  1. Re:Test the Attachments on Ask Slashdot: How Do You Automatically Sanitize PDF Email Attachments? · · Score: 1

    This is already reality. So called "red pills" allow malware to find out if its are running in an emulator or virtual machine.

    Here's a paper that describes automatically generating such red pills:

    "A fistful of red-pills: how to automatically generate procedures to detect cpu emulators" by R. Paleari, L. Martignoni, G. F. Roglia, and D. Bruschi
    https://www.usenix.org/legacy/event/woot09/tech/full_papers/paleari.pdf

    The authors found more than 23k red-pills to detect QEMU and/or BOCHS.

    Let's look at what page 131 of the GAO report says about Table 8 (http://www.gao.gov/new.items/d11696.pdf).

    First of all, these are loans, not bailouts.

    Second, for at least half of the amount (the PDFC loans), the number is highly inflated: "For example, an overnight PDCF loan of $10 billion that was renewed daily at the same level for 30 business days would result in an aggregate amount borrowed of $300 billion although the institution, in effect, borrowed only $10 billion over 30 days."

  3. Similar work in a December 2010 paper on Chapel Hill Computational Linguists Crack Skype Calls · · Score: 2

    A December 2010 paper, "Uncovering Spoken Phrases in Encrypted Voice over IP Conversations", takes a similar approach.

    The article was published in ACM Transactions on Information and System Security, PDF version.

    The paper details a gap in the security of VBR compressed encrypted VoIP streams. The authors had earlier found that it is possible to determine the language that is spoken on such a VoIP call, based on packet lengths. Now they have expanded their research and show that itâ(TM)s possible to detect entire spoken phrases during a VoIP call. On average, their method achieved recall of 50% and precision of 51% for a wide variety of phrases spoken by a diverse collection of speakers (some phrases are easier to detect than others; the recall various from 0% to 98%, depending on length of the phrase and the speaker). In other words: they can detect fairly well if a certain phrase is being used in a conversation, even though the VoIP conversation is encrypted.

  4. Re:Waiting for a capable PostgreSQL front-end on PostgreSQL 9.0 Released · · Score: 5, Informative

    You know that you can point your MS Access client to any supported back-end right? Just create an ODBC connection on your Windows machine to your PostgreSQL server and you can use Access with pretty much all the features that work for the Microsoft JetEngine (PostgreSQL has ODBC drivers here; http://www.postgresql.org/ftp/odbc/versions/)

    Earlier this year we converted a huge Access application from MSSQL to PostgreSQL and the technical conversion, using ODBC to PostgreSQL instead of connecting to MSSQL, was a piece of cake.

    JavaConfig. It allows easy and type-safe access to configuration properties, for Java based applications.

    My previous employer, Chess in Haarlem, the Netherlands, agreed to make it Open Source (under a BSD license) after me and a few other colleagues had been working on it for a while. Proves that it's a cool company ;)

  8. Smart hoax? on Microsoft to sue Mike Rowe for Copyrights · · Score: 1

    Isn't it a bit early to judge this thing? The Register didn't even hear Microsoft's response yet.

    From the Register's article:

    "Can Microsoft really be attempting to take a phonetic-sounding domain name? Well, Mike is reassuringly candid and although we have not seen Microsoft's letter and the company has yet to confirm or deny its threats are real, it seems to hang together. Unless Mike is a first-rate hoaxer, it would appear that Microsoft really has lost the plot and is trying to extend the already flawed domain dispute rules into hitherto unexplored territory". [emphasis mine]

    True; it sounds real enough but it could also be a smart hoax.

    It'd be nice if there was a Netbeans module that would read the struts-config.xml and present it in a form, like the TLD module.

    I think that exactly the point KDan was making: IDE support for the struts-config and validation.xml files.

    I don't know about Netbeans, but there are a couple of them for Eclipse (Alpha Struts Editor, Easy Struts). The latter one already supports Struts 1.1.

  11. Use tools and frameworks on Elegant PHP Architectures? · · Score: 1

    I'm a reasonably experienced Java developer (4 years). We're mostly creating J2EE applications at my work.

    Recently I had to work in PHP as well; a friend of mine wanted a small website. It was quite a change!

    I know Java has its drawbacks, but the tooling is becoming really good: Eclipse, code beautifiers, Javadoc, Junit, StrutsTestCases, Hibernate ... they all make developing a lot easier.

    Tooling for PHP is another matter. There are editors, there are Eclipse plugins, but nowhere near the level of Java (or, of course, Visual Studio for that matter). It seems like all the tools are just a bit less mature (perhaps with the exception of database-access layers, there are quite good ones available). A point where PHP beats Java is of course deployment: simply change the source file, reload the page, and your application is deployed. That takes a bit longer in Java ;)

    However, tooling isn't the most important thing for a good system: the design is what really matters. This is not made easier by the lack of decent OO functionality of PHP. My approach was to stick with the 'Struts-way' as much as possible.

    There's a reasonable Struts-replacement (Phrame), which works pretty neat with the template engine Smarty.

    The project worked well -- but I'm happy to be back at Java. Somehow programming in PHP felt a bit 'ugly'. Although the code is quite readable, and the application works nicely, I don't have the same proud feeling I (sometimes :)) have when writing Java code.

    Don't know if it's an option, but I saw quite decently priced Java hosting: http://www.4java.ca/ (no personal experience with them though).

    But I wouldn't be surprised if one of the factors for the attention BBC gives to this project is the fact that is has been on Slashdot.

    Obviously KDE and Gnome are not just tools, or frameworks. They are quite complicated programs that are still constantly evolving. However, they can use Gnu make, gnu c, all kind of open source scripting languages "from the shelf". Gnome or KDE are examples for (currently) there is still a lot of work for developers, possibly 'closed source' (ie: MS Windows)...

    My point is that there is no need to re-invent the wheel for well-understood programs . I didn't mean to say all open source software falls into this category.

  22. Re:An interesting perspective on Perens Discredits Mundie's Attack On GPL · · Score: 1

    I agree with you; I think Jerry Plouffe is not right. One of the things that I consider a big advantage of Open Source is the fact that there is less need to re-invent the wheel all the time.

    In many software-companies software is created just for the purpose of this company (think about frameworks, scripting, tools) where this is not necessary at all. It is only done because creating it yourself is cheaper than buying it. However, using open-source variants of these tools, frameworks etc money will be saved. I believe this saving is good: it allows the developer to focus on their main product.

    This way there will be a change in focus for developers: less on the tools, more on the business logic they're implemented for their customer. Productivity will rise (good for the employer), and the job will be more interesting too I believe. Jerry will not have to be afraid for his job but should embrace Open Source where possible and enjoy his work more, and be more efficient for the same money spent.

  23. Re:Self compiling and newbie Slashdot readers on Mono's MCS Compiles Itself On Linux · · Score: 1

    In Modern Compiler Design the advantages of compiling your compiler in the language (system) you are developing are summarized as this:

    first, basic sanity check because it shows you're compiler and language are at least able to do work together

    second, an extended sanity check because typically a compiler is a BIG program. This means not only small test-programs will be compilable, but also a real-world, large-scale application.

    They mention as a possible disadvantage that there might be a danger that the language will be a bit biased towards creating a compiler. However, in case of C# (where the language is already defined) this is not the case of course.

    Say I had two programs, one done in all C++ and one done in all Java Now, if these numbers are right, then the C++ program is up to TWICE as fast as the Java one... I think I know which one I'll be using.
    As it reads on the website:

    Important: As stated on page 33 of the report; when the report uses the phrase X is 30% slower than Y, then this means that X uses 30% more time than Y to perform the same computation. This is the same as saying that X is 1.3 times slower than Y. So if X is 50% slower than Y, this does not mean X is half the speed of Y.

    This means that a Java version would take 1.2 to 1.5 times as much time as a C++ one, NOT 2 times as much.
