What does "E.F. or F.F.?" mean?

site: Robert A. Heinlein - Archives - The RAH FAQ
This phrase appears several times in Time Enough for Love, most notably in the "Dora story." It means, simply, "Eat first, or f**k first?" and is believed to be old Navy slang (perhaps shorthand for "You wanna get some real food or some tail first?" on first hitting dirt for shore leave). Dora's reply of "Both!" might confuse some readers, but is completely in character, if you think about it - and has a couple of alternate meanings, as well.

What is EF?

See My Heart - by The American Society of Echocardiography
Ejection Fraction (EF) is a key indicator of heart health and is frequently used to determine the pumping function of the heart. Simply stated, EF is the amount of blood pumped out of the heart during each beat or contraction. In a healthy heart, 50-75% of the blood is pumped out during each beat. This indicates that the heart is pumping well and able to deliver an adequate supply of blood to the body and brain. Many people with heart failure and heart disease pump out less than 50%.

What does the Energy Factor (EF) on my water heater mean?

GAMA: an association of appliance manufacturers
The water heater Energy Factor (EF) is a measure of the overall efficiency of a water heater determined by comparing the energy in the heated water used daily to the total daily energy consumption of the water heater. The EF can be used to compare the energy efficiency of models. Water heaters with higher EFs will have lower annual operating costs than comparable models with lower EFs. I am not a GAMA member but I have a really technical question and wish to talk with someone about it.

How does the Canon EF 100 400 L IS compares to the Canon EF 70 200 L f/2.8 IS?

FAQ: Canon EF 100 400 L IS at All Day I Dream About Photogra...
This one is unanimous, all the forums threads I’ve read agrees that the Canon EF 70 200 L f/2.8 wipes the floor, or if you prefer wins hands down against the Canon EF 100 400 L IS in their overlapping zoom range. Well it depends on the teleconverter itself, it seems that the Canon EF 70 200 L with a 1.4x has a slightly better image quality than the 100 400 L, but that the Canon EF 100 400 L IS wins if you decide to add a 2x teleconverter to the Canon EF 70 200 IS L f/2.8

Why does my content shift to the left on some pages (in FF)?

BonRouge : CSS Frequently asked questions
That'll be the pages with more content? The ones that have a vertical scrollbar? If you look in IE there's probably a white space on the right where there would be a scrollbar if there were enough content to require one. In Firefox, the scrollbar appears when it's needed and the viewport becomes about 20px smaller, so the content seems to shift to the left when you move from a page with little content to one with lots of content.

On the EF, when using the VNbus, does the FDDI interface show any transmit CRC errors?

Digital Networks Partnerships
Redirect to the VNswitch after load process has started. Press the return key will indicate that the module is in the load state. Another way is to use the bootp loader instead of the ClearVision router. The bootp loader gives a status of the module during the load process. To start the bootp loader use windows explorer and find the clearvision folder. Open it and find the comet folder, open this and find the bootp file, double click to start it.

How can I place e.g. the bookmarks button in both AiOS and in FF toolbar?

Normally this is not possible, because there is always only one button for one function. But nevertheless you have two possibilities to get doubled buttons. You can use Custom Buttons² or Customizable Toolbar Buttons to create a second button for one job. Use following workaround, which is actually a bug (I believe it's a Firefox bug, but I'm not really sure. :-)) configure the other toolbars to your needs.
