Surface tablets

“On the hardware front, what does it say about the tablets Microsoft is seeing from its OEM partners…? Either they are not happy with the devices out there, or they are not satisfied with only taking a licence fee from selling Windows-based tablets.”Jan Dawson

Today’s WhatIs.com Word of the Day is Surface, Microsoft’s new line of tablets which will go on sale later this year.

Surface tablets are expected to be priced comparably to Apple and Android products, with the Windows RT version selling for about the same price as its chief competitor, the iPad, and the Windows 8 Pro version selling for the same price as the MacBook Air laptop.

VMware Horizon Application Manager

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“The app manager doesn’t just keep track of access to applications, but also licensing, and it knows how to harvest back a license if you are not using it.” Timothy Prickett Morgan

Today’s WhatIs.com Word of the Day is VMware Horizon App Manager. In my humble opinion, app managers are the firewalls of the future.  Firewalls with application portfolio management benefits.

Cloud database

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“The wrong cloud database strategy can create application performance problems significant enough to discredit a cloud service, forcing the provider to incur additional costs to establish credibility with users.” — Tom Nolle

Today’s WhatIs.com Word of the Day is cloud database. A cloud database is a database that has been optimized or built for a virtualized computing environment.

Open APIs

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“One of the cardinal rules of open source is reciprocity: you can use my open-source code under the same terms that it was given to me. But as open source shifts to open APIs, “open” is increasingly a one-way street.” Matt Asay

Today’s WhatIs.com Word of the Day is open API.  It’s what makes all your iPhone apps possible.  Developers have a love/hate relationship with them because they make mashups possible (that’s the love part) but the API publisher has all the power in the relationship (that’s the hate part).

Dirty electricity and electrical pollution

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“It’s like Tesla versus Edison all over again. Alternating current (AC) is king today, but when it comes to finding ways to improve data center energy efficiency, some industry experts say direct current (DC) deserves a second look.”Alex Barrett

Today’s WhatIs.com Word of the Day is dirty electricity — also known as electrical pollution.

From Power-saving technologies in the data center

Electricity comes from the utility in alternating current (AC). AC is the form in which power is more easily distributed. AC is converted to DC at the power distribution unit, then converted to AC again to push out to the servers, and is converted one more time to DC at each individual server.

In a DC power distribution system, there is only one conversion from the main building AC to DC at common power supply for multiple pieces of equipment. The DC power is fed directly to the servers and switches, and also keeps the batteries charged. This has been the approach in the telco industry for decades on high-end PBX equipment.

DC-powered servers don’t have power supplies built in. The power supply is in the infrastructure. Taking the power supplies out of the equipment itself and putting it in the rack reduces space and takes away the need for an extra conversion.

NoOps – the end of the operations team as we know it today

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“The developers used to spend hours a week in meetings with Ops discussing what they needed, figuring out capacity forecasts and writing tickets to request changes for the datacenter. Now they spend seconds doing it themselves in the cloud.” — Adrian Cockcroft

Today’s WhatIs.com Word of the Day is NoOps.  NoOps is one of those buzzwords that gets people’s blood boiling.  It implies the end of the operations team as we know it today.  But be careful, because the key takeaway in that sentence is “as we know it today.”

IT is becoming a utility that we purchase from a third-party provider. And just as you won’t find a generator for electricity and a team to support it on your next visit to Company XYZ, you’re not going to find a fully-staffed operations team there ten years from now.

Event-driven architectures and service-oriented architectures are complements

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“In the real world, a service-oriented archtecture (SOA) and an event-driven architecture (EDA) are complements. An EDA allows special handling of application communications that are of vital importance to the enterprise. An SOA extends flexible application communications across the Web.”Wayne Kernochan

Today’s WhatIs.com Word of the Day is event-driven application.

Gamification and app/dev

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“Help desks are ripe for gamification. “It’s a difficult job dealing with customer issues so if we can make this more fun that would be great.” — Kris Duggan

Today’s WhatIs.com Word of the Day is gamification, the application of game theory concepts and techniques to non-game activities.

Quad gate

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“The NAND gate has the property of functional completeness. That is, any other logic function (AND, OR, etc.) can be implemented using only NAND gates. An entire processor can be created using NAND gates alone.’
” –
Steven Colyer

Today’s WhatIs.com Word of the Day is quad gate. A quad gate an IC (integrated circuit or chip) containing four logic gates. The quad NAND gate is of particular interest, because any of the basic logic functions can be derived by connecting multiple NAND gates together. This feature makes the quad NAND gate useful as a “universal digital substitute,” and also can help students learn how digital logic circuits work.

Minify those JavaScript and CSS files!

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“One of the best practices to speed up a web site or web application is to minify JavaScript and CSS files; which as a secondary effect, not only reduces the size of those files but also makes them harder to read (something helpful to prevent the stealing of your ideas and efforts).” — Roderigo Liberoff  

Today’s WhatIs.com Word of the Day is minification.  It’s the the removal of unnecessary characters from source code. The term minification is often associated with interpreted scripted languages that are deployed and transmitted over the Internet.
