Where can I find documentation on how to use the \nolinebreak command?  The  at  never makes mention of \nolinebreak  The  states that \nolinebreak is implemented by multiplying its input parameter penalty by (-1) and passing the result into \nopagebreak.       I haven't found documentation on how to use the command.
how to use these hash functions in python? In this article , specifically in the section 4.1 of the initialization phase,the following cryptographic hash functions have been chosen: \begin{align} h_1&amp;:   \mathbb G\to\mathbb Z_q^*\\ h_2&amp;:  \{0,1\}^*\times\{0,1\}^*\times\mathbb G\to\mathbb Z_q^*\\ h_3&amp;:  \{0,1\}^*\to\mathbb Z_q^* \end{align} where G is an additive group with order q. Can anyone explain to me what's the meaning of their notations and how to use them for example in SHA algortihm? Or maybe give me a simple example with real inputs? Classify orbits of conjugating action on $GL_2(\mathbb{C})$ What is terminal velocity? I've heard the term especially when the Discovery Channel is covering something about sky diving. Also, it is commonly known that HALO (Hi-Altitude, Lo-Opening) infantry reaches terminal velocity before their chutes open.    Can the terminal velocity be different for one individual weighing 180 pounds versus an individual weighing 250 pounds? Clicking on tags in global search results is broken Computer wont boot to windows I recently installed a Linux operating  system (backtrack 5 r3) I couldn't connect to the internet with it so I removed the partition manually. After that, whenever I turn on my computer it goes to a command line that says "error no File-system found" "Grub Rescue/"  I have tried f12 and booted into all the options. I also put Ubuntu 12.04 on my flash drive and tried installing it on the computer, the installation failed saying "No Available Space"  My hard-drive is 500g with about 250 left. I put the hard drive in another computer (as a secondary just to see the files. It had 2 partitions a main and one with 1 gig. I formatted it with no difference.  My Problem: I can't boot into Windows How to create a procedural chevron like texture/material? I'm playing around with nodes within cycles and I'd love to create a chevron like texture like the image below. Anyone an idea how to accomplish this? Difference between static class and singleton pattern? how is this picture made? Good day guys, i have to something like this, any idea how is this picture made ?  so it looks like negative i did invert it in photoshop but the bright side of his face was blue, so there been negative effect and smting been used to change his face to blue before nagative or smting that changed his face to normal skin color after negative ? what can it be ? what do you guys think ? THANKS ! for help. How do i test capacitors? I've just gotten through replacing capacitors on a trio of dead LCD screens (nothing's blown up yet, so far) - they either had one or two capacitors on their inverter circuit SLIGHTLY bloated, and not quite leaky. I ended up replacing all capacitors of the same brand/'colour', even the ones that looked fine, in case.  Now, checking a bad resistor is simple - i can use a standard multimeter to test it, and i tend to check my solders with the continuity testing option of the multimeter.  How would i test a capacitor ? Is there some standard, common way to test one? Run a script as root from apache Is it correct to use that/which in the relative clause when it is referring to the place as an object pronoun? Does a run scored on a tag out on a forced runner? The situation:   Runners at third and first, ball is hit to the second basemen, 2nd basemen goes to tag the runner out. Runner stops, runner on third scores and then 2nd basement tags the runner, does not step on base.Does the run count? What does \x mean in C/C++? Does driving an microcontroller's GPIO when it is powered off weaken the chip? We are using the  in a project. The way our design is now, the IC's GPIO pins will sometimes be driven high (to 3.3V) or low when it is powered-off. Will this weaken the chip? The absolute maximum ratings state the voltage on any digital I/O pin is -0.3V to VSupply+0.3V. If the answer is no, could the IC be weakened during power up?  The LTC5800-IPM does not have the most detailed datasheet. If it is not clear for that device in particular, I'd be interested to know for CMOS microcontroller GPIOs in general.

Best way to restrict access by IP address? For an ASP.NET C# application, we will need to restrict access based on IP address. What is the best way to accomplish this? Most efficient way to convert an HTMLCollection to an Array Is there a more efficient way to convert an HTMLCollection to an Array, other than iterating through the contents of said collection and manually pushing each item into an array?
