More activities have been added... Message-ID: <48c878f860fb16f8ed63548685c72510@sugar.utos.org> UTOSC 2009 is just one week away! The Utah Open Source Conference 2009 is starting just one week away, conference starts next Thursday, October 8, 2009! Several activities have been added that we'd like to tell you all about. We're sharing these because we believe will be of value to Salt Lake Linux Users Group. BSDA Certification Exam, The BSDA Certification Exam will be held from 1:45pm to 4:15pm on October 8 during Community Day. Exam information is available from the Certification page of the BSDCG website (http://www.bsdcertification.org/certification/) and you can read up about it on the UTOSC site by pointing your browser to http://2009.utosc.com/presentation/142/. The cost is $75 and arranged through the BSD folks. A new presentation has been added 'The Forgotten Edge: Building a Purpose-Centric Web' by Phil Windley which looks to be a very interesting look at identity online. Check out http://2009.utosc.com/presentation/147/ for more details. We have been able to secure space for six Local User Groups (LUGs) to meet during the conference on Oct 8. These LUG meetings are available to the public, so please come and attend. The following LUGs will be meeting at the times listed below: Greater Utah BSD User Group Meeting from 12:30-1:30 pm Salt Lake Linux User Group Meeting from 1:45-2:45 pm Provo Linux User Group Meeting from 3:00-400 pm Utah PHP User Group Meeting from 3:00-4:00 pm Utah Asterisk Users Group Meeting from 6:00-7:00 pm Utah Python User Group Meeting from 7:15-8:15pm More details about the LUG meetings can be found at http://2009.utosc.com/presentation/cat/19/ On Saturday, October 10 from 11:00-2:00 pm, we've added a BZFlag tournament during Family Day. Check out the details at http://2009.utosc.com/presentation/151/ for the rules and prizes. Don't forget Ignite Salt Lake starts Oct 8 at 7:15pm as well, it's free too, but you must register for a ticket to get in, space is running out quickly. Visit http://attend.utosc.com and register today. We have a promo code for Salt Lake Linux Users Group, good for 50% off the Full Access Pass.

I'm on several mailing lists, including ones from Network World, ComputerWorld, eWeek, and R&D magazines, the SANS security list, and ACM & IEEE technical bulletins. The ComputerWorld list is particularly useful: 10 to 30 stories a day in a compact easy-to-scan summary like the two-liner that I posted. For each of them, about twice a year I have to fill out a survey, which is somewhat of a nuisance, but the lists prove to be valuable, particularly when they describe newly-discovered security holes that need patching pronto. ------------------------------------------------------------------------------- - Nelson H.

Too early to tell. Right now, everything is delayed while I wear my managers hat and try to deal with severe systems problems. I'm on chapter 17 (of 25, plus a dozen appendices) of the last major readthrough, which also involves final tweaks on the million lines of underlying software.

It's been too long since I looked at the kernel process schedulers, but ... the real answer also depends on which process scheduler you are using. Some might not have felt the mentioning SLES 9/10 to matter, but it does, since different distributions might configure/patch their kernel builds to use different schedulers. How about Google? Or maybe look through the LKML archives. -- Lamont Peterson [ http://www.xmission.com/~lrp/ ] GPG Key fingerprint: C51E DD83 B03F D147 A974 939C 5D13 289C 17F1 FFBE -------------- next part -------------- A non-text attachment was scrubbed...

The idea is to make the interface exceedingly simple; most (if not all) of the user interaction will be done through beeping, speech synthesizers, and the bar code reader. It will be a mobile system, meaning that I plan on attaching it to some part of my body and running the system as I make deliveries and pickups. Due to these requirements, I want the core of the system to be a netbook. They provide the range of battery life that I need (especially if I keep the lid closed). I don't have to worry about using another system to program it, especially if I have a decent keyboard and monitor at headquarters. In addition, they're much cheaper than those programmable inventory jobs that I've seen in supermarkets and much easier to replace. My operating requirements don't call for a big, clear screen or even a nice keyboard. This eliminates most of the complaints of most netbooks. In turn, I think I can get away with getting the less popular (and less expensive) netbooks for my purpose. This means, however, that I am finding fewer customer reviews on the netbooks I'm considering up front. My request: What would you recommend given that all I need is a C/C++ compiler+IDE, USB ports, a sound card, and a rugged chassis? Would this work? http://www.geeks.com/details.asp?invtid=VIA-C7M1200-PB-R&cat=NBB I've also considered something like this, but I'd be jumping into unfamiliar territory: http://beagleboard.org/ Thanks! -- Andrew Jackman kd7nyq@gmail.com CONFIDENTIALITY NOTICE: This e-mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

Where I work now, we have successfully developed a huge data entry system based on a simple (transparent?) web interface with reasonable user-end requirements. I would go nuts with an Android. Unfortunately, the use of a portable, cheap end-client is that it relies on the assumption that internet access (or at least large area network) access be available, which it is not. I'm going to Peru to do all of this. At best, I can hope for some delayed transaction type stuff when delivery clients come back to base. Additionally, cell-phone service is not readily available, either, especially considering the sophisticated cell infrastructure that would be required to take advantage of an advanced cell-phone's features. I realize that a NETtop is designed for 24hr internet connectivity, but it's designed in such a way that it's still [near] optimal for this application. It's also only a first choice. I am beginning to look a lot harder at gumstix, for example. About 2/3 the price and MUCH smaller. Moreover, I don't think I can live without a development environment or a reasonably versatile interface. It saves me money to have a versatile, modular tool that can be field-programed, debugged, and used in unusual ways when something goes awry. Besides, I'd hate to think what'd happen if Peruvian sand got into that cute pearl mouse that works so well in the nice, clean United States of America... *winces* While not as important, a part of this is security. If a Peruvian can see it, he/she/it can steal it. A computer left at base is a computer stolen unless I can secure the base ($500?). More than $1000 in startup costs is nearly unheard of for a Peruvian business. Gumstix are super small and would be unrecognizable to a Peruvian, but would be harder to replace if stolen. Netbooks are more recognizable, but easier to replace. -- Andrew Jackman kd7nyq@gmail.com CONFIDENTIALITY NOTICE: This e-mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

A few years ago I saw a vendor that sold everything assembled, I can't find them now, but I'm sure there are plenty of others. The advantage to the net book is that it has the built in battery and you can use the screen and keyboard if you have to. I worry about their robustness for this purpose and also less usb ports for plugging in devices, which is a major issue with point of sale system. Some of the ITX enclosures come with lcd screens which might be handy. For something like this I would really lean towards the itx(just need to figure out how to make it battery powered).

Fedora 11 seems to think it supports PICs pretty well: https://fedoraproject.org/wiki/Packages_For_Embedded_Development I've used none of those tools, but PiKdev claims to be an IDE. In general, it appears C support for PICs is much less complete than for AVR devices. - Josh -------------- next part -------------- A non-text attachment was scrubbed...

When I was working on some PIC stuff a couple of years ago I got a pickit2 and I bought the CCS PCM compiler and just used everything in a windows XP VM. The USB support in vmware player was good enough for my pickit2 to work. I spent days looking for free options that would work, but in the end I paid $125 for my compiler (current price is now $150). When you buy a CCS compiler you don't just get a compiler. There is a complete set of libraries and accurate documentation. http://www.ccsinfo.com/content.php?page=Purchasing1 CCS also has linux command line compilers. If you can get your pickit2 to work in linux you can build and deploy everything on linux. Either way, I saved a lot of time by buying the CCS compiler. In fact, I doubt I would have produced binaries for my project if I was trying to cobble it together with what I found in the open source world. If you want a nice IDE that does pic and handles your programmer, I'm not going to hold my breath for it existing on linux. Just remember that virtualbox is your friend.

At the present, though, my PIC work is merely a small part of a much larger project and I was trying to keep it as simple as possible. There's a lot of more complicated design considerations that would be trivial to develop in PICBasic (What I'm using now) but I imagine would get pretty nasty in assembly. Theres a possibility I'll be stretching the speed of the chip, though, so I might be forced to learn assembly so I can optimize performance. Anyway, thanks for all the suggestions - that Fedora link is particularly useful. I was never able to find a summary list of all the available tools out there. -- Michael Heath On Wed, Oct 14, 2009 at 1:31 PM, Mike Bourgeous wrote: > Don't be afraid of learning PIC assembly.?

Pulseaudio is a "work in progres". It's a rework of esound which lost developer support. It was a royal pia when adobe decided to use pulse for flash and I had a school system running K12LTSP with no reasonable way to upgrade to pulseaudio on without a total rework of the thinclient portion of the server code. Ubuntu did a good job making it work. Fedora jumped a bit early. It really croaks on multi-user desktops. The first user gets sound and no one else does until they log out ( at least with the user-switcher process in gnome). I've done 4 or 5 F10->F11 auto-upgrades. They all worked before this one except for a x86_64 test rig that had been upgraded from F4 all the way to F10. By the time it got to F10 it was getting flakey. F11 pushed it over the edge :-) Time for a new drive anyway. I suspect that nautilus totally got hosed during the upgrade as my friend described what he saw and it didn't sound right when the system rebooted after the upgrade run (the whole anaconda process seemed to suddenly stop and reboot the system). Walked him through a command line create new user and then doing a gdm login as the new user. No joy. Login happened but no desktop icons and the topbar menus were hosed. Just prior to the upgrade I had to walk him through a yum reinstall of gvfs as an update seemed to break his desktop there. The trashcan disappeared and things went strange. He is in town for 3 more days (I think), out for a few and then back again for a week or so. Probably performing around the colleges (solo acoustic guitar - http://www.timbrelinemusic.com/home.html ). Any chance you could call him and take a look? If he could just get internet access I might be able to jump in remote but he uses a cell card and walking him through launching that from a command line is more than I can do.

There are actually several new Fedora Ambassadors in Utah and I think it might be a good opportunity to fix a problem and spread the love. As others have noted, pulseaudio is a problem for them, but we have not seen this issue. I will be meeting a bunch of friends from the Utah PHP User Group tonight at Applebees (105 E 12300 S, Draper, Utah 84020) from about 8-11pm. Look for me (http://opensourcebridge.org/system/photos/115/profile/IMG_0012.JPG?1237910371 a recent pic) at a large table and I can help your friend. If not, send me an email off-list and I will try to work out the details with you.

I believe the mods required would be worth the effort considering it's the lowest price of the bunch ($85). Still, I'm looking awfully hard at the Samsung devices because of they have /everything/ at a price less than that of the beagleboard ($110 vs $150). I am very attracted to the ARM platform due to the small size, power, linux support, and lack of power requirements (beagleboard runs on 5V/340mA). This means I can run the whole system on nearly any kind of electrical supply passed through a 5V/2W regulator. Rechargeable 9V batteries? Really the deciding factor is what kind of community support I can find for these systems. leopardboard and beagleboard have active IRC channels and healthy software projects.

As far as I can tell from reading many Web pages at this site, the compilers are built with gcc backends (and thus, can produce code for anything that gcc does), but have completely new language front ends that allow more powerful syntax checking, language translation, and rapid code development. There is a low-level virtual machine (LLVM) for which the compilers can generate code. There are graphs on the Web pages showing impressive speedups over gcc for front-end tasks, like syntax checks. On my GNU/Linux systems, I have these front ends installed: llvm-c++ llvm-cpp llvm-g++ llvm-gcc llvm-gccbug llvm-gcov llvm-gfortran Although C++ and Fortran are supported, the Web pages say that much work remains to be done for C++. On Mac OS X, I have clang, which doubles as a compiler and a syntax checker. ------------------------------------------------------------------------------- - Nelson H. F.

There was a contract for a representative licensing deal for releasing Unix versions. That's what made it so easy to dismiss the first case. Just because a couple of CEO's were ignorant about the details of contracts that subordinates hammered out, doesn't change the actual agreement which left patents and copyrights with Novell. from 2003: http://news.zdnet.co.uk/software/0,1000000121,2135637,00.htm Scott -------------- next part -------------- An HTML attachment was scrubbed...

Such systems can be of strong interest for massively-parallel independent workloads. As an example, a few months ago, I ran 128 simultaneous CPU-intensive jobs on one of our Sun Niagara processors (two 8-core CPUs, 128 hardware threads with one-cycle context switch time): these independent jobs normally run alone in 60 minutes with about 4MB of RMA, and all completed in parallel in less than 65 minutes while I was at lunch. ------------------------------------------------------------------------------- - Nelson H.

We?re going to try the three county geek lunch again since it seemed to work well last time we did it. The theme this month is ?Pizza? so come enjoy some gourmet pizza at ?The Pie Pizzeria?. Unfortunately, Utah County doesn?t have a Pie Pizzeria, so we?re going to substitute the Pizza Factory as a good alternate. Here?s the Details Meet at the nearest location to you at 12:30pm this Friday, October 30. If you have never been, look for the group with the 'Geek Lunch' logo at their table. We look forward to seeing all of you there.
