Is it possible to obtain the status of Bacula backup system Director in some parseable format?
It looks like the human-readable representation (one you can see when using bacula-console) is formed on the director side during the TCP control connection.
In what language? The easiest way would be to invoke bconsole and send command as stdin, then parse stdout and stderr.
Bacula has interactive mode in bconsole, but if you know commands in advance, this is not an issue.
You can also pull directly from the database, depending on your needs.
Example:
mysql> select JobId, Name, JobStatus from Job ORDER BY JobId DESC Limit 10;
+--------+-------------------------------------+-----------+

I am trying to build my custom ROS services. They are inside a another parent package
the structure is as follows:
|--catkine_ws
| |--src
| | |--Parent
| | | |--CMakeLists.txt
| | | |--package.xml
| | | |--ChildA
| | | | |--CMakeLists.txt
| | | | |--package.xml
| | | | |--srv
| | | | | |--SomeService.srv
| | | |--ChildB
The packages are building correctly and I am able to use them in other nodes and packags.
however when I try to use rossrv list the custom services do not appear. I think that this is causing some issues when I try to build my Simulink controller and it cannot find the service message definition.
Does any one have any idea what is going on?
I was able to fix the problem, while not obvious, the solution was rather simple. I had to change the slightly change the structure of the package by making the parent package a meta package then do some handling to make sure that the sub packages still had access to the cmakes to locate my external packages.
I have two nodes "A" (primary) & "B". Each node have 3 resources. On node "B" i replace disks and after that i add each resource as secondary. Two resources successfully connect and sync, but with one resource i have issue. When on node "B" i stop this resource, node "A" shows
lv1 role:Primary
disk:UpToDate
b.host connection:Connecting
When i starts this resource on node "B", node "A" shows:
lv1 role:Primary
disk:UpToDate
b.host connection:StandAlone
and node "B" shows:
lv1 role:Secondary
disk:Inconsistent
a.host connection:Connecting
I try everything, remove/add resource, metadata on node "B", remove data, rebuild raid drbdadm connect lv1 --discard-my-data etc.
One difference between worked an broken resources is This node was a crashed primary, and has not seen its peer since

Any ideas how i can fix it?
UPD: Find new differences a kernel: drbd lv1/0 drbd1 b.host: The peer's disk size is too small! (999671944 < 1000196216 sectors)
In my case on node "A" (primary) i have LVM, on node "B" i have MDRAID. This differences give me difference in resource size in 524 272 sectors. What i do to save my data. I run both resources in primary mode, mount and copy data from "A" to "B", then i rebuild node "A" to MDRAID and sync resources.
I am finding trouble in why my query in secondary indexed column in cassandra getting rpc timeout.

Request did not complete within rpc_timeout.
Here we can see that the query on secondary index column host gets succeeded but the similar query on service_type gets rpc_timeout error.
I am not able to find the reason behind it why it rpc_timeouted in this query.
select * from service_hubs where service_type='darknetdb';
Thanks
I am trying to avoid using inline HTML to get tables working in my MD file. I have Markdown Preview and Table Editor installed via the package installer, and multimarkdown installed via homebrew, but I can't get the following text to display as a table:
| Left align adsf | Right align | Center align |
| :--------------- | ----------: | :----------: |
| This | This | This |
| column | column | column |
| will | will | will |
| be | be | be |
| left | right | center |
| aligned | aligned | aligned |
When I "Markdown Preview" it just displays like this:
| | | Left align adsf | Right align | Center align | | --- | --- | ---------------- | ----------- | ------------ | | | | ---------------s | ----------- | ------------ | | --- | --- | :--------------- | ----------: | :----------: | | | | This | This | This | | | | column | column | column | | | | will | will | will | | | | be | be | be | | | | left | right | center | | | | aligned | aligned | aligned |
I have switched the file type to MultiMarkdown (lower right portion of ST2 screen)
I have searched, and it appears some people have a build system, or other approaches I have been unable to get going. What am I missing? If a build system is needed, how do I set up one? I am mainly interested in viewing this in HTML, but wouldn't be opposed to other ways....
If you switch the parser to github, it'll work just fine.
Go to Prefrences > Package Settings > Markdown Preview > Settings - User and paste this code:
{
"parser": "github"
}
"If a build system is needed, how do I set up one?"
In OS X I would strong suggest getting the excellent Marked.app and then setting up a new build system in ST containing this trivial code
{
"osx": {"cmd": ["open", "-a", "Marked", "$file"]},
"selector": "text.html.markdown"
}
Then when you 'build' a markdown file (Cmd+B) you will get a preview generated in Marked.
Easy and elegant and well worth the cup-of-coffee price of Marked to avoid all the hassle of the plugin approach.
I want to store a simple active record object using memcached. I know I need to first convert the object to JSON before saving it to memcached my question is how I can pull it out again, deserialize it and use it as an activerecord relation. Do I have to make a custom parser the JSON or am I overlooking some drop dead easy solution?
The active record object looks like this:
+------+-----+-----------+---------------------------------+---------------------+-------+
| id | ppl | exclusive | name | price | spots |
+------+-----+-----------+---------------------------------+---------------------+-------+
| 8948 | 12 | false | 12 Bed Mixed Dorm | 9.0000000000000000 | 12 |
| 8947 | 10 | false | 10 Bed Mixed Dorm | 9.5000000000000000 | 10 |
| 8946 | 6 | false | 6 Bed Mixed Dorm | 10.0000000000000000 | 6 |
| 8945 | 4 | false | Basic 4 Bed Mixed Dorm | 10.0000000000000000 | 4 |
| 8944 | 2 | true | Twin Private Shared Bathroom | 12.0000000000000000 | 1 |
| 8943 | 1 | true | Standard Single Private Ensuite | 15.0000000000000000 | 1 |

You shouldn't don't need to worry about the serialization -- in almost all cases, this can be handled for you:
#Gemfile
gem install dalli
#config/environments/production.rb
config.cache_store = :dalli_store, '127.0.0.1' #use memcached
#Get id 1245 from model_names
Rails.cache.fetch("ModelName#1245") do
ModelName.find(1245)
end
