And sometimes (but not always), after I run Diagnostics, a "Network Change Detected" window pops up.

I stupidly moved timemachine back-up folders to the trash thinking I could delete them that way, but no, you cannot. I cannot put them back into the back-ups folder and delete them via time machine. I have tried taking one out of trash to my desktop and deleting via terminal using

sudo tmutil delete

which I found on a help forum somewhere, but I get the message "Unrecognized verb"

A friend of mine just bought a Dell Inspiron 15 5577. It has an SSD, and a 1TB Hard drive. The old laptop had just been upgraded to a 2TB HDD, and we'd like to pull the data from the 2TB HDD, then clone the new one to the 1TB, and put the 2TB HDD in its place.

I may be coming in too late. I don't understand quite what is going on. Is the goal that the new laptop will have the SSD and 2TB HDD while the old laptop will have the 1TB HDD?

My computer is not upgraded and all stable again. I'm sort of forced into running Ubuntu 17.10 even though it's in alpha still, but 17.04 doesn't have a new enough kernel for some of the new hardware. I could still use 17.04 and just install a newer kernel, but I'm not sure that's any better than just jumping on 17.10 early.

Anyhow, I was able to to take 25 million lines of JSON data in 100 files, transform it all, combine it with static data from a massive csv file I read in and hashed for quick lookup, and write out the enriched and re-grouped data in csv files all in 40 seconds. I used 8 threads in the program to balance out over the 8 physical cores in the processor. AMD has made a badass processor with this new Ryzen stuff.

Um, that makes no sense to me, but since I know that Gud is badass, I am sure that he did something awesome.

Yes and no, the old laptop has a dead motherboard. However, since the new laptop is indeed using the SSD for Windows and Apps, the HDD is virtually all for data, and have advised her to just transfer what data she needs to the new laptop for now, and run with it

I had my hands on it today and it's a wonderful little laptop which boots quickly off the SSD.

She uses her computer for Photography-intensive tasks, including Photoshop and After Effects, so I I advised her to get a gaming-level PC for the video-processing power. The new one has a 2GHz i7-7700HQ processor and 12GB RAM, with a 4GB NVIDIA GTX 1050 Graphic Card and a 2-year concierge warranty from Costco.

I hooked up my secondary hard drive last night and my computer promptly stopped booting up. Which was weird. If I disconnected the secondary hard drive, everything was fine again. A firmware update to the motherboard fixed the problem fortunately.

I tried that same data processing job on my work computer (MacBook Pro w/ 4 core 2.5Mhz i7-4870HQ, 16GB of RAM, SSD) and it took 75 seconds.

It may be time to replace my early 2011 macbook pro. Any thoughts on the new macbooks? Feelings on the touch bar? The most demanding program I use is VectorWorks. I'm likely to be choosing from the apple refurbished page.

Aurelia I just got a pro with the touch bar. I have yet to use it for anything other than changing the volume. But I wanted something with more than one port. I also went with refurbished. ...otherwise I got nothing. My old computer was a 2010 MacBook Pro, so anything would seem sleek and awesome next to that!
