I found my laptop from 6 years ago that my partner installed your operating system on. I have no idea what the password is. I have attempted to change it in recovery but when I try to type in a new password it wont let my type anything. I can press enter but it continues to say; 'Authentication token manipulation error' and ' password unchanged'.  I am not amazingly tech savvy, i know how to find and fix alot of problems but this type of stuff... ive done everything I could think of.  Can anybody help me?
I'm working on a Ubuntu system, and my client has completely forgotten his administrative password. He doesn't even remember entering one; however it is there.  I've tried the suggestions on the website, and I have been unsuccessful in deleting the password so that I can download applets required for running some files. Is there a solution?
There is an alignment issue in the stackexchange.com search page .  The bottom bar is missing in the search input box.  Sample URL:   Screen shot for reference:    Firefox version: 54.0b8 (32-bit) OS Version: Windows 10 Pro  Also happens with Chrome latest version. Is there a test for the different styles within maths mode?  What I really want is to be able to save the current style to reinvoke it later on, but a \if along the lines of \ifmmode would work just as well.  In the specific example, I want to measure how big something will be when displayed in maths mode, so I do:  \settoheight{\mathheight}{some bit of maths}   except that it complains because the some bit of maths gets put in a box and measured, and the box doesn't know that it's maths.  So instead I put:  \settoheight{\mathheight}{\(some bit of maths\)}   except that then I get the wrong answer if this is used in displayed maths.  So ideally, I want:  \ifdisplaystyle  \let\currentstyle\displaystyle \else  \iftextstyle   \let\currentstyle\textstyle  ...  \fi \fi \settoheight{\mathheight}{\(\currentstyle some bit of maths\)}   and then I'll be happy.  Is there such a test?    Okay, so \mathchoice is clearly the way to go (thanks Martin!), but its behaviour is a little odd and since I want to use it to define a macro depending on which mode I'm in, this oddity is quite important.  Here's the code:  \newcommand{\mathtest}{% \gdef\name{a}% \mathchoice{% \name \gdef\name{b}% }{% \name \gdef\name{c}% }{% \name \gdef\name{d}% }{% \name \gdef\name{e}% }% \name}  \[ \mathtest \]   If \mathchoice behaved like \if, this ought to print ab.  But it prints ae.  All the options to \mathchoice get processed (which makes me wonder a bit how it works, but that's by-the-by).  So, is there an obvious way to make \mathchoice behave a little more like \if? Vertically align horizontal inline-block elements Is MacBook Pro warming during gaming normal? I have a 2010 MacBook Pro MC371 (Core i5, GeForce 320M, 4Gb RAM).   When I launch a game either new one (i.e. Starcraft 2) or rather old (Unreal Tournament 2004, bootcamped) my MacBook gets rather warm, even hot in the top left corner, around the place where magsafe charger is plugged in. The temperature is more than 40C. The fact that confuses me is that this warming occures even when I play old games.  Is that OK? "Add/show 1 other comment" bug strikes again I noticed that my American friends tend to use the past perfect form when they use the verb mention in its past form, almost despite of the context of the sentence. I hear them say  "you had mentioned" a lot more often even in situations where the use of simple past would have been perfectly fine. Have you noticed it too and is it one of those unwritten rules, or is there a more formal explanation to it?  It seems like there was more verbs like that, but I am having a hard time remembering it now. If I do, I will edit the post and likely change the title to accommodate other verbs. Input string was not in a correct format Is there a criterion to differentiate "thriller" from "horror"? After installing Windows 10 on my  it took my user name 'Jeremy' and created a user folder named C:\Users\jerem.  I want to rename the folder C:\Users\Jeremy.  does not work. There are a couple of reasons.   OneDrive is now a fully integrated part of the OS, and it completely breaks.  A find/replace in the registry seems to work, but it's hard to be confident in that approach. When the computer is rebooted, the TabletInputService writes a TextHarvester.dat file to the old user profile location (creating it if needed). This makes it impossible to keep the folder deleted. An old  doesn't work. This issue also causes an error message to pop up every time the computer boots. Many spells have "At higher levels" that provides for more targets or more damage.  For example Magic Missile can be cast as a second level spell and shoot 4 missiles instead of it's 3 as a first level spell.  Can a spell without that verbiage, such as Firestorm be cast in higher level slots for the same effect as the lower level spell? Is the product of two non-holomorphic function always non-holomorphic? Suppose $h(z)$ is a complex function. I have noticed that $h(z) = f(z)\cdot g(z)$, where $f(z)$ and $g(z)$ are non-holomorphic. Can $h(z)$ be holomorphic?   Can a similar statement be made, if $f(z)$ is holomorphic, but $g(z)$ is not? Custom thumbnailers don’t work on Ubuntu 18.10 and 18.04 Recently I had a bunch of my own scripts for the thumbnails in Nautilus: , , office documents and so on.  Seems like either I’m doing something wrong (thumbnail generation behavior changed), or custom thumbnailes don’t work in latest GNOME at all, even my previous scripts, which worked smoothly on previous versions of Ubuntu.  I’ve done some research, tried to run a simple script (see below) and it didn’t work out.  My test thumbnailer in /usr/share/thumbnailers/z.thumbnailer:  [Thumbnailer Entry] Exec=/home/maximal/thumb.sh %s %i %u %o MimeType=image/webp;image/x-webp   Where /home/maximal/thumb.sh is:  #!/bin/bash echo $0 &gt;&gt; /home/maximal/thumb.log echo $1 &gt;&gt; /home/maximal/thumb.log echo $2 &gt;&gt; /home/maximal/thumb.log echo $3 &gt;&gt; /home/maximal/thumb.log echo $4 &gt;&gt; /home/maximal/thumb.log   Then, when I remove thumbnail cache rm -rf ~/.cache/thumbnails and restart Nautilus nautilus -q, my log file doesn’t contain anything and ~/.cache/thumbnails/fail/gnome-thumbnail-factory contains all the failed thumbs (looks like corrupted/empty PNGs):    So, apparently, Nautilus even didn’t try to execute my thumbnailer script. When I try to run thumb command itself, it works perfectly. For example convert through cwebp|dwebp package:  convert -thumbnail 256x256 file.webp png:file.webp.png   When I wrap this command to a thumbnailer, it looks like it wasn’t even requested to run by Nautilus.  [Thumbnailer Entry] Exec=convert -thumbnail %sx%s %i png:%o MimeType=image/webp;image/x-webp;   Exactly the same situation occurs with other my thumbnailers: audio waveforms, office documents, photoshop files and so on.

I created a field called bg_image and attached it to the standard plain page.  After fiddling around for hours I was able to get the Image URL in node.html.twig  {{ file_url(node.field_bg_image.0.entity.uri.value) }}   but I could not get it to work inside field--field-bg_image.html.twig  Can I get the node from there anyhow, so I can then get the image?  How can I get the image URL to use as inline style? I thought maybe I can pass a variable from field--field-bg_image.html.twig to image.html.twig and then just render  {{ uri }}   instead of  &lt;img{{ attributes.addClass(classes) }} /&gt;   but I could not get it to pass the variable there unless I use includes  {% include 'image.html.twig' with {'image': image, 'isFromField': isFromField} %}   (isFromField is true, when it comes from the field--field-bg_image.html.twig) But that didn't work either. The Image was never rendered that way.  Would be very glad if you can help - my php knowledge is very basic. Thanks Is there a saying or idiom for "trying to get the truth from someone by lying"? context   Mary-Ann got home late from school.  Asked where she had been, she said she had spent the afternoon at the library.  Her father thinks she is lying and says: "I know you haven’t been there because I was there myself".  He is lying because he thinks she will tell the truth if she realizes she has been caught. boyfriend – “your sister told me everything” (sister did nothing) -  girlfriend – “Oh, did she? I’m gonna kill her.    The rationale for doing this is to catch someone by surprise so he will admit having lied.  Soemtimes, however, the person isn’t lying and the real liar will have to reap the consequences of his reproachable action, having to admit he was just/it was just ...........(saying or idiom).....
