Leslie Zhai Talks 20 Years of KDE in China

Filed under

In 2002, as a computer science major university student, I went to a Legal Authoried software store in Wuhan, Guangputun, and bought Redhat7 including four install CDs, three src.rpm CDs and a very exquisite user manual for only RMB 50, because other software for Windows 98 was too expensive to a univerty student! It was my first time to use KDE 3. Yes I chose KDE as my default desktop enviroment, but I tried GNOME of course. Wink Then I tried to migrate my university's course assignment developed in Turbo C to compile with GCC. I used Konsole and VIM to edit my source code, I tried Emacs but I did not know how to make coffee with it, so I switched to VIM Wink and my teachers switched to use Redhat8 instead of Windows 98 when teaching operating system courses.

How Apache Kafka is powering a real-time data revolution

Filed under

There are several things to think about while building a company, but the ones that are particularly critical for building a successful company based on an open source technology are evangelism, community influence, the business model, and having the pragmatism to balance investment across these areas. Open source technology greatly simplifies the adoption problem for a new technology and empowers developers to use the technology that is right for building products. Essentially, the developer is the new buyer.

Why enterprises are now opting for open source software

Filed under
Red Hat

In March this year, Red Hat became the world’s first open source software (OSS) solutions company to cross $2 billion in revenue. The term open source implies ‘free’ access to software which developers can modify. Not many thought Red Hat would be successful when the company was founded in 1993. However, it has proved its naysayers wrong with a $14.78 billion market cap (as on September 30), $600 million revenue in Q2 FY17 and entry into the Forbes list of the World’s Most Innovative Companies in 2016 for the fourth time. Jim Whitehurst, Red Hat’s president and CEO, and Rajesh Rege, its India MD, tell Forbes India why enterprises are now opting for open source software.

elementary OS 0.4: Review and interview with the founder

Filed under

Last month the elementary team released elementary OS “Loki” 0.4.

Needless to say, I wasted no time downloading and installing that bad boy on one of my machines. Even though I tend to use openSUSE on most of my desktops and laptops, I’ve had a soft spot for elementary since its very first release. It’s always been a high-quality, polished system—and the team behind it clearly care a great deal about the user experience.

Couchbase and the future of NoSQL databases

Filed under

Well, I've built and led developer communities for 10+ years at Sun, Oracle, and Red Hat, so I have experience in leading crossfunctional teams to develop and execute strategy, planning, and execution of content, and marketing campaigns and programs. I've also led engineering teams at Sun, and I’m a founding member of the Java EE team.

At Couchbase, a developer advocate helps developers become effective users of a technology, product, API, or platform. This can be done by sharing knowledge about the product using the medium where developers typically hangout. Some of the more common channels include blogs, articles, webinars, and presentations at conferences and meetups. Answering questions on forums and Stack Overflow, conversations on social media, and seeking contributors for open source projects are some other typical activities that a developer advocate performs on a regular basis.

2016 LiFT Scholarship Winner Lorien Smyer: Bookkeeper Turned Technologist

Filed under

I was a bookkeeper for many years. Long ago, I had to hand-enter all data to a paper spreadsheet with a pencil.

When my clients started getting computers, I was fascinated by everything about these amazing tools: the hardware, the software, how customizable it all was. In my spare time, I started taking occasional computer-related classes at my local community college, and doing many IT-related tasks for my clients, in addition to the bookkeeping I was already doing for them.

In 1995, I met the man who became my husband. He got a personal computer that same year, and happily allowed me to become our home IT expert.

The Open Source Era: A Q&A With Canonical CEO Jane Silber

Filed under

Canonical, a 750-person company with employees in more than 42 countries around the world, is the driving force behind Ubuntu open-source software. Although Canonical and Ubuntu are well-known and well-respected among hardcore technologists, most consumers have probably never heard of either.

This is an unfortunate reality of open-source software. Products and projects dedicated to democratizing technology by making computer use free and fair for everyone often fly under the radar. Whether Canonical and Ubuntu become synonymous with the general consumer is largely dependent on whether or not consumers move away from traditional device usage. Can Canonical's vision for a converged computing experience across a spectrum devices make the Canonical name as synonymous with desktop users as it is with users of its enterprise cloud and application performance management (APM) solutions?

I chatted with Canonical CEO Jane Silber, a remarkable executive with a rich technological background, over email about the challenges Canonical faces in consumer computing and even television, as well as how the company plans to maintain its status in the enterprise cloud and software markets.

Chatting with Google’s Hiroshi Lockheimer about Pixel, Android OEMs, and more

Filed under

There were big changes announced at Google this week as the company's "Google Hardware" team came out of hiding and announced a slew of products. The star of the show was definitely the Google Pixel, Google's new pair of smartphones that the company is saying it designed while using HTC as a manufacturer. The advent of Pixel phones means Google is an Android OEM again, harkening back to the days when it owned Motorola. This time, though, the company is serious about hardware and software integration.

Android, however, is the world's most popular operating system because of OEM partners like Samsung, Huawei, Xiaomi, and LG. And if Google wants Android to continue to deliver Google services to billions of people, it will still need all those partners. Google once again has a delicate balancing act to pull off. The company must do its best to deliver a Google-y Android phone while not stealing the thunder from other OEMs or putting them at a serious competitive disadvantage.

Solving the Linux kernel code reviewer shortage

Filed under

Operating system security is top of mind right now, and Linux is a big part of that discussion. One of the questions to be solved is: How do we ensure that patches going upstream are properly reviewed?

Wolfram Sang has been a Linux kernel developer since 2008, and frequently talks at Linux conferences around the world, like LinuxCon Berlin 2016, about ways to improve kernel development practices.

Let's get his point of view.

Security News

  • Free tool protects PCs from master boot record attacks [Ed: UEFI has repeatedly been found to be both a detriment to security and enabler of Microsoft lock-in]
    Cisco's Talos team has developed an open-source tool that can protect the master boot record of Windows computers from modification by ransomware and other malicious attacks. The tool, called MBRFilter, functions as a signed system driver and puts the disk's sector 0 into a read-only state. It is available for both 32-bit and 64-bit Windows versions and its source code has been published on GitHub. The master boot record (MBR) consists of executable code that's stored in the first sector (sector 0) of a hard disk drive and launches the operating system's boot loader. The MBR also contains information about the disk's partitions and their file systems. Since the MBR code is executed before the OS itself, it can be abused by malware programs to increase their persistence and gain a head start before antivirus programs. Malware programs that infect the MBR to hide from antivirus programs have historically been known as bootkits -- boot-level rootkits. Microsoft attempted to solve the bootkit problem by implementing cryptographic verification of the bootloader in Windows 8 and later. This feature is known as Secure Boot and is based on the Unified Extensible Firmware Interface (UEFI) -- the modern BIOS.
  • DDOS Attack On Internet Infrastructure
    I hope somebody's paying attention. There's been another big DDOS attack, this time against the infrastructure of the Internet. It began at 7:10 a.m. EDT today against Dyn, a major DNS host, and was brought under control at 9:36 a.m. According to Gizmodo, which was the first to report the story, at least 40 sites were made unreachable to users on the US East Coast. Many of the sites affected are among the most trafficed on the web, and included CNN, Twitter, PayPal, Pinterest and Reddit to name a few. The developer community was also touched, as GitHub was also made unreachable. This event comes on the heels of a record breaking 620 Gbps DDOS attack about a month ago that brought down security expert Brian Krebs' website, KrebsonSecurity. In that attack, Krebs determined the attack had been launched by botnets that primarily utilized compromised IoT devices, and was seen by some as ushering in a new era of Internet security woes.
  • This Is Why Half the Internet Shut Down Today [Update: It’s Getting Worse]
    Twitter, Spotify and Reddit, and a huge swath of other websites were down or screwed up this morning. This was happening as hackers unleashed a large distributed denial of service (DDoS) attack on the servers of Dyn, a major DNS host. It’s probably safe to assume that the two situations are related.
  • Major DNS provider Dyn hit with DDoS attack
    Attacks against DNS provider Dyn continued into Friday afternoon. Shortly before noon, the company said it began "monitoring and mitigating a DDoS attack" against its Dyn Managed DNS infrastructure. The attack may also have impacted Managed DNS advanced service "with possible delays in monitoring."
  • What We Know About Friday’s Massive East Coast Internet Outage
    Friday morning is prime time for some casual news reading, tweeting, and general Internet browsing, but you may have had some trouble accessing your usual sites and services this morning and throughout the day, from Spotify and Reddit to the New York Times and even good ol’ For that, you can thank a distributed denial of service attack (DDoS) that took down a big chunk of the Internet for most of the Eastern seaboard. This morning’s attack started around 7 am ET and was aimed at Dyn, an Internet infrastructure company headquartered in New Hampshire. That first bout was resolved after about two hours; a second attack began just before noon. Dyn reported a third wave of attacks a little after 4 pm ET. In all cases, traffic to Dyn’s Internet directory servers throughout the US—primarily on the East Coast but later on the opposite end of the country as well—was stopped by a flood of malicious requests from tens of millions of IP addresses disrupting the system. Late in the day, Dyn described the events as a “very sophisticated and complex attack.” Still ongoing, the situation is a definite reminder of the fragility of the web, and the power of the forces that aim to disrupt it.
  • Either IoT will be secure or the internet will be crippled forever
    First things first a disclaimer. I neither like nor trust the National Security Agency (NSA). I believe them to be mainly engaged in economic spying for the corporate American empire. Glenn Greenwald has clearly proven that in his book No Place to Hide. At the NSA, profit and power come first and I have no fucking clue as to how high they prioritize national security. Having said that, the NSA should hack the Internet of (insecure) Things (IoT) to death. I know Homeland Security and the FBI are investigating where the DDoS of doomsday proportions is coming from and the commentariat is already screaming RUSSIA! But it is really no secret what is enabling this clusterfuck. It’s the Mirai botnet. If you buy a “smart camera” from the Chinese company Hangzhou XiongMai Technologies and do not change the default password, it will be part of a botnet five minutes after you connect it to the internet. We were promised a future where we would have flying cars but we’re living in a future where camera’s, light-bulbs, doorbells and fridges can get you in serious trouble because your home appliances are breaking the law.
  • IoT at the Network Edge
    Fog computing, also known as fog networking, is a decentralized computing infrastructure. Computing resources and application services are distributed in logical, efficient places at any points along the connection from the data source (endpoint) to the cloud. The concept is to process data locally and then use the network for communicating with other resources for further processing and analysis. Data could be sent to a data center or a cloud service. A worthwhile reference published by Cisco is the white paper, "Fog Computing and the Internet of Things: Extend the Cloud to Where the Things Are."
  • Canonical now offers live kernel patching for Ubuntu 16.04 LTS users

With the release of Linux 4.0, users have been able to update their kernel packages without rebooting, however, Ubuntu will be the first distribution to offer this feature for free.
  • ​The Dirty Cow Linux bug: A silly name for a serious problem
    Dirty Cow is a silly name, but it's a serious Linux kernel problem. According to the Red Hat bug report, "a race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system."
