Reddit: Can someone explain to me exactly what Linux is?

Sunday 21st of December 2014 11:15:14 AM

I am not exactly computer intuitive but looking to learn more about computers and computer programming. Is Linux simply the alternative to Windows and what are the advantages and disadvantages of having one or the other?

Is Linux supported by most laptops and if so, how do I go about making my computer run on a Linux Operating System? I wouldn't make the change until I am a lot more knowledgable about computers but I am simply interested in learning everything I can. I am a total noob so try to explain it in terms I would most likely understand. Thanks!

Reddit: I'm an idiot, please help

Sunday 21st of December 2014 08:48:25 AM

Hi everyone

I renamed ny /usr folder to /usr_old on my macbook air because I believed that /usr only stored linux loaded programs. I didn't realise that it actually ran my whole macbook.

So, I've made an ubuntu live usb and I can see my HD as 'Macintosh HD'... the problem is that it's read only so I can't rename /usr_old back to /usr. I've looked at ways of mounting it read-write but when I try something like 'sudo mount -o remount,rw /dev/sda2' I get 'mount: /media/ubuntu/Macintosh HD not mounted or bad option'

Please let me know if you need any more information to help me out. I'm quite desperate here as I'm writing a thesis at the moment (running out of time) and I can't really afford this hiccup.

EDIT: link to linux questions post http://www.reddit.com/r/linuxquestions/comments/2pyoig/im_an_idiot_please_help_me_remount_my_internal_hd/

EDIT: FIXED with the second comment from https://superuser.com/questions/84446/how-to-mount-a-hfs-partition-in-ubuntu-as-read-write

Thanks for everyone's help!

LXer: How to protect SSH server from brute force attacks using fail2ban

Sunday 21st of December 2014 08:05:07 AM
One common attack on SSH service is brute force attacks where a remote attacker indefinitely attempts to log in with different passwords. Fail2ban is an open-source intrusion prevention framework on Linux that monitors various system log files (e.g., /var/log/auth.log or /var/log/secure) and triggers various defensive actions upon detecting any suspicious activities. You can use fail2ban to defend against brute force password guessing attacks on an SSH server.

Reddit: I've always used bash. Is there a good reason to explore other shells?

Sunday 21st of December 2014 02:45:07 AM

I'm a pretty experienced bash user at this point. I use it all day on both OS X (on my desktop) and linux (on all the servers I manage), and have written dozens if not hundreds of bash scripts, some fairly complex, pushing the limits of what one would want to do with bash before switching to a more full featured language like Python or Perl. I have dug deep into the depths of tldp.org's bash programming guide, set obscure shell options, pulled backreferences out of regexes, written functions that return arrays, etc. While bash goes pretty deep, I feel like I've touched a lot of it.

But I've never actually touched another shell. Am I missing out?

I'm not a C programmer so I feel like the benefits of the csh family would be lost on me, but how about other options? zsh? fish?

I also feel like bash is the standard for somewhat arbitrary reasons... there are lots of weird inconsistencies in bash, and the fact that most of the original documentation is in the form of info pages, satan's own documentation format, is a major point against it too :)

Anyway, curious to know the thoughts of people who have (real) experience in other shells.

LXer: Top patent court shoots down Myriad gene testing patents

Saturday 20th of December 2014 09:11:56 PM
The US Patent and Trademark Office handed out patents on human genes for about 30 years, but genomic patents were blocked after a landmark Supreme Court ruling last year.The patent holder in that case, Myriad Genetics, had patented a test on the BRCA1 and BRCA2 genes. The test shows mutations that reveal which women are more susceptible to breast and ovarian cancer. The BRCA test is substantially cheaper in countries where it wasn't patented, such as Canada.After losing its case, Myriad didn't give up. Instead, it quickly filed a new round of lawsuits, trying to keep competitors like Ambry Genetics out of the business of BRCA testing. The new suits named different patents, which instead of simply claiming the gene itself, included "method" claims and also discussed the use of DNA "primers"—an entirely lab-made substance which Myriad lawyers said were still open to being patented.

Leaked videos, screenshots reveal an HTC One running Android Lollipop

No, you won’t get this gift in time for Christmas, but perhaps seeing an HTC One running Lollipop may make the wait slightly less painful. A batch of videos and screenshots show HTC’s flagship with the newest build of Android, though of course it’s merged with the Sense 6.0 user interface (the HTC One currently runs Sense 5.0). We got a small hint of how Lollipop looks on the One in November, but this leak lays out what the entire operating system makeover looks in clearer detail. Read more

The winning Linux kernel live patch: All of the above

Life's choices often amount to one of two options: Linux or Windows? Android or iOS? Kgraft or Kpatch? That last pair consists of the two major contenders for the technology Linux could use for live kernel patches. Now a winner is in, and it amounts to all of the above. According to a post on the official Linux kernel developer's mailing list, a kernel patching system that works with both Kgraft and Kpatch and uses "core functionality abstracted out of [those] already existing implementations" has been proposed as an addition to the Linux 3.20 kernel.
