Catching up

The year - 2015

It has been some time since I wrote one of my Computer Corner articles and I feel it is time to start catching up. Let me say that both 2015 and 2016 were not some of the best of times, nor great times for doing projects. I did do one update in November of 2015, but mostly I spent my time on my back. Let me explain.

For many years now, I have walked my two dogs in our regional park three days a week. The walk of 3.3 miles is up and down some hills and has kept me healthy for sure. Except for early 2015 when I started having right leg only pains. The pain got so bad I could not do much more than lay on the floor all day. After many doctor visits and tests, turns out I had ruptured a disk and needed surgery to relieve the pressure on a nerve. That all happened one week before my son's zombie wedding and my wife took her annual trip overseas. Although I literally walked out of the hospital after the operation the same day, I spent several months taking it easy and not doing much, including projects.

It took some time but I did do an update to CCII 39, warning Win10 users about default settings that send all your keystrokes to MS. I had started fixing a S100 system, but even that is still sitting in the same spot it landed at during the start of 2015. In fact I suspect it is responsible for my back problems. It easily weighs in at 75 pounds and needs a new home. I will be listing all my S100 stuff for sale soon.

The year - 2016

Some of my back problem was caused by making many trips to my Mothers place in Napa, about an hour and a half trip one way. My mother at the time was 98 years of age and for some of 2015 was still taking complete care of herself. Starting in late 2015 and into 2016, she started having minor issues that eventually became major problems. By early 2016 she was having issues regularly and I spent many a night or week at her place. This all ended in March after 30 days in a nursing home.

That then started the clean her house out and get it ready for selling. My older brother is the trustee and basically was doing a good job of running everything. But, it did mean many trips in my monster van bringing things home for later disposal. I now have many more tools and house items than I need. To say that all took up lots of time is putting it simply.

To end out 2016, I can say the house is sold, most of the "junk" from my mom's place is gone to new homes, and that is all looking good. On the bad side of things, we had the election, not good, and my brother's wife died after fighting cancer for 12 years. Needless to say, I am looking forward to 2017 being better that the last two years have been.

What next

I am starting to do some catching up on projects, with the beer temperature article to be finished next. I have started cleaning things out, a carry over project of cleaning out my mom's place. My wife will be retiring this summer and we are thinking about more and longer trips overseas - maybe even moving for good. We started thinking about moving about ten years ago but just have too much "stuff". We did get rid of some of the "stuff" but now have more. So check back here soon to see my list of items for sale, including books and S100 stuff.

I primarily use Linux, but from time to time turn on the Windows 10 system to get updates and see if anything works better. I still can not recommend it, way too many things you can not change or stop happening. I have had it update and reset the whole computer while in the middle of a Skype session. I reset one setting only to have it say it would reset the change during the next update. I have talked about the default setting of Win10 sending all your keystroke to MS, and my guess to the NSA as well. So for me I keep on using Linux, it only gets better with time.

The Debian live or build your own tools has had some changes but will still allow you to "roll" you own Linux. I have updated my last set of CDROM disks and will be adding them to this page. The overall size has increased and so the tools in my CDROM versions have dropped some, but the idea of custom or specific releases still works. I have even made a version with the next release of Debian on it - that will be version 9 and called "stretch".

I was using a RaspberryPI 2 for almost everything, as you can buy them at Fry's, off the shelf. Pretty neat just walking in and out with a new RaspberryPI system. Although I checked over the Xmas holidays and they were well out of stock. A while back I checked out my old beagle bone systems, one had died or was killed by the Harbor Freight solar charger - not sure which happened, but it doesn't work after a year on line. I look at what is going on with RaspberryPI and compare it to most of the alternatives, including the beagle bone and the RaspberryPI has the market cornered and then some. I like beagle bone design and I/O but they haven't upgraded it or provided alternatives at all. While the RaspberryPI people keep putting out new designs every few months. Talk about people knowing how to make and market a product properly, it is certainly the RaspberryPI folks.

It wouldn't be proper without a word about 64 bit systems and lack of i386 releases of Linux. First off, support for i386 is still on going, and several versions are being created specifically for older systems. It is important to understand that i386 is just short for 32 bit systems. The CPU types supported are now the 586 and 686, with I think the actually 386/486 chips being dropped from the kernel updating. Having said that, those systems are getting rather old and starting to just die. I recently did some old system cleaning and updating for selling at the next ham swap meet. All got updated to Debian 8 with no problem, however they took forever to do the updating. When comparing an old i386 system next to a 64 bit system one can see that most of the newer products just do things faster. Where the real difference comes in is in number of cores or CPU's to throw at any task. Having more CPU's always works better.

Will I be completely getting ride of all my i386 systems - NO. Most of these older systems have real serial and parallel ports. Doing embedded projects, often requires a good working serial port which newer systems don't have. You can buy serial cards and I have, but having one or two older systems makes some projects so much easier to do. For example, I have an old laptop with Linux, that is currently connected to the serial port of my S100 system. I remember too, that some of the real old laptops had a terminal mode, where you could turn them into a terminal with a series of keystrokes - sweet.

Some time back I was trying to read some of my 8 inch disks using tools I had set up for that. It seemed what I really needed was an old PC that still had ISA bus and not the newer PCI setup. I looked and none of my old systems had the bus. I corrected that at the next swap meet and it is another project to be worked on later this year and a good reason to keep some of the old systems. Don't forget that these old systems make great routers or firewalls. I got one I plan on setting up to switch between two networks when the network bogs down with traffic or goes off line due to weather.

Linux 102

Some time back I did an update to my Linux for new people and did ccii_38. I covered some new concerns for user, like keeping hacker out of your system. Recently I was catching up with a system I had setup for a relative and tried to log in remotely. Something had changed in the couple years since I logged in and was unable to do my magic.

Since what I do whether remote or in person is pretty much the same, I put together a list of steps for him to try till I can get there in person. The idea is to first understand what system I am working on and what state it is in. My relative couldn't find the Chrome browser and so I also list how to search for special or funny named packages. Overall the steps are simple and might help anyone understand Linux better. These are all command line steps, so enter a terminal to do them.

1) Bring me up to speed on what is there, hardware then software.

2) At this point I would feel that I know and have most of the basic things covered.
Since you might have a software problem, need to check for proper update/upgrading.

Is my sources list correct for updating?
> cat /etc/apt/sources.list

NOTE: if we want to upgrade to jessie, we edit the above file and change all the wheezy
to jessie, save, then run "sudo apt-get update" followed by "sudo apt-get dist-upgrade"
and  answer yes to the 1500 to 2000 packages to be upgraded. This should take over an
hour to download and upto/over five hours to install everything. You will need to watch (somewhat)
the installing step, as there are several prompts that must be answered to keep it going.
Hitting return for all of the prompts is the default and works just fine....

3) At this point I would feel pretty good that all the software is current and installed.
If the kernel got updated, I would probably reboot to be sure the system is using the latest.
Most other software doesn't need a reboot, as next time it is used it will get the latest version.
Since there was a concern about using Chrome or video drivers, I might check them out.

Description-en: Google's open source chromium web browser
 Chromium is an open-source browser project that aims to build a safer, faster,
 and more stable way for all Internet users to experience the web.
 Chromium serves as a base for Google Chrome, which is Chromium rebranded (name
 and logo) with very few additions such as usage tracking and an auto-updater
 This package contains the Chromium browser.

Typically at this point you would do "sudo apt-get install chromium".
In looking at the "show" listing it looks like it becomes the default gnome browser.
So while using gnome, the browser might just be chrome....

4) Time to check out video system. My lspci returned
01:00.0 VGA compatible controller: VIA Technologies, Inc. KM400/KN400/P4M800 [S3 UniChrome] (rev 01)
or needing the chrome driver, so:
> dpkg -l | grep -i chrome
ii  xserver-xorg-video-openchrome        1:0.2.906-2+deb7u1                 i386         X.Org X server -- VIA display driver

Let's see what is in that package
> dpkg -L  xserver-xorg-video-openchrome

So we have the proper driver, did the display driver get loaded?

and it goes on for many more lines. Basically it loads and runs, but log shows some minor
issues, such as some mode might not be supported in this chipset. Some browsers use the
chipset for scrolling and as such, if not supported, might not have smooth scrolling.
So - doing a good read of the Xorg.0.log file might give some clues about what is going
on, if it is a chipset issue.

5) It might help if I show what a new 64 bit CPU info list looks like. Note the "flags"
list, which are supported modes internal to the cpu - or features that make things work better.
Also consider bogomips, cache size, and number of cores.

My web server - the first of two cpu's (total system power usage = 12W):

And so we have a list of commands you might want to try to see what is going on with your system. The user was having slow browser scrolling and minor problems related to using the internet and a few programs. I suggested time to upgrade to a 64 bit system, as some issues might be just the slow speed of the cpu or features that the new CPU's have and might be called by more current programs to get better speed.

Till Later

That should bring you up to date with what has been eating up my time for the last two years. I expect to have more free time, but clearly expect things to pop up and fill all that so called free time before I have a chance to think about it. I hope your next year goes better than my last two. By the way - Happy New Year!
