Seems to me IBM, Sun, and Linux make high profile, juicy targets for crackers. They don't get rooted because their servers run as unprivledged users, ordinary users don't have root privledges when they login, ordinary users can't write to system directories. Micro$soft ignores all these simple security precautions, so when clueless droolers like you open up a viagra ad they wreck their machine. M$ monoculture justifies this? Think.
so exactly how does any of that refute what I said about Active Directory?
How can I be more blunt? AD is a blatant ripoff of LDAP. It is an incompatable extension. They did the same thing with Kerberos. Standard Micro$oft. They would have done the same thing with the BSD network stack if it weren't for the antitrust case.
If the words Open LDAP trickle out of your zealot lips, you'll basically prove the point you have no idea what you are talking about and are just spreading FUD.
In regard to LDAP: If you are content to let Micro$oft hijack good ideas, butcher them beyond all recognition, then pretend they were theirs in the first place, there is little I can do to make you rational. Perhaps you have been sodomized by Bill Gates for so long you are no longer able to resist. After 15 years of Micro$oft the enterprise is a malware infested, virus ridden wreck!
This has *nothing* to do with Windows being teh suq. Rather, this has everything to do with the previous admin not knowing what he was doing.
What else would a mindless Windoze fanboy say? It must be the stupid admin. It is drones like you we can blame for the lousy state of enterprise computing.
Which, is why I believe employeer-provided health insurance is evil. I don't believe in state-provided insurance either for all the inefficiences that come with socialism. I do advocate for personal health insurance, where you are personally responsible for each dollar spent for fees and it has no ties to your employer or any other group that would use it to coerce you into acting against your own best interests.
This is the smartest thing I've read on this forum in a long time. You're right. Why should purchasing personal health insurance be any more difficult than buying car insurance? Why tolerate an employer having this kind of leverage in your life? The idea of calling a necessity like health insurance a benefit is misleading. It is really part of a calculated scheme to shackle workers with families to their jobs to minimize the free flow of labor.
Actually, it hasn't proved anything, and your statement underlies a lack of statistical understanding. A 1:100 chance of failure does not indicate that out of every 100 attempts, there will be 1 failure.
My point is that despite Dr. Feynman's misgivings the redesigned SRBs are operating within margins, as are the SSME's. I do understand the concept of independant trials. I also understand that the success rate of the SRBs and the margins by which they operate say something about their reliablity. You might grasp elementary statistics, but you do not seem to be able to apply them intelligently.
Having 1 thruster active with directional nossels is safer than two either side as per the shuttle design. As if one booster/rocket fails on the shuttle you would lose directional control.
There is nothing safe about an unplanned shutdown at hypersonic speeds. With two SRB's is it not likely either will stop burning until they have consumed all of their fuel anyway. SRBs are a very useful method for hefting a large rocket out of the atmosphere where its high Isp engines can do the most good.
Finally, MS has understood that a powerful shell language is necessary for a modern operating system.
True. But as a long time Unix command line guy, I admire the way Windoze monkeys are able to mouse around their screens so quickly. I think they develop this skill so they can cram in as much work as possible in before their machine 'locks up'.
As much of a fan of Mr. Feynman as I am I think he has been proven wrong here.
On the solid rocket booster: A more reasonable figure for [reliability of] the mature rockets might be 1 in 50. With special care in the selection of parts and in inspection, a figure of below 1 in 100 might be achieved but 1 in 1,000 is probably not attainable with today's technology.
Since the Challenger disaster, the space shuttle SRB has flown 176 times in a row now without any engineering or flight anomolies. The space shuttle main engine has had 1 in-flight shutdown and two pad aborts in the entire history of the program! that is almost 115 flights. That is pretty amazing. The Saturn V had more in flight shutdowns than that in just a dozen flights. The shuttle design may be bad, but many components are outstanding and should be salvaged. Mr. Feynman's estimates are not holding up.
CO2 is recycled by erosion. My point is that over geologic time volcanic activity will slow down as Earth's radiogenic heat supply vanishes. This will reduce the amount of CO2 released by outgasing. The erosional component is still there, but that process releases much less CO2 then is abosorbed by calcite production. Carbon does not predominate at great depth in the ocean. What sits down there are called anoxic pelagic clays. What ends up on the ocean floor is not important as a carbon sink. The oldest oceanic crust is only 125My old.
I used to work at Hughes Space and Communications (now Boeing). All satellites used to undergo a vibration test on a giant paint shaker-like device. Ostensibly it was to verify that the satellite could handle vibrations during launch. The joke was on the factory floor that it was really to clean out screwdrivers and ham sandwiches left behind by the technicians who assembled the satellite. They actually put a white sheet under the rig to catch any parts that fell off.
Carbon dioxide is being scubbed from the atmosphere all of the time by the formation of limestone (calcium carbonate). No need to put it anywhere. In fact some scientists believe that the process of removal of CO2 from the atmosphere will eventually cause photosynthesis to cease and end life on earth. Granted, this process works over the very long term (1 Gyr). Volcanic outgasing and burning of hydrocarbons still major sources of CO2 in the short term.
"When you get a reply, it's 70% sure that you'll get the money," Samuel said.
I find that replying to scam email can make for great sport. Just be careful to use an anonymous account and you can play with these guys for days. I can just imagine the guy on the other end salivating when I ask for information on where I can wire my $1000.
What I am hoping is that someone with influence in 'the enterprise' like Booch, or Yourdon (you know the type) will rediscover that programming with side effects is not so nice. I know Lisp would be a hard sell because its syntax has such a bad reputation. But one can always hope.
You make a good point. Fortunately PHP, Python, and Ruby are simplistic enough where specialization require a huge investiment in time like Java or C++. I think the hacking world is pretty saturated with languages. It started with Java in 1995, Perl, ASP, PHP, Python, and really ended with Ruby a few years ago. None of these languages has really advanced the state of the art. I am still waiting for Lisp to become fashionable again. We'd all be better off.
It's the non-standard nature of the directory tree that gets on my nerves./bin,/usr/bin,/usr/share/bin,/usr/local/bin,/usr/local/share/bin... Aargh!
I have not seen/usr/share/bin,/usr/local/share/bin. These are grotesque./usr/local makes an inconvenient and ugly garbage dump IMHO, just because of the length of the name. I much prefer/opt/. You can get long paths this way, but tentative and potentially disruptive packages stay segregated. My Gentoo machine doesn't have any of this confusion. You might complain that/usr/bin is overused. But the rc infrastructure is the best I've seen. Lightyears better than RedHat. I think because Gentoo drops all pretense of trying to support graphical system administration they have done a great job making text base configuration as good as it can be.
The amount of oil predicted to be saved over the several weeks involved in the time shift, is less than all of the oil the USA uses in a SINGLE day.
Sounds like about 5% to me. Your statement supports the opposite view.
There are going to be millions of VCRs and other hard coded devices designed to change to the old DST law, meaning many will auto-adjust to the wrong time.
A the US should waste millions of barrels of oil because some programmers chose a crude hack to adjust time? Also, VCR use is in rapid decline.
Airlines and other businesses that depend on time are going to have to reprogram many things, and thus this will impact their bottom line. [Is this a good thing when so many are going bankrupt?]
The airlines might have taken some of the 10's of billions the feds gave them after 9/11 to do this. Your point is adsurd.
If we legislated that vehicles must achieve twice the MPG rating they have today, then we'd use approximately half as much oil. That's a savings of 50% every single day. [Maybe if George thought about that every...single...day, just like he thinks about the Iraq War every..single..Day, then we wouldn't have to put up and deal with this stupid time change!]
Great idea. In mandating hybrids the average cost of a car doubles, meaning large segments of the population can't afford to drive. What George Bush really needs to do is levy a large tribute in oil from Iraq in payment for freeing their country. Say 25% of their production. GDub rocks!
The hydrogen economy is an exciting prospect, but where will the hydrogen come from? Not natural to be sure. The process creates CO2 emissions! I've always thought the federal government might fund a huge nuclear plant to for trial H2O => H2 + O2 conversion. How much nuclear power would it take to establish the hydrogen economy?
For the last 10 years or more we've been saying there is "most likely" water in the form of ice at the poles. We have yet to land a probe, drill out a sample and test it. That'd be great science wouldn't it?
There is no doubt that there is interest building to due this soon. Is is great science? I'd say it is a second order result. It is already highly likely given all of the indirect evidence. I think your idea of finding high concentration metallic meteoric deposits is at least as interesting.
Because it was considered by just about every scientist alive at the time of Apollo that there was absolutely no scientific value in sending a man to the Moon. Not just British scientists but Americian scientists too held this opinion. Many still hold this opinion today.
This is such a sad statement, and inaccurate. The Apollo missions were incredibly productive. The first geological exploration another world? 6 missions exploring amazingly diverse sites. Apollo contibuted greatly geomorphology, volcanology, geochemistry, isotope studies, remnote sensing, mapping... The Apollo mission reports are still available. Read them. I doubt you will feel the same way. As a former planetary geologist I can assure you that that opinion is not widespread in that community.
If you say this about Apollo, what do you think about the pointless research on the even more expensive space station?
Despite my misgivings about the inappropriate and trivial use of technology in todays public schools, I think the biggest crime is their builtin inequity. Sure, if you live in an afluent neighborhood where property tax revenues are high, things are relatively well. The reverse is true of this formula for poor neighborhoods. Under the umbrella of 'public schools' generations of poor Americans have no real path to better themselves. Their American dream is a pure hoax. I was fortunate enough to attend catholic grade school and private high school where expectations were high, and computers slow or non-existant.
The US knows this too, and so is getting back in the game to keep dominance over China.
Agreed. With the many countries also showing interest in the moon, it is better to be living and working there then to be surprised by an upstart country. It is certainly not in the US interest to cede the moon to Russia or China. The political forces at work here are no different that those that drove the development of the new world.
The best way to build your population up intellectually is through information.
I think this is a common misconception. Widespread internet service is a good thing, but it does little but distract in today's educational system. The hard work of education: mathematics and literacy, require a pencil and paper, time, and a decent instructor. Sadly even these necessities escape many students in our horrendous public educational sytem.
