Why isn’t the definite article used in "The commission commanded that work [...] should cease"?
Use of "save" or "save for" in sentences Consider this picture of sun beams streaming onto the valley through the clouds.    Given that the valley is only (at a guess) 3km wide, with simple trigonometry and the angles of the beams, this gives the result that the position of the light source is being a few tens of km away at most.   What is wrong with the analysis? How can I set mouse sensitivity, not just mouse acceleration? scp from remote Linux to local Windows with spaces in local path To push a file from a Linux terminal to a Windows system, the following two examples work just fine.  scp /home/user.name/file.html user.name@local.ip.num:/C:/Users/user.name/test_folder/file.html  scp /home/user.name/file.html user.name@local.ip.num:"/C:/Users/user.name/test_folder/file.html"   I need to do this where the local folder has spaces and I cannot change the name,  say /C:/Users/user.name/test folder/  All of the following fail with the message scp: ambiguous target  scp /home/user.name/file.html user.name@local.ip.num:"/C:/Users/user.name/test folder/file.html"  scp /home/user.name/file.html user.name@local.ip.num:"/C:/Users/user.name/test\ folder/file.html"  scp /home/user.name/file.html user.name@local.ip.num:"'/C:/Users/user.name/test\ folder/file.html'"  scp /home/user.name/file.html user.name@local.ip.num:"/C:/Users/user.name/test\\ folder/file.html"  scp /home/user.name/file.html user.name@local.ip.num:"'/C:/Users/user.name/test\\ folder/file.html'"  scp /home/user.name/file.html user.name@local.ip.num:"/C:/Users/user.name/test\\\ folder/file.html"  scp /home/user.name/file.html user.name@local.ip.num:"'/C:/Users/user.name/test\\\ folder/file.html'"   How do I get this to work? Subfields of $\mathbb{Q}(\sqrt{2},\sqrt{3})$ Suppose one doesn't know any Galois theory, but they are familiar with the basic theory of field extensions. Then how would one justify the following picture?    I'm pretty sure they're just saying these are the known subfields, and there could be more but they just write down those ones (which seems weird, which is why I'm asking). Or have they deduced that this is a comprehensive list of subfields just by using basic theory? This occurs on page 573 of Dummit and Foote's Abstract Algebra. Calculate $I=\int_0^1\frac{\ln(1+x)}{1+x^2}\,dx$ How can I calculate the integral $I=\int_0^1\frac{\ln(1+x)}{1+x^2}\,dx$ by substituting $t=\frac{1-x}{1+x}$. Parse error in sudoers file Real World Example of the Strategy Pattern mkdir -p for files Updating a chart dynamically in Numbers Background: I've been having some sleep issues so I have started tracking my sleep habits along with some other data but so far, they are just entries in Evernote and as such it is not possible to see any patterns. Obviously I need a spreadsheet app with charting capabilities (doh!). I've been using a great iPhone app called  for data collection for sleep times and then enter those into Evernote.  I have the iWork set so I have been looking at Numbers and going through some tutorials but I still can't tell if it will do what I want. Given that my data set will increase daily, I'd like to be able to "page through" a chart/data set, so it shows say the last 30 data entries. With all the tutorials I have seen, the charts are of fixed size and adding more data to a linked table just causes the chart to cram more stuff in.  Can Numbers do this sort of "paging" of data? I would like to have this sort of "on the fly" charting rather than having to explicitly build a chart each time I want to visualize the data.   (sorry the question is rather garbled: I don't know really anything about using a spreadsheet type app) We just had a scenario where the enemy set up a 'death trap' with arrow slits covering a corridor, allowing them to pop in, shoot, then pop out -- all without actually entering the corridor.  Which was fine in and of itself, until my cleric ran through the corridor at top speed, with Spirit Guardians up.  The DM and I discussed it, and as far as we can tell the spell doesn't require a line of sight and isn't blocked by walls -- just being 'in range' gets you the damage.  So I wiped out an entire encounter with one well placed third level spell.  In and of itself, that doesn't seem too OP -- at level 5/6 a third level spell is a pretty big investment!  But it still seems a bit odd that I can do it without even LOS.  Are there any rules I'm missing? Primitive polynomials I am revising for a discrete mathematics exam and as quite stuck on this question.  Show that the polynomial $f = x^2 + 2 x + 3 \in \mathbb{Z}_5[x]$ is primitive. How many monic primitive quadratic polynomials are there in $\mathbb{Z}_5[x]$?  Any help would be greatly appreciated. Prevent back button after logout My flight got canceled yesterday and I am currently waiting for the delayed next flight.   Is there any website that keeps records of airlines being delayed/canceled? I would like to know my chances. I did find some sites through google (flightaware, flightstats), but they focus on us flights only and I am currently in the azores. UK Visa in an expired Nigerian passport - what to use? I am in Nigeria, my passport will expire in 4 months and I have a document to apply for a UK visiting Visa with that passport number.  Should I use it like that or go for another passport. If I choose to get another passport, how will I use it because of the passport number on the about to expired one in the document I want to use for Visa. I have a table:  table votes (     id,     user,     email,     address,     primary key(id), );   Now I want to make the columns user, email, address unique (together).  How do I do this in MySql?  Of course the example is just... an example. So please don't worry about the semantics. Can you flash any android device with "fastbood flash" command (of the adb)? I’m looking for an alien movie I watched years ago, mid to late 2000’s about the Earth being cooked or heated up by aliens. The poster is a reflection of the Earth heating up with an orange glow on an aliens eye. It was a low budget movie and I think the one I watched was pirated from China. Again low budget, bad quality and the name could’ve been something worthy he word scorch or something like that. The alien in the movie had legs with knees that went inwards and it had red eyes. LaTeX/BibTex not arranging citations by order of appearance Adverb sentence query He is arguably the best actor of his generation   In the above sentence the adverb is placed just after "be" Can we use adverb after "be"? If we can use then please explain properly because I have studied that adverb can be used before adjective and adverb .
