extremely fast. Someone could create a DivX-on-a-chip that could process a frame per clock cycle, run it at 10MHz, and blow every other CPU out of the water with >"real time" multichannel DivX encoding on one chip! This is where I am afraid Intel is going. Their chips can still run normal "computer" instructions at a small fraction of the speed of a RISC cpu at half the clock speed, but can run at an exceptable speed with most "consumer" low-grade multimedia(Don't get me started on my MMX is evil speech that everyone hears me give).
I would really like to see this SSE2 code that was "hacked" into FlasK. Even more interesting might be the dissassembled code that Intel's compiler produced. For all I know Intel could have done something as simple as recompiling FlasK in their standardized compiler, instead of something Microsoft produced.
If everyone was running LinuxPPC \ Linux/Alpha I would have no need to write this;)
BTW - Anyone working on a Linux-FPGA project?
Recompile your kernel and write it to your processors microcode-ROM. hehehe
I recently played the the beta GTH system, and even with only a few beta testers on it, it doesn't work.
I know about the whole speed of light thing(which is where most of the latency comes from), but sharing an uplink makes it worse. The problem is that although data is always streaming on the downlink side, people have to take turns transmitting. For example, when I was the only user with data to transmit, my ping times to the first router were ~700ms (pure speed-o-light), but when one person was ahead of me to transmit a packet, it quickly went to ~1500ms, then ~2400ms, etc. When someone is ahead of you to transmit you have to wait for them to stop transmitting data, for their transmitter to shut down, your transiever's rx-tx turnaround, your transmitter to come on, and then you can finally get your packet out. Imagine this whole sequence with ten people ahead of you(if the service became widespread, this could become very common)!
The other problem is that people with defective transmitters(or malicous people who modified them), could easily jam the transponder being used for the uplink. If someone is transmitting continuously(knowingly or unknowing), A SINGLE USER COULD TAKE DOWN THE WHOLE SYSTEM! How's that for bad security!
Nautilus is a free(and open-source) voice over IP(or serial connection) program that focuses on encryption, however you can turn it off if you don't want it, or if you run into truble with export laws. I have ran it many times with it's 2.4Kbit codec, and it sounds much better that anything else I have ever heard over 56k modems. Since your only using 2.4kbit/s, if you are using it over bad links, it can easily resend data and have plenty of bandwith still left over.
It will run under DOS,Windows,and many types of Unix
Hey, if you enable lite mode in your user prefs, slashdot can be easily read on your calc! I want to try hooking up my ti-92(since it has a full qwerty keyboard), but ANY device that is capable of acting as a serial terminal should work fine.
Plug a modem(or the other side of the serial cable) into your Linux/Unix box and add a getty for your serial port to/etc/inittab. Then you can probably run one of the WWW browsers for TTYs(there still are a few out there), and browse away!
-As for the few that are saying calulators are a bad thing, try doing a few DCTs in your head. Then tell me they're a bad thing!
