Linux And Windows Square Off In Another Round Of TCO Testing

Filed under
OS

Just as the debate over whether Linux or Windows is cheaper to deploy and manage was threatening to become old hat, IBM on Wednesday fired the latest salvo by promoting two reports it sponsored that indicate Linux is significantly less expensive than Windows and Unix and that Linux usage brings with it a number of secondary benefits that add intangibles to the cost argument. IBM's Linux evangelism follows Microsoft's "Get The Facts" campaign last fall that insisted Windows was the clear cost leader.

When the Robert Frances Group study, titled "TCO For Application Servers: Comparing Linux With Windows And Solaris" and commissioned by IBM, compared the cost of acquiring, implementing, and running an application server on Linux, Windows, and Sun Solaris, it found that Linux is 40% less expensive than a comparable x86-based Windows server and 54% less than a comparable Sparc-based Solaris server. The Linux server's costs were $40,149, compared with $67,559 for Windows and $86,478 for Solaris.

Robert Frances Group interviewed IT executives involved with operating-system selection and purchase decisions at more than 20 midsize to large companies that have 250 or more employees. The research firm calculated hardware-acquisition costs, software license and maintenance costs, support and systems administration costs, and application-server support and system administration costs to come up with its numbers.

The biggest disparity in costs at this time comes from Linux's lack of licensing fees, Chad Robinson, principal analyst with Robert Francis Group, said Wednesday during an IBM roundtable. But other cost-of-ownership factors that weigh in favor of Linux, according to the report, include the crossover nature of Unix and Linux skills, as well as lower ongoing support and management costs and improvements in how customers manage their Linux systems.

Graphics: Texture Compression, Enlightenment Foundation Libraries (EFL), and AMD FreeSync

  • Unity Continues Crunching More Out Of Crunch Texture Compression
    Unity is one of the big public users of the open-source Crunch DXT texture compression library. While it's no longer maintained by Rich Geldreich / Binomial, Unity has continued advancing this open-source code to further improve the compression ratio and speed. For months Unity has been talking about their promising findings with Crunch. But this is the project that Rich Geldreich, the former Valve developer, previously expressed regret having open-sourced all of it. While he is on to working on better and more advanced technologies at his Binomial startup, Unity is working to squeeze more out of this open-source library.
  • Improving EFL Graphics With Wayland Application Redraws
    Under X, application redraws are tricky to do without tearing because content can be updated at any chosen time with no clear feedback as to when the compositor will read it. EFL uses some clever tricks to this end (check out the state of the art X redraw timing for yourself), but it’s difficult to get right in all cases. For a lot of people this just works, or they’re not sensitive to the issue when it doesn’t.
  • Improved Wayland Application Redraws Coming To Enlightenment's EFL
    Samsung's Open-Source Group has been working on making their Wayland support in the Enlightenment Foundation Libraries (EFL) even better. The latest Wayland work on the Enlightenment/EFL front has been improving the application redraw process. The EFL toolkit with the upcoming v1.21 release will now be hooking into Wayland's frame callbacks to better dealing with drawing, only drawing when necessary, and doing so without the possibility of tearing.
  • AMD FreeSync For Tear-Free Linux Gaming - Current State In 2017
    If you are thinking of gifting yourself (or someone else) a FreeSync-compatible monitor this holiday season, here's a look at how the AMD FreeSync support is working right now, the driver bits you need to be aware of, and how it's all playing out for those wanting to use this tear-free capability for Linux gaming.

KStars 2.8.9 is released!

Here comes the last KStars release for 2017! KStars v2.8.9 is available now for Windows, MacOS, and Linux. Robert Lancaster worked on improving PHD2 support with Ekos. This includes retrieving the guide star image, drift errors and RMS values, among other minor improvements and refactoring of the Ekos PHD2 codebase to support future extensions. Read more

Security: Mirai, Vista 10, Starbucks, and Hacking Team Investigation

  • Mirai IoT Botnet Co-Authors Plead Guilty

    The U.S. Justice Department on Tuesday unsealed the guilty pleas of two men first identified in January 2017 by KrebsOnSecurity as the likely co-authors of Mirai, a malware strain that remotely enslaves so-called “Internet of Things” devices such as security cameras, routers, and digital video recorders for use in large scale attacks designed to knock Web sites and entire networks offline (including multiple major attacks against this site).

  • Google Researcher Finds Flaw in Pre-Installed Windows 10 Password Manager
    Google security researcher Tavis Ormandy, who has previously discovered, reported, and disclosed several major bugs in Windows and its features, came across a new security vulnerability affecting Microsoft users. This time, the flaw exists in the Keeper password manager that comes pre-installed in some Windows 10 versions, with Ormandy explaining that it’s similar to a vulnerability that he discovered in August 2016. “I remember filing a bug a while ago about how they were injecting privileged UI into pages,” Ormandy explained on December 14. “I checked and, they're doing the same thing again with this version,” he continues.
  • Starbucks Wi-Fi Turned People’s Laptops into Cryptocurrency Miners
    The free Wi-Fi that the Buenos Aires Starbucks offers to its customers was being used to mine for cryptocurrency, and what’s worse, it used people’s laptops to do it. The whole thing was discovered by Stensul CEO Noah Dinkin who actually paid a visit to the store and wanted to browse the web using the free Wi-Fi, only to discover that his laptop was unknowingly converted into a cryptocurrency miner. He then turned to Twitter to ask Starbucks if they know about the what he described as bitcoin mining taking place without customers knowing about it. “Hi Starbucks, did you know that your in-store wifi provider in Buenos Aires forces a 10 second delay when you first connect to the wifi so it can mine bitcoin using a customer's laptop? Feels a little off-brand,” he said in his tweet.
  • Italian Prosecutor Makes Request to Close Hacking Team Investigation
    The damaging data breach that exposed the secrets of an infamous surveillance tech company might go unsolved forever. After more than two years, the Italian prosecutor who was investigating the attack on the Milan-based Hacking Team has asked the case to be dismissed, according to multiple sources. On Monday, the Milan prosecutor Alessandro Gobbis sent a notice to the people under investigation informing them that he had sent the judge a request to shut down the investigation, according to a copy of the document obtained by Motherboard.
