Reddit: Computer can't compile Linux kernel properly?

Sunday 7th of August 2016 04:35:11 AM

I was setting up this old laptop of mine with a Intel Pentiu M processor. It's been a few days now and for some reason, I couldn't getting a working custom kernel on it. The screen would go blank, caps lock and scroll lock starts blinking and I won't be able to see the error messages. I re-compiled it with vesa, found out that it couldn't locate init and was told to add 'init=' to my boot parameters. I did so and same error.

But just today, I decided to copy the '.config' and compile it on my i7 laptop to save time. And voila, after copying it over with the modules, the kernel works on the pentium laptop.

Does this laptop lack the capabilities to compile the Linux kernel?

Mentions: Linux Lite 3.0 | CPU doesn't support PAE | During compilation on the pentium, it would sometimes throw errors that can be fixed with a 'make clean'.

Reddit: Request for practice questions

Sunday 7th of August 2016 04:27:41 AM

Hi all,

Took my LFCS this morning and I'm not confident I did that well. I have a retake I can schedule, so I'll wait for my results before jumping the gun, but in the meantime I'd like to make a request.

Could members of the community come up with, or provide me a good resource for, sample questions that can help me test the practical knowledge I need to do well on these kinds of exams? I can't list specific question requests due to the confidentiality agreement, but the domains and competencies listed on the Linux Foundation Website definitely covers the topics that I was tested on earlier today.

What I'm hoping to find is just something simple, that directs me to do a task but doesn't hold my hand. So an appropriate question could be "create a user named blah, with password blah, and a default shell of blah."

The questions I struggled with most had to do with file manipulation, such as listing specific files in a directory, files with only a specific type of permission, etc. I also had no clue on what to do with LVM, and there were many questions related to archiving and backups, specifically dealing with bzip2, that threw me for a loop.

Any help is appreciated, and thanks in advance!

Reddit: Ubuntu 16.04 / Mint on a MacBook Pro retina?

Sunday 7th of August 2016 03:14:37 AM

Hello everyone! Totally new to the Linux world and am loving my adventures with it so far (VPS with Ubuntu 16.04 LTS is my current and only experience with Linux).

I currently have a Windows PC but will be purchasing a MacBook Pro for development purposes. I am looking to install Linux on it because I have heard that Apple is moving towards a singular user experience through mobile and desktop/ laptop which I am not a fan of.

So I am curious if this is still a possibility with their current driver and hardware situation?

Thanks!

TuxMachines: Security News

  • How Public Shame Might Force a Revolution in Computer Security

    The numbers are depressing. An estimated 700 million data records were stolen in 2015. But despite the billions spent on computer security, flaws that allow such attacks are fixed slowly. A June report found that financial companies, for example, take on average over five months to fix known online security vulnerabilities.

    “The security industry gets $75 billion every year to try to secure things, and what you get for that is everybody is hacked all the time,” said Jeremiah Grossman, chief of security strategy at SentinelOne, speaking at the Black Hat security conference in Las Vegas on Wednesday.

    Yet Grossman and some other veterans of the security industry have lately become more optimistic. They see a chance that companies will soon have much stronger financial incentives to invest in securing and maintaining software.

  • DefCon: How the Hacker Tracker Mobile App Stays Secure

    The DefCon hacker conference here at the Bally's and Paris Hotels is a massive affair with many rooms, events and workshops spread across multiple times and days. While there is a paper schedule, many hackers now rely on Hacker Tracker, which has become the de facto mobile app of the DefCon conference.

    The Hacker Tracker was developed by two volunteers, Whitney Champion, systems engineer at SPARC, and Seth Law, chief security officer at nVisium. Champion built the Android version of the app while Law built the iOS version.

    In a video interview at DefCon, Law provided details on how Hacker Tracker is built and the steps he and Champion have taken to keep it and hacker data secure.

TuxMachines: ACT calls on government to support open source software

Saturday 6th of August 2016 11:05:03 PM

It's fair to say that NZ Rise co-chair Don Christie and ACT leader David Seymour don't always see eye-to-eye.

But Mr Christie today found some common ground, backing Mr Seyour's call for the government to consider open source software.

The Epsom MP says the government to take a new approach in its software procurement policies, allowing substantial savings to the taxpayer.

“A substantial number of civil servants could generate the same output using open source software and open document formats, instead of proprietary software like Microsoft Office," he says.

TuxMachines: Open Source: Fuel Powering Innovation and Digital Transformation

Saturday 6th of August 2016 10:57:58 PM

Open Source continues to make an impact on both IT and software development.

Open source innovation has led to the development of new markets over ten times during the last twenty years, said David Senf, vice president at IDC Canada. The first major impact of Open Source was with the development of the Linux operating system. Next was the influence of the Apache web server, and then open source databases like MySQL came on the scene. After that, there has been a flood of open source software spanning many categories.

Open source products include development tools, web browsers, the Android operating system, Hadoop for big data, and tools like Jenkins, Chef and Puppet for devops. Products like OpenStack are also taking on the cloud. And, in fact, much of the cloud today runs on Linux. Senf said that “open source is the platform that big data is built on. Without Hadoop and Spark, we wouldn’t have big data.”

Reddit: I need a serious file compressor

Saturday 6th of August 2016 10:01:03 PM

I need to compress 1TB of RAW unprocessed photos. The thing is I have two external HDDs, 1TB each, synced to each other as backups of one another. I can't stop photographing just because I don't have storage space, and I can't afford to keep buying external HDDs because I need to buy 2 at a time and sync them so that if one fails, I still have my photos.

Another reason I don't wanna buy more external HDDs is because photography is a hobby for me and I'm a college student whose unemployed at the moment. (I'm job hunting)

So I need a serious compression software for Xubuntu. 7z doesn't compress much at all.

EDIT: I'm dual booting Xubuntu 16.04 and Windows 8.1 Home.

GNOME Control Center 3.22 to Update the Keyboard Settings, Improve Networking

The upcoming GNOME 3.22 desktop environment is still in the works, and a first Beta build was seeded to public beta testers last week, bringing multiple enhancements and new features to most of its core components and apps. While GNOME 3.22 Beta was announced on August 22, it appears that the maintainers of certain core packages needed a little more time to work on various improvements and polish their applications before they were suitable for public testing. And this is the case of GNOME Control Center, which was recently updated to version 3.21.90, which means 3.22 Beta. Read more
