  1.   Wow. I can't even imagine how nasty and dangerous the cleanup operation must have been!
  2. Thanks, never heard that story before.   The article says the criticality lasted 20 minutes or something. Do you know how they sqelched it? Something like pump part of the HEU out of the barrel?   Or did it just melt out of the barrel and then disperse on the floor or something?
  3. One thing I liked was all the "oddball characters" in the show. And that nobody had acceptable body hygiene except matt and maybe kitty. Most folks walked around covered in months of grime. Matt probably didn't have to worry about getting snuck up on, because he could probably smell em from the next county over.
  4.   East St Louis was a mess when I lived in the outlying burbs of that vicinity, as a kid in the late 1950's.    Maybe historical research would be useful to discover in what historical era that East St Louis first began to suck? Surely it wasn't intentionally designed to be a hellhole beginning from the first moment of its founding?   When we lived in IL, old dad oft expressed a theory which he probably did not routinely divulge to natives-- According to dad-- In the pioneering days, the smart people stayed on the east coast, and the brave people moved to the west coast. The people neither smart enough to stay east nor brave enough to move west, stopped half-way  and settled the St Louis area. :)
  5.   If all a gadget needs internally happens to be 5 V then probably not a problem with a single battery, even with analog voltage regulators. Ferinstance, the 7805 spec sheet claims that input voltage needs to be >= 7.5 V to maintain regulation. If a 12 volt battery has been drained down that low, then the poor battery might possibly have permanently gone to heaven for its just rewards. :)   I'm so out of date, dunno what folks use nowadays. Dunno the capability of cheap off the shelf new components.   Was thinking of the situation of building a regulator to knock down dual series batteries to 12 volts. I just recall with old analog regulators such as 78xx it was wise to avoid too much of a voltage drop. For instance, with 78xx, if you need 5 V and all ya got is 30 V, you better not need very many milliamps or that sucka gonna get hot!
  6. On OOKLA Speedtest, EPB Fiber Optics at my house, today about 3 pm--   Ping: 14 ms Download: 94.06 Mbps Upload: 94.43 Mbps
  7.   Thanks, that is a good point re just using a small always-on smart charger and a deep cycle battery. A possible complication, or alternately I'm overthinking it-- Something on the order of 13.3 V is nominal full-charged car batt. It is doubtful that 13.3 volts (or whatever) would be too high a voltage for typical 12 V computer devices, as they have voltage regulators inside them. However, if the power goes out and the battery has run long enough to sag to 11 volts or lower-- Dunno how low the input voltage could sag and still keep happy a router or a hard drive enclosure? Also perhaps it needs some kind of auto-shutoff feature, because even a tiny constant load can damage a perfectly good battery if you drain it below a certain percentage.   What little I used to know is obsolete. Maybe the little gadgets use little active digital DC-DC converter regulators nowadays. By the year 2014 maybe such gadgets can boost-buck the DC power input? Dunno.   If the gadgets use old-style analog voltage regulators-- Those old analog regulators can't boost, and the inputs need a few volts "comfort level" above the regulated voltage output, in order to function properly. On the other hand, a decent inverter ought to deliver about the same "equivalent AC voltage" as the battery discharges, until it finally auto-shuts-down to protect the battery. I don't recall reading complaints that inverter output voltage will sag along with battery voltage, but maybe some do sag. Dunno.   Perhaps a long term direct 12 V DC backup for a router, would use a couple of 12 V batts in series or whatever. Deliver 24 (26.6) volts, and then build a little voltage regulator box between the battery and the router? Thataway the router or hard drives would get exactly 12 volts all the way down the battery discharge cycle?   In principle such a circuit ought to be simple and cheap to build. In practice, it might require more thought. Analog voltage regulators-- For instance 24 volts in, 12 volts out-- They heat up just like a resistor dropping current. To maximize efficiency and reduce heating, it is best to have the input voltage "just enough" higher than the output voltage to assure proper regulation. Excessive input voltage gets dumped as heat, which would waste battery power and also perhaps require something a little fancier than the simplest cheapest circuit. For instance, 24 volts in, 12 volts out, 100 ma draw-- The difference between 24 volts and 12 volts gets converted to heat like a power resistor dumping current. As best I recall watts = volts * amps, so the 12 volt drop across an analog regulator would generate at least 1.2 watts waste heat.   My seagate 4 TB external, the drive enclosure doesn't spec the current draw, but its little transformer is rated at 12 volts, 1.5 amps. If drawing 1.5 amps, the regulation waste heat would be 18 watts!! So a little 24 V to 12 V regulator might need building as a digital regulator of some kind, to avoid the regulator draining battery power as much or more than the gadgets?     Maybe some day, but I've got purt stupid in my old age, and barely manage to program part time lately. Batting at geese with a rake!
  8.   If only that were so! :)   edit: Since I started using UPS on all the puter gear, the incidence of mysterious computer crashes "out of the blue" have reduced to zilch. Modern OS don't crash so much anyway, but I started using UPS back in Win98 era. It even cleared up most of the Win98 crashes I was getting. Giving indirect evidence that a certain percentage of "out of the blue" crashes are due to nasty power.
  9.   Am not arguing, merely adding $0.02-- The working innards of telephone exchanges may be different nowadays, but from the very beginning until at least not very long ago, the primary power supply for telephone exchanges was HUGE DC battery banks, and the AC power was used to keep the battery banks up. That is because the system was designed to run on that DC on the lines. So if the AC failed but there wasn't anything wrong with the phone net, then the phones would stay up until the battery banks would discharge. And as you mentioned, they usually had backup power to charge the batteries.   Maybe nowadays they have figgered a way to finally get rid of the humongous battery bank, but that was the situation for what, 100 years or more? When did they start installing phone nets?   I'm a big believer in UPS boxes. Have several, on all the equipment I consider "essential". For a couple of years APC has been selling a smallish UPS designed specifically to keep home modems and routers alive, "quasi long term".   Many consumer UPS are designed to keep up a desktop computer, supplying a fairly good current for a relatively short time. Such UPS's will run much longer if lightly loaded, but I suspect the fairly big inverters drain the batteries quicker than necessary when running at very small loads. In the storms a couple years ago, my APC back-ups 1500's would run trivially small loads 2 or 3 hours apiece before running down the batt and shutting off, though the runtime is MUCH shorter for running a desktop and monitors.   But MAYBE if designed correctly, a UPS specifically designed for the low power draw of a router and modem, could run longer. Dunno if that APC model fits the bill, or if it is just a re-branded low-power UPS, trying to get more sales with a specific advertised use. I usually have run my router on a small shoebox sized ups, because it is all by its lonely in another part of the house from the puters. Was tempted to get one of those home-router-specific UPS at best buy, but have so far resisted the temptation. Well, my initial temptation was when I wanted to exploit the NAS feature of my linksys router by attaching a big hard drive to it, and you would definitely want a UPS on the NAS. But then I discovered that the NAS features in my model of linksys router don't work worth a crap, though the router itself works fine for my uses.
  10. Sorry, sounds painful.   Though you most likely can't profitably sue yerself for spilling hot coffee, maybe you can sue the coffee pot mfgr. Or possibly you could sue yourself then the house insurance would have to settle for a large sum to cover your accident liability to yourself! Including extra sums for pain and suffering and negligence. (just being silly)
  11.   I don't know one way or t'other, but think they show different burn rates on burn rate charts, unless the color of the dots controls burn rate? Or for all I know maybe they might adjust burn rate of the same base composition by changing the grain size? Am real ignorant.   Just thought I could look up on the internet whether it is flake or ball or whatever, but yesterday couldn't find that explicitly mentioned in manufacturer data.
  12. If I had no other choice but to use comcast to access the interwebz, then I would give up the interwebz.
  13. Long ago, was on the road playing a club in Galesburg IL of all places, and the sign said, "Out of my way, I've got to drain this beast!"
  14. What shape is blue dot anyway? I can't find that datum on the interwebz today, and too lazy to go out to the shop and eyeball some with a jewellers loupe.   Ramshot says zip and sillhouette are-- "double-based, spherical-shaped, smokeless powders"   Those three are about all I ever use lately, and all seem to meter ok in the dillon powder measures. I'm not an authority and don't use those powders because they are anything special. Just that they work good enough and I don't want to hassle with changing powders and then working up new loads.   CZ if you ever get in the redbank vicinity I could give you a few ounces of those to try.   The zip is low volume economical for plinker loads. Said to be identical to W231. Because the typical load is light, it would be most subject to errors in the powder measure.   I've not used blue dot on 9mm but its supposed to be good for medium to hot 9mm loads and would probably fill the case more than the other two, possibly minimizing powder measure variability if your measure drops it ok. It is also a hoot to shoot on cloudy days or near dark because it makes a huge fireball.   The sillhouette is higher volume than zip, most likely lower volume than blue dot. It is good for medium to scalding 9mm loads, and is what I've been using mostly on 9mm for several years.
  15. Companies have the right to set selling policies within certain regulatory bounds of which I'm woefully ignorant. On the other hand, in some situations have seen in other markets, non gun markets, franchises appeared to be non-competitive and lead to "unnecessarily high" prices and limitations for customers.   So, though it is the company's biz within legal bounds to set sales policies, if this is a franchise squabble then it is difficult to get too scandalized over it. Maybe "breaking the rules" led to lower prices for some consumers?   OTOH, companies seem to get bent out of shape about employees skimming off the top, on the theory that if skimming is to be done then that money belongs to the company and not the employee. A round about method of theft that the company might prefer charges over?
