Twitter Web Client Inline Image Removal

If you're a heavy user of the Twitter web client like me then you'll find the new inline preview feature extremely intrusive as it breaks up the timeline too much. If I wanted to use facebook or linkedin then I'd be using facebook or linkedin. Having said that, cards in Twitter are great and the ability to preview media before jumping off site is really cool - but it should be my choice, not have everything foisted on my timeline.

That the mobile client allows for this with a setting is even more annoying.

So here's the fix. This only works in Chrome but I'm sure an enterprising person could do something similar for Safari and Firefox using the same CSS. Pull requests to update instructions for other browsers are of course very welcome.

Updates

A quick "how to" on what you need to do to both setup AND recover a single-server PostgreSQL database using WAL-E

WAL-E: https://github.com/wal-e/wal-e
Assuming Ubuntu 12.04 LTS ("Precise")
We'll be using S3. Make sure you have an IAM in a group with GetObject, ListBucket and PutObject on the bucket you want to use (and that it's not public).

Setup:

These packages:

Previous versions used homebrew to install the various versions. As suggested in the comments, it's better to use pyenv instead. If you are looking for the previous version of this document, see the revision history.

$ brew update
$ brew install pyenv
$ pyenv install 3.5.0
$ pyenv install 3.4.3
$ pyenv install 3.3.6
$ pyenv install 3.2.6
$ pyenv install 2.7.10

$ pyenv install 2.6.9

A simple Ghostscript command to merge two PDFs in a single file is shown below:

gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=combine.pdf -dBATCH 1.pdf 2.pdf

Install Ghostscript:

Type the command sudo apt-get install ghostscript to download and install the ghostscript package and all of the packages it depends on.

	* test xmpp bot behavior with different servers, measure throughput and reliability.
	* figure out numbers for prosody, nothing seems to be published at the time of writing
	* the goal was _not_ to push the servers to their limits, so the test environment was not highly optimized.

	* macbook pro hosting ubuntu raring on vmware fusion.
	* communication flow: xmpp client (osx) > xmpp server (ubuntu) > xmpp bot (osx).
	* client opens 20 connections to server and pumps 150 iq stanzas (similar disco#items) to bot. this is being repeated 40x.
