Out of Ink? Buy a New Printer

canon-pixma-mg2250.jpg

A couple of years ago, I bought a Canon Pixma IP4500 printer for approx. €80. The reason for buying was that I was able to print documents (concert tickets, etc) and the occasional photo. Generally, I send my photos to a lab, so I don't need an expensive state-of-the-art photo printer.​

Recently, I ran out of ink for the printer. The third time in three or four years. The IP4500 holds separate cartridges ​for each color. This means that I need to invest around €15 for each cartridge. Total costs: >€60.

While I was standing in the store, I saw a new Canon (color) printer for less than €50. This included the ink (for that model). Well, that was an easy decision. Out the 'old' printer and in a new multifunctional printer (Canon MG2250). It prints, scans and copies, while the old printer could only do one thing; print.

There are probably several persons out there that would recommend off-brand inks. Sure, it's possible to buy off-brand, but that introduces the hassle of:

  • removing of chips, and taping them to new containers, and/or
  • drilling holes to inject new ink into the container.
  • Resetting software by pressing 5 buttons with three fingers for 20 seconds to lure the printer into thinking that everything is alright.​ And this can (and will) re-occur very once in a while.

All that to save a couple of bucks.​ No thank you.

Anyway, I have a new printer (with ink), and the old one is heading for the garbage dump.
"Why not sell it", you ask? Well, no person will ever want to buy it (with no ink in it), since they can get a new printer WITH ink for less money. How fucked up is that?

I wonder if we will ever throw away a car, just because it ran out of petrol and buying a new car (with petrol) is cheaper.​

Cisco ISE: Change of Authorization (CoA) not working

We had a wireless security implementation at a customer site which consisted of the following components:

The setup included a wireless lan for guest access by using the Cisco ISE guest portal functionality.

We started by configuring the WLC's and ISE environment and having done that everything worked as a charm. A couple of days later we we were not able to connect to the wireless network.
The error reported in the ISE Authentications overview was:

iOS: Move Contacts Between Address Books

This posts isn't for those who only use one address book on their IOS ​device. I, for example have two different address books on my iOS device. The first is my private iCloud address book with personal contacts. For my work I have an Exchange account, with the associated Exchange address book. This works fine when you're NOT creating contacts on the iOS device.

iPhone Stuck At Infinite Loop After iOS Update

AppleInfiniteLoopSymbol.png

The old iPhone 3G got stuck in an infinite restore loop after upgrading to iOS 6.1.2 this evening. As you might understand, the misses was not amused....

The infinite restore loop means that it keeps saying that it needs to be restored from within iTunes, but after doing that several times, you tend to loose faith. After trying it several times on a Windows laptop I tried it on my iMac. While it was restoring for the who knows how many times, I did some research on the Interwebs. The results were not encouraging.

I started gathering information, and some tools (like Tiny Umbrella) to break it from its infinite loop. After the restore the iPhone booted just fine. No idea what made it break its loop. Could be coincidence, could be my iMac. No idea.​

Anyway, the misses is busy restoring the data. She (or iTunes) made a backup just before the backup. So all should be back to normal in a few minutes.​

Juniper SRX With DNS Proxy Service Enabled

Since the release of Junos v12.1x44D10 for branche SRX firewalls, Juniper added a feature called DNS-Proxy. This features enables the Junos device as a caching DNS server with several additional options. One of those feature is to define a Fully Qualified Domain Name (FQDN) with an IP address which overrides (if it exists) the entry in the 'official' DNS system on the Internet.

Use One SSL Certificate in an ISPConfig3 Configuration

Last year I implemented an ISPConfig3 configuration for personal use. Mainly to host some e-mail domains, and perhaps some basic websites. This setup relatively easy to implement a should have been a breeze to maintain.... Untill I got an email from the provider last Tuesday, mentioning that my Linux VPS was attacking other hosts around the world..... *GASP*.. my VPS had (most likely) been assimilated into a botnet of some sort, and it was flooding a ton of other hosts.

Apple Pulls Photo App Because Of Porn

There are lots of (portfolio) websites available for the enthousiast / pro photographers. Some are free, and some cost a couple of dollars/euros a year. The most popular are (in no particular order, but since I store my photos @ SmugMug....);

In general, Flickr is portrayed as a photobucket where people dump their photos and comment on others with the weirdest badges, just to get some attention.This was also the reason I stopped paying for my Flickr account.

Both SmugMug and 500px offer less 'noisy' features and lots of customization options, but the thing they all have in common; they offer an app (at least one) the give the users an excellent experience on their mobile devices (Android and iOS).
Also, each of these services allow (up to some degree) nude photos, and as long as it's artistic you shouldn't have a problem publishing your photos on these platforms. Especially when you mark them as nude/possibly offensive, etc.

This week, Apple pulled the 500px app from the Apple App Store, because it was too easy to find nude photos [1, 2], and this violates their terms of service. The funny thing is that most of these apps allow the user to find nude content, and Apple's mobile browser (Safari) being one of the worst.

Just today a got a new follower on Twitter with a username that didn't leave much to the imagination. I just followed the users website link (which opened in Safari) and 'stumbled' upon a Tumblr account with tons of nude photos. All it took was 1 click.
Talking about Tumblr.... They have their own app where you can 'subscribe' to these micro-blogs. So I guess that Apple needs to revise their App Store terms, because this is  ridiculous.
