Reddit: Does anyone do analysis of Mac OS X updates to understand what code is being updated?

Thursday 22nd of February 2018 06:59:11 AM

I just got this message on my mac to restart for updates and it made me wonder:

Why do I need to restart the computer if the only update is for the Messages app?

I'd like to know more about that update that is going to be installed on my computer, essentially. Is there a website that does analysis already or can someone point me in the right direction to the analysis myself?

TuxMachines: Events: FOSDEM Samba Talks, USENIX Enigma, LCA (linux.conf.au) and FAST18

Thursday 22nd of February 2018 06:49:01 AM
  • Authentication and authorization in Samba 4

    Volker Lendecke is one of the first contributors to Samba, having submitted his first patches in 1994. In addition to developing other important file-sharing tools, he's heavily involved in development of the winbind service, which is implemented in winbindd. Although the core Active Directory (AD) domain controller (DC) code was written by his colleague Stefan Metzmacher, winbind is a crucial component of Samba's AD functionality. In his information-packed talk at FOSDEM 2018, Lendecke said he aimed to give a high-level overview of what AD and Samba authentication is, and in particular the communication pathways and trust relationships between the parts of Samba that authenticate a Samba user in an AD environment.

  • Two FOSDEM talks on Samba 4

    Much as some of us would love never to have to deal with Windows, it exists. It wants to authenticate its users and share resources like files and printers over the network. Although many enterprises use Microsoft tools to do this, there is a free alternative, in the form of Samba. While Samba 3 has been happily providing authentication along with file and print sharing to Windows clients for many years, the Microsoft world has been slowly moving toward Active Directory (AD). Meanwhile, Samba 4, which adds a free reimplementation of AD on Linux, has been increasingly ready for deployment. Three short talks at FOSDEM 2018 provided three different views of Samba 4, also known as Samba-AD, and left behind a pretty clear picture that Samba 4 is truly ready for use. I will cover the first two talks in this article, and the third in a later one.

  • A report from the Enigma conference

    The 2018 USENIX Enigma conference was held for the third time in January. Among many interesting talks, three presentations dealing with human security behaviors stood out. This article covers the key messages of these talks, namely the finding that humans are social in their security behaviors: their decision to adopt a good security practice is hardly ever an isolated decision.

    Security conferences tend to be dominated by security researchers demonstrating their latest exploits. The talks are attack-oriented, they keep a narrow focus, and usually they close with a dark outlook. The security industry has been doing security conferences like this for twenty years and seems to prefer this format. Yet, if you are tired of this style, the annual USENIX Enigma conference is a welcome change of pace. Most of the talks are defense-oriented, they have a horizon going far beyond technology alone, and they are generally focused on successful solutions.

  • DIY biology

    A scientist with a rather unusual name, Meow-Ludo Meow-Meow, gave a talk at linux.conf.au 2018 about the current trends in "do it yourself" (DIY) biology or "biohacking". He is perhaps most famous for being prosecuted for implanting an Opal card RFID chip into his hand; the Opal card is used for public transportation fares in Sydney. He gave more details about his implant as well as describing some other biohacking projects in an engaging presentation.

    Meow-Meow is a politician with the Australian Science Party, he said by way of introduction; he has run in the last two elections. He founded BioFoundry, which is "Australia's first open-access molecular biology lab"; there are now two such labs in the country. He is also speaks frequently as "an emerging technology evangelist" for biology as well as other topics.

  • Notes from FAST18

    I attended the technical sessions of Usenix's File And Storage Technology conference this week. Below the fold, notes on the papers that caught my attention.

TuxMachines: Security: Vista10 and uTorrent Holes Found by Google

Thursday 22nd of February 2018 06:32:02 AM
  • Google drops new Edge zero-day as Microsoft misses 90-day deadline

    Google originally shared details of the flaw with Microsoft on 17 November 2017, but Microsoft wasn’t able to come up with a patch within Google’s non-negotiable “you have 90 days to do this” period.

  • Google Goes Public with Another Major Windows 10 Bug

    After revealing an Edge browser vulnerability that Microsoft failed to fix, Google is now back with another disclosure, this time aimed at Windows 10 Fall Creators Update (version 1709), but potentially affecting other Windows versions as well.

    James Forshaw, a security researcher that’s part of Google’s Project Zero program, says the elevation of privilege vulnerability can be exploited because of the way the operating system handles calls to Advanced Local Procedure Call (ALPC).

    This means a standard user could obtain administrator privileges on a Windows 10 computer, which in the case of an attack, could eventually lead to full control over the impacted system.

    But as Neowin noted, this is the second bug discovered in the same function, and both of them, labeled as 1427 and 1428, were reported to Microsoft on November 10, 2017. Microsoft said it fixed them with the release of the February 2018 Patch Tuesday updates, yet as it turns out, only issue 1427 was addressed.

  • uTorrent bugs let websites control your computer and steal your downloads

    The vulnerabilities, according to Project Zero, make it possible for any website a user visits to control key functions in both the uTorrent desktop app for Windows and in uTorrent Web, an alternative to desktop BitTorrent apps that uses a web interface and is controlled by a browser. The biggest threat is posed by malicious sites that could exploit the flaw to download malicious code into the Windows startup folder, where it will be automatically run the next time the computer boots up. Any site a user visits can also access downloaded files and browse download histories.

  • BitTorrent Client uTorrent Suffers Security Vulnerability (Updated)

    BitTorrent client uTorrent is suffering from an as yet undisclosed vulnerability. The security flaw was discovered by Google security researcher Tavis Ormandy, who previously said he would reveal a series of "remote code execution flaws" in torrent clients. BitTorrent Inc. has rolled out a 'patch' in the latest Beta release and hopes to fix the stable uTorrent client later this week.

Reddit: Is there a pseudo-ai bash chat app?

Thursday 22nd of February 2018 05:57:00 AM

whoami returns your username, which is neat, but if you were to tell the terminal neat, nothing happens. This got me thinking along the lines of moo or cowsay and other Linux easter eggs if there was some back and forth pseudo-chat app already made. Obviously it's not difficult to make, but there's nothing quite like chatting with someone else's fake bot.

I guess something along the lines of visudo, but more extensive.

TuxMachines: KDE Says Its Next Plasma Desktop Release Will Start a Full Second Faster

Thursday 22nd of February 2018 01:54:50 AM

According to the developer, the upcoming KDE Plasma 5.13 desktop environment release will start a full second faster than previous versions because of the removal of the QmlObjectIncubationController component, which apparently slowed down the entire desktop, and promises to let users pin apps on the panel that contain spaces in their desktop file names.

Goodies are also coming to the upcoming KDE Applications 18.04 software suite this spring, which makes creating of new files with the Dolphin file manager instantaneous, improves drag-and-drop support from Spectacle to Chromium, and lets users configure the Gwenview image viewer to no longer display the image action buttons on thumbnails when they hover with the mouse cursor over them.

TuxMachines: Why open source could be IBM's key to future success in the cloud

Thursday 22nd of February 2018 01:49:47 AM

Do those same developers need IBM? Developers certainly benefit from IBM's investments in open source, but it's not as clear that those same developers have much to gain from IBM's cloud. Google, for example, has done a stellar job open sourcing code like TensorFlow and Kubernetes that feeds naturally into running related workloads on Google Cloud Platform. Aside from touting its Java bonafides, however, IBM has yet to demonstrate that developers get significant benefits for modern workloads on its cloud.

That's IBM's big challenge: Translating its open source expertise into real, differentiated value for developers on its cloud.

Phoronix: Wine-Staging Has Been Revived, Working Towards New Release

Thursday 22nd of February 2018 01:30:00 AM
Wine-Staging has been a flavor of Wine popular with Linux gamers for often carrying bleeding-edge patches and other experimental work prior to being mainlined. But over two months ago, Wine-Staging went silent without any further updates. A few days ago the original maintainers announced they parted ways with the work due to lack of time and would not be issuing any new releases. Now there are new developers taking over...

  • SUNY math professor makes the case for free and open educational resources
    The open educational resources (OER) movement has been gaining momentum over the past few years, as educators—from kindergarten classes to graduate schools—turn to free and open source educational content to counter the high cost of textbooks. Over the past year, the pace has accelerated. In 2017, OERs were a featured topic at the high-profile SXSW EDU Conference and Festival. Also last year, New York State generated a lot of excitement when it made an $8 million investment in developing OERs, with the goal of lowering the costs of college education in the state. David Usinski, a math and computer science professor and assistant chair of developmental education at the State University of New York's Erie Community College, is an advocate of OER content in the classroom. Before he joined SUNY Erie's staff in 2007, he spent a few years working for the Erie County public school system as a technology staff developer, training teachers how to infuse technology into the classroom.

Mozilla: Wireless Innovation for a Networked Society, New AirMozilla Audience Demo, Firefox Telemetry

  • Net Neutrality, NSF and Mozilla's WINS Challenge Winners, openSUSE Updates and More
    The National Science Foundation and Mozilla recently announced the first round of winners from their Wireless Innovation for a Networked Society (WINS) challenges—$2 million in prizes for "big ideas to connect the unconnected across the US". According to the press release, the winners "are building mesh networks, solar-powered Wi-Fi, and network infrastructure that fits inside a single backpack" and that the common denominator for all of them is "they're affordable, scalable, open-source and secure."
  • New AirMozilla Audience Demo
    The legacy AirMozilla platform will be decommissioned later this year. The reasons for the change are multiple; however, the urgency of the change is driven by deprecated support of both the complex back-end infrastructure by IT and the user interface by Firefox engineering teams in 2016. Additional reasons include a complex user workflow resulting in a poor user experience, no self-service model, poor usability metrics and a lack of integrated, required features.

All the great games tend to have a horribly steep learning curve, and all the simple games seem to involve crushing candy. Thankfully, there are a few games like Tales of Maj'Eyal that are complex but with a really easy learning curve.

Currently we have a problem in that tests are failing on 32-bit builds, and haven't had a chance to investigate the root cause. Hopefully we can add 32-bit jobs to the CI pipeline to catch this breakage as soon as possible.
