hpr1491 :: Heartbleed

Hosted by laindir on 2014-04-21.
Listen in ogg, spx, or mp3 format. Series: Privacy and Security | Comments (0)

The "Heartbleed" vulnerability in OpenSSL (CVE-2014-0160) is a bounds checking error in the heartbeat implementation that could return up to 64K of private data to the client. This can lead to server certificate private keys, session cookies, clear text passwords, or other sensitive data being leaked from the server to the client. This vulnerability exists in OpenSSL versions 1.0.1 through 1.0.1f and 1.0.2 beta.

It is important for server administrators to update OpenSSL as soon as possible and take steps to secure any private data which may have been leaked. This may include updating server certificates and revoking certificates that may have been compromised.

Users should ensure that web sites they use have been secured and should update passwords or other authentication information.

hpr1488 :: What's on My Podcatcher

Hosted by Keith Murray on 2014-04-16.
Listen in ogg, spx, or mp3 format. Comments (1)

After listening to Ahuka describe his favourite podcasts on HPR1479 and HPR1482 I was surprised to see how few of the shows we listen to overlap. There are so many podcasts out there it's always good to be able to get recommendations. I present to you my list of 30 podcasts (I had to cull the list down a bit).

hpr1486 :: Linux Luddites Episode 11 - Interview with Rob Landley

As stated on the HPR Contribution page

We will continue to promote new podcasts and other creative commons material but due to a lack of slots, we are only releasing material created exclusively for HPR. If there is a piece of creative commons content that you would like to promote, then feel free to record a regular show where you introduce the content and explain why it is important, providing links to where we can get more information.

Today I am doing just that. As a member of the HPR community, I would like to bring the podcast LINUX LUDDITES with the tag line "Not all change is progress". Taking their name from "Linux" the an operating system kernel by Linus Torvalds, and "Luddites" from the 19th-century English textile artisans who protested against newly developed labour-saving machinery.

I am submitting Episode 11 as it includes a fascinating interview with Rob Landley, former maintainer of BusyBox and covers among other things his experiences of GPL enforcement. For complete episode show notes see

If this podcast is not in your feed, you would do very well to add it.

If there is a show is new to the scene, ie not on the, then contact us about it and also consider submitting an episode as a featured podcast.


hpr1485 :: 26 - LibreOffice Calc Cells

Hosted by Ahuka on 2014-04-11.
Listen in ogg, spx, or mp3 format. Series: LibreOffice | Comments (0)

LibreOffice Calc: Cells

All spreadsheets have the same basic structure, a table of rows and columns. Columns are headed up A, B, C, and so on. After Z, the next column is AA, then AB, AC, AD, and so on. The maximum number of columns is 1024. Rows are numbered 1,2,3 and so on, and the maximum number of rows is 1024*1024, or 1,048,576. At this time I am not aware of any plans to increase these numbers, though that could change if competitive pressures make it necessary.

Where a row and column intersect, there is a cell, which is given the address of the column followed by the row, e.g. A1, but never 1A. This is very useful since you can use the contents of a cell in a calculation by simply using the cell address. For example, to add the value of cell B4 to the value in cell C3 and store it, you would write “=B4+C3″ in the cell where you want to store the sum. Learning to use cell addresses is extremely important, so get in the habit of doing this at every opportunity.

Mailing List discussions

Policy decisions surrounding HPR are taken by the community as a whole. This discussion takes place on the Mail List which is open to all HPR listeners and contributors. The discussions are open and available on the Gmane archive.

Discussed this month was:

Backup Shows

In a discussion started by Dave Morris. Some felt that the content was getting stale, and keeping shows for 2 years or even 3 months was too long. Others felt that these shows were contributed with the purpose of been used in an emergency and therefore should be timeless.
Eventually it was left to each of the contributors that had shows in the backup queue to release them, or to set them as emergency shows. The website has been updated to reflect this change.


The next audiobook is Shaman Tales Book 1: South Coast by Nathan Lowell. It's available on
