[LLVMdev] [RFC] LCSSA vs. SSAUpdater ... FIGHT!
So, there are two primary ideas behind SSA form management in the loop optimizers of LLVM: - Require LCSSA form input, leverage its (very powerful) guarantees to simplify maintaining SSA form, and also maintain LCSSA form. - Don't bother with LCSSA form input, assume the worst, and use powerful incremental SSA formation utilities built on SSAUpdater to form SSA on demand when needed. (Note,

getGraphicsEvent on X11 and event queuing
... I just realized that setGraphicsEventHandlers or getGraphicsEvent could have an 'onIdle' callback, to be called somewhere in the polling loop of gevents.c:163 - I think this would solve my problem #2 in a minimally disruptive way.

getGraphicsEvent on X11 and event queuing
Hi R-Devel, I've been working on an oscilloscope project using an Arduino microcontroller board. I found that it's quite easy to get realtime updates, e.g. 30+ frames per second, if I read data from the board in a little Rcpp library. I have to use dev.hold() and dev.flush() to keep the plot from flickering, which restricts me to the "cairo" X11 device. I'd like to be able

Hum/bux on line
Rich Hi, After Qwest pronounced my circuits as within spec. (yes, disconnected from the house) I listened on the lines with my butt set. Clear of all noise and hum. I then got my box of Cat3 and laid a circuit around the outside of the house and into my lab. Still clear of all noise and hum. I then connected the circuit to the Adtran and made a call. Lots of hum and buzzz. As I said,

R packages to send plottable data to external apps
I was curious what R packages, or indeed any other applications, exist to plot streamed data from arbitrary data generators. It need not be publication quality plotting but it should be easy to use like an oscilloscope. I was working on something called datascope that I am using for 1D finite difference monitoring and recently interfaced it to freefem. I also created an R package. If there is

Intel 536ep as a FXO?
Hi, I've seen some reports about ruuning Intel modem with 537 or MD3200 chipset running with Zaptel drivers as a FXO port. Did anybody managed to set up a PCI faxmodem based on Intel536ep chipset to work with * and Zaptel drivers? Modem seemd to work just fine with Linux, but the driver says no;) some more info: Linux 2.4.26 mazuchna:~# cat /proc/pci | grep 536 Communication

Optascope port trouble
OPTAscope was produced by Parallax in 2002, but has been discontinued. It's a USB PC Oscilloscope. I used WINE to install it OK, but can't get hardware connected. Using Ubuntu 8.10. Here is how a normal windows install goes. Install software, plug in hardware, "New Hardware found", then go to Device Manager and find port the device assigned. In my case, it was port 3. Go back to

Electronics Workbench 5.2 has misc. problems in Wine
Hello, I installed Electronics Workbench 5.2 (old version, but I have to import some work which I did using it) on Wine, mostly it works well, but: - When I close it, it enters an Access Violation/"Internal Error" loop. - Can't see text in some controls. For an example, check this image: http://img14.imageshack.us/img14/2707/75952076.png The controls in the 'Oscilloscope'

unacceptable utility voltage rate of change
Hi, One of my APC devices reports: "unacceptable utility voltage rate of change". I believe it has something to do with input voltage fluctuating too fast maybe even beneath or over the input voltage thresholds. Should I worry about this? should I measure input voltage? (I suppose I'd need more than multimeter readings. Maybe an oscilloscope or a multimeter that can record

RFD: With echo and other distortion, can ulaw/alaw line quality ever be good enough for faxing?
Folks, I've been following recent discussions regarding echo and echo training with much interest, since it's a problem we've never been able to eliminate here. We're facing two challenges presently, and they may be related (or not): a) Cisco 7960s in the office here echo back to our staff, but the customer hears decent sound. b) We've yet to be able to pass faxes through

GXP-2000 Volume Issue
Is anyone else having an issue with GXP-2000s and transmit gain? All my other phones are fine on my TDM400P with txgain set at 0, but the GXP-2000 caps at about a third of the scale in ztmonitor. I'm getting people complaining they can't hear me on my GXP-2000s, whereas my Snom 320 and Polycom 301 are great, and my Budgetones are overmodulating. Is there any conceivable fix on the

Random Disconnects - or ARE they?
I have one use on our PBX who has been experiencing seemingly random disconnects. The user is on the same LAN as everyone else, using the same type of phone (79XX loaded with SIP firmware) as everyone else. He had some disconnects a few weeks ago, I suspected the phone, so I swapped his with mine. I have since not had issues with his old phone, however, he has had issues using mine. So, the

Woodpeckers Revisited
Just when I thought I couldn't be wrong, I was wrong. We have woodpeckers that drill into the arial telephone cables, and water seeps through the holes and partially grounds the tip and/or ring wires causing hum. I thought the hum/buz on my lines was a telco problem. The Qwest HQ noise team assures me that my lines are within spec. Sure enough, when I listen on the test set the lines

Can't connect USB Serial (COM3)
Wine does great job for GUI on screen (PC Oscilloscope) But, can't USB connect to external hardware device that has FTDI 245AM chip in it. See device in /dev/ttyUSB0. See device in lsusb, also in lsmod. Did normal linking, ln -s /dev/ttyUSB0 /.wine/dosdevices/com3. No luck. See the link with: ls -al of dosdevices. Using COM3 because in Windows registry in Wine, it says COMPORT=3 Any help?

PATA Hard Drive woes
Hi All. Yesterday I was installing Centos 5.5 to my web server, and it looks like the main hard drive has gone AWOL. Fedora 12 put the file system into r/o mode. The drive is an Hitachi, still under warranty. There are bad sectors on it, and running the Hitachi DFT tool confirms this. Also I cannot repair the bad sectors. Would this be caused by a faulty I/O chip, or is it safe to say
