So I just ordered a new phone (Honor 5x) I need to know can I install an early version of Nougat &amp; when its released will it operate on my phone? Thanks!
Android Nougat .  It adds features such as multi-window support.  You can review the high-level changes at .  Of course, not all devices will get this update right away, even at release; others won't get it at all. Manufacturers and carriers often choose to add their own custom modifications, which tend to delay the official release.  When will each device get Nougat, either officially or unofficially, if ever?  See also:
Negation in English Maximize the product of the partitions of an integer Description list with aligned descriptions is exactly what I'm looking for. I want my description environment to produce this:  Label is long   text  lab2            blalballalaa label3          possible second rule label four      hello world   Someone offered this:  \newenvironment{mydescription}[1]                                                   {\begin{list}{}%    {\renewcommand\makelabel[1]{##1:\hfill}%    \settowidth\labelwidth{\makelabel{#1}}%    \setlength\leftmargin{\labelwidth}    \addtolength\leftmargin{\labelsep}}}   {\end{list}}   Which works great (the parameter is the longest label), except I think the enumitem should be able to do this. Unfortunately, the documentation for it is extremely confusing to me. Could someone show me how to achieve the same result with enumitem? $A$ is an $n\times n$ matrix of complex numbers. Prove that if $\lambda$ is an eigenvalue of $A^2,$ then $\sqrt{\lambda}$ or $-\sqrt{\lambda}$ is an eigenvalue of $A.$    If $\lambda$ is an eigenvalue of $A^2,$ we have $\lambda\alpha=A^2\alpha$ for some $\alpha.$ Then how can we find a $\beta$ s.t. $\sqrt{\lambda}\beta=A\beta?$ Declare global variables in Visual Studio 2010 and VB.NET The vote fraud script breaks legitimate polling questions - A serial downvoter's lament I've downvoted several of the answers on these Meta discussions:       Both questions are typical self evaluations, Stack Exchange runs them on all young Beta sites and as you may have noticed they are essentially polls, a series of example questions from the site that we are supposed to vote on.  Today I noticed that almost all of my votes have disappeared on both evaluations, only an upvote remains in the later one. My votes triggered the serial voting script, something that :      Heh, it appears I just serially downvoted you (I downvoted a lot of the answers here), hopefully the script is smart enough to not reverse my votes. Will check back in 24h, and if it does, I'll rant about it on MSO ;)    My voting behaviour on both evaluations was very simple:   I had the evaluation open in the left monitor, Opened all the example questions in their own tab, in the right monitor, Scanned each question quickly, and voted on the Meta answer (most of my votes were downvotes), Repeat for the next one, and so on...   I didn't spend more than a few seconds on any question, as I'm fairly regular on the site and I've already read all of them while casually browsing the site. In fact, if my memory isn't failing me, I had voted (up/down) and/or commented, and/or voted to close on each of the 20 example questions. I might have spend a minute or two re-reading a couple, but I mostly scanned through them. In any case I think my voting pattern is quite normal, and the script should be somehow tweaked to take serial posts, posted by the same user in quick succession, into consideration, especially on Metas.   Since I had anticipated that the script would kick in, I could have tried to fool it by pausing a bit between votes or trying to look for other Meta posts to vote on, in between voting on the evaluation answers. However I'm a very active voter on Meta Workplace, there aren't many posts I haven't already voted on, and the few that I haven't is probably because I neither agree or disagree with (my opinion on them is simply "meh"). In any case I think my voting behaviour was natural, and although the serial voting script is awesome, this time it caught and reversed a perfectly legitimate behaviour.  Animuson, in , mentions that the script isn't really optimal on Area51 as well:      Yes, please implement this on Area 51 proposals too! Oftentimes a single user would suggest a plethora of "example" questions to their own proposal which are just terrible, yet all of everyone's votes get reversed and the question just sits there at 0. I've noticed several times that my votes have gotten reversed.    I haven't noticed it myself, but it certainly seems plausible, especially early in a proposal's life.  Mysticial found a related discussion, , but it's focused on voting patterns on main sites, where reputation is also a factor. I can understand jumping through hoops to satisfy the script on main sites where, unfortunately, there are a lot of people trying to get some cheap rep or "punish" others with their downvotes, but not on Metas, and especially not on these evaluation posts.   Voting fraud is a problem, and more often than not the script works wonderfully, but in my case it was extremely counterproductive. Critical evaluations are essential for a young Beta site, and their answers typically only get a handful of votes. I wonder how many of these votes have silently gone away...  Fix this please. Discouraged by simple Bayesian Question My university is testing an intro Machine Learning (ML) course for us undergrads, and having been interested in ML since the beginning to understand what it was, I jumped at the chance to take it. But being someone who has not been back in school for a long time and much busier than I was in my first years long ago, I am finding that I need more info and examples than the class in its current form has.  I am struggling to figure out what the attached question is asking. I am searching online for help with this particular topic, but I am also finding that everyone seems to have their own way of phrasing similar questions in such a way that I am finding it hard to link the info.   My understanding from stats way back when is that $p(x|\omega_1)$ is stating the probability of $x$ given $\omega_1$ for $0\le x \le 2$ and zero other wise. Same obviously if given $\omega_2$. If I understand, the priors are the probability of $\omega_1$ and $\omega_2$ which are somehow obtained. And honestly that is as far as I am really comprehending. I am not sure what (a) and (b) are truly asking for or how to get them. If anyone is able to help me with some pointed info on the topic it would be greatly appreciated. "errno 5 - input/output error" when trying to install Ubuntu Today I downloaded Ubuntu for my laptop. It runs great from a bootable USB, but when I tried to install it, I got the following error message: The installer encountered an error copying files to the hard disk:  [Errno 5] Input/output error  This is often due to a faulty CD/DVD disk or drive, or a faulty hard    disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower   speed, to clean the CD/DVD drive lens (cleaning kits are often    available from electronics suppliers), to check whether the hard disk   is old and in need of replacement, or to move the system to a cooler   environment.     I tried everything to install it on my laptop including redownloading the Ubuntu ISO image, but nothing worked. Proof that for $a,b,c\in \mathbb{R}$, hold that $\left |\sqrt {a^2+b^2}-\sqrt {a^2+c^2} \right |\leq \left |b-c \right |$. Proof that for $a,b,c\in \mathbb{R}$, hold that $\left |\sqrt {a^2+b^2}-\sqrt {a^2+c^2}  \right |\leq \left |b-c  \right |$. Give me a clue, I don't have any idea to work with that inequality. download file on form submission I have created a form which has only a submit button. In the submit function I am generating csv file and saving it to the files folder using fputcsv function.  But Now I need extra functionality of submit. After saving the file it should download the file also.  How to do this? Any one have some idea about this? How do you serialize an object in C++? I have a small hierarchy of objects that I need to serialize and transmit via a socket connection.  I need to both serialize the object, then deserialize it based on what type it is.  Is there an easy way to do this in C++ (as there is in Java)?  Are there any C++ serialization online code samples or tutorials?  EDIT: Just to be clear, I'm looking for methods on converting an object into an array of bytes, then back into an object.  I can handle the socket transmission. How do trees lift water higher than 10 meters? The atmosphere pressure is 10 meters of water (approx). This means that it is impossible to lift water higher than 10 meters with vacuum or сapillary action (on Earth, under normal conditions).  There are trees higher than 10 meters.  How do they lift water to their tops?  UPDATE  In other words: how cohesion-tension theory can be true if it apparently contradicts the laws of physics?   UPDATE 2  Atmospheric pressure helps to rise the water, not resists rising. What is resisting is water weight. When water column is 10 meters high, then atmospheric pressure can't help anymore.   Any adhesion/cohesion mechanism can't help here too, because it acts only in thin molecular layer. To transfer action force further the pressure is required, which is insufficient at 10 meters.  UPDATE 3  If we had capillary small enough to rise water to 10 meters and then we will build smaller capillary which we expect will rise water higher, we will fail. Water column will break and does not climb higher than 10 meters.     Menisci acts like small piston and can't help rising water higher than 10 meters.  UPDATE 4  Common pressure distribution in capillary is follows:    $P_0$ is atmospheric pressure. As you see, right under menisci, the pressure is lowered by $2 \sigma / R$ where $R$ is the radius of menisci and $\sigma$ is surface tension. The entire term is called "Laplace pressure". As you see, it can't supersede atmospheric pressure, because water continuity will be broken in the case.  I.e. no any menisci can rise water higher than 10 meters.  The existence of higher trees PROVES that there are some other significant mechanisms, not adhesion/cohesion, not capillary.  UPDATE 5  Current version, as I understood it, is based on a declaration, that a water, if put into thin capillary, can behave like a solid body. Particularly, it can resist tension up to minus 15 atmospheres.   This is a tensile strength of concrete, so I don't believe that without additional proofs.  I think it is just not hard to make thin tube, put water into it and check, how high it can climb.  Was it done ever? I'm building an application where I should capture several values and build a text with them: Name, Age, etc.   The output will be a plain text into a TextBox.  I am trying to make those information appear in kind of columns, therefore I am trying to separate them with tab to make it clearer.  For example, instead of having:  Ann 26 Sarah 29 Paul 45   I would like it to show as:  Ann tab 26 Sarah tab 29 Paul tab 45  Any tip on how to insert the tabs into my text? How can I install Windows software or games? G-test vs Pearson's chi-squared test What is the origin of the word  as in the interjection:     — It's hot in the desert.   — Well, duh!   If it is of onomatopoeic origin and only appears in modern English as some sites suggest, I would be interested to know when it started appearing in English writing. How does one prove that every finite group is isomorphic to a subgroup of an alternating group? I have asked this question before ( and  )  My problem is that my Self Encrypted Disk (SED) have to NOT spin down even on suspend!  I have tried , but it did not work and the disk spin downs anyway !  The problem is that if the disk spins down, because it is on suspend, it does not show the "de encryption" prompt, and boots back up on RAM, but crashed due to IO error on the disk! (that's what the disk is suposed to do !)  Anyone on how to NOT (as in NEVER) spin down a HDD ? (yes this goes against all logic but this particular case)   Thanks a lot !
