Adding more to the thermostat

Adding more to the Raspberry Pi Having already basically created a thermostat using a Raspberry Pi and a temperature monitor in conjunction with the WiFi power socket I was wondering what functionality I could add. Having looked around for a bit I found that there is a camera module available which can pick up infra-red […]

My Browsing Environment

I did a huge cleanup of my firefox profile today, which resulted in me removing tons of stuff (from dead bookmarks to useless addons to many other subtle or not that subtle stuff).
The whole process helped to return firefox in a rather working/healthy state, but also served as a good reminder of something i had in mind for quite a while now.
I wanted to document my firefox setup once i decided that it is stable or has reached a state that pleases me usability wise (hard if you consider all the changes that happened to it throughout the years).

This post serves as a good linkable source too for all those that ask me how i configure my firefox and a list of addons i practically recommend (through my own usage of them). So without further ado:
For simplicity and to give their usage in a glance i have separated them in 4 distinct categories. The list is of the form “Addon - reasoning”, i didn’t include links since all of them are readily available on addons.mozilla.org

Safe Browsing

NoScript - Blocks many stuff (js, flash, java etc) can allow whitelisting of sites that you deem safe enough to allow their code to run.
RequestPolicy - Similar in spirit to NoScript but for any cross site requests.
Certificate Patrol - Monitors and shows changes in certificates (suspicious or not)
HTTPS-Everywhere - Defaults to HTTPS by default for those sites that provide it but not offer it as the default redirect
Privacy Badger - Pretty much covered by the others but there to catch anything the others might actually miss
RefControl - To see and track what the Ref header sends to the site i visit.
Priv3 - Blocks tracking by social buttons (like, +1, etc)
Self-Destructing Cookies - Self-Explanatory addon. once i leave the site, the cookies go BOOM!

Quality of Life

GreaseMonkey - Allows me to overwrite or extend site behaviour through js
Stylish - overwrite the site CSS (really a must for more sites than i can count)
Session Manager - I always had issues with tabs management with the default manager, this solves it
uBlock Origin - Ads! many of them are so distracting and intrusive i just don’t like them.
Reddit Enchancement Suite - I browse Reddit A LOT, this makes it a tad more bearable.
Cleanest Addon Manager - with that many addons…
Google Search by Image - To make finding the source of an image quicker …

User Interface/User Experience

Pentadactyl - I am a vim and a very keyboard/keybinding heavy user, this adds better kb based control.
Socialite - Shows the current vote rating on reddit for the link i browse or allows me to quick submit it there.
The AddonBar (restored) - Firefox removed the addonbar recently, this brings it back.
Config Descriptions - I fiddle a lot with about:config sometimes, this adds explanations.
Tree Style Tab - a must, a way better visualization of the tabs i open and their relationship.

Misc

Rikaichan - This allows me to get an explanation of an unknown japanese word by just hovering it with my mouse.

Just to see how things evolve (or hopefully progress) i’ll also be keeping track of this and updating/making a listing yearly, seeing how my browsing environment will have changed by next June!

Some more geeking around at home …

Continuing the techno-geekery at home As written in a previous post I’d bought some wireless controlled electrical plug adapters primarily for use to remotely control the air conditioning unit in The Son’s room, especially in the evenings after he had been put down for the night. The adapters are controlled via a smartphone application, and […]

openSUSE – proprietären Grafik-Treiber AMD Catalyst 15.5 als RPM installieren

AMD Catalyst 15.5 (fglrx 15.101.1001) wurde veröffentlicht und unterstützt Grafikkarten ab Radeon HD 5000 und höher. Das Skript makerpm-amd-15.5.sh steht ab sofort zum Download zur Verfügung und unterstützt openSUSE 11.4, 12.1, 12.2, 12.3, 13.1, 13.2 sowie bis Kernel 4.1 (offiziell nur bis Kernel 3.18).

Neue Features:

  • Support for SUSE® Linux Enterprise Desktop 12

Gelöste Probleme:

  • [417630]: Fixes the issue of discrete GPU not being powered off in Power-Saving mode on some PowerXpress AMD GPU + AMD APU platforms
  • [416499]: Fixes minor screen corruption when resuming from S3 caused by display hot plugging

Bekanntes Problem:

  • [419960]: Vari-Bright on some configurations is not decreasing brightness as expected

Link: AMD Catalyst 15.5 Release Notes

Wichtiger Hinweis: AMD hat leider versäumt, dass richtige Packaging Skript in den AMD Catalyst 15.5 zu integrieren. Daher lasse ich ein aktuelleres Packaging Skript über das Skript austauschen. Der Treiber stammt noch von einem älteren Entwicklungszweig und ist mit dem neueren X-Server 1.17 auf Tumbleweed nicht kompatibel. In diesem Fall empfehle ich bei AMD Catalyst 15.3 Beta zu bleiben. Zudem kann ich leider bei dem neueren Treiber nicht mehr garantieren, dass der GNOME Desktopmanager funktionsfähig ist.

Folgende Steam-Spiele habe ich getestet und laufen mit diesem Treiber (Fettdruck = Neu):

Eine kleine Bitte habe ich: Wenn irgendwelche Probleme mit dem Treiber auftauchen, scheut euch nicht mir zu berichten (Ich nehme deutsche und englische Bugreports gerne entgegen). ;-) Ich werde versuchen, soweit es mir möglich ist, den gemeldeten Fehler zu reproduzieren. Zusammen mit den nötigen System-Informationen werde ich mich direkt an die richtige Stelle bei AMD wenden, um den Bug in der nächsten Treiber-Version beheben zu lassen. Danke schön. :-D

Für Benutzer älterer AMD Grafikkarten (Radeon HD Serie 2000 – 4000) wird dringend die Installation dieses Treibers abgeraten. openSUSE bringt bereits für ältere Grafikkarten den freien Radeon-Treiber mit. Um regelmäßig Verbesserungen am freien Radeon-Treiber zu erhalten, ist die Installation eines neuen Kernel unumgänglich.

Installationsanleitung:
http://de.opensuse.org/SDB:AMD/ATI-Grafiktreiber#Installation_via_makerpm-amd-Skript

Installation guide (English):
http://en.opensuse.org/SDB:AMD_fglrx#Building_the_rpm_yourself

Über das makerpm-amd-Skript

Das Skript makerpm-amd-15.5.sh ist sehr mächtig, robust und läuft vollautomatisch. Der AMD-Installer wird automatisch heruntergeladen, falls er nicht schon im Verzeichnis liegt. Zudem wird geprüft, ob die Grafikkarte vom Treiber unterstützt wird. Auf Wunsch wird nach dem Bau des RPM-Packages der fglrx-Treiber installiert.

Folgende Argumente können dem Skript übergeben werden:

-b Nur das RPM-Package bauen (Standard)
-c <type> Nur X-Server konfigurieren. Monitor-Typ: single = 1 Monitor, dual = 2 Monitore (Wichtig: Nur ausführen, wenn es Probleme mit der Standardkonfiguration des X-Servers auftreten)
-d Nur den AMD-Installer downloaden
-i Das RPM-Package bauen und installieren bzw. updaten
-igf/–install-gdm-fix installiert einen Fix, um den Treiber mit dem GNOME Desktopmanager (gdm) läuffähig zu machen
-kms <yes|no> Kernel-Mode-Setting (KMS) aktivieren oder deaktivieren
-nohw Hardware-Erkennung explizit ausschalten. (z.B. beim Bau in einer VM)
-old2ddriver <yes|no> den alten 2D-Treiber aktivieren oder deaktivieren
-r|–report erstellt ein Report und speichert diese in eine Datei namens amd-report.txt
-u|–uninstall entfernt AMD Catalyst restlos vom System. Zuerst wird das fglrx-Package (falls vorhanden) vom System deinstalliert. Danach werden vorhandene AMD-Dateien und -Verzeichnisse entfernt. Hinweis: Falls das Rebuild-Skript installiert wurde, wird es ebenfalls entfernt und das Initskript /etc/init.d/xdm wiederhergestellt.
-ugf/–uninstall-gdm-fix entfernt den Fix, dass den Treiber mit dem GNOME Desktopmanager (gdm) läuffähig macht
-ur|–uploadreport wie Option –report nur zusätzlich wird der Report auf einem NoPaste-Service sprunge.us hochgeladen und gibt bei Erfolg den Link zurück.
-h Die Hilfe anzeigen lassen
-V Version des Skript anzeigen

Hilfe, es funktioniert nicht!

Bitte haltet folgende Regel ein:

  1. Bei der Eingabe der Befehle auf mögliche Tippfehler überprüfen.
  2. Möglicherweise ist die Lösung für das Problem im Wiki vorhanden.
  3. In Kommentaren lesen, ob eine Lösung zu einem Problem bereits existiert.

Wenn keines der o.g. Regel greift, dann könnt ihr mit eurem Anliegen an mich wenden. Damit ich euch helfen kann, müsst ihr erst vorarbeiten. Bitte ladet euch das Skript makerpm-amd-15.5.sh herunter und erstellt einen Report von eurem System in der Konsole:

su -c 'sh makerpm-amd-15.5.sh -ur'

Das Skript lädt das Report auf sprunge.us hoch und gibt anschließend einen Link aus. Diesen Link postet ihr in eurem Kommentar zusammen mit einer Beschreibung zu eurem Problem an mich. Ich werde mir euren Report anschauen und Hilfestellung geben, wo evtl. das Problem liegen könnte.

Feedbacks sind wie immer willkommen. :-)

mdds 0.12.1

I’m happy to announce that mdds 0.12.1 is now out. You can download it from the project’s README page.

There are primarily two major changes from the previous release of 0.12.0 as explained below.

multi_type_vector

One is that multi_type_vector now has a new static method advance_position to increment or decrement the logical position of a position_type object by an arbitrary distance.

static position_type advance_position(const position_type& pos, int steps);

The implementation of this method has been contributed by Markus Mohrhard.

flat_segment_tree

Another major change in this release is with flat_segment_tree. Previously, flat_segment_tree had an unintentional constraint that the value_type must be of numeric type. In this release, that constraint has been officially lifted so that the user of this data structure can now store values of arbitrary types with this data structure. The credit goes to David Tardon for adding this nice improvement.

Other than that, there are no other changes from 0.12.0.

mdds on GitLab

Incidentally, the mdds project now has a new home at gitlab.com. The new URL for the project page is now

https://gitlab.com/mdds/mdds

If you need to include a project URL, be sure to use the new one.

Thank you, ladies and gentlemen!

openSUSE transformation step 2. The user oriented distro.

openSUSE Tumbleweed is a rolling release that was designed with a clear goal, target and metric. It was developed following a clear picture of where to go. Design it was a painful but unavoidable process that challenged an assumption established in many people mindset back in 2012. Latest/greatest and stability were incompatible. Hence, Factory, the rolling release back then, was for hardcore SUSE/openSUSE OS developers only. As rolling distros, there were more popular and better options out there.

This summary might help you to get some background.

Goals are easier to achieve if you have a good reference to beat. For those who worked in the project, Gentoo and specially Arch Linux were those references. As you can imagine, transform openSUSE required management support. We had it, specially from Roland Haidl, Operations and Communities Director at SUSE back then. He created the environment that allowed those who worked in his department to be creative.... and take risks.

Simplifying, for the new "development version", a.k.a Tumbleweed (former Factory), the goal was to implement a model that allowed us to improve the existing Factory one, based on continuous delivery. The target chosen were our core contributors (packagers fundamentally) and the metric was, in summary, to make sure that, no matter how wrong things could go after an update, you would always have a console and network, so you would be able to revert your change. In terms of the process, the resulting integration deployment processes should be transparent, not just internally but also from our community members perspective. It also needed to be simpler in order to gain contributors, not just users. And it needed to empower them to own it.

Instead of following what SUSE was doing back then, the company dedicated resources to challenge itself. As result, openSUSE Tumbleweed is today, not just the best rolling distro out there, with all what that means in terms of excitement among its contributors, but is generating higher value to SUSE, since the company have an outstanding playground at home that allows them to incorporate true innovation into their production process before their competitors do.

openSUSE is discussing nowadays to take a second step, this time focused on its user oriented version. Today is openSUSE 13.2.

In my opinion, based on the previous experience, and independently of the decision/discussion process chosen, the same steps need to be taken. They are unavoidable in any transformation process. It is necessary to define a clear goal, something short that you can explain and understand easily, a clear target and a key metric that helps to clarify the "acceptance criteria" to be used during the whole process.

Like back then, I would like to see SUSE challenging itself, putting in question well established principles within the OS industry. Again, choosing a reference would make the final picture easier to achieve.

Most openSUSE users are desktop users and sysadmin. If, as I conclude from the latest oSC15 videos and factory mailing list discussions, sysadmins are the chosen target, It would be great to see SUSE/openSUSE challenging the assumption that, through a continuous delivery process, you cannot release a stable and high quality (for the target) distribution. That stability is only achievable through a waterfall like model. I would choose CoreOS as reference. It is a project that, based on different questions, is providing innovative answers to new challenges.

I would like to see that, base on the current process (standing on the shoulders of giants) openSUSE/SUSE creates a process that "pulverize" the current mindset, deprecating many of the existing problems, focusing on solving new ones. Imagine the best of both worlds, a new paradigm of OS with the green values.

It took about a year and a half for a dedicated team to release what today is Tumbleweed. I think that this second challenge is bigger than the first one. An even bigger commitment from SUSE will be needed in order to succeed.

But if the resources are there, the creative environment is set, the right steps are followed and the openSUSE community supports the effort, there is nothing that can stop the project to achieve what today are dreams. SUSE has the talent, and the experience, to make it happen.

I wish them all the best in this new challenge.

The Running Geek … part 2

As I was saying … At the start of this year I’ve tried to go running using bluetooth earphones, and met with mixed poor results. Alongside the bluetooth earphones I had also decided to try and do away with bringing my phone with me whilst running. I previously owned a Sony Xperia Z, and the earphone […]
