Perhaps travelling back in time will become part of our reality, if has not already happened.
“It’s one of those things that we take for granted—time moves forward and never backward. But did you ever stop to wonder why it moves in one direction, as opposed to the other? The question continues to stump physicists. After all, there are certain physical processes that are actually time-reversible—they look the same no matter which way you run them.”
Computer researchers have recently found out that the main chip in most modern computers—the CPU—has a hardware bug. It’s really a design flaw in the hardware that has been there for years. This is a big deal because it affects almost every computer on networks, including workstation and servers.
This hardware bug allows malicious programs to steal data that is being processed in your computer memory. Normally, applications are not able to do that because they are isolated from each other and the operating system. This hardware bug breaks that isolation.
So, if the bad guys are able to get malicious software running on your computer, they may be able to get access to your passwords stored in a password manager or browser, your emails, instant messages, and documents.
The more severe vulnerability, Meltdown (CVE-2017-5754), appears isolated to Intel processors developed in the last 10 years. Spectre (CVE-2017-5715 and CVE-2017-5753) on the other hand, theoretically affects all processors that use speculative execution, including most modern processors manufactured by Intel, AMD, ARM and potentially more.
From a quick read of the many articles, mitigation will require OS patches and firmware updates from Intel, AMD, Arm, etc. For Microsoft, the patch is dependent on having an approved AV application running that sets a compatibility registry key that Microsoft updates will reference. Windows Defender and Microsoft Security Essentials are of course approved and can be used if nothing else is available.

Since 2010, I have been a devoted user of Worldmate for managing travel plans and itineraries. Despite limitations and few and far between updates, I used the website often and had the app installed on all mobile devices. So when I logged in yesterday and discovered that the service was being discontinued in March, I was sad. And now I had to find a replacement and get this years plans loaded. A quick search of course found other travelers in the same predicament. Some alternates listed were Google Now, TripCase, and TripIt. After a little reading and a trial, I decided on TripIt Pro from Concur.
The main issue I had with Worldmate was it’s limitation in managing activities and events while traveling. It was good for hotels, car rentals, and airfare, but not restaurant reservations, excursions, or planning an expedition. So far, TripIt is a great and in many ways better replacement for Worldmate.
