January 5, 2019 Update

The holidays left me stuffed, and so busy that work became an afterthought. My friend also had some medical issues and I ended up being a driver for most of the month. I swear, driving takes a lot out of me, physically and mentally. There are only a couple updates this month.

Remove Docker’s Cached Intermediate Images

Sometimes, you need to blow away Docker’s cache because an external resource changed. This is a hack to do it by inserting a “no op”.

SEO Keyword Research for Docker

Google says that advertisers are paying $35 per click for ads on some Docker-related pages. They aren’t the pages I’m writing; not yet anyway.

December 18, 2018 Update

This month, our “hobby” server took a big dump, and we said, “screw it, we need to install the ‘new’ server.” This “new” server is a few years old, but switching servers is such a huge pain in the ass that we avoided it.

Besides, the old server has been pretty reliable. We’ve had to replace the power supply, a hard drive, and memory, but… not bad for 10+ years. Fsck even fixed it up, but re-racking a heavy 2RU, decade+ year old server is a terrible idea.

I’ve got three new articles, and the first two are from this upgrade:

One new page is an aggregation of a series from a while back about fixing my personal computer:

  • The Crashing Computer Series – Long notes about how I diagnosed and fixed my crashing personal computer (it was RAM). Don’t do what I did.

I’ll try to share one article I’ve read that’s tech/internet in each post.

Radeon R5 230 on Ubuntu Linux 13

It works. Haven’t bought a graphics card since the mid 1990s, but did this because Gnome 3 feels a lot smoother with some extra cycles and memory. All the eyecandy effects now seem to run at around 20 fps, and the colors are nicer. Before, they were more like 10 fps and jumpy. This shows up in lspci as VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450]. Seems to be a bit of a power hog, but it doesn’t use a fan, so it’s not going to burn too much coal.

Also, programs run a little smoother because the memory isn’t being shared with a graphics controller. The main effect, though, is that the corner, where you push to get the task switcher/menu and the application shortcuts, comes up in around 1/4th of a second instead of one second. That makes a difference.

Free vs. Proprietary Drivers

You can choose to run this with the Free drivers or the Proprietary drivers. The free ones work well, but the proprietary ones will give you faster effects. I can’t quite tell, but it seems like the window manager is a little slower with the proprietary drivers.

Youtube/Flash videos interact better with the proprietary drivers.

Video games seem to run faster with the proprietary drivers, but the windowing system starts lagging after you run a video game, so the games probably use up all the memory on the card.

w32tm reports the computer did not resync because no time data was available

I got the message “the computer did not resync because no time data was available” after running “w32tm /resync /force”.

I had followed the various howtos out there*, and checked them against each other : as expected, they differed slightly, but none of them worked for me. Well, it turned out that I needed to run the update command, below.
