General Software Discussion / Re: Windows Networking, help me understand.
« Last post by superboyac on October 14, 2013, 07:26 PM »
Wow, lots of good info here.  Ok...I've also been reading about it today.

Here's what I'm thinking: I want to try the domain way of doing things.  It's what I've been used to in the corporate world, and I find it easy. I've never set one up myself, that's the only thing.  So i don't know how hard or easy it is.  But after it's set up, I'm familiar with all the folder sharing and networking procedures.  hmm.

General Software Discussion / Windows Networking, help me understand.
« Last post by superboyac on October 14, 2013, 02:23 PM »
I've been messing around with Windows networking for the past two weeks.  So many things I don't understand, and seemingly so many inconsistencies in the way things work that look exactly the same from the setup point of view.

Workgroup vs. Homegroup:
I initially was using Homegroups (Windows 7 and Windows 8 machines).  Then, it told me it can't share the root of a drive.  So I disabled homegroups and now use normal file sharing.

Some folders share, some don't:
Some folders from the same computer get shared properly, I can see it from the other and access it no problem.  Others don't.  Same permissions, same everything.  The one that doesn't work is a root drive, but I don't understand why that doesn't work.

Full control?
On some folders, I have full control for all users (everyone, administrators, guest).  Yet when I connect it is read only.  So whether someone has full control or read only...it really only works in read only.  I don't understand this.
1003
Here's a question:
For that video content delivery service, the maximum video bitrate in the pricing calculator is 3072 kbps.  Now, from what I understand, 1080p streaming requires at least 10Mbps.  I'm just going strictly by the bytes per second of video for that resolution.  SO I'm not understanding something about compression as it relates to streaming.  How can a company deliver 1080p with just 3Mbps?  But ultimately, I want to know how the kbps that I am paying for ends up looking like.  So...

How many kbps do I need to pay for to get:
480p?
720p?
1080p?

because obviously it's not the same as the kbps calculated for a normal 1080p file, which is a lot more than most isp's even provide residentially, yet all these people are able to stream 720p and 1080p.

I don't have time to answer with anything approaching the level of detail this discussion deserves ATM so for the moment I'll be shockingly brief.  :o

As long as there isn't a lot of motion to encode and you don't have to meet a standard like Blu-ray with severe restrictions on GOP length you can actually encode extremely high quality 1080p H.264 at extremely low bitrates. Screen captures from normal computer activity, typically the lowest complexity video you'll run across, can actually end up with a lower bitrate than CD Audio. Presumably you're talking about regular live video (talking heads or the like) which would be less compressible but if you use a good camera still not horrible.

The really tricky part is the streaming bit because it's a lot trickier than encoding for physical media. Essentially it comes down mostly to buffer calculations and understanding the streams and server technology involved. I recommend a trip over to the Doom9 forums where you can pick the brains of some of the best minds in digital video.

http://forum.doom9.org/forumdisplay.php?f=77
That's kind of what I was assuming.  I thought the buffers had something do do with getting around bandwidth issues.  I don't know how it translates calculation-wise...the question is still "How much kbps do I need?"

I don't know how ambitious you are, but Jupiter Broadcasting (producers of the Linux Action Show, CodeSnap, Unfilter, etc.) like these guys a lot. I'm a fairly regular watcher of their shows and I have to admit the quality and speed of the video stream coming through this new supplier is vastly superior to anything they had before. It even works great streaming to an iPhone on a 3G network.
This looks like a great suggestion, I would have never come across it.  I'm completely open to using services, I just am very wary of most popular ones because they tend to have more ads, are more expensive, and make me feel duped.

I was just looking at their pricing schemes:
https://www.scaleengine.com/pricing/

I like it a lot, very fair, very flexible.  This may be the one.
1006
So, you're interested in live streaming primarily? The title led me to believe something different.
Yes exactly.  I want to see how "good" I can make it without any services or minimal services from others.  Just live.

Once recorded, there are zillions of options, no big deal.  I already have youtube channels, vimeo channels, websites, etc.  But to do something live is another dimension.
1007
I just learned about an open source video streaming software called Open Broadcasting Software.  I'll check it out later.

Ren, I'm not trying to get exposure or upload anything right now.  I'm exploring the video streaming technology and trying to see how much of it can be done independently, how much it costs, how does it compare to hosted (easier) solutions.

It may very well turn out that it's just way easier to use ustream or stageit or something like that.  But the way I see it, I should be able to do it myself.  I have all the equipment for sure, the software is either free or relatively cheap.  The thing I'd need services for is bandwidth if there were more than a few people watching, which probably means a little bit more expensive webhost plan.  The other additional problem may be trying to do things like embedding a live cast in facebook or youtube.  First thing I'd try is to have a blank webpage with just a video stream in it, and I'll expand from there.

I found this on another forum:
704x480 x60 != 4x 704x480 x15

If you have 4 different camera, you have 4 different video stream.
1. calculate avg bandwith to 1 camera:
-codec? mpg2, mpg4, wmv, x264, other?
-keyframes every 10-15-20-30 frame?
Sample video 720x404 x24 700-2600kbps included audio channel
If your camera send audio+video 704x480 x15, and your video picture not change a lot... 700-1200 kbps = 100-150KB/s (good quality)

2. calculate upload speed and server download speed requirement:
Upload bandwidth: 150KB/s / camera => 4 camera 600KB/s => 6-7 megabit/s
Server download bandwidth: 30 users x 150KB/s (1 camera) = 4500KB/s ~ 50 megabit/s => 4 cameras/30 users ~ 200Mbit/s (peek time)
Avg speed 20Mbps.

3. calculate monthly traffic:
Avg 3 users and 4 camera use 12 hours each day, and 5 days per week:
3 users X 4*150KB X 4weeks*5days*12hour*60minutes*60seconds (monthly bandwidth usage)= 1555200000KB ~ 1518750MB ~ 1484GB / month ~ 1.5TB/mo
If you calculate your packet header, and your upload stream, other bandwidth...

3-5TB/mo enough
Avg bandwidth 20Mbps
Maximum bandwidth 30 users 4 cameras = 200Mbps


I think gigabit network speed with 5TB monthly traffic is enough.
I can probably use a similar formula (and post later).  My goal is to have a portable setup to be easily used with small audiences (less than 50 people, maybe even 10).

I don't know if this is a valid question, but even if a host claims to provide a certain amount of monthly traffic and bandwidth speed (5TB/month, 20Mbps), do I also have to worry about additional quality/reliability concerns?  And what do I need to ask them or know to ensure myself that it will work?  Let's say the specs are more than enough, but all of a sudden 100 people join and that screws something up because of some technical connectivity issue, blah blah.

General Software Discussion / self-hosted, high quality video podcast. How?
« Last post by superboyac on October 07, 2013, 04:19 PM »
I've come back around to toying with this idea.  I need help thinking through the technical details.  The first thread I did on this last year is here:
https://www.donation...x.php?topic=29624.50

I know that the online hosts like ustream are very good, very easy to use, sign up and forget it.  But...as usual, I want to know how to setup an independent solution.

Bandwidth:
Any bandwidth experts?  Please describe the bandwidth requirements needed.  I'm almost certain that a typical residential ISP can't provide the bandwidth.  Even the best residential services like FIOS only offer about 5 Mbps (~600 kilo-BYTES per sec) which is not enough for high quality video streaming.  So I'm assuming, bare minimum, I need a company to host the server for me.  But I want to know how to judge whether a host can provide the bandwidth I want.  For example, let's say I have a video podcast that 30 people are tuning in to.  Which companies can provide that best bang for the buck?  I already use a company for websites, and the easiest thing would be to upgrade the service to make up for the necessary bandwidth.  Then, I would compare that price to the price of actual hosted podcast sites.  My guess is that the ustream pro services (which are crazy expensive....like $200-400/month) are still more expensive.

Once I've figure that part out, then I will have to search for the best portable setup for this.  OS, software, etc.

Living Room / Re: Jazz Recommendation Thread
« Last post by superboyac on September 26, 2013, 12:46 PM »
My technique was sort of "spider web" and I recommend it.  If you have an album you like a great deal, look at the personnel.  Find albums by each of those and try to sample them.  The various quintets and other groups of Miles Davis is a good place to start.  Wayne Shorter, Herbie Hancock, Paul Chambers, Wynton Kelly, Bill Evans, Joe Zawinul.. I just never heard any bad albums by any of those guys.

Then when you find an album of one of the Miles "side men" that you like very much.. continue the process. Almost like a recursive algorithm. It just keeps fanning out.
I second this.  THis is how I found all my favorite stuff.

I had this debate recently with a friend, and this is the conclusion I came to:
I've done my fair share of audio experiments and I tend to agree with the article's point.  I can't tell for MOST of these audiophile issues.  I just can't tell if there is a difference or not.  I've tried listening to lossy vs lossless sources, I've compared cheap headphones to expensive ones, headphone amps...and ultimately, I just can't tell if it matters after a certain point, and it seems to agree with what the article is saying.

I think the mastering of music is a much more significant point.  There is an OBVIOUS difference to how music is mastered between the really good guys and the crappy guys.  anyway, probably besides the point.

There is an interesting evolution of emotions that one feels when you use something like XBMC with a zillion plugins to access different online media -- one can actually have the same evolution of emotions when using some radio-apps for mobile phones.

Stage 1 is you install some addons that have thousands and thousands of different radio stations (or tv shows or streams), and you feel an overwhelming sense of excitement and wonder at all your choices.

Stage 2 is you start looking for something that interests you and you realize how incredibly hard it is to find what you want amongst so much chaff, and it begins to dawn on you that maybe rather than 100,000 stations it would be nice to have a top 1000 that would help you find some good stuff.  And yet you still have hope that you are going to find some good stuff.

Stage 3 is the frustration that makes you want to smash something into your tv that comes when you realize that no one is making any effort to cull out the non-working links and streams, and that almost everything you try to watch/listen to either fails after timing out, or hangs the software completely.

That's the point when you would give your right arm for an app with 10 working links to some mediocre media streams.
lol...mouser.  I wish this thread existing 2 years ago when i first started looking at these things.  This is so refreshing (sorry!).  It's weird because the xbmc forums, as good as they are, will never be this brutally honest, obviously.  I'm reading all this and it's so exactly my same experiences.

A couple of months ago when I got my new desktop, that's when I first had the idea to use the old one for an htpc.  But of course, my first reaction was, it's soooo overkill and ridiculous, surely i can think of something better.  but I had already gone through all this xbmc stuff quite seriously.

but let me tell you, if i had a family, i would never get away with this.  the setup is pretty damn ugly, very bachelor, techy geek looking.
1016
mouser, since you are trying alternatives, give this one a short one:
get light alloy:
http://www.light-alloy.ru/download/

The reason why...if you want a file browser built for tv legibility, it has one built in.  So if you open the file browser from the right-click menu, you will see it.  It's a special browser built for large screen navigation.  That's all, just check it out.  I used this back when i had a tube tv and i couldn't read dopus clearly.

wraith, i'm having a hard time with your terminology.  what is your difference between a desktop box and a settop box?  i consider anything that runs normal windows or a user-installable OS a "full desktop".  are you referring to just the form factor?

What I'm using is the WD TV Live Hub (WD Link).  There are several out there like it... before this, I used the Asus OPlay.

They're closer to cable boxes than any computer... thus set top box.
I see.  Yes, then I suppose these are the middle ground devices between a full desktop and those cheapo android media players.  You're right, this is probably the best all around value for an htpc solution.  easy, plug and play, plays anything, cheap but well made, no headache, no configuring.
1018
re: the small android devices.  i have one (mk808b), it will struggle with true HD files badly.  And playback of even lesser HD files like 720p can be a problem.  I tried it for one day and never used it again.

wraith, i'm having a hard time with your terminology.  what is your difference between a desktop box and a settop box?  i consider anything that runs normal windows or a user-installable OS a "full desktop".  are you referring to just the form factor?

my gigantic tower i use for an htpc is, for sure, way overkill and somewhat noisy (i.e. not silent), but it is using 5 year old parts.  but even before then, I was using a desktop tower from 2002 (yup!).  This is up until this year, 2013.  And with XP running on it, it was equally powerful for most video and music purposes.  because like wraith says, for video, audio, and internet browsing, there's only so much benefit to power.  but the full desktop experience is still ideal in that you can install most software and it's very fast.  the only difference between the 2002 and 2013 experience for me is that with the 2002 computer, i couldn't play 720p or larger files.  but 480p played perfectly fine.  even seeking and jumping around the video file (my true measure of performance for htpc's) was great.  there's just something about a desktop experience.

i'll put it this way:
assuming you can play 1080p comfortably...i'd prefer a full desktop pc in whatever form factor and noise level, over any laptop, netbook, appliance-device, xbmc, jriver, android, "media player", etc.  I don't even care if it's 7 years old.  A desktop just has that ideal level of performance.  And i'm willing to bet that no matter what you're price point is, for the same price a desktop will outperform anything else.  The ONLY deal-breaker in such a case would be GUI.  If GUI is important to you, then the other choices might be better.

I recently was working with a lot of contracts and stuff that were being revised constantly, with multiple sets of documents that needed to be merged and inserted, etc. all the time.  I used this program:
http://www.debenu.com/

It basically allows you to create methods of batch processing a bunch of pdf operations.  For example:
--open document 1
--insert pages 3-5 of document 2 after page 40 of document 1
--merge this new document with document 3

etc

very handy, very speedy.  saved me a lot of headaches.  a little quirky and buggy at times (sometimes it would just crash).  but overall i was very excited about it.

Living Room / National debt/defecit: what does it REALLY mean??
« Last post by superboyac on September 18, 2013, 11:26 PM »
I have been wondering about this for a while, and I guess I was too embarrassed to ask.  What do these enormous negative numbers really mean for people individually and/or a nation?

Some stupid questions:
When do we have to pay it back?
Do we have to pay it back?
When is it too much?  If $1.6 trillion dollars equals life as it is today...what is life like with $10 trillion debt?
Who is it owed to?
Can they ask for it back?
If they can't, why not?
Is it because the US has bigger guns?  If so, when are bigger guns not enough?
If there's such a huge debt, why do the rich get richer?
If the poor who are getting poorer are the ones paying the debt, is it going to the people it's owed to, or the rich, or both?

Am I missing something here?  It feels like I'm missing something really quite fundamental because none of this really makes any sense to me.  And I'm not that bad with math, economics, numbers, logic, etc.
1023
Your $400 budget is the most difficult part for me to come up with helpful advice, i feel bad!  :-[

When I got a new desktop this year, I transferred my previous desktop ( a beast!) for my htpc.  I friggin love it.  But yes, it is loud.  i don't know how much an equivalent would cost, but most of the parts would be discontinued anyway, and it would be way over $400.  but basically, it's a full desktop computer with an i7 chip and 4 GB of RAM, and a 2009-middle of the road graphics card.  That's pretty much it.  I paid $3k for it 4+ years ago, so it should be way cheaper now.

Now, my exploration has been VERY similar to yours, so I'll just explain it, maybe it will help.  I messed around with XBMC, JRiver for a while.  But I found I was too used to the desktop experience.  So all these years, other than my experiments, my main setup is as a normal desktop.  I use regular desktop software...Light Alloy, Daum Potplayer to play videos.  An air-mouse for the cursor.  A wireless keyboard (very seldom used).  Directory Opus for the file manager.  Now, for years I also used a tube-TV.  The graphics (other than full screen video playback) looked awful, but it didn't bother me enough to change.  Now I have an LCD screen and it looks BEAUTIFUL.  Even 20 feet away, it's totally legible, with just normal font sizes.  I highly recommend getting one, if you are willing to spend.  So now, I'm not even that motivated to try other things like xbmc or jriver.

Everything is so fast on it.  The control, as you say, is awesome.  When i go to other people's houses and have to mess around with all their remotes, and tivo, and their cable "guides", and typing in the letters with teh directional keys, ugh, I get impatient.  i love double-clicking and going from window to full screen.  I love changing the volume with the scroll wheel.  I use foobar for audio, love it.  I know the computer is way overkill, so you can do it with much less also.  but because it's overkill, 1080p playback is instant, i love that.

The fan noise is significant.  It doesn't bother me, but now I just went and listened to it...if you like silence, yeah, it will bother you.  But I looked at cases recently, even for smaller form factors, and i think you can find some with large 200mm fans on them, and those are relatively quiet.  That might be the deal breaker though.  and the price of course.

I think the most important thing I learned about my htpc experience is:
--I just like using DOpus for picking the files.  I was really into the idea of doing the xbmc thing and properly organizing and tagging everything, but now I don't care.  I'll only do it now if i have a lot of time to spare and am into a new project.

bleach...i've talked a lot.  i should just take a video of me watching shit and post it.

ok, quick update.
i tried piggydb, didn't really take.  like 40 said, the interface is not really ready for prime time.  then i tried using a simple evernote notebook for my musical journal.  it didn't really take.  it was like i was forcing myself to come up with something to write.  i also tried The Journal, which I like, but basically the same thing happened.

i'm trying to do what my teacher has recommended, but maybe it's not the way for me.  i don't know.  i need to figure out what the root benefit of the musical journal really is and maybe there's another mechanism that is right for me.  this is like me in college...i never took notes and did great.  i found taking notes distracted me from listening, it was a huge failure for me.  but everyone recommended taking notes.  so i don't know.  i think my real goal is just that i have to sit down and play, focused and deliberate.

perhaps this calls for a $$ tool like Actual Window Manager.  It has lots of features, like a Desktop Divider, that will simplify this.
