Journal Journal: CuBox Wifi Streaming Solved

I believe I have mentioned before that every bit of media I purchase I digitize and store the files on a central server. That includes over 300 movies and over 100 television episodes, plush a few hundred audio tracks. Everything is available anywhere in my home via wireless streaming, however I had been having problems with reliably streaming 1080p HD video over WiFi to my main television units.

My back end device is simply a Buffalo AirStation AC 1750 running DD-WRT build 27456. It is configured for WiFi AC-only in the 5.8 GHz band, and G/N/AC in the 2.4 GHz band to accommodate some older devices.

A Western Digital My Passport Ultra 2 Tb USB 3.0 drive is plugged into the back of the wireless router, which acts as a NAS and makes media available via SAMBA shares.

Over all I like this set-up, though after several months of use I can't really recommend the Buffalo AirStation for the simple reason that it doesn't have any external antennas. It really suffers in coverage area because of this. DD-WRT is great, as is the little 2 Tb WD drive, but I'll never again get a wireless gizmo that doesn't use an external antenna.

The front end to my televisions scattered throughout the house is a CuBox i4-Pro running OpenELEC. This is a fantastic combination that has been almost -- but not quite -- perfect for me. It is also easy to use for my non-technical wife and future geek 7-year old child.

The one issue has been reliably streaming 1080p HD videos to a CuBox. Even with the unit less than 10 meters away from the access point, with no obstructions, it would routinely have such a poor connection as to not be able to keep up with the playback. Watching the dashboard of DD-WRT showed me it had less than 30% signal strength and constantly would drop to 5.5 Mbps connection rates.

To eliminate interference I got up in the middle of the night and shut off everything that used wifi except the CuBox and it still performed poorly.

The short answer is the built-in wireless on the CuBox is abysmal. Again, no external antenna and 2.4 GHz only. Further investigation showed it would not work with channel bonding, thus not use 40 MHz channels in 802.11n. I don't know if it is a chipset limitation or a driver issue. Either way, it sucks.

My answer was to buy a USB wifi adapter with an external antenna. This one is tiny, totally plug-and-play, and absolutely does the trick. And for $12.99, including Prime shipping, a bargain. It is marketed towards the Raspberry Pi, which is what I bought it for. It uses the Realtek RT5370 chipset and is supported at the kernel level (no extra drivers needed) in Android, OpenELEC, Raspbian and lots of other Linux flavors.

It support 802.11n and bonded, 40 MHz channels and, more importantly, handles HD streams without breaking a sweat. I just ordered 2 more to outfit my 2 other CuBox devices so I can stream everything to the TVs in bedrooms without running wires.

(Note: I'm in a fairly low-population subdivision and not a lot of 2.4 GHz wireless around. I'm not stepping on any of my neighbors with my signal.)

Journal Journal: Why libressl is stupid 2

I really want to like libressl. But it pretends to be openssl badly. They refused a patch that would have mitigated this whole RAND_egd problem by simply returning that it doesn't work when someone tries to use it, which means that you commonly need a patch to use it at all. If it's not going to work like openssl, then it shouldn't occupy the same space in the filesystem.

Journal Journal: Slowness of Slashdot

Slashdot used to be superfast

No matter where I happened to be - be it in America, in Asia, in Europe, in Africa or in Australia, - Slashdot loads up fast

No matter if the device is a smartphone or a desktop PC, you could almost always count on Slashdot to load fast

But no more

Now Slashdot takes something like 10+ seconds to load, and sometimes it took more than half a minute to load

What happened?

Has Dice shrunk the pipe to the Slashdot server?

Furthermore, Slashdot has been giving a lot of troubles, lately

Just now I was reading back stories on Slashdot, and when it hit " http://slashdot.org/?page=2 " the Slashdot server gave me this:

No matches found. Try a different search or head back to the main stories

What gives???

Journal Journal: OMFG GNOME3 is asstacular

This is not news to most people, but I just tried it for the first time on my first-ever normal Debian Wheezy install (I've always done minimal, netinst etc. and built it up from there for a purpose) and wow, GNOME3 is amazingly horrible. It makes Unity look usable. If that was the idea, mission accomplished, I guess.

Journal Journal: Magnetic Cell Phone Docks 6

Just a short note. I picked up an Air Dock back when their Indigogo campaign was under way. I have now had this thing for a little over a year.

In general it works fine and does exactly what it says. I use the CD-mount, which has a nice picture down on this page.

The one flaw with that mount is the bolt and nut used to tighten it are fairly large, and extend beneath the mount. On DIN I sized radios, with the CD slot on top of the unit, the nut blocks the view of the display.

The one other thing I have discovered is that after a year of use, it has magnetized my phone! The Nexus 5 comes with small metal plates built in to the back to allow for the native use of devices like this. After all this time they have become magnetized, and that totally screws up the internal compass.

Now any time I start the compass app it complains the magnetic field strength is way too strong and it doesn't give accurate readings.

To be clear, this happens when the device is undocked and I'm walking around.

My next dock will be non-magnetic, as I do sometimes use the compass.

Journal Journal: What do I have to enable now? Fucking DICE. 5

Welp, I can use Slashdot in Chrome and not in Firefox, which implies that something I'm blocking in Firefox is preventing the new improved Slashdot from working. What new spyware bullshit do I have to enable to use Slashdot now? Thanks, DICE! You'll run this place the rest of the way into the ground any day now.

Then they modded down five of my comments in a row. Why doesn't the system catch this kind of obviously abusive moderation? Oh right, because this is slashdot, not someplace with competent employees.

If moderation on slashdot were intelligently designed, this person's abusive moderation would have been autodetected and they would have been banned from moderation permanently.
