moved my htpc to raspberry pi... and back to "normal" pc

After using Raspberry Pi based HTPC with Raspbian for a while (see my previous posts) it was obvious that it hasn't made it for me. A few reasons:

• Trying to watch browser-based internet TV or just videos in the browser is too much hustle. It was much easier to connect my Mac and watch it.
• AirPlay is lagging on videos.
• Small one - for some reason it kept changing IP address on every reboot / power loss. There were more than a few. Btw, if you have your Raspberry Pi unstable, the first move definitely is to take a look at your PSU. It got much better for me when I changed PSU from a noname to iPhone charger. Google it before you buy.
• For me personally the combination with my receiver was not good: Pi supports HDMI starting version 2, but my receiver's "old" one from year 2008 and supports just 1.1 :D Sorry, no 5.1 sound with those beautiful Dolby Digitals, DTS's etc for me. I was thinking of buying external sound card, but, you know, why should I when I have some PC boards laying around the house having sound built-in with more "usual" connectors, like optical S/PDIF maybe?
• And, the most annoying one which was the final killer: user interface is too slow / lagging. I can't imagine why the distro can decode 1080p normally and can't do smooth user interface :| Especially, if you have a list of multimedia longer than one screen you wait for each next one, and next, and next...

I definitely could try to tune the thing or try other distros. Maybe I hoped that it will be more out-of-the-box initially. Maybe I'm not that much enthusiast or just too lazy :)

It definitely has the future, it just isn't here for me yet.

So, I'm back on my old good ASUS AT5IONT-I motherboard with pico-psu, 4GB of RAM, SSD for system disk. Good Ubuntu plus XBMC.

Some pics for the dessert.

moved my htpc to raspberry pi - couple of my answers to my own questions

Basically, there is no _practical_ WoL for the Raspberry Pi. It seem technically possible, at least they say that the NIC+USB chip HW supports it, but nobody f...ing needs it, so no project cares to make it. Everybody seem so happy about having a device consuming 5W max that leaving it on all the time seem more than normal even if it does productive work just a fraction of the time. Ok, let the time solve this, I'm happy too :)

Btw, there is WoL functionality for XBMC and their mobile remote. So, guys using it on the HW consuming tens of watts of energy, I encourage to try and to use it!

Cool feature of XBMC, Apple's AirPlay protocol, doesn't seem to work stable on Raspbmc. First, I was surprised by the functionality, you can't put the screen on the screen, you can just share photos, videos, music. Second, video is _very_ unstable and there are screen stretching issues which doesn't seem trivial to solve, you need to really dig into configuring the thing. I do not recommend it for now.

Btw, I had 1 Raspbmc crash since start, it just stopped to play internet radio once without obvious reason.

Otherwise, I'm still very happy with it.

moved my htpc to raspberry pi

Today I unwillingly decided to change my HTPC. It happened by the combination of two events.

First, I was thinking to add a Raspberry Pi to my multi-room audio system for some time already in order to stream saved music and internet radio and manage it by the mobile devices.

Second, I mixed up PSU's between above mentioned multi-room audio system and current HTPC after dusting them. Bad thing, multi-room has higher voltage (24V instead of 12-17V) than HTPC, so HTPC decided to get to be offended. I don't know what exactly broke, still need to find what got burned there. Good thing, I had urgent need for a new HTPC on my hands, thus motivation to act immediately.

NB It's a pity that you actually can't rely on all those different PSU and charger producers that plugs doesn't match...

So, XBMC on Raspberry Pi it is. Quickly googled and decided on Raspbmc. Very simple setup, just download it, dd it to flash card, plug it in and let it setup itself. After that you get your usual XBMC interface.

XBMC official iPhone app is even easier. And it's interface is better than XBMC's default one. Just easiness of the search function tells.

Btw, if you connect your Raspbmc to the network server for the media, be aware that XBMC may not be very efficient in the networking by default. My config stuttered HD videos by default via Samba and NFS. This helped my thinking, optimised it to flawless playback :) 

Now, some observations and, unfortunately, pitfalls, even thou hopefully short-term:

• Major one for me for now. If you take a look at the Raspberry Pi specs you will NOT notice that it supports HDMI revisions 1.3 and 1.4. My audio-video receiver (AVR) which I bought in 2008 supports 1.1 and back. Sorry guys, no backwards compatibility, it won't work, at least it doesn't for me. I noticed that HDMI is up to 2.0 now. So, now I'm thinking about changing the AVR, but those versions...
• Btw, talking HDMI revisions, my TV, bought the same year, is using HDMI revision 1.3. Conclusion: Philips was ahead of Marantz back in 2008 :D
• Annoyances. So, I can't put HDMI through AVR. It IS a pity because of the sound. Video I can put directly to TV. Of course, I could use just TV sound, but my Marantz's sound is sooooo much better. Fortunately, Raspberry Pi has a simple analog audio 3.5mm jack, so I can have a good sound. And you can switch on audio output to both HDMI and analog ports in XBMC. The annoyance: not all those digital wonders of nowadays like Dolby Digital or DTS, just a plain simple stereo. So, it works. The annoyance: I need one more analog audio output for the multi-room, which I haven't. And one more for the headphones... And I couldn't use my AVR for switching even if HDMI revisions were OK, because my AVR doesn't convert digital sound to analog (ask for this when buying an AVR).
• One of the best things happened. I'm going to save some electricity definitely: Raspberry Pi can't go much over 5W :) Previous HTPC's PSU was at 110W max and I'm quite sure it used 50W to max.
• There is no power-on button on Raspberry Pi :D You can switch it OFF from software. What about ON? WoL you say? WoL is much, much more sophisticated... And my children are so used to use a power button. For switching on, at least, because switching something off is what older people do, isn't it?

So, todo for me now is to:

• find a soundcard for my Raspberry Pi, that would solve my DD-and-DTS-like "problems", plus offload the processor of decoding those, I hope 
• buy 3.5mm audio jack splitter
• change my AVR
• invent a power button for Raspberry Pi or configure WoL (from iPhone app should it work)
• or all of those options...

Guys, if anybody wants to buy used medium-class AVR in a good condition, just let me know. It's a Marantz SR4001, just looked inside, there is minimal dust and capacitors look good.

cybersecurity day today for me #security #linux #truecrypt #opensource #keychain #apple #keychain2go

All of the following in one day (+night...)

Twitter told me that Critical Linux Flaw Threatens More Systems Than You Think today.

Updated my Linux-es tonight (Ubuntu server 13.10 and raspbian), noticed that simple update doesn't affect package in question :D Need to be persistent and upgrade package from source...

And left my XBMC box for the other day, it also runs on Ubuntu.

As mounting Apple's encrypted disk failed me last week plus it makes duplicate copies in my Dropbox, decided to look for alternatives. Moved to open software, namely TrueCrypt.

Interesting and convincing. Plus, now I can view it on my mobile iOS devices too :)

I used to store some passwords in some files... Finally it got me, too hard to manage and search. Need some password manager. For me as Apple user the obvious first choice was keychain plus Keychain2Go app to get it on iOS devices. Set up sync, nice! :) Now need to move passwords there gradually. The question remains, what about being dependent on Apple? Noticed 2 nice things about it: keychain is in Apple's opensource domain actually (!) and there are tools for export available. So, some day there will be integration.
