3 Ways to Deal With a Frozen Linux System . .

Appropriate subject matter . . . especially for this Winter!  And the answer is not “just move your PC to Florida” . . .  (btw – – hopefully the next OTC meeting will happen before APRIL!).

Anyway . . . this post is not about the weather, but it focuses on a user’s PC running Ubuntu (or most other Linux distros) . . . that has frozen for a variety of reasons (mainly program, system bugs or browser badware).  These freezes can impact just one program that won’t respond to user input or the whole desktop is frozen.

In Windows, one typical response is the good old “ctrl + alt + del” key sequence.   This often does nothing on Linux (although a user can create a key-binding to call the reboot command).  That is not the preferred or best way to handle Frozen systems.

The following article from the folks at “linuxhandbook.com” does a good job of laying out the options and is worth a read.   At a future meeting, this is a key topic I’d like to cover in greater detail.

How to Back Up Your Data When Your Windows PC Won’t Boot

Now, you can recover your data from a Windows PC that refuses to boot due to some malware or just a hosed configuration . . . If you have data worth saving . . . this article is worth a read and follow up.

I will be covering these points in more detail at a future meeting – – – no need to pay some local tech shop $150 or so.    Once data is retrieved, then a standard Windows install can be initiated.

How to Get the Most Out of Your Chromebook

Now you can get the best of all major computing platforms on a 3rd generation Chromebook.   You can run:

  • ChromeOS (an enhanced flavor of the Chrome Browser),
  • LinuxOS’s (Xubuntu, Ubuntu, Solus and others – by just switching tabs in the Chrome Browser) (uses the “Crouton” environment)
  • Android Apps (will run on ANY 3rd gen Chromebook, e.g., Intel or ARM),
  • MS-Windows Apps (several methods including VM’s (requires min of 4 GiB of ram).   This works but is more challenging than just running Android Apps or Linux . . .

For those adventurous enough to give it a try . . here’s more info from Cameron Summerson at HTG:

PS:   one of the “really” nice features of ChromeOS (unlike any other OS that I’m aware of) . . . is the ability to EASILY restore a pristine factory setup INCLUDING automagically restoring your personal files (photos, media etc.)!!

App restorations are also simple via the official online repos.  (Google or Samsung Store, . . etc.).

 

 

Live Sharing of Videos and Desktops during OTC Meetings . .

A handy tool to share your desktops (from phone, tablet or PC) during a club meeting.  Link below the graphic explains basic setup.   Best to also test on your digital TV at home.

Note that the PC can be a Chromebook or running Windows, Linux, MacOS but does require the Chrome browser on the PC and “Google Home” app on the other devices.

Meerkat Bluetooth Speaker Musings

I thought that I would list the results of using Bluetooth to connect to speakers.

I have 3 Bluetooth devices: and Insignia Stereo Speaker, Echo, and Trekz Titanium bone-conducting headphones.

After pairing the Insignia works, but the speakers are just fair. The Echo has much better sound and pairs well after giving Alexa instruction to pair. The Trekz is great with the day long live and clear sound. It’s like the sound from an old stereo.

Yesterday, I hooked up the Echo to the Mercat. After playing for about a half hour the sound became scratchy. This also happens with the Insignia, often it is scratchy from the start.  But it has never (fingers crossed) happened with the Trekz.

So I am wondering, do the processors get overworked? It never happens when the Echo plays my Amazon music. I would think that the audio signal is not being decoded when the distortion could occur.

So I am asking the group for explanations of this phenomena.
