Google's Youtube has some problems

According to several user reports Youtube has some technical problems causing monkeys have lot to do. On the other hand , it seems, that not only Youtube is facing some internal server errors, but there is a problem to Google's HTTP servers, too.

So what are, the symptoms?

The most well known problem is Youtube's internal server errors, making videos unreachable. The problem is present at least since yesterday, make me beleive, that this is not a planned maintance action. Moreover, the fact that they haven't still fixed it, tells me it's some serious problem. Fortunately, not the whole service is down, perhaps due to load balancing, so you can get the video from a working server.

Also it seems, that the storage isn't affected, because nobody reported any data loss, so don't panic. But if I were you, I wouldn't upload any video, until this issue is present.

Google's ad service also facing the same issues, causing some ads unavailable. What a shame, isn't it? :-D ( Perhaps, due to the new feature, where ads are videos. too )





 
Finally, even I can't get the message about highly trained monkey ( probably Skipper's chimp partners ), because of HTTP service's unavailability.



We cannot speed up recovery, so have one choice...live our offline life. So, go for a walk and enjoy air!

Margin Call - Krízispont - Kevin Spacey most is a kaszinóban, de a kártyát otthon hagyta

2008 őszén csődbe jutott egy patinás New York-i brókercég, a Lehman Brothers. Ez az esemény, azonban nemcsak az ő végüket jelentette, hanem egy gazdasági válság kirobbanásához is vezetett. Bár a filmben nem szó szerint erről a pénzintézetről van szó, de a történet a Lehman Brothers körülbelül két napjáról szól a válság kirobbanásának kezdetén. Egy újabb tőzsdés film mondhatnánk, viszont később kiderül, hogy valami sokkal mélyebb mondanivalója van. Nem csoda, hogy 2012-ben Oscar-díjra jelölték a legjobb forgatókönyv kategóriájában.

Székely hónapnevek

A Maradj talpon vetélkedő egyik kérdésében vetődött fel, hogyan nevezik februárt a székely naptárban. Érdekelt a többi megnevezés is, ezért barátunk a Google egyik találatában megtaláltam a többi megnevezést is:

Downmixing 5.1 channel audio to stereo

I had some recordings, that contain AC3 audio with 5.1 channel audio, but I needed a copy from these video files with stereo sound. I usually use ffmpeg for video recoding stuff, so primarily I searched for a solution for this program.

Firstly, I found several forums, where other guys were talking about similar problem. It seemed, that the only solution is to add a patch to ffmpeg's source code and rebuild it.

Other guys used Audacity to downmix the audio. They used a WAV-files, which contained the 6-channel audio and for decoding 6 channel audio was used ffmpeg.

Well, I was more satisfied with the second solution, but a didn't want to use Audacity for this task, because I considered, that making a WAV file with 6-channel uncompressed sound data isn't very elegant :).

So my final solution became this:
- I extracted with VirtualDub the AC3 sound data to a WAV file ( which contains the compressed audio data, so it's a single AC3 audio file )
- Using ffmpeg tha AC3 audio file was converted to a stereo MP3 file (It isn't clear to me why it works, perhaps the patch was included in the latest versions)

The ffmpeg command was: ffmpeg -i audio.wav -ac 2 -ab 160k audio.mp3

The -ac 2 option says, that the user wants a 2 channel output.

Végleg eltűnt az UARS

A NASA tweet üzenetei alapjai az UARS műhold Kanada Alberta tartománya fölött megsemmisült. Ezzel véget ért egy elég különleges éjszaka, amely során ezrek követték figyelemmel egy műhold utolsó napját.

A www.nasa.gov/uars oldalon további információkat lehet olvasni e műholdról. Többek között az oldalon működött egy számláló, mely az űrben eltöltött idő mutatta, viszont ez még a lezuhanásról szóló hír után is működött:


Egy másik blogbejegyzésemben próbáltam követni a műhold utolsó pár óráját, ami sajnos nem tartott sokáig: az angol nyelvű bejegyzés

További szép napot mindenkinek, aki olvasta ezt a bejegyzést!

UARS - The falling satellite

Hi guys!

I tried to follow the position of the satellite UARS (Upper Atmosphere Research Satellite ), which is returning to the Earth these hours. I had a little problem to find a working website, but finally the www.infosatellites.com and www.heavens-above.com/ are quite good.

On the other hand, there should be a couple fo people, who doesn't have access to these sites, so I decided to publish som data on my blog. I hope you'll enjoy it and I can refresh it.

Update 3 (final):
I think, the most exciting parts are behind us. I hope you have enjoyed this night, even if you didn's see the UARS. Thank you, who have visited.

R.I.P. UARS.

Update 2:
Possibly the UARS is down for now. At least according to the tweets of NASA. Most possibly it landed in Canada.
