How to draw rectangle with Shape Digitizing toolbar in QGIS 2.10.1?
I want to draw a perfect rectangle. How can I do that with QGIS v.3+?  .  Is there a similar solution for the latest QGIS version?
How to enclosure a text block into big square brackets? everybody.  I need to enclosure a text block into big square brackets.  Something like this (I need to replicate it, more or less):   I've read that it could be possible with tikz but I don't know anything about that package.  Even, I found a code that reproduce something similar but with braces in this post:  The code is this:  \documentclass{article} \usepackage{lipsum} \usepackage[many]{tcolorbox} \usetikzlibrary{decorations.pathreplacing}  \newtcolorbox{rightbrace}{%     enhanced jigsaw,      breakable, % allow page breaks     frame hidden, % hide the default frame     overlay={%         \draw [             fill=none, % fill paper             decoration={brace,amplitude=0.5em},             decorate,             ultra thick,             gray,         ]         % right line         (frame.north east)--(frame.south east);     },     % paragraph skips obeyed within tcolorbox     parbox=false, }  \begin{document}  \begin{itemize}     \item First line           \begin{rightbrace}             \item Second line              \item Third line, which is quite long and seemingly tedious in the extreme             \item Fourth line, which isn't as long as the third            \end{rightbrace}     \item Fifth line \end{itemize}  \begin{rightbrace}     \lipsum[1] \end{rightbrace} \lipsum[2]  \end{document}   How could I put the square brackets around a block of text? (Using tikz, tcolobox or whatever package then can be useful for it).  Thanks for your help. How to send text to Notepad in C#/Win32? I'm trying to use SendMessage to Notepad, so that I can insert written text without making Notepad the active window.  I have done something like this in the past using SendText, but that required giving Notepad focus.  Now, first I'm retrieving the Windows handle:  Process[] processes = Process.GetProcessesByName("notepad"); Console.WriteLine(processes[0].MainWindowHandle.ToString());   I've confirmed it's the right handle for Notepad, the same shown within Windows Task Manager.  [DllImport("User32.dll", EntryPoint = "SendMessage")] public static extern int SendMessage(int hWnd, int Msg, int wParam, int lParam);   From here, I haven't been able to get SendMessage to work in all my experimentation.  Am I going in the wrong direction? Can't change mouse influence in proportional editing mode I press O and I see it change to Proportional Editing mode, but when I press G and mouse wheel down/up, or arrow keys down/up, it doesn't change the influence area.    And I am, I press G and then I tried to scroll to change influence, but it's not working.    Done this aswell and it's not working Is it wasteful to use a heating element, instead of doing useful work? Consider a computer CPU consuming electrical energy to perform calculations and consequently emitting heat.  Assumption: That a CPU consuming x Watts of power, emits the same amount of heat as an incandescent heating element which consumes the same amount of power.  The rest of the question assumes that this is true: the energy has to go somewhere, and I can't see that the outcome of the calculations counts as "somewhere".  I've long repeated the claim that "wasteful" appliances such as incandescent lightbulbs, over-full kettles, computers left running, etc. are not wasting power if we make the assumptions:   the appliance is in a room which we aim to maintain at above a certain temperature, warmer than the external temperature (cf a home in winter) the room leaks heat to the outside faster than the "wasteful" appliances emit heat. the room contains an electric heater the electric heater is regulated by a thermostat   In these circumstances, I think (?), if a light bulb produces excess heat, its only effect is to cause the thermostat to switch off sooner, so what energy you've "wasted" in the light bulb, is "saved" at the heater.  I don't think that's controversial.  But my question is:   If a CPU does useful work, and emits all the input energy as heat as a side effect But a heating element emits the same heat, without doing useful work Is it therefore wasteful to use heating elements? Is it more efficient to (for example) run  on a CPU, to get "free" computation as a side-effect of heating?   One reason to heat a room with a heating element, rather than with CPUs, is that the heating element is much cheaper to produce. But ignoring the initial cost of the hardware, would a "heater" made out of 20 CPUs, each running at full capacity and consuming 50W each, output less thermal heat than a 1KW element that does nothing else useful?  To be useful, of course, the CPUs would need to output the result of their computations, which would account for a tiny amount of energy. Let's assume that's negligible.  I'm sure there's a flaw in there somewhere; probably that the assumption above is false. What have I missed? What does a two overlapping circles symbol mean in an electrical schematic/diagram? In the datasheet for a A3503 Hall Effect Sensor, I saw a circuit diagram labeled 'Functional Block Diagram', and it shows a symbol I have not seen before. It's shown here between 3 - Output and 2 - Ground.  What is this supposed to represent?    The full datasheet is available How do I disable Aero Shake in Windows 7? I'm always accidentally minimizing most of my windows. This is really annoying. How do I disable Aero Shake? During Winter Bash, users can earn hats. But sometimes it seems that a hat was awarded even though its requirements weren't (yet) met, or vice versa.  What could be the reason for this? I've seen many people who say:     This is a HTML page.   Yet I've also seen many people who say:     This is an HTML page.   Are both usages equally correct?  Or, which is the grammatically correct one?       Possible Duplicates: I'm considering buying a solid state drive for my Unibody White MacBook 2010. The trouble is, I have no idea what to look for. What kind of connector am I looking for? (SATA?) What size? I'm told to get the kind that Apple uses so that I don't void my AppleCare warranty. What model/brand(s) would that be?

I have some plasterboard screws like this:     However, without a drill I have a job getting them into the wall. Am I safe to use normal screws on hangings that aren't going to be taking a great deal of weight? In this case it is a rack of coat hooks. Using Regex to generate Strings rather than match them Get tax deduction for expensive car expense Relativity and Galaxy Rotation Speed According to HTML specs, the select tag in HTML doesn't have a readonly attribute, only a disabled attribute. So if you want to keep the user from changing the dropdown, you have to use disabled.  The only problem is that disabled HTML form inputs don't get included in the POST / GET data.  What's the best way to emulate the readonly attribute for a select tag, and still get the POST data? How to stream a video with VLC in a LAN Help! My party isn't challenged? While I've been running my campaign, I'm starting to get stumped. I am playing with a party of four, and we recently switched from 3.5 to Pathfinder, but the problem was the same in both situations.  No matter what I throw at the party, they seem to have no problems. Even if I put them up against something that is supposed to be 'Epic' or 'overwhelming' in terms of CR, they make out just fine. The one exception to this is when I had several encounters in one day that taxed them to near death. Usually I have about two encounters a day, but that day I had four encounters, with two of them being APL+1 and the other two being APL+2, and that was challenging. But other than that nothing seems to faze them!  How can I make the game more challenging without making it harder?  Just for reference, the party is fairly standard, and low level (level 4):   Wizard (tends to resort to mind-affecting spells, or grease if the creature is immune) Cleric (heals a lot, but always has spells / healing left over) Rogue (sneak attack, of course, which is more potent in Pathfinder) Fighter (gets enlarged and in-charge'd) Convergence test of the series $\sum\sin100n$ I need to prove that $$\sum_{n=1}^{\infty} {\sin{100n}} \; \text{diverges}$$ I think the best way to do it is to show that $\lim_{n\to \infty}{\sin{100n}}\not=0$. But how do I prove it? ERROR 000212: Cannot create XY event source Failed to execute (MakeXYEventLayer)? I have a csv file that is 133mb in size and has over 1.3 million lines of data.  Each line of data has its own lat/long and I was wondering what would be the best way to display those points based off the lat/longs in ArcGIS Desktop 10 and ultimately turn it into a point shapefile?  So far I have tried the "Make XY Event Layer" tool but that keeps failing...  ERROR 000212: Cannot create XY event source Failed to execute (MakeXYEventLayer).  The csv file is properly formatted and the lat/long fields are numeric so I have no idea why it keeps crashing.  Here is what the first 2 lines of my CSV look like, the first line is what should be the header:  "LAT","LONG","CUSTOMER_MASTER_ID","STORE_NBR","TRANSACTION_DT","SKU_DIVISION_ID","SKU_DEPARTMENT_ID","SKU_CLASS_ID","SKU_CATEGORY_ID","SKU_NBR","SALES_AMT" "32.363544","-110.969778","2000000792627","2940","8/11/2010","2060","3920","5120","84021","5127866","13.99"   Any ideas?
