Inline Skates in Koeln kaufen

Inliner in Koeln - wo sind die Shops ?

Wo kann ich in Köln Inliner kaufen ? Die größte Auswahl hat galeria-kaufhof.de . Passgenauigkeit bei den Skates sind nunmal sehr wichtig, weswegen ich sie nicht so gerne im Onlineshop bestelle sondern lieber selber an/ausprobiere.

Eine Recherche nach Inliner ergibt Treffer auf muskelkatersport.de und sportscheck.com . Deren Vorrat an Inlinern , vor allem was verschiedene Schuhgrößen angeht, ist aber sehr klein . Ein sehr großes Angebot dagegen bietet galeria-kaufhof.de, wo ich in meinen Online-Recherchen gar nicht drauf gestoßen war.

Review of "Untitled Rum 5 Years 40%"

Review of 'Untitled Rum 5 Years 40%'.1/5 stars by dr0i, November 2013 This rum is bad quality, at least the bottle I got. It's quite expensive (20,- euro), but it tastes shittier than a 4 Euro one. Maybe the bottle was standing too long in the sun. Maybe they took adhesive's to the flavour. My experience: "untitled rum" is undrinkable.

Losing my dyndns account

pascal.selfip.org is no more

The problem:

After 9 years of using dyndns for free to avoid the high costs of renting a static IP (60 euros per year by my German provider "netcologne") to use my laptop at home as a server, dyndns.org now takes money for their dns service - about 25 $ a year. There are several reasons for me not to pay, and so I lost the control about the subdomain "pascal.selfip.org". There are not to many references in the internet to this domain, but I find it sad. Hate broken links. (All the URLs of that subdomain were valid through all these 9 years, I made this for sure).

The content formerly found at http://pascal.selfip.org/ can now be found at http://pascal.dr0i.de/ . This is a subdomain of the domain I have rent at selfhost , and with the renting of that domain I got a also a dyndns support at selfhost which I need to route to my server at home. And all this costs only 18 Euros . Also I was able to pay via German bank transfer action ("Überweisung") which is superior to any paypal or mastercard/visa etc. because of security and tracking reasons. This is also why I decided against paying the 25 $ , which I considerd to do otherwise (at least for one year, to give the domain the HTTP status code 301 . (Dyndns gave me that chance to redirect, but I always said to me "ok, will do that next week". I had to log in once a month at dyndns to keep the account alive. Now, for 3 months I logged in once a month, but the last time I missed it. So that was that and sad. Anyhow, even if I would have given the status code 301, only the search engines which hit in that time frame would know about the permanent redirect. All the broken links stored in webpages will somedays be just that - broken links. Worse, they could be "hijacked" by someone who takes that subdomain and fill in with whatever content))

Lesson learned:

Using a dynamic IP is ok, but not for publishing URIs for your content! If you donot control the domain, what if e.g. the tenant of that subdomain decides to take it away if he wishes so , for whatever reasons? You are defenceless. From that follows vice versa: donot ever link to content to subdomains if you are not sure if the corresponding domain is in control of the people who provide the content . So, my strong advice, use a dyndns subdomain solely for routing purpose in the CNAME of your DNS entry for your real domain to route to your home server. As for my domain dr0i.de I do just that - and the switching form dyndns.org to selfhost.de for dr0i.de to mimick an expensive static IP has no bad side effects like those forever broken links for pascal.selfip.org . And if selfhost.de for whatever reasons will be unbearable for me, I will held my domain and swicth to another dynds provider or rent at least a static IP -  however, I will not have headaches with broken links.

May the links always be stable!

 

Artikel "Datenanreicherung auf LOD-Basis" erschienen

über die Online-Version

Ich habe letztes Jahr einen Artikel zum Sammelband "(Open) LInked Data in Bibliotheken" geschrieben. Gestern nun lieferte die Post 5 Bücher an den Mitherausgeber, meinen Bürokollegen Adrian Pohl. Schon schön, so ein echtes Buch in Händen zu halten :)

Das Beste ist aber: mit der Herausgabe ist das "Embargo" abgelaufen, und ich kann endlich eine Online-Version veröffentlichen. Diese ist nun selber Teil des LOD Graphens: sie hat eine stabile URI, die Ressource wird über HTTP ausgeliefert, und sie enthält sogar ihre eigenen Metadaten, die die Ressource mit anderen LOD Knoten verknüpft. Das alles ist sehr leicht herstellbar, da es eine HTML Ressource mit RDFa ist. Zum Anzeigen der Metadaten in Turtle kann z.B. der Distiller verwendet werden:

http://www.w3.org/2012/pyRdfa/extract?uri=http://www.dr0i.de/lib/pages/Datenanreicherung_auf_LOD_Basis.html

Die Online-Version kann in Kleinigkeiten geändert werden, z.B. durch Fehlerbereinigung, Formatierungsverschönerungen und Zufügen kleinerer, erläuternder Textbausteine. Es gibt aber keine Versionierung. Das ist ein von mir aus Bequemlichkeitsgründen vertagtes Problem, prinzipiell aber lösbar.
