I don't. I HATE having old textbooks. I seel them right after I am done with them because most "textbooks" are so customized to the course as to be useless. The faculty at some institutions are so set in a certain book that they don't even spend time developing labs for the students on their own.
The only thing is the hard disk in most Powerbooks and iBooks are 5400 RPM. That is too slow for capture. I capture to a tape and then edit things down. On my powerbook, I capture to a external USB drive. I am due to get another one as my existing drive is getting kind of full.
The funny thing is, in most 4 hour events, you rarely have more then 1 hour that is watchable. It's no fun watching the kids setup the stage for the next act at a school function. I only record when the kids are DOING something and start slightly before and end slightly after. I have been thinking about getting one of those cheap SD card based cams as a backup to my camcorder, and to use when the camcorder, tripod and batteries is too much to carry.
Also, it's not the shell that is insecure....it's the fact that most Windows users are still, to this day, forced to run as administrator to run some random programs that you shouldn't need Admin rights for either. Also, these same users do not know better and also whine when they have to type in a password. You can't change behavior that has been bred in by many years of use of a insecure OS that was insecure by design.
I read somewhere that they are working on a way to shut off a SRB in mid flight. Personally, I am all for the reuse of a portion of this. Plus they tear down and inspect the SRB between flights. Also, one thing that people are missing is that a capsule can have a escape tower. This could lift the astronauts enmass off of the rocket at any time. No ejection seats needed. If the SRB is sufficiently sensored or at the very least monitored, they could trigger the escape tower to ignite. Also, with a capsule, you could have burnthrough and still survive. The burn through on Challenger caused the ET to blow up. Notice BOTH SRB's, including the one that burned through snaked all over the sky after the ET and the Orbiter blew up. I think as long as highly flammable liquid rocket fuel is not near the blow through, you'd be ok.
I remember in high school a younger neighbor of mine got a GI Joe space shuttle. It was a lifting body with a rocket powered and MANNED booster stage. It was not a jet, but it was a liquid fueled space craft on it's own (well, it looked like it was). Anyway, I always thought why did they not build something like that instead of the current design? Anyway, I think the plane format has merit as soon as we figure out how to make more compact and efficient rocket engines. Launching a current Shuttle from the 747 carry is not a option since the SSME's lack tankage. If they figured out how to make engines with equivalent thrust to the SSME's without the massive fuel requirements, it could work.
The big push to the capsule format again is a good thing and let's remember one thing.....it could be the size of the Apollo capsule, but they would now have more room since modern electronics are MUCH smaller then the old technology used in Apollo. The new capsules does not mean that NASA is switching back to nixie tube displays and old style avionics. The new capsules could even be BIGGER. I thing the problem the shuttle brewed was it stagnated aerospace development because the government did not invest in new vehicles and had not since the shuttle came into use. Now with Xprize in the can(which I might add brought a TON of new ideas to the plate) and intrest in the space program building, there's reasons to go into Aerospace and new materials development with the eye on new space vehicles. As the entire NASA budget is only 2 percent of our total federal budget(they SHOULD raise this!), I personally would love to see the era of the 60's - 80's return to the Aerospace industry.
Lots of people want to download say a Linux distro on release day and I know of no Linux company that will be able to have a server that will hold up. So, they create a torrent and when millions are all trying to download it at the same time can because bit torrent speeds this up immensly. What happens later that month? What happens in 2 months? That iso isn't ALWAYS going to be in hot demand. After a while, the torrent becomes slow since there are no downloaders. It would be nice if you can have a server or cms software atuomagically change the link to the static web site once the on coming rush is done. Bit Torrent only works well when lots of people want the file. Once the rush is over, the static link works better.
You obviously have not built antennas for HF then where it's EXTREMELY easy to built a antenna that causes losses. It's not really that hard to do it on 2.4 GHz either.
ERP is used for Repeaters. I also would not be a bit surprised to see the FCC swich to ERP for all parts mostly because of invalid environmental concerns (OH my you might get brain cancer and such......NOT).
Fixed point to point (unlicensed) is restricted to 4 watts EIRP(unless things have changed since 2002 when this http://www.wi-fiplanet.com/tutorials/article.php/1 144391 was wrote. ). That would be 1 watt plus 6 dBi gain. That's is relaxed compared to Omni Directional rules. In any case, if you homebrew and antenna, you better hope whoever designed it thought about all of those things when designed. According to the same article, the maximum gain you'd likely be allowed from your antenna is about 8-9 dBi for a omni-directional. At least according to that article I linked to.
Your right about iding every 10 minutes, but CW and phoen are usually the only modes I know that you have to be aware of it. Packet usually handles this via your TNC.
IF every transmission is attacthed to YOUR BSSID you are ID'ing EVERY time you transmit a packet! You are using your CALLSIGN. I guess I forgot to mention this and that's my bad.
I know of NO malfunction of transmitting equipment that will increase ERP. If your antenna is wacked off by a overhang, your will LOSE power. If your coax is crap, you will lose power. The ONLY malfunction I can see causing a increase is a sudden surge of power and then you radio will not likely last long in this method. I GUESS parisitic metallic elements may likely increase your signal marginally and could be considered a malfunction, but mose malfunctioning radios and antennas will not increase power. It may be possible, but it's DEFINITELY not likely.
Posessing a ham license IS enough because as a licensed operator, you ARE obviously required to follow the rules else you will lose your license.
Power requirements are MORE then just the transmitter power. FCC ALWAYS uses ERP or Effective Radiated Power for measurement. It DOES NOT MATTER that you did NOT mod your AP with Sveasoft or amped up your signal if you put a cantenna on it, it MAY be ok, but it may not. Only way to tell is to measure it.
Of course there are third party antennas that will work. Otherwise, they would not be able to SELL them. The ducks Linksys makes usually do not provide ANY gain. In fact, they usually cause a power loss. If the AP you have is UNDER the required wattage, then you MAY be able to get away with a higher gain antenna.
Things DO malfunction and in those cases it usually does not INCREASE ERP. This shows you don't know anything about antennas.
That is CORRECT. You are REQUIRED to ID every 10 minutes....if it's a VOICE or CW transmission. Using your name in the Base Station ID (and not hiding it) is usually adequate. This is what I have learned at Hamvention when attending a session on a similar long distance trial. They did A LOT of research into this. I think they evencalled the local FCC office to make sur ewhat they were going to do was kosher.
ALSO, in the case of unlicensed spectrum, licensed ops usualy have the right of way. Now that does not mean you should be an idiot, but if some non-licensed individual complained about it, the FCC would tell the unlicensed party to pound sand and to move to another channel.
Good to know. Actually, I attended a very good presentation on a team who was trying to sustain a WiFi connection from somewhere near the Kings Island area, to an area near downtown Cincinnatti. Not quite as far as this, but still impressive. The Amatuer Radio community are at the forefront of hacking WiFi access points for use in Amateur Radio. Since we are licensed, we can use large parts of the existing WiFi band for doing various things. One thing that's being looked at is using WiFi for voip radios. Another is just for long distance data connections. The technology at the core, Direct Sequence Spread Spectrum has been of intrest to hams for a while now and now hams have a easy way to get a radio. Hams definitly want to take advantage of cheap wifi access points.
AMEN. I have an issue with Multisync/synce combination. Whenever appointments get over from my PDA, it screws up the time if it's not set to UTC in Evolution. The Synce developers say to try the CVS version. I would, but I cant get the friggin thing to compile. Maybe you need to have 2 CVS's....or maybe just build a friggin binary to fix it...
Granted, I DO realize that alot of the programmers working on Linux don't get paid, but there are still many that do. I am greatful for what DOES work.
BUT, most programs are available to your package manager and it's best if your not familiar with the compile process to wait until the binary is made available by your distro's repository (apt, yum....whatever). Sure, this may mean your waiting to use the new version of Scribus or whatnot, but really, is that point release always worth getting? 90 percent of the time it isn't. It's that 10 percent where you really need what is in CVS and you need it to work. Also, I hate the way some projects label things. Enlightenment 0.16 is stable. It's basically Enlightenment version 1 (or maybe 2). Enlightenment 0.17 is still a bit unstable for me to be mucking with it.
Hate to reply to myself, but the local law confiscating your cantenna and other equipment is only illegal if that podunk law enforcement officer is just taking it with out evidence of you using it for illegal activities (hacking wifi networks). If you use it to leech bandwidth from your neighbor, then the local law CAN and WILL arrest you. Law enforcement usually has no idea what is illegal or not antenna wise so they would likely pass info on to the FCC and then the FCC can decide if a enforcement action has to occur.
Depends. If your a LICENSED Amateur Radio Operator, cantennas and this dish used for the record are legal. Anyone else, like 90 percent of us who use WiFI, it's not legal. Only the antenna that comes with your equipment or is designed for use with that equipment (like DESIGNED to work with it)can guarantee that you stay udner the FCC's regulated ERP rules. Will the FCC do a enforcement action? Not likely. Does podunk Police officers have the right to confiscate your equipment? NO. In the US, the FCC is the ruling body responsible for regulating RF. The local law has no jurisdiction on it. It would be called a Federal Premption.
OK....so that tells me they are DUE for a new one. You call the new 49G+ a redesign? Well, partially. It looks, to me, to be a interim design until they have time to design one around something other then a saturn. The new ones run on a StrongARM and the emulate the Saturn processor. They are, in every way, better then the old 49G+. No where NEAR the build quality but WAY better then the last one they had before their break.
Our Walmart now has a iPod section. For the moment, they have BOTH versions. HP and Apple iPods. Sure, Walmart already had a in with Walmart and Apple did not. I think part of this was so Apple could see how to get into Walmart. Either that, or Walmart went to Apple upon rumors of the HP stopping the deal and now that is why the APPLE iPod is now on the shelf at my local Walmart.
More and more people use UNIX or Linux every day and don't know it. One example would be the Tivo. There are many many more examples of Linux being used in the embedded space. This is proof that UNIX or Linux CAN be made user friendly. There will ALWAYS be the Debian's, the Gentoo's and others for the real top end geeks, but lots of people CAN be comfortable with Ubuntu, Linspire and others. The sheer customizability of Linux is how this all can happen. Managed code can be run on top of UNIX and users will have to type a password or do some biometric security to install certain items. The modulairty of UNIX saves us from the hell of a integrated Windows. That does not mean that software will perform bad or every program will have a different interface...one CAN have a system that is LESS integrated, yet the componets work well. Just look at pipes, grep and regular expressions in UNIX. Things like these allow you to make it seem like desparate programs that were made by different people with different ideas can all work together. Small components working together hand in hand instead of giant monolithic api's will save the day.
I hae no idea why Congress thinks this thing will svae oil. Back when DST was invented, it was understandable. Now, we're different. Now we have people who work at any time during the span of 24 hours. We have 24 hour stores and there's more activity at night now then ever before. I bet that the existing DST does nothing to save oil now at this point. Sure, it's nice to have those extra daylight hours and what not but is it worth causing untold number of devices (regular desktops and servers will be fine, but it's the embedded stuff that is the problem now). Changing it now would not make a difference in oil usage.
