I'm conducting a study and I need to store some data. I found an open source data scraper and parser online: https://github.com/hicsail/materials
I've followed some instructions (some of which but not all came from here) and
installed Postgres, created a docker-compose.yml file, and created a config file:
Above is the config file, and this is the .yml file
I started by going into the pgAdmin folder and running "docker-compose up", after which, this was the result:
I'm not sure if the "no privileges flag" means anything. Anyway, after this, I opened up a localhost:5050 in my browser and logged into pgAdmin.
I named the database "materials" as this was what it was supposed to be named.
Same thing with the username and password; both were named "root". However, when I run the command to parse the data, I'm getting this error:
I've been stuck on this for a long time now, and I can't seem to find any solution. This is running in a python2.7 conda environment, as per the requirements. These were the other installed libraries (I'm not 100% sure those were the exact versions, but I tried to get them as close as possible).
psycopg2==2.7.3.1
requests>=2.20.0
SQLAlchemy==1.0.9
wheel==0.24.0
If I need to clarify anything please let me know.
Thanks.
I found an answer for this. I had to go into services, then to postgres, and stop it from running. I then had to kill the port "5432" and run it again.

We are having trouble deploying our Google Appengine application. We get the following error message
from the indicated deployment command at the Unix shell prompt.
/home/leffstudent/appengine/bin/appcfg.sh update ~/u3/web/war -p proxy.wiu.edu:8080

Attempting to open it in your browser now.
Unable to open browser. Please open the URL above and copy the resulting code.
Please enter code:
There is no browser on this computer, a Linux virtual machine, used as the programming opportunity for the School of
Computer Sciences. We simply use putty to log in.
I cut and pasted the address and entered into Chrome into the computer that has run putty. I get the code in that browser. I cut that and tried to paste it back
into the browser. NO luck.
I get
"java.net.ConnectException: Connection refused"
(This has been difficult because this Putty does not seem to have menu items for cut and paste.)
I tried about seven times. Several times, I also tried simply typing the code in carefully. No luck.
The graduate student on the project also tried themselves--no luck!
Thanks for any insight. In particular, it seems I should I ask the system administrator who set up the disk slice with our School of Computer Sciences'
server for a "browser." What should I specifically ask for? I did not see any documentation of what the google appcfg.sh program is doing when it tries to "open it in your browser now."
We have a project on which five people have worked over several year time frame that is dead in the water because we can no longer
deploy.
I'm not sure why the code isn't working - it should. As a work-around why not:
push the code to a git repo (e.g. bitbucket)
pull it to a machine that does have a browser
Set up the browser-machine to run GCloud under the account you're hoping to authenticate with
Deploy from there
We've just updated Nagios from 3.5.x to the current version (4.0.7) and subsequently added a new host for monitoring.
The new host shows as 'Down' in Nagios, and this seems to be related to the fact that pnp4nagios is not logging performance data (the individual checks for users, http etc are all find).
Initially there was an error that the directory
/usr/local/pnp4nagios/var/perfdata/newhost.com
that contains the xml setup and rrd files for the new host was missing), so I manually created this directory, but now it complains that the files are missing.
Does anyone know the appropriate steps to overcome this issue?
Thanks,
Toby
PS I'd tag this 'pnp4nagios', but that tag doesn't exist and I can't create them
UPDATE
It's possible that pnp4nagios is a red herring/symptom. Looking more closely I realise that Nagios actually believes the host is down, even though all services are up. The host status information is '(Host check timed out after 30.01 seconds)'...does this make any more sense?
It's indeed very unlikely that pnp4nagios has something to do with your host being down. pnp actually exports output and performance data to feed the rrd database and xml files (via npcd module or evenhandler command).
The fact that nagios reports the host check timed out after 30 sec means that :
- you have a problem with your host check command, please double-check the syntax
- this check command times out after a certain timelapse (most likely defined in nagios.conf) because the plugin was still running.
I'd recommend running this command from the server's prompt. You want to do something like :
/path/to/libexec/check_command -H ipaddress -args
For example:
/usr/local/libexec/nagios/check_ping -H 192.168.1.1 -w 200,40% -c 500,80% -timeout 120
See if something might be hanging. Having the output would be helpful.
Once your host check returns correct output and performance data to nagios, pnp will hopefuly do the rest.
In the unlikely event it helps anyone, pnp4nagios was indeed a red herring. The problem was that ping wasn't enabled for the host being checked, and this is the test for whether a host is up or not. Hence this was failing, despite other services being reported as working.
I used to install Neo4j 2.0.0-M05 as windows service, this worked great. With 2.0.0-RC1 it doesn't any more.
Intro
With 2.0.0-RC1 I can download an installer. Seems that this installer does not have an option to install Neo4j as service. Also it doesn't let you set some directories (I like everything in C:\apache\neo4j); some stuff is being stored in my user directory. And it doesn't remember the location of the database. So that leaves the zip as only real alternative, though the zip file comes in only one version while the installer comes in 32bits and 64bits??
Anyway now trying with the zip package I have to run a .bat file just as before (i'm used to this). But when i try install, i get:
C:\apache\neo4j\bin>Neo4jInstaller.bat install
"WARNING: this installer is deprecated and may not be the optimal way to install Neo4j on your system."
"Please see the Neo4j Manual for up to date information on installing Neo4j."
Press any key to continue
Two things are weird.
It's the only option to install neo4j as service, so how can it be deprecated?
Press any key to continue only response to the enter key.
Problem
Continuing on the the real problem:
Press any key to continue
[SC] CreateService SUCCESS
[SC] StartService FAILED 87:
The parameter is incorrect.
Workaround
I removed the .bat files from 2.0.0-RC1 and copied the 2.0.0-M05 bat files over to the new version. It seems to start the new version without a problem.
Thanks for the feedback. There are open github issues related to much of this, which we'll clean up before going to GA. Even then, your conclusion is correct, that for now installation as a service requires downloading the .zip distribution. We'll make that more clear in the download page.
Generally, installation as a windows service is something we're working to improve. I'd love to chat with you a bit about your particular deployment scenario. Please drop me a line at andreas#neotechnology.com.
Best,
Andreas
My plan is to prepopulate a database on a virtual device and then include database in the distribution of my app.
However, I can't find the database file.
Is it on my hard disk some where?
How do I get it?
I tried connecting using adb, I did an "ls" and then got really scared by this obscure list of directories:
sqlite_stmt_journals
cache
sdcard
etc
system
sys
sbin
proc
init.rc
init.goldfish.rc
init
default.prop
data
root
dev
Even when I cd over to /data/data/your.package.here/databases I still do not have access to the actual database file. I can't use sqlite3 or do a pull on it. Is there a way to change permissions?
This works fine on my emulator, but fails on the actual device
adb pull /data/data//databases/mydb.db .
It should be in /data/data/your.package.here/databases, where your.package.here represents the package associated with your application, as defined in your AndroidManifest.xml file.
If you want to navigate to your database (which is located /data/data/your.package.here/databases), make sure you are a root user while navigating shell. To do so, type "su" once you enter the command prompt. When you are a root user, you can navigate wherever you want.
The blog post below gives a good solution of how to find and access your database. The post talks about using busybox, which provides useful utilities at the command line, to find your database and gives a few useful examples on how to use sqlite3 to access the DB and tables.

I've got the following settings in my postgres conf:
log_destination = 'stderr'
redirect_stderr = on
log_directory = '/tmp/psqlog'
log_statement = 'all'
And yet no logs are logged. What am I missing here? There is reference on the internet to a variable called "logging_collector", but when I try and set that, postgres dies on startup with a FATAL: unknown variable.
This is on MacOS 10.4.
Ta.
I believe that you need to change log_destination to "syslog" or a specific directory. Output that goes to stderr will just get tossed out. Here's the link to the doc page, but I'll see if I can find an example postgresql.conf somewhere http://www.postgresql.org/docs/8.2/static/runtime-config-logging.html
This mailing list entry provides some info on setting up logging with syslog http://archives.postgresql.org/pgsql-admin/2004-03/msg00381.php
Also, if you're building postgres from source, you might have better luck using a os x package from Fink or MacPorts. Doing all of the configuration yourself can be tricky for beginners, but the packages normally give you a good base to work from.
