Re: [PLUG] Multi host init system?

[Nathan Williams]

i haven't had to actually do this yet, but if i understand the systemd
socket-activation concept correctly, that may be a useful building block
for putting something like this together (service gets started when another
service tries to access it over the network).

thankfully we don't have any super order-dependent services like that (they
just enter a retry loop until their dependencies are available), but i'm
tempted to try it out now :)

Given your chain, each node consumes data from the following one. 
Node I generates the raw data. The system is designed on a pull 
model. If C fails B and A think there's no work to do - and eventually 
generate alarms because they expect there always should be something 
to do.  D will write to local storage. When C is brought back it will 
process the queued data on D. 

Aside from getting disk arrays, databases and message queuing services started
there are no actual hard dependencies. The desire to control and coordinate 
startups is threefold.

 - ensure health of component before going forward
 - not populate logs with messages about lack of services
 - not generate a backlog of data to be processed when the full system is up.

If instead of a pull model there was a push model then the pushing node
could start the downstream service when it had something to push. Nothing
would be started until it was needed the first time. Also if it can't start
or find anything to push to it can send a message upstream pausing the rest
of the nodesl much like the kill switch in the Toyota production line. No
matter how finely it is tuned one of the nodes will be a bottleneck and
will have to pause the upstream line occasionally even under normal
conditions.

[PLUG] What CMS to use ?

[Pete Lancashire]

It is time for me to start posting 'stuff' on one of my domains.

Looking for comments good and bad on a CMS to use.

My hosting company provides Wordpress, Drupal and Joomla

Other then must be close to 7 years ago I played around with
Drupal and Joomla. That is about the limit of my experience

The link did not work for me (it was truncated). Here is the full line -

Personally, I prefer Python to PHP, so I prefer working with the django

that are based on dhango. There are others as well.

[PLUG] Using GitHub Download

[Rich Shepard]

   An update to a 5-year-old book is being written with code available on the
project's github page. The author asks for feedback on the developing second
edition, and I need to learn how to use the subject of the book (ggplot2 for
R graphics).

   My Web search taught me that there's a 'download everything as a .zip
file' button on each project page. I used that link and now have a local 
directory
that is supposed to be the entire source, but I cannot find the *.tex files
to compile. Do I need a github account to get everything needed to build the
document locally?

   Suggestions and advice appreciated.

Re: [PLUG] Using GitHub Download

The zip file from a release should have everything from that project that
is expected to use the project.  If not then that should probably be opened
as an issue.
To open an issue you probably do need a github account.

[PLUG] Desktop machine failures

[Denis Heidtmann]

Well, it is at it again.  Second boot of the day I got the same error I got
a 6 days ago:  "Error 16: Inconsistent file system structure. Press any key

A key press gets me to the menu of OS versions.  On choosing the usual
(12.04) I get partway into the Ubuntu startup, then a black screen with a
flashing cursor.  ^ALT DEL soon produces the msg.
"Busybox v 1.18.5 (Ubuntu1:1.18.5-1ubuntu 4.1) built-in shell (ash)"
"Enter help for a list of built-in commands"
Prompt is (initramfs).  I enter exit.  Then I get the kernel panic
messages.  (They are identical to those I got the last time.

This time I used e2fsck -fvp /dev/sda1 from the Ubuntu 12.04 live CD.  No
errors found.

Then I ran the smart self-test in palimpsest (a gui).  It took two hours,
but found nothing wrong, as far as I can tell from the report.

System seems fine at the moment.

Short of a new computer, any ideas?

Thanks,

A shot in the dark, but what kind of drive are you using for your root 
filesystem? I read recently about TRIM on SSD being broken in some 
cases, so if you have traditional spinning platters this is going down 
the wrong path.

Re: [PLUG] Using GitHub Download

[Nat Taylor]

Read the README.md file that comes with the project.  If you scroll down
its going to be printed out on the screen, too, at the bottom of the list
of files.

If this is the one: https://github.com/hadley/ggplot2-book
then you read the README.md which I have pasted below.  Ideally you have
RStudio installed, note the highlighted part.  Otherwise you type the
commands on the command line.

You're going to need git installed, you can install it in memory using the
package manager of the liveCD if its not included, otherwise install it on
your linux machine first, and you are also going to need gcc (I think) and
the dependencies listed in the next section:
Build the book

You can build the pdf by cloning this repo and running make:

$ git clone https://github.com/hadley/ggplot2-book.git
$ cd ggplot2-book
$ make

If you use RStudio, you can press Cmd/Ctrl + Shift + B to run make.



Installing dependencies

To successfully build this book, you'll need R package development
prerequisites

, pandoc and pandoc-citeproc ,
potentially the Inconsolata font
, and a number of R
packages. The CRAN packages we depend on are listed in the DESCRIPTION, so
you can install them quickly via devtools
:

devtools::install_deps("path/to/ggplot2-book", dependencies = TRUE)

There are also a couple GitHub packages which we depend on:

devtools::install_github(c("adletaw/captioner", "hadley/bookdown"))

They spin.  Thanks for trying.

How is your disk partitioned? /dev/sda1 may not be the
damaged partition.

As someone else mentioned, how is your disk partitioned?  You are
checking sda1, but are there other partitions/filesystems on your disk?
 You should confirm that it's not actually a different filesystem that
is failing.

Re-seat all cables and connectors.

Confirm all fans are operating.

Swap power supplies.

Swap disks.
