Oracle Versus PostgresQL
by Lawrence D'Oliveiro 21 Mar '16

21 Mar '16

Looks like Russia’s Government departments are looking to move to PostgresQL instead of Oracle. In response, Oracle has released a document trying to point out all the problems with PostgresQL <http://www.theregister.co.uk/2016/03/21/oracle_fights_russian_software_poli…>. First they ignore you, then they laugh at you, then they fight you...

How to maintain my connection to squeeze
by Chris O'Halloran 12 Mar '16

12 Mar '16

Hi all, I have a server at work that is hacked and customized to bits to keep a wiki going using mediawiki [1] software including node.js [1a] binaries. It was a turneky [2] appliance based on Debian 6 or squeeze. It's work very well these past 6 or 7 years. It also runs a ruby on rails app clockingit.[3] I've installed the anaconda python distribution [4] on it and that is running fine. It was the only way to get python 3.4 running nicely with notebooks. A thing I've been tinkering with lately is the latex circuit package circuitikz [5] for my making nice circuit diagrams and another bit of ipython magics [6] allows you to insert these into your ipython notebooks. I know this keeps putting off the inevitable but I'd rather procrastinate further than rebuild the server. It seems squeeze has experienced some sort of migration to an LTS release even though officially it's not longer supported. The point is, I'd like to sudo apt-get install texlive-science but say it will have problems chris@wiki apt/sources.list.d$ sudo apt-get install texlive-science Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: texlive-science : Depends: python2.7 but it is not going to be installed Depends: texlive-base (>= 2015) but it is not going to be installed Depends: texlive-latex-base (>= 2015) but it is not going to be installed Depends: tex-common (>= 6) but 2.08.1 is to be installed Depends: texlive-latex-recommended (>= 2015) but it is not going to be installed Depends: texlive-binaries (>= 2015.20160222.37495-1) but 2009-8 is to be installed E: Broken packages when I do sudo apt-get update Err http://cdn.debian.net squeeze/main amd64 Packages 404 Not Found [IP: 180.214.94.18 80] Err http://cdn.debian.net squeeze/contrib amd64 Packages 404 Not Found [IP: 180.214.94.18 80] Err http://cdn.debian.net squeeze/non-free amd64 Packages 404 Not Found [IP: 128.61.240.89 80] Fetched 39.3 kB in 7s (5257 B/s) W: There is no public key available for the following key IDs: 7638D0442B90D010 W: Failed to fetch http://cdn.debian.net/debian/dists/squeeze/main/binary-amd64/Packages.gz 404 Not Found [IP: 180.214.94.18 80] W: Failed to fetch http://cdn.debian.net/debian/dists/squeeze/contrib/binary-amd64/Packages.gz 404 Not Found [IP: 180.214.94.18 80] W: Failed to fetch http://cdn.debian.net/debian/dists/squeeze/non-free/binary-amd64/Packages.gz 404 Not Found [IP: 128.61.240.89 80] So is seems I need to update the squeeze sources to still access the old repos. I'm nervous about upgrading because of all the customisations and don't wish to break things. Any clues on how I have have my server still able to download old packages.

Former Microsoft CEO No Longer Negatively Attacks Linux
by Lawrence D'Oliveiro 11 Mar '16

11 Mar '16

Interview with Steve Ballmer linked from <http://phoronix.com/scan.php?page=news_item&px=Ballmer-Linux-Cancer-Free>: Fifteen years after calling the open-source operating system Linux a "cancer," former Microsoft Corp (MSFT.O) Chief Executive Steve Ballmer has softened his position. Speaking on Wednesday night at a dinner hosted by Fortune magazine, Ballmer said the position was right for the time, but the threat from Linux was now "in the rearview mirror." Which is why Microsoft is spending more effort than ever on Linux, no doubt...

Microsoft SQL Server For Linux?
by Lawrence D'Oliveiro 07 Mar '16

07 Mar '16

From <http://arstechnica.com/information-technology/2016/03/sql-server-for-linux-…>: The announcement implies [one of] two things. Either there is a large number of Linux-using corporations out there that are desperate for SQL Server's feature set (as opposed to open source databases such as PostgreSQL, MySQL, or MaxDB, or the proprietary ones such as IBM's DB2 and, of course, Oracle's Oracle), or there is a large number of SQL Server-using organizations out there that are keen to ditch the cost of their Windows licenses but happy to continue to pay for their SQL Server licenses. Neither seems obvious to us. Nor to me...

Raspberry Pi 3
by William Mckee 02 Mar '16

02 Mar '16

Hello, Raspberry Pi 3 was just released. The highlights of the model: Raspberry Pi 3 - Model B Technical Specification Broadcom BCM2387 chipset 1.2GHz Quad-Core ARM Cortex-A53 802.11 bgn Wireless LAN and Bluetooth 4.1 (Bluetooth Classic and LE) 1GB RAM 64 Bit CPU I think I am most excited about the 64 Bit CPU. What's also amazing is they have kept the same price as the Raspberry Pi 2 - 35 pounds. I'm happy with my Raspberry Pi 2 setup but keen to pick one of these up (still can't get a zero). Blog post: https://www.raspberrypi.org/blog/raspberry-pi-3-on-sale/ cheers, William.

LibreSSL Unaffected By DROWN
by Peter Reutemann 02 Mar '16

02 Mar '16

"The OpenBSD people forked and heavily cleaned up OpenSSL to create LibreSSL due to dissatisfaction with the maintainance of OpenSSL, culminating in the heartbleed bug. The emphasis has been on cleaning up the code and improving security, which includes removing things such as SSL2 which has fundamental security flaws. As a result, LibreSSL is not affected by the DROWN bug. LibreSSL is largely compatible with OpenSSL. The main exceptions are in the cases where programs use insecure functions removed from libreSSL, or require bug compatiblity with OpenSSL." -- source: http://it.slashdot.org/story/16/03/02/1620221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A Third of All HTTPS Websites Vulnerable To DROWN Attack
by Peter Reutemann 01 Mar '16

01 Mar '16

"The OpenSSL project has released versions 1.0.2g and 1.0.1s to address a high severity security issue known as the DROWN attack (CVE-2016-0800) which allows attackers to break HTTPS and steal encrypted information. In layman terms, the attack uses an improperly patched issue (from 1998) in SSL to attack websites using the more modern TLS protocol. Servers where admins use SSL and TLS are in danger. Additionally, servers where only TLS is used, but the admins are sharing the same certificate for other servers where they have SSL, are also vulnerable, since the attack targets RSA, employed in both SSL and TLS. The entire attack is also easy to carry out, costing only $440 on Amazon EC2." -- source: http://it.slashdot.org/story/16/03/01/1743237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

OpenShot 2.0 Beta Is Out
by Lawrence D'Oliveiro 29 Feb '16

29 Feb '16

Initial verdict on the results of the crowd-funded development: “The real winners here are Linux users who now have an editor that's on par with Apple's iMovie (even more powerful than recent versions of iMovie) and bears considerable resemblance to the industry-standard Final Cut Pro.” <http://www.theregister.co.uk/2016/02/29/openshot_2_review/>
