Reddit: New computer for grandma — Raspberry Pi 3 or...?

Wednesday 13th of April 2016 02:09:31 PM

My grandmother's computer is a second-generation Mac Mini currently — the late 2005 1.5GHz G4 SuperDrive, bought when it was going out of style in 2006. Currently runs the last available OS X 10.5.

By now that computer is starting to show its age a tiny bit.... But actually it still almost works for the purpose.

I'm thinking it's time for something that can still get updates that are newer than 5 years ago. Ideally something inexpensive, silent, not particularly powerful, but with decent accessibility features (screen zoom etc is important).

So I figure this sounds like something that would be almost ideally suited to a raspberry Pi, running either raspbian or Ubuntu or kUbuntu. I don't wanna skimp on important things, so what I came up with:

-Raspberry Pi 3 -Samsung Evo+ 64G (these seem to be by far the fastest microSDs available for random write) -Anker 2 port 24W (power supplies really need some headroom for this usage, I've found) -random case & heat sink kit -hdmi to DVI cable -Anker 30cm USB power cable

The lot is about 100 euros, give or take.

Is there an even cheaper alternative that gets me a working system for less?

Conversely, are there alternatives where I can spend just a little more for significantly better functionality?

I've looked at odroid, bananapi, cubieboard, and beaglebones, but I remain to be convinced any of them are relevant to me.

Reddit: Diagnosing uninterruptable system hangs/wedges

Wednesday 13th of April 2016 12:37:45 PM

Folks, I've been doing sysops stuff for a couple years, and using Linux as a hobbyist for many years before that, but I've never really figured out how to diagnose the root of uninterruptable system wedges - I've always simply rebooted a system when this happens, skimmed the system logs & sar for anything obvious (almost never), and gone on with life.

I'm starting to be responsible for much larger systems and if a system wedges up and needs to be rebooted, it's likely that answers about the cause will be demanded.

Are there any resources you can send my way for learning to diagnose these sorts of hard system wedges?

Thanks!

ImageMagick Security Bug Puts Sites at Risk

  • Open Source ImageMagick Security Bug Puts Sites at Risk
    ImageMagick, an open source suite of tools for working with graphic images used by a large number of websites, has been found to contain a serious security vulnerability that puts sites using the software at risk for malicious code to be executed onsite. Security experts consider exploitation to be so easy they’re calling it “trivial,” and exploits are already circulating in the wild. The biggest risk is to sites that allows users to upload their own image files. Information about the vulnerability was made public Tuesday afternoon by Ryan Huber, a developer and security researcher, who wrote that he had little choice but to post about the exploit.
  • Huge number of sites imperiled by critical image-processing vulnerability
    A large number of websites are vulnerable to a simple attack that allows hackers to execute malicious code hidden inside booby-trapped images. The vulnerability resides in ImageMagick, a widely used image-processing library that's supported by PHP, Ruby, NodeJS, Python, and about a dozen other languages. Many social media and blogging sites, as well as a large number of content management systems, directly or indirectly rely on ImageMagick-based processing so they can resize images uploaded by end users.
  • Extreme photo-bombing: Bad ImageMagick bug puts countless websites at risk of hijacking
    A wildly popular software tool used by websites to process people's photos can be exploited to execute malicious code on servers and leak server-side files. Security bugs in the software are apparently being exploited in the wild right now to compromise at-risk systems. Patches to address the vulnerabilities are available in the latest source code – but are incomplete and have not been officially released, we're told.
