    What amazes me most is the failure to notice the modulation frequency and ti's phase lock to local power.

    Non inverter (all older) micrwaves use a 1/2 wave voltage doubler so the magnitron is only on for 1/2 the AC cycle. Google Microwave oven power supply to see a typical schematic.

    For unexpected frequencies, a non linerate in RF from arcing in the door seal can cause odd order harmonics. EG splattered food on the door seal area.

    Wow, Where are the old timers?

    One of the older viruses/malware would redirect dial up just to collect termination fees. This script mailware was most often associated with porn sites., but not always. The frequency of this exploit tended to die down with growing broadband use over dialup. I first saw issues of this with dial up modems. My early cure for this as a prevention was tu use an Actiontech Dual PC modem connected to a router in the same configuration as a broadband modem and router setup.

    This provided high immunity to the exploit as the modem contained the ISP dial up number and a compromised attack website could not log into the modem to change the numberr. As a network modem it did not respond to the Hayes AT command set.

    A common practice for ohters was to change the escape charactor, but this only provided limited protection as a changed configuration file for common dialer programs could still be altered. Hidden and Read only attributes in DOS addad another defence with limited success.

    Old school dial up was compromised by a very old attack against dial up modem use.

    They do need to be carefull if they try throtteling upstream bandwidth for customers with lower level packages. It is simply too easy to prove. Comcast is an example of where this was not hidden very well. Customers with 20Meg Comcast connecitons could not stream Netflix nearly as well as 6Meg DSL customers in the same neighborhood. Customers needing redundancy against outages were the very first to note and document the problem.

    Verizon needs to be carefull what is placed in their sales training materials as this could come back to bite them.

    Since multiple sales agents have called using the same sales script, this could indicate a problem in the sales management team.

    I do agree that someone is trying to sell something.

    Unless entire large acrage farms convert into solar, the distribution of retail, commercial refrigeration, high density housing (apartments), etc will notmeet daytime demand. Many businesses have installed some solar to offset their daytime energy use.

    Most home solar installations are supplimental with only brief periods where the het pump cycles off durring the day that net metering even feeds into the grid.

    In my area I have looked into the possibility of off grid, and it would require removal of the laundry pair for hand wash instead and an outside clothsline in all weather.

    If I covered my entire roof, I would have to change my primary heating to something not dependant on electric. Yes I could possibly sell some daytime power to the utility for a couple of hours each day, but that small amount an more would be consumed by the supermarket down the street. The utility would never have a net surplus from consumers that is not used locally.

    They are committed when it impacts large contracts.

    Seen stuff in the news lately regarding the push for open document standards on the web? Governments are now specifying published government documents can not be propriety formatted. This forced Microsoft to support open formats or lose large contracts because Microsoft Office is not meeting specifications of the document requirements.

    Compatibility with internet standards has forced open standards onto Microsoft for a long time from TCP/IP over NetBios, to NTP, Remember when Microsoft had Windows for Workgroups? The Internet put them at risk of a end run past them. They had to adapt or die.

    There are numerous other examples where Microsoft does not own the standard in use where their solution was forced to the back to die.

  8. Re:Free advertising on Legislation Would Force Radio Stations To Pay Royalties · · Score: 2

    I think the radio stations should start charging labels for airplay advertising to recoup the increased cost of program material. Advertising is already starving radio stations as media is moving online. About the only ones listening to over the air radio anymore is commuters trying to wake up and catch the traffic report. Now that Google Maps has added the real time traffic overlay on maps, even that is going away as people use a cell GPS to avoid traffic gridlock.

    How many homes no longer have a home stereo system with a radio turner? It's video at home or online streaming to cut the 10 song loop may stations play. Dilute that with an over stuffed advertising bundle and you see the problem. Even on weekends, many radio stations pretty much shut down operations and play infomercials to kill time normal advertisers wont support enough to keep the lights on.

    If you are a radio station, your prime time audience is only from 6-9 AM and 3-6PM. Everything else is repeat programming.

    In addition to the click, the key then requires less force to bottom out providing positive tactile reinforcement the key hit home.

    The biggest issue on rubber keys is not punding them hard enough so I have missing letters on a regular basis. For example the line I just typed. I am not going to edit it for the missing letter as I am typing on my laptop. The remainder of the red lines I did correct so one error is not a typical keyboard induced typo. In reality it is much more. Re-typing requires extra time, mental process, and distracts from work, so a good keyboard does improve productivity and accuracy.

    My Keyboard of choice is the IBM Model M hands down. For ergonomics, the tactile feedback is perfect with less proofreading required. The dish shape over a flat keyboard is a huge ergo win and preferred above split keyboards. Did I mention I hate flat keyboards? The key caps are dished and reduced in size so centering your fingers on the keys is natural, unlike square flat keys created by some artsy creative designer. Laptops often favor the square keys as there is less room for dirt and crumbs to fall between the keys. Unfortunately, for a touch typist, getting off center and pressing double keys is a common problem.

    Look for a keyboard that you can feel it has made the stroke by feel and the screen really shows the output. Some rubber keyboards do buckle and appear to have bottomed, but still fail to register a key press. Look for one with dimples in the keys so the fingers naturally settle into the centers. and last find one that is NOT FLAT, but curved so you don't have to reach for numbers etc.

    Avoid keyboards with extra keys resulting in a small return key. Hitting extra keys that are where you normally have the return key is bad. Having an extra long reach to hit is is an ergonomic issue.

    Did I plug the IBM Model M? One without the Windows key is Ideal if you can find one.

    Forget the lot. Look at the cars. An empty lot at dinner time is a sign a table is waiting, but you don't want it.

    Info can be found on Falcon Christmas regarding the Falcon Pi Player.

    Workflow is not bad. Use Vixen to create a sequence in time to a song. Normally this is the end as you can play the sequence and music and output to the lights and FM transmitter. This has two issues. Nobody wants to leave the laptop outside to run the show, or run very long cables from the show computer to the display. Besides it ties up the laptop.

    Once you have a sequence saved, it can be imported to Xlights/Nutcracker. You can add Nutcracker effects if desired. It has some neat effects for a mega tree pixel matrix. The sequence is then exported in a format compatible with Falcon Pi Player.

    Falcon Pi Player has a web interface. Link with Ethernet using wire or wired. Who cares? Either works. Upload the music and sequences to the player. Set the clock or let it use NTP on the web. Either works. Raspberry Pi does not come with a real time clock, so clock setting is required to schedule shows. Schedule your shows (playlists) and the Falcon Pi Player will run the entire show on schedule. Output to control the lights can use any of several compatible interfaces including a DMX Dongle such as an Open DMX USB, or equivilant, or for larger shows spanning many universes of DMX and driving LED Pixels, one of the SansDevices E1.31 interfaces or the DIYLEDExpress E1.31 bridge work great. SanDevices are compatible with more varieties of LED pixes and DMX. Input is Artnet or E1.31. DIYLED Express outputs only two popular LED formats and DMX and only does E1.31 input. I use the DIYLEDExpress bridge to drive a mix of LED's using WS2811 chips (very popular) and DMX devices. Falcon Pi Player does not do Artnet, so Artnet on the SanDevices items are only useful if you want to use FreeStyler and output Artnet. Freestyler does not output E1.31 yet, so that software package is incompatible with the DMX Bridge from DIYLEDExpress.

    Hope this helps.

  15. I found the Google results often cherry pick. When looking for a Chinese restaurant for example, Google will show one, but on the way to it I pass 5 others. Correction, I passed 5 and took the sixth instead of making it to the one listed in Google. I sometimes do a search to find a cluster of restaurants and then do a sidewalk and parking lot search. Local knowledge is often better than placed ratings as they are often gamed. A good parking lot is a good indication. Good locations with a good local following are often not even interested in online reviews and map placement to prevent overcrowding. How many online reviews suffer from poor customer service, long lines, long wait times, etc. Find places not on Google maps.

    When you look at developers, the lower price points for the Pi has produced some excellent applications. After seeing the Pi put to use to run an entire animated Christmas Light Show, I bought a Pi B+.

    Sometimes your purchase decisions are based on finding the application you want to run and then buying the hardware that will run it.

    If you are into synchronized Christmas light displays on a budget, you can't beat a mix of Vixen, X Lights/Nutcracker for content creation and loaded on a Raspberry for scheduling and playback.

    My setup is using addressable LED pixel strings, Falcon Pi Player on a Raspberry, connected to a DYILEDExpress DMX Bridge using e1.31 protocol. The entire control hardware is under $150 in hardware. Only major expense is buying LED lights which scales with your display size.
