Bit coin links and Greg's presentation notes.

27 Jan '13

Hello All, Here is some more information from Greg's note at last Friday's presentation. I'd also like to thank Greg for volunteering to talk and for such a well presented and technical topic. Seeing the data miner in action was also a bonus. Attached is the email that Greg sent to Bruce and myself earlier this week. It seems as though there is plenty more reading on the topic. I've also loaded Greg's presentation to google docs so that those that weren't at the meeting can appreciate the presentation. <quote> Hi Chris, Bruce, as discussed here's the slideshow and talk-notes from last night I promised I'd send to you to forward on to relevant people, (group-wide bounced me on the email size limit).

26 Jun '11

There's a WLUG meeting tonight: ---------------------------------------------------------------------- Bitcoin http://www.bitcoin.org/ http://en.wikipedia.org/wiki/Bitcoin Bitcoin p2p monetary information technology: A demo for geeks & techies. Abstract: We begin with a brief historical background of monetary information technologies, digital currencies and p2p currency. Next is an introduction to the open source bitcoin protocol, block-chaining, the coin issuance algorithm, the recording and securing of transactions. After these preliminaries, the talk will be an open-floor format discussion with demonstrations. A short user-space demo of web wallet, bitcoin client and send/receive public key address usage will be given. Next we'll go "under the hood" and look at how the code and the network is functioning. Topics that can be covered include, but not limited to; location of significant files, configuration of the bitcoin.conf file, securing the private keys contained within wallet.dat file, running "bitcoind" on a linux machine with the command line query/response interface, building the code from source and alternate clients. Finally, we'll finish up with a demonstration of a 6 node GPU OpenCL GPGPU cluster, aka bitcoin "mining rig" in action.

Re: [wlug] Toshiba laptop
by Andreas Löf 25 Jun '11

Hey, You are basically running it already without a battery. Taking the battery out should not affect the operation of your laptop any further. If you take it out you can also look at it a bit more to determine the voltage of it. / Andreas John <jaytee(a)clear.net.nz> skrev: >Hi Noel >The advise I have been given is no cmos battery no boot but I am unsure >of the facts in that regard.The cmos battery has been dying for some >time as the rtc needed to be reset when ever I allowed the main battery >to go flat >There is a (10) battery available at Ebay but I was hoping for something >local. >Cheers John > > >On Fri, 2011-06-24 at 22:54 +1200, noel villamor wrote: >> John, >> >> I bought mine from Ebay.

Toshiba laptop
by John 24 Jun '11

Hi All, My old laptop just died and I strongly suspect the cmos battery. I wonder if it is possible to source one of these locally or manufacture something from the old battery that will do the trick. Link shows the thing in detail. http://www.zlectronic.com/product/CMOS-Li-ion-Battery-FOR-TOSHIBA-TECRA-S1-… Regards John

Need to make custom film cables
by Bryce Utting 12 Jun '11

12 Jun '11

Hiyas, I figure someone in Wlug might be able to point me in the direction of how to get this done (or have some nice fancy gear at work): I need a couple of board-to-board film cables printed; 1.5 mm spacing at one end (and thickened, to insert into a connector), and 2.625 mm spacing at the other (mated face-to-face with exposed traces at the end of a membrane circuit). Hand-painting the missing traces on the existing ones I've got just isn't cutting it, so I figure it's best to find someone who can screen-print this sort of thing. I have two different cable shapes, need three or four of each, and can provide PNG masks. Anyone able to help? ta, Bryce

Garage cleanout
by Daniel Lawson 11 Jun '11

11 Jun '11

Hi all I've got some boxes of old bits that I've hoarded over the years, that I now think I really need to get rid of. 2x HP Jetdirect EX Plus Printserver (10 Mbit RJ45 + BNC). No PSU for these, they'll need a 13C DC centre-positive psu. 3x 56k external modems. One is a 3com US Robotics, the other two are unbranded as far as I can tell. I may have a 4th modem somewhere as well, I can't recall right now There are two PSUs that probably go with these, one is a 12V 1A PSU, the other is a multi-voltage 3V-12V, 0.5A one. 2x speedtouch pro DSL routers, with PSUs. Both were working fine when I last used them, which was around 3 years ago. 1x Compaq Evo T20 thin-client + PSU, part # 238365-001. This is probably running WinNT embedded, but it can be reflashed to run linux. 300Mhz processor, 64MB flash, 128MB RAM (I think). I put some notes up at http://www.wlug.org.nz/CompaqEvoT20Notes about reflashing them, and I think I still have the CDs of tools that I used, which I'll put in with this. There's quite a few resources on the internet for reflashing these too, eg http://www.mowson.org/karl/evo_t20/ and http://open-evot20.sourceforge.net/wiki/ Industrial patch cables. 7 x 2m, RJ45 (8P8C) to XP85, and 2x2m XP85 to XP85. XP85 is basically a secure screw fitting around an RJ45/8P8C jack. It looks like this: http://www.alternetivo.cz/industrial-patch-cord-utp-xp85-to-mc5-1-5m-yellow… <http://www.alternetivo.cz/industrial-patch-cord-utp-xp85-to-mc5-1-5m-yellow…> A fairly pristine looking 3Com Ergo Audrey. (http://en.wikipedia.org/wiki/3Com_Audrey) This is a very early internet appliance (~2000), running QNX. It's missing a PSU, and I don't know what condition it's actually in as a result. New PSUs can be purchased from http://www.audreymadness.com/, (they're a fairly non-standard pinout and voltage supply). I also have some old Fibrechannel gear. One Emulex LP8000, which had current driver support (lpfc.ko) in debian lenny at least, and two Compaq Tachyon adapters, which show up on the bus, but don't seem to have active drivers since around 2.6.8. There's still 2.4 kernel support for them however. There's also a pair of Compaq Fibrechannel Hubs. Everything has optical modules, and there's a few fibre patches as well. A Sun Netra T100, missing disks and ram. The disks are standard SCSI SCA disks, but the RAM is harder to source - you need "Mezzanine modules", like these: http://www.memoryxsun.com/netrat1.html. I had actually ordered some for it at one point, but the seller managed to lose my order. Pretty sure this system also has a quad-port 10/100 NIC in it, but if you want the NIC, you take the whole lot. Finally, my old desktop. Athlon 1800+XP, 1GB of ram (I think), single SATA disk (80GB?), DVD writer. PSU was changed not long before I stopped using it. I can't recall what the graphics card in it is, but it's not super flash. Was working fine when I stopped using it. All the above is free to whoever wants them, you must pickup from Hillcrest area, or from the CBD during business hours. No guarantee that any of it works. If it doesn't go here, I'll either put it for $1 reserve on trademe or dump it.
