  1. Re:More person, more cost. Fine. on Samoa Air Rolling Out "Pay As You Weigh" Fares · · Score: 5, Informative

    So I'm betting that 10 tones is far less than a 5% increase in overall weight. So the increase in costs divided among the passengers is going to get pretty small pretty quickly.

    It seems like they're being penny-wise/pound foolish on this...

    If Samoa Air were a normal international airline, you would be right. However, they are a regional airline with small prop planes, where individual passenger weight does make up a significant percentage of the total flying weight.

  3. Re:Security auditing is mostly about documentation on Ask Slashdot: Do-It-Yourself Security Auditing Tools? · · Score: 4, Insightful

    Hate to tell you, but security auditing is mostly about documentation. Checking that the right documents are in place and have been updated, verifying office procedures, physical security, etc. Technical tests are mostly about checking for the status and presence of files or configurations, not about probing networks or white hat hacking. There is a vaild business opportunity in pen testing, which is just one component of auditing, and is not even needed for every type of audit.

    This. While it would seem logical to put a round of known vulnerabilities into a scanner (like a Virus Scanner works) in the real world this is extremely tricky. Vulnerabilities that come about from combinations of different packages and different configurations interacting are very hard to systematically detect, and even if you do detect them they are just one piece in the huge puzzle that is information security.

    Case in point, I often get audit reports from "creditable" security professionals that there are a set of vulnerabilities in XYZ product, specific to "somesoft operating system 9.0", when in fact the product in question uses no such operating system (or even one similar to it) so the "audit" was obviously just a set of false-positives from a scanner tool. Scanner tools are just that, a TOOL, they are not even close to a true security solution that would produce a meaningful audit; that can only come (at least in this day and age) from a combination of tools and a *lot* of expertise.

    Do you really get 50 mbit sustained through 4G? My downloads always start fast, then quickly drop down to a much slower speed - I've always assumed that my carrier is throttling me on big downloads... i.e. small 1MB things like web pages load fast, sustained downloads are throttled. Do people really get fast 4G speeds for tens or hundreds of megabytes?

    I'm on Verizon and I have had a few sessions of 100MB+ downloads running at top speed all the way. Granted, I am not in a spot with a 10 Mbit+ signal very often but when I am, it is blazing. Of course take this with a grain of salt; Verizon is both creative and clandestine when it comes to service shaping, so they could very well use that tactic in certain congested areas.

  5. Re:That phone has 2GB of RAM on Ask Slashdot: Getting Apps To Use Phones' Full Power? · · Score: 1

    It's not difficult to have a phone draw more than the capacity of a USB port (the official spec limits power usage to 500mA/port).

    I remember when you put the Google/HTC G1 in wifi hotspot mode it would drain the battery, even when plugged in.

    Most phones ship now with a 1000mA charger, which is enough to just about top out the CPU (the HTC G1 days are LONG gone). I suggested a safeguard anyway, that is to make sure the phone is done charging before starting an app like that. If the phone has to go back into charging mode (if it is outstripping the current limit on the charger) then the (currently just hypothetical) app will pause again while the battery charges. Same goes for heat, current phones all have temperature sensors to monitor for battery runaway, that could be used to keep the temperature at a reasonable level.

    Your desktop idling, with the CPU governor set to 'conservative,' even with an IGP, would probably skate circles around an ARM device.

    My desktop idling will still consume more than 10W, and no it won't outperform my phone (my phone is a lot newer than my desktop, I suspect the same goes for a lot of people).

    While I agree:

    Government satellites are already, by-and-large, built by private contractors for overpriced contracts, by rent-seeking engineering firms. GOES sattellites, for example, weren't designed and manufactured by NOAA scientists, but BOEING or Space Systems/Loral or Lockheed Martin. The difference here would only be the job of running them.

    So, you propose we trade rent-seekers in the up-front purchase (who at least compete with each other), for rent-seekers in the long term operation (of which there is as of today, one)... Hmm...

    The only way privatizing makes sense to an economist is if there are multiple companies out there offering the same service. Trading a public entity (which can and do get audited on a regular basis) for a private one that is free to waste money at will, in the hopes that they will somehow find a way to do it cheaper, pretty much never works out. At best, they end up charging the same amount, but paying their workers/vendors less and issuing huge bonuses to the executives. Competition is key, and it's completely missing from this scenario. Get a few more bids, and it will get interesting.

    Also, my Nexus 7 certainly seems to download multiple files at once.

    This. Certain apps (like the play store) download one at a time because they are trying to be nice on your phone (since the time saved from multiple downloads is negligible anyway, unless you have a really good 4G signal). How much time do you spend waiting on play store app downloads anyway? The OS at large has no such restriction, you can download things from the play store while you are downloading things from a web page, or things from a Torrent, or whatever; it is all up to the app. I have run a Torrent client with 32 connections across 5 file downloads and Android had no problem with it (it did make video playback skip occasionally). I agree that phones are generally more powerful than the software expects at this point, but the way the question was worded, this is a problem looking for a solution.

    How about this: How can I get my phone/tablet to do compute work (folding @home, whatever) when it's plugged in and fully charged (like, most of the night)?

    This is true, but not all phone hardware OR all versions of Android support USB OTG, in fact only handsets that are less than about 2 years old typically do. Check up on the phone and the compatible software before making any plans. Then, the question becomes is there a particular pre-built APP or even a stable API for working with the hardware I/O and to that I would suspect the answer is no (since the hardware itself is extremely scarce). Bluetooth serial is probably the only thing remotely close to this sort of application that already exists on Android, and that even has a pretty specific use case and would take some hacking to turn into universal I/O.

    Perhaps if Mastercard and Visa hadn't allowed PaypaI to usurp what they could very well have done themselves, long ago, they wouldn't be in this situation. I've always wanted the ability to painlessly send someone money, directly, and it's idiotic that paypaI (and other 3rd party wallet services) are the only way to do it. Completely redundant.

    The problem with those kinds of transactions is that they are inherently risky, since there is not a merchant on hand to blame in the event of a chargeback. Visa and Mastercard stayed the hell away from that nightmare, and it is telling that only a company as skeezy as PayPal has managed to make it profitable for so long.

    It used to be that Paypal and similar services weren't there to take away transactions from normal merchants (since only small "peer to peer" transactions, like you mention, went through them) but Paypal has grown to be a behemoth that has elbowed it's way into every online merchant's payment options, for some strange reason (what good is it unless you for some reason already have money stored at the bank of paypal?). Mastercard and Visa are naturally skeptical, because PayPal is basically taking mindshare that they could easily shift to their own credit service (if they wanted to start being regulated like a legitimate business, that is.) This is the writing on the wall that PayPal should either rethink their strategy, or accelerate it. Visa, in their own right, has started basically a competitive service (V.me) and is actively going at merchants to reclaim some ground.

Of course, one other likely scenario is that we find a way to make more efficient use of newly created bio-material and therefore use it all up at or near the same time as the sun goes cold, so it wont have a chance to become oil.

    The other thing is that "using" renewable energy is possible on the normal grid by purchasing renewable energy through the utility.

This is the same way "competitive" energy markets in the US work, the electricity enters the grid from a mix of where the customers want it.

    The thing is, a credit card company is really only trying to find and/or convince customers to borrow to the point where they have too much debt to fully repay at any point in the near or medium term, and then charge just enough interest to keep them paying instead of filing for some sort of debt relief or bankruptcy. To think that credit card companies are in the business of only giving credit to those most worthy/capable of repaying is to completely miss the nature of the global banking/debt industry. Quite the opposite, if you are in a position to easily repay credit card debt you aren't a sought after customer. The model for that is certainly different compared to one whose intention is to find candidates who will be relatively successful and capable of full repaying at some medium-term point (10 years) and yield a comfortably high return for the investors.
