Our foreign policy is similar to the policy of that the British used for centuries to keep countries in line.
China's economy is dependent on making cheap shit for the USA. When conflict arises with China (which will happen), the chinese will get a wakeup call when they discover the our navy (the only high-seas fleet on earth) will interdict all of their exports/imports.
The source of trouble for the US in 50 years will be Asia but Europe.
The US currently dominates outer space (at least earth orbit) The recon satellietes that the Air Force and CIA operate allow us to observe our friends and enemies from afar, day or night. These 'birds' are impervious to any weapon currently deployed.
A little less than a century ago a similar situation existed over France. British, French and German recon planes circled over the battlefield of the western front, directing artillery fire and providing intelligence about troops movements and such.
The response to these recon planes was... fighter planes to chase them off! Then someone realized that you could shoot stuff on the ground with an airplane, so the bomber was born.
When the US and China fight in 20 years, the same thing will happen with spacecraft.
Before you laugh at this, think about the nature of war. What is more valuable, 50,000 soldiers standing in the wrong place or 5,000 soldiers who know exactly where the targets are, thanks to the 'eye in the sky'?
What we need is a packaging system that can correctly detect whether or not dependent packages are installed without having to have a database. The package manager needs to be aware of the differences between platforms.
The problem is, inevitably, the database will get out of sync the moment you have to compile something from source because no.deb or.rpm file is available right then, or because you have a local patch to fix a bug you need which isn't important enough for enough other people for the author(s) to fix right now (or maybe is to complicated for them to figure out how to roll it back in without breaking things for other people that you don't happen to need to worry about). Even buying software that uses install shield or some other installer will mess up everything.
Once the database is out of sync, then new problems come up, and those are easily fixed by forcing an install or installing from source, and then it just gets worse.
Without a database, it would mean the installer would have to have a way to detect whether the dependent thing is installed or not, and in the correct version. I won't say that would be easy, but it is what would be needed. Until then, based on my past experiences with Redhat's RPM, I won't at all be interested in a fancy packaging system.
Heavy traffic combined with poor software.
Maybe if they used a real relation database (ie. NOT mysql) they could replicate the database in real time, and maybe be able to handle their traffic, and keep articles on line for more than two months.
The real amazing thing is the lack of stories about subjects other than CS. Aparently, teachers of English and History or Science have had little impact on the Slashdot population.
Maybe this explains why Slashdot is such a dysfunctional 'community'? There is nothing worse (or more pathetic) than a bunch of CS geeks vying for attention on a messageboard.
I understand that you are a complete guru/Linux god, and are incapable of fucking up configuration of your box. If you want to host your own DNS and mail, then use a service that allows you to do that.
Many professional sysadmins accidently leave open smtp relays on the internet. So, to put it mildly, home users cannot be trusted with providing such a service.
It's amazing that Slashdot posters agree that porn should not be censored from public libraries, yet censoring entire network blocks in the name of "eliminating spam" is ok.
I propose that in accordance to Slashdot logic we ban all library ip's at the backbone router level to stop spam and other forms of network abuse. I see no reason to subsidize via taxation the porn habits of perverts or the internet purchases of consumers.
Spam is scummy, but cutting off blocks of the internet from email as championed by MAPS/ORBS/etc will accomplish nothing but restrict OUR rights to communicate and get the government involved in the Internet even further.
Taking away our rights to speak and be heard in order to 'protect' us from spam is a complete violation of the first amendment.
While the acts of spammers violate AUP's of internet providers and cost us money; the acts of anti-spammers and organizations who use their service violate our rights and are the real criminals.
I love it when people who have no clue what they are talking about try to address complex technical issues on slashdot. The whole DBA team in my office almost died laughing at this post.
Here's a few highlights:
"Get larger, not necessarily as fast drives for your primary partitions. These can and should be on very large RAID/5 partitions"
RAID/5 + Databases = Bad data. RAID-5 reduces write performance by about 30% (and uses more cpu), and does not protect your data from controller failure (or for more than one disk failure per volume).
All data chunks need to be on simple volumes or RAID 0+1. This allows you to have up 50% of the disks in a volume fail without a loss of data. If you use DMP on the fibre channel array, you'll also get load balancing.
"Get larger, not necessarily as fast drives for your primary partitions. These can and should be on very large RAID/5 partitions."
In a perfect world, you would have more fast disks. In the past 2 years disk capacity has increased 10x while speeds have increased barely 2x. Multi-terabyte databases need to be on multiple, switched fibre channel arrays with the smallest (like 18GB) disks possible. This is expensive, but if you have 2TB of data online, you should have the money to buy a real solution.
"Get a bunch of smaller, but at least 10,000 RPM drives for your index storage. They should be on quite a few different hardware RAID adapters, and you should be using RAID/0 for them. For this, you don't care about losing a drive. The worst that can happen is reduced performance while you rebuild an index, you'll never lose any data."
This one is great. Any DBA who consideres it to be no big deal to lose a whole dbspace worth of detached indexes need to go back to Burger King. I'm sure everyone will be REAL happy when the database is in single-user mode while you 'just rebuild' all of your indexes. (All of your indexes were lost, since you have no mirroring, remember?)
Who needs RAID or a relational database? Just read the linux clustering HOWTO and apt-get yourself an enterprise database. MySQL is a better and faster database than anything else out there. Who needs online backup or transactions anyway.
Besides, since it is open source I can just skip lunch and write a perl script to fix all of my corrupted data!
The so-called "Open Source Community" has a very short memory.
Go to the library and look in the archives for some old business magazines with Netscape profiles. Netscape's numero uno objective was to expand it's role and begin to take over the desktop. Their original vision was to create a platform-independent desktop that would allow other companies (like Sun and Oracle) to pull marketshare from Microsoft.
Why do you think McNealy of Sun and Ellison of Oracle are so anti-Microsoft? The network computer is Larry Ellison's stillborn baby which may have survived if Netscape made it. Sun also wanted to roll out thin-client computers on a large scale so it could push out more E3000's to run them.
The ironic thing is that the 'Open Source' zealots of Slashdot who complain endlessly about the subvertive influence of 'evil' organizations like Microsoft, Intel and FBI. Never even noticed that swallowed the Netscape sham hook, line and sinker.
Even more ironic is that many 'Open Source' developers DONATED their time to create AOL 7.0 aka Mozilla 6 for the ultimate 'evil' corporate conglomorate: AOL-TimeWarner.
Trays of mail presorted mail eliminate any sorting from being done in the originating post office, and eliminates at least two sorting runs in the distribution centers.
Since you are an idiot, I'm sure that the thought that it is cheaper to handle a pallet of bundled, presorted by zip+4 magazines never crossed your mind?
Did you know that in large post offices the special magazine rates lowered the time to sort mail into delivery routes by 8%? That 8% adds up to millions of dollars, and is a good example of how the post office as a whole has cut costs and made itself self-sufficient.
I agree that performance-wise you will the differences between Solaris and Linux are less apparent -- but why would you chose an operating system which is not endorsed by the vendor when the vendor OS is excellent and well supported? If you encounter any subtle hardware issues, you will have to spend lots of time on the phone convincing the support engineers that Linux isn't the problem. I don't have that time.
Plus, Solaris 8 licenses are free (as in beer), so that is not an issue. What is incentive to use Linux? I could give a shit about software licensing philosophy.
As far as my preference vis a vis Solaris and Linux goes, it's hard to put a handle on. Serial consoles rock, and I am more accostomed to the Solaris/devices,/dev and the quirks that Sun threw in for configuration files and such. As you mentioned, linux SMP performance sucks, I believe that even SCO (ick) is better in large systems.
Linux is perfect for many applications; we've moved report modules, DNS, email, etc. from NT and Solaris to Linux with stellar results. However, in some medium database apps, Solaris rocked the house, especially when under heavy i/o load.
What you are describing is an effort to preserve the company in the event of a government bailout.
PG&E is lending money to itself because nobody else will. Nobody has ever gotten rich by giving products away and loaning money to themselves.
The only people getting rich are the power generators, on the backs of California taxpayers.
Instead of blaming a failing business for attempting to preserve itself, maybe California voters should blame their idiot shortsited State Assembly for mucking with the utility regulations.
I hate to be rude, but you should really turn off your tv and pull your head out of your asshole. Reading something other than slashdot headlines might help too.
Do you think that the power companies want to buy power on a contingency basis from independent generators? Do they want to run themselves into the ground? Are the people running these companies retarded? No.
The 'deregulation' regulations prohibit power companies from entering into long term purchase agreements with generators. This was meant to 'even the field'.
Unfortunately, you can't even a field by digging a hole. Since power distributors have to buy small lots of power very close to the time that they need to use the power the price goes up.
Have you ever purchased film for a camera? Ever notice that a single roll of film at the airport costs more than a 10-pack at Costco or Sam's club? California power companies are buying their film at the airport.
I realize that slashdot is a Linux site, but why would you want to run something other than Solaris on a MODERN sun box?
Solaris is a very good operating system, and I have found it more suitable for the databases and programs that I work with. (No, I am not interested in Postgre or mySQL, don't flame please)

I don't know about their dial-up service, but Qwest frame-relay sucks big time. Frequent outages and inept engineers are the biggest features.
In solaris 8, bash is shipped in a supplement cd, along with kde, gnome and other freeware utilities.
I do not believe that sun 'officially' supports it.
Heavy traffic combined with poor software. Maybe if they used a real relation database (ie. NOT mysql) they could replicate the database in real time, and maybe be able to handle their traffic, and keep articles on line for more than two months.
Qmail does not disallow relaying by default.
I know how you feel--
My network class spent a month on the ALOHA protocol. The rest of the class consisted of the professor bitching about his cable modem.

I would also like to add that when you know management is going to pick at your proposals, make sure to pad your numbers.
I try to propose for hardware at least 25% more powerful than what I need, and add 50% time for mid-sized projects.
If it takes two weeks, say you need three. If you need a 2 way Sun E3500, ask for a couple more cpu's.
Your nothing but a troll.
