(not to a user or page's wall) | I'm working on creating a Facebook application that re-creates a live stream and I'm having trouble with permissions. Originally the 'stream' was going to the application's wall, but a user cannot post onto an application's wall without liking the page first (and therefor granting publish permissions to that app's wall).
Our current solution is a Facebook social plug-in - http://developers.facebook.com/docs/reference/plugins/live-stream/- which works fine but we're not able to customize it. Does anyone know of a way using the Facebook API to post to a live stream object? Ideally I'd like to re-create the social stream by hand using a combination of the FQL to fetch new posts made in the stream and using their API to create new posts for the stream. Any leads would be fantastic. | javascript | facebook | api | null | null | null | open | Using the Facebook API to post to live stream plugin? (not to a user or page's wall)

I am an entry level system architect. We want to design a site for mobile phones (no javascript / ajax) with around **5000 concurrent users** *[ concurrent users and not daily active users ]*. As it is a mobile site, entire processing must be done on server side and plain HTML will be thrown to the client.
We have decided to use 64 bit Linux, Java 1.6 or above and Tomcat 7 for this. Hardware will be on Amazon cloud: 6-8 cores with 16GB RAM. We will be using just JSP and Servlets. Database is MYSQL. We may put 2-3 servers in parallel under load balanced if needed.
Please help me with the following doubts:
1. Please help me with the advanced configuration parameters of tomcat. What should be the number of threads, number of maximum connections for the above requirement on given hardware.
2. What should be the memory specifications of JVM ?
3. What is the maximum number of concurrent connections tomcat can handle in above setup ? Are there any other better alternatives for tomcat for such requirement ?
4. Will the Java's default gc be able to handle the garbage collection entirely ? Or we should look at some other additional alternatives ?
5. We will make our app stateless so that it can be extended easily by adding multiple servers horizontally if needed. Any additional best proven technologies for the same ?
6. I wish to avoid RMI etc. overheads hence decided to stay away from EJB and other complex J2EE technologies. Is that a better decision or not ?
7. Some people advised me to go for PHP instead of Java claiming PHP as a better for web projects. But considering available programming resources on our side, we decided to stick with J2EE only. Should I seriously consider that option ?
Optimizing at DB level will be a separate discussion thread, so please don't give inputs on that here. We have already shortlisted memcached or redis for caching.
I wish to ask this question as a discussion thread than just a spoon-fed answer.
Thanks in advance for your feedback.

Boost has recently become available on the project on which I'm working, and I don't have much experience with it. Boost has so many parts and features that it's hard to know where to get started in learning it - especially since I'll be trying to learn it while making production code.
So, I would greatly appreciate it if someone could list around 3 to 5 features which are very useful in general, every-day programming and state why they're useful. I'm not asking you which is best, or trying to get a debate - I just want to know some good features to start learning and using immediately. I don't need code samples either, I'll be more than happy to research how to use the features myself after I know which ones are sensible to start learning now.

I'll accept any answer with a concise list of features that are sensible :) | 4 |

Can I understnd the invoking sequence of this segment of code as follows.
At first, he run method at line 5 is called. Due to its particular parameter setting, 3 parameters, the compiler automatically uses the run method defined in line 13. ( if we only have one parameter in line 5, then compiler will use the run method defined in line 9 instead.
For the run method defined in line 9, it will call run method at line 10, which essentially is the run method defined at line 13.

I've read various opinions about whether Bcrypt or PBKDF2 is a better key derivation hashing method (see http://stackoverflow.com/questions/1561174/sha512-vs-blowfish-and-bcrypt
and http://stackoverflow.com/questions/4433216/password-encryption-pbkdf2-using-sha512-x-1000-vs-bcrypt).
The answer seems to depend on which expert you ask and on a lot of complicated factors that are not easy to analyze.

3. Pan by pressing left mouse button.

I have most trouble with 1, and haven't attempted 2. Panning is easy (there are lots of examples).

There is a time window (both records have a DateTime column), if one record is very close in time (within 5 seconds) to another then it is a potential match, the record which is the closest in time is considered a complete match. There are other fields which help narrow this down also.
I wrote a stored procedure which does this matching on the server before returning the
full, matched dataset to a C# application. My question is, would it be better to pull in the 1 million (x2) rows and deal with them in C#, or is sql server better suited to perform this matching? If Sql server is, then what is the fastest way of pairing data using datetime fields?
Right now I select all records from Table 1/Table 2 into temporary tables, iterate through each record in Table 1, look for a match in Table 2 and store the match (if one exists) in a temporary table, then I delete both records in their own temporary tables.
I had to rush this piece for a game I'm writing, so excuse the bad (very bad) procedure... It works, it's just horribly inefficient! The whole SP is available on pastebin: http://pastebin.com/qaieDsW7
I know the SP is written poorly, so saying "hey, dumbass... write it better" doesn't help! I'm looking for help in improving it, or help/advice on how I should do the whole thing differently!

where category_list is list that contain category objects. Area is jQuery <div> object.
In other browsers (except IE) i get area with all needed categories, but in IE i get only new received categories(that just create DomObject), other old objects that keeped old DomObject not show.
I know it possible make with innerHTML, but i wont keep DomObject, not text. Because DomObject keep many events. And it very hard for browser attach events for each DomObject after refresh area.

I have an XSD and my Data file as an input. I wish to generate .XML file out of that.
I would like to write a Java Code which should be **generic** one, i.e. it should except any .xsd and its data file to create .xml file and I don't want to change the calling setters names and calling class name when xsd changes.
In other words, i need to generate calling class as per the xsd to generate xml.
I tried JAXB to create .xml from .xsd.
For Examle:
Hello.java
import java.io.*;
import java.util.*;
import javax.xml.bind.*;
import hello.*;
public class Hello {
private ObjectFactory of;
private GreetingListType grList;
public Hello(){
of = new ObjectFactory();
grList = of.createGreetingListType();
}
public void make( String t, String l ){
GreetingType g = of.createGreetingType();
g.setText( t );
g.setLanguage( l );
grList.getGreeting().add( g );
}
public void marshal() {
try {
JAXBElement<GreetingListType> gl =
of.createGreetings( grList );
File file = new File("jaxb_hello.xml");
JAXBContext jc = JAXBContext.newInstance( "hello" );
Marshaller m = jc.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
m.marshal( gl, System.out );
m.marshal( gl, file);
} catch( JAXBException jbe ){
// ...
}
}
public static void main(String args[])
{
Hello h = new Hello();
h.make( "Bonjour, madame", "fr" );
h.make( "Hey, you", "en" );
h.marshal();
}
}
I am not sure if there exist any free library or tool on unix environment to achive this.
If there isn't any, i will try to code it down. Some references would be of great help.

Buried in Mathematica's documentation I found two references for calculating mean residual life, which I've put into similar functions.
MRL1[variable_, distribution_] := NExpectation[X \[Conditioned] X > variable,
X \[Distributed] distribution] - variable
MRL2[variable_, distribution_] := NExpectation[X - variable \[Conditioned] X > variable,
X \[Distributed] distribution]
You can find the references at:
http : //
www.wolfram.com/mathematica/new - in - 8/nonparametric - derived -
and - formula - distributions/analyze - left-- right-- and -
interval - censored - data.html
and
http://reference.wolfram.com/mathematica/ref/SkewNormalDistribution.html
The second of these corresponds in form to the third of the above definitions. One can see that the 2 functions produce the same results:
dist = LogNormalDistribution[1.75, 0.65];
var = 6;
MRL1[var, dist]
MRL2[var, dist]
4.80314
4.80314
I put together a manipulate to illustrate this idea using the first of the above functions:
dist = LogNormalDistribution[1.75, 0.65];
Manipulate[
Module[{mrl},
mrl = MRL1[t , dist];
Column[{"MEAN RESIDUAL LIFE?", " ", "PDF",
Show[ListPlot[{{t , N[PDF[dist, t ]]}, {mrl, N[PDF[dist, mrl]]}},
ImageSize -> 350,
PlotRange -> All,
Prolog -> {Text["MRL", {mrl, .01}], Text["t", {t, .02}]},
Filling -> Axis,
FillingStyle -> Lighter[Red],
AxesOrigin -> {0, 0}],
Plot[PDF[dist, x], {x, 0, 40}]],
" ",
"CDF",
Show[ListPlot[{{t , N[CDF[dist, t ]]}, {mrl, N[CDF[dist, mrl]]}},
ImageSize -> 350,
PlotRange -> All,
Prolog -> {Text["MRL", {mrl, .1}], Text["t", {t, .2}]},
Filling -> Axis,
FillingStyle -> Lighter[Red],
AxesOrigin -> {0, 0}],
Plot[CDF[dist, x], {x, 0, 40}]],
Grid[{{"t ", t}, {"MRL ", mrl}, {"Mean[dist] ",
Mean[dist]}, {"PDF at t", N[PDF[dist, t ]]}, {"CDF at t",
N[CDF[dist, t ]]}}, Alignment -> Left]}]],
{t, 0, 40}]
To put this a some context, the x axis could represent time (life expectancy, time to failure of a part) or some other quantity such as distance (miles a car runs before breaking down or how far a trend in a stock can run).
The value "t" corresponding to the x axis initializes at 0.
Some observations:
Mean[dist] = 7.10821.
Where t = 0, MRL = 7.10819 (pretty close to the mean).
As t increases towards MRL, MRL decreases.
At t = 4.7985, t = MRL (at least to 4 decimal places).
As t increases beyond MRL it drags MRL higher.
When (for this distribution) t reaches a bit over 25, MRL begins to exceed the mean of the distribution.
When I first came across mean residual life, I thought it would represent the expectation of everything beyond t and that as t increased MRL would have to increase. If someone lives to 80 years old, wouldn't they have some (if small) expectation of living longer? Some average in the tail of the distribution?
Maybe MRL doesn't make sense if t > MRL.
If 0 < t < MRL why should one's expectation be less than the mean of the distribution?
I feel a bit thick headed on this, as if I've missed some basic intuitive grasp of the idea.
I just hoped someone on the forum could give me an insight into this and how to apply it.
Thanks,
J

I find that the region where they are heading is clickable before they reach it. The animation is pretty simple, so I'm wondering if there is something obvious that I am missing in terms of telling the code to not treat the button as if it is at the final destination (I'm not sure if that is supposed to be the expected behavior and the animation is purely a visual while the clickable region is instantaneously at the destination; I wouldn't expect it to be).
Here is the code I use to animate it. It's basically switching out a sub panel and bringing back a main panel with buttons:
// switch back to main abilities panel
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration: kFadeInTime];
CGRect rect = CGRectMake(
480.0f,

Bear in mind that the data i'm responsible for is highly sensitive so any comments/feedback is much appreciated.
Here's the scenario:
1) Before file upload, files are compressed & encrypted using AES 256 with a salt.
2) Files uploaded from the clients' server over SFTP (port 22) to our SFTP server.
3) Files are then downloaded over HTTPS by our other client using one time password verification (strong 10 char alphanumeric password)
The specifics of the implementation I'm thinking of are:
For part (2) above, the connection is opened using host key matching, public key authentication and a user name/password combination. The firewall at both sides is restricted to only allow the static IP of the client server to connect.
For part (3), the other client is supplied with a user name/password on a per user basis (for auditing) to log into their jailed account on the server. the encryption password for the file itself is supplied on a per file basis, so i'm trying to apply two modes of encryption at all times here (except when the files are resting on the server).
Along with dedicated firewalls on both sides, Access control on the SFTP server will be configured to block IP addresses with a certain number of failed attempts over a short time, invalid passwords attempts will lock out users, password policies will be implemented etc.
I like to think that I've covered as much as possible but I'd love to hear what you guys think about this implementation?
For the commercial server side of things, I've narrowed it down to GloalSCAPE SFTP w/ SSH & HTTP module or JSCAPE Secure FTP server - I'll be assessing the suitability of each over the weekend but if any of you have any experience with either i'd love to hear about it also.

}

}
Watching logcat tells me that at this point, my arrayList is empty.
getNames is as follows.
public void getNames(final String mURLURLS) throws IOException {

public void run() {
try {
URL url = new URL(mURLURLS);
URLConnection con = url.openConnection();
Pattern p = Pattern.compile("text/html;\\s+charset=([^\\s]+)\\s*");
Matcher m = p.matcher(con.getContentType());
String charset = m.matches() ? m.group(1) : "ISO-8859-1";
Reader r = new InputStreamReader(con.getInputStream(), charset);
StringBuilder buf = new StringBuilder();
while (true) {
int ch = r.read();
if (ch < 0)
break;
buf.append((char) ch);
}
String strMessy = buf.toString();
strClean = new String (strMessy.replaceAll("\\<.*?>",""));
cleanArray.add(strClean);
mHandler.sendEmptyMessage(1);
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
}
The handler message calls my getFinalName method. Using the handler was the only way I could assure that the next method wouldnt get started before getName was finished.
getFinalName is as follows.
public void getFinalName(String strClean) {
//should loop through until string no longer contains any .zip files.
while (strClean.contains(".zip")){
String trimmed = strClean.substring(0, strClean.lastIndexOf(".zip"));
String[] parts = trimmed.split("\n");
String lastWord = parts[parts.length - 1] + ".zip";
finalName = lastWord;
strClean = new String(strClean.replace(finalName, ""));
linkArray.add(finalName);
}
}
Any and all ideas are appreciated, I have no clue what could be causing the arrayList to reset. At the end of getFinalName its populated, but somewhere between the end of getFinalName and getLinks, it gets reset, though theres no code between the two that is executed.

I feel like MVC .net works great for 90% of the web application types out there, but not for mine.
Basically I have a dashboard application where I'm displaying large amounts of information in many different graphs / charts (all on the same screen). If I change the state of a control on the page, say a date range, I would like all of the graphs / charts to update accordingly.
This is fairly trivial in webforms using usercontrols with ajax update panels, but I've not seen a 'good' simple implementation in MVC without doing most of the heavy lifting in JQuery / Javascript code.
Most of the examples of post backs in MVC involve a form submission (we don't have any forms on our dashboard) or it involves navigation from view to view (which I don't want to do either). The closest thing I can relate what we need to would be an MVVM framework but we won't be moving to Silverlight for a few months.
Am I thinking of MVC wrong, am I missing such a simple example that the major bloggers / tutorials don't cover it? Any thoughts?
