How can I recover data from lost and found files present on root.disc from Windows? After changing size of Ubuntu folder (the command I used was dd, folder loop0) the kernel panicked, my Ubuntu is dead and I cannot recover it with GRUB or any recover tool (vmlinuz is not even present).  Is it possible to recover files from Ubuntu's partition while I am logged into a Windows system? I have some program to open Ubuntu's root.disc, but only "lost and found" files are listed there.
Possibility of recovering files from a dd zero-filled hard disk I have "zero filled" (complete wiped) an external hard disk using dd, and from what I have heard: people said you should at least "zero fill" 3 times to be sure that the data are really wiped and no one can recover anything.  So I decided to scan the disk once again after I've zero filled the disk. I was expecting the disk to still have some random binary left. It turned out that it has only a few sequential bytes in the very beginning. This is probably the file structure type and other headers stuff. Other than that, it's all zeros and nothing else.  So if we have to recover any file from a zero filled disk, ...how? From what I've heard, even you zero fill the disk, you should still have some data left. ...or could dd really completely annihilate all data?

Do not allow giving minus one for new user questions I always see Stack Overflow users giving -1 to new users' questions. This is not how you welcome a new user to the community. A new user does not know the rules yet.    I suggest that if one wants to give -1 to a new user, you prevent that and ask the downvoter to write a comment instead. new user = 2 first questions    I see the credit rating on my question is now at -9?  My question, is she not well formed or formatted? If you don't agree with the content of a question do you down-rate it? If an Ubuntu user asks a question that might not be reasonable, will you also down-rate it?  No. You post an answer that will present your thinking and correct him? I think that is part of the problem. When you first go to a community like Facebook, and you don't know the faces, you don't feel like any of those people are your relations. Newbies exist here as well, especially in a professional community.    First, welcome the new user in more appropriate way. And most importantly, force them to see/read how to post a good question. I want to include some Cyrillic with a TeX Gyre Pagella text and math font document. I'm using TeXLive 2019.  As indicated in , running pdflatex on the following source works just fine:  \documentclass{article}  \usepackage[T1,T2A]{fontenc} \usepackage[russian,main=english]{babel} \usepackage{paratype} \usepackage{tgpagella} \usepackage{substitutefont} \substitutefont{T2A}{\rmdefault}{PTSerif-TLF}  \usepackage{amsmath}  \usepackage[math]{blindtext}  \begin{document}  The topologist is {\Russian Алекс\'{а}ндров}.  \blindmathpaper  \end{document}   However, running xelatex on the following surce produces output from which the indicated Cyrillic just disappears:  \documentclass{article}  \usepackage[T2A,T1]{fontenc} \usepackage[russian,main=english]{babel} \usepackage{amsmath} % load here to avoid \dddot clash \usepackage{fontspec} \usepackage{paratype} \setmainfont[Ligatures=TeX]{TeX Gyre Pagella} \usepackage{substitutefont}% \substitutefont{T2A}{\rmdefault}{PTSerif-TLF}%  \usepackage{unicode-math} \setmathfont{TeX Gyre Pagella Math}  \usepackage[math]{blindtext}  \begin{document}  The topologist is {\Russian Алекс\'{а}ндров}.  \blindmathpaper  \end{document}   Question: How should this second source be fixed so as to allow the Cyrillic to appear, too?

ASP.NET MVC 3 localization with DisplayAttribute and custom resource provider This has come up    : migrating old questions causes problems.   The most popular solution to this to date has been to . This is do-able, but frankly it feels like treating a symptom, and doing so in a way that penalizes folks who answer what are by all appearances valid, on-topic questions.   Migration works best as a way to salvage good but off-topic questions and give them new life on a site where they can thrive. But shuffling old, answered, on-topic questions around for the hell of it is a waste of everyone's time.   Therefore, I think the real solution is much simpler: just disable the migration of old questions. They're rarely welcomed or heavily improved post-migration, often overtly disliked by folks on the destination site, and can end up causing a rather bad experience for folks who were participating in good faith on the original.   I suggest that questions older than 601 days should not be eligible for migration, either by normal user close-votes or by moderators. In extreme cases, we can perhaps provide an alternate means of moving old questions, but under normal circumstances these should be done quickly or not at all.   1 60 days is actually based on a  introduced this past spring: migrated and then rejected questions older than 60 days cause the authors to suddenly gain (permanent) reputation on the destination.

After the upgrade I can't figure out how the new shield system works. I have the option to discard the shield, and I notice I have a new potion in the inventory.

Constants of integration in integration by parts How can I know if my post(comment, answer, question) was Flagged? Is it possible to see if my post was flagged. The only way as I see it, if you see your post has got deleted, them may be someone might have flagged it for moderation. But is there other way to see if your post was flagged for moderation.   I am wondering if someone's is repeatedly flagged for posts, maybe he can be assigned a badge(bad one :) )  But right now, I want to know if it is possible to see how many posts of mine were flagged. Number theory proof mod p For a given prime $p$ and integer $k$,  $k∈&lt;1, p-1&gt;$ $S(k)$ is defined as a sum of remainders of $k, k^2, k^3, ..., k^{p-1}$ when divided by $p$. Prove that $S(k)=\frac{1}{2}p(p-1)$ is true for an odd number of different k. I managed to prove that $S(p-1)=\frac{1}{2}p(p-1)$ but can't see how to do it further.
