• UML binary association aggregatee has access to aggregator

  - by user314172

  Firstly, I'd like to thank those who answered my previous question ages ago. Currently I'm engaging more in the design phase UMLs, as this is my first medium scale deployment I'm entrusted with. This is extremely simple, but it bugs me so. If (Component) owns (Manager of Component), and (Manager of Component) has a reference to (Component) through which it manages it; how do you fully describe the relationship? I know it is aggregative, but how do you describe (Manager of Component) possessing a reference/pointer to the (Component) that physically owns the (Manager of Component) ? Example: Lidar owns a LidarManager

• Differences between extension methods in C#3 & 4

  - by Buh Buh

  I think I remember reading a long time ago that in C#3 extension methods could only be applied to primitive types and interfaces; and that in C#4 they could be used to extend any type. This doesn't seam to match up with what I am seeing now and I am finding it difficult to find this documented. Is there any truth to this or did my memory make it all up? What are the rules relating to which types can be extended? Are there any differences between C# 3 and 4?

• How to call a method in another class in Java?

  - by Puchatek

  Currently I have two classes. a classroom class and a School class. I would like to write a method in the School class to call public void setTeacherName(String newTeacherName) from the classroom class. public class classroom { private String classRoomName; private String teacherName; public void setClassRoomName(String newClassRoomName) { classRoomName = newClassRoomName; } public String returnClassRoomName() { return classRoomName; } public void setTeacherName(String newTeacherName) { teacherName = newTeacherName; } public String returnTeacherName() { return teacherName; } } import java.util.ArrayList; public class School { private ArrayList<classroom> classrooms; private String classRoomName; private String teacherName; public School() { classrooms = new ArrayList<classroom>(); } public void addClassRoom(classroom newClassRoom, String theClassRoomName) { classrooms.add(newClassRoom); classRoomName = theClassRoomName; } // how to write a method to add a teacher to the classroom by using the classroom parameter // and the teachers name }

• Java reflection Method invocations yield result faster than Fields?

  - by omerkudat

  I was microbenchmarking some code (please be nice) and came across this puzzle: when reading a field using reflection, invoking the getter Method is faster than reading the Field. Simple test class: private static final class Foo { public Foo(double val) { this.val = val; } public double getVal() { return val; } public final double val; // only public for demo purposes } We have two reflections: Method m = Foo.class.getDeclaredMethod("getVal", null); Field f = Foo.class.getDeclaredField("val"); Now I call the two reflections in a loop, invoke on the Method, and get on the Field. A first run is done to warm up the VM, a second run is done with 10M iterations. The Method invocation is consistently 30% faster, but why? Note that getDeclaredMethod and getDeclaredField are not called in the loop. They are called once and executed on the same object in the loop. I also tried some minor variations: made the field non-final, transitive, non-public, etc. All of these combinations resulted in statistically similar performance. Edit: This is on WinXP, Intel Core2 Duo, Sun JavaSE build 1.6.0_16-b01, running under jUnit4 and Eclipse.

• How do I write in-code comments and documentation in a proper way? Is there any standard for this?

  - by hkBattousai

  I want to add documentation in my code by means of comment lines. Is there any standard format for this? For example, consider the code below: class Arithmetic { // This method adds two numbers, and returns the result. // dbNum1 is the first number to add, and dbNum2 is second. // The returning value is dbNum1+dbNum2. static double AddTwoNumbers(double dbNum1, double dbNum2); } For this example code, is there any better way of writing the comment lines?

• Websphere 5.1 add SSL certificate

  - by Mikhail

  Hi All. I have the following instruction: Import ++++ certificate (in order to allow SSL connections) – it is done in Administrative Console for the corresponding WAS profile (Security-SSL certificate and key management-Key stores and certificates-NodeDefaultTrustStore-Signer certificates). Here you can simply add the attached trkd_cert.cer (“Add” button) or get it from port (“Retrieve from port” button, host: ++++.com, port 443) But this is valid for Websphere 6.1. Do somebody know how this can be done in WebSphere 5.1?

• jQuery relative positioned hover

  - by danixd

  I want a link to the next or previous image to appear when hovering over the main image, only I want the next link to appear when hovered over the right hand side, and previous on the left. I have looked at jQuery's .position() and I don't think I am understanding it very well. At the moment all I have is general mouseenter/mouseleave events, which show both links when the image is hovered. jQuery(document).ready(function($) { $('.nav-controls a').hide(); $('#slideshow').mouseenter(function() { $('.nav-controls a').fadeIn(500); }); $('#slideshow').mouseleave(function() { $('.nav-controls a').fadeOut(500); }); }); I'd image it to be something like: jQuery(document).ready(function($) { $('.nav-controls a').hide(); var image = $('#slideshow'); var left = image.position().left(0); var right = image.position().left(50%); left.mouseenter(function() { $('.nav-controls a.previous').fadeIn(500); }); left.mouseleave(function() { $('.nav-controls a.previous').fadeOut(500); }); right.mouseenter(function() { $('.nav-controls a.next').fadeIn(500); }); right.mouseleave(function() { $('.nav-controls a.next').fadeOut(500); }); }); Not sure if I should be using position, if I am using it correctly. Any tips would be great. Edit: I do not want to add unnecessary markup in the form of divs, for the left/right selectors.

• Android : How to use flurry API

  - by SWDeveloper

  Hi All, I am using flurry in my app, and I am new to that. I have some doubts. My requirement is, In my main activity I will start a session, and calling onevent method in some activities. And I am not calling endSeesion method anywhere. I want to know when the FlurryAgent will hit the flurry site. So do I need to call endSession then where should I call that method? How FlurryAgent maintains the session. In case if I call like this FlurryAgent.onEndSession(this); FlurryAgent.onStartSession(this, Constants.FLURRY_API); FlurryAgent.setLogEnabled(true); will it work like this - previous session will be closed and new session will be started. I can track only http urls using fiddler, when I try to track https calls then its getting crashed, I have modified ssl settings in fiddler, I dont know how to configure my emulator. Thanks in Advance.

• PresentModalViewController from within UISplitViewController: weird behavior in landscape mode

  - by Krumelur

  Hi, I've been using PresentModalViewController a lot and never had any issues. But when showing a modal controller from within any controller hosted by a UISplitViewController I get strange orientation bugs. In my table view (which is root controller of the UISplitView), when a cell is touched, I call: MyController oModal = new MyController(); oModal.ModalPresentationStyle = UIModalPresentationStyle.FormSheet; oModal.ModalTransitionStyle = UIModalTransitionStyle.CrossDissolve; this.PresentModalViewControll(oModal, true); If the iPad is in Portrait, all is okay. If it is in landscape however, the modal controller fades in but its orientation is incorrect. Then, after fading in has finished, it suddenly flips 90 degrees and adjusts to correct orientation. I have overriden ShouldAutoRotateToInterfaceOrientation(), so that cannot be it. Ideas? René

• retrieve cobol s9(2) COMP onto C variable

  - by Pablo Cazallas

  Hi, I need to retrieve data from a COBOL variable of the type: "PIC S9(2) COMP" onto a C variable of the type "int". It's stored using two bytes of a string, so I receive it as a couple of chars. I know COBOL stores decimal data onto a "S9(2) COMP" in binary format, so It would be a great help letting me know any algorithm or way to convert it safely. Any kind of help & suggestion will be welcome. Thanks in advance and regards, Pablo.

• Two SSL certificates required for two Apache servers using mod_proxy to serve HTTPS?

  - by Nick

  Our application originally used a single Apache server with mod_perl installed to serve up all HTTPS requests. Due to memory issues I've added a lighter Apache installation and used ProxyPass to hand off the Perl requests to the mod_perl enabled server. We currently have an SSL certificate installed on the mod_perl server but I'm struggling to understand whether we need a certificate for both servers or only the lightweight server which is receiving the original requests. Or can a certificate be used for more than one server on a single machine? Thanks in advance for any help/pointers.

• Automating silent software deployments on Solaris 10

  - by datSilencer

  Hello everyone. Essentially, the question I'd like to ask is related to the automation of software package deployments on Solaris 10. Specifically, I have a set of software components in tar files that run as daemon processes after being extracted and configured in the host environment. Pretty much like any server side software package out there, I need to ensure that a list of prerequisites are met before extracting and running the software. For example: Checking that certain users exists, and they are associated with one or many user groups. If not, then create them and their group associations. Checking that target application folders exist and if not, then create them with preconfigured path values defined when the package was assembled. Checking that such folders have the appropriate access control level and ownership for a certain user. If not, then set them. Checking that a set of environment variables are defined in /etc/profile, pointed to predefined path locations, added to the general $PATH environment variable, and finally exported into the user's environment. Other files include /etc/services and /etc/system. Obviously, doing this for many boxes (the goal in question) by hand can be slow and error prone. I believe a better alternative is to somehow automate this process. So far I have thought about the following options, and discarded them for one reason or another. 1) Traditional shell scripts. I've only troubleshooted these before, and I don't really have much experience with them. These would be my last resort. 2) Python scripts using the pexpect library for analyzing system command output. This was my initial choice since the target Solaris environments have it installed. However, I want to make sure that I'm not reinveting the wheel again :P. 3) Ant or Gradle scripts. They may be an option since the boxes also have java 1.5 enabled, and the fileset abstractions can be very useful. However, they may fall short when dealing with user and folder permissions checking/setting. It seems obvious to me that I'm not the first person in this situation, but I don't seem to find a utility framework geared towards this purpose. Please let me know if there's a better way to accomplish this. I thank you for your time and help.

• Weird nfs performance: 1 thread better than 8, 8 better than 2!

  - by Joe

  I'm trying to determine the cause of poor nfs performance between two Xen Virtual Machines (client & server) running on the same host. Specifically, the speed at which I can sequentially read a 1GB file on the client is much lower than what would be expected based on the measured network connection speed between the two VMs and the measured speed of reading the file directly on the server. The VMs are running Ubuntu 9.04 and the server is using the nfs-kernel-server package. According to various NFS tuning resources, changing the number of nfsd threads (in my case kernel threads) can affect performance. Usually this advice is framed in terms of increasing the number from the default of 8 on heavily-used servers. What I find in my current configuration: RPCNFSDCOUNT=8: (default): 13.5-30 seconds to cat a 1GB file on the client so 35-80MB/sec RPCNFSDCOUNT=16: 18s to cat the file 60MB/s RPCNFSDCOUNT=1: 8-9 seconds to cat the file (!!?!) 125MB/s RPCNFSDCOUNT=2: 87s to cat the file 12MB/s I should mention that the file I'm exporting is on a RevoDrive SSD mounted on the server using Xen's PCI-passthrough; on the server I can cat the file in under seconds ( 250MB/s). I am dropping caches on the client before each test. I don't really want to leave the server configured with just one thread as I'm guessing that won't work so well when there are multiple clients, but I might be misunderstanding how that works. I have repeated the tests a few times (changing the server config in between) and the results are fairly consistent. So my question is: why is the best performance with 1 thread? A few other things I have tried changing, to little or no effect: increasing the values of /proc/sys/net/ipv4/ipfrag_low_thresh and /proc/sys/net/ipv4/ipfrag_high_thresh to 512K, 1M from the default 192K,256K increasing the value of /proc/sys/net/core/rmem_default and /proc/sys/net/core/rmem_max to 1M from the default of 128K mounting with client options rsize=32768, wsize=32768 From the output of sar -d I understand that the actual read sizes going to the underlying device are rather small (<100 bytes) but this doesn't cause a problem when reading the file locally on the client. The RevoDrive actually exposes two "SATA" devices /dev/sda and /dev/sdb, then dmraid picks up a fakeRAID-0 striped across them which I have mounted to /mnt/ssd and then bind-mounted to /export/ssd. I've done local tests on my file using both locations and see the good performance mentioned above. If answers/comments ask for more details I will add them.

• Different SVN Serverversions and Clients

  - by lueda

  Hi, we are going to migrate from CVS to SVN using subversion 1.6. But also we have another SVN-Server using subversion 1.2 (no chance to update). So we plan to use the newer TortoiseSVN 1.6.x Is it possible to use two different servers while using only the new TortoiseSVN? Another solution may be using an old TortoiseSVN compiled against subversion 1.2. Is this possible? What about using two TortoiseSVN (1.2.x and 1.6.x)?

• How to close all background processes in unix?

  - by Gabi Purcaru

  I have something like: cd project && python manage.py runserver & cd utilities && ./coffee_auto_compiler.py And I want both of them to close on Ctrl-C (or some other command). How can I accomplish that? EDIT: I tried using jobs -x kill and kill `jobs -p `, but it doesn't seem to kill what I need. Here is what I mean: moon 8119 0.0 0.0 7556 3008 pts/0 S 13:17 0:00 /bin/bash moon 8120 6.8 0.4 24568 18928 pts/0 S 13:17 0:00 python manage.py runserver jobs -p give me just process 8119, but I also need to close 8120, since it's the thing that the first command opened. If it helps, the commands are actually in a Makefile, and I want it to run two daemons at the same time (and somehow close them at the same time). And yes, I'm using ubuntu, with bash

• VPN authentication and MAC addresses

  - by zakk

  I have to set up a VPN (various clients connecting to a web service on a server, which is also the VPN server) and I want to make sure that no user will share his/her credentials with third parties. I know that this problem is not solvable completely, but I'd want to set up some additional security checks... Some idea I have: 1) An additional check on MAC address, but... are MAC addresses preserved thru VPN? 2) Some kind of extra identification of the client (User Agent, open ports, I want to make sure that is the very same client I authorized). 3) I would like to avoid commercial solutions like a security token... I realize it would be the perfect solution, but it will be to expensive, I suppose... Do you feel that these options are viable? Do you have any other ideas? Thanks in advance for your replies!

• External USB attached drive works in Windows XP but not in Windows 7. How to fix?

  - by irrational John

  Earlier this week I purchased this "N52300 EZQuest Pro" external hard drive enclosure from here. I can connect the enclosure using USB 2.0 and access the files in both NTFS partitions on the MBR partitioned drive when I use either Windows XP (SP3) or Mac OS X 10.6. So it works as expected in XP & Snow Leopard. However, the enclosure does not work in Windows 7 (Home Premium) either 64-bit or 32-bit or in Ubuntu 10.04 (kernel 2.6.32-23-generic). I'm thinking this must be a Windows 7 driver problem because the enclosure works in XP & Snow Leopard. I do know that no special drivers are required to use this enclosure. It is supported using the USB mass storage drivers included with XP and OS X. It should also work fine using the mass storage support in Windows 7, no? FWIW, I have also tried using 32-bit Windows 7 on both my desktop, a Gigabyte GA-965P-DS3 with a Pentium Dual-Core E6500 @ 2.93GHz, and on my early 2008 MacBook. I see the same failure in both cases that I see with 64-bit Windows 7. So it doesn't appear to be specific to one hardware platform. I'm hoping someone out there can help me either get the enclosure to work in Windows 7 or convince me that the enclosure hardware is bad and should be RMAed. At the moment though an RMA seems pointless since this appears to be a (Windows 7) device driver problem. I have tried to track down any updates to the mass storage drivers included with Windows 7 but have so far come up empty. Heck, I can't even figure out how to place a bug report with Microsoft since apparently the grace period for Windows 7 email support is only a few months. I came across a link to some USB troubleshooting steps in another question. I haven't had a chance to look over the suggestions on that site or try them yet. Maybe tomorrow if I have time ... ;-) I'll finish up with some more details about the problem. When I connect the enclosure using USB to Windows 7 at first it appears everything worked. Windows detects the drive and installs a driver for it. Looking in Device Manager there is an entry under the Hard Drives section with the title, Hitachi HDT721010SLA360 USB Device. When you open Windows Disk Management the first time after the enclosure has been attached the drive appears as "Not initialize" and I'm prompted to initialize it. This is bogus. After all, the drive worked fine in XP so I know it has already been initialized, partitioned, and formatted. So of course I never try to initialize it "again". (It's a 1 GB drive and I don't want to lose the data on it). Except for this first time, the drive never shows up in Disk Management again unless I uninstall the Hitachi HDT721010SLA360 USB Device entry under Hard Drives, unplug, and then replug the enclosure. If I do that then the process in the previous paragraph repeats. In Ubuntu the enclosure never shows up at all at the file system level. Below are an excerpt from kern.log and an excerpt from the result of lsusb -v after attaching the enclosure. It appears that Ubuntu at first recongnizes the enclosure and is attempting to attach it, but encounters errors which prevent it from doing so.

Today I recieved a 1394b 9 pin to 1394a 6 pin cable which allowed me to connect the "EZQuest Pro" via Firewire. Everything works. When I use Firewire I can connect whether I'm using Windows 7 or Ubuntu 10.04. I even tried booting my Gigabyte desktop as an OS X 10.6.3 Hackintosh and it worked there as well. (Though if I recall correctly, it also worked when using USB 2.0 and booting OS X on the desktop. Certainly it works with USB 2.0 and my MacBook.) I believe the firmware on the device is at the latest level available, v1.07. I base this on the excerpt below from the OS X System Profiler which shows Firmware Revision: 0x107. Bottom line: It's nice that the enclosure is actually usable when I connect with Firewire. But I am still searching for an answer as to why it does not work correctly when using USB 2.0 in Windows 7 (and Ubuntu ... but really Windows 7 is my biggest concern).

• Word caption style

  - by Theodor

  This should be a common problem for anyone involved in technical writing. When you insert an image (or table etc.) caption in Word, you get this dialog. You enter your caption, in this case "A happy bicycle" (in yellow). This might be fine for a happy bicycle, but I want to have captions that have one style for the "enumeration" and one style for the description, as such: I have tried searching for this but I haven't found anything yet...

• What is the best way to secure MySQL data on a laptop *without* whole-disk-encryption?

  - by GJ

  I need to have the mysql data on my laptop stored in an encrypted state so that in case of the laptop being lost/stolen it will extremely difficult to recover the data without the password. I don't wish to use whole disk encryption, due to the performance impact it will have on other disk-intensive programs' usage. What could be the ideal solution for me balancing security and performance? Thanks!
