This is a very poorly researched article. They talk about getting 12V from a solar panel. No modern home-scale solar system runs at 12V. The power loss due to resistance is much too high until you use wires that are much too large.
The real solution would be to standardize on some type of home HVDC distribution in the 150-300VDC range. This would help keep the DC/DC conversion in roughly the 2:1 voltage ration range, which helps efficiency. It would also help keep the wire gauge reasonable. I'm not sure how the article's author envisions running things like a modern HE washing machine with build in heater from, say, 12V. It would take about 100-150 amps and require about 2/0 gauge wire to keep the losses manageable.
This is why I use a 39" 4k TV as my main monitor. It is like having 4x 1080p monitors but without the gaps between screens. It also lets you do exactly what this webpage is describing by using half your monitor.
Have you checked to see if you are sending unintended backscatter? You can get blacklisted by many hosts very fast if you are sending non-delivery reports (NDRs). In this day and age, you need to either reject the email while the connection is active (eg, user not found) or silently drop mail (eg spam that is filtered after the connection is ended). If you send NDRs after the email is acknowledged as received and ok, you are contributing to a significant backscatter problem.
I came here to post about MVNOs. I don't have any mod points, but this is definitely the way to go for single lines. I haven't used Black, but MVNOs are generally reasonable to deal with.
It's because your vacuum lies. That giant "18A" (or whatever) printed on the side is mostly marketing fluff. Also, even if it really does draw 18A, the duty cycle plays a big roll in the safety. Heating is a function of current and time. That's (one reason) why a lot of appliances say "household use only" -- the cord isn't sized heavy enough for high duty cycle use. That's part of why a 15A hair dryer can use 18 gauge lamp cord.
If you're handy, you can get amazing deals on full size business machines. I currently use a Ricoh Afficio 2238c for my heavy use work. It was $1000 and only needed about $200 in parts. It is 38ppm, color, duplexing, and can handle 11x17. It has an ADF and 11x17 flatbed which would be nice for the sheet music.
I pair that with an HP4100 dtn that is better for short runs and turns on faster. I have a 4600dn too, but don't really use it anymore. The older HPs are really a steal and have cheap aftermarket consumables.
I switched to tt-rss and couldn't be happier. It works almost exactly like Google Reader and even includes plugins to allow you to use the same navigation keys. It can import OPML for your feeds list and has a plugin to import your starred posts. The only downside is not being able to play flash video (youtube, et al) in the reader pane.
I had some fun with trying to mount some Crucial M4 drives in USB external enclosures. They kept getting unmounted and the SMART block remap count kept running up, and up, and up. One of the drives outright failed and the other was at 55% spare sectors remaining when I figured out the issue. When there was a write, the current consumption from programming the FLASH chip would cause a voltage sag and the write would fail but it wasn't usually enough of a drop to make the drive reset. Once I bought the "Y"-style USB cords (the kind with an extra power plug) and then modded that to run on a wall-wart, everything was fine. (Just for the record, this was a hack to add some faster storage to an aging server that only had SCA-hotswap bays).
I agree. The first time one of our engineer's laptops HD's did this, it was rather uncomfortable to say the least. I think a good compromise solution would be to have it enumerate with a "useful" drive textual model identifier like "M4 ERROR CHECKING, LEAVE ON 30 MIN" or some such. I'm sure it violates some standard, too, but it would at least give the user some indication of what is happening.
Overall, it is a good thing. The data isn't organized linearly for wear leveling purposes, so a power outage can leave the metadata in an inconsistent state. Also, make sure you have the latest firmware on the drive.
They had a fun one earlier that caused a drive lockup hourly after the power on counter hit about 35k hrs (or some such). I've got about 2 dz M4 drives in service, so I've seen a lot of the bugs.
There is a protection mechanism that I know exists in Crucial SSDs which makes the drive appear dead after some unclean shutdowns of the drive while it performs a firmware-level integrity check of the drive. It may exist in other brands as well. Sometimes it takes 2 runs of 30-60 minutes to get the drive to re-enumerate via SATA.
I'd be curious to know if the "dead" drive was affected by this bug.
I would recommend watching your SMART sector reallocation totals as an indication of drive health. As the drive starts aging, it will start needing to reallocate the weakest cells first, so you should get some warning.
I usually explain version control as working just like a library with a small twist. Imagine that this library holds paper notebooks that are partially used. You can go to the library, checkout a notebook, and write and erase parts of it while it is in your possession. Just like a library, if you have the original notebook, no one else can check it out -- you have exclusive rights to the notebook.
There is a bit of a twist that you can think of as working like an attentive librarian: every time the notebook is checked in, the librarian makes a complete copy and stores it in the reference section of the library. At any time, regardless of whether the original notebook is checked out, anyone can go to the reference section and read the reference copies of old versions. And, just like a regular library reference section, you cannot check those old copies out; they are read-only.
That's a lie. At least since Word 2003, there is a compare documents feature that you can use to make diffs of Word documents. Works fairly well unless someone really rototills a document with a ton of moves and rewriting.
My money is on it scraping your entire phone book so they can cold-call... Maybe someone should add normal-looking phonebook entries connected to some Google Voice numbers and record the hilarity?
I am deeply involved with party politics in my state. There is a deep need to get more technical people involved. Many friends I have talked to either "don't have the time" or think "it's so broken it can't be fixed". I say that the only reason it requires so much time and is so broken is precisely because normal everyday people aren't getting involved.
Politics takes time and energy, but it is run by those who show up. Please take time and get involved. I really couldn't care less which party you choose because the more people that get involved, the better the process will work. The SOPA fight was just the start. Let's get involved and show the world what this country can do.

Sorry for the self-reply -- one more thing. Yes, I know this is non-RFC compliant behavior, but it is essentially required these days.

Because you can pull 15A from one of them? The requirement for using 15A outlets on a 20A breaker is that there be more than one outlet.

Nevermind on the downside... Just found that there is a plugin to fix that.

With a spinning disk, the non-sequential access pattern will make the moving heads (and rotation rate) the limiting factor in throughput.

Stupid typos. The G and C are literally right next to each other*. Obviously this should be SourceForge.net.
*only applies to us Dvorak users.
Why bother with hijacking someone else system when you can just make a SourceForge project?
Just create a dummy SourceForce project. You don't actually have to attached any source files to use the bug tracker or other features.
