comment How to set up two internet conenctions, on LAN with NAS
In terms of combining, both networks provide access to the internet, so in terms of routes they both provide the same WAN routes. If you want them on one network then you need to configure them as seperate gateways in your routing tables. You can keep them as seperate wireless networks by splitting them up in subnets - configuring routes to route between the two local networks but using the LTE or ADSL gateway depending on which wifi you connect to

comment Computer stuck on bootloop
Silicon Dies randomly sometimes, I'm assuming you are overclocking with the water cooling? Did you mess with voltages for CPU or Memory? Resetting BIOS/Firmware may help if a brownout or supply issue caused the eeprom to get corrupt, but to me the symptoms sound like something died. Most modern motherboards can detect firmware corruption and boot into a well defined state, what you are experiencing sounds like a hard HALT on boot, which is typically a damaged component

comment Testing 10G Ethernet with two NICs?
Two boards in one pc will bring have seperate mac and ip stacks. The phys on the chip will bring up a 10g link if it can. This doesn't mean that you can send and receive 10gbit stream as you have bus and cpu bandwidth limitations, but you can query the MAC for the link type and status to confirm 10gbit link

comment Overclocking an AMD card
The silicon is rated to roughly 80C at most for continuous operation. You are likely to experience side effects before you hit the temperature maximums.

comment What cable do I need to perform this connection
"VGA with audio" is a standard VGA cable with a 3.5mm audio cable stuck to it.

comment Do desktop computer motherboards have GPIO? If they do, how to read from or write to them
@Mohsen its not really an answer as much as a general state of consumer hardware, I'm sure there are x86 devices intended for embedded applications that have on board gpio. BTW datasheets for Intel and AMD cpu's are generally available on their respective websites, you can see what peripherals are available on die. The general conclusion is that high end consumer devices like the i7 have a handful of high speed buses and standard interfaces for memory.

comment Do desktop computer motherboards have GPIO? If they do, how to read from or write to them
x86 CPU's will in general not have GPIO pins, with every pin being directed to a specific on-die peripheral without PIO multiplexing that is common on MCU's. HOWEVER, GPIO like functionality is often part of the architecture and handled by (typically memory mapped) peripheral on the motherboard, the chipset will often have some low-level buses (SPI and I2C for sensors) as well as GPIO's available, the exact nature depends on the motherboard and chipset/architecture used.

comment VGA to S-video/video converter won't work
Is it a cable or an actual converter box? S-video signaling (Chrom/Lum) is incompatible with VGA (RGB), however many videocards are capable of outputting SVideo as video out and some may multiplex a s-video output into the vga signal lines and provide a cable with the product, there is no standard for this and it is manufacturer specific .

Integrated graphics has a analog coding chip actually generating the physical signal too.

comment Intel Integrated Audio Signal Path
The Audio DSP is integrated, AC'97 is the last link to talk to a chip dealing with the analog circuitry, its basically an inteligent DAC on something better than I2C. It is also possible that the chipset integrates the DC97 and codec.

comment Intel Integrated Audio Signal Path
There is a dedicated audio bus on the motherboard and the controller lives on the chipset/southbridge , it is used both for audio output and modem interfaces. Audio chip is on this bus and the data is transfered in the AC'97 protocol, how the chip drives the analog circuitry depends on the device used.

some audio codec or DSP chip that drives a small output stage, probably integrated DAC.

comment how to SSH into a computer that's in a different WLAN?
No problem, you answer is more concise than what I started writing. The hard part is making sure that Router2 is not creating a VLAN but just acting as a switch, this may be a configuration option, but it will probably require that OP plugs the ISP router into the "LAN" switch of router2 and not the "WAN" port

comment how to SSH into a computer that's in a different WLAN?
Not true at all, you only need to change your router to either forward ports or share the same subnet. The "WAN" side of the personal router is on the same subnet as OP's PC1

comment What is an open source backup app alternative to deja-dup/duplicity that gives me more flexibility on *nix?
Practically every Linux has rsync (backup) and cron (scheduling utilit) out of the box. Between those two you can get differential backups of files with any schedule. If you want more managed backups then you can use cron to call any utility you like. Rsync stores logs and diff files and there are many utilities that can display those for you in a nice gui

comment Troubleshooting advice for Yosemite macair2014 not booting past 50% loading bar?
Whoever wrote that guide for "security" needs to be banned posting advice online, what is wrong with just using kextutil to unload the drivers to avoid opportunistic snooping? If an attacker has root access to load the drivers back in then your systems are compromised anyway and they can easily copy those drivers back so your "security fix" is useless.

comment Can I access internet by connecting ethernet to a wifi repeater
Keep in mind if this router is currently configured as a repeater (range extender) it may not function as such if you configure it as a wifi-ethernet bridge.

comment Can I access internet by connecting ethernet to a wifi repeater
Most likely yes, the hardware should support it just fine. Practically every wifi controller that can be set to AP can easily be used in infrastructure mode, and setting the device up to forwarding is straightforward even in embedded OS's. The question is how much configuration control the manufacturer gives you to make it happen. I wouldn't know that without having one in front of me.

comment Troubleshooting advice for Yosemite macair2014 not booting past 50% loading bar?
You removed system kexts, which are modules loaded into the kernel at boot time, you completely borked the system with your medling, Get an external dvd drive and reinstall from a dvd or image downloaded on another pc and call it a day. In the future it is much much safer and easier to rename/move system files than delete them if you find yourself in this position again. 9GB may not be enough space to download an unpack the image FYI
