Lustre

Lustre

Lustre is the premier HPC parallel file system. It was originally an open source project which Sun Microsystems bought and when the Oracle aquisition occurred it seems that Oracle failed to run with it.

This was written in 2011; I looked it in 2018 when one of the links failed. Frankly I wondered if it was still in use or had been replaced by newer technologies, but as Wikipedia reports, it’s still going strong.

Here are my notes …

My 1st Apple Mac

My 1st Apple Mac

I bought a Mac Book Pro last week. 10th August 2009. I’ll probably write up some notes about how I get it to do a job of work. The first set of notes I need were the HTML editor. despite having already installed Open Office, which has an editor. This page is demised.

Configuring NTP

Configuring NTP

I want to configure NTP on this box, i.e. the Cobalt Qube as its losing time. Badly. This was written in 2011 or earlier, and should probably therefore not be used any more.

Municipal WiFi

In Jan 2012, the Telegraph ran a story on how Westminster and Kensington & Chelsea boroughs have agreed with O2 to build the world’s biggest free wifi network, this is mirrored at this thread at South East Central.

  • Municipal Urban WiFi at Wikipedia, includes a list of Cities with fee Citywide WiFi, in the UK, Bristol and Norwich. (Liverpool has a paid service and the funding status for Newcastle in County Down is unstated.)

San Francisco

San Francisco famously experimented with free city wide WiFi. It was started with quite a splash and I was visiting it on a frequent basis. It seems they have suspended municipal investment in the programme in 2007 and invest in more directed programme to resolve the digital divide.

Python

Python

I returned to Python in Oct 2010.

I have two problems to solve,

  1. converting my bliki to wordpress, (I never used Python for this)
  2. scripting for KDB & Hadoop

This article contains notes started in 2011, I did not make this an omnibus entry and it is very sketchy, covering file I/O, date & time, dictionaries vs. lists and PYTHONPATH.

Introduction

This was the web platform for Vanessa Garlick and Liz Gorman’s final year undergraduate project.

WordPress

WordPress gives us most of what we need, most importantly identity and authentication functionality. The one thing we are obviously missing is a voting solution.

I have found two,

  • Post Voting, this is their web site, it is available via the ‘install themes’ page.
  • Vote it Up, this is on the wordpress site.

We want to vote on Posts aka Places, Proposals and Comments. This means that we need to distinguish between comments and proposals. This may require using templates to force the use of pictures. a ‘Proposal’ tag and forcing the inclusion of the voting panel. The installation of votes into a theme, may involve editing the .php files. WordPress document ‘the Loop’ on the codex, which needs to be understood. The voting themes give us a way of reporting the votes.

Domain Name

I ordered this domain name, but got the web interface wrong. It placed the domain in a separate commercial package. I rang ‘one and one’ who talked me through the transfer. The support call id is 245322465. Thanks.

Header CSS

I added an 8px margin top to the header logo.
