Beyond the Barricades in Ukraine: A Photo Tour of Maidan

Euromaidan PR

Kyivis relatively calm now, so it’s just the right time to study Maidan in detail. Almost everybody has heard that word, but not everybody imagines how everything works here. Now the protesters occupy Kyiv’s center – Maidan Nezalezhnosti square, almost all of Khreschatyk (the main street), European square and some of the adjacent streets. A few administrative buidings have been captured; in them, heating and medical help centers have been established, as well as stations for accepting and redistributing clothes and other items. There are hundreds of tents on the streets, in which the activists that have come to Kyiv from all over the country live.

Amazon EC2 instances are the fundamental building block for your computing needs in the AWS cloud. You can think of instances as virtual servers that can run applications. Amazon EC2 M3 instance sizes and features are:

Instance   Family	Instance Type	Processor   Architecture	Vcpu	Memory (GiB)	Instance   Storage (GB)	Price/hr Linux / Unix   Usage
General Purpose	m3.medium	64-bit	1	3.75	1 x 4 SSD * 6	$0.113

Session Hijacking

TCP session hijacking is when a hacker takes over a TCP session between two machines. Since most authentication only occurs at the start of a TCP session, this allows the hacker to gain access to a machine.

A popular method is using source-routed IP packets. This allows a hacker at point A on the network to participate in a conversation between B and C by encouraging the IP packets to pass through its machine.

If source-routing is turned off, the hacker can use “blind” hijacking, whereby it guesses the responses of the two machines. Thus, the hacker can send a command, but can never see the response. However, a common command would be to set a password allowing access from somewhere else on the net.

A hacker can also be “inline” between B and C using a sniffing program to watch the conversation. This is known as a “man-in-the-middle attack”.

A common component of such an attack is to execute a denial-of-service (DoS) attack against one end-point to stop it from responding. This attack can be either against the machine to force it to crash, or against the network connection to force heavy packet loss.   

Sticky Session

What does the term sticky session mean in a web-farm scenario?

Sticky session refers to the feature of many commercial load balancing solutions for web-farms to route the requests for a particular session to the same physical machine that serviced the first request for that session.

Why would you use a sticky session?

This is mainly used to ensure that a in-proc session is not lost as a result of requests for a session being routed to different servers.

What is the potential disadvantage of using a sticky session? 

Requests for a user are always routed to the same machine that first served the request for that session, sticky sessions can cause uneven load distribution across servers.

Magento Websites And Store And Store View

Magento is the ability to manage multiple websites and stores from one back-end.

1.It allows store owners to manage stores in different Urls.
2.Display the same products in different languages on the same URL, along with a variety of other setups.

If you will only be selling your products from one URL in one language you will not need to use this functionality.

but the ability to easily expand into additional languages makes Magento scalable as your business grows out of your home market.

Websites

A website is made up of one or more stores which share the same customer information, order information and shopping cart. This is a very broad term that can be adopted to define the unique needs of individual merchants.

Stores
Stores can be setup in a variety of ways, but remember that if they are part of the same website they will share certain information.

Store Views
Store Views are mainly used for different languages, so if you wanted to have a store displayed in English and Spanish, for example, you could create the store once and create two different store views for that store.
