With the tablets’ larger screen size, pages for individual listings also feature photos and links to similar listings, resembling the look of a print magazine’s sidebar article. Rotate the tablet from a horizontal to vertical position, and the app’s interface will reorient itself.To read this article in full or to leave a comment, please click here

Social media helps curb Nigerian election deathtoll, paving future path

The dozens of deaths that marred the recent Nigerian elections would be considered shocking by the standards of most developed nations. Compared to past elections, however, the violence this time around was limited, and many observers say social media and technology such as biometric card readers played a big role in minimizing conflict.Online services are credited with keeping people informed during the runup to the elections, promoting the feeling they could communicate and express their views without resorting to violence, and other technology helped to ensure cheating would be kept to a minimum. Nigeria’s experience suggests that tech can play a role in reducing election-related violence in other countries.To read this article in full or to leave a comment, please click here

IDG Contributor Network: New algorithms could keep drones from crashing into people

Major delivery firms are experimenting with drones for deliveries. If you've started to experiment with drone flying for fun, you'll know that it isn't easy. There's a steep learning curve, and they crash quite a lot, I've found.However, it doesn't have to be like that. Collision avoidance is technically feasible. The drone senses objects and diverts.One of the issues with that, though, has been that developers only have a certain amount of time and money to develop new features. Those features have, thus far, been the tempting, seductive ones, like "follow-me" where the hobbyist drone follows the pilot like a dog on a leash. It's the latest thing.To read this article in full or to leave a comment, please click here

Google Fi app surfaces on Play Store, though most can’t use it yet

The Google Fi app showed up for the first time Wednesday on the Play Store: The catch is that you'll need a Nexus 6 phablet and an invitation to the new wireless service in order to make any use of it. Google's Project Fi, unveiled last week to mixed reviews, offers a potentially lower cost wireless service whose magic includes a SIM card that enables your Android device to bounce between Sprint and T-Mobile LTE networks as well as WiFi hotspots. Initially, the mobile virtual network operator (MVNO) service will only be available on the Nexus 6.To read this article in full or to leave a comment, please click here

PC prices to go up later this year, Gartner warns

PC prices have enjoyed record lows for many years now, but buyers might have to shell out a few more bucks for their desired laptop or desktop later this year. Research firm Gartner is sounding the alarm that PC prices might go up later this year due to recent currency fluctuations. The effect may especially be felt in Europe and Japan, where local currencies are weakening against the U.S. dollar. The alternative to rising prices is fewer features. PC makers might opt for less memory, a cheaper webcam or a lower-capacity hard drive to avoid higher prices. PC makers do something similar every holiday shopping season when they sell computers at rock-bottom prices.To read this article in full or to leave a comment, please click here

Uber shifts strategy, requiring taxi licenses for Dutch UberPop drivers

Uber will require drivers of its Dutch UberPop ride-hailing service to have a taxi license. That will not, however, be enough to mitigate its legal troubles in the country.UberPop connects passengers with drivers who use their own cars and typically don’t have a taxi license, allowing them to offer rides for a much lower fare then regular taxis.A Dutch court last year declared the service illegal, banning it because it unfairly competes with strictly regulated taxi services. Even though fines totaled €100,000, several UberPop drivers landed in court and Dutch authorities raided company offices, Uber kept on flouting the ban, operating UberPop with unlicensed drivers.To read this article in full or to leave a comment, please click here

Introducing Multi-User Organizations: Share An Account Without Sharing A Login

An enterprise needs security and controls around access.

Your web developer needs to update your website’s logo and make sure it’s live immediately, but doesn’t need access to your SSL keys. Your sysadmin manages your DNS, but doesn’t need to see your visitor traffic. Your marketing team needs to see traffic, but shouldn’t have access to your WAF.

Today CloudFlare is introducing new Multi-User functionality so that many members of a team can work together to manage one CloudFlare account, each with different levels of access.

The Super Admin, and Role-Based Permissions

CloudFlare Multi-User accounts are hierarchical, with the root privileges given to the account’s Super Administrator. The Super Administrator can add or delete users in the organization, change the permissions given to each user, and see and edit all CloudFlare settings. If there is more than one Super Administrator, the Super Administrators can remove each other, which is good practice when an employee leaves the company or switches jobs.

When a user joins a multi-user organization on CloudFlare, they can only see and access the settings that a Super Admin has delegated to them. For example, a user added to the organization as a DNS Administrator would only be Continue reading

Introduction to Storage Networking and Design

Introduction

Storage and storage protocols are not generally well known by network engineers. Networking and srorage have traditionally been two silos, Modern networks and data centers are looking to consolidate these two nettworks into one and to run them on a common transport such as Ethernet,

Hard Disks and Types of Storage

Hard disks can use different type of connectors and protocols.

Advanced Technology Attachment (ATA)
Serial ATA (SATA)
Fibre Channel (FC)
Small Computer System Interface (SCSI)
Serial Attached SCSI (SAS)

ATA and SATA and SCSI are older standards, newer disks will typically use SATA or SAS where SATA is more geared towards the enterprise market. FC is used to attach to Storage Area Network (SAN)

Storage can either be file-level storage or block-level storage. File-level storage provides access to a file system through protocols such as Network File System (NFS) or Common Internet File System (CIFS). Block-level storage can be seen as raw storage that does not come with a file system. Block-level storage presents Logical Unit Number (LUN) to servers and the server may then format that raw storage with a file system. VmWare uses VmWare File System (VMFS) to format raw devices.

DAS, NAS and SAN

Storage can Continue reading

Facebook, under siege, slams European privacy regulators

Facebook has warned that overlapping national probes into its privacy policy could severely endanger the European Union’s economy if such a fragmented strategy is continued and applied to other businesses.The social networking company also warned that the high cost of compliance with multiple national laws, rather than with an overarching EU regime, could cause it to introduce new features more slowly or not at all.Data protection authorities from Belgium, the Netherlands and Germany in February formed a task force to deal with Facebook’s new privacy policy, introduced late January. They suspect that the new policy violates EU privacy laws. French, Spanish and Italian authorities later joined the group.To read this article in full or to leave a comment, please click here
