Coloring lines inside textarea
Sum of Cosine/Exponential Prime spectrums bijection but not homeomorphism Number after list name I'm sure this is a really simple setting I'm having trouble finding. If I delete a web part then add it again, there is a number in brackets after the title that goes up by 1 each time. How do I get rid of this? Evaluate the integral $\int \frac{\sec x}{\sqrt{3+\tan x}}dx$ Evaluate the following integral.$$\int \frac{\sec x}{\sqrt{3+\tan x}}dx$$  On putting $t=\tan x$ I am getting $$\int\frac{1}{\sqrt{(t^2+1)(t+3)}}dt$$.  How should i proceed from here. Is there a way to ignore flow errors? I have an auto launched flow that I would like to just ignore the errors of if they occur. I currently have several fault connectors going to a dummy assignment. However I keep receiving error emails which is what I am trying to avoid. Does SE have a social life/relationships questions site How to replace an old version of Ubuntu with a newer one from USB/DVD? How to convert a single char into an int Moving set of polygons in ArcGIS Pro? I am very new to mapping and I have loaded a set polygons from a shapefile into ArcGIS Pro. They appear correctly however they have clearly lost (or didn't have in the first place), their longitudinal and latitudinal information as they are currently placed in the middle of the ocean, which I believe is the 0 lat, 0 long position.  I can manually move these polygons but it won't let me save the moves, so when I click 'select', it moves back to the original location. Both of the 'save' and 'discard' buttons are greyed out and cannot be clicked. If I click 'finish' on the move tool then it will snap back to the original location too.  Does anybody have any ideas? The closest I can get to making mesh lights affect their environment in Blender Eevee is giving them an Emission material and turning on "Bloom". But this isn't emitting proper light, it just looks like it is, but it doesn't light the surroundings whatsoever.     I would like to be able to light a scene with meshes without having to put point lamps everywhere just to make them emit light. My grandparents bought a flight on United Airlines, as the one and same ticket, from Toronto, to ORD with one 55-minute layover, then to Maui. :     You won’t need to pay extra for airfare if you miss the flight, but on the other hand, you will most likely not be compensated by the airline for the incurred delay. It always depends on the amount of time, the reason for the delay and the airline’s policies. As soon as it’s weather-related, you won’t be getting a penny (and that’s normal: airlines can’t control the weather).    Yet they obviously prefer to avoid such charges from missing the 2nd flight.   Please see the titled question? Would they need to hotfoot or scamper from one gate to another, to not miss the 2nd flight? If yes to 2, can they request an airport electric shuttle cart now, before the flight? Copy-paste functionality stops working after about an hour after each reboot on a Windows 7 64-bit system. Running Google Chrome (with gmail and few other tabs open like Calendar, Reader), MS Outlook (which I don't think has anything to do with the problem — I saw it when outlook was off as well), iTunes (9.1.1.12 if it matters).  Would appreciate hints where and what for to look in a registry, and ideas for possible fix.  That is not an Internet Explorer problem (I don't even run it) — it happens in all applications.  Neither Ctrl-C/Ctrl-V nor context menu right-click Copy-Paste (actually, nothing happens on Copy, so there is nothing in a clipboard to Paste) are working. Drag-and-Drop (where supported) continues working though. Query Activity for ORDER BY xxx DESC LIMIT I'm trying to create a query activity in order to show, from a Data Extension, only the last 5 articles ids. I tried with the formula ORDER BY xxx DESC LIMIT 0,5 as in SQL but it is not working and it is returning this exception:     The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified   How can I use ORDER BY in a Data Extension? Why shouldn't I care what model/make/year my bicycle is? First Question for me.  I have benefited from other answers here but have not fully resolved my problem.  Here's my problem...  The LM311 Comparator output does not drive the N channel MOSFET fully on.  The LM311 has a 110mv ref voltage on the inverting input. The non-inverting input is driven by an opto-isolator output. The Opto-isolator is driven by 1 of 4, AC 60Hz voltages.  &lt;1VAC, 9VAC, 55VAC and 115VAC.  The goal of the design is to have the FET fully turn on the 12VDC fan when there is appreciable AC voltage.  So fan fully On for the 9, 55, and 115VAC voltages.  It seems it should work because I measure voltages on the non inverting input of 1.6, 2.2 and 3VDC respectively for the 3 appreciable AC voltages.  And my ref voltage on the inverting input is 110mv.  So it "almost" works because the fan is off at the &lt;1VAC, but not fully "On" for the other AC voltages.  I believe this is because Vgs is 167mv, 6.1V, 7.7V and 9.9 Volts for the 4 AC voltages listed above.  And the fan is only getting 7, 8 and 10VDC instead of a desired 12VDC. Would really like to be able to fully turn this FET all the way on.  So Close!  Any input or guidance is appreciated.  Ps-Things I think I've done right? Flyback diode across the fan. Putting N channel FET to switch to ground on low side of fan. LM311 has Open collector output using correctly?  PSS-I realize that the pinouts for the LM311 are not right in my schematic.  I have them right in my protoboard circuit.  Its a single device.  Pin 2 is noninveritng and pin 3 in Inverting  Thanks Again.      The suggested duplicate question and answer doesn't help for the following reasons: Both diagram and schematic are"No file found" making it pretty difficult to follow the answers. I am not using any positive feedback in my circuit as I don't think I need one. I have a simple pull up resistor to my 12V supply, not a voltage divider to the power supply as is mentioned in the answer. Thanks.  Just for the record I wanted to post a more accurate schematic and thanks for the response on using a Cap to hold up the opto isolator output. I actually have a full wave input to the phototransistor but I'm sure the cap will help anyway. To answer the last question, the Pin 7 comparator output has a pullup resistor to 12v. The issue is still that Vgs is only 10v when the comparator has 3v on pin 2 and 110mv on pin 3. I would have expected the LM311 output to go much closer to 12v (Vcc) with those inputs. The intent is for the FET to go completely on for pin 2 voltage > pin 3. How to create a folder in HOME Folder with ModelBuilder in ArcGis 10? When installing user applications, where do "best practices" suggest they be located? Occasionally I install applications manually, rather than using apt or another package manager.   What location (/usr/, /usr/local/, /opt/, /home/, etc.) is suggested by "best practices" for the installation of user applications? Is the proposal creator guaranteed moderator status? When an Area 51 site goes into public beta is the person who created the proposal one of the pro tem moderators or not?  They are talking on Area 51 about combining all the sports proposals into , including one I proposed. Would I still be one of the pro tem moderators on the merged site?  Is the proposal creator afforded any elevated status or perk? How to break out of multiple loops? Given the following code (that doesn't work):  while True:     #snip: print out current state     while True:         ok = get_input("Is this ok? (y/n)")         if ok.lower() == "y": break 2 #this doesn't work :(         if ok.lower() == "n": break     #do more processing with menus and stuff   Is there a way to make this work? Or do I have do one check to break out of the input loop, then another, more limited, check in the outside loop to break out all together if the user is satisfied? How do I get powdered mammoth tusk? Am I missing something? I can find plenty of tusks, but I just don't know if I can make them into powder myself or do I have to find them for sale?
