I've seen HAM radio at it's best, and how it can be taken out by any idiot with enough broadcast power. I was in Puerto Rico when a bad hurricane hit the island and wiped out all communications over most of the island. A good friend was a HAM operator, and he linked up with a semi-formal network of HAM operators along the east coast that activates whenever there's a hurricane disaster. These people provided the only communications for large numbers of people for several days, and were instrumental in saving lives. At one point, however, one pin-headed yokel got on the frequency the net was using and rebroadcast AM radio music with a lot of watts behind it. They finally got this guy off the air (with some FCC help), but he hindered the net for almost a day.

The HAM community does a lot for many others who are not HAMs, and to open their bands up to individuals who only see dollar signs everywhere and only think of their own "rights" to do whatever they damn well please would be both a travesty and a serious mistake.

Saw this take on one of the tinfoilhatcrazy websites. Snowden is a deep US CIA agent with the task of getting close to Wikileaks and Julian Assange in order to either get Assange out where he can be arrested or make a hit. Sadly, this makes as much sense as anything else - right up there with the "impress the girlfriend" view.

Simply put, they stick around because it's a good-paying job in an economy where there aren't that many available. Your friend bailed 10 years ago, back when jobs for people in these fields were a lot more plentiful. NASA became a giant jobs-and-pork operation years ago, and was one of the original "welfare for whitecoats" agencies (whitecoats as in lab coats). Any engineer or scientist with a NASA job these days hangs on as long as they can. Mortgages gotta be paid, and kids gotta be fed.

I am a long-time bleeding-heart liberal type, and while I am aghast at what we’ve given up in the name of The War on Terrorism I can see the usefulness, and perhaps even the imperative, for the US to collect and analyze data of this sort. If, and a very important if, the use of the data is carefully monitored by third parties and there are clear guidelines for collection, protection, and use of the data. Back in the Good Old Days of the 20th Century enemies were spatially located (for the most part). Spy satellites and spy boots-on-the-ground could be and were used to keep track of what people who wanted to do us harm were up to (in theory, anyway). These could also be used on US citizens, and there were pretty clear rules about not doing so (rules that were, admittedly, overlooked or circumvented at times). These days, the people who need to be watched are all over the world and are best tracked via lines of communication, most importantly cell phone and internet technologies. That’s what this is all about, keeping track of what’s going on so there are few surprises like the 9/11 fiasco.

Now, can this be misused? You betcha it can. Faster than you can say Nixon (or your favorite Bad Guy’s name). However, to NOT collect and analyze these data is a bad idea as well. As always, there’s no perfect solution. I think those data need to be collected and analyzed to keep an eye on what’s happening, but we also need more transparency on the checks-and-balances put in place to make sure the data are used only for very clear purposes. Can this be done in today’s highly politicized, the-other-side-is-stupid, political environment? I don’t know, but I do think we need to try.

Things that caught my eye were (1) iCloud keychain to allow better mobile-system tracking of passwords within the iOS and OS X framework, (2) iBooks on Mac (FINALLY!), (3) some expanded multitasking in iOS 7 (although it's not clear if it's really extended capabilities over iOS 6 or just a spiffier UI), and (4) Airdrop from within iOS 7 to nearby devices. The new Mac Pro line looks sharp, and I definitely lust for one even if I don't need one.

I agree completely about science running mostly on *nix for heavy lifting, but what about desktop? I have given up on the Linux desktop for reasons stated by others in this thread, and use OS X for my desktop. Unfortunately, OS X has been trending towards becoming iOS on the desktop, which I hate, so I've looking at (shudder) Windows 7. If MS hadn't biffed so badly on Windows 8 (making the same mistake Apple appears to be making, trying to make the desktop look and act like a big cellphone) I'd be seriously looking at a Windows desktop (still with *nix doing the heavy lifting).

Is "safe online (PUT YOUR SERVICE HERE)" as much an oxymoron as the much-malinged "military intellegence" back in the '60s? I see lots of stories about both sides of online voting, but I've not seen an answer to the basic question of "is it possible to have a safe hack-proof online voting system." I don't mean an assessment of whether Siebold or any of the other idiots in this market have fool-proof systems, but whether or not voting can be done safely online even if Brother Stallman designed it. My own feeling is that it's like putting something critical such as access to power grids online - not a good idea unless there's no other way to get what you need. I don't really see what's so hard about schlepping down to your local school and voting once a year or so. If that's too hard for you, don't bother voting because the hard work of making an informed choice is likely beyond your capabilities as well. (Does not apply to people who can't get to a voting booth for several of many good reasons, and mail-in ballots has worked for these people for decades.)

Started with punch-card (not IBM format) programming a Wang desktop beast, hand-inserting one card at a time. Rebooting (which was needed more often than I care to admit) required walking down the hall to the closet where the "brains" of the thing lived. I then graduated to a PDP-8 that was sitting in a corner waiting to be installed for a remote-access telescope, programming by entering Basic commands via a TTY. Finally they let me at the observatory's new CDC 6600, reading data from paper tapes (down from the mountain) and programs from punch-card decks. That's when I learned Fortran (II), which is still my main language. I also had to walk 12 miles to work in the snow every day (in Tucson). The alternative was to wait for the stage coach.

This really makes me feel like retiring! I worked at the USAF Global Weather Center (AFGWC) near Omaha in the 1970s where there was this mysterious computer referred to as a TIP which plugged into an even more mysterious ARPANET thing. We'd hang 9-track tapes and ship data back to research and archive centers on the east coast once a day. As a 2nd LT my time was deemed cheap enough to spend babysitting the transfer process (which often broke down). Time flies when you're on the 'net.

Ok, just looking at water for a four-person household you're at something on the order of 600 gallons of water for 30 days (5gal/day times 4 people times 30 days). That's 120 of those 5-gallon jugs that sit on top of office water coolers. A bit more than "closet space" unless you live in a megamansion. Storage of enough water, and the periodic recycling of the water store, is probably the biggest headache for going past a few days for most people.

Keuffel and Esser (K+E) have just announced their new electronic, cloud-accessible slide rule. Made of recycled circuit boards and faced with titanium recycled from old Soviet submarines, these babies can do just about anything with at least three-digit accuracy. Give-or-take a power of 10.

This is how Government funding works. I was at a workshop on the then-new field of space weather forecasting in the mid 1990s where the keynote address was given by Dr. Joe Friday, at the time the head of the NWS. He pointed out that we would see no serious funding from Congress until there was the space-weather equivalent of a train wreck that kills many voters, or costs the monied interests lots of dinero. (Joe later lost his job when a non-forecastable flood in the mid-west that exceeded the 100-year flood levels wasn't correctly forecast. In this case, the solution was of the Shoot the Messenger variety since the real cause of the bad flooding was lousy planning by the Corps of Engineers.) The local government version of this is not putting a stoplight at a bad intersection until someone, preferably a cute child or pregnant mother, is killed there.
