  1. Re:Wow... on More Schools Go To 4-Day Week To Cut Costs · · Score: 1

    It seems an especially false economy because it is rather hard to "close" a school(or any other largish building, particularly in a cold climate, that is actively used much of the time) for short periods.

    You can lock the doors and hang a "closed" sign, sure; but you've got to heat the place to keep the pipes from freezing, if in winter, there will likely be some lights you need to keep on, custodial and other support staff may need access to run around and do their thing, IT will want computers on to do patches(and probably won't ever want switch or server racks to be off...)

    It just isn't trivial to turn a building on a dime(especially if it is an older unit with slightly cranky or inflexible climate control systems).

    And, of course, beyond the material consideration, team finance would probably like to have a word or two with you about the opportunity costs, depreciation costs, and assorted other quantifications of the fact that letting useful stuff just sit there has downsides...

  5. Re:Amazing... on 5.8 Earthquake Hits East Coast of the US · · Score: 1

    Also, why on Earth would they evacuate the Pentagon AFTER the earthquake? Does that make any sense at all?

    I'd sort of hope that the Pentagon would be built to better standards than that; but I can think of one reason you might evacuate after a quake: If the shaking cracked/sheared any gas lines, you could theoretically end up with a delightsome fuel-air situation in part of the building. In that case, you'd want the herd out of the building before the situation deteriorates.

    With stronger quakes, or shoddier buildings, it isn't unheard of for buildings that don't collapse immediately to do so during the aftershocks, in which case you would prefer to be outside as well.(Again, though, serious risk of collapse in the face of a 5.8 should be a breach of any decent building code, much less the standards that you'd want your giant military headquarters/symbolic structure built to...)

  6. Re:felt it in NYC on 5.8 Earthquake Hits East Coast of the US · · Score: 1

    I felt it in upper Manhattan. The building did a slight sway back and forth. First time I ever experience that. But Manhattan land is on solid bedrock, how could the quake effect reach here?

    That's exactly how. Earthquakes travel from their epicenter by wave propagation. A nice, dense, more-or-less-continuous medium is perfect for that. If you were in a largish building, the building was probably even resting on/coupled with the bedrock to keep it from shifting in the dirt above. A tuning fork welded to a beam, and somebody hitting the far end with a sledgehammer...

    Unstable media can be dangerous in earthquakes, because they have the nasty habit of exhibiting liquefaction; but solid media transmit the waves quite well.

  7. Eh? on Using Tablets Becoming Popular Bathroom Activity · · Score: 2

    "And in a data point sure to further damage techies' reputation for social skills, Staples Advantage also reported that 30% of tablet users said they used their tablets while at restaurants."

    I'm not sure that the techies will be atypically hard hit by this one. Back in the day, when obsessive computer use required an obsessive interest in gaming and/or some techie esoterica, and it was cost-prohibitive to compute on the move(much less get internet access...), the techie social skills reputation was not exactly bolstered by the tendency to stay inside and play with their computers.

    Then came the mass adoption of laptops and blackberries by practically every 'road warrior' type suit with a salary high enough that paying for the ability to bug him while he was away from the office made sense. This certainly did include some techies; but the population of management/sales types brandishing their blackberries and monopolizing flat surfaces absolutely exploded.

    Now, with cellphones falling well into affordable for all but the most squalid, and Apple having WAFed the hell out of portable computing, it sure isn't techies who I see logging the most socially inappropriate screen time...

  8. Diff? on Zombie Cookies Just Won't Die · · Score: 1

    Please correct me if I am wrong on this; but it would seem that, in principle, it would be quite tractable to generate a 'local persistence profile' tracing the activity generated by loading a URL as a series of addition, deletion, and modification operations to the state that existed before the URL was loaded(in the same way the various browsers' dev tools allow you to trace the network activity and script execution associated with loading a URL). With that, the user would have broad power(limited largely by their desire not to wade through a massively complex interface) to immediately roll back all changes made on exit, on leaving the site, or on some schedule. Wrapping that in an interface simple enough to be used and powerful enough to be useful would be a bit tricky; but you'd have an extremely granular revision-control style record to work with, which would make adding a few basic features comparatively simple(ie. "All changes that occur when running in Porn Mode are reverted on exit" or "all changes that occur when I load evil.com are reverted when I navigate away from evil.com".)

    It would even be doable, probably through the use of site-specific addons developed by the knowledgable, to selectively roll back certain changes but not others(ie. if webmailfoo writes a cache of my last 30 days of email to a local store, I don't want to roll that back; but I do want to roll back the changes made by the fooad network...) or even to programmatically modify locally stored data(that aren't cryptographically signed, or otherwise protected from any tampering other than deletion...)

    The local threat certainly isn't getting any easier or less complex; but it is, at least, a software problem. It's the remote threat that you really have to worry about. Covering your tracks against a reasonably smart remote agent turns out to be pretty difficult, and you can't(legally) just go and purge their systems.

    As best I can tell, after going back and reading the paper, TFA is a miserable hatchetjob that has almost nothing to do with the paper.

    The paper dealt with modeling the survival or culling of protocols at various layers, under various selection criteria, from a sort of evolutionary-biology standpoint. This did entail examining what conditions resulted in monoculture end states, and what conditions might result in stable multiple-protocols-at-each-layer end states; but all at the level of a fairly abstract model, not an empirical examination of the State of The Intertubes, or much specifically security-related material(In TFA's defense, the paper did suggest that, if you wanted a stable-state outcome with multiple middle layer protocols, they would have to be non-overlapping, which TFA managed to at least parrot accurately, and both agree that the internet as it exists is pretty much an IP monoculture; but the two otherwise bear surprisingly little resemblance to one another.)

  11. Unstated, and important, assumptions? on GA Tech: Internet's Mid-Layers Vulnerable To Attack · · Score: 4, Insightful

    There seems to be the unstated(but vital to the conclusion asserted) assumption that competition actually makes protocols more secure and that competition must occur at the protocol level, rather than the implementation level. Without those assumptions holding, all this article really says is that people use TCP and UDP a lot. Yup. That they do.

    This seems like it might be true in the (not necessarily all that common) case of a protocol whose security is fucked-by-design competing with a protocol that isn't fundamentally flawed, in a marketplace with buyers who place a premium on security, rather than price, features, time-to-market, etc.

    Outside of that, though, much of the competition and security polishing seems to be at the level of competing implementations of the same protocols(and, particularly in the case of very complex ones, the de-facto modification of the protocol by abandonment of its weirder historical features). It also often seems to be the case that(unless you are in the very small formally-proven-systems-written-in-Ada market, or something of that sort) v1.0 of snazzynewprotocol is a bit of a clusterfuck, and is available in only a single implementation, also highly dubious, while the old standbys have been polished considerably and have a number of implementations available...

    I'd be curious to know how much of that is specifically tied to cost cutting/outsourcing and how much is tied to the rise of "easy adequacy" in computer specs...

    Dell's stateside 'manufacturing' capability has(at least for a long while now, if not always) been assembly of components from elsewhere into final machines. This allowed them to achieve extremely fast turnaround for more or less any combination of modular parts were supported by a given chassis type. They weren't making custom motherboards, or fabricating cases from sheet metal and injection moulding feedstocks; but they could slap pretty much any combination of CPU/RAM/HDD/PCI/PCIe/PCI-X option cards into your choice of chassis, and have it shipped from a domestic location within a day or two.

    However, it isn't clear that that is as useful as it used to be. For server customers? Probably, though the bigger ones would also be more likely to trade an extra week or two lead time in exchange for a discount if they are buying hundreds or thousands of the things. For Joe User? Not so clear. If he is buying a Dell, as opposed to building his own or ordering from one of the numerous outfits who will build a 'DIY'-style PC for you, he would probably rather have a cheaper box with specs chosen for broad appeal, rather than a more expensive box with precisely tailored specs...

    For reasons of pure shipping speed(unless you fancy paying air-freight from the pacific rim...) overseas finishing cannot compete with the turnaround times of domestic finishing, which makes me wonder how much of this is driven more by a decline in demand for swift customization...

    I saw a couple of these 'early warning' systems in action during the Christchurch earthquakes. At best the alert came a few seconds before the quake - hardly early enough to save lives.

    Their value depends pretty sharply on where you are relative to the epicenter and what the threat is.

    Unfortunately, geologists are Not Ready Yet on actual earthquake prediction(they are, to be fair, pretty good at determining that a given fault is starting to look real damn unhappy; but pinning an event within a decade or a century, or even a year is pretty good on a geologic scale, not so useful for humans.
