  • Have some chrome-extension script in my webpage, and was wondering what it does?

    Hi, I built my website using a tool, and I found that it's left script and meta tags within the header, and I was wondering if anyone knows what they actually do? I couldn't seem to find anything searching around on Google.

    The relevant code is below:

    <script src="chrome-extension://lifbcibllhkdhoafpjfnlhfpfgnpldfl/document_iterator.js"></script>

    <script src="chrome-extension://lifbcibllhkdhoafpjfnlhfpfgnpldfl/find_proxy.js"></script>

    <script src="chrome-extension://lifbcibllhkdhoafpjfnlhfpfgnpldfl/get_html_text.js"></script>

    <script src="chrome-extension://lifbcibllhkdhoafpjfnlhfpfgnpldfl/global_constants.js"></script>

    <script src="chrome-extension://lifbcibllhkdhoafpjfnlhfpfgnpldfl/name_injection_builder.js"></script>

    <script src="chrome-extension://lifbcibllhkdhoafpjfnlhfpfgnpldfl/number_injection_builder.js"></script>

    <script src="chrome-extension://lifbcibllhkdhoafpjfnlhfpfgnpldfl/string_finder.js"></script>

    <script src="chrome-extension://lifbcibllhkdhoafpjfnlhfpfgnpldfl/change_sink.js"></script>

    <meta name="document_iterator.js">

    <meta name="find_proxy.js">

    <meta name="get_html_text.js">

    <meta name="global_constants.js">

    <meta name="name_injection_builder.js">

    <meta name="number_injection_builder.js">

  • Best way to make up a certain amount of money with coins?

    Basically, I'm interested in the most efficient way to make up a certain amount of money, say 97p or 99p (given 1p, 2p, 5p, 10p, 20p, 50p, £1, £2 etc. coins).

    Instinctively, I'd say take the largest coin first, so that:

    47p = 20p + 20p + 10p + 5p + 2p

    But I can't prove that this is the most efficient way. And for different sets of coins I can find examples where it definitely isn't the most efficient way:

    1. If you have 1p, 2p, 5p, 7p, 10p,... then taking the largest first would give 14p = 10p + 2p + 2p, but the most efficient option is 14p = 7p + 7p

    2. If you have 1p, 2p, 4p, 9p, 20p,... then taking the largest first would give 36p = 20p + 9p + 4p + 2p + 1p, but the most efficient option is 36p = 9p + 9p + 9p + 9p

    Can anyone shed any light on this? I'd appreciate any suggestions :)

    Thanks! :)

  • Vat ID for Windows Marketplace?


    I've decided to write some apps for the new Windows Phone and to sell them on the Windows Marketplace; however, Microsoft tell me that I need a VAT ID (I'm in the UK) in order to register on the Marketplace. Does anyone know what a VAT ID is or how to register for one? I can't seem to find any useful information on the HMRC website.

    Thanks in advance! :)

  • "How I Met Your Mother" question?

    In Season 4 Episode 13 (Three Days of Snow), Ted talks about the "other ill-advised 5 word sentences every man says in his life", and one of the clips that's shown is Ted sitting on the couch saying "I'm gonna win her back!"

    I don't think I've seen this clip come into HIMYM at all, though I could be wrong - does anyone else know where this fits in? I thought maybe it would be in Season 5 Episode 21 (Twin Beds), but it wasn't.

    Just wanted to know what people thought, really!

    Thanks in advance :)

  • How does face recognition differentiate between me and a picture of me?

    Unfortunately I haven't been able to test this on my laptop yet because it isn't completely familiar with my face..but I assume that for face recognition technology to be secure it has to be able to differentiate between a person and an image (or, say, video on an iPad). How might/does it do this?

    The setup I have on my laptop uses an inbuilt webcam (single lens) to retrieve the image on which the face recognition is performed.

    Thanks in advance:)

  • Intel processor type?

    Hi, I was wondering if someone could explain the differences between the Core 2, i3, i5 an i7 processors. I'm looking to get a new laptop, and one that I particularly like, the Acer Aspire 8735G, only has a Core 2 Duo processor. I know that the Core i-series is newer than the Core 2 series, but how much difference does it really make?

    I understand that this is quite a vague question, since there are many variants of each of the processors, but any help would be appreciated.

    Thanks in advance :)

  • Electromagnetic waves and light?

    I'm not sure whether this is a stupid question or not - I just can't seem to resolve it in my head. The trouble is I also find it quite hard to word the question well.

    We've just finished a course on electromagnetism, which stems entirely from Maxwell's equations. We were able to show that there is an electromagnetic wave that carries the electromagnetic field/force. My question is: why is visible light considered an electromagnetic wave?

    It's clear enough that visible light has the same properties as the electromagnetic wave derived from Maxwell's equations, but then again, so does the gluon "wave" associated with the chromodynamic force between quarks. Why can't visible light be a completely different type of wave to the electromagnetic wave, in the same way that the gluon wave is completely different to the electromagnetic wave? Really, what makes visible light an electromagnetic wave?

    I hope I've explained that clearly enough, and I appreciate any answers anyone can give me!

    Thanks in advance :)

  • Differentiability in R^n?

    Been trying to do a bit of Analysis... was just wondering:

    I've shown that f(x)=||x||^2 is differentiable everywhere in R^n (i.e. x is a vector in R^n), but where is f(x)=||x|| differentiable in R^n, and what is its derivative?

    Thanks in advance :)

  • How much RAM for a 32-bit system?

    Hi, I've been reading up about the different aspects of a laptop so that I can get a new one. However, while 32-bit systems should theoretically support 4GB of RAM, everywhere I look seems to suggest it won't actually recognise much more than 3GB.

    So, is it worth getting 4GB then? or stick with the 3GB? If I have 3GB will it only recognise 2GB? The reason I ask is I don't understand the reason for it ignoring that last GB of ram.

    Thanks in advance :)

  • Problem with Dell laptop back-light?

    I was wondering if anyone knew what was wrong! The back-light on my Dell Inspiron 1300 laptop seems to go off every so often...and sometimes it comes back on after half a second or so, but sometimes it will last for a few minutes. I figured that this pointed to a loose connection somewhere, but does anyone know how I should find it? I was also wondering, could this be caused by a failure of the LCD inverter? Should I replace it?

    Thanks in advance :)

  • Help with an allergy problem?

    I keep getting this rash on my arms - I call it "heat rash", but really, it only occurs when it's hot and I'm in grassy areas. During the day it's ok, but in the evening and at night it becomes extremely uncomfortable, and I often have to use an ice pack to help remove the itchiness. I have tried using several different (over the counter) antihistamines, calamine lotion, sun cream and after sun cream, but nothing seems to help.

    Is there anything that anyone can suggest that will stop the itching?

    Thanks in advance :)

    The magnetic part of the Lorentz force is qv x B, but isn't the velocity 0 because neither magnet is moving? Or should I be considering the small movements of the electrons etc. inside the magnets?

  • A little bit of group theory? ...anyone?

    Let G be a finite group that has a proper subgroup H of index n (in other words, |H| = |G|/n). Show that if |G| > n! then G cannot be simple. [Hint: Let G act on the set of left cosets of H by left multiplication.]

    I've been trying this for quite a while, and I haven't got a clue how to even start it!

  • Relativistic end to the universe?

    Pretty much all astronomical bodies are moving away from us, and the further away the go, the faster the move. By Special Relativity, this means that the gravitational mass of the bodies must be increasing, and so surely this would slow the expansion of the universe - at least to a point where the expansion is constant, or maybe to a point where the universe starts pulling itself back in again?
