Well, the problem with this is that it's from one point of view (his location).
I've been working on my own maping project on and off for about a year now. It uses AT&T's "Dot" to make the maps.. I use somewhat diverse locations, and build a huge routing map out of it all, along with latency and packet loss numbers.
There's a brief example. Imagine you have 4 locations, each represented by a corner of a box.
A ----- B |\/| | \ / | | X | | / \ | | / \| C ----- D
He's viewing from "A". For him, the routes from A to B and A to C may not be used, or may not even exist. So, his traffic would go from A to X to B,C,or D.
For D to go to C, he may be forced to go to X, A, then C.
It's all in the contracts for peering. Nothing that us folks in the real world can do anything about. On my project, I do see completely different routes depending on what city I tested from with the same provider, and different routes from different providers in the same city. His map is far far far from complete. He'll need to get machines to test in very diverse locations on the Internet to show so many more routers.
That's where I'm having problems on my project. My map is absolutely *HUGE*. I have very small print labels on each hop, and small text saying latency and packet loss on each route. To view it, I take the result image into a graphics program, and scroll around til I find what I'm looking for. Usually I have a good idea of where it is.. The only other viable option for seeing it, is to print it, but it needs to be several feet wide to even be able to read any of the text. {sigh} Of course, I want something that's functional, not just eye-candy saying "This is the Internet".
What I've done for people who have needed to transfer their Windows install, without loosing anything (i.e., not having to reinstall the 100+ applications they've installed), I boot up with a Linux CD (distro or one of my own), and use cat to duplicate the data. I know a lot of people use dd, but hey, there's always more than one way to do it.:)
cat/dev/hda >/dev/hdb
For my Linux stuff, I use tar, something like this:
cd / ; tar cvpzf/some_path/backup.tar.gz.
I suppose it may work with Windows installations, if you have CONFIG_FAT_FS, CONFIG_MSDOS_FS, CONFIG_VFAT_FS, and CONFIG_NTFS_FS, depending on what filesystem your Windows machine is using. Try it once, and see what happens. You may find this works, and is free, rather than the expensive alternatives.
mount/dev/hda/dos ; cd/dos ; tar cvpzf/some_path/backup.tar.gz.
Network god was meaning the god of a particular network.:) I reign god on my networks, but I can do little as far as fixing other people's networks, unless they ask me to. I only do the impossible miracles on my networks and equipment.:)
The classes are still defined, although yes, the concept is mostly dead. But, aparently Cisco at least still prevents using the Class E networks on their routers. Read This. If those networks are opened up in the future, it would mean a whole lot of upgrading to routers around the world. Well, a similiar level of upgrades that would be required for ipv6. I've been hearing about ipv6 since I started seriously working on the Internet. It's really just one of those future-looking dreams that will probably never come about for general use. I know people will argue that til they're blue in the face. People used to argue the fact that computers will never exceed 100Mhz (on FidoNet, when the i486/33 was just released), due to radio interference and hazards due to the high frequency emissions. Hey, I didn't make the arguements, I just listened.
People are aparently not *THAT* concerned about spam. If they were, someone would have already worked out a suitable replacement, that admins would already be gating messages for, and converting their users to. I've been thinking of solutions myself, but don't have time to write, test, or implement them.
I finally took the CCNA class. Been working with the Cisco hardware for years, but finally took a class. I couldn't get the routers to assign class E addresses.
But, for those that don't know, the CCNA book says:
Class A 0.0.0.0 to 127.255.255.255
Class B 128.0.0.0 to 191.255.255.255
Class C 192.0.0.0 to 223.255.255.255
Class D 224.0.0.0 to 239.255.255.255
Class E 240.0.0.0 to 255.255.255.255
Class D are multi-cast, which I don't believe very many people use..
Class E are "Scientific Purposes" or "Research".
I was running a little personal project a while back, to try to find logical distances from various points (places I had access to machines) to other places, and try to map them, to determine if there were more advantagous places to put servers, or redirect customers on particular networks to particular servers.
A whole bunch of those first/8's don't have anything in them, or at least nothing reachable by a couple different methods. My tests weren't completely exhaustive. I didn't try every port on every IP. I just did a sampling of IP's for a few different ports and packet types. So, there are a whole lot of unused IP's out on the Internet.. Looking at the logs of some of our sites, with over 1 million uniques/day, you can see where the IP's are clumped up, and huge gaps in the usages.
Of course, if I was the network god of 3.0.0.0/8 (General Electric), and I was only using say 100,000 IP's, they'd be hard pressed to make me give up any part of that, especially in knowing that they've had that block since the first days of the Internet. Whois says they registered 3.0.0.0/8 in 1988. I definately wouldn't want to be the admin that had to change 50,000 IP's.
I guess it does help with the old estimates, that people are using NAT more frequently. The stories I heard years ago said we would have run out long before Y2k, but since people run NAT's at home and many offices. Nextel has assigned IP's to every phone (ahhh, the wonders of the Internet), but they're all 10.0.0.0/8.
For example, on my phone, I select
Menu -> More -> My Info -> Carrier IP
And it shows me 10.154.85.xxx
Using a Nextel im1100, I also get assigned an IP in the 10.0.0.0/8 network.
For those that don't know, 10.0.0.0/8 is a private network. You can use it any way you'd like, but it's completely useless to you on the Internet unless there's a NAT or something between you and the rest of the Internet.
At the Free Internet Press (freeinternetpress.com), we've gotten quite a few spammers posting their ads as news articles. They're obviously oblivious to how we work. The site is slashcode. It's the same as submitting a story to/. . We read the story, fix any errors (spelling, formatting, or whatever), add our own comments, and then post it. Spam would never make it through as a news article. But, they keep trying. {sigh}
I wrote something like that into a messaging system that I wrote once..
If you go to voyeurweb.com (warning, porn site), and select any set of pictures, at the bottom there's a link where users can post their comments.
Anyone can write there, and frequently enough they write really rude comments. The people contributing the pictures don't like it, the people posting nice comments don't like it, so I added in a button, that simply keeps a record of how many people have clicked the alert button. The text of it is:
"Alert! Click Here to let the VW Ops know if this is a rude message."
The idea is simple enough, it remembers (SQL DB, of course) how many unique complaints were made about a particular message, and the message monitors get that list, sorted by the number of complaints. The users are pretty good about complaining, and are more than happy to click the button.
It's fairly free of abuse, because messages that have more complaints from more users are the bad ones. Of course, there are people who complain about perfectly normal messages, but that's why we have people actually reviewing the messages before they're removed.
There's a whole lot more to it than just the alert button,
To me, it's very wierd, it's an adult site, and you'd think that most people are just there to look at the pictures, but there are a significant number of people posting messages there, and they are just about as fanatical about it as/. posters are about/. .:)
The system as a whole works very well. We have 3,363,465 messages in the system (I purge old messages every few months), 5 alerts that haven't been read, and 43 IP's or networks that have been blocked. They have the power to prevent any size network from posting in the future, if the abuses have been bad enough. Most of the abuse and filtering features have grown with the messaging system over the years. When I originally wrote it, it didn't have or need any of it. It's fairly complete now, I haven't done any significant changes in years.
"This release is going to be driven by technology, not by a release date"
"But we have to make sure that we really take on something dramatic, like 32 bit computing eight years ago, or the NT kernel in Windows XP."
Gates told reporters that Microsoft won't stop the development of its browser Internet Explorer
"How could we ignore the browser?," Gates responded. 'The Explorer is fully integrated with the operating system, take it away and the OS grinds to a halt. When you call up Help, you're using the browser. In Office 2003 instead of going to the local files, the browser will go online and fetch the latest documents."
"XML is going to be the key technology here too."
The BIOS will always be separated from the operating system. Actually, it's gotten out of date. If you run Windows XP, it calls very little of the BIOS.
"But apart from Photoshop, I can't think of desktop applications where you would need more than 4 gigabytes of physical memory, which is what you have to have in order to benefit from this technology. Right now, it is costly."
"It appears more magical than it really is. Even with 32 bit computing, I couldn't help noticing a level of enthusiasm that went beyond its technical merit."
Microsoft invested over $100 million to refocus on building products that strive to be secure by design, by default and by deployment.
"None of the security problems recently affected people who had their software up to date,"
We invented personal computing. It is the best tool of empowerment there has ever been.
Like I said, a big load of PR crap.
If I read that right, he's right back to having us on 16bit processors with minimal memory. Unfortunately, his own OS can't handle it.
I liked that 32bit was a big deal in the second quote, but in the 8th quote it wasn't. Sounds like he's trying to set himself up for not having to support 64bit processors, except in a 32bit compatability mode (remember the DEC Alphas?)
It's a big "We made the PC, we make the software, you will take it, and you will love it!", then the crowds applaud, and a couple hundred thousand *nix folks roll their eyes and `ping -f microsoft.com` (ya, I know, dozens of better things to do, it's for illustrative purposes)
As one of JetBlue's first passengers, when the seats were still new and the TV's weren't working yet, I'm upset by this. I flew them in the first weeks they were flying, and then frequently afterwards, because the planes were nice, the service was good, and the rates were cheap. Now I'm even more screwed than normal, I'm deep in the belly of the CAPPS II system. Bastards.
It was very nice of them to include the SS#, address, and date of birth. I recognize some of the addresses on pg 20 of the PDF, it would be almost trivial to find out the names to go with those, and use them in identity theft.
I wouldn't do it, but I might anonymously mail a printout of the pdf to them.
This has brought up a discussion here in the office, when the hell did CD's become popular? I got my first CD player in my car in '89, but everything I had was on casette tapes. Ahhh, the days of hair-band hair, slutty girls, cheap beer and loud music. What happened to those days?
Looking around a little, it was Philips and Sony that released the first CD players in '82, but it appears that "Licensed to Ill" was released in '86 and wasn't available on CD til '90.
I can't imagine every store going back and changing the covers for licensed to ill, 11 years after it's released. But knowing the climate immediately after 9/11, maybe they did.
Ahh, listening to Beastie Boys.. I gotta find my CD. The tape wore out years ago.:)
The Beastie Boys had an illustration of this material in use on their original "Licensed To Ill" tapes. Unfortunately, I lost the tape sometime in high school, and was only able to find This Picture of a 1986 press pass on beastiemania.com:) Aparently the CD and/or album cover didn't have the same graphic on it.
There's a wonderful invention they made a few weeks ago, called a thermostat.:)
Ok, sarcasm is on high today.:)
Home air conditioning units, the coils are at 40F, so it isn't a dramatic change from that. Cool the surface, run a fan across them, and when the room reaches the desired temperature, cut off the peltier elements and store the electricity from the cells.
Funny, I was just thinking about something like this.. My idea wasn't transparent though. Generally, office windows are too big, and frequently blocked by furnature. 8-foot tall windows do give a pretty good surface area to work with.
What if....
Take a reasonable area of the window, and mount solar cells and peltier elements flush to the window. Admitted, it won't work on all sides of the buildings, but 50% of most buildings could use it.
The solar panels aren't enough to say run the whole office, but they would be good for powering the peltier elements, and supplementing the building power. Say it took 25% of the load off the building, that would be substantial.
Peltier elements are usually good for a 70 degree difference in temperature between the front and back of the element. So, if it's 100 degrees on the hot side, it could be 30 degrees on the cool side. Ahhh, on a 100 degree day, wouldn't it be nice to be in a cold office?
Many buildings (architects can argue this all day) have a decent space between floors, for ducts, plumbing, power, and the thickness of the floor itself. The outside of the building in those spaces is unused non-window space. If the buildings, by design, used that space for solar panels, and used peltier coolers as part of their cooling system, cooling at least part of the outside surface in the summer and heating it in the winter, the power reduction would be tremendous.
Most of the buildings I've worked in for long durations were in the southern part of the US. Those buildings usually require cooling year round to maintain the appropriate temperatures, thanks to all the hot equipment we run inside.
Well, what I had read gives you a bit higher than 20%, but not much higher.
On a 5 question test, your choices are A B C D E.
Teachers tend (for whatever psychological reason) to avoid putting the right answers on A or E, but that's not good for 100% obviously. If they're avoiding A and E, your probable answers are B C D . 30% chance now.
If the class your taking lets you review the tests afterwards, take note of the right answers, and where they fell. I've had teachers who had almost a 50% chance of the answer being "E".
If the tests are computer generated, the probability for any particular letter should be exactly the same, unless there's an error in their code.
But I believe what he was trying to cite is that if you pick the same letter for every question, you should get 20% (5 answer) or 25% (4 answer). But, if the randomization was generated by hand or by some other formula (alphabetization of answers), or some other way to foul the system, the score will either be much higher or much lower.
A) True B) False C) All of the above D) None of the above E) Cowboy Neal in speedos
Obviously C and D are impossible answers, and unless the question is "Guess what I saw at the beach yesterday", E is unlikely too.:)
I was fond of picking "B" if I didn't know the answer. It was right about 20-25% of the time.:)
Usually an $85 meal includes more food and/or more people, or we lingered at the table longer and they had to bring us more drinks, or whatever. At least that's the way it works with us. I'm definately not much of one to go for $100/plate dinners..:)
I've been to other places in the world, but I fell asleep on the plane, so I have absolutely no proof that they didn't circle for 12 hours and land me at the Euro-Simulator in bum-fuck Nebraska.:)
Of course, I believe California was a creation of the media til I drove out here. 2000 miles due West will really remind you that maybe you shoulda hung a left at Albuquerque.:)
US Federal law says that staff who earn part of their wages from tips must be paid at least $2.13/hr.
Many restraunts do that. You work, you get $2.25/hr (or whatever the boss is nice enough to pay you). So in most places, the staff are very dependant on your tips.
I tip 20%, and then adjust by service. If the service seriously sucked ass, you may get nothing. If you were really good, you may get 20% rounded up to the nearest $10. ($85 dollar meal would get a $20 tip). Knowing most people are complete idiots who don't tip for good service, it's worth it for me for two reasons. 1) they deserve decent pay if they did a good job. 2) I expect good service next time I come in, and will probably get it. Usually if I tip well and come back another day, I get better than average service. Places I go regularly, I don't have to ask for my drink, they'll have it ready by the time I'm seated.
But, tipping doesn't excuse impoliteness. Well, you probably wouldn't get a tip if you're looking at all your customers saying "What kind of idiot....", but the polite waiter gets pleases and thank you's, and a good tip.
But in some parts of the world, this isn't expected or acceptable. I gave a taxi driver in Europe a $10 tip for getting me from point A to point B in no time. He was polite, held the door for me, yada, yada, yada. He was completely flabergasted that I gave him anything extra.
In New York, I gave a taxi driver $20 for getting me from Times Square to the WTC in less than 5 minutes. Of course, stop lights and lane markings are frequently meaningless, so that helped accomplish the time.:) It saved my ass though, I had to be in like 3 places at once, and got everything accomplished on a very short timetable.
In some US cities, you may be lucky the car doesn't hit you driving away if you don't tip.
Flight attendants don't take tips, and get offended when you offer one. I haven't quite figured that one out yet. If I buy a beer from a fight attendant, they are the bartender, and the bartender always get tipped.
So, maybe in the UK you don't take tips, fine. In some countries it's most of the money that they make. In some jobs it's the majority of their paycheck.
I don't tip because I have extra money. I tip because I've worked just about every shit job there is at some point in time, and can completely relate to them having to deal with asshole customers every day who think that $2.25/hr actually pays the rent in most metro areas.
I haven't played with RAID's other than RAID5 much, but here's my experiences. Maybe they'll help your opinion.
I've used several different external RAID5 solutions, including the Promise TX8000 and Radion arrays (and a bunch of no-name brands too). Those all worked beautifully, and survived failures without any significant problems.
I've worked with four internal hardware raid solutions. Two were the Adaptec AA-130 cards years ago, and the most recent two were Promise SuperTrak SX6000. One belonged to a friend, and one went in my machine.
My friend had several problems with his. I'll leave his story at that.
I put together a nice dual processor machine for a large photo archive site. It needed lots of space, which is why we needed the RAID5. It also needed to take up as little space as possible, so we opted for putting 6 drives in a 2u case with the SX6000. The card was incompatable with the newer chipset of the motherboard. It took two weeks of daily calls to tech support before we gave up. A week later, they released a firmware update which addressed this problem. The SX6000 doesn't handle heavy read or read/write traffic very well. When we made it an active web site, the server would crash very frequently with errors about the array. If we kept the traffic slow, it worked fine, but that what we wanted from this machine. This array solution proved to be non-functional for us, so we made the machine a backup machine, so now we have like 600Gb of storage space to back servers up to.:)
I've heard a lot of good things about 3ware, but haven't tried one myself yet.
I've been experementing with Linux's software RAID's. I've used RAID1 and RAID5, and they both work great. I've had a drive fail on two so far, but for the number of drives we use, that's acceptable. They rebuilt fine sticking in a new drive, with very little performance hit. I do like that Linux gives decent statistics in/proc/mdstat.
You seem to want multiple platforms, so I guess Linux software RAID isn't much of a solution for you.
I can simply warn against the Promise SX6000. It should have been a good card, with Promise's reputation, but I was severly disappointed.
Over the years, I've had accidents with electricity. Never made the same mistake twice.
110v AC house electricy, wiring fault. Left my hand tingling for about an hour.
90v AC phone line (ring), just a tingle (mental note, don't touch the "ring" line when the phone is ringing).
10kv DC motorcycle ignition (miswired). left my arm numb for about an hour.
30kv DC car ignition from spark plug wire (not seated on spark plug correctly). left my arm numb for a few hours.
300kv stun gun with a wiring fault. Zapped out of the handle rather than the business end.
None of these were for very long, which is much of why I survived. All of them, the muscles where the power was flowing cramped up. In other words, if I had been holding onto something, I wouldn't have been able to let go. If you're grabbing what you thought was a dead wire, and found it to be live, you may not be able to let go, no matter how much you want to. People get dead all the time like this, most didn't do it intentionally.
If you mess up, and leave a wiring fault, you'll can be criminally neglegant for someone's death if you electricute them, or start a fire. Electricity can be dangerous. Don't rewire a building, unless you know what your doing (trained, certified, and licensed). If you're not comfortable with letting someone else to do the work because they may do a bad job, stay around and watch their work. Ask questions, "Why aren't you grounding that circuit? Is just electrical tape appropriate there? Is 24 gauge wire right for a high load circuit?".
Some places require locks and tags to be sure the power doesn't accidently get turned back on while you're working.
I spent some time at a Walmart warehouse. Big facility, lots of cool conveyor belts. They made a *HUGE* point of tagging and locking anything you're working on. I guess it only makes it slightly more hazardous that all their racks are metal, so if you have a main wire disconnected, and it was touching the metal of the racks, you could make an electrical hazard out of a piece of metal 3 stories high and a couple hundred feet long.:) Luckly, I didn't even work in a department that did physical repairs. We were just warned so some idiot wouldn't turn on a conveyor (or whatever) that was intentionally shut down.
Slashdot Mirror
Unfortuantely, just after Krow left is when we started seriously using Slashcode.. :(
:)
:)
I wonder when Slashcode will be updated with the new HTML scheme, or even when it will next be updated.
Slashcode 2.2.6 seems to be the last stable release, in July 2002.. I thought only Microsoft was so slow on new releases.
If that didn't rattle a few cages, I don't know what will.
Well, the problem with this is that it's from one point of view (his location).

At the Free Internet Press (freeinternetpress.com), we've gotten quite a few spammers posting their ads as news articles. They're obviously oblivious to how we work. The site is slashcode. It's the same as submitting a story to /. . We read the story, fix any errors (spelling, formatting, or whatever), add our own comments, and then post it. Spam would never make it through as a news article. But, they keep trying. {sigh}
I wrote something like that into a messaging system that I wrote once..
If you go to voyeurweb.com (warning, porn site), and select any set of pictures, at the bottom there's a link where users can post their comments.
Anyone can write there, and frequently enough they write really rude comments. The people contributing the pictures don't like it, the people posting nice comments don't like it, so I added in a button, that simply keeps a record of how many people have clicked the alert button. The text of it is:
"Alert! Click Here to let the VW Ops know if this is a rude message."
The idea is simple enough, it remembers (SQL DB, of course) how many unique complaints were made about a particular message, and the message monitors get that list, sorted by the number of complaints. The users are pretty good about complaining, and are more than happy to click the button.
It's fairly free of abuse, because messages that have more complaints from more users are the bad ones. Of course, there are people who complain about perfectly normal messages, but that's why we have people actually reviewing the messages before they're removed.
There's a whole lot more to it than just the alert button,
To me, it's very wierd, it's an adult site, and you'd think that most people are just there to look at the pictures, but there are a significant number of people posting messages there, and they are just about as fanatical about it as
The system as a whole works very well. We have 3,363,465 messages in the system (I purge old messages every few months), 5 alerts that haven't been read, and 43 IP's or networks that have been blocked. They have the power to prevent any size network from posting in the future, if the abuses have been bad enough. Most of the abuse and filtering features have grown with the messaging system over the years. When I originally wrote it, it didn't have or need any of it. It's fairly complete now, I haven't done any significant changes in years.
Like I said, a big load of PR crap.
If I read that right, he's right back to having us on 16bit processors with minimal memory. Unfortunately, his own OS can't handle it.
I liked that 32bit was a big deal in the second quote, but in the 8th quote it wasn't. Sounds like he's trying to set himself up for not having to support 64bit processors, except in a 32bit compatability mode (remember the DEC Alphas?)
It's a big "We made the PC, we make the software, you will take it, and you will love it!", then the crowds applaud, and a couple hundred thousand *nix folks roll their eyes and `ping -f microsoft.com` (ya, I know, dozens of better things to do, it's for illustrative purposes)
I found my CD tonight. If you unfold the cover, it does have the full plane picture on it. :)
As one of JetBlue's first passengers, when the seats were still new and the TV's weren't working yet, I'm upset by this. I flew them in the first weeks they were flying, and then frequently afterwards, because the planes were nice, the service was good, and the rates were cheap. Now I'm even more screwed than normal, I'm deep in the belly of the CAPPS II system. Bastards.
It was very nice of them to include the SS#, address, and date of birth. I recognize some of the addresses on pg 20 of the PDF, it would be almost trivial to find out the names to go with those, and use them in identity theft.
I wouldn't do it, but I might anonymously mail a printout of the pdf to them.
Sure we did. :) Errr, maybe..
:)
This has brought up a discussion here in the office, when the hell did CD's become popular? I got my first CD player in my car in '89, but everything I had was on casette tapes. Ahhh, the days of hair-band hair, slutty girls, cheap beer and loud music. What happened to those days?
Looking around a little, it was Philips and Sony that released the first CD players in '82, but it appears that "Licensed to Ill" was released in '86 and wasn't available on CD til '90.
I can't imagine every store going back and changing the covers for licensed to ill, 11 years after it's released. But knowing the climate immediately after 9/11, maybe they did.
Ahh, listening to Beastie Boys.. I gotta find my CD. The tape wore out years ago.
The Beastie Boys had an illustration of this material in use on their original "Licensed To Ill" tapes. Unfortunately, I lost the tape sometime in high school, and was only able to find This Picture of a 1986 press pass on beastiemania.com :) Aparently the CD and/or album cover didn't have the same graphic on it.

Vacation? I don't leave my win2k box on when I go to WORK, lest a new exploit surrface before I get home :-)
:)
On? I don't own a Win2k machine. All mine are Linux.
There's a wonderful invention they made a few weeks ago, called a thermostat. :)
:)
Ok, sarcasm is on high today.
Home air conditioning units, the coils are at 40F, so it isn't a dramatic change from that. Cool the surface, run a fan across them, and when the room reaches the desired temperature, cut off the peltier elements and store the electricity from the cells.
Funny, I was just thinking about something like this.. My idea wasn't transparent though. Generally, office windows are too big, and frequently blocked by furnature. 8-foot tall windows do give a pretty good surface area to work with.
What if....
Take a reasonable area of the window, and mount solar cells and peltier elements flush to the window. Admitted, it won't work on all sides of the buildings, but 50% of most buildings could use it.
The solar panels aren't enough to say run the whole office, but they would be good for powering the peltier elements, and supplementing the building power. Say it took 25% of the load off the building, that would be substantial.
Peltier elements are usually good for a 70 degree difference in temperature between the front and back of the element. So, if it's 100 degrees on the hot side, it could be 30 degrees on the cool side. Ahhh, on a 100 degree day, wouldn't it be nice to be in a cold office?
Many buildings (architects can argue this all day) have a decent space between floors, for ducts, plumbing, power, and the thickness of the floor itself. The outside of the building in those spaces is unused non-window space. If the buildings, by design, used that space for solar panels, and used peltier coolers as part of their cooling system, cooling at least part of the outside surface in the summer and heating it in the winter, the power reduction would be tremendous.
Most of the buildings I've worked in for long durations were in the southern part of the US. Those buildings usually require cooling year round to maintain the appropriate temperatures, thanks to all the hot equipment we run inside.
Just my thoughts.
Well, what I had read gives you a bit higher than 20%, but not much higher.

On a 5 question test, your choices are A B C D E
Teachers tend (for whatever psychological reason) to avoid putting the right answers on A or E, but that's not good for 100% obviously. If they're avoiding A and E, your probable answers are B C D . 30% chance now.
If the class your taking lets you review the tests afterwards, take note of the right answers, and where they fell. I've had teachers who had almost a 50% chance of the answer being "E".
If the tests are computer generated, the probability for any particular letter should be exactly the same, unless there's an error in their code.
But I believe what he was trying to cite is that if you pick the same letter for every question, you should get 20% (5 answer) or 25% (4 answer). But, if the randomization was generated by hand or by some other formula (alphabetization of answers), or some other way to foul the system, the score will either be much higher or much lower.
A) True
B) False
C) All of the above
D) None of the above
E) Cowboy Neal in speedos
Obviously C and D are impossible answers, and unless the question is "Guess what I saw at the beach yesterday", E is unlikely too.
I was fond of picking "B" if I didn't know the answer. It was right about 20-25% of the time.
Usually an $85 meal includes more food and/or more people, or we lingered at the table longer and they had to bring us more drinks, or whatever. At least that's the way it works with us. I'm definately not much of one to go for $100/plate dinners.. :)
I've been to other places in the world, but I fell asleep on the plane, so I have absolutely no proof that they didn't circle for 12 hours and land me at the Euro-Simulator in bum-fuck Nebraska. :)
:)
Of course, I believe California was a creation of the media til I drove out here. 2000 miles due West will really remind you that maybe you shoulda hung a left at Albuquerque.
I'll better your bid by $1,000. But the hardware has to be intact. I want a working mainframe in my livingroom.
(Think they read
US Federal law says that staff who earn part of their wages from tips must be paid at least $2.13/hr.
:) It saved my ass though, I had to be in like 3 places at once, and got everything accomplished on a very short timetable.
Many restraunts do that. You work, you get $2.25/hr (or whatever the boss is nice enough to pay you). So in most places, the staff are very dependant on your tips.
I tip 20%, and then adjust by service. If the service seriously sucked ass, you may get nothing. If you were really good, you may get 20% rounded up to the nearest $10. ($85 dollar meal would get a $20 tip). Knowing most people are complete idiots who don't tip for good service, it's worth it for me for two reasons. 1) they deserve decent pay if they did a good job. 2) I expect good service next time I come in, and will probably get it. Usually if I tip well and come back another day, I get better than average service. Places I go regularly, I don't have to ask for my drink, they'll have it ready by the time I'm seated.
But, tipping doesn't excuse impoliteness. Well, you probably wouldn't get a tip if you're looking at all your customers saying "What kind of idiot....", but the polite waiter gets pleases and thank you's, and a good tip.
But in some parts of the world, this isn't expected or acceptable. I gave a taxi driver in Europe a $10 tip for getting me from point A to point B in no time. He was polite, held the door for me, yada, yada, yada. He was completely flabergasted that I gave him anything extra.
In New York, I gave a taxi driver $20 for getting me from Times Square to the WTC in less than 5 minutes. Of course, stop lights and lane markings are frequently meaningless, so that helped accomplish the time.
In some US cities, you may be lucky the car doesn't hit you driving away if you don't tip.
Flight attendants don't take tips, and get offended when you offer one. I haven't quite figured that one out yet. If I buy a beer from a fight attendant, they are the bartender, and the bartender always get tipped.
So, maybe in the UK you don't take tips, fine. In some countries it's most of the money that they make. In some jobs it's the majority of their paycheck.
I don't tip because I have extra money. I tip because I've worked just about every shit job there is at some point in time, and can completely relate to them having to deal with asshole customers every day who think that $2.25/hr actually pays the rent in most metro areas.
I haven't played with RAID's other than RAID5 much, but here's my experiences. Maybe they'll help your opinion.
:)
/proc/mdstat .
I've used several different external RAID5 solutions, including the Promise TX8000 and Radion arrays (and a bunch of no-name brands too). Those all worked beautifully, and survived failures without any significant problems.
I've worked with four internal hardware raid solutions. Two were the Adaptec AA-130 cards years ago, and the most recent two were Promise SuperTrak SX6000. One belonged to a friend, and one went in my machine.
My friend had several problems with his. I'll leave his story at that.
I put together a nice dual processor machine for a large photo archive site. It needed lots of space, which is why we needed the RAID5. It also needed to take up as little space as possible, so we opted for putting 6 drives in a 2u case with the SX6000. The card was incompatable with the newer chipset of the motherboard. It took two weeks of daily calls to tech support before we gave up. A week later, they released a firmware update which addressed this problem. The SX6000 doesn't handle heavy read or read/write traffic very well. When we made it an active web site, the server would crash very frequently with errors about the array. If we kept the traffic slow, it worked fine, but that what we wanted from this machine. This array solution proved to be non-functional for us, so we made the machine a backup machine, so now we have like 600Gb of storage space to back servers up to.
I've heard a lot of good things about 3ware, but haven't tried one myself yet.
I've been experementing with Linux's software RAID's. I've used RAID1 and RAID5, and they both work great. I've had a drive fail on two so far, but for the number of drives we use, that's acceptable. They rebuilt fine sticking in a new drive, with very little performance hit. I do like that Linux gives decent statistics in
You seem to want multiple platforms, so I guess Linux software RAID isn't much of a solution for you.
I can simply warn against the Promise SX6000. It should have been a good card, with Promise's reputation, but I was severly disappointed.
Over the years, I've had accidents with electricity. Never made the same mistake twice.
110v AC house electricy, wiring fault. Left my hand tingling for about an hour.
90v AC phone line (ring), just a tingle (mental note, don't touch the "ring" line when the phone is ringing).
10kv DC motorcycle ignition (miswired). left my arm numb for about an hour.
30kv DC car ignition from spark plug wire (not seated on spark plug correctly). left my arm numb for a few hours.
300kv stun gun with a wiring fault. Zapped out of the handle rather than the business end.
None of these were for very long, which is much of why I survived. All of them, the muscles where the power was flowing cramped up. In other words, if I had been holding onto something, I wouldn't have been able to let go. If you're grabbing what you thought was a dead wire, and found it to be live, you may not be able to let go, no matter how much you want to. People get dead all the time like this, most didn't do it intentionally.
If you mess up, and leave a wiring fault, you'll can be criminally neglegant for someone's death if you electricute them, or start a fire. Electricity can be dangerous. Don't rewire a building, unless you know what your doing (trained, certified, and licensed). If you're not comfortable with letting someone else to do the work because they may do a bad job, stay around and watch their work. Ask questions, "Why aren't you grounding that circuit? Is just electrical tape appropriate there? Is 24 gauge wire right for a high load circuit?".
Some places require locks and tags to be sure the power doesn't accidently get turned back on while you're working.
:) Luckly, I didn't even work in a department that did physical repairs. We were just warned so some idiot wouldn't turn on a conveyor (or whatever) that was intentionally shut down.
I spent some time at a Walmart warehouse. Big facility, lots of cool conveyor belts. They made a *HUGE* point of tagging and locking anything you're working on. I guess it only makes it slightly more hazardous that all their racks are metal, so if you have a main wire disconnected, and it was touching the metal of the racks, you could make an electrical hazard out of a piece of metal 3 stories high and a couple hundred feet long.
