I get eng.traineddata and spa.traineddata in this form:
cd /usr/local/share/tessdata
wget https://github.com/tesseract-ocr/tessdata/blob/main/eng.traineddata
wget https://github.com/tesseract-ocr/tessdata/blob/main/spa.traineddata
:::::::::::::::::::::::::::::::::::::::::::
allways I install languages with:
wget https://github.com/tesseract-ocr/tessdata/raw/master/eng.traineddata
wget https://github.com/tesseract-ocr/tessdata/raw/master/spa.traineddata
then allways tesseract work fine, but now this return 404
how I can fix?

I am trying to use ContextCompat class from the Android Support Library. I am using only CLI tools to build an app. So I figured I have to get a jar. I entered the following:
$ sdkmanager --list | grep extras

The problem is, I cannot see any jar files of the latest Android Support Library. What should I do to download it?
The folder /opt/android-sdk/extras/android/m2repository/com/android/support/support-v4/24.1.1 in my case contained about 2MB aar file, which contained classes.jar file, which I finally and ended up using. It is unclear what is the purpose of other low-size files in the other folders like 26.0.0.
I downloaded scala,unpacked it and copied to /usr/local/share
After that,I edited ~/.bashrc
export SCALA_HOME=/usr/local/share/scala-2.12.8
export PATH=$PATH:$SCALA_HOME/bin
Anyway,it does not work.
scala -version
Command 'scala' not found, but can be installed with:
sudo apt install scala
I could go for apt install but I don't get it what is wrong.

Editing .bashrc won't affect an already open shell. You could explicitly source it (source ~/.bashrc) to have it take effect, or open a new shell to reload it.
After configuring a standalone Concourse 2.4.0 per the instructions, everything seems to be up and running. However, when trying to run the "hello world" example, I can see the following error in the Concourse UI:
runc create: exit status 1: rootfs ("/volumes/live/a72f9a0d-3506-489b-5b9b-168744b892c1/volume") does not exist

--work-dir worker \

I'm wondering if the problem occurs since the "missing" directory is created in the directory specified in the "start worker" command, instead of at the actual root directory:
~/concourse# ls -la worker

Concourse is installed on Ubuntu 14.04:
uname -r

uname -a

For reasons that I still do not understand, it appears that if you specify the --work-dir value to be /opt/concourse/worker, then the worker will work with this kernel version without issue.
I was using a relative path to a worker directory within a dir in my user folder as my --work-dir value.
I have a yum repository I've set up where I store custom rpms.
I have no problem finding information about other packages that were built and stored in this custom repo.
#yum --disablerepo=rhui-us-east-rhel-server-1y,epel,epel-testing --enablerepo=customrepo install php53-pecl-xdebug
php53-pecl-xdebug x86_64 2.2.1-2 customrepo 132 k
No problem.
Now I drop somerpm.rpm in centos/repo/5/noarch, run createrepo --update . in this directory and try the same command, and yet it shows no results.
I tried running createrepo --update in the root of the repo as well, but that did not work either (I'm actually not sure where to run it and if it needs a repodata directory in each subdir).

I also tried adding the exactarch=0 flag to my repo config to ignore arch restrictions and this did not work either, it was a shot in the dark, since my rpm is noarch, it should show regardless.
# cat /etc/yum.repos.d/mycompany.repo
[mycompany]
name=mycompany custom repo
baseurl=http://config/repo/centos/5/$basearch
enabled=1
exactarch=0
I'm at a loss at this point. Usually createrepo --update does the trick, but for some reason it cannot find the new rpms.
repo]# find . -type f -name "*.gz" | xargs zcat | grep salt-minion
returns results as well, so it's definitely in the repo data.
yum clean all on the server I was trying to install on worked.
Also make sure to do createrepo --update on the specific subdir instead of the root of the repo.
I'm very (very) new to node.js, and also fairly green when it comes to server side configuration and coding. (I have a long history of client-side programming, most recently with Adobe Flex and ActionScript.)
Anyhow, I asked Rackspace (who manages a Linux server for me) to install node.js and node-postgres.
From the comments in the ticket, that installation went like this:
node.js

A little “Hello world” node.js example works fine (hooray!), but a simple Postgres example fails on the require('pg') statement, saying that the module cannot be found. I've looked on the server and can't find a pg.js file anywhere.
Any clue as to why the node-postgres build failed?
Install it globally:
npm install -g pg
You may need to become root, e.g. with
sudo npm install -g pg
