  • Distributed Systems Are Hard

    A lot of the traditional mechanisms for recovering from failure may make things worse in a distributed environment. Brute force retries may flood your network, restores from backups are not straightforward. There are design patterns for addressing all of these issues but they require thought and testing.

    If there were no errors, distributed systems would be pretty easy. That can lull optimists into a false sense of security. Distributed systems must be designed to be resilient by accepting that all possible errors are just business as usual.

  • Run your Xen VMs on the SUSE Linux Enterprise Server

    While SLES does offer a specific installation pattern to make a server a Xen host, it's mainly a DYI configuration, where the installation is like any other Linux installation. There is, for instance, no notion of a storage pool easily connected to external storage; the administrator who uses all default choices ends up with locally stored VM images.

  • [elementaryOS] AppCenter & The Future of The Universe

  • Asus Tinker Board – TinkerOS_Debian V2.0.1 (Beta version)

    The Asus Tinker Board seeks to offer a good user experience for two different types of users, catering for both Linux and Android enthusiasts. While the latest Android release is no longer labelled a beta release, it still has some serious omissions. In particular, the lack of Google Play Store and a normal Android upgrade path. But on balance, I’m satisfied that Asus has met their objective of offering an attractive user experience for Android users. What about Linux users?

  • Future Proof Your SysAdmin Career: Embracing DevOps

    Sysadmins are increasingly looking to expand their skillsets and carve out new opportunities. With that in mind, many sysadmins are looking to the world of DevOps. At lots of organizations, DevOps has emerged as the most effective method for application delivery, including in the cloud.

  • Pinebook

    Anyhow, DHL also takes a fee for providing the service of paying the taxes for me. I can clear the taxes myself with customs (although they are taxes, not custom), but strangely I still have to pay the same fee to DHL. That adds another 60€ to the grand total.

    So we started with 110€ for the laptop itself plus extra storage, and have now arrived at a grand total of 213€! That certainly puts a damper on things, esp. considering that the hardware has been designed two years ago and hardly compares with even the cheapest netbooks (that can be gotten for a similar price) of 2017.

  • Twilio Voice to Pagerduty alert using Python Flask, Zappa, AWS Lambda & AWS API Gateway

    My SaaS product DevOps team at Quest Software uses several monitoring services to notice problems (hopefully before end users see them), and raises alerts for our team using PagerDuty. We also frequently need to integrate with existing company and partner products, for example our internal helpdesk and customer-facing technical-support processes. In this case, the helpdesk team wanted to have a phone number they could call to raise an alert to our team. The first suggestion was to simply put my name down as the 24×7 on-call contact, and make it my problem to alert the right people. I scoffed. We already had PagerDuty in place – why couldn’t we use that too? Simply because we didn’t have a phone number hooked up to PagerDuty. So, lets fix that.

  • Real world Performance Comparison of Samsung 960 EVO M.2 NVMe SSD and Transcend 2.5″ SATA III SSD on Linux

    Recently I bought a Samsung 960 EVO 500GB SSD to replace my Transcend 128GB SSD360S 2.5″ SATA III. Earlier this PC had this 128GB SATA III SSD for OS and 1TB Seagate Barracuda drive for data. I had not really utilised this 1TB well – data was just around 300GB. So to get faster system at the cost of underutilised free space, decided to buy Samsung 960 EVO 500GB to have both OS and data (Having more free space helps for better performance in case of SSD. So I am planning to add another 500GB to free up a lot of space on this newly purchased 500GB). Here I try to compare my earlier system with SATA SSD with new NVMe SSD. The rest of the configuration of PC is same for both the cases. I use KDE Neon (Ubuntu derivative) Linux Operating System.

And yet, for many of the tasks I want to do with it, this Raspberry Pi is no better than the 66 megahertz computer I used in college.

  • Tales of an IT professional sailing around the Antarctic loop

    Of course, that kind of rerouting wasn’t an option. Instead, Pina i Estany accessed a remote server, downloaded and compressed all the e-mails to it, and then sent those compressed files to the ship using a piece of software called Rsync, which deals very well with unstable connections. He also wrote a script that meant if the program stopped downloading at any point, it would start again from the same place once a connection was re-established.

    “So I left this program running for eight or nine hours and then opened this huge file using Thunderbird,” he said. “With that, I was able to get all the wanted e-mails, including the permits we needed.”

  • Serverless May Kill Containers [Ed: Mac Asay is not technical. So he says a buzzword will "kill" something that's a real, working implementation. That's like saying containers will "kill" containers, only you lose control over them.]

    Kubernetes, the darling of the container world, seems set to dominate the next decade of container orchestration. That is, if containers last that long.

    While it seems obvious that containers, the heir apparent to virtual machines, should have a long shelf life, the serverless boom may actually serve to cut it short. Though serverless offerings from AWS and Microsoft are built on the backs of containers, they eliminate the server metaphor entirely (and, hence, the need to containerize that server).

  • Harvey: Hurricane Preparation Tips for Data Center Managers

    As Hurricane Harvey bears down on the Texas coast, expected to make landfall around Corpus Christi either tonight or Saturday morning as a dangerous Category 3 storm, the men and women who work in data centers in the area are undoubtedly earning overtime as they prepare for the storm’s onslaught. Keeping data centers operational during natural disasters can be critical to the health and safety of the affected area’s residents, as they supply the lines of communications for many first responders and provide access to valuable information about weather conditions and the state of the area’s infrastructure.

    During pending disasters such as this, employees from Schneider Electric’s various data center divisions can often be found on the scene, offering their expertise to help data centers successfully get through the emergency. They’re good to have around, because as the old saying goes, they’ve been there and done that — countless times.

  • 35 Blockchain Startups to Watch

    There’s a reason that blockchain startups are hot. Technologies come and go over the years and raise their share of hype, but few can match the enthusiasm that has been shown for blockchain technology.

    Blockchain is the brainchild of Satoshi Nakamoto, who may or may not be real and may or may not be one person or a group of people. All that is known is that Nakamoto is also the brains behind Bitcoin. Blockchain is in fact the technology behind Bitcoin but the two are totally separate. Blockchain provides the means to record and store Bitcoin transactions, but the blockchain technology has many uses beyond Bitcoin.

  • Germans force Microsoft to scrap future pushy Windows 10 upgrades

    Microsoft sparked fury when it aggressively pushed its Windows 10 operating system onto people's PCs – from unexpected downloads to surprise installations.

    Now a consumer rights group has forced Redmond to promise it will never do it again, in Germany at least.

    In 2015, Microsoft offered existing Windows 7 and 8 users a free upgrade to its new cloud-friendly OS, and rapidly become increasingly ambitious about getting it onto machines. After bundling the upgrade alongside its monthly security patches and resorting to tricky tactics, loads of users found they were downloading gigabytes of unwanted Redmond code.

  • When Not to Use Docker: Understanding the Limitations of Containers

    Docker is a great tool. But Docker containers are not a cure-all. If you really want to understand how Docker is impacting the channel, you have to understand its limitations.

    Docker containers have become massively popular over the past several years because they start faster, scale more easily and consume fewer resources than virtual machines.

  • A Look At The Xeon Gold 6138 + Tyan GT24E-B7106 1U Linux Server Performance

  • This Stealth Warship Runs On Linux and Doesn't Need Humans to Defend Itself

    In the ongoing fight between Macs and PCs, it's hard to deny that Linux has the biggest actual firepower. Case in point: the USS Zumwalt, the most advanced surface ship in existence, which weighs in at over 10,000 tons and features 80 missile silos (its Tomahawk missiles can cover a distance of 1,550 miles), as well as a main gun that fires rocket-assisted, GPS-guided rounds (which can hit within 30 inches of a target roughly 72 miles away). What's really interesting, though, is its ability to detect, analyze, and respond to potential threats, all without the need for human intervention at all. This is where Linux comes in.

  • Fun to Play Open Source Real-Time Strategy Games – Fight for Glory

    A Real-Time Strategy (RTS) game is a time-based game which typically focuses on finding resources, managing resources, and building an empire. You can engage other players and make alliances, and find different ways to conquer foes. This type of game puts you in control of a personal army. There are no turns to take, everything takes place continuously, with players issuing commands at any time.

    RTS games have a large fan base since their inception. This game genre requires cunning, creativity, and the ability to devise innovative strategies to usurp your opponents. Some of the best known proprietary RTS series are Warcraft, Starcraft, Command & Conquer, and Age of Empires.

  • [LabPlot] Improved data fitting in 2.5
    Until now, the fit parameters could in principle take any values allowed by the fit model, which would lead to a reasonable description of the data. However, sometimes the realistic regions for the parameters are known in advance and it is desirable to set some mathematical constrains on them. LabPlot provides now the possibility to define lower and/or upper bounds for the fit parameters and to limit the internal fit algorithm to these regions only.

A woman that The Verge gave the pseudonym "Lila," provided The Verge with "both a chat log and a PGP signed and encrypted e-mail from Morgan Marquis-Boire. In the e-mail, he apologizes at great length for a terrible but unspecified wrong. And in the chat log, he explicitly confesses to raping and beating her in the hotel room in Toronto, and also confesses to raping multiple women in New Zealand and Australia."
