I just installed Ubuntu 17.1 on my Dell Precision M6500 (so the laptop is vintage 2009-2010), alongside Windows 7. When in Windows, wifi works fine (and the LED is ON, just above keyboard). When in Ubuntu, no wifi, wifi light is off, and if I go to Ubuntu Settings, the wifi page indicates that there is no wifi adapter. If I then try the lspci command, I get this for the Broadcom devices:   dell-M6500:~$ lspci -nnk |grep -iA3 broadcom 09:00.0 Ethernet controller [0200]: Broadcom Limited NetXtreme BCM5761e Gigabit Ethernet PCIe [14e4:1680] (rev 10)     Subsystem: Dell NetXtreme BCM5761e Gigabit Ethernet PCIe [1028:02ef]     Kernel driver in use: tg3     Kernel modules: tg3 0c:00.0 Network controller [0280]: Broadcom Limited BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01)     Subsystem: Dell Wireless 1510 Wireless-N WLAN Mini-Card [1028:000d]     Kernel driver in use: b43-pci-bridge     Kernel modules: ssb   If I then follow the instructions at , I get this:   dell-M6500:~$ ls bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu3_amd64.deb  Music Desktop                                                    Pictures dkms_2.3-3ubuntu3_all.deb                                  Public Documents                                                  Templates Downloads                                                  Videos examples.desktop dell-M6500:~$ sudo dpkg -i *.deb [sudo] password for ...:  Selecting previously unselected package bcmwl-kernel-source.

The Additional Drivers settings interface is no longer available in Ubuntu 17.10  How can I install proprietary drivers in Ubuntu 17.10?  I need drivers for Wifi &amp; Bluetooth (BCM43142) and Intel Graphics.  The earlier Additional Drivers program showed a package named jockey but it no longer seem to exist in repositories.
Is it possible to install Office 365 (2013) on Ubuntu 15.04 Vivid Vervet? I would like to install Office 2015/365 on Ubuntu 15.04. I tried to install Office using Wine, but that did not work. Please note that I do not want virtualisation unless it has a -like behaviour, where application windows are treated like regular Ubuntu application windows by the system. Is there anyway I can connect resistors to allow them to take more power such as using 4 1/4 watt resistors to get a 1 watt resistors. Or do i just have to use 1 1 Watt resistor. Would someone give a thorough explanation of 1.14 Minecraft's /data modify? Okay, so I've been searching all over the internet for an explanation of data modify ever since I heard Sethbling passively mention it in one of his videos. The only  thing I could find on it was the wiki and the update log for the 1.14 snapshot. So, I checked these, and they hardly explained it at all. I can get /data modify block 123 20 123... and that's as far as I get.  Minecraft wiki does not at all define clearly what  is (the thing meant to go after coords), nor does it specify what each operation does to what. Operations include (without explanation, and excluding set (which it does explain)): append, insert, merge, and prepend. Then, it has from|value as the next option, which aren't explained either. After this, it just has block/entity and coords/id. So, I know the format (mostly), but I haven't the slightest idea what any of it means. And nothing I've seen on the internet even mentions the command save for Minecraft wiki itself.  Please explain if you know what data modify is.

I notice that my departure and return gate in the Philadelphia airport is not in the international terminal.  Where will I clear customs? Grub does not show a Windows 8 option after dual boot So, I've successfully dual-booted my Windows 8 machine with Ubuntu 12.04 . However, I still don't have a convenient method of choosing what OS to load at boot time.  After installing Ubuntu, my computer still loads Windows 8 directly. I then added grubx64.efi to the white list of my boot loader. But after that, my machine loads Ubuntu directly without even a shadow of GRUB showing up!  I used boot-repair and I got this paste.ubuntu URL: . After running boot-repair (and re-white listing the grubx64.efi file), GRUB now shows up but without any Windows 8 option!  Lastly, I ran sudo fdisk -l and it gave me this:  WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

I'm guessing my problem has something to do with the warning from fdisk above but I don't know what to do with it. How do I proceed now?

The tutorial (which uses, 11.10, I must note), doesn't mention anything about this problem. Is there anything there I shouldn't have done? A man wonders why perforations don't work.

I am using the crop package to add bleed and crop marks to a document. This works fine for pages with white background, but how do I achieve this for pages which have another colour in the bakckground?  I tried the pagecolor package, and see that it somehow extends the pagecolour to around 2 to 3 mm into the bleed but not beyond. How do I make the entire bleed region of the same colour as the page?  \documentclass[12pt]{article} \usepackage[dvips=false,pdftex=false,vtex=false,paperwidth=138mm,paperheight=216mm]{geometry} \usepackage[noaxes,noinfo,cam,dvips,pdftex,center,width=168mm,height=246mm]{crop} \usepackage{xcolor} \usepackage[english]{babel} \usepackage{blindtext} \begin{document} \pagecolor{orange} \blinddocument \end{document} Is there a way to see the history of questions protected by me or another user? Having a record of all actions taken on a site, as is provided by the &quot;activity&quot; and &quot;votes&quot; tabs of our profile, comes in handy very often. Perhaps the most common case is being able to find a question I've interacted with in the past, to see if anything has changed about it. This applies to questions a user has protected as much as anything else. Users are theoretically encouraged to unprotect questions when it's no longer necessary, as emphasized , but in practice they often do not. In many cases it's hard to blame them: unless they specifically marked it as a favourite, the site doesn't keep any record of the question to allow them to find it again. We should help users more easily review their own protections in the future.    For personal review, the votes tab is adequate, but there may also be value in displaying this publicly in the activity tab. There may be users with a history of repeatedly protecting questions over-eagerly. It would be useful to be able to review other users' protection histories to see if this is the case. Even if this is not available to regular users, it may be helpful to moderators, unless their user activity views already allow them to filter down to see this. The identification of an electron as a particle and the positron as an antiparticle is a matter of convention. We see lots of electrons around us so they become the normal particle and the rare and unusual positrons become the .  My question is, when you have made the choice of the electron and positron as particle and anti-particle does this automatically identify every other particle (every other fermion?) as normal or anti?  For example the proton is a particle, or rather the quarks inside are. By considering the interactions of an electron with a quark inside a proton can we find something, e.g. a conserved quantity, that naturally identifies that quark as a particle rather than an antiparticle? Or do we also just have to extend our convention so say that a proton is a particle rather than an antiparticle? To complete the family I guess the same question would apply to the neutrinos. What is the metal sheath surrounding a USB connector, and is it commonly connected? Isomorphism between dual space and bilinear forms Studying from Roman's Advanced Linear Algebra, I want to prove that $$U^* \otimes V^* \cong (U \otimes V)^* \cong \hom(U,V;\mathbb{F})$$ The author proves that $U^* \otimes V^* \cong (U \otimes V)^*$ by showing that there is an unique linear transformation   $$\theta:U^* \otimes V^* \to (U \otimes V)^*$$  defined by $\theta(f \otimes g)=f \odot g$ where $(f \odot g)(u \otimes v)=f(u)g(v)$  I want to prove that $U^* \otimes V^* \cong \hom(U,V;\mathbb{F})$. I tried to use the universal property by fixing $f \in U^*, g\in V^*$ and defining $S: U^*\times V^* \to \hom(U,V;\mathbb{F})$ as $S(f,g)=F_{f,g}$, where $F_{f,g}(u,v)=f(u)g(v)$, but I got stuck. Find $x,y$ given $\gcd(x,y)$ and ${\rm lcm}(x,y)$ What is the typical post processing work flow for amateur photographers? I love photography; I hate postprocessing.  Seeing that I am an amateur, not just by virtue of not getting paid for it, but also being rather new to the whole affair, I already am used to most of my shots just not being that great. While reading blogs and websites I get the impression that condensing ~100 frames in maybe a handful of shareworthy photos is not rare.  But even so, after a vacation quite a few photos have accrued. What is a common workflow to sort, post-process and share photographs for a beginner? What are common postprocessing steps? What kind of automations do people use?    Edit: I phrased the question generically so that it can be of use to as many people as possible. But I understand that without anything to go by, it might be a bit hard to answer. Therefore, while I own no paid-for software, this is what I use:   I have an EOS 500D crop camera as picture source and I use  for development,  for any touching up I need to do. (Which is not much, so far.)  (in a VM) is my photo catalog. My destination is my Flickr stream for the most part, sometimes I send photos directly to family and friends.   On the input side, I mostly am in practice mode; shooting whatever I can place in front of my lens. I have not yet picked a specialty. I would like to minimize time spent fine-tuning photos in software. These sort of "batch processes" are a part I realize is important, but not much fun to me.  I am quite computer-literate, so I am not afraid of piecing together tools that can be of use, but the more "" this can be, the more people who don't spend their life in front of a PC can benefit too. :) If spending money on something will make my life easier, I am quite willing to consider it. However as photography does not bring any income, something as large as Photoshop (for example) is somewhat hard to justify as an investment. Order of a group and subsequent subgroups I want to prove that if the order of a group G is greater than 1 and non-prime, then G has a subgroup other than the trivial subgroups {e} and G itself.   I am confused because I am only being able to prove the case for prime order by using Lagrange’s theorem i.e. if I have a group of order p, where p is a prime number, then the order of subgroups must divide p, hence the order can be either 1 or p.   How do I go about proving the case for non prime order let’s say x > 1? Is binary logistic regression a special case of multinomial logistic regression when the outcome has 2 levels? What is the correct way to edit a crontab file? Two spacecraft pilots travel at light speed, meet back on Earth in different era due to time dilation I've been looking for the name of a sci-fi romance book about space travel but haven't been successful so far. I came across it a few years ago, read the plot on its back cover but didn't read the book. It is about two spacecraft pilots, a man and a woman, who travelled at light speed (or maybe FTL, I can't remember) in separate ships. Every time they return to Earth, centuries have passed on Earth because of time dilation. They meet each other for a few times on Earth in different eras, but don't know when, if ever, they will meet again. I don't know how it ends.   If anyone knows which book I'm talking about, could you please tell me the name? Thanks a lot! Interactive / Real time code compilation for stackoverflow.com.
