A thread at /r/linux sought out to reveal all the magic ways of increasing productivity under Linux (or other *nix based OS-es), and as most people I thought that there wouldn’t be much news here.
But I was wrong. So very, very wrong.
- disown – a way to disown a process, making it continue running in the background if you have to log out or close a long running session over ssh because you’re going somewhere, but want to keep the currently running process still running. If you’ve ever thought “why the fsck didn’t I run this under screen?”, then this trick is for you. This is a new future, and I’m proud to be a part of it.
- CTRL+r in bash – allows you to search your bash history buffer. I’ve known about this, I’ve just never picked up the habit of actually using it. Will do that now.
- ssh-copy-id – Appends your public key to the authorized_keys file at the destination computer.
- man ascii – the manual page entry for ascii contains an ascii table, right there in your terminal.
- xargs ‐‐max-procs and parallel – allows you to duplicate the functionality of xargs, but in parallel. Starts up all the processes at the same time, instead of starting them one by one.
Head over to the thread for other goodies such as a sudo alias for writing files when you’ve opened them without the correct permissions directly in vim.
When trying to find out why a particular ad campaign isn’t being delivered as you thought it should, the DFP documentation indicates that you should apply “google_debug” to the URL and a new window show pop up with the debug information. After digging through documentation and searching Google for a couple of hours without getting this to work, I finally found the relevant part of the DFP documentation.
Here’s the kicker: in the new, improved ad handler (gpt.js) you’ll have to append “google_console=1” in your URL, then press CTRL+F10 to launch the debug console. No google_debug, no google_pubconsole, just google_console and CTRL+F10.
Hopefully this will help someone trying to find out by searching for relevant terms.
After upgrading to OpenX 2.8.7 from 2.4.1 our statistics suddenly seemed to have vanished. Debugging an issue like this isn’t just straight forward, but after digging through google searches, wiki pages at OpenX and, well, reading the source (brrrrrrrrr), I think I’ve nailed it.
After upgrading to 2.8.7 the DeliveryLog plugin didn’t get installed – which meant that no delivery / clicks / impressions were logged. After discovering that this had been moved to a plugin I tried simply unzippping the plugin and copying the files to the plugins/-directory. This seemed to make OpenX recognize the plugin if I went to “groups” in the plugin menu, but not under the “plugin” menu. Another problem was the fact that it didn’t actually log anything, which could be considered a problem.
All the Google searches had shown that OpenX had changed the logging format to a new table structure (named buckets), but they don’t provide of restoring / creating the bucket tables if they don’t exist, and they don’t give any error about the bucket tables missing if the plugin doesn’t load. I couldn’t find anything at all about how the tables should look and which tables should be installed, but I finally tried to simply install the plugin through the web interface (Log in as Administrator -> Select Plugins in the top menu) by uploading the zip file directly, and then FINALLY the post install script ran. That created the tables (I’ll dump the definitions later if someone needs them), and after reloading the ads the bucket tables started getting values.
Now we’ll just have to hope that they actually gets aggregated into something useful as well..
PS: I’m less than impressed by the OpenX upgrade procedure, it always seem to fsck up some detail that leaves your installation in limbo, without being able to detect that something has gone wrong and provide a way to resolve the issue. I understand that they need to – and want to – focus on their pay product, so well, I’ll keep having to fix things manually for a while, but Google’s Doubleclick for Small Businesses may see a new customer soon.
