  • SSL HandShake on Java Client

    - by JKV
    I have a very basic doubt in SSL HandShake. Assume that we have a server S which uses self signed certificates. I write a Java client C which connects to the S. When C connects to S, C gets certificates from S and saves them to its truststore and the remaining part of the communication proceeds. After some time I use the same C to connect to the S, so will S send the certificates again to C, or C will use the certificates already stored in truststore. I am not good in SSL and underlying implementation of Truststore functionality in Java. Will S send the certificates to C invariable of whether the C has certificates on its truststore?? I believe that if I have certificates in truststore C trusts S and C will not ask for certificates when I connect again?? Is my assumption right?? Is the process same for self-signed certificates and CA certificates?? Thanks in advance.

  • Storing Shell Output

    - by Emil Radoncik
    Hello everybody, I am trying to read the output of a shell command into a string buffer, the reading and adding the values is ok except for the fact that the added values are every second line in the shell output. for example, I have 10 rows od shell output and this code only stores the 1, 3, 5, 7, 9, row . Can anyone point out why i am not able to catch every row with this code ??? any suggestion or idea is welcomed :) import java.io.*; public class Linux { public static void main(String args[]) { try { StringBuffer s = new StringBuffer(); Process p = Runtime.getRuntime().exec("cat /proc/cpuinfo"); BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream())); while (input.readLine() != null) { //System.out.println(line); s.append(input.readLine() + "\n"); } System.out.println(s.toString()); } catch (Exception err) { err.printStackTrace(); } } }

  • Ruby: Is there a better way to iterate over multiple (big) files?

    - by zxcvbnm
    Here's what I'm doing (sorry for the variable names, I'm not using those in my code): File.open("out_file_1.txt", "w") do |out_1| File.open("out_file_2.txt", "w") do |out_2| File.open_and_process("in_file_1.txt", "r") do |in_1| File.open_and_process("in_file_2.txt", "r") do |in_2| while line_1 = in_1.gets do line_2 = in_2.gets #input files have the same number of lines #process data and output to files end end end end end The open_and_process method is just to open the file and close it once it's done. It's taken from the pickaxe book. Anyway, the main problem is that the code is nested too deeply. I can't load all the files' contents into memory, so I have to iterate line by line. Is there a better way to do this? Or at least prettify it?

  • ruby on rails params injection

    - by Julien P.
    Hello everyone, I have a question about ruby on rails and the process of assigning variables using the params variable passed through a form class User attr_accessible :available_to_admins, :name end Let's say that I have a field that is only available to my admins. Assuming that you are not an admin, I am going to not display the available_to_admins input in your form. After that, when I want to save your data I'll just do a: User.update_attributes(params[:user]) If you are an admin, then no problem, the params[:user] is going to contain name and available_tu_admins and if you're not then only your name. Since the available_to_admins is an attr_accessible parameter, how should I prevent non admin users from being able to inject a variable containing the available_to_admins input with their new value?

  • Difference between "traditional" COM and COM+ (in Component Services)

    - by kizzx2
    By the "traditional" way I mean registering the DLL in registry. There seems to be another method to set up it by going to mmc-Component Services-COM+ Applications and adding the .tlb file. I have a COM library that supports both methods. When it installs, it registers itself in the registry as a COM component and it works fine. However, when I added the .tlb file using the Component Services method, the behavior seems to be different and it starts giving out errors. I suspect it has something to do with marshaling and inter-process object transfer? (Sorry, I'm really a noob in the COM area) Can anyone point me to a good resource to clear my understanding?

  • How to use AIR 2.0 NativeProcess API with Java?

    - by dede
    How do you use this great new API in connection with Java? Do you use just pure native process API like nativeProcess.standardInput.write() and nativeProcess.standardOutput.read() with which you cannot debug Java side neither invoke remote java method. Or you are using some library that leverages remote method invocation such as flerry lib but that also cannot debug Java side? Or maybe you are using Merapi with which you can debug but cannot remotely invoke Java method? I'm asking this because this is maybe the most important question regarding this API and its ease of use.

  • Star-schema: Separate dimensions for clients and non-clients or shared dimension for attendants?

    - by celopes
    I'm new to modeling star schemas, fresh from reading the Data Warehouse Toolkit. I have a business process that has clients and non-clients calling into conference calls with some of our employees. My fact table, call it "Audience", will contain a measure of how long an attending person was connected to the call, and the cost per minute of this person's connection to the call. The grain is "individual connection to the conference call". Should I use my conformed Client dimension and create a non-client dimension (for the callers that are not yet clients) this way (omitting dimensions that are not part of this questions): Or would it be OK/better to have a non-conformed Attending dimension related to the conformed Client dimension in this manner: Or is there a better/standard mechanism to model business processes like this one?

  • Avoiding improper std::string initialization with NULL const char* using g++

    - by pachanga
    A there any g++ options which can detect improper initialization of std::string with NULL const char*? I was in the process of turning some int fields into std::string ones, i.e: struct Foo { int id; Foo() : id(0) {} }; ...turned into: struct Foo { std::string id; Foo() : id(0) {} //oooops! }; I completely overlooked bad 'id' initialization with 0 and g++ gave me no warnings at all. This error was detected in the run time(std::string constructor threw an exception) but I'd really like to detect such stuff in the compile time. Is there any way?

  • Mootools not loading fast enough IE6

    - by Tom
    Very random and annoying problem with IE6. We keep our common JS files on a resources server so we only have to update them in one place. As well as our custom classes we also keep our build of mootools and more on the resources server and link to it in the head of our sites. This is fine in all the browsers accept IE6. In IE6 it seems to not loads the core quick enough from the external link before trying to process the mootools code in my site.js file. It will go wrong on the first line "windows.addEvent". If i put a mootools core in a folder where the site is though its fine. Does anyone know why it might be doing this and if so a way around it, but still keeping the files on the resources domain? Thanks Tom

  • Adhoc Data processing / ETL

    - by Dane
    I've just started at a new company in outsourced communications (e.g. print and mail, email, fax). One of the requirements is to process clients data and get it ready for mailing. For recurring jobs, this is easy using an ETL tool linked in with some addressing software, but for adhoc stuff it's a bit overkill. I've used inhouse developed stuff before (clunky but usable), but I don't want to have to re-develop that here. Any recommendations? Some features : Basic DBMS functionality (preferably with a proper DBMS backend for SQL support) Field concatenation (e.g. combine Firstname + Surname) "Pushing columns" (e.g. with address fields 1 - 8, push them left so if one is blank, the next one gets pushed up) Australia post mail sorting and dpid allocation (or can link into external tools relatively easily)

  • add schema to path in postgresql

    - by veilig
    I'm the process of moving applications over from all in the public schema to each having their own schema. for each application, I have a small script that will create the schema and then create the tables,functions,etc... to that schema. Is there anyway to automatically add a newly created schema to the search_path? Currently, the only way I see is to find the users current path SHOW search_path; and then add the new schema to it SET search_path to xxx,yyy,zzz; I would like some way to just say, append schema zzz to the users_search path. is this possible?

  • JPA and MySQL transaction isolation level

    - by armandino
    I have a native query that does a batch insert into a MySQL database: String sql = "insert into t1 (a, b) select x, y from t2 where x = 'foo'"; EntityTransaction tx = entityManager.getTransaction(); try { tx.begin(); int rowCount = entityManager.createNativeQuery(sql).executeUpdate(); tx.commit(); return rowCount; } catch(Exception ex) { tx.rollback(); log.error(...); } This query causes a deadlock: while it reads from t2 with insert .. select, another process tries to insert a row into t2. I don't care about the consistency of reads from t2 when doing an insert .. select and want to set the transaction isolation level to READ_UNCOMMITTED. How do I go about setting it in JPA?

  • Creating a MSI patch (.msp) by hand?

    - by Jerry Chong
    Our team has recently been considering pushing out a minor registry fix to users to modify one particular problematic key. Pretty straightforward stuff, just needed to update 1 key/value inside the registry. So at the moment, we are using Wix to build .msi installers for the product. While looking into Wix's support for generating .msp patch files, it seems that the only way to create an .msp is a somewhat overcomplicated multi-step process to: Get a copy of the original MSI, and compile a new copy of the fixed MSI Write a new Wix file that points to both installers Compile the Wix file into a .wixobj with Candle to a .psp Run Torch/Pyro over before/after snapshots of the original installers and the .psp, or alternatively using MsiMsp.exe Now my question is, can't I simply describe the registry change into a Wix file and directly compile it into the .msp, without step 1 and 4 - which is a huge amount of effort for just a simple change?

  • Is there a way to list all the database queries my wordpress install is making for a given event?

    Using a method similar to the one described here: (http://stackoverflow.com/questions/14873/how-do-i-display-database-query-statistics-on-wordpress-site), I can see the total number of queries being made when I load a page. Now I'd like to output a list of the queries that are being made when the page loads. This would allow me to see who my biggest resource hogs are without having to go through the process of elimination of all my plugins and theme scripts. How would I do this? Thanks.

  • Best way to implement a Rest API with PHP on Wamp web server

    - by DomingoSL
    Hello, i own a web server running windows (WAMP). I want to know the best way to implement a Rest API (a very simple one) in order to let a user do something. Diagram flow: I have programming skills, in fact, i developed some time ago a web server in VB6 who process the querys and when it find the command (http:/serverIP/webform.php?cmd=run&item=any) it do something, but know i really want to develop a solution using the WAMP server. Some people consider the solution of executing a exe when a command is detected a bad solution for security issues, but this specific proyect i have is for the use of only some people (trusted people) who dont have intentions of hacking the server. So, what do you think? Remember: Its not a public API, its for some people and some programs who will use the API Its a very simple one, only one command using POST or GET. Thanks

  • Chart Control Inside SSRS ReportViewer is Viewable From Localhost But Not Internet

    - by Daniel Coffman
    A project I own was just moved from an older server to a new one, and in the process of moving the web folder, re-deploying the SSRS reports, restoring the database, configuring IIS, etc... I have lost the ability to view the Microsoft Chart Controls that are embedded in the SSRS reports, that are then displayed by a Microsoft.ReportViewer. I could view them both locally and remotely (via the internet) on the old server. I can view them if I preview the SSRS report in Visual Studio. The report displays fine, only missing all the embedded charts. I can still view them locally through the web browser, just not from the internet. What am I missing? I tried giving permissions to the ChartImageHandler temp storage folder, but it didn't work. I'm getting the Javascript error: Error: ClientReport380ec8ca0c294a809e9986c1bef9db1c is undefined

  • How to work with BufferedImage and YCbCr colorspace?

    - by Onlyx
    Hi everyone! I need to translate colors in bitmap loaded to BufferedImage from RGB to YCbCr (luminance and 2 channels chrominance) and back after process. I made it with functions used like rgb2ycbcr() in main method for each pixel, but it isn't so smart solution. I should use ColorSpace and ColorModel classes to get BufferedImage with correct color space. It would be more flexible method, but I don't know how to do that. I'm lost and I need some tips. Can somebody help me?

  • What ports does Advantage Database Server need?

    - by asherber
    I have an application which uses ADS and I am attempting to deploy it in a Windows network environment with a rather restrictive firewall. I am having a problem configuring firewall ports appropriately. ADS lives on \server, and it's listening on port 1234. When \client tries to connect to \server\tables, I get Error 6420 (Discovery process failed). When \client tries to connect to \server:1234\tables, I get error 6097, bad IP address specified in the connection path. \server is pingable from \client, and I can telnet to \server:1234. If I try to connect from a client machine inside the firewall, either connection path works fine. It seems there must be something else I need to open in the firewall. Any ideas? Thanks, Aaron.

  • Is there a way to convert a swf to an .abc file?

    - by Jeremy Ruppel
    I'm looking for a way, preferably a command-line utility, to pump out an .abc file for a compiled swf. I've looked into asc.jar, but so far it seems like it can only accept classes, not compiled swfs. Anybody know of a good way to do this? The end-goal of this process is to use Zwetan's RedTamarin project to run describeType on some specific classes inside a loaded swf, but there are complications with SecurityDomain preventing me from using Loader.loadBytes. If there's another good way to describe classes in the loaded swf via command-line, I'd be interested in that solution as well. Cheers, J

  • Can I create object names from a text file in Python 2.7?

    - by user560100
    I'm working on a game project. I've created an object, Star(Object). I want to assign the name of the variables, dynamically, from a text file. If I have a text file with: Sol Centauri Vega I want the program to create the Star(Object) with variable names from the text file. I want the process automated, because I'm looking to create hundreds of stars. I could write the code out by hand: Sol = Star(Sol) Centauri = Star(Centauri) Vega = Star(Vega) But isn't there a way to automate this? Essentially, what I eventually want is a tuple with the list of stars, as their own objects. Then, when I am doing game maintenance, I can just iterate over all the objects in the tuple.
