Efficient storage: how we went down from 50 PB to 32 PB

As the Russian rouble exchange rate slumped two years ago, it drove us to think of cutting hardware and hosting costs for the Mail.Ru email service. To find ways of saving money, let’s first take a look at what emails consist of.

Indexes and bodies account for only 15% of the storage size, whereas 85% is taken up by files. So, files (that is attachments) are worth exploring in more detail in terms of optimization. At that time, we didn’t have file deduplication in place, but we estimated that it could shrink the total storage size by 36% since many users receive the same messages, such as price lists from online stores or newsletters from social networks containing images and so on. In this article, I’m going to describe how we implemented a deduplication system under the supervision of Albert Galimov.

Worth Reading: Getting started with coding

If you work with computers in any aspect of your life, being able to code can be a very powerful tool. All too often however, I hear people say things like “it’s too difficult” or “I’m not a developer” and they never take more than their first few steps. This post, the first in a series on getting started with coding, addresses both the fears of taking your first steps and the benefits of starting that journey. The remaining posts then give you all the help you need to overcome those perceived obstacles and have some fun along the way. —vegaskid

Cops to increasingly use digital footprints from IoT devices for investigations

If Mark Stokes, Scotland Yard’s head of digital, cyber and communications forensics unit, is correct, then IoT devices will play an increasingly important role in crime scene investigations. “The crime scene of tomorrow is going to be the internet of things,” Stokes told the Times.The police are being trained to look for “digital footprints” – IoT gadgets that “track or record activities” which might prove or disprove alibis and witness statements as well as record what occurred during a murder victim’s final moments.Cops will be relying on evidence from smart devices which spy on you – such as internet connected refrigerators, light bulbs, washing machines, vacuum cleaners, coffee makers and voice-controlled robotic assistants.To read this article in full or to leave a comment, please click here

Cops to increasingly use digital footprints from IoT devices for investigations

Hands on: Dell twists the XPS 13 into a 2-in-1

Dell has just improved its already brilliant XPS 13 -- it will now be available as a 2-in-1, which means the device has the versatility to be a laptop or a tablet. I had the chance to play around with the device prior to CES. It has a clever design and wowed me with its sleek design and edge-to-edge screen, but it won't come cheap. The starting price of the XPS 13 2-in-1 is US$999, and it'll start shipping this month. That's about $200 more than the starting price of the XPS laptop. You are paying more for the versatility of the XPS 13 2-in-1. On the outside, the XPS 13 2-in-1 looks like the XPS 13 laptop, but Dell has changed the hinge connecting the keyboard base and screen. The screen can be rotated 360 degrees to turn the device into a tablet.To read this article in full or to leave a comment, please click here

How to hang on to Windows 7 for the long run

If Windows 7 represents peak Windows for you, you’re not alone. Twice as many people use Win7 as use Win10, even after 18 months of Microsoft pressure to get you to give up Win7 and jump to the shiny new version as your operating system of choice.Your reasons for staying with Win7 may range from mere convenience to mental inertia to an abject fear of the Win10 info borg. Whatever your reasons for remaining with Win7, there are steps you can take right now to ensure Win7 keeps working -- at least until Microsoft pulls the plug on security patches, on Jan. 14, 2020.

How to handle business continuity in a crisis

Keeping the lights onImage by ThinkstockMost businesses are critically reliant upon their IT systems. If these systems go down due to a natural disaster, temporary power outage, loss of data center, ransomware or hacker attack, lost or corrupted files, or an application failure due to a software virus, the results can inflict significant financial harm. In the worst case, the business will be unable to continue functioning.To read this article in full or to leave a comment, please click here

Why employees don’t use collaboration tools

Slack exploded onto the scene three years ago, and since then just about everyone from industry giants like Facebook to small groups of open source developers have been getting in on the team collaboration software act.Today the pace of collaboration software development and innovation is frenetic, and according to research by G2 Crowd, a peer-to-peer business review platform, the boom in corporate adoption shows no sign of slowing down in the near future. It found that more than half of all companies have already implemented team collaboration solutions of one kind or another, and 31 percent plan to adopt one in the next two years.To read this article in full or to leave a comment, please click here

Yang Explorer in a Docker container

My Personal Look Back on 2016

I haven’t ever written a “year in review” type of post before. Sure, I do a post to summarize how the blog has done over the year but I’ve never done a personal look back. Last night–New Years Eve–I was thinking about everything that I was involved in during 2016 and I realized “I should write this down! I was involved in or a participant of some amazing things last year!”

So here we go. In an effort to show a more personal side and not just my geeky side, here is my personal 2016 year in review.

Got Married

In February, my then-girlfriend and I got married! I know everyone says their wedding was the best, but ours totally was! Trust me! In all honesty, it was one of the funnest days of my life. Full credit to my wife for planning what was essentially an awesome party with our families and closest friends. Oh, and the venue and staff were absolutely amazing as well which sealed the deal as the greatest wedding ever .

Bringing 2017 To Everyone

It’s time once again for my traditional New Year’s Day navel gazing. As per tradition with my blog, I’m not going to make prognostications about networking or IT in general. Either I’m going to wind up totally wrong or be totally right and no one will care. I rather enjoy the ride as we go along, so trying to guess what happens is kind of pointless.

Instead, I’m going to look at what I want to accomplish in the coming year. It gives me a chance to analyze what I’m doing and what I want to be working on. And it’s a whole lot easier than predicting that SDN is going to take everyone’s job or OpenFlow being dead again.

Write Like the Wind

My biggest goal for 2016 was to write more. And that I did. I worked in writing any time I could. I wrote about ONUG, SD-WAN, and other fun topics. I even wrote a small book! Finding time to work all the extra typing in to my Bruce Wayne job at Tech Field Day was a bit challenging here and there. And more than once I was publishing a blog post at the deadline. But all Continue reading

Summary of Pol Pot: Anatomy of a Nightmare

Overview

I’ve decided to start a reading project on genocides and violent totalitarian dictators. Most education about these topics in the US is focused around Nazi Germany, or occasionally the Soviet Union under Stalin. While I’d like to come back to those events if I can endure the topic that long, I’m starting with non-Western events.

First up is Pol Pot and the Khmer Rouge, partly because I grew up in the 1980s around a lot of first or second-generation Cambodian and Vietnamese immigrants, but never knew much about the politics behind their flight from Southeast Asia. It’s a particularly strange case of different cultural, political, and historic influences converging in a disastrous way. The term “genocide” has been controversial with reference to the Khmer Rouge regime: while they systematically murdered or starved somewhere between 1.7 and 2.3 million people, for the most part the killings didn’t target a specific racial, ethnic, or religious group. While there were certainly elements of this – as I’ll discuss – Pol Pot’s regime was more about brutal slavery and vicious punishment of any deviance, regardless of the person.
