This review comes in two big meaty chunks to sink your teeth into. The first part is discussing the new Skylake-X processors, from silicon to design and covering some of the microarchitecture features, such as AVX-512-F support and cache structure. As mentioned, Skylake-X has some significantly different functionality to the Skylake-S core, which has an impact on how software should be written to take advantage of the new features.

The second part is our testing and results. We were lucky enough to source all three Skylake-X processors for this review, and have been running some regression testing of the older processors on our new 2017 testing suite. There have been some hiccups along the way though, and we'll point them out as we go.

An extra morsel to run after is our IPC testing. We spend some time to run tests on Skylake-S and Skylake-X to see which benchmarks benefit from the new microarchitecture design, and if it really does mean anything to consumers at this stage.

Microsoft researchers have created an artificial intelligence-based system that learned how to get the maximum score on the addictive 1980s video game Ms. Pac-Man, using a divide-and-conquer method that could have broad implications for teaching AI agents to do complex tasks that augment human capabilities.

When I started last year, ReactOS could read files from an NTFS volume, but had no write support whatsoever. After GSoC last year, the driver in my branch could overwrite existing files. I also fixed a few bugs in the driver's ability to read files, which have already been merged into the trunk. I also fixed ReactOS' implementation of LargeMCB's, which our NTFS driver has come to rely on, and which a few other filesystem drivers rely on.

My goals for this summer are simply file creation and deletion.

The current shell in ReactOS lets user manager running applications, start other applications and manage files but nothing more. This idea is about implementing 3 small shell extensions for showing the state of the battery of the machine, for ejecting usb devices and implementing the quick launch toolbar. These are important requirements and they are much needed while presenting ReactOS in real hardware. Not knowing the state of the battery or not being able to eject a usb flash drive is a serious usability problem. The shell extensions would be developed and tested to work on Windows.

It was almost four years ago I switched from webmail to a customized email configuration based on Notmuch and Emacs. Notmuch served as both as a native back-end that provided indexing and tagging, as well as a front-end, written in Emacs Lisp. It dramatically improved my email experience, and I wished I had done it earlier. I've really enjoyed having so much direct control over my email.

However, I'm always fiddling with things - fiddling feels a lot more productive than it actually is - and last month I re-invented my email situation, this time switching to a combination of Mutt, Vim, mu, and tmux. The entirety of my email interface now resides inside a terminal, and I’m enjoying it even more. I feel I've "leveled up" again in my email habits.

Over the last three weeks I've been working on a new randomization feature which will protect the kernel.

The situation today is that many people install a kernel binary from OpenBSD, and then run that same kernel binary for 6 months or more. We have substantial randomization for the memory allocations made by the kernel, and for userland also of course.

However that kernel is always in the same physical memory, at the same virtual address space (we call it KVA).

Improving this situation takes a few steps.

Google has hired a veteran chip architect away from Apple and is now looking to build its own chips for future versions of its flagship Pixel phone, Variety has learned from sources familiar with the hire. Manu Gulati, who had been spearheading Apple's own chip developments for close to eight years, joined Google in the last few weeks. He publicly announced the job change on his Linkedin profile Tuesday morning, stating that he now works as Google's Lead SoC Architect.

Microsoft first revealed its concerns over Chromebooks in an attack on Google’s laptops more than three years ago. While Chromebooks haven’t become best-sellers for consumers just yet, they have started to become popular with students in the US and slowly with some businesses. Microsoft is now revealing it's worried about this threat with two new videos on its Windows YouTube channel today.

The iPod phone was losing support. The executives debated which project to pursue, but Phil Schiller, Apple's head of marketing, had an answer: Neither. He wanted a keyboard with hard buttons. The BlackBerry was arguably the first hit smartphone. It had an email client and a tiny hard keyboard. After everyone else, including Fadell, started to agree that multitouch was the way forward, Schiller became the lone holdout.

He "just sat there with his sword out every time, going, 'No, we've got to have a hard keyboard. No. Hard keyboard.' And he wouldn't listen to reason as all of us were like, 'No, this works now, Phil.' And he'd say, 'You gotta have a hard keyboard!'" Fadell says.

Privately, Jobs had other reservations. One former Apple executive who had daily meetings with Jobs told me that the carrier issue wasn't his biggest hang-up. He was concerned with a lack of focus in the company, and he "wasn't convinced that smartphones were going to be for anyone but the 'pocket protector crowd,' as we used to call them."

At WWDC, Apple reported that they've paid out $70 billion to developers, with 30% of that ($21 billion!) in the last year. That's a huge spike, and surprising to me because it didn't seem like my friends and I were spending more on apps last year. But that's anecdotal, so I wondered: where are these revenues coming from? I opened App Store to browse the top grossing apps.

Source for an experimental 64-bit Plan 9 kernel, and supporting software. It features a revised memory-management system, MCS spin locks, and other changes to system data structures to support full 64-bit addressing. Changes to the scheduler are also planned, to improve support for multicore. Currently it supports AMD64 (x86-64, Intel 64), although parts have run on other platforms.

Drag and Drop has arrived in iOS 11! Learn the fundamentals behind the new iOS Drag and Drop - architecture and APIs. This session will go over the design goals, architecture and key components of the API to allow you to quickly adopt Drag and Drop in your App.

A demand for ransom has been made, saying that should we not comply, the files will be released to the general public. We will not be giving in to the demands of the individual or individuals that have contacted us, which might eventually lead to the files being published online. The appropriate legal authorities will be informed about the situation.

Microsoft's security team has come across a malware family that uses Intel's Active Management Technology (AMT) Serial-over-LAN (SOL) interface as a file transfer tool.

Because of the way the Intel AMT SOL technology works, SOL traffic bypasses the local computer's networking stack, so local firewalls or security products won't be able to detect or block the malware while it's exfiltrating data from infected hosts.
