Ticked at President Trump, Shadow Brokers dump password for NSA hacking tools

Ticked at President Trump, the Shadow Brokers hacking group released the password for the NSA hacking tools they previously tried to sell.In an open letter to President Donald Trump, the group asked, “Respectfully, what the f**k are you doing?” In broken English, they accused the president of “abandoning ‘your base,’ ‘the movement,’ and the peoples who getting you elected.”After a “quick review” of the tools unlocked with the password, Edward Snowden noted that “it’s nowhere near the full library, but there’s still so much here that NSA should be able to instantly identify where this set came from and how they lost it. If they can’t, it's a scandal.”To read this article in full or to leave a comment, please click here

Curaçao and Djibouti – two new Cloudflare datacenters located where undersea cables meet

Cloudflare has just turned up two new datacenters (numbers 108 and 109). Both are around halfway between the Tropic of Cancer and the Equator. They are located continents-apart, yet share something very-much in common as both of these new data centers are deployed and associated with where undersea cables reach land. Undersea cables have been and still are a growing part of the interconnected world that the Internet represents.

Curaçao, part of the Netherland Antilles in the Caribbean

Curaçao is located in the Southern Caribbean Sea (just north of Venezuela) and has a strong Dutch heritage. Along with Aruba and Bonaire, Curaçao is part of the Lesser Antilles (they are called the ABC islands).

More importantly, Willemstad - the capital of Curaçao is where the Amsterdam Internet Exchange operates AMS-IX Caribbean. Why AMS-IX? Because of that Dutch relationship!

It’s AMS-IX’s goal (along with its local partners) to promote Curaçao as an interconnection location for the Caribbean. Cloudflare is there with all its services ready for that day!

Djibouti on the horn of Africa

Djibouti is a country of around 850,000 people with ~60% of the population living in the nation's capital, also Continue reading

How to improve Dynamic Lock in Windows 10 Creators Update

When Microsoft released Build 15031 of the Windows 10 Insider Preview on February 8, 2017, it added a new OS feature for Bluetooth-equipped devices. It's called Dynamic Lock, and lets you control access to your PCs based on how close they — and your Bluetooth-paired phones — are to them. That is, if the phone you've paired with your PC (it works for laptops, notebooks, tablets and desktops) is not found within radio range of your PC, Windows 10 turns off the screen and locks the PC after 30 seconds have elapsed. Thus, Dynamic Lock makes a dandy new security feature in Creators Update, one that most business users (or their IT departments) will find worth turning on and using.To read this article in full or to leave a comment, please click here

Windows Embedded’s future looks rocky

Ah, Windows Embedded. The Microsoft operating system that millions of devices and machines are running, typically with a custom application or skin running on top of it so that users don't automatically notice the OS. The operating system that underpins hundreds of thousands of medical devices, automatic teller machines, kiosks at airports and other crowded public places, industrial machinery and control planes, set top boxes, game consoles.Windows Embedded is a relatively unheralded version of Windows whose existence might surprise you. But it seems like Windows Embedded's existence might also surprise a lot of folks up in Redmond. Here, at the Microsoft campus, despite all of the hullabaloo about Windows 10 and device updates -- and the new Creators Update and Redstone versions that will be coming down the pike at an almost breakneck speed -- Windows Embedded suffers from an opposite problem. It appears unfortunately stuck in a place where no future has clearly been laid out for it.To read this article in full or to leave a comment, please click here

Predictive analytics can stop ransomware dead in its tracks

This past February marks the two-year anniversary when Livingston County, Michigan, was hit by ransomware. The wealthiest county in the state had three years’ worth of tax information possibly at the mercy of cybercriminals.As a local government, county CIO Rich C. Malewicz said they have been a target of ransomware, but in this instance they had backups at the ready. He said the most memorable ransomware attack was a result of a watering hole campaign using malvertizing to infect users visiting a local news website. “This attack was very clever in that all you had to do to get infected was visit the website, you didn't even have to click on the page. Once the user went to the local news website, they were immediately redirected to a site hosting exploit code and the infamous page appeared demanding a ransom with instructions,” he said.To read this article in full or to leave a comment, please click here

Singularity Containers for HPC, Reproducibility, and Mobility

Containers are an extremely mobile, safe and reproducible computing infrastructure that is now ready for production HPC computing. In particular, the freely available Singularity container framework has been designed specifically for HPC computing. The barrier to entry is low and the software is free.

At the recent Intel HPC Developer Conference, Gregory Kurtzer (Singularity project lead and LBNL staff member) and Krishna Muriki (Computer Systems Engineer at LBNL) provided a beginning and advanced tutorial on Singularity. One of Kurtzer’s key takeaways: “setting up workflows in under a day is commonplace with Singularity”.

How to deal with the bot crisis on Twitter

You may have run into these bots a few times. What looks like an actual human being could have been a bot sending you Twitter spam...or even worse.During the last election cycle and over the past few months in particular, it’s now widely known that Twitter bots -- many with zero followers -- promoted fake news stories. Often, the goal was to stir up dissension among voters, influence political viewpoints, and (more importantly) generate revenue when people viewed banner ads. Some would argue these bots helped elect President Trump or at least influenced people on social media to vote one way or another.To read this article in full or to leave a comment, please click here(Insider Story)

Managing the Cloud Network: CPM or APM?

We all know the future of enterprises is in flux with the consolidation or demise of Avaya/Nortel, Brocade/Foundry, Force 10, H3C and BNT assets. This speaks to the major trend of enterprise applications migrating to the cloud, any cloud be it public, private or hybrid. As this rapid transition prevails with efficiencies and scale, traditional applications and tools cannot meet the needs of exponential cloud growth.
