I have a 2018 Macbook pro with MacOS 10.13.6.  To have a more stable connection (compared to WiFi) I got a "Belkin USB-C to Ethernet Adapter".  Initially, the adapter had a self-assigned IP which I fixed by changing how the IPv4 in Network settings is configured from DHCP to DHCP with manual address. Now the status is green and the device is assigned an IP address. However, there is still no connectivity through this device.  Any help is appreciated.
Cannot connect MacBook Pro (Retina, 15-inch, Mid 2015) (10.13.3) to the internet through my Apple USB Ethernet Adapter. I am receiving this error under System Preferences/Network:   "Apple USB Ethernet Adapter has a self-assigned IP address and will not be able to connect to the Internet." IP Address: 169.254.59.248 Subnet Mask: 255.255.0.0   I can connect to the internet with the same ethernet port on my Windows 10 machine. When I replace the IP address with a the Wi-Fi IP address I use to successfully connect to the same network under "Using DHCP with manual address", the Apple USB Ethernet Adapter icon is green and displays the message "Apple USB Ethernet Adapter is currently active and has the IP address xx.xx.xx.252." However there is no actual internet connection (i.e., I cannot visit any website).  According to  to a similar problem, I can:   Find and disable whatever firewall is intercepting the DHCP return traffic. According to System Preferences/Security &amp; Privacy/Firewall, my firewall is off. Is there anywhere else I can check for additional firewalls? Would firewalls somehow impact ethernet and Wi-fi differently?  Inspect the network traffic or the router logs to see if and why the Mac DHCP broadcast packet is being ignored. How do I check network traffic on my Mac? I am comfortable using the terminal.   I have also tried steps listed as potential solutions in :   To reset the firewall, go to the /Macintosh HD/Library/Preferences/ folder and remove the file called "com.apple.alf.plist," and then restart your computer. On my computer I went to /Library/Preferences/ and ran sudo rm com.apple.alf.plist If that was already set, try the "Advanced" button, then "Renew DHCP Lease" Removing their "Ethernet" config from the Network settings and then re-adding   Does anyone have other suggestions? Thanks in advance
Is it possible to install Windows 7 alongside Ubuntu and windows 10 dualboot? I installed windows 10 on my laptop in UEFI mode with HDD GPT disk format, then I installed Ubuntu 16.04LTS on another partition. So I have Ubuntu dualboot with Windows 10 now.  I also installed rEFInd (it's like GUI for you to choose between different OSs) because I don't wanna use Grub2 as the default bootloader. Now I want to have Windows 7 too, but when I boot from the USB stick, an error screen showed up saying something like  the windows boot manager is having problems due to a recent hardware change   My system is still working fine so I don't know if the problem came from my system or if the setup I want is impossible.

Definition of injective function Let $SL_n(\mathbb{R})$ be the set of $n\times n$ matrix with determinant one. Where can I find a proof that $[SL_n(\mathbb{R}),SL_n(\mathbb{R})]=SL_n(\mathbb{R})$? I've seen this result mentioned in several places, but couldn't find a proof.  For reference, the commutator $[SL_n(\mathbb{R}),SL_n(\mathbb{R})]$ is defined as the group generated by the set of all elements of the form $a^{-1}b^{-1}ab$, with $a,b\in SL_n(\mathbb{R})$.

If I could stop ALL motion would I stop time? I've never really understood time. Time is not a force. It isn't energy or matter. Time doesn't MAKE anything do anything. Time doesn't make a clock tick (motion or batteries do). Time doesn't make the earth revolve around the sun (motion/gravity does). I don't think time exists. People say time is used as a form of measurement but aren't we just measuring movement? Even atomic clocks measure the movement of electrons that orbit an atom's nucleus as they "jump" back and forth between energy states. So my question is if I were to stop ALL motion (even movement of electrons that orbit an atom's nucleus) would I stop time? Is time just masquerading as the measurement of motion?  EDIT: This question is not a duplicate of "Does time freeze at Absolute Zero?" Because I am NOT talking about temperature. I am speaking about the motion of ALL things. I am asking if ALL things (photons, energy, matter, forces) stop moving would time stand still? I would have to say yes it would. If ALL motion were to stop for a million years and then start again no one would even know. Atomic clocks wouldn't even miss a step.

One of them is Neon Genesis Evangelion.  Neon Genesis Evangelion has it in the sky in both the opening credits and in the series itself:     I also remember it was on the ceiling at NERV, but the best screencap I could find of that was too tiny to be visible.  So, my question is, Is there any deeper meaning to the use of the Kabbalistic tree of life, or is it just used because it looks cool? I'm currently trying to configure our exchange 2010 to be used as a external smtp relay. What I'm trying to do is allow certain websites that we manage to send email using our exchange server smtp relay. I was told that I needed to created a receiver connector under Server Configuration>Hub Transport. After I created the receiver connector I added the following confi in which I added the website IP address in the "Receiver mail from remote servers ect" then unders Authentication I selected Externally Secured,TLS and under permissions I selected exchange servers.   I went to one of our websites and configure it with this configuration and I'm still getting "SMTP connect failed."  Can someone help me? or what is the  proper way to get this to work. Multiple websites are going to be using this exchanger server SMTP relay in a secure way. How to sort two lists (which reference each other) in the exact same way Mesh generation from PointCloud?
