I'm not sure I follow. An "American option" as you call it has two dates - one is the vesting date (the first day the option may be exercised) and an expiry date (the date the option will no longer be valid).
It sounds like you are describing the options that are given out as an employment benefit. There is a different kind, traded on an exchange just like stocks are.
If a particular stock 'foo' is trading at $60 today but you think it is going to go up in the future, you can buy a "June $65 call" for some small amount of money. That option then allows you to buy a share of foo for $65 any time between the purchase date and the June expiration date (American style), regardless of what the stock price happens to be at that time. Obviously you would only exercise it when the stock price was higher than $65, since otherwise it would be cheaper to buy the share itself than to exercise the option.
You can also sell the option to someone else instead of exercising it. If 'foo' was trading at $75 in mid-May then your option would be worth somewhat more than $10 at that time. Figuring out how much more than $10 it's worth is what this article is about.
FYI, it sounds like NFS is unusually anal about its config files.
I remember trying to troubleshoot an IPSEC problem on OpenBSD several years ago. The problem turned out to be *trailing* whitespace after an IP address in the config file.
if it fails in a way that you never thought possible, how would you write an error message that describes the failure?
You say what it wasn't.
Start by #include <assert.h> and adding assertions that should never fail (such as being passed a NULL pointer). When one of them does fail, you will get a message saying what condition wasn't satisfied and the line number where it happened.
For system calls like open(), check for a result code of 0 (success) or one of the error cases that your program explicitly handles. For anything else, first print the value of 'errno' and then trigger an assertion failure. This is particularly useful when your open() fails randomly on something like EMFILE due to a file-descriptor leak in a completely different section of the program.
"Why not now"? Because slack-ass websites like the one you're currently browsing still haven't bothered to flip on the IPv6 switch. I have IPv6 at home (pretty much plug-and-play; just enable it on the Apple Airport base station and all of the LAN machines pick up an address) and the only site I've found to go to is "ipv6.google.com". OK, there's also a dancing turtle GIF on kame.net, but that doesn't really count.
Interestingly there is an "ipv6.slashdot.org" DNS entry. However it has no IPv6 "AAAA" record, only an IPv4 "A". Seriously guys, WTF? If a techie "News for Nerds" site can't be bothered to make itself available to IPv6 users then there's little hope for the rest of the web.
Do none of these people honestly know that The Register is one long lived, entertaining, and generally informative tech web site, and that it was the creator of the ever popular and true to life adventures of BOFH?
I agree with most of that, but the BOFH stories were around long before El Reg started publishing them.
Get a modern Diesel and you can fill it up with the same vegetable oil you use in your salads.
Don't count on it. I just bought a modern diesel (2011 Jetta TDI) and it's not rated for more than 5% biodiesel (due to the particulate filter in the emissions system and contamination of the engine oil IIRC). I don't even want to think about how badly straight vegetable oil would f*ck it up.
I thought a 'home run' was something else entirely. Involving a girl. A naked girl. I didn't know running in a circle was part of the process. Or running at all, for that matter.

On the other hand, if its a vapor-compression system like your fridge at home, yes it is in fact a pretty cruddy choice and any of the freon series would kick its butt (as a refrigerant, anyway)
In terms of performance, ammonia is one of the best refrigerants in vapor-compression systems. Freon is easier and safer for small systems but ammonia is preferred for large industrial applications.

The Amiga Turns 25

The Amiga was tied to the custom chip set. Even ROM revisions broke software.
ROM revisions only "broke" software that was already broken, relying on some undocumented quirk or accessing hardware directly instead of following the proper APIs.
Or some lower frequency (LF/HF) that will cover variable ground terrain better.
One radio to look at is the Yaesu FT-817ND. It's a relatively compact battery-powered unit that covers HF as well as VHF and UHF bands. However this unit is still much heavier and bulkier than a modern 144 MHz handheld.
Question for the original poster - who do you want to talk to? Is this mainly for communication within a group of hikers? Is it to reach someone at a nearby city, and if so will that person also have a radio? Do you need to make a telephone call from your radio?
I never said Watts per Hour WAS a unit of power / energy.
It's a rate of consumption of power / energy.
No it's not. It's a rate of change of power, something that is rarely relevant.
Watt: power. How many joules of energy per second are used by a device. This can be an instantaneous measurement or an average value over a longer time period.
Watt-hour: energy. The amount of energy used by a device drawing 1 watt, operating for 1 hour. Or 2W for 30 minutes, etc.
Consider the quantity "2400 watt-hours per day". This means that the energy used in 24 hours (day) is 2400 watt-hours. Dividing, this means the average power over that interval was 100 watts. Similarly you can talk about watt-hours per month, again a measurement of watts but with a scaling factor based on how many hours are in a month.
Another nuclear accident not involving US weapons was the failed Soviet spy satellite Cosmos 954 which smeared a nuclear reactor core over a large part of northern Canada in 1978.
This was one of a family of satellites. Several reactor cores are still up in orbit, for now...
The only REAL fix is to disable the sequence in the modem.
Or to buy a modem from a manufacturer that implemented it properly. The escape sequence is not just "+++" - there has to be an interval before and after those characters in which no other bytes are sent to the modem. This can only happen if you're typing directly from a terminal, since there are always extra headers present if you're sending TCP/IP traffic.
If your modem was vulnerable to this then the manufacturer was either incompetent or intentionally screwing it up to avoid paying patent royalties.
As long as they use the correct prefix, I don't really mind whether they use base 2 or 10 to display the numbers.
RAM sizes are naturally powers of 2 due to how the individual memory cells are addressed, so it makes sense for RAM capacity to always be listed in GiB.
Hard drives, on the other hand, have nothing that is fundamentally based on a power of 2. They arbitrarily use a sector size of 512 (or 4096) bytes, but everything else (number of heads, number of tracks, average number of sectors per track) has no power-of-2 connection. Therefore there's nothing wrong with reporting their size in SI notation.
The original shorthand of calling 1024 bytes a "K" was not too bad because it's only a 2.4% error. However the error gets worse as you go up each level, and by the time you're talking about a TB/TiB it's something that people actually care about.
1. And all those expansion slots on the C64 are where again?
On the back. From what I remember there was a cartridge port (mostly games, although you could put memory expansions there as well), the "user" port (generic I/O, often used for modems), and a multi-drop serial bus (disk drives, printers, etc).
Sure there weren't as many slots as some other architectures, on the other hand the basic computer already had built-in support for sound, mouse, joystick, etc.
Prompt, efficient and convienient! Where can I buy this Root Kit?
Sony will sell you one although it's not 100% compatible with the industry-standard ones and it lacks the features of the rootkit described in this article. On the plus side, Sony bundles a free music CD with theirs.
(Yeah, I know they've allegedly stopped doing that. Never forgive, never forget.)
There will be a distillation stage in production, which requires a heat source. Where will they get this heat? (Hopefully, by burning some fraction of the ethanol they've just produced, or some of the feedstock.
Burning the ethanol product would be, shall we say, counter-productive. You might be able to get some heat from burning other volatiles produced during the fermentation process (like methanol).
It may be possible to use waste heat from some other industrial process located next to your distillation facility (e.g. steam exiting from a power-plant turbine at greater than 100 degrees C). You could burn agricultural waste, household garbage, old tires, pine-beetle-infested trees, or any other cheap and locally-available fuel.
A more sophisticated method would be to use a heat pump. It's not that big of a temperature difference between the boiling point of water and the condensing point of ethanol. You can move a lot of heat with a relatively small amount of mechanical work. This can be done by compressing the alcohol vapor itself (so that it condenses above 100 degrees C, boiling water in the process) or you could use a working fluid like hexane that had an appropriate boiling point.
