PostPosted: Mon 02 Jul 2012, 01:41    Post_subject: Chrome Browser  

Doesn't Chrome start a new instance of the rendering engine for each tab opened? This is what gives it stability with "rogue tabs/webpages". So that's going to be a problem on any resource limited hardware like the Raspberry Pi. Presumably the complexity or otherwise of the webpages open in the tabs also has an effect.

Could be complexity - could be version of Chromium. I have had 5 or 6 tabs open in other Rpi Chromiums run . . . either Arch or a later than Squeeze
After trying to use 'Links' (I still have nightmares) just using Chromium is like geek heaven Smile

Just got Gparted working - see Barrys 3 libraries and my 4th needed library

Here is a video of Sap alpha2, recorded in alpha2 and uploaded from alpha2
http://youtu.be/m5GEv1KEAxM

Sadly it is only a partial screen capture - but that is due to the settings- you should see gparted working - oh yeah 'come on' . . .

. . . did I mention alpha2 is out? Rolling Eyes

Micko kindly send me an improved ffmpeg recording script - I did also have one from a couple of years back, Micks worked better.

USB keydrive appeared on desktop when plugged in.
We haz 'sneakernet'

I think I have worked out what is slowing and locking up Chromium
'Flash' (not the saviour of this universe) Wink

No change there then . . .

Gtkdialog seems to be working OK
tried an old script and changed the base of gtkdialog3 to gtkdialog4
and it worked . . .

Alpha2 is great!

Usb drive detection works.
Gtkdialog3 and 4 works.
Xsane (with usb scanner) works.
Cups (printer connected to router) works.
German keyboard layout works.
Psync works.

After first tests, I can see only one small glitch. After disconnecting usb drives, the drive icons doesn't disappear.

And no luck with sound, although I installed snd_bmc2835. But haven't tested much.

All in all, really great work, Berry.

@Mick and jamesbond,
yes, using cli worked. Thanks. I was able to extract, but didn't install because Alpha2.

Now reading the new MagPi.

from wiki:
6. Audio possibility -
http://mitchtech.net/raspberry-pi-audio/
aplay
what does aplay -l give you?
If it lists multiple cards, you can select the audio out by running:
aplay -Dplughw:X filename.wav
X is the card you choose from 0 to n
-------------
been looking at Ted
and siag office
and even Abiword beta
for any potential alternatives to Libreoffice . . .
Any suggestions? (these might be an add on in package manager not in Puppi)
Barry mentioned that Libreoffice might be too big for Puppi on Rpi
---
Before I forget:
Has anyone removed the Puppi SAP SD card and used a second card as a storage hard drive?
Working?

there must be something vital missing from my life. i have never found a need to have or use libreoffice. Crying or Very sad Laughing i dont even know what in it so cant be sure of what substitutes i am using. puppy already has most everything i need. just add java and portable opera and i am away. occasional video editing in openshot or kendive. sometimes messing in blender or in xampp or added games. i must just be easy to please.
presentations? is that what i am missing? printing?

I tried the alpha2 sap6-5.96 today and see some clear improvements!

The arrow keys are responsive: you can move the cursor on the screen, you can position the cursor before a letter and use the delete key to erase the letter, and you can use the up and down keys to scroll through previous commands in the console now. Surely a labor-saver!

I again tried CUPS for my HP Officejet 6500 e709n printer. This time I got the HPLIP driver package for HP printers from the Debian arm repositories, and was able to get a driver specific for that model...and a test file from Geany printed correctly.

The Puppy Package Manager still seems to be struggling to do its thing...it seems to want to install the program again after it reports having successfully installed it. Maybe I am doing something wrong.

I tried Sylpheed. An updated version 3.2.0 was available, which I accepted. I put in the details of my email account, downloaded a bunch of messages, and successfully sent a test message. So it seemed to be working O.K. on an initial small test.

I was able to open 5 Tabs in Chromium browser, but beginning with the third tab, things became progressively more sluggish. With the 5th tab things appeared to freeze, but with clicking on the "X" the 5th tab closed after 4-5 minutes. I think if I had tried to open a 6th tab I would still be waiting. The "cpu utilization meter" hovered near the top of the scale. I got some interesting numbers with the "free" command:

urxvt alone 48692 bytes free, 0 bytes swap used
urxvt & 1 Chromium tab, 3900 bytes free, 128 bytes swap used
urxvt & 2 chromium tabs, 4780 bytes free, 1196 bytes swap used
urxvt & 3 chromium tabs, 3848 bytes free, 6712 bytes swap used
urxvt & 4 chromium tabs, 2956 bytes free, 13616 bytes swap used
urxvt & 5 chromium tabs, 2228 bytes free, 98664 bytes swap used

Yesterday aarf said it sounded like the problem was insufficient RAM, and 2000 bytes doesn't sound like much reserve to open a tab and do much with it.

is there a way to hook one of these arduino shields to the pins


QUADRAM 512MB at $24.95

http://ruggedcircuits.com/html/quadram.html

sort of destroys the cost advantage.

News item HERE
VLC player won't run on Raspberry pi because it has ARMv6


Quote:
VideoLAN mobile team has finally launched the BETA version of its VLC media player named Neon for Android phones. It is available of all Android-based smartphones and tablets
An application most widely used on the desktop that has wide array of supported video and audio codes and can play almost any video is now on Android.
This player was recently released on iPhone.
However this app is only available for users with Android 2.1 or higher devices and will run on ARMv7 CPUs that support NEON media-processing engine.

Yesterday I did an update of the ppm
(it took nearly two hours)
Was looking for an alternative to Chrome
in Debian Squeeze main Shocked

Not so sure there is one I prefer . . .

I did not install Iceweasel (yes I have read the Debian manifesto) or surf.
Java and python dependent browsers - not for me.
Not too inclined to find opera-mini.
Barryk is getting more tabs open in Chrome/Chromium (not sure which is the OS and which the browser and Google in an effort of 'no-evil' disinformation is blurring the line)
http://bkhome.org/blog/?viewDetailed=02883
I also tried using the sync setting facility, so you can have bookmarks and setup the same across devices using Chrome
Not too successful and Seamonkey has something similar though less advanced.
My inclination would be to use Chrome as a modern, mega browser. Familiar to many.

Guys if you have a chihuahua, will you be putting a solar powered webcam + raspberry pi on it? Just an idea. A camera is one of the first planned daughter-boards Smile

@ Lobster
I tried aplay -Dplughw:X filename.wav, and yes, it works a little bit. This means, I get sound, but also some underrun errors (some drop outs) and after ~30sec it freezes.

Installed Aqualung, but it doesn't find any sound device. Well, not so important by now.

Also tried to update PPM, but after downloading the files, every line looks like
program name /usr/local/petget/find_cat: line1: syntax error: unexpected "(".

Also here. Choosing "Cancel" stops installing the 2nd time. First times I thougt that it was me, being less patient. Or my keyboard. Often it forgets a letter or a key "hangs" (like pressed permanently). I don't think, that it's a mechanical problem, too many different keys are involved. If I'm alone with this problem, it's nonetheless probablly my keyboard.

On the positive side, it seems to be easy to boot sap6 from usb hd. Also to use a swap partition there (you still need partition 1 of the sd card).
I think, antiloquax posted about that before, but can't find it Embarassed .

i just copied the content of mm0p2 to a free partition of a usb hd and changed in cmdline.txt root=/dev/mmcblk0p2 to root=/dev/sda1(the partition where my Puppy files are), and rootfstype=ext4 to rootfstype=ext3. At first run it took ~6 sec. longer (41sec. instead of 35sec.) Now I deleted the content of mm0p2 and also the swap partition on the sd card (I have one on the usb hd). Works fine.

~Rolf

Edit: Nice video today, Lobster Very Happy

Thanks Rolf Smile

Looking forward to alpha3. Looks like Barry has many tricks from no swap drive, fast file system etc - oh yeah.

USB keydrive was temperamental - several versions of the desktop icon and I could not transfer files from SAP to the drive - though I managed it the other way - onto the Raspberry Pi.

Another issue. On my early Debian (pre SAP) the image took up the whole screen - now it is partial both on the later Debian and consequently Puppi.


I did try using ffmpeg to record the video but without full screen success
xcowsay is a lot of fun - check it out
http://www.murga-linux.com/puppy/viewtopic.php?p=429491#429491

The video was run from a rather flawed bash script
recorded on Ipad and uploaded and edited on youtube

I will upload the script after I get it working a bit better.

Puppy Linux is Pawsome

I have Pi (the real type)

I can't get sound to work over hdmi but I can over analog. (May be the really cheap telly and hdmi cable Rolling Eyes )

Code:
modprobe snd_bcm2835
amixer cset numid=3 1


The "1" on the end forces analog.

Tried a DVD, plays, unwatchable Sad

Tried a CD, excellent Smile
