New Qemu and VirtualBox docs for Linux

Hi all,

As part of my DIY Linux push, I've completed documents on running and
modifying Linux distros on Qemu and VirtualBox. There are many
advantages, including convenience and speed (on hardware with hardware
VM assist), and not collecting a vast pile of labeled hard disks for
the various experiments.

Here are the articles:

* http://troubleshooters.com/linux/diy/qemu.htm

I hope you enjoy them.

Debian mirror problem

I am trying to do an apt-get update on my Debian system and I am getting 
the following error:
E: Release file for 
http://debian.co.il/debian/dists/jessie-updates/InRelease is expired 
(invalid since 19h 6min 28s). Updates for this repository will not be 
applied.

I could change which mirror I use but is there someone on the list who 
can bring this to the attention of the right person to get it fixed?

Thanks,

Memory pool interface design

I'm writing a small C library, that I want to open source.

I want them to be usable for embedded environment, where memory allocation must be controlled.

Hence, I abstracted away calls to malloc/realloc, and replaced them with

struct mem_pool {
    void *(*allloc)(void *mem_pool, void *prev_ptr, int size);
};

User would implement

struct my_mem_pool {
    struct mem_pool pool;
    ...
};

struct my_mem_pool pool = { { my_alloc_func }, ...);

I've had to design question I'm interested with:

1) Should I support both malloc and realloc?

I think the performance benefits of supporting malloc instead of realloc(NULL) are negligible, and not worth complicating the interface.

2) Should the memory pool be allowed to fail?

In typical Linux system, where memory overcommit is allowed, checking malloc return value provides little benefit. But is it the same for embedded system?

My feeling is, embedded system should predict the memory usage for each input size, and avoid processing input which is too large.

For example, stack overflow error can never be handled, and one is expected to calculate the longest stack length for any input and make sure he wouldn't overflow.

So I think it's still reasonable never to report allocation failure, and to expect the memory allocator to raise the relevant abort/panic/exception in such a case.

But I'll be happy to hear other considerations I missed.

Thanks,

Creative Commons
Shlomi,

More than two-thirds of the Commons exists on content platforms
like Flickr, YouTube, Vimeo, Soundcloud, and Wikipedia. The main
way people share with Creative Commons is by using the platforms
they already know and love, so working with them is vital.

The SpaceX image linked below and over 300,000 other images in
the public domain wouldn't be freely available if it wasn't for
CC.

<https://donate.creativecommons.org/sites/all/modules/civicrm/extern/url.php?u=3988&qid=1382504>

To meet our strategic goal of growing the Commons, we must have
the resources to continue developing our relationships with
content platforms. Will you help fund this crucial work by
making a $25 or more contribution to our $50,000 fundraising
drive?

<https://donate.creativecommons.org/sites/all/modules/civicrm/extern/url.php?u=3986&qid=1382504>

Last year, CC had no resources dedicated to working with content
platforms. This year, we've begun to change that, and are
already seeing results. Just last week, the popular writing
platform Medium added the CC license suite, and in April Flickr
added CC0 and the Public Domain Mark -- their first major update
to CC licensing since they first adopted the licenses.

We saw the benefits almost instantly: in the first two weeks
after Flickr added CC0, over 130,000 new images were added,
including all of the spectacular images from SpaceX.

Across the Commons, we need to update our tools and
technology. We want to support unique licensing IDs to allow
content analytics; improve discovery and curation through better
search; and drive more collaboration and contribution to the
global photography archive through our mobile app beta, The
List.

Those are just a few of the exciting projects we're working on,
but our ability to continue depends on raising the funds
necessary to support our work.

Help us grow the Commons. Ensure Creative Commons integration on
platforms and the development of new tools to make CC licenses
easier and more useful to creators and re-mixers by making a
contribution today!

Thank you for your continued support.

TV tuner or video capture card recommendation

I have a VERY old no-name PCI TV tuner which has started to cause
problems (choppy video and no sound). Until recently it worked fine
and I could watch TV using TVtime or XawTV. I honestly don't know if
the problem is software (maybe caused by an upgrade?) or hardware (a bad
cable or connection or the card itself). But because it's so old, it's
probably not worth saving.

There are lots of articles on the net about hardware, drivers,
installation, what works or doesn't, etc. But I'm looking for firsthand
experience. For example, I've seen various articles about EasyCap or
EZCap working/not working. I do know that there are several similar
pieces of hardware using different chipsets, so it's hard to depend on
these articles. In fact, about a year ago I bought a card on eBay but
had no luck getting it to work.

My needs are really simple:
1 - USB connection
2 - can capture analog video and audio from a YES "MEMIR"
3 - works on Mageia and/or Raspberry PI Raspbian
4 - preferably work with TVtime, but any other workable software is OK

Accessing / Controling ProvisionISR DVR from Linux

Hi all,

A friend's coffee shop with a ProvisionISR DVR system. His main machine is a laptop running Ubuntu 14.04. 

He wants to access the DVR management through the browser, but when trying it claims it needs to install an ActiveX (yuk!) to run, and it has no support for Firefox / Google Chrome etc. (even under Windows)...

Any of you has any experience / ideas ?

Thanks!

Amichai

http://httpredir.debian.org/debian, do we use jessie-backports or jessie/backports?

When using the Debian apt system for updating packages, and when using
http://httpredir.debian.org/debian, do we use jessie-backports or
jessie/backports
Similarly - jessie-updates or jessie/updates?

The reason for my question:
When updating in aptitude, I sometimes got errors for some of the above.
Yet a Google search in Debian documentation did not give me a clear-cut
answer.

Easy to use hex editor?

Hi,

I have a DOS program I need to modify. I need to be able to load an DOS 
EXE file, and hopefully using a gui, search for ascii text and 8 byte 
floating point numbers in INTEL format and modify them. Then when I 
write the file it still needs to be be executable.

If it has a patch mode, where I can compare the patched version to the 
original and get a diff type output, I would really be happy.

I had a great one on my MAC, but I no longer have the MAC and would 
prefer to do it on a Linux system.

TIA for any suggestions.

Geoff.
