As a result, developers have to design with the dangers in mind and weigh that against the type and sensitivity of data stored in the client. At the moment, many development shops are not training their staffs to do that, says David Eads, founder of Mobile Strategy Partners, a mobile development firm that specializes in financial and insurance applications. In fact, he recently ran into a bank that used example HTML5 code for training developers that put data in permanent storage on the client system as opposed to temporary storage.
Instagram hopes 15 seconds will be better than six for social micro-video
Video on Instagram will allow app users to shoot videos anywhere from 3-to-15 seconds long—unlike the mere six seconds of Vine. Video allows for the use of multiple cuts,

Cable Is Key to ‘New’ Alcatel-Lucent
Whereas the telcos are migrating from voice-centric architectures to flat, all-IP networks, cable operators are set to go through a similar transition, but from video-centric to IP-centric networks.
Open Source is Not Just About Cost
While some in the past have associated open source with cost – it’s the cheaper alternative to proprietary approaches – that’s not the point anymore. The innovation model for open collaboration enables multiple competitive vendors to co-operate on core functionality and then compete on value added support and services.

Cisco Brings SON Innovation to Israel
Cisco’s SON technology is part of its Quantum software network management tools that can manage the hodgepodge of small cells and integrate them with the macro network core.

Review: Facebook Home
It’s not simply the case that Zuckerberg is sneaky in his promotion of sharing and creepy in his ambivalence about privacy. Rather, he is a true believer. Privacy lowers the value of the social graph. If one sincerely believes in the merits of the graph, then one should be suspicious of privacy, because privacy is selfish.
Roman Seawater Concrete Holds the Secret to Cutting Carbon Emissions
The Romans made concrete by mixing lime and volcanic rock. For underwater structures, lime and volcanic ash were mixed to form mortar, and this mortar and volcanic tuff were packed into wooden forms. The seawater instantly triggered a hot chemical reaction. The lime was hydrated – incorporating water molecules into its structure – and reacted with the ash to cement the whole mixture together.

This seems like an amazing discovery.
Their analyses showed that the Roman recipe needed less than 10 percent lime by weight, made at two-thirds or less the temperature required by Portland cement. Lime reacting with aluminum-rich pozzolan ash and seawater formed highly stable C‑A-S-H and Al-tobermorite, insuring strength and longevity. Both the materials and the way the Romans used them hold lessons for the future.
Attacks on Package Managers
To provide an example of the sorts of attacks an attacker can launch on package managers, this page describes an example attack called a replay attack. Other attacks are described on a separate page.
via Attacks on Package Managers.
Here’s a piece of advice I always adhere to for any kind of upgrade.
Manually update your systems (and local mirror caches). Know when package updates become available and what the versions should be. Manually verify and install the updated packages (or add them to your local mirror cache that your systems update from) rather than relying on automated updates. We have observed mirrors many months out of date for some distributions, so you should check periodically that your mirror is being updated.
