• Modifying Exchange 2003 accounts in Exchange 2010 management console?

  - by MartinC

  You can look at Exchange 2003 accounts via the 2010 Management console but is modifying supported? No warnings that it is not, and all is held in Active Directory. Adding an additional email address works... But results in Error 4, Keywords "classic" Task Get-MailboxStatistics writing error when processing record of index 0. Error: Microsoft.Exchange.Management.Tasks.MdbAdminTaskException: Mailbox 'domain/OU/account name' doesn't exist in an Exchange 2007 or later mailbox database. Management Console has the updated change, as does ADUC in 2003.

• what's the difference between DEFAULT_SIZE and PREFERRED_SIZE?

  - by CD1

  hi, I'm using Swing GroupLayout and I'm confused about the values GroupLayout.DEFAULT_SIZE and GroupLayout.PREFERRED_SIZE. I never know when to use each one of them in methods like GroupLayout.addComponent(Component, int, int, int). suppose I have this code: GroupLayout l = ...; l.setHorizontalGroup(l.createSequentialGroup() .addComponent(tf1) .addComponent(tf2)); l.setVerticalGroup(l.createParallelGroup() .addComponent(tf1) .addComponent(tf2)); there are two JTextFields on a single line laid out with GroupLayout (one sequential group horizontally and one parallel group vertically). if I resize the window now, both components get the available space (50% each). but I want only the first text field to grow/shrink horizontally and only the second text field to grow/shrink vertically. what values of min, pref and max should I use to accomplish that? I know I can just try it and see what combination works but I'd like to know the reasoning behind this problem.

• What to use to wait on a indeterminate number of tasks?

  - by Scott Chamberlain

  I am still fairly new to parallel computing so I am not too sure which tool to use for the job. I have a System.Threading.Tasks.Task that needs to wait for n number number of tasks to finish before starting. The tricky part is some of its dependencies may start after this task starts (You are guaranteed to never hit 0 dependent tasks until they are all done). Here is kind of what is happening Parent thread creates somewhere between 1 and (NUMBER_OF_CPU_CORES - 1) tasks. Parent thread creates task to be run when all of the worker tasks are finished. Parent thread creates a monitoring thread Monitoring thread may kill a worker task or spawn a new task depending on load. I can figure out everything up to step 4. How do I get the task from step 2 to wait to run until any new worker threads created in step 4 finish?

• Erlang Question - Time order of messages

  - by Aiden Bell

  Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and(answered below) is there any guarantee of order when processing messages? ie. Received in order sent? If so, how is clock skew handled in high traffic situations for ordering? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

• Why isn't it possible to update an ObservableCollection from a different thread?

  - by MainMa

  In a multi-threaded WPF application, it is not possible to update an ObservableCollection from a thread other than WPF window thread. I know there are workarounds, so my question is not how to avoid the "This type of CollectionView does not support changes to its SourceCollection from a thread different from the Dispatcher thread" exception. My question is, why there is such an exception? Why wasn't it possible to allow collection updates from any thread? Personally, I don't see any reason to block UI update when ObservableCollection is changed from other threads. If two threads (including parallel ones) are accessing the same object, one listening for changes of object properties through events, the other one doing changes, it will always work, at least if locks are used properly. So, what are the reasons?

• Linux (lsusb) not showing String Descriptors of a USB device

  - by tzippy

  I have an embedded device that when plugged to a linux host, shows up with vid and pid that are not in the usb.ids file (proprietary IDs). However I provide String Descriptors that do show up when plugged into a Windows Host. But not on a Linux Host. lsusb -v shows only iManufacturer 3 iProduct 2 iSerial 1 But on the device side, when processing the setup requests, I see that the Strings are actually requested by the Host. By Windows and also the Linux Host. The USB Device Tree Viewwer under Windows shows this output: iManufacturer : 0x01 Language 0x0409 : "My Manufacturer" iProduct : 0x02 Language 0x0409 : "MyProduct" iSerialNumber : 0x03 Language 0x0409 : "My Serial" I feel that lsusb does not show all of the information. Is there a more informative tool?

• How to move file pointer to a particular location using fseek()?

  - by Noge

  My intention is to read every elements in the 2nd column into a buffer[] from the following .txt file: 9992891234 09.920 15.771 11.909 9992345971 07.892 12.234 09.234 9992348971 64.567 70.456 50.987 9992348231 89.234 85.890 58.982 I have know of a way to do it by using fscanf(): for (int i=0;i<4;i++) { fscanf(pFile, "%lld", &junk); fscanf(pFile, "%f", &buffer[i]); fscanf(pFile, "%f", &junk); fscanf(pFile, "%f", &junk); } However, since I'm doing parallel programing which requires me to use different Windows Threads to read different columns, so I'll need to read the elements in the 2nd column directly using fseek(). The question here is, what should I put in the 2nd argument in fseek() in the code below to move my file pointer to read the 2nd element of the 2nd line? fscanf(pFile, "%llf", &junk);//<------this is used to skip the 1st data for (int i=0;i<4;i++) { fscanf(pFile, "%f", &buffer[i]); fseek ( pFile , ??, SEEK_CUR );//<----how do I calculate this offset? }

• How much ram to be able to convert large (5-6MB) jpegs? [closed]

  - by cosmicbdog

  I've got a project where we want to be processing large jpegs (5-6MB) with apache and php (using GD library). My understanding is that the server converts the image into a BMP making it quite ram heavy and currently we're unable to do it with our 1gb of memory. Here's the error we get: Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 17408 bytes) How much ram should we be looking at running with to process images of this size? Edit: As Chris S the purist highlighted below, my post is apparently vague. I am doing the most basic and common manipulation of an image, say turning it from a 4352px x 3264px jpg of 5mb in size, to a 900px x 675px file.

• Isolating read and write in multithreaded

  - by the_lotus

  Hi In a multithreaded application. I have a bunch of function that loop through a collection to read the information. I also have a bunch of function that modifies that same collection. I’m looking for a way to isolate all the read and the write together. I don’t want a write to be done while a read is in progress. I was thinking of using SyncLock on the collection object but this will block multiple read trying to work in parallel.

• How do I stop my IIS App Pool making a request to wpad.mydomain.com?

  - by Programming Hero

  As part of some performance troubleshooting, I've monitored the slow startup of a "cold" App Pool (one without an active worker process) in IIS. When using a built-in account, the App Pool starts in sub-second time. When using a custom local account the App Pool takes 30+ seconds to start processing requests. The service appears to be making requests to wpad.mydomain.com, an address it does not have access to, which causes it to wait 30 seconds for a response before eventually timing out. As a workaround, I've added the hostname to the server's hosts file, to direct the traffic to the local machine, which returns much faster (1-2 seconds). What do I need to do to stop IIS making this request when this identity is used for the App Pool?

• Faster s3 bucket duplication

  - by Sean McCleary

  I have been trying to find a better command line tool for duplicating buckets than s3cmd. s3cmd can duplicate buckets without having to download and upload each file. The command I normally run to duplicate buckets using s3cmd is: s3cmd cp -r --acl-public s3://bucket1 s3://bucket2 This works, but it is very slow as copies each file via the API one at a time. If s3cmd could run in parallel mode, I'd be very happy. Are there other options available as a command line tools or code that people use to duplicate buckets that are faster than s3cmd?

• PHP CPU utilization limit

  - by knightrider

  I have done some research on the net regarding the problem. My questions is NOT how to reduce cpu utilization by improving algorithm or improving the performance by using multitasking or limiting CPU per system user. I have a website where user logs in does some processing and logout. The site uses linux server, php and apache. The problem is that I cant control the amount of CPU allocated to each user. ie I want give a guarantee that a user will get say atleast 5% of CPU (assume total number of users is less than 20). How can I do this? Any solution (A php code, apache server settings, or any out of box soln) is welcomed. Thankyou very much for reading this :)

• Why doesn't disabling IE's 'Protected Mode' enable the dragging-and-dropping of addresses from the IE address bar into Notepad

  - by dumbledad

  IE's Protected Mode prevents one dragging the address from the IE address bar into other applications (for example Notepad). There's an informative article on MSDN about Allowing Drag and Drop Operations in your Application. If I uncheck Enable Protected Mode in IE's settings and restart IE I still cannot drag the address from the IE address bar into other Notepad. Why doesn't disabling IE's 'Protected Mode' enable the dragging-and-dropping of addresses from the IE address bar into Notepad? Is there a way to make that work without adding a registry entry for Notepad (following the instructions in the article I mentioned)? (N.B. This is actually part of me trying to work out how to get this address drag-and-drop working in Processing.)

• How can you buffer two online videos alternately while playing one of them?

  - by Rajats1234

  On my website, I want my user to be able to launch video 2 at any point in the middle of video 1 without waiting or refreshing the window. How can I buffer the two videos such that I buffer video 1 enough to let it start playing, and then buffer just enough of video 2 that if the user launches it at any point, he does not have to wait to view its first few seconds, and then I can come back and buffer the rest of video 1? If this is not possible, I could also look at buffering video 1 and 2 in parallel while playing only video 1. Thanks!

• For very beginning startup: home server or EC2?

  - by StCee

  The micro instance of Amazon EC2 only has ram of 613MB, my laptop got 8GB. And I suppose likewise the processing power of my computer would be better than the micro instance. My question is, what are the considerations in deciding to host yourself or on Amazon EC2, especially for a really baby startup? For example, would network speed be a problem? My computer broadband network is 100Mbs up to 1Gbs. What would Amazon compare to this? My site at these moment would just host some images and perform some php requests. I would probably also use cloudflare but seems it increases the dns lookup time considerably... And of course the overall objective is to make the best user experience.

• Server Overload Due To Log File

  - by emresavas

  cPanel sent me the following email: IMPORTANT: Do not ignore this email. This is cPanel stats runner on ***.***.com! While processing the log files for user ***, the cpu has been maxed out for more than a 6 hour period. The current load/uptime line on the server at the time of this email is 04:41:14 up 15 days, 22:36, 0 users, load average: 7.66, 7.84, 8.00 You should check the server to see why the load is so high and take steps to lower the load. If you want stats to continue to run even with a high load; Edit /var/cpanel/cpanel.config and change extracpus to a number larger then 0 (run /usr/local/cpanel/startup afterwards to pickup the changes). How can I lower the load?

• C# Spawn Multiple Threads for work then wait until all finished

  - by pharoc

  just want some advice on "best practice" regarding multi-threading tasks. as an example, we have a C# application that upon startup reads data from various "type" table in our database and stores the information in a collection which we pass around the application. this prevents us from hitting the database each time this information is required. at the moment the application is reading data from 10 tables synchronously. i would really like to have the application read from each table in a different thread all running in parallel. the application would wait for all the threads to complete before continuing with the startup of the application. i have looked into BackGroundWorker but just want some advice on accomplishing the above. Does the method sound logical in order to speed up the startup time of our application How can we best handle all the threads keeping in mind that each thread's work is independent of one another, we just need to wait for all the threads to complete before continuing. i look forward to some answers

• Personally identifiable information (PII) on shared web hosting

  - by S. Cobbs

  Hey folks, I am providing web hosting services (shared and dedicated) and have had one of my shared hosting clients mention needing an SSL cert for their site where they are collecting insurance quotes in a form, including names and social security numbers. My privacy sense is tingling, and I'm pretty sure it's not legal (in the US) to do this on a shared system, but can't find anything to support my thoughts outside of PCI-DSS, but the customer isn't processing payments through the site so I'm not sure if that applies. I'm reading lots of policy documents where people advise to minimize and manage the PII footprint internally, but as the host I don't want to put all of my customer's clients at possible risk. I'm not looking here for legal advice necessarily, but perhaps someone in a similar position to mine can provide some rule of thumb or point me in the right direction.

• What is the best way to sync multiple client SqlServers to one MS SqlServer 2005?

  - by user605055

  I have several client databases that use my windows application. I want to send this data for online web site. The client databases and server database structure is different because we need to add client ID column to some tables in server data base. I use this way to sync databases; use another application and use C# bulk copy with transaction to sync databases. My server database sql server is too busy and parallel task cannot be run. I work on this solution: I use triggers after update, delete, insert to save changes in one table and create sql query to send a web service to sync data. But I must send all data first! Huge data set (bigger than 16mg) I think can't use replication because the structure and primary keys are different.

• Mysql: how do I make an exact working copy of a table?

  - by epo

  I am working on a restructuring of a legacy database and its associated applications. To keep old and new working in parallel I have created a development database and copied the tables of interest to it, e.g. create database devdb; drop table if exists devdb.tab1; CREATE TABLE devdb.tab1 like working.tab1; insert into devdb.tab1 select * from working.tab1; Having done this I notice that triggers affecting tab1 have not been copied over. Is there any way in which I can produce a working copy of tab1, i.e. data, permissions, triggers, everything?

• Detecting when a process has finished (but not exited)

  - by Egwor

  I have a program that's run in unix (that I have no control over) that when finished prints 'Completed successfully' but does not exit. I want to automatically detect when the process finishes (by checking the output of the command), so that I can kill the process and so that I can proceed do other activities. The complexity comes because I want to be able to run multiples of these scripts concurrently. (One activity I need to do requires the script to be called with various inputs, but each time the script runs it takes a while to return, and so I want to do them in parallel) Has anyone done something similar to this? I could redirect the stderr and stdout output of the command to a temporary file which has a random file name, then tail the file and pipe to grep for the end conditions (I.e. the certain log lines). The problem is, surely tail -f would keep running, and so it would never exit. Should I poll? If so, what's the best approach?

• Mac OS X 10.5 VNC Resolution independent of hardware display

  - by Qberticus

  Is it possible to set the VNC display resolution that is independent of the hardware resolution when you are using OS X 10.5 Screen Sharing? I have a macbook and a windows box with 3 monitors. I'd like to use the 3 monitors on my windows box to do work on my macbook when I'm at my desk. When I VNC into the macbook I only get the resolution of the hardware screen (1280x800). Instead I'd like to use two of my monitors on my windows box to display a large VNC screen from my macbook. The scaling options in the VNC clients (TightVNC and Ultr@VNC) do not adjust the actual resolution of the display they just do image processing. My ultimate goal is for someway to have a virtual display on my windows box that is from my macbook that is independent of the macbook's hardware screen.

• What factors can affect performance of Http Server written in C-Sharp? [on hold]

  - by Yousaf

  I am having trouble in terms of handling huge databases. I have multiple clients like 100-300 (clients are basically servers with i.e windows sql). Each client may have 38 thousand rows/listing of data, each row has 10-12 fields. I cannot afford to have json files of each client and than handle them on main server, because of memory issue. What if i have http server written in c or c# installed on clients and they return 250 rows in each response to the main server. How the factors like speed, memory or other issues can effect us ? What exactly I am asking for ? In short words if a server writter in c-sharp sends 250 rows per request. What factors can effect the performance of server ? for example. Speed, processing, Operating system, Implementation of algorithm of server ? How these factors can really effect the performance on large scale?
