  • JPA generic field

    - by m.ugues
    Hallo all Is it possible to persist a generic field? I have this property on an Entity class ... private T payload; ... T extends EventMessagePayload and public interface StringPayload extends EventMessagePayload{ String getPayload(); } In my application i persist the field only when is of String type and during the save operation all works great. When I read the object instead JPA try to create a String object but instead is a StringPaylod. Is there a way to intercept the creation and handle the object marshalling? Kind regards Massimo

  • Find all records in database that are within a certain distance of a set of lat and long points

    I've seen all the examples and here's what I got so far. my table is simple: schools (table name) - School_ID - lat - long - county - extrainfo here's my code: <?php $con = mysql_connect("xxx","xxx","xxx"); if (!$con) { die('Could not connect: ' . mysql_error()); } else {} mysql_select_db("xxx", $con); $latitude = "36.265541"; $longitude = "-119.207153"; $distance = "1"; //miles $qry = "SELECT *, (3958.75 * ACOS(SIN(" . $latitude .

  • Reflections based on distance from plane

    - by Andrea Benedetti
    Let's consider, for example, a surface like the volleyball court, we can see that legs and shoes of the players are reflected, with a blur effect, but body and stadium don't (as each object not near to the court). I've already made a reflection effect, but it works as a specular reflection, and I need to achieve an effect like the photo above. So, I would like to make a reflection that is based on the distance between the object and the plane, in this manner a close object would reflect more than an object that is positioned far away from the plane. What is the best way to achieve this effect? My first idea was to use the depth value (taken from the reflected camera), and use that value to blend between reflection and court. But I don't know if it's a correct way. Edit: as rendering engine I use Ogre that already provides a reflections system: reflecting the camera through a plane (obviously I can select the models to draw from the reflected camera). After a render to texture pass I can blend the reflected texture with the original plane. So, if possible, I'm looking for a way that best suits my system.

  • WouldISurviveANuke Assesses Your Distance From Nuclear War Strike Sites

    - by Jason Fitzpatrick
    WouldISurviveANuke is a morbid Google Maps mashup that plots out the effective radius of nuclear weapons on major metropolitan areas, your distance from them, and your chances of survival. Visit the site, plug in your zipcode, and set the parameters (how big of a nuclear weapon and how large the nearest target city needs to be) to find out if you’re in the blast radius. We plugged in a downtown address in Detroit, MI. The verdict? Neither we nor the cockroaches will be coming out alive. If you plug in a location far enough away from the direct blast radius you’ll also get a quality of life report that spells out the effects of a local nuclear strike. As far as startling anti-nuclear proliferation arguments go, WouldISurviveANuke is an effective and interactive demonstration. Hit up the link below to try it out. WouldISurviveANuke [via Y!

  • Collabnet Subversion and Self Signed Certificates

    - by Robert May
    We installed Collabnet as our subversion server recently.  This is the first time that we’ve used it.  In general, it seems pretty good, but we ran into a problem with it.  People were getting the following error in Tortoise: OPTIONS of ’https://xxxx.xxxxxxxx.xxxx/svn/xxxxx’: SSL handshake failed: SSL error code – 1/1/336032856 (https://xxxx.xxxxxxxx.xxxx) The odd thing is that for some people, it worked, for others, it didn’t!  I also couldn’t find anything useful out on the internet. We had checked the Subversion Server should serve via https option in the settings, and all of the ports were open, etc. This option causes a self signed certificate to be used. What we discovered: Tortoise must use the same url as is in the Hostname field on the General settings for collabnet or you’ll get this error.  Basically, some people were using https://svn.xxxxxxx.xxxxx and others were using https://computername.xxxxxxxx.xxxx.  Because the host name said used the computer name version, the whole thing broke.  By changing the host name to the svn version, which is what they should be using, the problem went away.  The users do get the “Accept Certificate” prompt, but we can live with that!

  • Calc direction vector based on destination vector and distance from enemy in AS3

    - by Phil
    I'm working on a zombie game in AS3 where I want a character to be able to move away from a zombie depending upon how close the zombie is. The character also has a destination that it's trying to get too on the screen. Ok so I have 2 vectors, one pointing to my destination, and one pointing to the zombie which I then invert to get my "away" vector. I then turn the distance between my character and the zombie into a value between 0 and 1. And then I'm stuck on how to get a resultant vector for my character. How would I use my 0-1 value to calculate how much of the away vector is used and how much of the original destination vector is still left if that makes sense? to end up with 1 direction vector to move my character? So if the zombie is right where my character is, then my direction vector = away vector, and if I'm far away from the zombie than my direction vector = destination vector, but how do I calculate the in-between? Ideally need the answer in AS3.

  • Is it possible to force the WCF test client to accept a self-signed certificate?

    - by Lawrence Johnston
    I have a WCF web service running in IIS 7 using a self-signed certificate (it's a proof of concept to make sure this is the route I want to go). It's required to use SSL. Is it possible to use the WCF Test Client to debug this service without needing a non-self-signed certificate? When I try I get this error: Error: Cannot obtain Metadata from https:///Service1.svc If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.

  • How to detect hidden field tampering?

    - by Myron
    On a form of my web app, I've got a hidden field that I need to protect from tampering for security reasons. I'm trying to come up with a solution whereby I can detect if the value of the hidden field has been changed, and react appropriately (i.e. with a generic "Something went wrong, please try again" error message). The solution should be secure enough that brute force attacks are infeasible. I've got a basic solution that I think will work, but I'm not security expert and I may be totally missing something here. My idea is to render two hidden inputs: one named "important_value", containing the value I need to protect, and one named "important_value_hash" containing the SHA hash of the important value concatenated with a constant long random string (i.e. the same string will be used every time). When the form is submitted, the server will re-compute the SHA hash, and compare against the submitted value of important_value_hash. If they are not the same, the important_value has been tampered with. I could also concatenate additional values with the SHA's input string (maybe the user's IP address?), but I don't know if that really gains me anything. Will this be secure? Anyone have any insight into how it might be broken, and what could/should be done to improve it? Thanks!

  • Microsoft signed driver appears as publisher not verfied

    - by Priyanka Gupta
    Task at hand: Microsoft sign drivers on Win 7. I microsoft signed my driver package 3 times every time thinking I might have missed a step or something. However, I cannot seem to get rid of the Windows Security error message "Windows can't verify the publisher of this driver software'. This is not the first time I have signed the driver packages. I was successfully able to sign other driver packages a few months ago. However, with this driver package I keep getting Windows security dialog box. Here's the procedure I follow - Create a new cat file using INF2CAT tool. Self sign the driver using a Versign Class 3 Public Primary Certification Authority - G5.cer. Run the microsoft tests on DTM Servers and clients with the devices that use this driver. Create WLK submission package. Self sign the cab file. Submit the package for certification. The catalog file that comes back after successfully passing tests says Name of signer "Microsoft Windows Hardware Comptibility Publisher". When I check the validity of signature using SignTool, it says the signature is vaild. However, when I try to install the driver with new signed catalog file the windows complain. Any ideas? Edit 11/12/2012: Reply to Eugene's comment Thanks for the help, Eugene. Yes. I did sign two other driver packages before. One of them was modified version of WinUSB driver. I am using the same certificate I used when I signed those two driver packages a few months ago. It costs $250 per signing from Microsoft. I would think that Microsoft would complain about it during certification if the certificate is wrong. I use the following command to self sign the CAT file.

  • What is the maximum distance from an anchor point to a bezier curve?

    - by drawnonward
    Given a cubic bezier curve P0,P1,P2,P3 with the following properties: • Both P1 and P2 are on the same side of the line formed by P0 and P3. • P2 can be projected onto the line segment formed by P0 and P3 but P1 cannot. What is the T value for the point on the curve farthest from P3? Here is an image with an example curve. The curve bulges on the left, so there is a point on the curve farther from P3 than P0. I found this reference for finding the minimum distance from an arbitrary point to a curve. Is trial and error the only way to solve for maximum distance as well? Does it make any difference that the point is an anchor on the curve? Thanks

  • Implementation of a distance matrix of a binary tree that is given in the adjacency-list representation

    - by Denise Giubilei
    Given this problem I need an O(n²) implementation of this algorithm: "Let v be an arbitrary leaf in a binary tree T, and w be the only vertex connected to v. If we remove v, we are left with a smaller tree T'. The distance between v and any vertex u in T' is 1 plus the distance between w and u." This is a problem and solution of a Manber's exercise (Exercise 5.12 from U. Manber, Algorithms: A Creative Approach, Addison-Wesley (1989).). The thing is that I can't deal properly with the adjacency-list representation so that the implementation of this algorithm results in a real O(n²) complexity. Any ideas of how the implementation should be? Thanks.

  • Given the lat/lon of 2 close points on earth (<10m), How do I calculate the distance in metres?

    - by Rory
    I have the lat/lon of 2 points on the earth. They are really close together, <10m. Let's assume the earth is flat. How do I calculate the distance between them in metres? I know about tools (PostGIS, etc.) that can do this correctly, however I'm just doing a rough and ready type, and I'm OK with low accuracy. At such small sizes a difference of 1% is only 10cm, which is fine for me. I'm doing this in stock python. I'm OK with a standard Euclidean distance thing.
