Difference between "offense" and "offence"
Is there any difference between "offense" and "offence"?
Let $R$ be a commutative ring with 1 then why does $a\in N(R) \Rightarrow 1+a\in U(R)$? How can I check for an empty/undefined/null string in JavaScript? Objects stuck in solid mode? I can't figure out what is causing this I tried removing the materials for the objects as well as re-assigning new materials and flipping normals I don't know what is causing this issue for the model.  The head seems to be working like it should but the body doesn't turn white in textured mode or black in material mode. I'm using default blender render Data Recovery - How to Restore Deleted / Formatted Files on HD Micro SD Card Background:    I put in a friend's SD Card to format it because it was having problems. Then I put mine back in and I think my phone formatted my SD Card. I had a ton of pictures on there that are now gone! I put the card into the computer and there's only 2mb of cache files on there and none of the original directories.   I already tried the following freeware recovery applications:         Neither of them were able to retrieve any files. Undelete took 1minute to scan for files and came up with 0 files.  Recuva took 10 minutes for their "deep scan" which doesn't seem thorough enough at all for this 8GB SD Card. I need something that's a lot more heavy duty.  I don't mind paying for an application to get the data back if necessary...   Questions:     Which application can I use to recover my deleted picture files from my 8GB HD Micro SD Card?   Why did Anroid format my SD card?   How can I tell if it's a phone problem, data problem, or SD Card problem? How to generate a random integer number from within a range Superman has been exploited by Poison Ivy in Hush, and he's definitely mad in Injustice. What about Batman? Has Batman ever had to be brought to justice/stopped/killed by his fellow superheroes? (That one time when Superman dreams of Batman snapping Joker's neck doesn't count)  Edit: The Dark Knight Returns doesn't count: Batman wasn't really mad, and he wasn't wrong either. Does deleting iCloud photos affect them on devices? If I delete a photo from my iCloud will it also be removed from my devices that are connected to my account? How long would the conference be for? I want to know if this is grammatically correct " How long would the conference be for?". If one uses Shadow Evocation on a willing ally (e.g. Telekinetic Charge) can they choose not to disbelieve? Shadow Evocation  Nondamaging effects have normal effects except against those who disbelieve them. Against disbelievers, they have no effect.  Disbelief  Creatures encountering an illusion usually do not receive saving throws to recognize it as illusory until they study it carefully or interact with it in some fashion. A successful saving throw against an illusion reveals it to be false, but a figment or phantasm remains as a translucent outline. A failed saving throw indicates that a character fails to notice something is amiss. A character faced with proof that an illusion isn't real needs no saving throw. If any viewer successfully disbelieves an illusion and communicates this fact to others, each such viewer gains a saving throw with a +4 bonus.  (my emphasis) Voluntarily Giving up a Saving Throw  A creature can voluntarily forego a saving throw and willingly accept a spell's result. Even a character with a special resistance to magic can suppress this quality.  If I understand the above correctly,  If the ally believes the caster actually cast Telekinetic Charge, it seems they get a save which they could forgoe and so be guaranteed the benefit of the spell. &gt;&gt; We're good here. If the ally knows the caster didn't cast Telekinetic Charge, (say because of a high Spellcraft check or because she knows the caster's spell list) they have proof that the illusion isn't real and so need no saving throw. &gt;&gt; Even though she &quot;needs no saving throw&quot;, can she still choose to forego the save and be effected by the spell?  In other words, I think the question boils down to: Does one always have a choice not disbelieve an illusion, even when one has proof that it's not real? How to implement a tree data-structure in Java? Give an example of a convergent series $$\sum_{n=1}^{\infty}a_n$$ such that the series $$\sum_{n=1}^{\infty}a_{3n}$$ is divergent..  I cannot find find any kind of series... I am also be very thankful if you find a divergent series (changing the term convergent)... Restore open applications, documents, and window state When working on a project, I generally have a couple of Explorer windows open to relevant folders and a couple of applications (e.g. Eclipse and a form development tool) open to specific project-related documents.  There's a lot of value in that context, and I'd like to find a way to save a set of open apps under a project name, then restore that state at a later date.    Thus far all of the utilities I've found are virtual desktop products that don't save/restore state.  I'm specifically looking for something that will run the applications I had running, open the documents I had open, and position the windows as they were.  I'm amazed that such a seemingly simple concept as "Save my workspace state" doesn't seem to be available.  I'm on Windows 7.  Any suggestions? How to hide title bar in Firefox 57 Quantum? I used to use an extension to hide/show the title bar in Firefox, but since Firefox 57 was released most of the extensions were disabled.  In Chrome I just uncheck the option "Use system title bar and borders" and it's done.  Are there any ways to do that? There are many collectable flags throughout the game of Assassin's Creed and every time one is collected, you get a progress indicator (e.g., 33 of 100).  Is there any reason to collect these, other than bragging rights?  I recall getting all available flags in one particular town and never saw any special reward or secret revealed. Greek pdf bookmarks I am puzzled with sections titled with Greek characters. They do appear in the pdf's Content list, though not correctly.  For example, in my thesis--written in English with LyX, based on the KOMA-script--I choose to include a translation of the summary in Greek (=Περίληψη). The "raw" code for the (unnumbered) chapter title reads: \addchap{\textgreek{Per\char208lhyh}}. In the final .pdf file (using pdflatex) the respective entry appears as Per208lhyh. Using the unicode option for the hyperref package does not fix the problem.  Update detail: the document (should) not only contain Chapter or Section titles in Greek, but normal text as well.  I have found some relevant references within tex.stackexchange and elsewhere (e.g., , the manual of the textgreek package, , ). However, I cannot extract a concrete answer.  How can Greek characters appear correctly as bookmarks in the .pdf's Content list?  Note, the information of this Q&amp;A applies to/under LyX as well. What causes the expansion of space? Pass shell variable as a /pattern/ to awk Is it possible for reviewers to mistakenly reject a quality paper? How do I integrate the following $$\int \frac{dx}{\sin^3 x + \cos^3 x}$$ ?  It appears that I am supposed to break this up into $(\sin x + \cos x)(1-\cos x \sin x)$, but the next thing to do is not apparent to me. Add parenthesis as an accepted Markdown ordered list delimiter The Markdown editor knows that an empty line, followed by a number, followed by a period, followed by a space, is a list item.  This works great It's almost magic  The problem is that I almost always use a close parenthesis for my lists. I think it's a pretty common practice, but the problem is that the editor / Markdown parser doesn't accept parenthesis as an acceptable list delimiter:  This fails horribly This is on the next line I swear
