Code Generation: The Inner Sanctum of Database Performance

This is guest post by Drew Paroski, architect and engineering manager at MemSQL. Previously he worked at Facebook and developed HHVM, the popular real-time PHP compiler used across the company’s web scale application.

Achieving maximum software efficiency through native code generation can bring superior scaling and performance to any database. And making code generation a first-class citizen of the database, from the beginning, enables a rich set of speed improvements that provide benefits throughout the software architecture and end-user experience.

If you decide to build a code generation system you need to clearly understand the costs and benefits, which we detail in this article. If you are willing to go all the way in the name of performance, we also detail an approach to save you time leveraging existing compiler tools and frameworks such as LLVM in a proven and robust way.

The Vast Potential For VMware’s OpenStack Cloud

While hyperscalers and HPC centers like the bleeding edge – their very existence commands that they be on it – enterprises are a more conservative lot. No IT supplier ever went broke counting on enterprises to be risk adverse, but plenty of companies have gone the way of all flesh by not innovating enough and not seeing market inflections when they exist.

VMware, the virtualization division of the new Dell Technologies empire that formally comes into being this week, does not want to miss such changes and very much wants to continue to extract revenues and profits from its impressively …

Consumers have no right to buy a PC without an OS, European court rules

Bare metal buyers beware: PC makers have no obligation to offer you a machine without an OS, the European Union's highest court has ruled.The case dates back to PC prehistory, a time when Vaio was still a Sony brand and Vista was the latest version of Windows.It all began on Dec. 27, 2008, when Frenchman Vincent Deroo-Blanquart bought a Sony Vaio laptop with Windows Vista Home Premium and various software applications installed. Deroo-Blanquart refused to accept the Vista end-user license agreement (EULA) when he first turned the PC on, and on Dec. 30, asked Sony to refund the part of the computer's €549 (then US$740) purchase price corresponding to the cost of the software.To read this article in full or to leave a comment, please click here

Worth Reading: What Facebook learns by shutting down entire facilities

As we have reported before, Facebook has one of the boldest approaches to testing its infrastructure resiliency.

During his keynote this morning at the Facebook @Scale conference in San Jose, California, Jay Parikh, the company’s head of engineering and infrastructure, shared some of the big lessons his team has learned so far from these fire drills. —Data Center Knowledge

‘Stupid simple’ attack can steal credentials from locked Windows and Mac computers

Hats off to security researcher Rob Fuller, aka mubix, for spending part of his Labor Day weekend figuring out how to use a spoofed USB Ethernet adapter to steal credentials from logged in but locked Windows and Mac computers. It works!!! Muhahahahah I can steal credentials from a locked computer. Muahahahhahahahah pic.twitter.com/9l3d0tvs8i— Rob Fuller (@mubix) September 4, 2016 Fuller did not use a zero-day; although the attack is “stupid simple” and “should not work,” it does work because most computers automatically install Play-and-Play USB devices. “Even if a system is locked out, the device still gets installed.” There may be restrictions on what devices can be installed when the box is a locked state, but he said, “Ethernet/LAN is definitely on the white list.”To read this article in full or to leave a comment, please click here

IDG Contributor Network: Cambium Networks helps provide the network for the IoT

We here a lot about the Internet of Things (IoT) these days. Call it the IoT, the industrial internet, the internet of customers or some other variation on a theme, but it means essentially the same thing—devices and sensors in a dizzying variety of different locations being connected and able to exchange data. But many of the use cases we see for IoT are pretty lightweight in terms of their operating requirements. While a connected toaster, refrigerator or toothbrush might make for a great concepts video, it’s not exactly difficult from a connectivity perspective—just leverage the existing wireless network that already exist in a home and from there jump onto the public internet.To read this article in full or to leave a comment, please click here
