i have always wanted to give linux a go and figure a live cd is the way to go. i have a LG 4120B dvd-ram drive and was wondering if it would be possible to create a live disc using dvd-ram and if it would be possible to save any settings/changes i make onto the disc instead of using a harddrive.

It should be possible. Unfortunately not without knowing quite a lot about Linux first. Most Linux Live CDs will let you save your data to a USB key though. You probably wouldn't want to live with Linux on a CD or DVD very long anyway - as although it is an excellent demo - it is still just a demo. Performance won't be anything near what it would be if you had it installed for real.

Live CDs are good for fixing things (even with MS windows) and for impressing people.

Beyond this I'm not so sure how useful it would be for longer term use.

Someone might know of a DVD version of Knoppix you could use though. I'm sure I've heard of it. But making one yourself without having had any prior Linux experience? Probably not doable I'm afraid.

It sounds very possible.

I know that various LiveCD distros support either saving certain settings (or the whole /home partition) on devices such as memory sticks. It should be possible to have the DVD partitioned with the "Live" part in a partition, and the "/home" part as an extra partition.

I say this not knowing for a fact if a DVD-RAM can be partitioned into separate partitions. :unsure:

Well it may be possible. The question is could a relative novice do it? I am by most standards no Linux novice and even I think I would find it a long and complex process. The small and most immediate issue I envisage is that you would need to build an entire distribution from scratch in order to support this kind of functionality.

So from knowing nothing to building a whole new Linux distro in exactly zero steps is really what would be needed here. So perhaps the question should be rephrased, from is it possible to is it feesible?

The answer I think is a) yes it is possible but b) I doubt it's practical.

Sorry I can't give a more positive answer.

But why work so hard when there are viable solutions already in existance?

Are DVD-RAM discs block devices? If so, are they partitionable? If not...how would you partition it? Which leads to another question...why would you need to partition it in the first place? How many times can a DVD-RAM disc be written/rewritten to?

If you can produce a DVD-RAM live cd then you are *definitely* not a newbie to linux.

    • Google Chrome is killing all uBlock Origin bypasses, Microsoft Edge, Opera to follow

      Same for me. I find Adguard in general just OK. Ublock Orgin Lite works and works well. I use it on Chrome, Edge, and Safari on MacOS and iPadOS/iOS.

      I do not use the AdGuard extension. I have uninstalled both the uBlock and Stylus extensions, as well as the Tampermonkey extension, since I began using AdGuard for Windows 7 months ago. It does not use any extension APIs, it modifies traffic system wide using a local proxy. AdGuard performs all the functions of uBlock, as well as additional features such as HTTPS filtering, cosmetic (user scripts and user styles), as well as DNS. It works with any browser and application. I don't understand why you consider the desktop program to be useless...

      Should Google be forced to stop promoting Chrome over other browsers? Google pushes Chrome to anyone visiting its website using browsers other than Chrome.
    • Save 31% on Samsung T7 Portable SSD

      By TarasBuria · Posted

      Save 31% on Samsung T7 Portable SSD by Taras Buria During the ongoing memory crisis, where RAM and storage get extremely expensive, it is hard to find a good deal on an internal or portable SSD. While we are far away from 2024 prices, Samsung is currently offering a big discount on its 1TB T7 Portable SSD, saving you 31% or $85. The discount applies to the 1TB variant, which, although not record-breaking, is still plenty for all sorts of data. The drive uses a USB-C port for universal compatibility and high-speed data transfer of up to 1,050 megabytes per second. Samsung claims this drive is nearly ten times faster than a conventional hard drive, plus you get all the benefits of solid-state memory, such as better drop and shock resistance. There is also the ability to password-protect the drive, and you get extra peace of mind with a limited three-year warranty. The Samsung T7 Portable SSD works with all modern computers and tablets, including iPhones, iPads, Android smartphones, and more. And thanks to the two bundled USB cables (Type-C and Type-A), you can use the T7 even with devices that lack USB Type-C ports. The T7 Portable is available in three colors and four storage configurations, but unfortunately, only the 1TB Titan Gray is discounted: 1TB Samsung T7 Portable SSD - $189.98 | 31% off on Amazon This Amazon deal is US-specific and not available in other regions unless specified.

      Plenty of nations have risen from the ashes of war and today they have high standards of living. Maybe the problem is that your government is run by corrupt and power hungry terrorist organizations that keep the country in the **** because all they care about is filling up their pockets and maintaining their power instead of actually managing the country for the benefit of everyone. Just ask Russians, North Koreans, Iranians, Cubans, Venezuelans and Nicaraguans, etc.
