What is LiveRebel about, dude?

LiveRebel 2.0 is an out-of-the-box solution to end slow, inefficient production deployment processes that often happen at 3 AM by overworked operations staff.

With LiveRebel, now every single update is:

• online
• transactional
• 100% reversible
• fully automated
• instantaneous in case of minor updates

What does this mean to you?

It means that when something does go wrong, as it inevitably does, there is a panic button to press that will make it all better.

It means that because your application stays online, your updates can be done during the day and businesses don’t have to hide from their customers or lose a cent of revenue.

LiveRebel 2.0 now supports multiple update strategies:

1. Hotpatching strategy updates the application instance in-memory, without pausing for a moment.
2. Rolling restart strategy takes each server down at a time for update, but the users don’t notice a thing as they are automatically routed to instance with their session.
3. Offline update strategy will take all servers down and do a clean restart, the user requests will still resume when servers are up.

How to install it?

Nice walk-through is available here , but it’s simple. Just 3 steps:

• Download the archive. It comes with 90 day evaluation license.
•  Unzip it
•  Run the command center

Here’s is a very short video, that shows the install process:

/The Troll Dad/

I was inspired by Lydia‘s talk during FOSDEM to share some thoughts about using trolls as a marketing asset.

Define

I am sure you know what is a Troll, but anyhow there it is, directly from UD:

A dumbass who makes idiotic posts in message boards newsgroups for the sole purpose of pissing people off, often lacking in intelligence. Sometimes compared to people who pass you by on the sidewalk then grab you in inappropriate places.

More “official” definition, can be found here at Wikipedia.

Trolls in action

I know couple of companies that are feeding the trolls, yes they have special policy and people to do that.

The reason is quite simple:

• More trolls
• More “discussions”
• More page views,
• More banner views,
• More money in company’s pocket.

Trolls & flame-wars

I know some companies that are publishing flame-war blog posts to attract more trolls why?

• More trolls = more content
• More content ==  more developers to fight for their positions
• More developers == more leads
• More leads == More sales
• More sales == More money in company’s pocket.

That’s it.

пидорась == faggot
IT отдел == IT crowd/department/section

The past
I remember when I was younger and I was writing some bytes for living. I still know that there are just 10 types of people in the world: Those who understand binary, and those who don’t.

WTF?
I was wondering all my life why the heck we need a marketing and community management droids at our team. We create a kick-ass products that we can sell them via our web-page using 33 lines of HTML code an an Paypal account.

I am on the dark side of the force now and I know why.

The truth in 5 points*

If there is no marketing droids:

1. Less people know about us – our clients are our friends and peers and visitors from Google are welcomed too.
2. 1 = Less money – well, I don’t have to explain this, do I?
3. 2 = No salary++
4. 3 = No beer money NOR I just got an invitation to work for another company that has a great marketing department.
5. R.I.P  GPWGFTCCW (Great Product with great functionalities that can change the world.)

If there is no community management guys:

1. No community around us = We have to test our product by ourselves in any possible OS, CPU, RAM, ….
2. No community around us = How to know what to improve and what the clients really need from our products?
3. No community around us = How to get ideas for new products?
4. No community around us = How to find someone that will tell you honestly “You’re wrong”
5. No community around us = How to find someone who will help you with documentation, bug hunting, beer drinking, and to cheer you up – “You’re good. I love your product.”

* I am so sorry, but someone should change the ordered list to start from 0/zero/. Starting from 1 is so lame.

The Idea
The idea is to control slides only by moving my hand, without any devices in it.

The plan:
0. My web-cam should detect my move
1. After detection an event should be triggered
2. As a final action the slide should move to the next one

Motion detect

$ git clone https://github.com/sackmotion/motion.git
$ cd motion
$ ./configure
$ make & make install

Configure it

Motion comes with a great almost working config file, so just copy it to make it “official”:

$ cp  /usr/local/etc/motion-dist.conf /usr/local/etc/motion-dist.conf

Open it, search for those values, edit them and read what are they for:

;on_event_start value
event_gap 60

to become:

on_event_start xdotool key Right /OR xdotool search "Mozilla Firefox" windowactivate --sync key --clearmodifiers Right/
event_gap 1

Event triggering

You may need to install xdotool using your package manager. This tool allows you to emulate keyboard action in different combinations, but I will need to emulate pressing the right arrow key.

How it works:

When web-cam detects movement an event emulating ‘right arrow’ key is pressed. Since I am using HTML5 DZslides from here, this allows me to move to next slide only with moving my hand in front of my webcam.

Run

Run it and move your hand in front of your camera. You may want to turn on the logging to see the motion detection and the event detection if it’s not working at first.

$ motion

If you have any questions, please let me know.

Rust is an experimental, concurrent, multi-paradigm, compiled programming language developed by Mozilla Labs. It is designed to be practical, supporting pure-functional, concurrent-actor, imperative-procedural, and object-oriented styles. /wikipedia/

How to install it on your Gnu/Linux box?
Pre-requirements:

• g++ 4.4 or clang++ 3.x
• python 2.6 or later
• perl 5.0 or later
• gnu make 3.81 or later
• curl

Download latest version (0.2 pre at the moment)

git clone https://github.com/mozilla/rust.git

Make it

$cd rust
$./configure
$ make & make install

Note:

It takes a lot of time and you do need an active internet connection during the compiling process.

Hack
Open your Geany or your favourite IDE and write this:

use std;
 
fn hello_world(name: str) {  
	let greetings: str = "Hello World, "+ name +"! and Здравей свят! and 您好，世界！";
	std::io::println(greetings);
}
 
 
fn main(args: [str]) {
	hello_world(args[1]);
}

Save it as helloworld.rs

Compile it

$rustc helloworld.rs

Execute

$./helloworld.rs Bogo //put here your name

What to do?
0. Install the Zemanta plugin from Firefox repo.
1. Open your wordpress blog and start writing something. Let’s say about SOPA and how dangerous it is for the freedom in general.
2. You will see some cool link suggestions to include into your post, what I did.

3 Also you will notice the new Zemanta block next to your writing area containing images and news similar to the topic you are writing for.

4. You can add your own Blog to Zemanta via ‘My sources’ menu and to use it as an source and you can link it with easy. You can add other sources as well.

Cons:
- You must using your ‘Visual’ (a.k.a WYSIWYG) mode to compose message. Otherwise Zemanta will not work at all. This is a problem for me, but I may switch back.

- It’s not working well if you have couple of topics, like the current one. I am talking about Zemanta and SOPA. The content for SOPA is missing
- it actually sends parts of my content somewhere via Internet to be analysed and this may be a security issue for business bloggers.
