An Ordinary User’s Adventures In Linux
by Lawrence D'Oliveiro 30 Sep '17

30 Sep '17

I helped an elderly friend set up his new PC yesterday. His previous machine, over a decade old, was running Windows XP. I had set up an Ubuntu dual-boot a few years back, and he liked playing the games. But then the Linux boot stopped working--there was a message to the effect “hd0 out of disk”, which sounded like a GRUB problem (“hd0” being a GRUB disk name, not a Linux disk name). I booted up SystemRescueCD, and found that disk space was ample. I did an fsck on the Linux volume, and found no filesystem problems. I ran a badblocks scan, and it reported several bad sectors, though oddly they only seemed to be in the Windows partition (if I interpreted the numbers correctly). Naturally I searched online, but the hits I found for that error message didn’t seem very helpful. Reinstalling GRUB didn’t help, so I concluded there were likely other hardware problems, so time for a new machine. He got an entry-level dual-core AMD box from PBTech--their own house build, in a CoolerMaster case--for well under a grand. Nothing fancy, but good enough for his needs--mainly Web browsing, e-mail, a little bit of word processing, and those games. The PBTech box came without an OS. He could have got Windows 10 for it, but considering he would be facing a learning curve coming from XP regardless, I suggested going 100% Linux for all his daily needs, to see if that would work. He could always spend the $160-odd extra on Windows later if need be. So I set it up with Linux Mint, since that seems to be everybody’s favourite :). He was already using Firefox on Windows, so moving all his Web bookmarks across was easy. The Mint install put an icon for Thunderbird on the desktop by default, so I decided to try that for e-mail. Getting his address book across from Outlook Express was fairly straightforward, once I figured out how to map the exported CSV field names correctly. The mail messages were slightly more fiddly, but I found this extension <https://addons.mozilla.org/en-US/thunderbird/addon/importexporttools/> which directly loads Microsoft’s .dbx files, and that seemed to work OK. Then he wanted to play CDs. When we put in an audio CD, it came up with options to run Banshee (media player) or Brasero (disc burner). The Banshee media player wouldn’t play the CD directly, it insisted on ripping it to the hard drive first. This was not really what he wanted. I had a look round, and found KsCD, which will indeed play audio CDs without trying to rip them to audio files first. As far as I know, this is the only GUI Linux app that can do so. So, day 1 ended on a reasonably successful note. He was already noticing how much faster the new machine was. So we’ll see how it goes from here...

The End Of GCJ?
by Lawrence D'Oliveiro 16 Nov '16

16 Nov '16

GCJ, the GNU Compiler for Java, has been languishing for some time, and may be about to be put out of its misery. Unlike the Sun/Oracle compiler, GCJ can compile to native machine code (thanks to the common GCC infrastructure), it is not restricted to some intermediate byte code. It originated before Sun open-sourced Java, and I guess a lot of the need for it went away when OpenJDK appeared. <http://phoronix.com/scan.php?page=news_item&px=GCC-Patch-To-Drop-GCJ>

When Is JSON Not JSON?
by Lawrence D'Oliveiro 01 Nov '16

01 Nov '16

I thought JSON was a nice, simple, straightforward spec. Turns out different implementations interpret some things just that little bit differently enough to lead to headaches. That means security headaches <http://www.theregister.co.uk/2016/11/01/json_parsers_tested/> ...

Fwd: Domain Name Commission introduces provisional address masking option
by Simon Green 01 Nov '16

01 Nov '16

Not strictly Linux / Open Source related, but thought I'd share this in relation to making your .nz whois address information private if you are an individual. Most interesting is "Any mail sent to the masked address displayed on the WHOIS will be forwarded to the address on the Register, by DNCL.". This means you could give anyone or a company your masked address if you don't want to give out your real postal address. -- Simon -------- Forwarded Message -------- Subject: Domain Name Commission introduces provisional address masking option Date: Tue, 1 Nov 2016 10:36:51 +1300 Media release – 1 November 2016 The Domain Name Commission (DNCL) has today introduced a free provisional address masking option where any individual (natural person) .nz domain name holder can ask that their contact address be masked from public display in the WHOIS (domain search tool). Just what information should be displayed when a WHOIS search is done on a .nz domain name is the subject of a major review. Throughout the review, DNCL has become aware that some individual registrants are concerned for privacy and personal safety reasons about having their contact address publicly displayed. The provisional address masking option has been introduced to help alleviate these concerns while DNCL carries on with its WHOIS review. Those wanting to take advantage of the option will have his or her contact address masked with a unique reference code and DNCL’s P.O. Box address. Domain Name Commissioner Debbie Monahan says DNCL is currently running a public consultation – asking for the community’s feedback on two policy options for withholding some information in the WHOIS, including contact address information. “In the meantime,” she says, “the address masking option announced today is intended to allay any personal safety concerns around public display of address information while we finish up our review and implement any permanent policy changes – expected to be later in 2017.” With the provisional address masking option, any individual registrant can ask that their contact address is masked from display in the .nz WHOIS. This doesn’t change their contact address information recorded on the .nz Register; it just means that information can’t be seen when someone does a WHOIS search on their domain name. Any mail sent to the masked address displayed on the WHOIS will be forwarded to the address on the Register, by DNCL. Importantly, says Monahan, the masking option is open to any individual registrant who is concerned for whatever reason about having their contact address publicly visible. She encourages all individual registrants to make use of it if they feel the need. The address masking is a straightforward process, but can only be effected by DNCL. It works by having individual registrants email DNCL from their email address on record. The DNCL office will then run some basic verification checks before applying the masking. The option is not available to businesses or organisations. Visit dnc.org.nz/pamo <https://www.dnc.org.nz/pamo> to find out more about DNCL’s provisional address masking option.

UDOO
by rowan schischka 01 Nov '16

01 Nov '16

"It is based on Quad Core 64-bit new-generation x86 processors made by Intel®, designed for the PC domain. Prodigious processors concentrated in 14 nm, with an amount of energy consumption of 5 or 6 Watt." http://www.udoo.org/udoo-x86/ If you're thinking of getting a raspberry pi this month, have a look at UDOO. x86 with a bunch of impressive specs shipping in december. For those of us conscious of using linux in low energy computing its still not as cheap as the m-ITX Asus N3050I-C. -- Kind Regards Rowan Schischka +64226719711

Is Lenovo Blocking Linux Installs?
by Lawrence D'Oliveiro 28 Oct '16

28 Oct '16

You may have heard that the BIOS on Lenovo’s Yoga 900 laptops has not been allowing the installation of non-Windows OSes (like Linux). After being on the receiving end of much opprobrium, Lenovo has finally released a BIOS update to fix this <http://www.theregister.co.uk/2016/10/28/lenovo_downward_dogs_with_yoga_bios…>. As usual, there are the suggestions that this was a deliberate deal done with Microsoft to shut out competitors to Windows. But then again, Hanlon’s Razor usually applies: “never ascribe to malice that which can be adequately explained by stupidity”. (See the reader comments on the above article for more examples of such stupidity.) Matthew Garrett has some more analysis <http://mjg59.dreamwidth.org/44694.html> on the specific issue that was stopping Linux installs: the hard drive controller is locked in “RAID” mode rather than “AHCI” mode. “AHCI” allows normal Linux drivers to work, while “RAID” mode requires special hardware-specific drivers. These special drivers don’t actually have to offer any RAID functionality; think of the “RAID” setting as just a way to block the generic drivers from taking control of the hardware. Garrett’s article has some discussion of why this might even be necessary: in this case, it may have to do with implementing proper power management.

Quirky 8.1 from Barry Kauler of Puppy who likes R Pi it seems
by Ian Young 26 Oct '16

26 Oct '16

Go Bazza!!! somewhere on the net Quirky Xerus 8.1 All Quirkies prior to 8.1 have been built for x86 and x86_64 PCs. Version 8.1 is the first to be built for the ARM platform, specifically the Raspberry Pi2 and Pi3. Note that Quirky will not work on a Pi1. It is expected a build for the Odroid XU4 is coming soon. The functionality is much as you have come to expect with a Puppy-derivative -- you get "the kitchen sink" in a very small package. That is, an application for just about everything and utilities to setup and configure just about anything. A difference though, with the Raspberry Pi build, is that it includes LibreOffice and Inkscape, whereas Puppy-derivatives usually have light-weight choices, such as Gnumeric, Abiword and InkscapeLite. This decision was made so as to provide the same functionality out-of-the-box as Raspbian, and in fact a whole lot more. This has resulted in a somewhat larger build than usual, a download file of 360MB. However, compare that with Raspbian at 1.3GB, and Quirky is still relatively small. As this is the very first release of Quirky for the Pi, it may have some issues, though we have been testing at the Puppy Forum and have fixed, hopefully, most of them. Some outstanding issues are:

Another Raspberry ? Contender

on indiegogo i like the picture half way down of the VoCore2 inside an ethernet wall socket. seems like a perfect disposable spy tool. It wont hurt raspberry pi sales as it does not have video, its just a really small networking toy https://www.indiegogo.com/projects/vocore2-4-coin-sized-linux-computer-with… -- Kind Regards Rowan Schischka

Another Raspberry π Contender
by Lawrence D'Oliveiro 25 Oct '16

25 Oct '16

Came across this mention <https://www.techdirt.com/articles/20161024/09194835873/daily-deal-vocore2-m…> of the “VoCore2 Mini Linux Computer”. Usually, rivals to the Raspberry π fall down either in price (e.g. anything Intel-based) or in features (e.g. the BBC Micro:Bit). But this seems, at first sight, to hold its own in both areas. And it goes one better than the π in terms of size. Thoughts?

>NiceGear does sell an uninterruptilble power supply hat for the Pi. The problem with that UPS is its $50, 300mah, and supplies 15minutes of power. I want to run a pi on solar power 24/7. Iv run the pi3, idle, on my 20.000mAh for about two days; which means ill probably need a 10,000mAh battery. I say about two days because i did not run the battery flat, just down to one bar. I can't use the pack I have without re-wiring it because i need to press a physical button to switch it on and it won't supply power while its charging. Do you think a realtime clock would be necessary considering i can get time off a server? I'm also considering repurposing my old phone because it already has a battery, but it doesn't have much ram and is also running a very old unsupported android. -- Kind Regards Rowan Schischka +64226719711
