I've been playing Half-Life recently, something to which I've looked forward for quite some time. I did get it playing under Wine years ago, but I thought I only got a little ways. I'm stuck In the Rails right now, but I remember this level.

Getting Squid3 on Debian 6.x to work with Active Directory, Security Groups and Websense

Filed under
Linux

I’ve had a need to get a local squid proxy to perform local filtering based on AD Security groups because it’s not something websense can do. I found this wonderful howtofoge guide online and Used it to setup the base system. This howto is a work in progress as the next stage is to get it working with DansGuardian or SquidGuard.

Enabling Dual Factor Authentication on Linux SSH logins..

Filed under
Linux

A couple of weeks ago I wrote a post on using a Chromebook to develop on a cloud platform. Its based on a Digital Ocean remote server and like most people who wish to attach to the command line interface on a remote server I use SSH. It’s an encrypted connection over the network/internet from end to end. However being a cloud server I was wondering if it was possible to secure this a little bit more?

A chat with a friend on the way into work provided me with a solution.

The solution is Two Factor authentication a system beased on a simple premise, something you know (the SSH password in this case) and something you have (your mobile phone in this case, but it could be a secure token) which will deliver a random number.

Using a Chromebook to develop in the cloud…

Filed under
Linux

Being a few months in with my Acer C7 Chromebook as my only laptop i’ve very pleased with what it does, I do have the Crouton Ubuntu chroot installed and upgraded the device to 16Gb of Ram, however there is one core thing I miss with this setup. VMWare/Virtualbox. I find i’m often building virtual machines, usually Ubuntu to test bsh scripts or build LAMP Environments to test some PHP out with. That isn’t something i’m able to do even on the CHROOT Ubuntu environment.

All however is not lost, and i’ve found a way to get round this..

They say a week in politics is a long time, well a year in the mobile phone industry is an eternity and what huge changes the industry is going through. A year ago the roost was ruled by Apple and Google, 3G was the fastest we can go and handsets were finding a stock size at 4.5″.. The world however of the mobile device is now a very different place and very much in a positive state of change..

Casual Programming and Linux Screen-Recorders

Filed under
Linux

After being retired (for four years) from teaching high school Computer Science, I decided to get back into programming again. I once taught a beginning programming class using the Ruby language, and I thought that would be a good way to get back into programming. So, I decided I needed a “Ruby refresher”, and I wanted to learn more about that language than I taught in the classroom.

GNOME: Belated GUADEC Report, "Is GNOME Just Lazy?"

  • Alberto Ruiz: GUADEC 2017: GNOME’s Renaissance
    This is a blog post I kept as a draft right after GUADEC to reflect on it and the GNOME project but failed to finish and publish until now. Forgive any outdated information though I think the post is mostly relevant still. I’m on my train back to London from Manchester, where I just spent 7 amazing days with my fellow GNOME community members. Props to the local team for an amazing organization, everything went smoothly and people seemed extremely pleased with the setup as far as I can tell and the venues seemed to have worked extremely well. I mostly want to reflect on a feeling that I have which is that GNOME seems to be experiencing a renaissance in the energy and focus of the community as well as the broader interest from other players.

OSS Leftovers

  • Why no more new AND successful FOSS projects in the last ten years?
     

    If you ask me, the new, successful FOSS projects should be project that fix, replace, rewrite, whatever… the really unglamorous, low-level tools, libraries and so on that would make that happen. Yes, I know that this is really unlikely to happen under current business models and until IoT everywhere, new iPhones every year and the like are perceived as higher priorities, regardless of their environmental impacts and, very often, sheer lack of sense.

  • FOSS Backstage - CfP open
    It's almost ten years ago that I attended my first ApacheCon EU in Amsterdam. I wasn't entirely new to the topic of open source or free software. I attended several talks on Apache Lucene, Apache Solr, Hadoop, Tomcat, httpd (I still remember that the most impressive stories didn't necessarily come from the project members, but from downstream users. They were the ones authorized to talk publicly about what could be done with the project - and often became committers themselves down the road.

    Stephen Jacobs (SJ) and I are co-teaching “Project in FOSS Development” at RIT this semester, which basically means “hey students, want to get course credit for contributing to a FOSS project?” The class is centered around 5 project sprints of two weeks each. The first 3 weeks of class are preparing for the sprint periods; the week before spring break is a pause to reflect on how sprints are going. Otherwise, class efforts will be centered around executing project work… (aka “getting stuff done”).

  • Lawsuit accuses PACER of milking the public for cash in exchange for access
    The federally run online court document access system known as PACER now finds itself listed on a federal docket. Its overseer, the US government, is a defendant in a proposed class-action lawsuit accusing the service of overcharging the public. The suit, brought by three nonprofits on Thursday, claims millions of dollars generated from a recent 25-percent increase in page fees are being illegally spent by the Administrative Office of the Courts (AO). The cost for access is 10 cents per page and up to $3 a document. Judicial opinions are free. This isn't likely to break the bank for some, but to others it adds up and can preclude access to public records. The National Consumer Law Center, the Alliance for Justice, and the National Veterans Legal Services Program also claim in the lawsuit that these fees are illegal because the government is charging more than necessary to keep the PACER system afloat (as is required by Congress).
  • Is the Most Massive, Illegal Paywall in the World About to Come Down?
    A groundbreaking lawsuit is poised to decimate what is arguably the most unjust, destructive, and it now sounds like illegal paywall in the world, the Public Access to Court Electronic Records, PACER. PACER is the federal government court documents repository. Every federal court document, for every case, lives in PACER. It’s essentially a giant FTP document repository with a horrendous search system bolted on, not dissimilar to EDGAR. PACER was created in 1988 to enable access to court records electronically. Initially available only in courthouses the system was expanded to the web in 2001.
