Fixing My Twitter

It’s no surprise that Twitter’s developers are messing around with the platform. Again. This time, it’s the implementation of changes announced back in May. Twitter is finally cutting off access to their API that third party clients have been using for the past few years. They’re forcing these clients to use their new API structure for things like notifications and removing support for streaming. This new API structure also has a hefty price tag. For 250 users it’s almost $3,000/month.

You can imagine the feedback that Twitter has gotten. Users of popular programs like Tweetbot and Twitterific were forced to degrade client functionality thanks to the implementation of these changes. Twitter power users have been voicing their opinions with the hashtag #BreakingMyTwitter. I’m among the people that are frustrated that Twitter is chasing the dollar instead of the users.

Breaking The Bank

Twitter is beholden to a harsh mistress. Wall Street doesn’t care about user interface or API accessibility. They care about money. They care are results and profit. And if you aren’t turning a profit you’re a loser that people will abandon. So Twitter has to make money somehow. And how is Twitter supposed to make money in today’s Continue reading

The Internet Society and Global Scribes Work Together to Amplify Young Voices

On International Youth Day, the Internet Society and Global Scribes partnered to connect youth around the world to let their voices be heard, allowing them to become empowered and engaged global citizens, striving toward a more united and sustainable digital future.

As local and international actors innovate to solve the most pressing issues that we face in the world today, young people are often left out of the equation with little or no participation in important discussions and decision-making processes.

Youth across the world are often overlooked as a potential resource to solving global challenges, such as climate change, migration, health, and unemployment, despite being directly impacted by these issues and having opinions on how to solve them.

This also happens in the Internet ecosystem, where young people often do not have a place at the table when it comes to decisions that shape the Internet’s future.

While youth are recognized as “the future generation” and perceived as key to a more sustainable tomorrow, they are seldom given adequate platforms to let their voices be heard or allow them to contribute to their societies in a meaningful way, in their own right as youth.

Young people are often deprived of the opportunity to serve as catalysts for a more united and sustainable world Continue reading

How IT Pros Can Bridge the IT-Business Gap

Dell EMC rolls out future-proofed high-performance servers

Dell EMC has launched a new line of high-performance servers called the PowerEdge MX that the company said is designed to support a wide variety of traditional and emerging data center workloads, such as artificial intelligence.PowerEdge MX offers the first modular infrastructure architecture designed to easily adapt to future technologies and offers what Dell calls “server disaggregation.” What that means is customers can tailor configurations to their needs from shared pools of disaggregated resources, which can be changed as needed. If a company needs more or less compute, it can reprovision that resource on the fly to avoid overprovisioning and wasted assets.To read this article in full, please click here

AfPIF 2018 Day Three: Cloud Infrastructure, Local Content, and More

The growth of cloud infrastructure in Africa has been credited with the growth of local content in many regions, and it holds the key for Africa’s ability to attract content carriers and distribution networks.

The first panel of day three at the Africa Peering and Interconnection Forum (AfPIF) was dedicated to discussing the current scenario of cloud infrastructure and what it will take to grow the sector further, get the market interested, and eventually grow the level of content hosted locally.

South Africa has the most extensive cloud market, compared to other African countries, and it took concerted efforts from the different players, under the ISP Association, for the market to be deregulated and the laws to be put in place. The laws can take time, but industry players agree the laws are vital to investments in the market.

Although the industry may be small in Africa, cybersecurity is key, as businesses are susceptible to cybercrime, just like other global operators. That means the enactment of cyber security laws in the different countries, and continued training and awareness by industry players.

Power and cooling is another vital part, with many countries enjoying monopoly of power distribution. Liquid Telecom said Continue reading

To Go or not to Go

Back in yesteryear, I used to be a C developer and enthusiast. Thanks to the infamous K&R C book, it made perfect sense when I needed a language that provided syntax what I thought of at the time as one level higher than assembly.
Roll the clock forwards a decade and Go has become my ‘go to’ (multi-pun intended) language. It’s powerful from its simplicity, easy to debug and super easy to observe when things aren’t going as you planned. The concurrency capabilities seem to make perfect sense and development cycles are short thanks to the powerful “batteries included” tool-chain. Building binaries couldn’t be easier and building containers for the likes of Docker is a piece of cake. Thanks also to the language’s popularity, tools like Travis-CI are easy to work with. Powerful enough to do almost anything, easy enough to learn in days and offers Continue reading

NSX Cloud at VMworld US 2018

We have done a series of blogs on NSX Cloud in the last couple of weeks and the response has been great! We have customers who have purchased licenses already and are on-route to deployment, customers with whom we have completed POCs successfully, and a pipeline that looks promising. Meanwhile, recognitions continue to flow from all sides, CRN rated NSX Cloud as one of the 10 best SDN solutions for 2018 and NSX Cloud was judged as Best of Show runners-up in the cloud computing category at Interop Tokyo. With all this excitement and VMworld around the corner, we couldn’t help but write again to provide more updates. So, here we go!

Before reading on, if you would like to quickly go over past blogs, here is your single pane of glass to past blogs *wink*. You can find a high-level overview of VMware’s vision for Virtual Cloud Network and how NSX Cloud fits into the broader vision over here. If you are like, duh! I know that, can you just give me an overview about NSX Cloud… we hear you and this is where you could go to refresh your memory on NSX Cloud.  If you are Continue reading

IDG Contributor Network: Does your network have a trade imbalance?

Network traffic, by nature, is often unbalanced. For example, a client that requests a video on demand may receive ten times more bandwidth than it sends for that service. Likewise, most web applications are very one-sided, with the bulk of the traffic being from server to client. The opposite is true for many backup applications, where the bulk of the traffic originates at the client and terminates at the server.The United States is like your network – suffering from a trade imbalance. For every packet we ship to a foreign network, we are receiving four or five in return. Just as there are barriers to trade, we apply barriers to our inbound traffic. The barrier for most of us is the actual size of our Internet service interface. Packets queue up and drop at our carrier’s equipment prior to even being seen by our equipment. If you purchase a 50Meg download speed, any packets that arrive at a faster rate (even for a sub-second of time) will be dropped without prejudice. This is a barrier, restriction and tariff on your services that limit your business. The only solution – buy more bandwidth!To read this article in full, please Continue reading

At VMworld, Get An Inside Look at a Modern Bank. Learn How Wells Fargo and Other Top Brands Reduce Risk While Fostering Innovation.

This blog was co-authored by Jared Ruckle and Jonathan Morin.

VMworld is one of the seminal weeks in enterprise IT. You gather with your peers to learn and discuss the challenges of the day. And what are those challenges? Three stand out:

1. Rising consumer expectations. Your customers expect to interact with your brand on their terms. Self-service, mobility, and speed are table stakes. If you don’t deliver a responsive and engaging user experience, you’re irrelevant.
2. Increased competition from startups and incumbents. Your competitors aren’t only your peers in the FORTUNE 500. Startups all over the world are looking to take your market share.
3. Constantly evolving security threats from every direction. Speaking of table stakes: security. In an era where attacks can be launched for pennies – by anyone, from anywhere – you have take a different approach to InfoSec. You need to move faster. Speed and velocity aren’t just for development teams. It’s a crucial for a modern InfoSec mindset too.

Sound familiar? It should if you’re an IT leader. No matter where you are on your journey to get better at software, it’s always fun to learn from others. We want to highlight a few sessions Continue reading

ZTE Ban Tanks Q2 Optical Networking Market

The vendor would have been No. 3 behind Huawei and Ciena in worldwide optical networking hardware sales. Instead, Nokia snared that spot.

Australia Bans Carriers from Using Huawei and ZTE Equipment for 5G

The government argues that 5G blurs the line between the core network and the edge network, making security more challenging.

Research: Facebook’s Edge Fabric

The Internet has changed dramatically over the last ten years; more than 70% of the traffic over the Internet is now served by ten Autonomous Systems (AS’), causing the physical topology of the Internet to be reshaped into more of a hub-and-spoke design, rather than the more familiar scale-free design (I discussed this in a post over at CircleID in the recent past, and others have discussed this as well). While this reshaping might be seen as a success in delivering video content to most Internet users by shortening the delivery route between the server and the user, the authors of the paper in review today argue this is not enough.
