Where to find a software contractor?

by Andy Stewart

HI guys, I know a small businessman who is interested in potentially hiring somebody to write a piece of custom software. He is wondering where he would look to seek out contractors with the right credentials for this small project. He didn't mention too many details, but it sounds like the project will have something to do with bar code scanning, optical character recognition, and some type of graphical interface, most probably in a Windows environment. Where would you look if you were seeking a software professional on a short term contract basis?

IPv6

by William Smith

I read the powerpoint presentation that was posted here a short while ago and found it a bit helpful. I started setting up IPv6 on my home LAN last year. I got as far as setting up my Linux server to open a tunnel through SixXS. My ISP doesn't offer IPv6 quite yet, and even if they did, my firewall doesn't support it. That's why the tunnel. What I can't do yet is use IPv6 from other systems on my LAN. From the server, I can get almost anywhere I want to go using IPv6. Using the notes from the PPT presentation, I found out that I might have only STARTED setting it up. It looks like parts that should be there aren't, but I don't want to blindly set things without fully understanding what I'm messing with. I'm not sure if I have to put an address on the ethernet interface and set up a route or what. Any thoughts on what to watch for? -- Bill Smith Fall River, MA

second annual Northeast Linux Fest

by Jonathan Nadeau

Hello list Announcing the 2nd annual Northeast GNU/Linuxfest. Where: Worcester State University, Worcester MA When: March 17, 2012 Info: http://northeastlinuxfest.org Last year we had just speakers at the event. This year we are stepping it up considerably. We are featuring a hackerspace competition where teams from across the Northeast will compete for prizes for best design. This years theme is accessibility. We will also hold LPI and BSD exams on the morning of the event. The folks from Open Street Map will hold workshops throughout the day. We also have tables from various sponsors. Among the keynote speakers this year will be the other organizer for the event Jonathan Nadeau. Jonathan is blind but this has not prevented him from working with Debian, Fedora and Triquel in hopes of making each distribution more accessible for vision impaired or physically disabled. This is an event that can also be used to meet other people in the linux world and make new contacts. This is an all day event. All events will be held in the main student center. There is also a cafeteria on the second floor which features a $5 all you can eat buffet. Last but not least, if you are 21 or older we have our very popular after party event at Jillians. We also have arranged to get special room rates at the Worcester Marriott. You must reserve your room before February 17, 2012 to get this rate. You can either use the link off the Northeastlinuxfest website or you can make reservations over the phone but be sure to mention the Northeast Linuxfest group to get the rate. You can get to Worcester by train or bus if you do not have a ride. You can find that information on the website as well. We hope you can attend and most most important, the admission is free! The website again is http://northeastlinuxfest.org Take back control of your software, take back control of your computer! -- Jonathan Nadeau http://www.jnadeau.org Northeast GNU/Linux fest http://www.northeastlinuxfest.org

Re: [Wlug] Monitor resolution ...

Yep. It's the same sad situation as the birth of Winmodems. You can expect to only get the lowest common denominator junk, or to pay a premium for a vastly reduced selection of 'professional' monitors. There was a good XKCD that went something like: "Wow, 1080 lines! That's nearly _twice_ the vertical resolution of my phone!". I mean, it is a golden age if you want a really, really physically large monitor for a low price. If you really care about other specs though, you're out of luck, the wolves have voted with their wallets and you're what's for dinner.

Wow. Lot of work. Nice job on the work & the explanation.

Re: [Wlug] Acer Flat-screen monitor, needs repair, does anyone want?

by David P. Connell

And just for reference - not to dump on the company (if they even exist anymore!), all the electrolytics I removed from Liz's Acer monitor were from CapXon. And don't ask why I save them, but more than half the ones I have replaced have the same color scheme as these (green/gold writing). Maybe it is a rating (temperature, ramps up and down, etc.) I should know these things....and there are certainly what are considered 'premium' grade capacitors.

Re: [Wlug] Acer Flat-screen monitor, needs repair, does anyone want?

by David P. Connell

That was the only real issue with the whole thing - getting it apart blind. It ended up coming apart more like a cell phone than a monitor, by my experience. Once the stand is off, there is only one screw to remove, then its the trusty old guitar pick (secret tool of the cell phone/ipod industry) to remove the rear cover. Not required, but I also removed the whole screen and electronics modules from the rest of the plastics by removing 4 more screws - 2 on each side. The real difficulty, in order to make it look untouched, was that the power supply electronics and video inputs were under a steel cover that was fastened down with metalic tape, which I did not have in stock. I replaced by being careful and using some double-sided clear tape (Later). I slipped the button array circuit board loose from the frame and let it dangle carefully. I disconnected the output lines to the 'inverter/backlight/rest of the display electronics' which are dangerously exposed across the entire bottom of the screen, but fairly sturdy (double-sided tape?). This allowed me to move the unneeded parts well away from dropped tools, etc. Those connections were hard to disconnect, only because they are well-made and require some wiggling. I believe I left my mark most evidently there, especially since I numbered them and didn't bother to clean off the numbers. After doing one, I believe I could probably complete the process without anyone knowing I had been in there. Except....I used a totally different brand of capacitor with higher temperature ratings and the physical sizes were different as well. I matched the ratings otherwise. I guess I had to unplug those cable to remove the two boards to properly inspect and work on them. I guess there were 5 more screws there. And the video cable connector screws/nuts had to come off as they were holding that side of the small board into the cage. The heat sink was on the small board and itself was very small. The caps were all on the power supply board. It is made to be set up in several configurations. I didn't study whether that was for different models or just different caps. but I used the same positions as before, since the holes were left open from my de-soldering braid. The caps are all tacked down with a solid silicone-like substance. I used a matching almond silicone that is a little more rubbery, but still electronically neutral (enough). I finished cleaning up the dust with my trusty dollar brush, blew out everything with the canned air, and put it back together. It has been on ever since I finished and let the silicone dry for a while (hair dryer helped). It only just now exhibited a little bit of what I would call a 'hot chip', but I am definitely not a pro (I was an English Major), since there were a couple of black sections that remained until I passed the mouse over them. The Samsung I fixed a few months ago did that occasionally as well, but not very often, and then seem to stop, so I don't really know. If that is the only thing wrong, I will call it "useable" or "donateable" but maybe not "saleable". I know, I know, an English Major who makes up his own words....I enjoyed the time spent doing the repair, but if I charged what I make at my real job, it might come out pretty close to what I paid for this Acer 23" that I am using right now (which is why I bought it even after I repaired the Samsung - and like Liz and company - you have to have working tools to get your job done). Sorry for such a long message about hardware and nothing about Linux - hardware is more my strength these days.

Re: [Wlug] Monitor resolution ...

by Frank Sweetser

In the past, tv and monitors were two seperate products that shared some common underlying technology. Nowadays, they're just different market segments for the same product, differing mostly in the size, case, and marketing. Plus, since most HD content is recorded at a native resolution of 1080, watching it on a monitor with a physical resolution of 1080 (or multiple thereof) gives the best results. This is nice if you want to watch blue ray of HD streaming on you pc.

The general public has been trained that HD resolutions are the best, and LCD manufacturers get economy of scale by making TVs and monitors at 1080p ) On Jan 7, 2012 11:30 AM, "David Glaser" <dglaser(a)glaserresearch.net> wrote: > I was looking at monitors at WurstBuy and noticed that the maximum > vertical resolution is 1080 lines. > > I then looked at the sites of the various monitor manufacturers and also > noticed that almost all of their offerings has a maximum vertical > resolution of 1080 lines.

Monitor resolution ...

by David Glaser

I was looking at monitors at WurstBuy and noticed that the maximum vertical resolution is 1080 lines. I then looked at the sites of the various monitor manufacturers and also noticed that almost all of their offerings has a maximum vertical resolution of 1080 lines. You could get higher resolution but the prices are through the roof. Can anyone shed some light on the trend? -David

Re: [Wlug] Acer Flat-screen monitor, needs repair, does anyone want?

by Kieran O'Callaghan

The funny smell is usually from electrolyte leaking from bad capacitors. They were Abit ones affected by the so-called Capacitor Plague: http://en.wikipedia.org/wiki/Capacitor_plague There was an interesting industrial espionage story behind that where a Taiwanese was using an electrolyte formulation that was only partially recreated from a Japanese manufacturer. Continuing capacitor problems might be from that same formula still bouncing around, or they might be plain old heat problems, or simple under-engineering.

Re: [Wlug] Acer Flat-screen monitor, needs repair, does anyone want?

by E Johnson

Dave, Very glad to know that you managed to resurrect this thing. Meanwhile I am very happy with the new one. Thanks for the feedback on how you repaired this unit. Its twin here (not in warranty) is still running fine, but I can imagine I someday might have to deal with a similar problem in this one. I used to build & instect & troubleshoot small electronic devices, mainly little telemetry units for rockets, & mysterious black boxes for aircraft carriers. Except now I have no soldering tools any more. Anyway, mybe the dysfunctional heat sink was what caused the heat problem & early demise of the monitor. I now recall a "funny" smell right after the first blackout. Hopefully the heat sink on the remaining one here is glued on well enough. If the DH ever turns loose of Monitor 2 long enough, maybe we can take a look. Dave - How much disassembly is required before the heat sink is visible? Thanks again to everyone here.
