How Twitter Rebuilt Google’s Secret Weapon

Posted on by

Borg is a way of efficiently parceling work across Google’s vast fleet of computer servers, and according to Wilkes, the system is so effective, it has probably saved Google the cost of building an extra data center. Yes, an entire data center. That may seem like something from another world — and in a way, it is — but the new-age hardware and software that Google builds to run its enormous online empire usually trickles down to the rest of the web. And Borg is no exception.

At Twitter, a small team of engineers has built a similar system using a software platform originally developed by researchers at the University of California at Berkeley. Known as Mesos, this software platform is open source — meaning it’s freely available to anyone — and it’s gradually spreading to other operations as well.

New Skype malware spreading at 2,000 clicks per hour makes money by using victims’ machines to mine Bitcoins

To avoid this threat and others like it, don’t click on random links you receive on Skype. You’ll be doing yourself a favor, helping stop the spread of malware, and ensuring criminals get a smaller pay day.

via New Skype malware spreading at 2,000 clicks per hour makes money by using victims’ machines to mine Bitcoins – The Next Web.

At least it’s just bitcoin mining and not stealing credentials.  This is why I always have three performance monitors on my dashboard; CPU usage, bandwidth, and memory.  With this piece of malware you would immediately see a problem because the CPU monitor shouldn’t be full of color.  Then simply take the PC offline and do some investigation or bring it to someone.  On Windows machines there’s Perfmon to look at these performance monitors.  Just like a car has its fuel and temperature guages, computer users would be far more secure getting used to performance monitor guages.  I often wonder why distributors don’t display these somewhere as a default option much like they have for the clock.

Intel’s Haswell Takes A Major Step Forward; Integrates Voltage Regulator

Posted on by

Haswell incorporates a refined VRM on-die that allows for multiple voltage rails and controls voltage for the CPU, on-die GPU, system I/O, integrated memory controller, as well as several other functions. Intel refers to this as a FIVR (Fully Integrated Voltage Regulator), and it apparently eliminates voltage ripple and is significantly more efficient than your traditional motherboard VRM. Added bonus? It’s 1/50th the size.

How the 2013 World Press Photo of the Year was faked with Photoshop

Posted on by

Basically, as far as we can surmise, Hansen took a series of photos — and then later, realizing that his most dramatically situated photo was too dark and shadowy, decided to splice a bunch of images together and apply a liberal amount of dodging (brightening) to the shadowy regions. For what it’s worth, Hansen claims that the light in the alley was natural — and to be fair, sometimes magical lighting does occur. I think most of you will agree, though, that the photo simply feels fake — there’s just something about the lighting that sets off a warning alarm in your brain. As for why World Press Photo didn’t forensically analyze the photo using freely available, advanced, accurate analysis tools such as FourMatch or FotoForensics… who knows.

Open Compute to open source high-end network switches

Posted on by

That said, many high-speed switches today use BSD Unix as their basis. While many say that the OCP is starting with a “clean sheet of paper”, the ultimate goal of the project seems to be to give datacenter administrators a “bare metal network switch”. I think it’s likely that BSD will lie at its heart. After all, why reinvent the wheel?

The British ‘Atlantis’ is mapped in detail

Posted on by

The camera uses high frequency sound and acoustic lenses to refract sound waves and create film footage without light. The technology is usually reserved for creating a fly-by of sunken ships, but it has now picked up the wreckage of the former trading hub in astonishing detail. In addition, old naval navigation charts helped in the tracking and mapping of where the former coastline stood.

Meanwhile in Brazil, the discovery of a large lump of granite rock 1,500km (932 miles) off the coast of Rio de Janeiro has led to claims that the real Atlantis has been discovered.

How to Retreive Expired Snapchat Photos

Posted on by

Snapchat moves “upward of 150 million photos through the service on a daily basis.” Compared to Facebook’s Instagram, which moves 40 million photos a day, that is a lot of photos moved for such a new company. The app differs in the fact that images and videos are ephemeral rather than permanent, something that is attractive to teens and young adults.

via Snapchat – 4-30-13.

I suspected the ephemeral nature of Snapchat was a mirage but surprised at how simple they made it.  It is impossible to do what Snapchat claims because a simple screen grabbing app on the receiving end could also capture any photo or chat blurb before expiration.  I am surprised at how large Snapchat has become.  Here’s a pertinent blurb as to where the expired image files are stored.  The original article gets into more detail.

Each of the images within the received_image_snaps folder had a .nomedia extension appended to the end of the file name. For example, the name of the file figure 3 is “h1a81hurcs00h1365528700423.jpg.nomedia”. This was likely done to prevent the images stored within this directory from being placed in the gallery or from being scanned by the media store. AccessData’s Forensic Toolkit recognized the .nomedia extension that was appended to the end of the file name and ignored it, displaying the images.

Goldman Sachs employees concerned Bloomberg news reporters are using terminals to snoop

Goldman later learned that Bloomberg staffers could determine not only which of its employees had logged into Bloomberg’s proprietary terminals but also how many times they had used particular functions, insiders said.
