I have windows 8.1 installed on my PC. I have 3 wired broadband connections, but I cannot connect to two or more connections at a time. For example I want to use all three connections jointly to download torrent files and other files using Internet Download Manager. How do I achieve this in Windows 8.1? When I manually connect, I get the error saying "You can only connect to one connection at a time".  Is there a cost-effective solution (I prefer software tweak) to use all three broadband connections for these programs in windows 8.1 or can I do something different if I switch my OS to Linux (probably Ubuntu). Please explain the steps if there is a way to achieve this. Thanks in advance
We have a broadband line coming into our building which delivers around 8-10Mbps, which is okay but not great. Fiber is available in our area (30-100Mbps) but it's not available where we are just yet.   Is there some way we could connect two lines (which we would take from two different providers so we would have redundancy if one failed) and merge them into one signal which we could distribute?  Is there some sort of setup that can do this?  Of course we have the option of a leased line but for 12Mbps symmetrical upload/download we'd be looking at around £500 per month compared to £15 per month for normal or fiber broadband.  I made a small pseudo flow chat of the setup below:
Can someone provide a proof that every quadratic residue, when working in $\mathbb Z_p$, where $p$ is a prime, has exactly two roots? Indeed, there cannot be only one root as for any $a^2$, we know $a$ and $-a$ are both roots. So then we need only show that there cannot be more than two- does this follow from some argument for the number of roots a quadratic can have modulo a prime? I'm not well-acquainted with the theorems pertaining to prime moduli. I'm new to d20. I recently acquired a bunch of D&amp;D books and I'm sure they are all either 3.0 or 3.5, but it doesn't say in the book which version it is. How can I tell which version the book is?  For instance, I have "Complete Warrior - A Player's Guide to Combat for All Classes". It's hard back, published in '03. Is it 3.0 or 3.5?  Another example, I have "Sword and Fist - A Guidebook to Fighters and Monks". Perfect Bound, published in '01. Is it 3.0 or 3.5? adb device doesn't listed on cmd {Lenovo K8 Plus} I am trying to root my Lenovo K8 Plus after unlocking bootloader. I try to install TWRP and somehow the TWRP recovery doesn't open and the phone is struck in the bootloop. I then fastboot the device and connect to PC and open minimal fastboot cmd. The phone wasn't listed in adb device, but listed in fastboot devices. I think usb debugging is not turned on because the system doesn't restart (maybe there is no ROM). What should I do? Programmatically delete one entry from one field on one entity What's the proper way to programmatically delete one specific field entry for a multi-entry field from one specific entity? (that's specific fields and specific entities, not field types or instances and entity types)  Here's some possibilities I've looked into which don't work:   Loading the entity with entity_load(), setting the field entry to =null or =array(), then saving with field_attach_update(). It's the closest I've found but it leaves a zombie null field entry in the database which shows up as a blank row on forms until the form is saved and hook_field_is_empty() can kick in (hook_field_is_empty() is configured such that =null or =array() will flag as empty). Loading the entity with entity_load(), unsetting the field entry by key, then saving with field_attach_update(). This seems to do nothing - it seems that Drupal interprets the entry not being there as a sign to not modify it. (strangely I also sometimes get maximum query time expiration timeouts when trying this approach) field_attach_delete() - this is much too blunt: it kills all fields for the entity field_purge_data() - better, but still too blunt: it kills all entries of the field, not specific entries   So to clarify, I've got code that finds (and loads) an entity which has a field that has multiple entries, and finds a specific entry on that field that needs to be removed. I want to remove that entry completely, without touching any other entries or any other fields on the entity. Calculate the components of a unit vector that lies in the xy-plane and makes equal angles with the positive directions of the x- and y-axes It's just a doubt.  $\vec { A } = A \hat{ x }  + A\hat { y} $  $ A\hat { y} =A\hat{ x} $  $\vec { A } = A \hat { x }  + A\hat { x} $  Now finding the magnitud of the vector,  $A=\frac { 1 }{ \sqrt { 2 }  } $  So the components of the unit vector are:  $\vec { A } = \frac { 1 }{ \sqrt { 2 }  } \hat { x } +\frac { 1 }{ \sqrt { 2 } } \hat { y} $  Is my answer right? Change the default size of square brackets in latex math mode Personally I think the default size of square brackets in latex math mode is too small. For example, for an interval [a,b], I would prefer \big[\big] as opposed to plain []. My question is, what can I do to change the default size of [], so that when I input [] in math mode, they will show up automatically the same size as \big[\big]?  Right now I'm defining a new command called \b{} which takes one argument and inserts it between \big[ and \big], but the code looks ugly. Apparently \newcommand (or \def or \let) does not allow [ to be refined.  Any help is much appreciated. Thanks.

Reduce Classification Probability Threshold I have a question regarding classification in general. Let $f$ be a classifier, which outputs a set of probabilities given some data D. Normally, one would say: well, if $P(c|D) &gt; 0.5$, we will assign a class 1, otherwise 0 (let this be a binary classification).   My question is, what if I find out, that if I classify the class as 1 also when the probabilities are larger than, for instance 0.2, and the classifier performs better. Is it legitimate to then use this new threshold when doing classification?  I would interpret the necessity for lower classification bound in the context of the data emitting a smaller signal; yet still significant for the classification problem.  I realize this is one way to do it. However, if this is not correct thinking of reducing the threshold, what would be some data transformations, which emphasize individual features in a similar manner, so that the threshold can remain at 0.5? As the title says. I use, among other things, the following in my lstset:  framerule=1pt, frame=tblr   Some places a page break happens in the middle of my \lstlisting. Fine. But sometimes the whole code of the listing appears on one page, but the bottom frame appears on the top of the next page!    I know that I can float a particular listing, but I have a long document with many listings, and I don't want to float all of them; Most of them also need to be exactly where they are declared. That they are broken over a page doesn't bother me that much.  Is there something that can stop this from happening, without me needing to adjust each individual listing?   had the same problem, but fixed it by removing spaces in front of keywords in a custom language definition. I too have a custom language definition, but his solution doesn't help me. I managed to recreate the situation without a custom language.  Edit and MWE  I managed to reproduce it in a minimal working example. 's a pastebin, if that's helpfull.  \documentclass[UKenglish,a4paper,11pt]{report} \usepackage{babel}  %% Adjustments \addtolength{\topmargin}{-1\baselineskip} \addtolength{\textheight}{4\baselineskip} \pretolerance = 2000 \tolerance = 5000   \hbadness = \tolerance  %% Smaller font \usepackage{mathptmx}  %% LISTINGS \usepackage[final]{listings} \lstset{     xleftmargin=1.5em,     framexleftmargin=1em,     framextopmargin=0.5ex, %%  THE FRAME:     framerule=1pt,     frame=tblr }  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%  \usepackage{lipsum}     % for demo \begin{document} \subsubsection{Lorem}   % some fiddling to get the "wrong spacing just right": \lipsum[1-3] \subsubsection{Ipsum}  \lipsum[1] and then some text  \begin{lstlisting} Here is a listing with three lines of code; The bottom border is placed on the next page! \end{lstlisting}  Can you believe it..?! \end{document}   This MWE is rather long. My document inputs most of the listings stuff from files written by others, so I'm not sure what all of it does. If anyone sees some lines that they are sure is irrelevant, feel free to take it out of the MWE.  "Fun fact"  An equally silly situation occurs if you remove \usepackage{mathptmx}: The whole code listing will then appear on the new page, except for the top frame which is left on the bottom of the first page! I was caught cheating on an exam, how can I minimize the damage? I got caught cheating in a two-hour engineering exam consisting of 100 multiple choice questions which was done online through the  e-learning software. I feel like my life is almost over.  Having not studied well and having no time to study, I decided to cheat. I know there are no excuses for cheating. Before the exam I dug up research about moodle exams, and it turned out you can take the exam anywhere you want to as long as you have the quiz password. Taking advantage of this, I went up to my engineering library and asked a close friend who was taking the exam to send me the quiz password before he starts.  What I had prepared:   Calculator (was not allowed during the quiz). Printed material (consisted of more than 200 pages). Google search engine (on a laptop ready to help). Whatsapp (to ask questions for a friend who took the quiz last year).   As I sat down, I did the first 50 questions, suddenly the quiz froze and moodle told me:      you are not allowed to take the exam from this location.   While I was leaving, one instructor responsible for the course (there are 5) came and found me. She accused me of cheating, took my mobile and made come with her to a huge office where two instructors searched all my mobile (took the name of my friend who gave me the password), and started talking to me, asking for all details of this crime. They took and confiscated my phone and looked at everything: Whatsapp conversations, all my emails, and images. The instructor took the mobile from my hand without asking me and kept it with her. It seems that the instructors are going to report me as well as my friend who sent me the password for the exam.  The university's Student Code Conduct said that cheating will result in one of the following: a Dean's Warning, Suspension, or Expulsion. If any of that happens, my future is over. A dean's warning will cancel my financial aid. A suspension would be for at least two years, and coming back would require a lot of work. An expulsion will be definite.  I've learned the lesson about cheating, now how can I fix this? How can I prevent the five instructors from reporting me? It's obvious that I should speak to them, but what should I say? What can I do? My future is almost over, but many of you are teachers and instructors here, what can I do to fix this?    EDIT: Wow, it has been almost 3 years. I would like to update on how I dealt with the situation.   Lesson: It was obvious to never ever cheat under any circumstances, and it was not whether you'd get caught or not.    Consequences: I received a Dean's warning but the financial aid wasn't revoked. However, I couldn't stay in the department as engineering was not for me and I was even ashamed to stay in the university.  What happened next: I transferred to an ABET-accredited Computer Science institution and I graduated with distinction in 2.5 years. It was extremely stressful as I had taken 6 major courses (18 credits) in one semester, but I had to do it.  Future plans: I'm going for an MSc in Computer Science in St Andrews next year. Does the shebang determine the shell which runs the script? This may be a silly question, but I ask it still. If I have declared a shebang  #!/bin/bash    in the beginning of my_shell_script.sh, so do I always have to invoke this script using bash  [my@comp]$bash my_shell_script.sh   or can I use e.g.  [my@comp]$sh my_shell_script.sh   and my script determines the running shell using the shebang? Is it the same happening with ksh shell? I'm using AIX. What is the difference between old style and new style classes in Python?  When should I use one or the other?
