Hi- > I haven't seen a machine in which OR is faster than ADD nor more energy-efficient. They're all done by the same ALU circuitry which delays the pipeline by its worstcase path timing. So, for modern processor hardware purposes, OR is exactly equal ADD. Transforming ADD to OR isn't strenght reduction at all. Maybe this is benefical only if you have a backend generating circuitry

Has anyone managed graceful shut down from an Eaton unit with either of the ushhid or bcmxcp drivers? Generally speaking, the UPS will signal when it reaches a low battery state, regardless of whether the UPS publishes runtime statistics, battery percentages, or any other

Hello all: I am interested in using Speex for an application that streams audio from a (noisy) source, so I am interested in VAD and DTX operation. However, after browsing the archives of this list, I note that a number of people have not been satisfied with the operation of the VAD algorithm in Speex. This leads me to a few questions: - Is there a reference somewhere (other than the source

Hello all Nill experience with LVM. Have a Default Centos 4.4 install updated till a week ago with three HDDs. System's not booting up since my staff pulled out the plug due to a short circuit nearby. Machine is a PIII 550 MHz, with 3 HDDs 40 GB, 120 GB (Actually is bigger but my bios detects only upto 120 GB) & 20 GB...about half filled with data & the backup server taken out in

So where does this leave things regards Eaton and shut down? Has anyone managed graceful shut down from an Eaton unit with either of the ushhid or bcmxcp drivers? Perhaps I should be coming at this from the other end of the stick. What manufactures have the best support in NUT that I can look at and be confident I'm likely to have a successful deployment? Really the only deal breaker

"The fact that the loop is unrolled explains why the XORs, SHLs, and ORs are not folded into 1." I dont see why the unrolling explains it. "I think he is trying to say this expression generated by unrolling by a factor of 4 can indeed be folded into a single XOR, SHL and OR. " Precisely. The code generated by unrolling can be folded into a single XOR and SHL. And even if it

I'm trying to spec out hardware for a new office, and I'd like to include power over Ethernet as an option. I've seen a handful of PoE injectors around $1000 for 24 ports and a couple switches up around $2500 for 24 ports. Are there any cheaper options, short of buying a boatload of 1-port injectors off of ebay? I don't really need more then 24 ports of PoE out of 48 total

So historically I've done one of two things on systems where I've needed to use MeetMe * used a real Digium card, and I've only ever used a TE400 or a TE420 for that purpose, and I know they have the timing chip * used dahdi_dummy, which works well with light load, but I had it running on a very overloaded server and had audio quality issues. I may have had quality issues even with a

Greetings all; I pulled a Belkin F6C100-4 into the shop this afternoon, deader than a door nail. Out of service for about a year because (I'm assuming here) that the cooling fan stopped and cooked what little remaining life there may have been out of the batteries, which had swelled so badly I had to split its frame to get them out. They are also in the under 1 volt per 12 volt pack

Hi, I'm trying to configure my ups with nut which is a locally made one. It uses a rs232 port to talk to the computer and comes with a software called "Powermanager Lite" which is provided by Richcomm and supports Windows, Linux and UNIX. According to the manual it uses the Richcomm circuitry to talk to the computer and uses a drycontact protocol. Unfortunately I couldn't

And now for something completely different... :-) And yes, it's off-topic to this particular forum as it's not about NUT development. <ducking> Is there anyone around here who knows his way inside the hardware of an APC Smart-UPS? The APC support division will not reveal _any_ details or service information, and the only descriptive documentation I've found on the Web is in

Hi useRs, In trying to take R to engineering undergraduate students, I have been looking for context that would make R more accessible to the said audience. Though R is primarily a statistical tool, I would want to demonstrate the use of R for certain engineering courses (Design of Machine Elements - gear design, ball bearings, etc.) which would generate interest in it and provide students a way

This may be commonly known but I haven't come across it so here goes, maybe it'll help someone: I have terrible echo with asterisk 1.2, zaptel 1.2.12, and a TDM400P with 1 FXS and two FXO modules. The Mark2 echo canceller with Aggressive turned on was the only setting that would make it acceptable. I found fxotune with this zaptel version to be broken. I pulled the latest fxotune.c

I have an x100p which suffers from echo (no surprise there apparantly :), and a few of the things I've read about tuning out echo say the first thing to get right is the tx and rx gain, and for that you need a few different types of test lines from the telco (Telstra, Optus, whatever). Does anyone have any numbers in Australia for such lines? I think they just need to send out a tone of a

Hi There, i have a strange problem with a fenton powerpal 660. When you switch off the power to the UPS (from the wall), the server (IBM xSeries 203) attached to it dies...However, if you unplug the cable from the server to the UPS and plug it back in again (with the power still out to the UPS), the server starts up again (set to power up after a power failure) and runs with no issues. I have
