Can't libc Do It?

Filed under

linux devcenter: I have a little PIR program that prints “Hello, world!”. I use it for valgrinding Parrot. Profiling Parrot’s startup and shutdown time seemed useful. When you do this, run callgrind annnotate on the resulting output file to get a nice report of which functions did the most work. Here’s what happened when I dug into the code.

Linux, Still not there yet

Filed under

Al Suttons Blog: I’ve finally made the choice between OpenSuSE or Vista as my preferred OS for the next few years, and the decision went to Vista, and to my surprise it only took a couple of hours to decide.

ATI Drivers: Ubuntu vs. Windows

Filed under

Phoronix: NVIDIA's Linux and Windows drivers perform about the same and in some instances the Linux binary driver even running faster, but as we have been sharing now for many months the Linux fglrx driver is handicapped for performance. Has things since improved for ATI?

The KDE 3.5 Control Center - Part 9 - Sound & Multimedia

Filed under

The Sound & Multimedia section covers four basic areas of the KDE multimedia system that are important to your daily use of KDE from a multimedia perspective. As much as we may or may not realize it, we rely on a lot of multimedia interaction with our computers every day. Be it music, video or something else, it's all very important to us and without it, our experience wouldn't be the same. So lets look at each of the four subsections in this section and how each one is important to your daily user experience.

Firefox extension lets you remove elements from Web pages

Filed under
Moz/FF Are you irritated by huge graphical ads smack in the middle of an article? Or maybe you don't want to waste bandwidth viewing the dozens of images in a review, or user icons in forum boards? You can remove them for good with a single click by using Firefox's RIP extension, which zaps anything out of a Web page, permanently.

Why Microsoft Will Not Sue Linux Patent Violators

Filed under

OSWeekly: Every place you look, someone is going on and on about how Microsoft is planning to litigate everyone who has violated their patents. Well, today I‘m going to explain why I don't believe Microsoft will even bother with it, what they ought to do if they were smart and why we have nothing to worry about.

Small Builders Feel The Software Love

Filed under

CRN: Custom systems builders may not get the same amount of attention and other perks that name-brand OEMs get from software vendors like Microsoft and Novell. But those vendors say they recognize the importance of systems builders and are taking steps to recruit and retain them.

Macintosh…Help me understand why

Filed under

ZDNet: I can feel them…the flames…they’re coming. But I have to ask this question again (yes, I’ve asked one very much like it before) in light of recent events. The recent events, of course, involve the release of a particular Linux distribution with a funny African sort of name and, maybe more significantly, the first tier-one vendor’s adoption of said funny-sounding distro as an OS choice.

GPLv3 threatens Microsoft-Novell pact?

Filed under

ZDNet: While much of what was (officially) released is known, Novell did express concerns that the final version of the General Public License (GPLv3) -- which slipped its March 2007 deadline -- could see Microsoft halting the distribution of SUSE Linux, which would impact financially on Novell.

Make Wine and PulseAudio get along

Filed under

Thursday Night: I got a Joost invite the other day, and I tried to get the client program working with Wine, the Linux implementation of the Win32 API. Sadly, it was a no-go; I couldn’t get it to work without skipping. However, it’s not all lost.

Red Hat advises caution over patents

Filed under

iTWire: Red Hat's Mark Webbink is not the sort of person to issue threats. He's somewhat unusual in that he's a legal counsel who uses clear, concise prose when he speaks. Like all those in the profession, he does speak carefully but thankfully his speech is free of obfuscation.

Game Emulation In Linux

Filed under
Gaming A common complaint about Linux is that there is a general lack of games. When emulation is brought into the picture though, it opens up a huge world of gaming possibilities. In this article, we will be looking into what emulation is, installing a gamepad and taking a look at a selection of emulators for different consoles.

Desktop search tools for GNU/Linux: the competition hots up (part one)

Filed under

Free Software Magazine: I sometimes think that search tools are like my local bus: none comes along for ages and then three turn up in quick succession. For quite some time Beagle and Kat have been meeting the needs of users like you and me who fill up their hard drives with the results of our internet meanderings and because we have been remiss in keeping those drives well organized we eventually have to use search tools to find that PDF or HTML article we spent an eternity looking for.

Video's Missing Metadata

Filed under

Linux App Finder: Where is the metadata standard for video? MP3's have ID3. Images have EXIF, IPTC, and more. If commercial video is ever to take off as an electronically distributed format it's necessary. Without it video players can't identify what's available. That may not seem important if you are sitting in front of a computer and reading a filename, but for other devices and 10' UI's it's a big problem.

Novell document dump makes it look like a scandal

Filed under

Dana Blankenhorn: The Washington game of dumping incriminating documents late on a Friday is well-known. When someone does it, suspicions are raised. Now Novell has done just that.

A Look Ahead at Thunderbird 3

Filed under

CyberNetNews: I noticed today that the Mozilla Thunderbird wiki page had been updated with some of their plans for version 3. There isn’t much information provided, but there are two things they mention that I’m really excited to see in the next release.

Linux 4.8.4

I'm announcing the release of the 4.8.4 kernel. And yeah, sorry about the quicker releases, I'll be away tomorrow and as they seem to have passed all of the normal testing, I figured it would be better to get them out earlier instead of later. And I like releasing stuff on this date every year... All users of the 4.8 kernel series must upgrade. The updated 4.8.y git tree can be found at: git:// linux-4.8.y and can be browsed at the normal git web browser: Read more Also: Linux 4.7.10 Linux 4.4.27

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
    Canonical has announced its ‘Livepatch Service’ which any user can enable on their current installations to eliminate the need for rebooting their machine after installing an update for the Linux kernel. 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."
