Reading string from input with space character? We have a few Win32 applications (coded in Delphi 2006) where sometimes the user gets an error message saying "System Error. Code: 8. Not enough storage is available to process this command.".  From the stacktrace it looks like it is always during CreateWnd call  Main ($1edc): 004146cc +070 app.exe SysUtils               RaiseLastOSError 00414655 +005 app.exe SysUtils               RaiseLastOSError 004ce44c +130 app.exe Controls               TWinControl.CreateWnd 00535a72 +022 app.exe cxControls             TcxControl.CreateWnd 004ce82a +016 app.exe Controls               TWinControl.CreateHandle 00553d21 +005 app.exe cxContainer            TcxContainer.CreateHandle 00586ef1 +005 app.exe cxEdit                 TcxCustomEdit.CreateHandle 005c331d +005 app.exe cxDropDownEdit         TcxCustomDropDownEdit.CreateHandle 004ceaf0 +074 app.exe Controls               TWinControl.UpdateShowing 004ceb1e +0a2 app.exe Controls               TWinControl.UpdateShowing 004cebdc +03c app.exe Controls               TWinControl.UpdateControlState 004d118a +026 app.exe Controls               TWinControl.CMVisibleChanged 004cb713 +2bb app.exe Controls               TControl.WndProc 004cf569 +499 app.exe Controls               TWinControl.WndProc 004b727d +4c1 app.exe Forms                  TCustomForm.WndProc 004cb3a0 +024 app.exe Controls               TControl.Perform 004c9f6a +026 app.exe Controls               TControl.SetVisible 004b6c46 +03a app.exe Forms                  TCustomForm.SetVisible 004baf1b +007 app.exe Forms                  TCustomForm.Show 004bb151 +14d app.exe Forms                  TCustomForm.ShowModal 007869c7 +0d3 app.exe UfrmPrice      770 +19 TfrmPrice.EditPrice 0078655d +009 app.exe UfrmPrice      628  +0 TfrmPrice.actNewBidExecute 00431ce7 +00f app.exe Classes                TBasicAction.Execute 004c2cb5 +031 app.exe ActnList               TContainedAction.Execute 004c397c +050 app.exe ActnList               TCustomAction.Execute 00431bb3 +013 app.exe Classes                TBasicActionLink.Execute 004af384 +090 app.exe Menus                  TMenuItem.Click 004b059f +013 app.exe Menus                  TMenu.DispatchCommand 004b16fe +082 app.exe Menus                  TPopupList.WndProc 004b164d +01d app.exe Menus                  TPopupList.MainWndProc 004329a8 +014 app.exe Classes                StdWndProc 7e4196b2 +00a USER32.dll                     DispatchMessageA 004bea60 +0fc app.exe Forms                  TApplication.ProcessMessage 004bea9a +00a app.exe Forms                  TApplication.HandleMessage 004becba +096 app.exe Forms                  TApplication.Run 008482c5 +215 app.exe AppName        129 +42 initialization   I've never been able to get to the bottom of what causes this and as it happens fairly seldom I haven't been to concerned, but I would like to find out what causes it and hopefully rectify it...  EDIT: Full Stacktrace  EDIT 2: More info... The client who experienced this today has had my app installed for about 4 months and it is running on his PC 8 hours a day. The problem only appeared today and kept reappearing even though he killed my app and restarted it. None of the other apps on his system behaved strangely. After a reboot the problem goes away completely. Does this point towards the heap shortage that Steve mentions?  EDIT 3: Interesting msdn blog post  and  on the topic of the desktop heap. Though I'm not sure whether this is the cause of the problem it certainly looks likely. Sorry to start a subjective question, but want to understand "own.sty" file.  Other than all \usepackage{} what sort of other commands can be added to the makeyourown.sty file.  Can you include \let command, and \newcommands in it.   What sort of precaution / structure newbies should follow. Shouldn't rep gains from old questions & answers eventually stop (or at-least reduce)? What methods can I use to create balance and consistency between a group of differing logos? A regular challenge that I face is balancing two (or more) logos. Whether they need to be equal or one needs to be given priority. Some logos however might be squares, others rectangles, circles, etc...   As a quick sample I snagged a nice high resolution photo from  and pretend its going to be an advertisement that needs to show some footwear brand logos on it. In this case I used Adidas and Saucony.  This is certainly not balanced even though they're height is the same:    Likewise this is not balanced even though they're width is the same:    So then the question becomes when are they in balance, is this balance:    Maybe a little more adjustment, is this balance:    And in these examples I'm only working with two Black Logos. Factor in color and it can get even more difficult to balance. Another issue being when there's tiny text as part of the logo.  So the question is, other than estimating / eye-balling it, what tips, methods or even tools are there to balance different sized logos? Seriously, it was fun and all, but I can't and I don't want to stay married to the same woman for the rest of my life - one real life marriage is enough..  Is there a lawyer or process of some kind in the world of Skyrim, and if not, who could help me divorce her?  If all else should fail, (sigh), do I have to take her to the backyard, thwack her head with the shovel and dig a shallow grave? How to check that a cubic polynomial is irreducible? I want to argue that argue that $\pi(\alpha)=\alpha^3+3\alpha+3$ is an irreducible polynomial over the finite field with 5 elements $\mathbb{F}_5$. My approach was just to check that $\pi$ has no roots in $\mathbb{F}_5$. Is this right? How to rig a shirt with buttons so that the buttons follow the mesh of the shirt I didn't address this in a while because I was busy with something else, but now it has cycled back into my schedule.  Right now I have a shirt modeled and bones set in place. It's already technically rigged, but the only issue is the buttons.   I'm not entirely sure how to go about connecting them to the shirt's deformations. I tried to combine them and the shirt into one object, but because of the shirt's modifiers, (Solidify and subsurf, which I don't want to apply yet), the buttons become extremely deformed. I've tried to match the weight painting intensity where a button is at in correspondence with the shirt, but that doesn't seem to work, maybe it has to do with the specifics of where the button is?   Is there a way to make the buttons follow the shirt's deformations without deforming the mesh vertices of the button? I know that if I probably apply the modifiers on the shirt and combine it with the buttons, it would be okay, but I'm not okay with doing that just yet with the shirt.    I rigged the shirt by deleting all vertex groups, assigning empty groups to the mesh from the armature, and then assigned automatic groups in the weight paint menu.  Is there a way to do this? Is it possible to view Google Chrome bookmarks and history from the terminal Is it possible to view Google Chrome bookmarks and history by using command line? Alternative to LibreOffice Base for Ubuntu if $x_i$ are IID  continuous random variables, with $E[x_i]=μ$, is the following correct?   $E\left[\prod_{i=1}^n(1+⍺\space x_i)^i\right] = \prod_{i=1}^nE\left[(1+⍺\space x_i)^i\right] =  \prod_{i=1}^n(1+⍺\space E\left[x_i\right])^i = (1+⍺\space μ)^n$  thanks! I'm looking for the name of a sci-fi series, intended for children. Robots have control over the humans. There is a squad of humans who attack them. Every member in this squad has a badge on their suit, and when they touch this badge the suit becomes armed. This series was not cartoon series, it was performed by real people. The main robot character is very similar in style to Darth Vader in Star Wars. The series aired in the 1990s. I am sorry but I can't recall many details. What is the location of lock screen images on Windows 10? Where, or what format, are the images used by Windows 10 when logged out or in lock-screen?  I searched the entire drive for *.jpg, *.bmp, *.png, and *.tif but the one I was looking for did not appear.  At first glance, , although not exactly a duplicate, appeared to have the path I wanted.  But when I went there, the pre-login image was there, but the lock-screen image was not.  (And contrary to the claim in that answer, the files there did have extensions.)  UPDATE: I just did a lockscreen, and got an image that IS in that directory, but earlier today, it was consistently an image of an interesting footbridge that is not in that directory. Do electrons move around a circuit? We could imagine a simple electronic circuit composed by a power source and a resistor.   It is usual find descriptions as "The moving charged particles in an electric current are called charge carriers. In metals, one or more electrons from each atom are loosely bound to the atom, and can move freely about within the metal. These conduction electrons are the charge carriers in metal conductors." (wikipedia ). That made me imagine electrons going from power -, running by the wires, crossing the resistor and returning to power +, where they suffer a new kick to power -. All that at near the speed of light.  In this model, it is easy to define "electrical current intensity" as proportional to the number of electrons per second that cross one specific point of the circuit.  However, looking for the physics of resistivity, I can read the phrase "The actual drift velocity of electrons is very small, in the order of magnitude of a meter per hour." (wikipedia ). This is a complete different point of view, where electrons are more or less fixed around a fixed position (or moving very slowly), an electricity is a wave of "collisions" or "jumps" of electrons, like in a Newton's cradle (or "do the wave" as public in a football match). Obviously, we do not need severals hours from the switch on to the light on.  So, the question is, do electrons move around a circuit ? References to band theory are welcome.  A related question is: if electrons doesn't moves along the circuit, what is "electrical current intensity"?  Note: I known there are similar questions already posted, but answers of the ones I've read are not very detailed (could be I've not found the best ones). Please, be a few patient before "close vote". Frequent Write to Non-volatile Memory I am designing a device that automatically adjusts it's physical position as temperature changes. If the device it shut off or power is disconnected the device needs to remember it's last temperature and position. I have the ability to store these values in EEPROM but the problem is the position and temperature could be changing very rapidly. If I were to write the temp and pos to EEPROM after every time they changed that would (1) slow down the firmware a bit, and (2) likely kill the EEPROM after a year or two. So as I see it my options are as follows...  1) use a capacitor/battery to keep the device powered for a short time after power is lost so that I can write the values to EEPROM at that time only. I don't like this because the board is kinda power hungry and this would require a big cap. And I don't have a ton of free space. And I don't want the added cost of a battery and battery holder / or a big cap.  2) use F-RAM instead of EEPROM so that I can write to it trillions of times without wearing it out. I don't like this option because FRAM is quite a bit more expensive than EEPROM and this is for a production product (not just one).  3) Only write the position and temperature every 5 minutes or so. That way I always have a fairly recent position/temp recorded but I am not writing every second so my program is not slowed down and the EEPROM won't die as fast. This seems like my best option.  Does anyone else have any suggestions that I'm not thinking of? Proving $1-\exp(-4x^2/ \pi) \ge \text{erf}(x)^2$ This is a follow-up to  question. I came across a tighter potential bound and checked it numerically for $0\le x\le 5$. I think it holds for all positive $x$, can anyone see a proof?  $$1-\exp(-4x^2/ \pi) \ge \text{erf}(x)^2$$  Note: using analysis for previous  you can show that $1-\exp(-k x^2)$ is an upper bound on $\text{erf}(x)^2$ for $k=2$ and a lower bound when $k=1$. The factor $k=4/\pi$ comes out when numerically searching for tightest upper bound. Not only does it seem to give an upper bound, but it also tracks $\text{erf}(x)^2$ very closely.  Dashed graph below is $\text{erf}(x)^2$, red is $1-\exp(-k x^2)$ for $k=4/\pi$, other two graphs are for $k=1$ and $k=2$ Will be glad for a little hint: let x and n be positive integer such that $1+x+x^2+\dots+x^{n-1}$ is a prime number then show that n is prime Find coefficient of $x^{50}$ in $(\sum_{i=1}^{\infty}x^n)^3$ When is the image of a linear operator (between Banach spaces) closed? Short story about humans serving as hosts to the larval stage of insects I read this story in a sci-fi paperback magazine probably in the 1970s or 1980s, but it might have been published much earlier.  It begins with a conversation between two young men (brothers?), the older of whom, it eventually transpires, has taken the place of the younger in serving as a host to insect-type creatures.  The insect-types are the main form of life on the planet, and use the human interlopers/colonizers as hosts for the larval stages of their    young. Must have pre-dated the &quot;Alien&quot; movies because when I read it the idea of humans serving as larval hosts was new to me. Don't remember how the story ends -- whether the emergence of the larva kills the human host.
