  • America The Vulnerable

    - by Naresh Persaud
    At the Executive Edge this week, Joel Brenner shared his perspective on the state of cyber-security. Today our most critical military and corporate secrets are under attack. In his presentation, Joel shared his perspective on how organizations can can better prepare for the changing security climate. The amount of state sponsored espionage has highlighted weaknesses in our national security infrastructure. The Internet was primarily intended to provide a means of collaboration for non-commercial entities. Today it is the backbone of our digital commerce and digital experience and it was not designed to secure the activities and data we share today.  Check out "America The Vulnerable" and learn more.

  • How to write a network game? [closed]

    - by Tom Wijsman
    Based on Why is so hard to develop a MMO?: Networked game development is not trivial; there are large obstacles to overcome in not only latency, but cheat prevention, state management and load balancing. If you're not experienced with writing a networked game, this is going to be a difficult learning exercise. I know the theory about sockets, servers, clients, protocols, connections and such things. Now I wonder how one can learn to write a network game: How to balance load problems? How to manage the game state? How to keep things synchronized? How to protect the communication and client from reverse engineering? How to work around latency problems? Which things should be computed local and which things on the server? ... Are there any good books, tutorials, sites, interesting articles or other questions regarding this? I'm looking for broad answers, but specific ones are fine too to learn the difference.

  • How to switch off wifi on startup or from the console

    - by mit
    I have installed ubuntu 10.04 on a laptop. Wifi is switched on by default on startup. I can disable it rightclicking the network manager icon in the gnome bar. How can I set it to have wifi switched off as default? Alternatively, how can I switch off wifi on the console? I tried already the rfkill command but it does not list any devices and it does not switch off wifi, I tried different parameters. This is a standard install of the Ubuntu 10.04 i386 Desktop Live CD on an IBM T40 Laptop. EDIT A: This is the output of some rfkill commands on my system, and it does not affect the wifi of the laptop: $ rfkill --help Usage: rfkill [options] command Options: --version show version (0.4) Commands: help event list [IDENTIFIER] block IDENTIFIER unblock IDENTIFIER where IDENTIFIER is the index no. of an rfkill switch or one of: <idx> all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm $ rfkill list $ rfkill list wifi $ rfkill list all $ rfkill list wlan $ sudo rfkill list all $ sudo rfkill block all $ sudo rfkill block wlan $ sudo rfkill block wifi $ EDIT B: Now I found out that sudo ifconfig eth1 down turns it off. And I can turn it on through the gnome network applet again. But the applet does not reflect the change from the commandline, it stills believes wifi is switched on. I have to switch it off and on again on the applet to switch it on again, when I switched it off from the console. Is there a better way? This is what the syslog looks like when I switch wireless off and on again from the network manager: NetworkManager: <info> (eth1): device state change: 3 -> 2 (reason 0) NetworkManager: <info> (eth1): deactivating device (reason: 0).

  • HP 510 laptop doesn't suspend when I close the lid

    - by Yuri
    I have an HP 510 laptop with Ubuntu 12.04. I have all the correct settings for suspending when the lid is closed, as far as I can tell, so I think it's a problem with detecting the event. The way it "should" be detected, from what I can see, is a little hardware switch that is pushed when the lid closes. This switch manually puts off the backlight, and sends the suspend signal. All I can think is that the signal isn't being properly interpreted. Can anyone suggest a fix? Update: I tested whether the button was actually working based on the suggestion by josinalvo, and I found that in the directory /proc/acpi/button/lid/ there is no LID directory. There is, however, a C1CF folder, and in it is a state file. When using the this file instead of ID, I discovered that, no, when I close the lid, the state does not change.

  • ScreenManagement how do I had different controls?

    - by DiasFrancisco
    I saw a question here using DataTemplates with WPF for ScreenManagement, I was curious and I gave it a try I think the ideia is amazing and very clean. Though I'm new to WPF and I read a lot of times that almost everything should be made in XAML and very little should be "coded behind". My questions resolves about using the datatemplate ideia, WHERE should the code that calls the transitions be? where should I define which commands are avaiable in which screens. For example: [ScreenA] Commands: Pressing B - Goes to state B Pressing ESC - Exits [ScreenB] Commands: Pressing A - Goes to state A Pressing SPACE - Exits where do I define the keyEventHandlers? and where do I call the next screen? I'm doing this as an hobby for learning and "if you are learning, better learn it right" :) Thank you for your time.

  • Implementing a FSM with ActionScript 2 without using classes?

    - by Up2u
    I have seen several references of A.I. and FSM, but sadly I still can't understand the point of an FSM in AS2.0. Is it a must to create a class for each state? I have a game-project which also it has an A.I., the A.I. has 3 states: distanceCheck, ChaseTarget, and Hit the target. It's an FPS game and played via mouse. I have created the A.I. successfully, but I want to convert it to FSM method... My first state is CheckDistanceState() and in that function I look for the nearest target and trigger the function ChaseState(), there I insert the Hit() function to destroy the enemy, The 3 functions that I created are being called in AI_cursor.onEnterframe. Is there any chance to implement an FSM without the need to create a class? From what I've read before, you have to create a class. I prefer to write the code on frames in flash and I still don't understand how to have external classes.

  • MAAS fails to Commission nodes

    - by user3644848
    I'm evaluating MaaS/Juju. I followed instructions in this link http://maas.ubuntu.com/docs1.5/install.html to setup MaaS. I'm running this in Oracle VirtualBox environment so Power options are not configured for the VMs. PXE booting VM works fine. The node shuts down itself and registers with MaaS in Declared state. Issues: a) When I Commission the VM (which is in the Declared state), first it gets IP-Config: no response after 60 secs - giving up errors. (See link below for a screenshot). b) Fails to mount the boot device and drops into initramfs prompt. I've copied logs here: https://www.dropbox.com/sh/5gy9nnonbnccufo/AAD9o4awSOtyaCCmRe5q7rBva Any help to get past this is greatly appreciated. Thanks!

  • What norms/API for monitoring my servers?

    - by dystroy
    I have a dozen server applications installed on my customers intranets (they can send http requests over the internet but cannot be called from outside). They're written in various technologies, mainly java and Go. I want them to regularly push information about their state towards a central server which is visible on internet. Some of this information is generic (is it ON ?), some is specific (size of a cache in an application for example). The main goal is to be able to make a small web page on which I could instantly check the state of every servers. And maybe later add some kind of notification in case of problem. Obviously I can do this by writing a few dozen lines of code each side (or a little more if I put this data in a database) but in order to ease future evolution, it could be interesting to use some existing norms or libraries. So, what are the current opensource free and light solutions to do this, preferably with no central configuration when I add a server ? I'd prefer a norm over a library.

  • How to properly do weapon cool-down reload timer in multi-player laggy environment?

    - by John Murdoch
    I want to handle weapon cool-down timers in a fair and predictable way on both client on server. Situation: Multiple clients connected to server, which is doing hit detection / physics Clients have different latency for their connections to server ranging from 50ms to 500ms. They want to shoot weapons with fairly long reload/cool-down times (assume exactly 10 seconds) It is important that they get to shoot these weapons close to the cool-down time, as if some clients manage to shoot sooner than others (either because they are "early" or the others are "late") they gain a significant advantage. I need to show time remaining for reload on player's screen Clients can have clocks which are flat-out wrong (bad timezones, etc.) What I'm currently doing to deal with latency: Client collects server side state in a history, tagged with server timestamps Client assesses his time difference with server time: behindServerTimeNs = (behindServerTimeNs + (System.nanoTime() - receivedState.getServerTimeNs())) / 2 Client renders all state received from server 200 ms behind from his current time, adjusted by what he believes his time difference with server time is (whether due to wrong clocks, or lag). If he has server states on both sides of that calculated time, he (mostly LERP) interpolates between them, if not then he (LERP) extrapolates. No other client-side prediction of movement, e.g., to make his vehicle seem more responsive is done so far, but maybe will be added later So how do I properly add weapon reload timers? My first idea would be for the server to send each player the time when his reload will be done with each world state update, the client then adjusts it for the clock difference and thus can estimate when the reload will be finished in client-time (perhaps considering also for latency that the shoot message from client to server will take as well?), and if the user mashes the "shoot" button after (or perhaps even slightly before?) that time, send the shoot event. The server would get the shoot event and consider the time shot was made as the server time when it was received. It would then discard it if it is nowhere near reload time, execute it immediately if it is past reload time, and hold it for a few physics cycles until reload is done in case if it was received a bit early. It does all seem a bit convoluted, and I'm wondering whether it will work (e.g., whether it won't be the case that players with lower ping get better reload rates), and whether there are more elegant solutions to this problem.

  • Using The Windows Server AppFabric Cache with ASP.NET

    Did you know that you can use the AppFabric Cache with ASP.NET?  AppFabric Cache provides an ASP.NET session state provider.  There are a number of reasons that you would want to consider using the AppFabric Cache instead of other caching technologies, including the built in ASP.NET caching. The AppFabric Cache provides a number of benefits to ASP.NET programmers.  When web applications need to maintain state, especially across a Web Farm, or needs to maintain objects across restarts...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • "static" as a semantic clue about statelessness?

    - by leoger
    this might be a little philosophical but I hope someone can help me find a good way to think about this. I've recently undertaken a refactoring of a medium sized project in Java to go back and add unit tests. When I realized what a pain it was to mock singletons and statics, I finally "got" what I've been reading about them all this time. (I'm one of those people that needs to learn from experience. Oh well.) So, now that I'm using Spring to create the objects and wire them around, I'm getting rid of static keywords left and right. (If I could potentially want to mock it, it's not really static in the same sense that Math.abs() is, right?) The thing is, I had gotten into the habit of using static to denote that a method didn't rely on any object state. For example: //Before import com.thirdparty.ThirdPartyLibrary.Thingy; public class ThirdPartyLibraryWrapper { public static Thingy newThingy(InputType input) { new Thingy.Builder().withInput(input).alwaysFrobnicate().build(); } } //called as... ThirdPartyLibraryWrapper.newThingy(input); //After public class ThirdPartyFactory { public Thingy newThingy(InputType input) { new Thingy.Builder().withInput(input).alwaysFrobnicate().build(); } } //called as... thirdPartyFactoryInstance.newThingy(input); So, here's where it gets touchy-feely. I liked the old way because the capital letter told me that, just like Math.sin(x), ThirdPartyLibraryWrapper.newThingy(x) did the same thing the same way every time. There's no object state to change how the object does what I'm asking it to do. Here are some possible answers I'm considering. Nobody else feels this way so there's something wrong with me. Maybe I just haven't really internalized the OO way of doing things! Maybe I'm writing in Java but thinking in FORTRAN or somesuch. (Which would be impressive since I've never written FORTRAN.) Maybe I'm using staticness as a sort of proxy for immutability for the purposes of reasoning about code. That being said, what clues should I have in my code for someone coming along to maintain it to know what's stateful and what's not? Perhaps this should just come for free if I choose good object metaphors? e.g. thingyWrapper doesn't sound like it has state indepdent of the wrapped Thingy which may itself be mutable. Similarly, a thingyFactory sounds like it should be immutable but could have different strategies that are chosen among at creation. I hope I've been clear and thanks in advance for your advice!

  • Template standard controls for an entirely new look and feel

    - by T
    This is the  Ineta Live player without the O’Data Feed.  It is a good example of taking the plain Media Player provided with the Encoder install and re-templating it to make it your own.  It also has a custom scrub control that is added in.  I generally put my tempates in a separate resource file.  On this project, I discovered that I had to include the template at the document level because I needed the ability to attach some code behind to fire change state behaviors.  I could not use the blend xaml behaviors for change state inside the template because the template can’ determine the TargetObject.   Version 1.01 – 6/10/09 (wow how did a week slip by)

  • How can I make a 32 bit render target with a 16 bit alpha channel in DirectX?

    - by J Junker
    I want to create a render target that is 32-bit, with 16 bits each for alpha and luminance. The closest surface formats I can find in the DirectX SDK are: D3DFMT_A8L8 // 16-bit using 8 bits each for alpha and luminance. D3DFMT_G16R16F // 32-bit float format using 16 bits for the red channel and 16 bits for the green channel. But I don't think either of these will work, since D3DFMT_A8L8 doesn't have the precision and D3DFMT_G16R16F doesn't have an alpha channel (I need a separate blend state for alpha). How can I create a render target that allows a separate blend state for luminance and alpha, with 16 bit precision on each channel, that doesn't exceed 32 bits per pixel?

    I am starting my Computer science degree at a local community college in Programming using C++. However, i will be transferring to a 4-year university. Does anyone have any insight on university programs? I know Cal State Fullerton has a degree with a minor in Game Dev. however, is that as important as getting a degree from a really great school? if i could shoot for something like Cal Poly would that be better? Or even Stanford or SF state being so close to so many gaming companies up there in the bay area? thank you in advance for any guidance.

SolutionWe can achieve the same by giving following EL to inlineStyle property of every column inside af:table: #{row.row.entities[0].entityState == 0?'background-color:#307D7E;':''}ExplanationHere is the explanation for row.row.entities[0].entityState given inside EL which returns the state of the row(i.e, New, Modified, Unmodified, Initialized etc.)row - Refers to a tree node binding(instance of FacesCtrlHierNodeBinding) at runtimerow.row - Refers to an instance of row that the tree node is based onrow.row.entities[0] - Gets the Entity row at zeroth index. In most of the cases, the table will be based on single entity. If your table is based on multiple entities then the index needs to be given accordingly.row.row.entities[0].entityState - Gets Entity Object's current Entity-state in the transaction.(0 - New, Modified - 2, Unmodified - 1, Initialized - -1,  etc.,)
