Concorde's last flight: Is this the greatest aviation photograph of all time?

Image
On November 26, 2003, supersonic airplane Concorde made its last flight, returning to the airfield near Bristol, in southwest England, where it's remained since.  As this marvel of modern engineering soared over the Clifton Suspension Bridge in Bristol, a landmark of Victorian engineering based on a design by Isambard Kingdom Brunel, it created a poignant moment witnessed by cheering crowds.  High in the sky, dangling out of a helicopter and buffeted by icy winds, photographer Lewis Whyld managed to capture it on camera -- an image that has become the defining shot of the golden age of faster-than-the-speed-of-sound travel.  Whyld, who now works as an aerial cameraman for CNN, reveals how he took one of the coolest airplane photos ever taken.

Monitoring Airport Security Operations with Canvas & Elasticsearch

Image
At Crimson Macaw, we recently took on an interesting project with Manchester Airport Group (MAG). We were to create and implement real-time dashboards for Airport Security Operations at Stansted Airport.  This would give the control room and security staff a better view of the passenger flow and security performance, allowing them to quickly make decisions based on real-time data. Data needed to be ingested from a number of on-premises systems and external data sources and then visualised on a number of large screens.

How to Spend The First Hour of Your Work Day on High-Value Tasks

Image
Don’t begin the activities of your day until you know exactly what you plan to accomplish. Don’t start your day until you have it planned. — Jim Rohn  Every morning, get one most important thing done immediately.  There is nothing more satisfying than feeling like you’re already in the flow.  And the easiest way to trigger this feeling is to work on your most important task in the first hour.

The Greatest Sales Deck I’ve Ever Seen - It’s Zuora’s, and it’s brilliant. Here’s why.

Image
The sales deck I showed Tim came from Zuora, the IPO-bound Silicon Valley company that sells a SaaS platform for subscription billing. If you pay for anything on a recurring basis (e.g. enterprise software), there’s a good chance that Zuora facilitates those transactions.

The changing data centre: Impact of networking costs

Image
Mattias Fridström, chief evangelist for Telia Carrier, says lower networking hardware costs are forcing data centers and metro networks to fundamentally change how they conduct their business: “Any location with fiber can now become a data center, opening up new opportunities for designing, managing, and operating cloud and on-demand computing resources.”  In the past the networking hardware costs were extremely prohibitive, and so connecting different data centers to each was often an expensive exercise. Organizations such as Google, Facebook, Amazon and Intel have been at the forefront of the software designed revolution in computing, and they are now moving into the networking arena with SDN and SD-WAN. This is displacing the traditional costly propriety silicon purveyors on network equipment. With lower costs and higher speed connections, the dynamics are changing. In turn this is transforming the costs associated with data centers, public, hybrid and private clouds –…

MPLS vs. Ethernet: Which WAN connectivity option is best?

Four Myths of SDWAN

Image
SD-WAN is the topic of everyone’s telecommunications conversations today. Unfortunately, the interest is being fueled by some misconceptions about what benefits SD-WAN provides. When discussing solutions with your customer, having your facts straight is an important step toward making the right recommendation and, ultimately, making sure your customers are happy.



The SD-WAN Vendor List

Image
SD-WAN services and equipment  come in all shapes and forms today. As we discussed in our recent blog, you can buy SD-WAN equipment (and software) and do it yourself (DIY), subscribe to an over-the-top (OTT) SD-WAN service, or have your SD-WAN bundled with a carrier network, such as MPLS or Direct Internet Access (DIA).
To help kick off your research, we’re creating this live page of SD-WAN providers.



Modsecurity - open source web application firewall

Image
ModSecurity is an open source, cross-platform web application firewall (WAF) module. Known as the "Swiss Army Knife" of WAFs, it enables web application defenders to gain visibility into HTTP(S) traffic and provides a power rules language and API to implement advanced protections.

The Security of SD-WAN

Image
Perhaps we exaggerate, but IT professionals, especially those involved in telecommunications, should always beware of anything that's connected to the Internet, as well as services provided across the Internet. That includes websites, email, cloud-based applications, and of course, WANs.  The bad news is that the wild, unfettered Internet can indeed be a dangerous place; it's a good thing we have firewalls, universal threat defense, intrusion prevention systems, heavily encrypted VPNs and endpoint security to protect us. The good news is that SD-WAN, one of the fastest-growing technologies for connecting branch offices, data centers, cloud services and remote locations, are perfectly safe.

Four Reasons Why SD-WAN Makes Sense

Image
Virtualization has revolutionized the data center, and now the next step is revolutionizing the network. Central to the networking revolution is software-defined networking (SDN), which allows network administrators to virtualize their networking hardware and bring added agility and cost savings.  Although all networking of all types can benefit from SDN, one area ripe for adoption is the wide area network (WAN). SD-Wan, as software-defined WAN is called, can enable businesses to harness virtualization and reap the benefits not only of improved agility and cost, but also other benefits. Companies such as CloudGenix are pushing forward with SD-WAN technology and giving businesses an easy adoption path.
Here are four reasons why SD-WAN makes sense.

Technical Assitance Guidelines on the employment of people with disablities

Image
Inequality and discrimination in the workplace are some of the key elements of the legacy of Apartheid in South Africa. Persons with Disabilities have been excluded from the mainstream of society and experience difficulty in accessing fundamental rights. Legislation has in the past also contributed to the social and economic exclusion of Persons with Disabilities. Under our new democracy, the rights of the Persons with Disabilities are now protected in the Constitution. Using the Constitution as a foundation, the South African government introduced the Employment Equity Act, 1998 (the Act) to redress inequalities and discrimination in the workplace. To further ensure that the rights of Persons with Disabilities are protected in the workplace, my Department, on the advice of the Commission for Employment Equity published the Code of Good Practice on the Employment of Persons with Disabilities (Code) in 2015. The ai…

Presenting To The D-Suite

Image
Do you present to an audience? Odds are good that most of us have had to do it more than once in our life or career. Some of us do it rather often. And there’s no shortage of advice out there about how to present to an audience. A lot of it is aimed at people that are trying to speak to a general audience. Still more of it is designed as a primer on how to speak to executives, often from a sales pitch perspective. But, how do you present to the people that get stuff done? Instead of honing your skills for the C-Suite, let’s look at what it takes to present to the D-Suite.

Anatomy of a crisis: why SA is on the brink of rolling blackouts

Image
Eskom has shut down 11 power station units due for major maintenance because it lacks the funds to fix them. This comes as the embattled power utility struggles to find coal to feed its coal-fired power stations — the bulk of its fleet. Moneyweb earlier reported that 11 of Eskom’s 15 coal-fired power stations have less than the required 20 days’ coal stock — and of those, five have less than 10 days’ stock.
