This Week I Learned -

VNet peering is a mechanism that connects two virtual networks in the same region through the Azure backbone network. Once peered, the two virtual networks appear as one for all connectivity purposes. They are still managed as separate resources, but virtual machines in these virtual networks can communicate with each other directly by using private IP addresses. The traffic between virtual machines in the peered virtual networks is routed through the Azure infrastructure much like traffic is routed between VMs in the same virtual network. Some of the benefits of using VNet peering include:
- A low-latency, high-bandwidth connection between resources in different virtual networks.
- The ability to use resources such as network appliances and VPN gateways as transit points in a peered VNet.
- The ability to connect a virtual network that uses the Azure Resource Manager model to a virtual network that uses the classic deployment model and enable full connectivity between resources in these virtual networks.

Last week, it was revealed that over 500 million Yahoo! accounts were breached. While the account-holders' passwords themselves were only retrieved in encrypted form, it appears as though some if not all the password hints (questions about something private to the account holder and the answers) were retrieved in clear text, unencrypted. Back in Oct 2013, Adobe experienced a nearly identical compromise in which the hackers obtained the encrypted passwords and password hints (in clear text) for over 38 million of its users. One year later, when the social media company Buffer suffered a major API-related breach, it was relatively confident that at least part of the attack on its infrastructure was inspired by data gathered during the Adobe breach. At the root of the issue is a problem every Internet user knows about (but also doesn't do much about): shared passwords - ProgrammableWeb

* There is no long-term capital gains (LTCG) tax to be paid if Arbitrage funds are held for over a year and sold thereafter.

Debt funds qualify for LTCG if held for three years, after which they are taxed at 20 per cent with indexation. Over the past three- and five-year periods, arbitrage funds have delivered over 8 per cent returns. Investors may find returns from this category suboptimal but this owes to their lower risk profile.
