Funk me Amadeus!

Seit geraumer Zeit haben viele unserer Hersteller angefangen, immer mehr Geräte mit LoRa-Technologie oder zusätzlicher WLAN-Funktionalität auszustatten sowie auf LTE-Empfang umzustellen. Die Vorteile liegen meistens auf der Hand:

  • Schlecht erreichbare Messpunkte können professionell angebunden werden
  • Messpunkte ohne Netzwerkzugriff können über LTE mit einer sehr guten Bandbreite angebunden werden
  • Einige Sensoren benötigen keine Messstation mehr, sondern können direkt mit der entsprechenden Monitoringsoftware kommunizern
  • Oft ist eine Kopplung bestehender Sensoren und Infrastrukturen möglich, da es durchaus Funkadapter für Sensor-Kabel oder potentialfreie Anschlüsse gibt
  • Vermeidung von Black Holes im 3G Mobilfunkbereich

 

LoRa-Technologie

Hier kann unser Hersteller AKCP auf ganzer Linie punkten, denn das L-DCIM ist ein drahtloses Mehrzweck-Sensor-Gateway mit LoRa™ Funktechnologie, WiFi, Ethernet und zwei USB-Eingängen und verfügt über einen integrierten AKCPro Server, der Überwachungsplattform von AKCP. Mit dem L-DCIM Gateway können die Daten von AKCP Sensoren – egal ob verkabelt oder über Funk – empfangen werden. Genauso können Geräte von Drittanbietern über SNMP oder Modbus überwacht werden. Mithilfe der Funk-Sensoren kann die Überwachungsumgebung einfach durch Hinzufügen weiterer Sensoren skaliert werden. Mit der Kombination aus L-DCIM Gateway und AKCPro Server können z. B. sämtliche intelligente Netzgeräte überwacht werden, wie PDU (Power Distribution Units), USV, Gleichrichter oder Klimageräte/-anlagen.

 

WLAN

HW group bietet hier zum einen die SD-Reihe an, die per WLAN direkt ohne zwischengeschaltete Basis mit der HW group eigenen SensDesk-Monitoring-Lösung kommunizieren kann. Sie verfügen alle über WiFi, Ethernet und PoE und sind in einem Metallgehäuse für die Hutschienen- oder Rackmontage erhältlich. SD-Geräte können alle Sensoren von HW group anschließen. Sie verfügen auch über Ausgänge, die über SensDesk gesteuert werden können. Direkt oder über Bedingungen.

Auch aus dem Hause HW group kann unter anderem das STE2 mit WLAN-Konnektivität aufwarten. Das STE2 ist eines unserer beliebtesten Messgeräte: Nach 4 Jahren und 13 000 verkauften Einheiten (leider nicht alle durch uns verkauft ;-D) hat HW group dieses Jahr nun ein Revision unter dem Namen STE2 R2 präsentiert. Auch das WLD2, das wir letzte Woche in unserem Blogpost vorgestellt haben, hat im Gegensatz zu seinem Vorgänger nun WLAN-Anschluss. Aktuell sind wir gerade dabei, beide neue Geräte-Versionen bei uns im Shop aufzunehmen und sie für Euch verfügbar zu machen. Solltet Ihr nicht solange warten können, dann lasst es uns wissen!

 

LTE-Standard

Wie die Überschrift bereits deutlich macht, ist LTE oder 4G mittlerweile nicht nur in der Technik und Industrie ein fester Standard, sondern auch im privaten Alltag. Man hat sich quasi an die hohe Bandbreite und die schnellen Übertragsungsraten gewöhnt. Und solche Bequemlichkeiten gibt man ja auch nicht mehr gerne auf.

Nicht nur bei den Geräten aus den Bereichen SMS-Gateways (SMSEagle, Braintower und MultiTech) oder LTE-Routing (Teltonika und AMIT), auch viele Messgeräte sind mittlerweile mit LTE-Funkverbindungen ausgestattet oder damit ausgerüstet worden. HW group bietet sowohl das Ares 10 als auch das Ares 12 als LTE Versionen an. Beim Hersteller AKCP gibt es z. B. den sensorProbe2+ auch mit optionalem 4G Modem.

 

Als Fazit können wir hier ziehen, dass einiges auf dem Markt aktuell in Bewegung ist. Selbstverständlich versuchen wir, auch mit unserem Angebot im Shop immer auf dem neuesten Stand zu sein – sollte uns dies einmal nicht gelingen und ihr vermisst ein Produkt, dann kontaktiert uns. WIr helfen gerne weiter!

Wir sind jederzeit für Euch erreichbar per Mail: shop@netways.de oder telefonisch unter der 0911 92885-44. Wer uns gerne bei der Arbeit ein bisschen über die Schulter schauen oder den Shop und die angebotenen Produkte verfolgen möchte, kann uns auch auf Twitter folgen – über @NetwaysShop twittert das NETWAYS Shop Team.

Is there a Company Backing PostgreSQL?

That’s a question I got asked when I was helping out at the PostgreSQL booth at this year’s FOSDEM.

I replied “yes”. And a second later, “there are even several!”.

But although the nerd density at FOSDEM is ridiculously high, I’m not sure he got that boolean joke “Are you going for lunch now or later?” “Yes.” … so, in the faint hope that, that guy will stumble upon this blogpost and hopefully as a nice read too many others, let me elaborate on that a bit.

PostgreSQL was Initially a Research Project

Back in the 1970’s, even in the US, universities could do research on things that would not directly lead to a patent for the corporate sponsor and a spinoff (owned predominantly by the corporate sponsor). They even received public money for such kind of research (whoo!), often from the DARPA.

Michael Stonebraker and Eugene Wong, who started PostgreSQL’s predecessor Ingres, were funded by a couple of military agencies, more detail here.

Stonebraker in fact did the spinoff “stunt” with Ingres which exists until today. However he returned to Berkeley to continue research on a “Post-Ingres” system, “Postgres”. Yada yada yada, long story short, Postgres was basically handed over to a group of enthusiast who kept working on it and turned it into PostgreSQL over time (we’re discussing the mid-90’s here). Some of those initial enthusiasts are still actively working on the project btw., one, Bruce Momjian, even attending FOSDEM on a regular basis!

It Today is a Community Project

The database system today is “owned”, which is in fact impossible due to the ridiculously open license, be the PostgreSQL Global Development Group, a non-profit that mainly runs the different postgresql.org sites. Alongside, there are several national & international non-profits, e.g. PgUS, PgEU and countless local usergroups, see the community page to get an idea.

… that allows a lot of Companies to generate Profit of it

So, people started doing serious stuff with Postgres, ran into problems and had them resolved, wanted advice on certain issues, get trained, or just someone to look after their databases on a regular base. Companies were founded, that specialised on PostgreSQL support and consulting. Some of these vanished, some still exist.

Some of these companies offer proprietary products that base on PostgreSQL. Also, there were “spinoffs”, companies that took the PostgreSQL code and ran with it, making something new of it. Just as well, some of these still exist and make good business.

… which some Feed Back partly into the Project

Many, if not most, of these companies contribute to PostgreSQL one way or the other. As a matter of fact, the vast majority of the core team members and major contributors work for a handful of companies.

Still, these people are probably working for those companies, because they are major contributers. E.g. Tom Lane these days works for Crunchy Data, but has been working for e.g. Red Hat and Salesforce before (rumours are that Salesforce hiring Tom was a huge factor in the Salesforce-Oracle “war” and led to their 2013 partnership – most probably due to a massive discount that Salesforce were willing to agree to…).

Corporate contributions are mostly code by hiring people, who hack on PostgreSQL and money by sponsoring infrastructure or events.

The community is rather small, so is the circle of corporate players. At the end of the days, everyone knows everyone and is engaged in a coopetition.

Most corporate code contributions stem from their customers’ requirements. Some improvements go to the proprietary variants first, very few go there only. However, the ultimate goal usually is to get a feature into the core product, so mainline, community PostgreSQL.

So how does this Model differ from Other Popular Projects?

Linux

These days, when we mention the kernel, we usually mean Linux, that has the Linux Foundation, essentially backed by all major players in IT, which realised that Linux is useful to them and decided to fund the development (essentially ending the UNIX wars).

There are only few, if at all, companies that “span off” the kernel, but the vast majority of code contribution these days is coming from corporations or their employees.

Some of these in turn “sell” Linux as distributions, essentially subscriptions today. Their share of Kernel contributions is a huge selling point.

Others, take NIC or SCSI controller manufacturers for example, were initially (like, 25 or 20 years ago) just hoping to sell a few more of their products by offering some nerd enthusiasts specs and technical documentation. Today, they know they just can’t sell anything that isn’t properly supported by Linux, and thus are willing to hire full-time developers to ensure so.

All of those contributions still go over the “benevolent dictator“‘s desk or one of his aides’ and thus have to fulfil certain requirements. And the distributors agreed years ago to only include mainline features in their products, to avoid fragmentation.

A major difference to PostgreSQL: all those companies (distributors aside) use Linux for their resp. products, not as their product.

MySQL / MariaDB

MySQL initially was written by the founders of MySQL AB, which was acquired by SUN in 2008, which in turn was acquired by Oracle in 2010.

While being an Open Source product and even being GPL-licensed as Free Software, MySQL was never renowned for being very open to contributions, however MySQL AB and SUN were striving to improve the product, based on what the “community” was wishing.

Oracle, being the major player in the RDBMS market, obviously has no interest in improving a “free” piece of software to a degree that it could effectively cannibalise their core product … so, the MySQL founders founded MariaDB and took a significant part of the MySQL developers with them.

Both products still evolve, but development is steered and driven by Oracle and MariaDB respectively (no idea what I should think of the MariaDB Foundation, to be totally honest), so probably to a good degree by the marketing departments and in Oracle’s case, fenced by the limitations from “above”.

Sure, you can get support from independent companies (many of those also offering PostgreSQL services, btw.). However, any large customer like financial institutions, the public sector, etc. prefer to go “straight to the source”, so chances are that offering support will stay a niche market. Percona maybe being the exception.

MongoDB et. al.

The “NoSQL” market is (IMHO) to a certain degree a reply to the pricing policy of RDBMS vendors and the “better safe than sorry” mentality of many IT managers. But that’s a different story …

However, a certain pattern has evolved over the last years:
Some Open Source projects become popular, companies are founded, the development is centralized there, conferences and trainings are offered etc.
And at some point, someone decides that actually earning money would be a nice idea …

So, an “enterprise” product is introduced, or a dual-license model, or a cloud service with limitation of competitors’ ability to offer such, etc. pp.

In essence, these are often Open Source products, but not Free Software. They sometimes get crippled beyond recognition.
The communities could sometimes be called that way because the mawning people in the forums are “managed” by “community members”.

Is this healthy? Couldn’t a Company buy PostgreSQL, like Oracle did with MySQL?

Short: No.
Longer: Sure, e.g. Oracle could probably buy one or most of those companies, but the product PostgreSQL is not “theirs”. I mean, even MySQL was forked after the acquisition of SUN …

We’ve seen PostgreSQL companies get bought, sometimes they even disappear from their “natural” markets.
But that had no significant impact on the project’s structure, pace or harmony.

PostgreSQL

  • is “smaller” than MySQL, Linux or many other important FOSS projects
  • we don’t have the Kernel.org power
  • nor Oracle’s cash and licensing department
  • is not controlled by any single entity, thus
  • “more free” than many other “open source” projects/products
  • can not be bought, shut down or in any way be tampered with
  • will never change its license
  • will never disappear
  • yet feeds a lot of mouths directly and many, many more indirectly, like your humble author here
  • many contribute back one way or the other

PostgreSQL is much closer to the Linux model, coopetition of many companies, plus a fair share of “private” contributors, than to any other Open Source DBMS, relational or not.

This worked very good for the last 25 years, and I doubt it will ever change.

As someone (was it Bernd Erk?) coined:
> “PostgreSQL doesn’t have a community, it is one!”

I second that!

Gunnar “Nick” Bluth hat seine Liebe zu relationalen Datenbanken Ende des letzten Jahrtausends entdeckt. Über MS Access und MySQL 3.x landete er sehr schnell bei PostgreSQL und hat nie zurückgeschaut, zumindest nie ohne Schmerzen. Er verdient seine Brötchen seit beinahe 20 Jahren mit FOSS (Administration, Schulungen, Linux, PostgreSQL). Gelegentlich taucht er auch tiefer in die Programmierung ein, so als SQL-Programmierer bei der Commerzbank oder in App-Nebenprojekten.

Current State of Icinga

In the talk „Current State of Icinga“ Bernd Erk shortly introduces himself and the team behind Icinga. Bernd’s presentation gives at first a quick overview over Icinga, followed by a really funny presentation with Emojis (Long story short: Icinga makes you happy!). After that Bernd explains the blog, the ongoing user survey, IcingaConf, Icinga Camp and Icinga partners all around the world. He also presents the reason why we don’t know most of the Icinga users: As it is an open-source product, anyone can download it and use it for free.

In the main part Bernd gives a product update for Icinga and everything connected to it. Thereupon he reports about what happened during summer 2019 regarding development. After that he goes deeper into the new features and innovations of Icinga version 2.11, which is the current major version as of November 2019. In the second part of the main presentation he illustrates Icinga Web 2 and the new features of the current version 2.7 (November 2019) and its accessibility features. vSphere version 1.1 is the third main theme and Bernd touches on its new features and improvements. The topic after vSphere is Icinga Director and its current version 1.7 (November 2019). Bernd discloses the new features of the Director and what it is capable of. He completes his talk with aspects of Icinga Business Process Monitoring in its newest version 2.2 (November 2019). Here the main components are the Drag & Drop feature, Export & Import and Usability. With regard to this Bernd presents the mentioned features and innovations in a short live demo.

After the live demo Bernd introduces Icinga for Windows. A short video of the installation of Icinga on Windows is shown. Christian Stein, a long-standing member of the Icinga team, is the main developer of this outstanding Icinga innovation. After having presented Windows monitoring, the focus moved on to Icinga for AWS (Amazon Web Services) version 1.0 (November 2019) and its possibilities. Thereafter Bernd goes in deep with the Icinga module for JIRA in version 1.0 (November 2019) and how it works.

Icinga DB is the last topic covered. For that a few last year’s slides were repeated, followed by a funny video about why it took so long. After this hilarious video a live demo of all the new features and innovations is given.

Bernd concludes his talk with a summary:

  • Icinga Director 1.7.2 is out now
  • Icinga Module for vSphere 1.1.0 is out now
  • Icinga Module for JIRA 1.0.1 is out now
  • Icinga 2.12 RC will be ready later

And that is basically Bernd’s entire talk, though highly compressed. If you are interested in the full talk with all its details and funny moments I recommend watching the whole video. It is worth every second, entertaining and highly informative.
