When you get on the train, you slide your ticket through a reader, and are instructed which car to proceed to.
I assume you're on about compulsary seat reservations then? I've got on some trains in the UK with a first stop 2 hours away (about 220 miles) where people were left on the platform due to the train being so busy. Commuter services can be much worse. There's no way you can pass through a chocked 12 car train, even without luggage. You'd have to give more space over to gangways, reducing seating capacity even more, which increases the price.
Bikes are nice but they are an option only for people who live relatively close to their working place.
I live 45 miles from my work, but a bike is integral to my commute. The first 2 miles are bike, which I then fold, then get on the train. Arrive at terminal in the centre of a major city 40 miles away (30 minutes). The final 5 miles are also by bike.
Total time one hour. If it's a good traffic day I can do it in 1h15 by car.
Weather can also be an issue. Here in Finland it can be a real pain cycling to work through half molten snow.
I went to Canada earlier in the year (admittadly May), and the French alps at christmas. lots of snow, but I didn't notice any on the roads. Don't you have Mr Plow?
Also, trains can carry at least hundreds of people at the same time. Also, a crowd of hundreds of japanese riding their bikes to work would look funny:)
This is a valid point. Unless lanes are wide enough to allow easy overtaking of slower bikes, it's a right pain. Cyclists vary massively in their speeds. The 3 cyclists in my office average 15-20mph (higher than average taxi speeds, which are the fastest form of road transport in London), and will take a longer route to avoid traffic lights/stop signs/give ways etc.
Most cyclists in London pootle along at 5-10mph, which is a right pain if you don't have the room to overtake.
most of the items that git 'claims' to be better on is something IDE plugins fix
Funny, but I've never got the IDE plugin for *any* version control system working well. Since I always have at least one command window open, typing "git commit -a" is faster and easier than locating the corresponding menu, clicking on it, and praying that it will do exactly what I want.
Disclaimer: Of course, this doesn't mean I don't use the many other functions that work better on an IDE than in a text command. I can use vi occasionally for a quick edit, but development of a large code base is much easier and quicker on a good IDE. It's just that version control is quicker on the command line.
Vim is my IDE -- Ctrl-]/Ctrl-T to jump around tags, F2 gives me a list of files/functions, F5 compiles/runs, F12 (in perl mode) syntax checks the file, shift-F5 svn commit, F11 maps to a help function, etc
Both people arguing that the bridge is "free" are idiots. There is no "hidden value." The cost of the bridge was, simply put, the labor of the workers who built it and the cost of their raw materials. That's the price tag. The value it produces is it's return to local economy in the amount of gas the average commuter saves as a result of the bridge being in place.
So what's the value of the Sun? Nobody built it, you can't sell it, you can't buy it, yet it's the most valuable thing in the solar system. Our species can survive without anything, even the Earth, except the Sun.
But, remember Harry Kim got to be Captain of the Rhode Island in the possible future timeline in the last episode of VOY... Adm. Janeway from the future goes back to the "present" to help get the ship home earlier, Capt. Kim helps her fight off some Klingons, etc. But now that Voyager got home earlier, things will be different from that future. Who knows maybe Harry will become Captain sooner?
Here's how "free" government, socialized healthcare works:
- I smoke. I destroy my lungs. - Thanks to the miracle of technology, I can get new lungs from a deceased donor. - This procedure costs ~$100,000 per lung. - Who pays the bill?
In the UK It's the government. Taxation on Smoking raises more than the cost of medical care of smoking.
And the 90% of Americans that don't earn anywhere near $100K a year -- even if they saved every penny they earnt. Average wage in the U.S. is about $45k -- it was under $40k in 2006 http://www.ssa.gov/OACT/COLA/AWI.html
IMHO the only people who should receive handouts are the handicapped, or children. Able-bodied people should pay their own bills with their OWN money, not raid their neighbors' wallets.
Why should handicapped get handouts? Why should children get anything for free?
Seriously, I know this is Slashdot, but when was the last time you used a Windows PC. I've been using XP for years and it has never crashed. Never seen a BSoD, never froze, software has never stopped working. Completely smooth. Stop promoting the instability stereotype. Windows ME was years ago, times have changed.
"Windows" (specifically outlook.exe) hasn't crashed on me for 22 hours, which isn't bad. All it runs is outlook and google desktop though. Still, our corporation runs on Office 2002 and IE6, so perhaps Vista, Office 08 and IE7 are better. My day-to-day machine is linux, and also has it's problems 1GB of memory isn't good enough for firefox some days, and then it starts swapping, which is a right pain.
Set up dependencies is a must, use notification_delay wisely, and only send out emails or other 'push' notifications for problems that have to have immediate attention. I like to take the approach of monitoring everything that is important but only send emails out for problems that really truly require immediate attention from on-call staff.
We don't send emails. My corp has several nagios installations arround the place, our own in a 200 hosts/800 service one, another departments has a larger installation of 500 hosts.
We don't send any emails, people ignore emails. Instead, we present a list of service problems in a heigherarchical way (a custom webpage that reads the current status). This allows the enginneers to see what's affected by a problem. When no services are affected, they can tackle the normal service problems (i.e. 3 of 50 nodes in a process cluster aren't running)
Each service page has links into our wiki and logging system to search for problems, and find out how to enter them
We don't send emails though. We trap "one-off" alerts by setting an alert to critical for 15 minutes, then automatically greening it.
The point of the GPL is to make source code available to end users, as per Stallman's definition of software freedom. Without copyright, GPL code authors would have no way of enforcing source code availability when others make changes to it. Microsoft could sell a closed-source version of Windows Server running on the Linux kernel, and there's nothing Linus could do to stop them. The viral, protective nature of the GPL would be gone.
But without copyright why would Microsoft sell windows server -- or rather why would anyone buy it?
Not to mention, all the US debt is in dollars... As dollar loses value, the debt gets smaller. Nobody wants that, it'd be crap for almost everybody globally
Not America though. Revert to an isolationist society and emerge in 50 years to take on China and the rest, rather than thrashing and dying for 100 years.
Another reason to keep devices off is so you're concentrating on the announcements that are made, if something goes wrong and everyone needs to get out.
Stick a few zero's on the end of every dollar bill, and you're sorted.
Sure, you've devauled your currency, but suddenly all this ridiculous mortgages are realistic, and the planet-killing baby-boomer generation get their comeuppance.
You should see our 2nd line people, if they can use it, anyone can. 1) Big red problem appears on page 2) They click the link to the logging system which does an asset-based search showing recent problems. 3) They click the link to the wiki page for that host, which hints at how to fix it. 4) Red thing goes away
There's a difference between *use* and *configure*. Nagios is the easiest monitoring system we've ever used in our department. It's pretty easy to configure too when you know what you're doing (one config file per device host, one directory per logical division of devices, one perl script to splat out the devices, one subversion repository to version track everything)
I hope they changed it in a major way, because last time I tried to use it I was forced to dig through configuration files and learn syntax just to get the thing to see if some server was responding to pings.
So? What use is a monitoring program that tells you that. If you want to do decent monitoring, you want to monitor the systems, not the devices those systems happen to run.
It's a steep learning curve, but have you ever configured apache from scratch? Let alone bind or sendmail.
So Nagios is hard to set up? Probably, you can't go from zero to running in 5 minutes. It's a steep learning curve, but if the initial investment of a book (I used building a monitoring environment with nagios) and a few hours, you shouldn't be monitoring things. You won't do it correctly, you may as well throw some cron jobs together.
The first step in monitoring is working out what you want to monitor. The second step is working out what you really want to monitor. The third step is working out how you want to display problems. When you have 60 people in support working on a 6 shift 24/7 pattern, you can't expect emails to be any use. "Service problems" in nagios is fine, but there's a lot of issues that 2nd line don't need to know about -- solaris security patches on an intranet for example, can wait until the 9-5 admins get in.
Nagios is painfully easy to administer, if you set it up right. Once you know what you're doing (or even know enough to be dangerous, like myself), you can deploy a new nagios installation in about 20 minutes, add a new device that follows existing rules (new web server for example) in under 5 minutes, and a new device with new plugins in half an hour.
Nagios then grows organically. When something strange and new breaks we cobble a plugin together,
Configuration is in plain text files, one for each device on the network. I have these as an subversion working copy, which gives me the ability to track changes and easily roll back any configuration problems.
We have dozens of weird bespoke plugins, one uses WWW:Mechanize and Perl to run through a workflow on a specifc webpage, another looks at the rate of change of growth of a jboss logfile, and the proportion of stack traces, one logs into a remote machine and checks jumbo pings are working through the network.
We find nagios essential to monitor the service we provide. I don't particularly care if the server an oracle database runs on is pingable, I care if I can log in and run "select 1 from dual" (or usually something more application specific).
The small system we monitor is made up of about 800 services over 190 devices.

Redundancy... You keep using that word. I do not think it means what you think it means.
RAID 0, psudo-ironically, is not redundant at all. RAID 1, often called mirroring, are the arrays that are redundant.
The R iin raid 0 stands for "Risky"

Nope, Firefox wins by not running it.

Apache, BIND, and Sendmail are not easy to configure. If someone were hyping their "ease of use" on here, I would criticize them, as well.
Yet all three are used by your grandma every day, they are very easy to use. Easy to maintain too.
Is it extensible?
Yes, what can't you monitor with nagios?
Is it easy to use?
