Windows-Linux File Synchronisation

My development environment usually consists of a host machine running Windows and a development Linux “headless” virtual machine. I create and edit files in a Notepad++ text editor and then transfer them over to the Linux VM. Until recently I’ve been using a hypervisor-enabled “shared” folder. However, Windows file system emulators in Linux do not support symbolic links and therefore breaks a lot of applications that rely on them. This prompted me to start looking for a new way to sync my files. That’s how I came across this new amazing file syncing app called Syncthing. Why is it amazing?

  • It uses peer-to-peer architecture. User traffic is not uploaded to a centralised server and is transferred directly between peers.
  • It is open-source. It doesn’t use any proprietary syncing protocols like BTSync.
  • As the result of open-source nature it has big community support with clients, wrappers and extension available for any major platform.
  • It is secure. All transfers are TLS-encrypted.
  • It’s simple to use. Windows version installs like any other Windows app, Linux version, like any other Linux app, will take a little tinkering.
  • It’s written in Golang, an extremely popular language amongst professional programmers and surely these guys can’t be Continue reading

Happy Father’s Day, from the Father of Hyperconvergence

One thing that's cool about my job as a tech business publication editor is getting to meet industry pioneers, as I did by phone this past week with Mohit Aron, widely considered to be the Father of Hyperconvergence as a co-founder of Nutanix and now the founder and CEO of startup Cohesity (you can read my Q&A with Aron here). Over the years I've met a bunch of industry Fathers, including Bob Metcalfe of Ethernet fame and Vint Cerf of Internet fame, as well as industry Mothers, like Radia Perlman of Spanning Tree fame.To read this article in full or to leave a comment, please click here

Message Queues: RabbitMQ in Go and Python

I’ve been playing around with various message queue implementations for a few projects, and wanted to write a quick post on some basics. Message Queues Before we get into the detail of RabbitMQ, it’s worth briefly defining exactly what a message queue is, of which RabbitMQ is just one implementation. You may have heard message queues described as a “Publish/Subscribe” system, or “Pub/Sub” for short. This is a style of communication between software elements, where some components publish messages onto a queue, and others subscribe to that queue and listen for messages published on to it.

What the FCC’s new robocall rules mean for your company’s marketing efforts

Marketers now face tougher restrictions on their use of “robocalls” and other automated telemarketing techniques thanks to a new set of declaratory rulings issued by the FCC on Thursday.Although the Telephone Consumer Protection Act of 1991 requires prior consent for autodialed, prerecorded or artificial voice calls to wireless and residential wireline numbers, marketers have still been able to exploit numerous loopholes to make questionable calls anyway.Now, in response to thousands of consumer complaints and nearly two dozen petitions, the FCC has affirmed consumers’ rights to control the calls they receive and made it clear that telephone companies can use robocall-blocking technology to help them.To read this article in full or to leave a comment, please click here

Hackers had access to US security clearance data for a year

Hackers who breached a database containing highly personal information on government employees with security clearances had access to the system for about a year before being discovered, The Washington Post reported on Friday.The breach at the U.S. Office of Personnel Management dates back to June or July last year and was only discovered earlier this month.The database in question contains applications for security clearances, which ask for information on all aspects of a person’s life including social security numbers, passport numbers, names of former neighbors, and information on family members. It also asks about, over the past seven years, any contact with foreign nationals and problems with drug or alcohol abuse, debts or bankruptcy, imprisonment and run-ins with law enforcement.To read this article in full or to leave a comment, please click here

Twitter tests a new way to sell goods

Twitter has long positioned its site as a way to see what’s happening in the world. Now, it wants to tap into our desires as consumers.The company is testing a new way to highlight products and places on its site, bringing relevant tweets to the fore while also providing a way to purchase items. It’s a considerable expansion beyond the company’s previous forays into e-commerce.In an example, it showed a page it built for the book “The Martian,” complete with related images, tweets, and a button that says Buy on Twitter. The new pages will be promoted through people’s Twitter feeds.As well as Twitter building these pages, celebrities and brands will be able to build them too. It offered examples of pages built by Demi Lovato, Reese Witherspoon, Nike and Target, the last of which is filled with tweets promoting summer clothing, for example.To read this article in full or to leave a comment, please click here

eBay sells stake in Craigslist, which responds with Shakespeare quote

EBay has sold its 28.4 percent ownership stake in Craigslist as part of an agreement between the companies announced Friday .The financial terms of the deal were not disclosed, but eBay said the companies have also agreed to end the outstanding litigation between them. The online auction house paid $32 million in 2004 for the stake in Craigslist, which turned the classified ad market on its head.Since then, the relationship between the two firms could best be described as contentious. In 2008, eBay sued Craigslist alleging it had diluted eBay’s stake in the business and taken eBay’s board seat away. Craigslist fired back that eBay had used its position on the board to gain an unfair competitive advantage.To read this article in full or to leave a comment, please click here
