So a lighting strike will take out both? You will also find ground loop problems and while ethernet is only supposed to work at about 110 meters, it will work to about double that before it starts not working and you may need to force the network into 10 or 100 mb mode.
There are several major reasons for backup:
1) computer/drive/house is destroyed
2) files were accidently deleted
3) historic archive
For #1 you have to find a way to restore onto new hardware which might have problems if you don't have the crypto keys off site too.
For #2 a local drive is the best and most automatic but it has to be able to store several versions of files (why didn't Linux get the VMS file preservation option?)
For #3 the best option is clone the hard drive every few months/years. Or better yet, remove old drive and install a new one and restore your data so you can check your data is still intact.
I tend to use backup servers which use rsync and linked files to allow several versions and deal with some data deduplication. About once a week I copy that data set to another disk and then get that off site. The result is I can restore screwups in about 5 minutes and if the place burns down, I am out out a week of data. Sicne the disks keep getting bigger, I also have backups from years ago should the tax man want to know about something specific 5 years ago if the paper records were to be unreadable. My typical backup server build is a freebsd box booting off a flash stick card and then lots of disk. The result is I only need a copy of the flash stick and and a disk and any generic PC to restore the data.
The employees are out there but they cannot work for chinese slave labor wages, nor do they want that lifestyle.
11 months ago I finished my Commercial Pilots License - I haven't been able to find any work at all since completing it. That was the last time I touched a plane.
The same problem exists. People are expected to splash $100k AUD on their license, then work for ~$25k a year. Not to mention get themselves to jobs on their own dime etc... I hear the same lines "There is a massive pilots shortage!!" - which is absolute bullshit. We just have to take other jobs to pay off the loans etc we took for our training.
It just about gutted my career - but this is the world we live in. Now I'm only casually employed - and making about the same amount as I would as a pilot - while working only a handful of hours.
The way to get the most performance out of iptables is to make each chain as small as possible.
Thats sorta the problem. Even lowend Cisco devices will handle quite lengthy ACL tables without any performance degredation.
No, No they don't. If you look at the packet-per-second performance you get when you put even some basic rules in there, you'll be surprised. Some systems have their PPS rate halved by this...
each adapter gets a configuration attached for starters, then things go from there (VLANs, ACLs, etc.)
iptables -N eth0-in
iptables -N eth0-out
iptables -A FORWARD -i eth0 -j eth0-in
iptables -A FORWARD -o eth0 -j eth0-out
Then create all the rules you need in the specified chain.
The way to get the most performance out of iptables is to make each chain as small as possible. This can quite easily be split up into logical lists for what you actually do - ie:
iptables -N 10.1.1.1
iptables -N 10.1.1.2
iptables -N 10.1.1.3
iptables -A FORWARD -i eth0 -d 10.1.1.1 -j 10.1.1.1
iptables -A FORWARD -i eth0 -d 10.1.1.2 -j 10.1.1.2
iptables -A FORWARD -i eth0 -d 10.1.1.3 -j 10.1.1.3
This way, you can easily branch out and skip a fuckton of rules that will never apply to the packet that is being processed. Usually, you can bring each chain to less than 6 rules. Less rules == less overhead == more performance.
My problem was I was thinking of trimming as an extra thing I had to do - really, it means you have less to do.
The best advice I have ever been given in flying is this: Unload yourself.
What does this mean? Ok, power on, take off roll, reach takeoff safety speed (usually 1.5x stall), rotate, airborne, set your climb attitude. Next thing, trim. With a bit of practice, about 20 seconds after liftoff, you will be trimmed for the climb - this means you can take your hands off the controls and you'll continue to climb at your (usually) 500ft/min. Your speed will be stable, your climb rate will be stable, and you'll keep climbing until you either get disturbed by a gust of wind etc or you change the controls.
Take this time now that you can fly with hands off to glance at your engine instruments - that the RPM is what you expect it to be, oil temps and pressure is ok, airspeed is what you expect, then check your performance again (attitude, power etc). This can all be done within 45 seconds after liftoff. Now you do what any VFR pilot does best - look outside. As you're not struggling to keep the aircraft under control, you can observe what is going on outside. Looking for traffic, obstacles, making sure what you see outside matches the instruments (ie you're climbing, going fast enough etc).
Coming up to your assigned / desired altitude, use the yolk to bring the nose down, power to cruise, trim, trim, trim. Usually up to about 1/2 - 3/4 of a turn on the trim wheel and you're almost able to fly hands off again in seconds.
A good exercise here - trim for the climb, then don't touch the yolk again until you're on final to land. Use the trim for your attitude and rudder for turning. Do the entire circuit using only trim, rudder and throttle. As you would have been taught, the secondary action of yaw is roll - so you'll find you actually start to bank while only using the rudder. It gets tricky - and you'll be all over the place while first trying this - but it is great for learning the relationship as to what you're doing affecting the aircraft.
Anyhow - this isn't flight training 101 on slashdot, but learning to fly has been a highlight of my life - and I'm always happy to share things with people. Feel free to email me if you want to discuss more random things
I thought the whole point of those big bright landing landing lights was to illuminate the ground when you're near touch down (and for taxi/takeoff). Runway markers may may it easy to see the runway from afar, but aren't going to be as useful for an untrained pilot to see how fast the plane is approaching the ground since a few fast moving dots of light streaming by aren't the same as a broadly lit surface).
Heh - the 'bright light' called a landing light in a C172 is almost as bright as a single car headlight (if you're lucky, like the high beam). It does sweet fuck all to illuminate the runway. If you're waiting to see the runway via the landing light before you flare, you're going to have a bad time - and probably crater. Larger aircraft have much brighter lights, but the effect is still the same.
Night landings are hard. There are no floodlit runways that I know of in existence. The only form of reference you have is the shape of the lights. There are very few clues of your height or speed by looking outside at night. Night flying kills many - as it is VERY easy to fly straight into the ground because you can't see it - this danger is magnified even more when you are on approach to an airfield - especially if it is one with a 'black hole effect'.
During my night flying assessment, I was required to land at an airport 'void of artificial lighting' - ie only runway lights. As you fly towards the airport, imagine a completely black area with two rows of lights. That is all you have. If you're lucky and there is a full moon, you may be able to make out the ground. I'd say it is one of the hardest things I have ever had to do.
(I am a student pilot, and I fly a Cessna 172)
I'm a commercial pilot (who is currently unemployed) - however operating the radio is part of my pre-flight briefing with anyone in the right seat in any G/A aircraft. In this briefing, I also go through what I'll do if we have a radio failure or comms problems - as part of this includes them using the radio (if required). Most people are very attentive - and its with this exact reason in mind - if anything incapacitates me, the least I can do for passenger safety is to get them to talk to someone who can help.
If the person in the right seat is a bit of a fan about flying, I'll teach them a bit about basic flight controls during the flight as well. Most people see if as a bit of fun and enjoy it - but there is a serious reason behind the scenes... The best way to be prepared in aviation is to think ahead.
For less experienced pilots, this is why we always aim to trim an aircraft for the correct attitude and performance as early as possible. The last thing you want to do is to leave the aircraft incorrectly trimmed and have something happen to you. When you step up to jet aircraft, the most important control in the aircraft is the trim. Use it well and often.
Actually yes, it IS difficult unless you've practiced it. And most of us who practiced it had an instructor who recovered the plane when we fucked it up. And every pilot fucked this up in training.
Only in training? I'd say about 1 in 20 landings is still a fuckup compared to what we aim for... Once you get a few thousand hours experience, you'll probably still fuck up 1 in 50... True, the degree of fuckup is greatly reduced - but professional pilots with thousands of hours still bounce 737's etc.
This is so visually insulting that the only criticism I can give it is "start over."
Wow - you showed more compassion than me
Make one even better change. Allow comment moderation above +5 -- but only for this article...
Sadly, there is no way to impress upon the Dice morons how much people agree beyond +5 at these comments....
I agree 100% here. It's just sad that you can't moderate comments above 5 for others to realise how many people actually agree here. I think you'd find it'd be in the thousands....
It makes the comment section - which is a large part of the slashdot experience - seem like something tacked onto the end of a news article where people post one line responses.
By the way, if anyone hasn't gone and looked at the comments section on an article, go look now and then tell me I'm wrong.
Oh god. I really thought "It couldn't be that bad" - and then looked at the page linked above.
WHAT. THE. FUCK.
I've been around here a long time, and this has got to be one of the most braindead ideas I have ever seen on this site. You may as well convert slashdot to run on phpBB instead. At least then its still about the community and not the (limited) articles...
Slashdot's biggest selling point, as it's always been, is the conversation the stories generate.
Exactly. And how does the new design reflect this?
It doesn't - but it does make me want to stab someone in the face for turning neat and functional into flashy and useless....
Maybe someone got fired from the Gnome 3 team and picked up a gig at slashdot hq.....
Since I observed the process, I'll describe the process as I saw it.
The House votes are all dumped on a table and turned right side up. These were green sheets I'm guessing were 1/3 or 1/4 A4 sheets. Once that is done, there are other tables set up with 7 piles. Each vote is put there by the primary vote (i.e. the #1 vote) or they are set in the "informal" pile. Some people were very efficient with this as they would take a stack and remove all the $major_party1 but others would run around the table place ballots. (Kunth Vol 3?) Once those are done, they are all counted and the #3->#n piles are then checked for preferences. That means deciding which of the 2 major parties gets the by deciding which number is lower, the 3rd box or the 9th box. The ballots are also not cut nice so the middle boxes aren't in the same position and this appears to be a highly error prone process. There are some clues for rapid sorting (i.e. the 9th box has a 9 so they don't get that vote) but the rest is just tedious work. The forms (The Election peoples, and parties Libs, Labor, Greens) all seem to assume a Lib/Labor are going to win #1 and #2.
Once the second preferences are counted, they are called in to the main counting room and all the party reps call them into their campaign HQs.
The Senate count is more of a pain because the ballots are letter sized tall and about yard long. That makes then very hard to sort and same procedure above is used with less efficiency. You can't have nice neat piles on a table since you need several tables to hold all the paper just for the major parties. They had to go with the floor for the minor parties and the below the line votes took even more but that might have been a result of not having any sort of advice on even how to approach the problem (they should have sorted by party next to the others and then sorted by candidate but what do I know, I can't can't even cite the optimum selection sort variation out of Kv3)
