QUESTION
I am getting issue as -
...ANSWER
Answered 2020-Nov-26 at 11:20This function was introduced in libpq
in 9.5, so your psql
from v12 must by mistake try to load the libpq
from version 9.2, which causes this linker error.
You can try to change your shared library search path so that doesn't happen, but usually the better solution is to remove the 9.2 installation. The operating system packages and the PGDG packages don't work together well.
QUESTION
I have 2 CSV files (each of them have more than 1000 lines) like below:
urls.csv
...ANSWER
Answered 2020-Feb-27 at 18:36The reason it stops is that you actually consume (i.e. read) all the second file in the inner loop and then in the second iteration (i.e second line of the first file) the inner loop does not actually run.
Two possible solutions - 1. Use pandas and read the files as dataframe 2. Make sure you open and read the second file in the inner loop \ go back to the beginning of the file

I am trying to create an ec2 instance using boto3:
...ANSWER
Answered 2018-Feb-08 at 17:17You are launching the EC2 instance into a subnet of a VPC and so you have to supply the subnet ID. AWS can then infer the VPC, if needed.
In boto3, supply the NetworkInterfaces parameter when calling create_instances, for example:
QUESTION
I linked a machine through spacewalk to a few repo's including wandisco to get SVN to the latest version, as well as epel, and have ran into weird problems. Yum can't find a public key for updating rubygem-json-2.0.2-2.el7.x86_64.rpm
, which it says is coming from the base package.
However I have the key at /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
. I have been able to update all other packages explicitly like yum update subversion
or yum update perf python-perf
.
rubygem-json-2.0.2-2.el7.x86_64.rpm
just doesn't want to play nice. I tried explicitly importing GPG keys like rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-7
and rpm --import http://opensource.wandisco.com/RPM-GPG-KEY-WANdisco
, but this doesn't change anything.
I understand rubygem-json-2.0.2-2.el7.x86_64.rpm
is available from http://mirror.centos.org/centos-7/7/opstools/
(not just the base), but I am under the impression these use the same GPG key.
I am stuck right now. Yum says I need a key with an Header V4 RSA/SHA1 Signature, key ID 51bc2a13
, but I don't know what to do with this information.
ANSWER
Answered 2017-Dec-12 at 19:52The CentOS OptTools uses a different signing key.
Looking at OPS Tools Repository, there is centos-release-opstools-1-4.el7.noarch.rpm
that contains the following repository information.
QUESTION
This one has me scratching my head:
I added a repo to my cobblerd box, which was otherwise a happy CentOS7 cobbler server for a few small repos:
...ANSWER
Answered 2017-Dec-05 at 20:59As luck has it, I fell over the answer almost right after posting.
/var/cache/yum
has a redundant cache of usually-tasty repo data, but it even keeps the sour ones deleted long ago: I found a spacewalk-client25-6-x86_642
in there from the crafty attempt above, as well as the old spacewalk-client25-6-x86_64
one that it then refused to update.
I whacked that, chuckling malevolently, and resynched.
QUESTION
I wrote this class:
...ANSWER
Answered 2017-Aug-01 at 15:20Arrays are great for learning the concepts of coding and as such I endorse them much more than any other standard template library (when it comes to learning code).
Note:
It is wise to use a vector
however the reason schools don't teach this is because they want you to understand the underlying concepts behind things such as a vector
, stack
, or queue
. You can't create a car without understanding the parts of it.
Sadly when it comes to resizing arrays there is no easy way other than to create a new array and transfer the elements. The best way to do this is to keep the array dynamic.
Note my example is for int
(s) so you will have to make it into a template or change it to your desired class.
QUESTION
I am trying to run a Scala example with SBT to read data from MongoDB. I am getting this error whenever I try to access the data read from Mongo into the RDD.
...ANSWER
Answered 2017-Mar-05 at 03:02This error message is because you are using an incompatible library that only supports Spark 1.x. You should use mongo-spark-connector 2.0.0+ instead. See: https://docs.mongodb.com/spark-connector/v2.0/
