My home wifi is still acting weird with my laptop. I've realized that, when it disconnects, it takes a while to completely disconnect -- if I've got Twitter open, then sometimes new tweets will keep on loading for a few minutes (but without pictures) while other windows say that there's no connection. Sometimes I still get Facebook notifications, too. And if I wait for a page to totally not load, and then click the "Run Network Diagnostics" button, then that usually fixes it. Any ideas how to stop this from happening in the first place?

Hil, Does it only happen at home, or elsewhere, too?

Friends, Romans, and various tech geeks thereof.

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.

The only thing new to me in this situation is the SSD as a boot/OS drive. Are there any special considerations?

Assuming, of course, the 2TB is a compatible (7mm) size to fit in the new laptop.

It happened a couple times when I was at our vacation house, but I'm not sure if it was the same issue or just that the wifi there wasn't great. It hasn't happened when I've used this laptop on campus, but I don't use it on campus often, so I'm not positive that it would never happen there.

When it happens, and I pull up the "Network Diagnostics" (it's a Mac), there are green lights for Wi-Fi, Wi-Fi Settings, Network Settings, ISP, and Server, and a red light for Internet. Then when I run diagnostics, everything except Wi-Fi goes red for a couple seconds, then back to green, and then it works.

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"

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.
