  • Website restyle, SEO migration plan?

    - by Goboozo
    I am currently in a project for one of my biggest clients. We have built a website that will -replace- the old website. When it comes to actual content its is largely the same. However, the presentation of the content has changed drastically. From our point of view much more user-friendly (main reason to update the site). Now, since the sites presentation has changed we have some major changes in: HTML & CSS: To change the presentation of the content URL's: To make them better understandable (301 redirects have been taken care of and are in place) Breadcrumbs: To enhance the navigation (we have made the breadcrumbs match exactly with the url's) Pagination: This was added to enable content browsing Title tags: Added descriptive title tags to the major links and buttons. Basically all user content including meta tags have remained the same. Now since this company is rather successful and 90% of its clients come from Google's organic results I am obliged to take all necessary precautions. People tell me I need a migration plan to prevent the site being hurt in Google, but I have never worked using such a plan... ...So, based on the above. Would you consider a migration plan necessary and what precautions/actions would you recommend to prevent us being put down in our SERP positions? Many thanks in advance for your answers.

  • Java game object pool management

    - by Kenneth Bray
    Currently I am using arrays to handle all of my game objects in the game I am making, and I know how terrible this is for performance. My question is what is the best way to handle game objects and not hurt performance? Here is how I am creating an array and then looping through it to update the objects in the array: public static ArrayList<VboCube> game_objects = new ArrayList<VboCube>(); /* add objects to the game */ while (!Display.isCloseRequested() && !Keyboard.isKeyDown(Keyboard.KEY_ESCAPE)) { for (int i = 0; i < game_objects.size(); i++){ // draw the object game_objects.get(i).Draw(); game_objects.get(i).Update(); //world.updatePhysics(); } } I am not looking for someone to write me code for asset or object management, just point me into a better direction to get better performance. I appreciate the help you guys have provided me in the past, and I dont think I would be as far along with my project without the support on stack exchange!

  • Where could Distributed Version Control Systems currently be in Gartner's hype cycle?

    - by dukeofgaming
    Edit: Given the recent downvoting (+8/-6 at this point) it was made clear to me that Gartner's lifecycle is a biased metric from a programmer's perspective. This is something that is part of a paper I'm going to present to management, and management types are part of Gartner's audience. Giving DVCS exposure & enthusiasm (that "could" be deemed as hype, or at least attacked as such), think about the following question when reading this one: "how could I use Gartner's hype cycle to convince management that DVCSs are ready (or ready-enough) for us, and that it is not just hype" Just asking if DVCSs is hype wouldn't be constructive, Gartner's hype cycle is a more objective instrument than just asking that (even if this instrument is regarded as biased). If you know any other instrument please, by all means, mention it. Edit #2: I agree that Gartner's Life Cycle is not for every technology, but I consider it may have generated enough buzz to be considered hype by some, so it maybe deserves to be at least evaluated/pondered as such by using this instrument in order to prove/disprove it to whatever degree. I'm an advocate of DVCS, BTW. I'm doing research for a whitepaper I'm writing in favor of DVCS adoption at company and I stumbled upon the concept of social proof. I want to prove that the social proof of DVCS adoption is not necessarily cargo cult and doing further research I now stumbled upon Gartner's hype cycle which describes technology maturity in 5 phases. My question is: what could be an indicator of the current location of Distributed Version Control Systems (I mean git, mercurial, bazaar, etc. in general) at a particular phase in the hype cycle?... in other (less convoluted) words, would you say that currently expectations of DVCSs are a) starting, b)inflated, c)decreasing (disillusionment), d)increasing (enlightenment) or e)stabilizing (mature) and (more importantly) why? I know it is a hard question and there is subjectivity involved, but I'll grant the answer (and the traditional cookie) to the clearest argument/evidence for a particular phase.

  • Windows Firewall: How to allow traffic on port 8080?

    - by Chadworthington
    I am trying to configure team Foundation Server so that 1) it is accessible from within my Home Network 2) and then make the Web site access accessible via the Internet I have a problem with point 1: When I access http://192.168.1.106:8080/tfs/web/ locally from 192.168.1.106, it works. When I access the same web site from another PC in my home network, the abive URL works only if I turn of the Firewall on 192.168.1.106. Can someone please tell me specifically how to allow traffic on port 8080 without turning off Windows Firewall? It seems that the exceptions that I specify are intended for listing programs on the box that need to communicate out. Is IIS the program that I need to make the exception? How do I specify that port 8080 traffic should be allowed for web site traffic on this port? I hope to have success with pt. 2 later but I figure (1) should be done first. I expect issues.

  • Getting MTP to work with a Galaxy tab 2 7.0?

    - by Wouter
    I'm trying to get MTP with the galaxy tab 2 7.0 working on my ubuntu installation. Such that I can access the files. I tried to do what is described here: http://www.omgubuntu.co.uk/2011/12/how-to-connect-your-android-ice-cream-sandwich-phone-to-ubuntu-for-file-access I however fail at executing one of the following commands mtp-detect | grep idVendor mtp-detect | grep idProduct This fails [20:42|0] $ mtp-detect | grep idVender Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7310/P7510/N7000/I9100/Galaxy Tab 7.7/10.1/S2/Nexus/Note. PTP_ERROR_IO: failed to open session, trying again after resetting USB interface LIBMTP libusb: Attempt to reset device LIBMTP PANIC: failed to open session on second attempt Unable to open raw device 0 [20:44|0] $ mtp-detect | grep idProduct Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7310/P7510/N7000/I9100/Galaxy Tab 7.7/10.1/S2/Nexus/Note. PTP_ERROR_IO: failed to open session, trying again after resetting USB interface LIBMTP libusb: Attempt to reset device LIBMTP PANIC: failed to open session on second attempt Unable to open raw device 0 Now my guess was was that the idVender is the same as the VID (04e8) and the idProduct is the same as PID (6860) Now I continued to work with those values and completed the tutorial. When finished I tried android-connect This returned fuse: bad mount point `/media/GalaxyTab': Transport endpoint is not connected Does anybody have a clue what to do? Also I want to note that when I connect my GalaxyTab 2 7.0 that I still get a pop-up of ubuntu that a device was connected. I also can still see the mapstructure, the problem however is is that all the folders have 0 bytes and do not have any subfolders. I can only see the folders in the root. ps. I also checked a similar question and tried what is described in this answer http://askubuntu.com/a/88630/27480

  • Is Movable Type among the most secure PHP blogs? How secure are the various PHP blog applications?

    - by user6025
    Basically I'm trying to find a blog for a website, and security is the highest priority in our case. We don't need any features that I would imagine are special. Wordpress was our first idea, but its reputation precedes it, and though it may have cleaned up its act lately, I'm not seeing much solid evidence. I get the impression that Movable Type (at least the Perl version) has a much better reputation for security than Wordpress (historically at least). I'm not sure I want to take a chance with Wordpress at this point, but is there some objective source I can got to to back up (or counter) the notion that MT is at least among the best? Secunia doesn't recommend using their stats for comparisons, and securityfocus.com doesn't have stats at all that I can see. Searching here http://web.nvd.nist.gov makes MT look way better than WP (at least in 2007), but this site was referenced by MT's own page boasting about their security, so I don't know how relevant it is or how seriously people take it. Any suggestions on sites where I could/should make a somewhat objective comparison?

  • How to manage a developer who has poor communication skills

    - by djcredo
    I manage a small team of developers on an application which is in the mid-point of its lifecycle, within a big firm. This unfortunately means there is commonly a 30/70 split of Programming tasks to "other technical work". This work includes: Working with DBA / Unix / Network / Loadbalancer teams on various tasks Placing & managing orders for hardware or infrastructure in different regions Running tests that have not yet been migrated to CI Analysis Support / Investigation Its fair to say that the Developers would all prefer to be coding, rather than doing these more mundane tasks, so I try to hand out the fun programming jobs evenly amongst the team. Most of the team was hired because, though they may not have the elite programming skills to write their own compiler / game engine / high-frequency trading system etc., they are good communicators who "can get stuff done", work with other teams, and somewhat navigate the complex beaurocracy here. They are good developers, but they are also good all-round technical staff. However, one member of the team probably has above-average coding skills, but below-average communication skills. Traditionally, the previous Development Manager tended to give him the Programming tasks and not the more mundane tasks listed above. However, I don't feel that this is fair to the rest of the team, who have shown an aptitute for developing a well-rounded skillset that is commonly required in a big-business IT department. What should I do in this situation? If I continue to give him more programming work, I know that it will be done faster (and conversly, I would expect him to complete the other work slower). But it goes against my principles, and promotes the idea that you can carve out a "comfortable niche" for yourself simply by being bad at the tasks you don't like.

  • redirect on a Domino HTTP server?

    - by oidsman
    Simple question but:- We have a server running Domino Http server on port 80. We have another apache server running on 8081. We want to set a DNS entry (say 'Things') to point to a page on the 8081 server. As I see it we need to do some kind of redirect on the Domino server to say that any traffic from hostname 'Things' gets a redirect to "http://server:8081/content/". So, in summary, if I type in "http://Things" on my browser I get redirected to "http://server:8081/content/" Does anyone know how to do this on the Domino Http server? Thanks in advance for your help!

  • How can I force Parallels' networking to obtain an IP through a wireless router?

    - by RLH
    Here is my setup. I have a Macbook, Thunderbolt display and an Ethernet connection plugged into the Thunderbolt display. During the day, most of my network use can (and should) operate across the ethernet associated with my display. However, I also need to be able to connect up to a wireless router. This hasn't been a problem on the Mac OS X side, but the program that I need to run on the router has to obtain an IP address from the wireless access point. Considering my current setup, how can I leave it so that I can access the internet in OS X, yet have my Window 7 instance running in Parallels, get it's assigned IP address from a wireless router that my Mac is also connected to? I've fiddled around with the Parallel's network settings for an hour, and I can't get Parallel's to see the router, even though my Mac is certainly connected to it.

  • Booting sequence. Ubuntu 12.04 installation and cohabitation with former OSes

    - by Stephane Rolland
    I am on the brink of installing Ubuntu 12.04 Precise Pengolin on the first primary partition of my hard-drive. (A day in History for me since I had always kept a MS windows at this first place). But I have some fears: This is my last computer available (In the past I used to have 2 or even 3 machines so I could always un/plug HDs for recovery operations and rescue) The current booting sequence is not straight forard. So as to explain the boot sequence let me briefly sum-up the history of this laptop computer. It was a dedicated Windows Vista computer. 1st and only Primary partition. Then I added Windows 7 (on the 2nd primary partition) letting the Windows Vista Boot Loader manage the boot sequence. Then I added Ubuntu 10.04 Lucid Lynx on the 1st sub-partition of the Extended Partitionm asking Grub to be the boot loader. But when I ask Grub to launch windows it launches the Vista BootLoader that manages the choice betzeen Vista and 7. So in theory Grub is on the MasterBootRecord - though I understand where the Vista BootLoader remains. Now, I will no longer use the Ubuntu 10.04 ( on extended partition) and also the Windows vista (on the first primary partition). I will install Ubuntu 12.04 on the First Primary, asking it to install a new bootloader. I want to keep the Windows 7 that is already on the Second Primary partition. And I want it to be loaded by the Ubuntu Boot loader(I don4t knoz zhich is included in this version)... And I am afraid the last point will not work.

  • USB Device first mounted as root, then by user

    - by Petr Marek
    When I connect my Kindle, it shows up as an usb0 media, which I can read but not write (owner = root). However, if I do sudo umount /media/usb0, usb0 gets unmounted and a Kindle media gets mounted properly (is writable etc.). What can cause such strange behavior? It's not only with Kindle, but with Flash drives etc. as well. My /etc/fstab: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

  • 12.04 No Sound - ALC888 / Radeon 3200HD

    - by Ross
    Evening all. I have a MSI U230 netbook, MV40 processor, 4Gb RAM with integrated ATI Radeon 3200HD grahics & an ALC888 codec integrated soundcard. It has HDMI out as well. I've tried a few distro's and have been around linux for a short time. I reckon I've settled on Ubuntu 12.04 (32bit) due to it doing pretty much everything I want it to. I'm working with a fresh install right now. I recently re-installed when I was going in circles trying to solve my problem before. I install Ubuntu and it works, except for the sound. I have tried things like reinstalling Alsa, editing my asound.conf file, installing HDA Verb and a few other things. Its at the point where I need to ask for help... Some outputs: ross@ross:~$ aplay -l ** List of PLAYBACK Hardware Devices ** card 0: SB [HDA ATI SB], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 ross@ross:~$ uname -r 3.2.0-34-generic-pae ross@ross:~$ lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780M/RS780MN [Mobility Radeon HD 3200 Graphics] ross@ross:~$ lspci | grep Audio 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) 01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS780 HDMI Audio [Radeon HD 3000-3300 Series] Added options snd-hda-intel position_fix=1 to alsa-base.conf file Unmuted all in alsamixer Can anyone suggest anything more?

  • Using an Apt Repository for Paid Software Updates

    - by Scott Warren
    I'm trying to determine a way to distribute software updates for a hosted/on-site web application that may have weekly and/or monthly updates. I don't want the customers who use the on-site product to have to worry about updating it manually I just want it to download and install automatically ala Google Chrome. I'm planning on providing an OVF file with Ubuntu and the software installed and configured. My first thought on how to distributed software is to create six Apt repositories/channels (not sure which would be better at this point) that will be accessed through SSH using keys so if a customer doesn't renew their subscription we can disable their account: Beta - Used internally on test data to check the package for major defects. Internal - Used internally on live data to check the package for defects (dog fooding stage). External 1 - Deployed to 1% of our user base (randomly selected) to check for defects. External 9 - Deployed to 9% of our user base (randomly selected) to check for defects. External 90 - Deployed to the remaining 90% of users. Hosted - Deployed to the hosted environment. It will take a sign off at each stage to move into the next repository in case problems are reported. My questions to the community are: Has anyone tried something like this before? Can anyone see a downside to this type of a procedure? Is there a better way?

  • Setting up routing for MS DirectAccess to a VMWare EsXi Host

    - by Paul D'Ambra
    I'm trying to set up DirectAccess on a virtual machine so I can demonstrate it's value and then if need be add a physical machine to host it. I'm hitting a problem because the Direct Access machine (DA01) needs to have 2 public addresses actually configured on the external adapter but there is a Zyxel Zywall USG300 between the VMware ESXi host and the outside world. I've summarised my setup in this diagram If I ping from the LAN to 212.x.y.89 I get a response but if I ping from the VM I get destination host unreachable. I used "route add 212.x.y.89 192.c.d.1" and get request timed out. At that point I see outbound traffic allowed on the Zyxel firewall but nothing coming back. I'm past my understanding of routing and VMWare so am not sure how to tie down where my problem lies (or even if this setup is possible). So any help massively appreciated. Paul

  • Physically moving a hard drive from older iMac (c2d) to new iMac (i7) ?

    - by Inshim
    Instead of my usual habit of using superduper to mirror my drive to a new computer, I just physically moved the hard drive from an older iMac to a new one. But... it now doesn't boot, getting stuck at the apple logo screen. Since the hard drive that came with the new iMac works well, and my old drive works well when I return it to the older iMac, I conclude that there is some problem at the system/kernel level due to the different hardware. In the past I did similar things (e.g. starting a C2D machine from a Core Duo in target disk mode), so perhaps the change in architecture to the i5/i7 is too problematic? The main point: do you know of any way to get the system to rebuild for itself the proper versions of the system components when booting? Are there certain directories that I can safely delete to make that happen? Thanks

  • Is it possible to do a full Android backup without first rooting the phone?

    - by Howiecamp
    I'm running stock 2.1 on my Moto Droid and am interested in rooting. My (admittedly weak at this point) understanding is that, in order to perform a backup[*], you need to root first. But in order to root, you've got to replace the 2.1 image with a rooted 2.0.1 or a stock 2.0.1 and then a rooted 2.1. So there's no CYA protection given that you've got to take the risk of replacing the image in order to get root and then do a backup. [*] Ideally, I'd like to backup the stock 2.1 image AND my apps. Am I understanding this correctly, or is there a way to do a backup without first replacing the image?

  • starting nginx via upstart

    - by Chiggsy
    Background: DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.04 DISTRIB_CODENAME=lucid DISTRIB_DESCRIPTION="Ubuntu 10.04 LTS" I've built nginx, and I'd like to use upstart to start it: nginx upstart script from the site: description "nginx http daemon" start on runlevel 2 stop on runlevel 0 stop on runlevel 1 stop on runlevel 6 console owner exec /usr/sbin/nginx -c /etc/nginx/nginx.conf -g "daemon off;" respawn I get "unknown job" when i try to use initctl to run it, which I just learned apparently means there is an error, ( what's wrong with "Error" to describe errors?) Can someone point me in the right direction ?

  • problem with crating table on phpMyAdmin database

    - by tombull89
    Hello all, I'm running a phpMyAdmin Database on my web package on a 1and1-hosted server. I've managed to set up a database in the control panel, have uploaded all to root/phpmyadmin and changed the config.ini.php file to point at 1and1's database server (because that's the way they do it). I can go to the web interface and get to the main page, but all it shows is the database name and I can't find how to create any tables. I know it's a long shot but I'm almost out of ideas. Also, 1and1 have their own phpmyadmin panel, which is pretty annoying to use, and a 1and1 webdatabase which I have barely looked at. Help and suggestions much appriciated.

  • Portable scripting language for a multi-server admin?

    - by Aaron
    Please Note: Portable as in portableapps.com, not the traditional definition. Originally posted on stackoverflow.com, asking here at another user's suggestion. I'm a DBA and sysadmin, mostly for Windows machines running SQL Server. I'm looking for a programming/scripting language for Windows that doesn't require Admin access or an installer, needing no install process other than expanding it into a folder. My intent is to have a language for automation on which I can standardize. Up to this point, I've been using a combination of batch files and Unix shell, using sh.exe from UnxUtils but it's far from a perfect solution. I've evaluated a handful of options, all of them have at least one serious shortcoming or another. I have a strong preference for something open source or dual license, but I'm more interested in finding the right tool than anything else. Not interested that anything that relies on Cygwin or Java, but at this point I'd be fine with something that needs .NET. Requirements: Manageable footprint (1-100 files, under 30 MB installed) Run on Windows XP and Server (2003+) No installer (exe, msi) Works with external pipes, processes, and files Support for MS SQL Server or ODBC connections Bonus Points: Open Source FFI for calling functions in native DLLs GUI support (native or gtk, wx, fltk, etc) Linux, AIX, and/or OS X support Dynamic, object oriented and/or functional, interpreted or bytecode compiled; interactive development Able to package or compile scripts into executables So far I've tried: Ruby: 148 MB on disk, 23000 files Portable Python: 54 MB on disk, 2800 files Strawberry Perl: 123 MB on disk, 3600 files REBOL: Great, except closed source and no MSSQL or ODBC in free version Squeak Smalltalk: Great, except poor support for scripting ---- cut: points of clarification ---- Why all the limitations? I realize some of my criteria seem arbitrarily confining. It's primarily a product my environment. I work as a SQL Server DBA and backup Unix admin at a division of a large company. In addition to near a hundred boxes running some version or another of SQL Server on Windows, I also support the SQL Server Express Edition installs on over a thousand machines in the field. Because of our security policies, I don't login rights on every machine. Often enough, an issue comes up and I'm given local Admin for some period of time. Often enough, it's some box I've never touched and don't have my own environment setup yet. I may have temporary admin rights on the box, but I'm not the admin for the machine- I'm just the DBA. I've no interest in stepping on the toes of the Windows admins, nor do I want to take over any of their duties. If I bring up "installing" something, suddenly it becomes a matter of interest for Production Control and the Windows admins; if I'm copying up a script, no one minds. The distinction may not mean much to the readers, but if someone gets the wrong idea I've suddenly got a long wait and significant overhead before I can get the tool installed and get the problem solved. That's why I want something that can be copied and run in the manner of a portable app. What about the small footprint? My company has three divisions, each in a different geographical location, and one of them is a new acquisition. We have different production control/security policies in each division. I support our MSSQL databases in all three divisions. The field machines are spread around the US, sometimes connecting to the VPN over very slow links. Installing Ruby \using psexec has taken a long time over these connections. In these instances, the bigger time waster seems to be archives with thousands and thousands of files rather than their sheer size. You could say I'm spoiled by Unix, where the admins usually have at least some modern scripting language installed; I'd use PowerShell, but I don't know it well and more importantly it isn't everywhere I need to work. It's a regular occurrence that I need to write, deploy and execute some script on short notice on some machine I've never on which logged in. Since having Ruby or something similar installed on every machine I'll ever need to touch is effectively impossible because of the approvals, time and and Windows admin labor needed I makes more sense find a solution that allows me to work on my own terms.

  • How to use BT or emule across 2 or more hard drives?

    - by the searcher
    One difficulty with BT or emule is that, when the hard drive is full, we constantly need to move older files to a new hard drive so that we can download newer files. We can change BT or emule's setting so that the folder for downloading points to the new hard drive, but then, what if emule haven't finished downloading for some files that are hard to find, and it is 92% done... in that case, we would like to keep the old setting so that when the last 8% arrives, it can go into the correct file. (and same for BT, if we haven't finished some file or if we want to seed something later). So is there a good way to let BT or emule point to 2 hard drives, or somehow let the new hard drive "merge" into the existing hard drive / folder?

  • Lockup when unlocking screen saver

    - by chris
    I've had this happen a couple of times - screen saver kicks in, locks the screen, and when I put my password in to unlock it the system just seems to hang. Cursor turns to the busy, HDD light flickers occasionally, but the only thing I can do at that point is power down. This is on a desktop, not a laptop and according to the bios all the power saving is turned off. Has anyone else seen this? Is there a way to prevent it, or at least diagnose the cause?

  • Are there videocamera which geotag individual frames?

    - by Grzegorz Adam Hankiewicz
    I'm looking for a way to record live video with the specific requirement of having each frame georeferenced with GPS. Right now I'm using a normal video camera with a PDA+GPS that records the position, but it's difficult to sync both of these plus sometimes I've forgotten to turn the PDA+GPS or it has failed for some reason and all my video has been useless. Using google I found that about two years ago a company named Seero produced such video cameras and software, but apparently the domain doesn't exist any more and I only find references of other pages mentioning it. Does somebody know of any other product? I need to record this video in HD and have some way to export to Google Maps or other GIS software the positions of the frames in a way that I can click on the map and see what was being recorded in the video at that point. The precission of the GPS tracking is good enough as one position per second, intermediate frames of the video stream can be interpolated.

  • Tuning Default WorkManager - Advantages and Disadvantages

    - by Murali Veligeti
    Before discussing on Tuning Default WorkManager, lets have a brief introduction on What is Default WorkManger Before Weblogic Server 9.0 release, we had the concept of Execute Queues. WebLogic Server (before WLS 9.0), processing was performed in multiple execute queues. Different classes of work were executed in different queues, based on priority and ordering requirements, and to avoid deadlocks. In addition to the default execute queue, weblogic.kernel.default, there were pre-configured queues dedicated to internal administrative traffic, such as weblogic.admin.HTTP and weblogic.admin.RMI.Users could control thread usage by altering the number of threads in the default queue, or configure custom execute queues to ensure that particular applications had access to a fixed number of execute threads, regardless of overall system load. From WLS 9.0 release onwards WebLogic Server uses is a single thread pool (single thread pool which is called Default WorkManager), in which all types of work are executed. WebLogic Server prioritizes work based on rules you define, and run-time metrics, including the actual time it takes to execute a request and the rate at which requests are entering and leaving the pool.The common thread pool changes its size automatically to maximize throughput. The queue monitors throughput over time and based on history, determines whether to adjust the thread count. For example, if historical throughput statistics indicate that a higher thread count increased throughput, WebLogic increases the thread count. Similarly, if statistics indicate that fewer threads did not reduce throughput, WebLogic decreases the thread count. This new strategy makes it easier for administrators to allocate processing resources and manage performance, avoiding the effort and complexity involved in configuring, monitoring, and tuning custom executes queues. The Default WorkManager is used to handle thread management and perform self-tuning.This Work Manager is used by an application when no other Work Managers are specified in the application’s deployment descriptors. In many situations, the default Work Manager may be sufficient for most application requirements. WebLogic Server’s thread-handling algorithms assign each application its own fair share by default. Applications are given equal priority for threads and are prevented from monopolizing them. The default work-manager, as its name tells, is the work-manager defined by default.Thus, all applications deployed on WLS will use it. But sometimes, when your application is already in production, it's obvious you can't take your EAR / WAR, update the deployment descriptor(s) and redeploy it.The default work-manager belongs to a thread-pool, as initial thread-pool comes with only five threads, that's not much. If your application has to face a large number of hits, you may want to start with more than that.Well, that's quite easy. You have  two option to do so.1) Modify the config.xmlJust add the following line(s) in your server definition : <server> <name>AdminServer</name> <self-tuning-thread-pool-size-min>100</self-tuning-thread-pool-size-min> <self-tuning-thread-pool-size-max>200</self-tuning-thread-pool-size-max> [...] </server> 2) Adding some JVM parameters Add the following system property in setDomainEnv.sh/setDomainEnv.cmd or startWebLogic.sh/startWebLogic.cmd : -Dweblogic.threadpool.MinPoolSize=100 -Dweblogic.threadpool.MaxPoolSize=100 Reboot WLS and see the option has been taken into account . Disadvantage: So far its fine. But here there is an disadvantage in tuning Default WorkManager. Internally Weblogic Server has many work managers configured for different types of work.  if we run out of threads in the self-tuning pool(because of system property -Dweblogic.threadpool.MaxPoolSize) due to being undersized, then important work that WLS might need to do could be starved.  So, while limiting the self-tuning would limit the default WorkManager and internally it also limits all other internal WorkManagers which WLS uses.So the best alternative is to override the default WorkManager that means creating a WorkManager for the Application and assign the WorkManager for the application instead of tuning the Default WorkManager.

  • help with Outlook Exchange server and curl

    - by stib
    I work on a mac in a building full of PCs, and the IT department here doesn't have IMAP access turned on on the exchange servers. So I miss a lot of meetings because I don't get reminders because I access my mail via Outlook Web access. I had written a script to scrape my Outlook Web Access calendar and turn it into iCal format, so I could get my reminders via thunderbird or iCal.app. It basically downloaded the calendar page via curl, parsed the HTML and reformatted all the appointments as ical. it wasn't elegant, but it worked. Then they changed to outlook 2007, and it doesn't work any more. I have a sketchy knowledge of curl, and almost zero knowledge of how outlook works. Can anyone point me towards a reference for getting calendar info out of an exchange server without using outlook? If I can configure curl to get the HTML I will be happy, but if there's a more elegant way, such as getting the calendar info as XML I'll be delirious.

  • Stir Trek 2: Iron Man Edition

    Next month (7 May 2010) Ill be presenting at the second annual Stir Trek event in Columbus, Ohio. Stir Trek (so named because last year its themes mixed MIX and the opening of the Star Trek movie) is a very cool local event.  Its a lot of fun to present at and to attend, because of its unique venue: a movie theater.  And whats more, the cost of admission includes a private showing of a new movie (this year: Iron Man 2).  The sessions cover a variety of topics (not just Microsoft), similar to CodeMash.  The event recently sold out, so Im not telling you all of this so that you can go and sign up (though I believe you can get on the waitlist still).  Rather, this is pretty much just an excuse for me to talk about my session as a way to organize my thoughts. Im actually speaking on the same topic as I did last year, but the key difference is that last year the subject of my session was nowhere close to being released, and this year, its RTM (as of last week).  Thats right, the topic is Whats New in ASP.NET 4 how did you guess? Whats New in ASP.NET 4 So, just what *is* new in ASP.NET 4?  Hasnt Microsoft been spending all of their time on Silverlight and MVC the last few years?  Well, actually, no.  There are some pretty cool things that are now available out of the box in ASP.NET 4.  Theres a nice summary of the new features on MSDN.  Here is my super-brief summary: Extensible Output Caching use providers like distributed cache or file system cache Preload Web Applications IIS 7.5 only; avoid the startup tax for your site by preloading it. Permanent (301) Redirects are finally supported by the framework in one line of code, not two. Session State Compression Can speed up session access in a web farm environment.  Test it to see. Web Forms Features several of which mirror ASP.NET MVC advantages (viewstate, control ids) Set Meta Keywords and Description easily Granular and inheritable control over ViewState Support for more recent browsers and devices Routing (introduced in 3.5 SP1) some new features and zero web.config changes required Client ID control makes client manipulation of DOM elements much simpler. Row Selection in Data Controls fixed (id based, not row index based) FormView and ListView enhancements (less markup, more CSS compliant) New QueryExtender control makes filtering data from other Data Source Controls easy More CSS and Accessibility support Reduction of Tables and more control over output for other template controls Dynamic Data enhancements More control templates Support for inheritance in the Data Model New Attributes ASP.NET Chart Control (learn more) Lots of IDE enhancements Web Deploy tool My session will cover many but not all of these features.  Theres only an hour (3pm-4pm), and its right before the prize giveaway and movie showing, so Ill be moving quickly and most likely answering questions off-line via email after the talk. Hope to see you there! Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.
