>(Remember, if the kindly gentlemen of the constabulary ask you why you like privacy, > the canonical rejoinder before referring them to your attorney, > is to ask if any of their windows at home have drapes, and why.) Since we live in a time of great controversy regarding the trade-off between privacy and national security; it seems to me the question should be: " Justify to me, precisely why you need to know ' this', in terms of your legislated task ? "; .rather than me needing to justify why I want privacy !. regards Rohan McLeod

Memory check
by Daniel Jitnah 02 Aug '13

02 Aug '13

Hi all, I have a laptop that is failing to boot - starts boot but then stops.(any boot media: HD, CD or USB, same result) It reports 1007Mb on bios memory check, which seems like a strange number to me??? (it also has 16Mb reserved - so it seems to have lost 1Mb??- it has 1Gb installed) - is this likely a memory stick problem? Cheers Daniel

There is both a (feature limited) free version and a fully featured paid version, though I'm not sure what the feature differences are[2]. OsmAND supports downloading of map and voice data so you do not need a 3/4g data connection whilst on the go. Hopefully this will satisfy your requirements of not having a data plan or lots of 3g data. I've used OsmAnd for it's mapping capabilities for quite a while and really like it. I've, not however, really used the navigation function as it has been added relatively recently & I got used to Google Navigate so I can't comment on how good this feature is. Either way, it might be worth considering. [1] http://osmand.net/ [2] http://osmand.net/en/installation-menu.html

IEEE SSIT talk: Thu 1 Aug 18:30 Uni. Melb.: Water Quality Management: The Case for Real Time ...
by Rodney Brown 30 Jul '13

30 Jul '13

SSIT Australia Chair Adj Prof Philip Hall will talk on; *Water Quality Management: The Case for Real Time Monitoring &Reporting.* The talk will occur on Thursday the 1st of August 2013 from 6.30 to 7.30pm at the University of Melbourne, Parkville Campus, Alan Gilbert Lecture Theatre 103. /Further details on speaker and abstract below./ *Location:* University of Melbourne, Parkville Campus, Alan Gilbert Lecture Theatre 103, Corner Grattan & Barry Streets *Organised by:* IEEE SSIT Chapter (and as part of preparation for an Oceanic Engineering Society chapter) *Abstract:* Despite significant advances in sensor and communication technologies, water quality monitoring (WQM) is still primarily undertaken through small-scale and single-application sampling and testing that is limited by the available techniques and only provides selective data for decision support tools. The effects of diffuse pollutants and their distribution within water bodies and transboundary river systems are, therefore, difficult to capture, as is determining the exact point and timing of their release into a defined "water system". Improved data capture and timely analysis, enabled by innovative sensor technologies and communication networks, is an important aspect of compliance monitoring. This is particularly important for international and trans-border agreements where changes in water distribution, quality, and availability associated with regional climate variability are already creating challenges for future water, energy and food security. Therefore, by removing the long lead times between when the sample was taken to completion of sample testing and data analysis, it is not only possible to develop and implement an effective WQM network and management framework that provides for real time data capture and analysis, but one that also provides for flexible policy settings, an early warning and situation management capability, and opportunities for greater compliance in water resource management. http://ymlp.com/zcW6Td

Basics of smartphone security
by Rick Moen 29 Jul '13

29 Jul '13

I found this bit about hazards uniquely faced by internation travelers very interesting: Q: Do you think organizations are understanding and taking the threat among these new mobile attack vectors seriously yet? Are security managers really getting it? Why or why not? A: The most-security-aware organizations are taking these threats very seriously. They're destroying phones after taking them to hostile areas with known malicious carriers, they're limiting what information gets copied to the default inbox/contact list on devices, they're limiting what applications can be installed on devices which have access to enterprise infrastructure. [...] Q: In your presentation, you specifically referred to some of the threats mobile users are facing now while traveling internationally. What are you observing? A: There are two major threat categories when it comes to international travel, the malicious foreign carrier and the enterprising private mobile attacker. These threats result from the fact that citizens of a foreign country generally have no rights to privacy and no official recourse if their information gets stolen while they are in the foreign country. I already spoke about how foreign carriers have total control over devices which are associated with their networks. Probably the most alarming thing we've seen happen in our tests is how foreign carriers can steal the cryptographic seed values from soft-tokens installed on smartphones. One take-away I'd love to get across to all of your readers is to never let soft-tokens become a solution to be relied on for organizations which have a large number of international travelers. [...] http://www.csoonline.com/article/print/733691 I'm wary of distortions, outright bullshit, and vague handwaving by security industry guys. As usual, interviewee Aaron Turner (of IntegriCell, formerly Idaho National Laboratory, formerly Microsoft security division) is vague about how code gets executed to do undesirable things. Smartphone 'soft-tokens' means virtual dongles used for (supposed) two-factor authentication such as Symantec VIP or SecurEnvoy SecurAccess. Pity Turner doesn't say _how_ iOS, Android, and BlackberryOS yield 'total control over devices' to local carriers. Turner goes on, in the bit about international travelers, to talk about a cruise ship passenger who uses a cafe's WiFi in port, and 'the coffee shop owner has realized he can make more money selling your address book to spearfishers than he ever can make selling you even his most-expensive latte'. I'm intrigued, Mr. Turner. How does connecting a smartphone to a WAP give the WAP owner automatic access to the smartphone's address book? I'm used to assuming that networks are dangerous and untrustworthy and layering things trustworthy over them. Why is that approach not feasible with a smartphone -- or is Turner just another guy selling unnecessary gear to the rubes?

Fw: Fibonacci day
by DanyJ 29 Jul '13

29 Jul '13

Begin forwarded message: Folks, something a little off topic. At 3:02:01 on the 5th of August this year it will be a very special date. The date will form the Fibonacci sequence, where each term is the sum of the two before it. In this case, it will be the 1st second of the 2nd minute of the 3rd hour of the 5th day of the 8th month of the 13th year of the 21st century. Such a sequence will not occur again, and needs to be celebrated properly. OK, its not Linux, but I thought it worth sharing.

Related to this: I am thinking of replacing an aging Nokia "dumbphone" with another one but have problems to figure out which one can be used as a WiFi hotspot. Do you know one? I am not reading/browsing on a phone but prefer to have a tablet connected when needed. Well, security-wise it separates network carrier and phone functionality from the "browsing/email computer" although it isn't my main concern. I don't have the habit of being online 24hrs, and find phone screens to small to be enjoyable (or too big to carry in my pocket) I like the idea of two screens folded but these devices don't seem to be very popular. They usually disappear from the market before I get around to think of them more seriously. Regards Peter

Strongly concur with recent comments, here, that the embedded market tends to be a completely different mentality, where the notion of anyone being selective about what one is willing to run is simply an alien concept. Back when I was working at Cadence Design Systems (a big EDA-industry company), I found myself being told by my new boss that he would like me to install various bits of proprietary software on my home laptop for company purposes. I very politely informed him that (1) my laptop ran Debian and not MS-Windows or Mac OS X, but also (2) for reasons of local privacy and security policy, only software I had approved and selected would be installed and run there. However, I said, if he wanted to issue me a company machine to run company-specified software, that would perhaps work. And I remember the look of intense surprise. The 'I installed [foo] because a Web site told me I needed to' population is, actually, almost everyone except us freaks. It's well to remember that, because it's easy to forget.

It felt > good. ;-) I'm delighted that people enjoy cool Internet-enabled applications like this, and under no circumstances would tell a devotee he/she shouldn't run them.[0] At the same time, I keep being bemused by the security and privacy implications of such things -- by which I don't mean the little morbid program so much as I do the Google Earth engine needed to run it. Google Earth in either its browser plugin or standalone form isn't just a proprietary opaque (by which I mean unauditable by anyone outside Google, Inc.) binary program but also such an offering _specifically_ from one of the most prying, nosy, large Internet corporations on Earth, a corporation whose entire business model is based on data-mining computer users to glean data valuable to them and to their customers. The Google Earth program[1] must be installed with root (for Unixes) or administrator (for Windows) privilege, hence will have total access to everything on your machine, and hooks directly into the video software layers (for 3D imaging) and sends real-time data (into which you have no visibility) from your computer back to Google. And you're being told you can do this as a non-customer of Google: Google's _actual_ customers (the people who pay them money for services) are entitled by law to an implied warranty of good faith and fair dealing. Users who elect to download their 'free' proprietary programs or use their 'free' Web services have no such entitlment, and are (as the saying goes) not customers but rather product. tl;dr: Google Earth is a huge 'trust me' from the most prominent data-mining enterprise in existence, one that for quite a few years has made quite clear that it will intrude on user privacy whenever and wherever it wants.[2] And _that_, Ben Avery, is one of the things one avoids by sticking to open source offerings from trustworthy (and cross-checked) sources, even if you don't get to see dancing hamsters, animated birthday cards, and nuclear explosions requiring one to download and run an 'app' from nowhere-in-particular (or worse, from someone you know whom you have _no_ reason to trust). _Or_ one can just not bother being careful, and good luck with that. [0] Not because you shouldn't, but just because I don't want to waste time arguing with people who enjoy the benefits of being careless about software and are effectively treating Internet and software security as Someone Else's Problem. [1] The standalone version, at least. The browser plugin version can presumably be installed with only user-level authorisation -- which is quite bad enough.

Unlocked android phones with LTE support
by Jason White 25 Jul '13

25 Jul '13

I was planning to buy one of these devices: https://play.google.com/store/devices/details/Samsung_Galaxy_S_4?id=samsung… but discovered that (1) they are available in the U.S. only, and (2) not surprisingly, they are designed for North American frequencies, i.e., 1700 MHz rather than the 1800 MHz bands used in Australia by the major carriers. The advantage, of course, is that the Google devices have unlocked boot loaders so you can replace the firmware yourself, if needed - and I might need it, for various reasons. So if one is looking for an LTE-capable phone with an unlocked boot loader that supports Australian frequency bands, am I right that there are no options on the market at the moment? I can afford to wait a little longer - the equivalent of the above device with the right frequencies supported would be ideal of course.
