RPi Hackday

http://www.meetup.com/squidwrench/events/119509752/

I put the RPi hackday in the meeting slide show this month but completely failed to actually put it on the calendar. It's still happening, though, so if you have time / inclination come check it out.

I have about 4 extra RPi's showing up today, so if you don't have one you can pick one up on Sat.

Road closure at Vassar College

For those that approach Vassar from the south end, the road onto campus off Raymond Ave between the south parking lot and the main gate (Chapel Drive) is now closed for the week. If you are coming to campus tomorrow night for the meeting and coming from the south end of Raymond Ave (From IBM, Wappingers Fall, whatever would cause you to be on Hooker Ave) be sure to plan to enter through the main or north gate.

Ben

Recommendation for reliable home office wireless router'

Hi - I'd like to upgrade my wireless router in the house to something more reliable than what i have now, which is a netgear n300. The devices using the router will be my macbook air laptop, an hp laptop, 2 android phone, 2 android tables, and a wireless printer. Obviously not all will be on at the same time, but primarily the mac laptop and the hp laptop would be the devices using the network mostly.

So what i'm trying to get around is the fact that every home wireless router i've had needs to be reset every month or so. This router is particularly annoying since I need to reset it every few weeks. Instead of buying a new low-grade router i'm looking to buy something more beefy.

So i'm looking for something that i can use that's reliable and doesn't need to be kicked every 30 days. I'd be looking for something that can sit on a shelf in the basement and that doesn't take up too much room. I don't need many ethernet ports. The only critical requirement is that the wireless is solid and stable. 802.11n would be nice, but i'll take g if it's more stable.

Recommendations...?

Thanks!

[ANNOUNCE] MHVLUG Meeting - Wednesday, May 1st at 6 pm

+-------------------------------------------------------------------+------------+
|------ MID HUDSON VALLEY LINUX AND OPEN SOURCE USERS GROUP [1] ---| *Follow� Us*|
+-------------------------------------------------------------------+------------+

MHVLUG is proud to announce our May meeting:

------ ASTERISK: TELEPHONE COMMUNICATIONS AND MORE -----------------------------

Do you need an extensive communications system? � Asterisk is an open source
solution that turns an ordinary computer into a communications server. Asterisk
powers IP PBX systems, VoIP gateways, conference servers and is used by small
businesses, large businesses, call centers, carriers and governments
worldwide.�

Andrew Sledgianowski is currently a systems administrator for The New York
Internet Company.

.... Lightning Talks

* ZoneMinder - Patrick Ladd
* F-Droid [5] - Joe Apuzzo
Before the main talk we will do a series of lightning talks (up to 3), each 10
minutes or less, on something Open Source related. It could be a fun new
program, a book, a blog post, or really anything you think the wider MHVLUG
community would find some interest in. People that have posted their talk
subject to the website in advance have priority. Time permitting, we'll also
take impromptu lightning talks from the floor.
The meeting space opens up at 5pm for pre meeting general discussion, question
asking, show and tell, and setup. All are welcome to join. If you are planning
on using the projector for your lightning talk, please arrive at 5:30 to ensure
we can work out any kinks with the projector prior to the meeting.

The meeting will take place at Rockefeller Hall 200, Vassar College [6] on
Wednesday, May 1st at 6 pm.

All meetings are free and open to the public, and everyone from all levels of
expertise and interest in Linux and Open Source Software are encouraged to
attend (and bring a friend or two)! After each meeting ends everyone is welcome
to join in on an informal dinner gathering at the Palace Diner on Washington
St.
This is a great opportunity to interact with members of the local Linux
community, and a forum where questions and comments are strongly welcomed.

For more details, including maps and directions, please see the meeting page
[7].

Show your support for MHVLUG by RSVPing at our Meetup Page [8].

Fw: [Test-Announce] Fedora 19 Graphics Test Week starts 2013-04-23!


The Fedora Graphics Test Week is an opportunity to test the latest open
source graphics drivers.  If there is an issue on your current install,
you can see if it still happens on a live image with latest versions of
Xorg, Mesa, and DRM.

-- 
Support the Free Software Foundation - www.fsf.org

From: Adam Williamson <awilliam@...>
Subject: [Test-Announce] Fedora 19 Graphics Test Week starts tomorrow (2013-04-23)!
Date: 2013-04-22 23:46:09 GMT

Hi, folks. It's that time again: Graphics Test Week! Tomorrow 
(2013-04-23) is Intel Test Day, Wednesday 2013-04-24 is Nouveau Test 
Day, and Thursday 2013-04-25 is Radeon Test Day:

https://fedoraproject.org/wiki/Test_Day:2013-04-23_Intel
https://fedoraproject.org/wiki/Test_Day:2013-04-24_Nouveau
https://fedoraproject.org/wiki/Test_Day:2013-04-25_Radeon

This is one of those events where we really need as much data as 
possible - the idea is just to get testing on as wide a range of 
hardware as we can manage. So please, if you have a few spare minutes, 
come out and test! It's very easy. Live images will be available on the 
Wiki pages soon (martix is just finishing those off), and we'll be in 
#fedora-test-day all week to help out with testing and debugging.

There's a longer announcement post on my blog at 
http://www.happyassassin.net/2013/04/22/fedora-19-graphics-test-week-kicks-off-tomorrow/ 
- if you want to spread the word about the event (and please do!), 
that's probably the best thing to link to.

Raspberry Pi and Serial Communication

This might get long, so here is the short story:

I'm attempting to ssh into a Raspberry Pi and then use the USB port to communicate directly with a Cisco switch using a usb to serial adapter and an RJ-45 console cable. This causes crashes that are repairable by powering off the Pi and rebooting.

Here are the details:

Hardware:

RaspberryPi, version 2 (512MB RAM)

16BG class10 micro SD in an SD converter

USB to serial adapter on /dev/ttyUSB0

Serial to console cable

Cisco 2950 Switch

Software:

OS - Rasbian [note: I've run `apt-get update` but not `apt-get updrage` at this point due to time considerations)

SSH - installed and enabled

Minicom - installed and set to the Specs specified by Cisco for console communication (9600 8N)

What has happened:

I've been able to ssh in and create a new user and such. No Problems here. After installing minicom, I have had only spotty success with seeing any output from the Cisco Switch.

I have been able to communicate with it twice, but both have ended with the Pi crashing. At first my computer reports that `the host is not responding.` Then I eventually get `The host is down`. This is when I have to reboot.

However, those two successful attempts are only two on many attempts. There have been Many times (at least 10) when I ssh in, run `sudo minicom`, and once minicom is running, I get no response from the interface. The `^a` to get to the menu works and I can exit minicom.

During these times when minicom is not producing output from the switch, there have also been the same crashes as explained earlier.

Questions:

1 - Have you had any experience with serial comunication over the USB port on a Raspberry Pi? What are your results?

2 - As I said earlier, I haven't run `sudo apt-get upgrade`. Do you think this will solve the crashing issues? How about the non-responsiveness in minicom?

3 - I've tried several different levels of overclock. Do you think this timing has anything to do with the serial communication flakiness?

4 - Minicom specific issue: What's the difference between "exit and reset" and "exit without reset"? I'm guessing it has something to do with keeping the switch output in a buffer until I come back, but I haven't had enough successful communication attempts to know for sure. If I exit minicom the wrong way, will it bork future communication attempts?

Thanks,

Al

Wireless mouse on Ubuntu 12.10

Greetings again.

I have a fresh (right of Live-CD) install of Ubuntu 12.10 - not much done to it so far other than updates and Chromium install. It is not a dual boot, I put the SSD in and have only installed L\Ubuntu to it.

I am trying to get my wireless trackball - Logitech M570 - running and so far not having much luck.

Computer is a Sony Vaio Laptop, I7. It has it's own internal BlueTooth.

I have tried the bluetooth "Setup new device" (after checking that BT is actually on with Bluetooth Settings screen) and the scan never sees any device. I have also confirmed the battery works in the trackball.

I have tried inserting the supplied BT dongle and using that both wioth the laptop BT on and off - nada. the trackball works both with the old Windows install on this laptop as well as gets a nightly use on my work system.

Lots of web results on setting it up, etc, but most results I have found so far are along the lines of "after you have paired your device...." some info I have found appears to be for older distros (8 predominates) or other versions (Mint, etc) but no one seems to actually have a problem actually pairing.

There is some indication that it may be "Easier" to pair in Windows, then shift (dual boot) to Linux - but I am on a 100% Linux install right now and that isn't an option. Other sites indicate this isn't really needed at all.

I feel I am just not doing something right or are failing to find and edit the correct config to insure that my system can see this thing - any thoughts?

Prov. 12:15

Eschew obfuscation and pompous prolixity.

Light a man a fire, he is warm for the night.
Light a man afire, he is warm for the rest of his life.

LP154W02-TL06 LCD NVIDIA resolution problem

Briefly spoke with Sean about this last night.

I've got this maddening NVIDIA driver problem; the IBM LCD screen for this 
15.4" Phillips LP154W02-TL06 has an EDID that is SNAFU such the newer Nvidia 
driver (which checks the EDID) will only allow going to 1600x1050 mode.  This 
then causes problems trying to do TwinView between monitors (or using a 
projector) whenever the other monitor doesn't support this resolution -- which 
naturally is always the case.

I've tried using these options in xorg.conf:

   Option "UseEDID"      "False"
   Option "UseEdidFreqs" "DFP-0:False"

... but when I use these, starting Xorg causes Xorg to hang, and the screen to 
go black.  Restarting X doesn't help -- never comes back.

If someone else has gone through this and thinks they might know of a fix 
(however doubtful it may be), please email this thread.  I've put a lot of 
effort into this, and right now I'm down to making a custom EDID file by hand 
based on known Modelines, and it's a rediculous job.

Thanks.  ;)
