  • Google I/O 2010 - Making smart & scalable Wave robots

    Google I/O 2010 - Making smart & scalable Wave robots Google I/O 2010 - Making smart & scalable Wave robots Wave 201 David Byttow, Marcel Prasetya A smart robot must be able to store persistent data. Wave robots can store data in wave structures, like wavelets, datadocs, and annotations, instead of traditional datastores. A scalable robot must perform operations with minimal bandwidth. Wave robots can optimize by selecting the appropriate amount of context, the optimal events, and narrow filters for events. In this talk, we'll share best practices on data storage and scaling.

  • Getting Windows Azure SDK 1.1 To Talk To A Local DB

    - by Richard Jones
    Just found this, if you’re using Azure 1.1,  which you probably will be if yo'u’ve moved to Visual Studio 2010. To change the default database to something other than sqlexpress for Development Storage do this - Look at this - http://msdn.microsoft.com/en-us/library/dd203058.aspx At the bottom it states -   Using Development Storage with SQL Server Express 2008 By default the local Windows Group BUILTIN\Administrator is not included in the SQL Server sysadmin server role on new SQL Server Express 2008 installations.  Add yourself to the sysadmin role in order to use the Development Storage Services on SQL Server Express 2008.  See SQL Server 2008 Security Changes for more information. Changing the SQL Server instance used by Development Storage By default, the Development Storage will use the SQL Express instance.  This can be changed by calling “DSInit.exe /sqlinstance:<SQL Server instance>” from the Windows Azure SDK command prompt.

  • National ID Cards

    Have you heard about the national ID card? While I had heard little about this program I had not given it any real attention until recently while listening to Bill O’Reilly and Lou Dobbs. Both made some great points as to how such a card could increase security and reduce fraud in the United States [...] Related posts:Your Life And The Government Choices Cloud Computing In Corporate and Home Environments ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Method chaining vs encapsulation

    - by Oak
    There is the classic OOP problem of method chaining vs "single-access-point" methods: main.getA().getB().getC().transmogrify(x, y) vs main.getA().transmogrifyMyC(x, y) The first seems to have the advantage that each class is only responsible for a smaller set of operations, and makes everything a lot more modular - adding a method to C doesn't require any effort in A, B or C to expose it. The downside, of course, is weaker encapsulation, which the second code solves. Now A has control of every method that passes through it, and can delegate it to its fields if it wants to. I realize there's no single solution and it of course depends on context, but I would really like to hear some input about other important differences between the two styles, and under what circumstances should I prefer either of them - because right now, when I try to design some code, I feel like I'm just not using the arguments to decide one way or the other.

  • Why Enabling “Do Not Track” Doesn’t Stop You From Being Tracked

    - by Chris Hoffman
    The “Do Not Track” option is enabled by default in Windows 8’s Internet Explorer 10 and available in Firefox, Safari, and Opera. Google is even adding it to Chrome. There’s just one problem: it doesn’t actually prevent tracking. The Do Not Track check box can provide a false sense of security. While a few websites will pay attention to it, the vast majority of websites will ignore your preference.

  • How should I practice web server administration?

    - by Astyanax
    Security students can practice their skills with software like OWASP's webgoat or something similar to "hackthissite". Students interested in Operating Systems can study MINIX and PintOS, write shell scripts or study POSIX system calls. What would be the best course of action in order to practice Server Administration? Is there any such software/resource available, teaching you such skills with small lessons, or it is totally up to you? I've practiced live FreeBSD server administration and management of VMs (CentOS, Gentoo, Debian) under VirtualBox, but I always feel that this isn't enough and I must push myself harder. So, what would you recommend? What has worked for you?

  • Upgrading your Internet connection to obselescence

    - by TATWORTH
    Originally posted on: http://geekswithblogs.net/TATWORTH/archive/2013/10/11/upgrading-your-internet-connection-to-obselescence.aspxRecently I was approached by two UK Internet Service Providers to upgrade to a fibre connection. In each case I asked two questions:Can you provide me with a fixed IP Address?Is the equipment to be provided compatible with IPv6?None of the question was satisfactorily answered. One of the persons answering even suggested that granting a fixed IP Address would be a breach of security!I find it very disturbing that two companies that present themselves as innovative should still not be preparing for IPv6. The answer I would have expected was that all new equipment being supplied was IPv6 compatible and that plans were in hand for a switchover to IPv6. Instead new equipment would be supplied that would have to be replaced when IPv6 comes. Equally disturbing was that the call center people who answered did not know why a fixed IP address was important or why the change to IPv6 would have to come.I would rather not name and shame the two companies, however I will be looking elsewhere for my next Internet Service Provider.

  • Lubuntu 12.04 is a non-LTS release - does this mean that LXDE isn't, either?

    - by MHC
    Lubuntu 12.04 is not a long-term-support release. That's mostly due to a lack of manpower. But I don't use Lubuntu on my machine, I use LXDE over stock Ubuntu 12.04 LTS. So my question is: In the next five years, will there be security updates and bug fixes for LXDE-packages such as Openbox, PCmanFM and LXsession? Or does the "LTS" in 12.04 LTS only include stock Unity packages? I guess this question is just as relevant for any other DE out there.

  • My ubuntuone is broken, what is the problem?

    - by user6962
    I am on 10.10 and u1sdtool seems to be completely broken. I reinstalled it, no change. I can add my PC to the account, but it is added twice(!) every time I tried. So I have my netbook and two times my PC in the account. The netbook with 10.04 has no problems. Below is the error msg I get when attempting to startup Ubuntu One on the command line. desktop:~$ u1sdtool --status Oops, an error ocurred: Traceback (most recent call last): Failure: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. desktop:~$ Starting it from the Me Menu has the same effect, the HDD will get really busy for a minute and then nothing happens, the client will not start. Nothing in the syslog or anywhere.

  • What skills does a web developer need to have/learn?

    - by Victor
    I've been I've asked around, and here's what I gathered so far in no particular order: Knowledge Web server management (IIS, Apache, etc.) Shell scripting Security (E.g. ethical hacking knowledge?) Regular Expression HTML and CSS HTTP Web programming language (PHP, Ruby, etc.) SQL (command based, not GUI, since most server environment uses terminal only) Javascript and library (jQuery) Versioning (SVN, Git) Unit and functional test Tools Build tools (Ant, NAnt, Maven) Debugging tools (Firebug, Fiddler) Mastering the above makes you a good web developer.

  • How to use OpenGL functions from multiples thread?

    - by Robert
    I'm writing a small game using OpenGL. I'm implementing basic networking in this game and I'm facing a problem. I have a thread in my client socket class that check for available data, when there are data I raise an event like this : immutable int len = this.m_socket.receive(data); if(len > 0) { this.m_onDataEvent(data); } Then on my game class, I have a function that handle and parse data like this : switch(msgId) { case ProtocolID.CharacterData: // Load terrain with opengl, character model.... Im not able to call opengl functions because my opengl context is created from a different thread. But I really don't know how I can solve this problem, I tried Google but it's really hard to find a solution. I'm using D programming language if it can help.

  • Truly useful UML diagrams

    - by eversor
    UML has a jungle of Diagrams. Profile Diagrams, Class Diagrams, Package Diagrams... However, (IMH-and-not-too-experienced-O) I quite see that doing each and every diagram is overkill. Therefore, which UML Diagrams are more suitable in a web context, more expecificly a blog (we want to build it from scratchs). I understand that just because I used UML Diagrams does not imply that our code would be great and brilliant... but, it certainly would be better than just unplanified code...

  • dovecot main process terminated with status 89

    - by G. He
    I'm trying to configure dovecot/imap to run without SSL. I set ssl = no in 10-ssl.conf in /etc/dovecot/conf.d. However, with this setting, dovecot dies right away when it is started. I checked the log file and found the following: dovecot main process (4895) terminated with status 89 What does it mean? Is there a way for dovecot to run without ssl? The reason I do NOT want ssl is that my outlook complains the certificate cannot be verified. It is really annoying. And I only run the server on a very small lan and don't need that extra security.

  • What should I worry about when changing OpenGL origin to upper left of screen?

    - by derivative
    For self education, I'm writing a 2D platformer engine in C++ using SDL / OpenGL. I initially began with pure SDL using the tutorials on sdltutorials.com and lazyfoo.net, but I'm now rendering in an OpenGL context (specifically immediate mode but I'm learning about VAOs/VBOs) and using SDL for interface, audio, etc. SDL uses a coordinate system with the origin in the upper left of the screen and the positive y-axis pointing down. It's easy to set up my orthographic projection in OpenGL to mirror this. I know that texture coordinates are a right-hand system with values from 0 to 1 -- flipping the texture vertically before rendering (well, flip the file before loading) yields textures that render correctly... which is fine if I'm drawing the entire texture, but ultimately I'll be using tilesets and can imagine problems. What should I be concerned about in terms of rendering when I do this? If anybody has any advice or they've done this themselves and can point out future pitfalls, that would be great, but really any thoughts would be appreciated.

  • Make Apache encode or replace quotes instead of escaping them?

    - by mplungjan
    In the dcoumentation I read Format Notes For security reasons, starting with version 2.0.46, non-printable and other special characters in %r, %i and %o are escaped using \xhh sequences, where hh stands for the hexadecimal representation of the raw byte. Exceptions from this rule are " and \, which are escaped by prepending a backslash, and all whitespace characters, which are written in their C-style notation (\n, \t, etc). In versions prior to 2.0.46, no escaping was performed on these strings so you had to be quite careful when dealing with raw log files. This is a problem for Analog which is still the handiest analyser I use. I get .... "GET /somerequest?q=\"quoted string\"&someparm=bla" in the logfile and it is of course flagged as corrupt since Analog expects .... "GET /somerequest?q=%22quoted string%22&someparm=bla" or similar. I realise I can pre-process using something like perl -p -i.bak -e 's/\\"/%22/g' logfile But I'd rather not have to add this step to these files which are 50-90MB zipped per day Thanks for any pointers

  • Moving My Blog

    - by Hirt
    Oracle has, unfortunately, moved to a new blogging platform. For security reasons, it is no longer possible to use external tools, such as Windows Live Writer. Since this makes it too time consuming for me to blog, I've decided to only use my private blog, even for work related blog entries. This is where you can find my blog entries, from now on:http://hirt.se/blog/ Note that it is hosted on the poor server in my garage, hooked up to an ADSL-modem. It will probably be dog slow.

  • An alternative way to request read reciepts

    - by lavanyadeepak
    An alternative way to request read reciepts Sometime or other we use messaging namespaces like System.Net.Mail or System.Web.Mail to send emails from our applications. When we would need to include headers to request delivery or return reciepts (often called as Message Disposition Notifications) we lock ourselves to the limitation that not all email servers/email clients can satisfy this. We can enhance this border a little now, thanks to a new innovation I discovered from Gawab. It embeds a small invisible image of 1x1 dimension and the image source reads as recieptimg.php?id=2323425324. When this image is requested by the web browser or email client, the serverside handler does a smart mapping based on the ID to indicate that the message was read. We call them as 'Web Bugs'. But wait it is not a fool proof solution since spammers misuse this technique to confirm activeness of an email address and most of the email clients suppress inline images for security reasons. I just thought anyway would share this observation for the benefit of others.

  • How many tiers should my models have in a DB driven web app?

    - by Hanno Fietz
    In my experience, the "Model" in MVC is often not really a single layer. I would regularly have "backend" models and "frontend" models, where the backend ones would have properties that I want to hide from the UI code, and the frontend ones have derived or composite properties which are more meaningful in the context of the UI. Recently, I have started to introduce a third layer in between when database normalization created tables that did not really match the conceptual domain objects anymore. In those projects I have model classes that are equivalent with the DB structure, these become components of objects that represent the domain model, and finally these are filtered and amended for displaying information to the user. Are there patterns or guidelines for how, when and why to organize the data model across application layers?
