Well ... just because YouTube tells you that you're "not signed in" ... doesn't mean it doesn't know who you are. I watch lots of Ubuntu and Android related videos, so that one "recommended for you" spot among the many totally unrelated stuff (which are all similiar to the one I just watched) means YT knows exactly which user is sitting before the computer. Even though I've not signed in.


(Update: furthermore ... if you're signed in to your Google account, but not in YouTube ... and you visit any YT page and hit the "Upload" button on one of them, then you get automatically signed in. I guess it's just a matter of time before YT gets fully integrated with all the other Google services ... meaning that there'll be no separate "Sign in" button for YT either.)

This is going to be an anti-commercial. :-)
If you're ever going to publish a website at a hosting company, I strongly suggest that you do NOT choose Mochahost (www.mochahost.com). Their service is poor as is their customer service. I've never met a company like this and hopefully never will again. :-(

P.S.: and if MH would consider sueing me over this post ... I'm happy to provide proof for my "accusations". :-P

Well, getting awards is really just a question of money. And even if all the high-profile tech magazines voted for them as the service provider of the year ... it still wouldn't change my personal impressions of the service my company got from them.

Btw. there seems to be no way to change the visibility of a post after you published it. What a pity. This seems to be such a basic thing ... I wonder why Google didn't put it in Google+ the very first time they went live with it.

That's odd. There's somebody who has me in her circles ... but if I click on her name it says "Profile not found". :-o Is this a glitch in Google+ or what? Did she delete her Google+ profile already and her showing up in my Circles screen on the "Have you in circles" tab in the "Not yet in your circles" list is just a bug? :-o

From Lithuania with electric love. So cool and simple it may even work!
And the dudes need only $100K?! To achieve what took Segway $175M (to fail)? That would be quite a feat

Ubuntu vs. Filesystem Hierarchy Standard

The official Installation Guide claims that "Ubuntu adheres to the Filesystem Hierarchy Standard for directory and file naming".
https://help.ubuntu.com/12.04/installation-guide/amd64/directory-tree.html

This is plain and simple marketing bullshit. Most linux distributions "adhere" to FHS, when it comes to directory and file naming. The "naming" part is approx. 1% of FHS! So putting FHS in the same sentence with Ubuntu is simply bs.

Following the FHS definitions of each directory is an entirely different matter. Ubuntu has the bad habit of putting configuration data where it does not belong. :( Tons of packages require you to put local configuration somewhere in /usr/share, whereas FHS clearly states that:

"/usr is the second major section of the filesystem. /usr is shareable, read-only data. That means that /usr should be shareable between various FHS-compliant hosts and must not be written to. Any information that is host-specific or varies with time is stored elsewhere."

http://www.pathname.com/fhs/pub/fhs-2.3.html#THEUSRHIERARCHY

What is there not to understand? :-o
You can put configuration into /etc, you can put it into /var (although it is not advised, but if for some reason /etc is not good enough for you, then the next best thing would be /var), but never into /usr.

Let's see what FHS says about /var:

"/var contains variable data files. This includes spool directories and files, administrative and logging data, and transient and temporary files.
(...)
/var is specified here in order to make it possible to mount /usr read-only. Everything that once went into /usr that is written to during system operation (as opposed to installation and software maintenance) must be in /var."

I'm used to such ignorance from Microsoft (a company famous about bending and corrupting each and every standard they put their hands on), but not from a company in the linux world.

Unfortunately this is nothing new. Ubuntu package developers/maintainers have been doing this from day one (as far as I can remember). And I get angry every time I've to set up a new server and migrate configuration (custom settings) from another server. The only thing you can do is to put a very distinctive comment/string in each modified configuration file and when it comes to looking up each customized config file, you can do a text search (something along the lines of "find ­­­-L targetdir ­-type f -exec fgrep -qs 'someuniqcomment' '{}' \; -print") in all possible involved directories. And since /usr/share can be several gigabytes, including it in this text search will go through thousands of binaries as well, which should be totally unnecessary. Obviously there're ways (possible optimizations) to speed up such a search, but why not do it right and put configuration in /etc in the first place? :(

And hiding various local config. data in /usr/share has the other obvious drawback that backing up /etc is not enough. On my Debian servers a regular backup of /etc (and a few other things like package selection, etc.) is all I need to recreate the same configuration on a freshly installed server. On an Ubuntu server you've to find and backup the customizations in /usr/share too.

I'm starting to believe that leaving Ubuntu is the best possible option here. Maybe I should just stick with Debian for all purposes.

It's good to know and keep in mind: Google+ remembers the visibility of your last post/share and uses it in all your future shares as a default. I used to post only to my extended circles, but there was one single thing that I wanted to share publicly. And ever since all my posts/shares got public since I didn't notice that the default visibility changed from "Extended circles" to "Public". :-( Not that I shared anything personal ... but still. It's a bit annoying.
