  • Vim */dyn support

    - by galymzhan
    What does mean the plus sign before */dyn in the :version command's output, e.g.: +python/dyn +python3/dyn +ruby/dyn +tcl/dyn I didn't find any useful documentation on it. When I run :echo has('python3') Vim returns 0. When I run :python3 print('hi') it says E370: Could not load library python31.dll meaning I should install python (as I understand). So I just can't see the difference between -*/dyn and +*/dyn. What does plus sign give to us? Also what's the difference from dyn-less feature, e.g. +python?

  • ssl between balancer members?

    - by jemminger
    I have apache running on one machine as a load balancer: <VirtualHost *:443> ServerName ssl.example.com DocumentRoot /home/example/public SSLEngine on SSLCertificateFile /etc/pki/tls/certs/example.crt SSLCertificateKeyFile /etc/pki/tls/private/example.key <Proxy balancer://myappcluster> BalancerMember http://app1.example.com:12345 route=app1 BalancerMember http://app2.example.com:12345 route=app2 </Proxy> ProxyPass / balancer://myappcluster/ stickysession=_myapp_session ProxyPassReverse / balancer://myappcluster/ </VirtualHost> Note that the balancer takes requests under SSL port 443, but then communicates to the balancer members on a non-ssl port. Is it possible to have the forwarding to the balancer members be under SSL too? If so, is this the best/recommended way? If so, do I have to have another SSL cert for each balancer member? Does the SSLProxyEngine directive have anything to do with this?

  • Oracle Products Reflect Key Trends Shaping Enterprise 2.0

    - by kellsey.ruppel(at)oracle.com
    Following up on his predictions for 2011, we asked Enterprise 2.0 veteran Andy MacMillan to map out the ways Oracle solutions are at the forefront of industry trends--and how Oracle customers can benefit in the coming year. 1. Increase organizational awareness | Oracle WebCenter Suite Oracle WebCenter Suite provides a unique set of capabilities to drive organizational awareness. In particular, the expansive activity graph connects users directly to key enterprise applications, activities, and interests.

  • More than 3 seconds "Initial Connection" time (webpagetest.org)

    - by George Tasioulis
    I'm having a weird issue with a vBulletin forum, on a 2? Xeon E5645 w/ 16GB RAM, cPanel and LiteSpeed webserver; It takes too long to start loading... When I tested it with webpagetest.org I saw that for every request there's a 3 second "Initial connection" delay, which I don't know why is happening. Here's a screenshot: CPU Load is between 0.03 and 0.05, I've got several GB of free RAM, practical no I/O activity, and this delay can occur even with only one visitor on the forum. Where do you suggest I start searching? What could be the reason for this kind of delay? I don't think it's the webserver, or the forum because there's another website on the server (total 2 sites) which is WordPress based, and has exactly the same issue with the 3 second initial connection delay. I believe it's OS related, but need a clue on where to start looking. Thanks in advance :)

  • LibreOffice Calc/Writer: How to get the dates for specifc weekdays per month?

    - by Phin
    I'm stuck with a problem in LibreOffice Calc or Writer: I try to get a table of dates for every monday, wednesday and friday per month, something that I can load every new month wich sets the dates automatically so I just have to print the page on paper. :) In Writer the fieldcommand for date can't obviosly do the job (it only can be set to a fix date, the todays date or +offset as far as I can see). In Calc I tried it with the autofill but that obviosly works for the first 3 days only. I might add that I'm lost with Excel/calc formulars... Any help?

  • Cannot find my hard disk while installing linux-“No root file system defined” error

    - by Syam Kumar S
    I am trying install Linux on my computer (tried Ubuntu 10.4 and Linux Mint 9). I started the installation wizard and on the hard disk selection page the hard disk is not displayed. I have a 500GB disk with 5 partitions and windows 7 ultimate in one partition. If I click the forward button, it shows an error- "No root file system defined". I have tried to install by booting from CD and pendrive but both shows the same error. When I load Linux as live CD it doesn't show the hard disk. My hard disk works fine in windows 7. System config: intel i3 2100, 500GB hdd, 2GB ram

  • Cannot boot from USB on my Mac mini

    - by Thai Tran
    Two weeks ago I installed OSX 10.8 on my Mac mini. After that, my system started to hang a lot, so I tried to erase it and install OSX 10.7 again. I used carbon Copy Cloner to make the bootable USB and it can load successfully on another Macbook. However, on my Mac mini, when I press on the option button to select the USB, it loads the white screen with a ban symbol at the center of the screen. After a moment, my machine automatically shuts down. Does anyone know how to solve this problem? Edit: this is exactly the problem I have now http://forums.macrumors.com/archive/index.php/t-1207168.html Update 1: the hdd seems ok (from disk utility). I restored the booting partition by disk utility (drag the dmg file to that partition). After restarting and using that partition to boot, prohibited symbol is still there

  • Citrix Secure Gateway not redirecting to login URL

    - by Dave
    We have an older setup for XenApp - users log in through Citrix Secure Gateway running on a windows box. (We hope to start using a NetScaler soon.) Earlier today, connections to https://citrix.company.com/ starting throwing up a 503 error page, instead of redirecting to https://citrix.company.com/Citrix/XenApp/ If you go directly to the /Citrix/Xenapp/ URL, the user is properly directed to the login page, and can launch apps. We've restarted the service, and rebooted the server. We haven't yet tried uninstalling and reinstalling the software. Before we do this, I'm looking for ideas as to how we can get the redirect working again without a fairly major outage window. To make things more interesting, many of our users have Citrix Receiver installed, also pointed at https://citrix.company.com/. Receiver makes itself the default launcher for ICA files, and gives a connection error when it tries to load apps - probably because of the same non-functional rediect?

  • Doubts about Cloud Infrastructure

    - by Pravin
    Maybe a little more of the same questions that others have asked but wanted to clarify my doubt, for some years run my hosting company (reseller of esds) and I've done well so far, but I am determined to bring quality and server technology to offer another level. So far I have understood that there is a difference between cloud and cluster servers because the cluster function as load balancers that distribute in different servers roles and use the servers less overloaded in the cloud is the union of multiple servers and then the same is vitualized unlike the cluster that is allowed to use the resources of the CPU and RAM servers in the virtualized environment. My approach is to use 3 dedicated servers to create a cloud server, My doubts: Does this type of cloud servers are only reserved for big companies? (Either because the union of the servers is done by hardware or software with high price) What characteristics should these servers meet? Possibly through software which should be used? Available? Thanks for your time, Cheers!

  • Keyboard input system handling

    - by The Communist Duck
    Note: I have to poll, rather than do callbacks because of API limitations (SFML). I also apologize for the lack of a 'decent' title. I think I have two questions here; how to register the input I'm receiving, and what to do with it. Handling Input I'm talking about after the fact you've registered that the 'A' key has been pressed, for example, and how to do it from there. I've seen an array of the whole keyboard, something like: bool keyboard[256]; //And each input loop check the state of every key on the keyboard But this seems inefficient. Not only are you coupling the key 'A' to 'player moving left', for example, but it checks every key, 30-60 times a second. I then tried another system which just looked for keys it wanted. std::map< unsigned char, Key keyMap; //Key stores the keycode, and whether it's been pressed. Then, I declare a load of const unsigned char called 'Quit' or 'PlayerLeft'. input-BindKey(Keys::PlayerLeft, KeyCode::A); //so now you can check if PlayerLeft, rather than if A. However, the problem with this is I cannot now type a name, for example, without having to bind every single key. Then, I have the second problem, which I cannot really think of a good solution for: Sending Input I now know that the A key has been pressed or that playerLeft is true. But how do I go from here? I thought about just checking if(input-IsKeyDown(Key::PlayerLeft) { player.MoveLeft(); } This couples the input greatly to the entities, and I find it rather messy. I'd prefer the player to handle its own movement when it gets updated. I thought some kind of event system could work, but I do not know how to go with it. (I heard signals and slots was good for this kind of work, but it's apparently very slow and I cannot see how it'd fit). Thanks.

  • What kind of DNS and IIS configuration is needed to allow multiple domains to point to a multi-tenant web application?

    - by holiveira
    I'm developping a multi-tenant web application in ASP.NET MVC and it will provide my users the ability to have a custom subdomain pointing to their account page (like user.myapp.com). I already have it working by using a wildcard DNS entry and a code to query the database to load the user data based on the domain. I'm planning to offer the possibility of using custom domains, allowing the users to buy their own domains and use it instead of the subdomains that will be provided by default. I currently use DNSMadeEasy to host the DNS for the application main domain. I just don't know what kind of settings I must make to allow this feature to work, since the users will have domains hosted in several companies. Will I have to create my own nameservers and provide it to my users? What other things I must consider to implement it efficiently?

  • Why isn't sox able to convert to mp3?

    - by marue
    I installed Sox, i installed lame-398, but sox is not able to convert any file to mp3. It fails with the messages: ./../sox FAIL util: Unable to load LAME encoder library (libmp3lame). ./../sox FAIL formats: can't open output file `funktech.mp3': How can i check if lame has been installed correct? How can i get sox to find the mp3Library? edit: I did not install sox at all, it works without installing directly from the commandline. Lame was installed by following the instructions on their site: ./configure make make install which results in the following files being found in /usr/local/lib/ : libmp3lame.dylib, libmp3lame.la, libmp3lame.a Maybe symlinking libmp3lame.la, which is marked as executable, to /usr/bin would help?

  • Unable to Install VirtualBox Due to Missing Kernel Module

    - by SoftTimur
    I am trying to install VirtualBox on my Ubuntu. I first tried to sudo apt-get install virtualbox-ose in a terminal, but after the configuration step, it fails with an error: No suitable module for running kernel found When proceeding with starting virtualbox, I get this error: WARNING: The character device /dev/vboxdrv does not exist. Please install the virtualbox-ose-dkms package and the appropriate headers, most likely linux-headers-generic. You will not be able to start VMs until this problem is fixed. So I tried the package from http://www.virtualbox.org/, but starting VirtualBox fails with: WARNING: The vboxdrv kernel module is not loaded. Either there is no module available for the current kernel (2.6.38-8-generic-pae) or it failed to load. Please recompile the kernel module and install it by sudo /etc/init.d/vboxdrv setup You will not be able to start VMs until this problem is fixed. So I ran sudo /etc/init.d/vboxdrv setup, but it fails too: * Stopping VirtualBox kernel modules [ OK ] * Uninstalling old VirtualBox DKMS kernel modules [ OK ] * Trying to register the VirtualBox kernel modules using DKMS Error! Your kernel headers for kernel 2.6.38-8-generic-pae cannot be found at /lib/modules/2.6.38-8-generic-pae/build or /lib/modules/2.6.38-8-generic-pae/source. * Failed, trying without DKMS * Recompiling VirtualBox kernel modules * Look at /var/log/vbox-install.log to find out what went wrong The contents of /var/log/vbox-install.log. As I am stuck, I also tried to install kernel-devel with yum, still fruitless: root@ubuntu# yum install kernel-devel Setting up Install Process No package kernel-devel available. Nothing to do Now I've no idea how to correct this. Any ideas?

  • iStack for iPad

    - by Jonathan
    The below image is the current, and hopefully final, look of the front screen, the app will remember which stack site you have chosen so the user will only see this screen the first time, but they can always go back and change it. The red bar is only there when a new site is added (the StackOverflow is just a test as no site has been added since I implemented this) and can be gotten rid of by tapping the X on the right side (which isn't in the screenshot). Each column now has an edit button where the sites can be rearranged and moved from favourites to non favourites and this is persistent between app launches, moving a site in one column moves it in all of them. I've removed site icons in order to put them in properly so they load lazily and theres no UI freezing. Printing Functionality all implemented and working, thanks to systempuntoout's stackprinter.com works with AirPrint, which means this app will be iOS 4.2 minimum. Current features: 3 columns Email link to question, open in safari and copy link actions History for both questions and sites visited In app notification (red bar at the top) when a new site makes it into beta. StackPrinter in the app, without needing safari, and AirPrint functionality. Facebook Intergration Planned: Local Favourites Watching (a list of questions your watching, like short term favourites, with eventually push notifications) Web service to access local favourites and watches on non-iPad devices. Twitter integration. Safari bookmarklet to open question in iStack from safari In app notification for when site progresses from beta to normal. In app notification history

  • Average SPA weight [on hold]

    - by Emmanuel Istace
    First, sorry my noobs questions, but I'm mainly Windows Developer and not Web Developer :) I'm developing a single page application with a lot of css & javascript. For now the page is 1.3Mo composed by 5 section. Here are the rounded stats : Document : 10kb Style : 60kb Images : 450 kb (already compressed, include a big gallery thumbnails) Javascript : 700kb - 600kb of "framework" (jquery, jquery-ui, boostrap, modernizer, waypoint, ...) and 100kb of custom js. Fonts : 125kb And the site is not finished yet. (Will include gmap api, and some others...) My questions are : Do you have any statistics about the average weight of an SPA ? As this is the whole website, do you think it's acceptable ? Is lazy load (for images) a solution ? What will be impact for SEO ? Is the "200kb rule" of google still relevant ? Do you know great tools to detect which javascript code is not used during the the exection of a page and then the availability to optimize these 700kb of framework js stuffs ? Can a caching strategy be an answer ? Thank you in advance for you help ! Best regards

  • Ubuntu server very slow out of the blue sky (Rails, passenger, nginx)

    - by snitko
    I run Ubuntu server 8.04 on Linode with multiple Rails apps under Passenger + nginx. Today I've noticed it takes quite a lot of time to load a page (5-10 secs). And it's not only websites, ssh seems to be affected too. Having no clue why this may be happening, I started to check different things. I checked how the log files are rotated, I checked if there's enough free disk space and memory. I also checked IO rate, here's the output: $ iostat avg-cpu: %user %nice %system %iowait %steal %idle 0.17 0.00 0.02 0.57 0.16 99.07 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn xvda 2.25 39.50 16.08 147042 59856 xvdb 0.00 0.05 0.00 192 0 xvdc 2.20 25.93 24.93 96530 92808 xvdd 0.01 0.12 0.00 434 16 xvde 0.04 0.23 0.35 858 1304 xvdf 0.37 0.31 4.12 1162 15352 Rebooting didn't help either.

  • Lies, damned lies, and statistics Part 2

    - by Maria Colgan
    There was huge interest in our OOW session last year on Managing Optimizer Statistics. It seems statistics and the maintenance of them continues to baffle people. In order to help dispel the mysteries surround statistics management we have created a two part white paper series on Optimizer statistics.  Part one of this series was released in November last years and describes in detail, with worked examples, the different concepts of Optimizer statistics. Today we have published part two of the series, which focuses on the best practices for gathering statistics, and examines specific use cases including, the fears that surround histograms and statistics management of volatile tables like Global Temporary Tables. Here is a quick look at the Introduction and the start of the paper. You can find the full paper here. Happy Reading! Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman","serif";} Introduction The Oracle Optimizer examines all of the possible plans for a SQL statement and picks the one with the lowest cost, where cost represents the estimated resource usage for a given plan. In order for the Optimizer to accurately determine the cost for an execution plan it must have information about all of the objects (table and indexes) accessed in the SQL statement as well as information about the system on which the SQL statement will be run. This necessary information is commonly referred to as Optimizer statistics. Understanding and managing Optimizer statistics is key to optimal SQL execution. Knowing when and how to gather statistics in a timely manner is critical to maintaining acceptable performance. This whitepaper is the second of a two part series on Optimizer statistics. The first part of this series, Understanding Optimizer Statistics, focuses on the concepts of statistics and will be referenced several times in this paper as a source of additional information. This paper will discuss in detail, when and how to gather statistics for the most common scenarios seen in an Oracle Database. The topics are · How to gather statistics · When to gather statistics · Improving the efficiency of gathering statistics · When not to gather statistics · Gathering other types of statistics How to gather statistics The preferred method for gathering statistics in Oracle is to use the supplied automatic statistics-gathering job. Automatic statistics gathering job The job collects statistics for all database objects, which are missing statistics or have stale statistics by running an Oracle AutoTask task during a predefined maintenance window. Oracle internally prioritizes the database objects that require statistics, so that those objects, which most need updated statistics, are processed first. The automatic statistics-gathering job uses the DBMS_STATS.GATHER_DATABASE_STATS_JOB_PROC procedure, which uses the same default parameter values as the other DBMS_STATS.GATHER_*_STATS procedures. The defaults are sufficient in most cases. However, it is occasionally necessary to change the default value of one of the statistics gathering parameters, which can be accomplished by using the DBMS_STATS.SET_*_PREF procedures. Parameter values should be changed at the smallest scope possible, ideally on a per-object bases. You can find the full paper here. Happy Reading! +Maria Colgan

  • Apache Passenger can't find gem

    - by purpletonic
    I'm running Ubuntu 10.04 and I've transferred over some sites built in Sinatra. I've set up Phusion passenger, but when I visit the sites I'm getting a Passenger LoadError claiming that passenger has 'no such file to load -- sinatra' yet when I run gem list or sudo gem list, I clearly see sinatra listed. Why can't passenger find this gem? My sudo gem env output looks like this RubyGems Environment: - RUBYGEMS VERSION: 1.3.5 - RUBY VERSION: 1.8.7 (2009-12-24 patchlevel 248) [x86_64-linux] - INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.8 - RUBY EXECUTABLE: /usr/local/bin/ruby - EXECUTABLE DIRECTORY: /usr/local/bin - RUBYGEMS PLATFORMS: - ruby - x86_64-linux - GEM PATHS: - /usr/local/lib/ruby/gems/1.8 - /root/.gem/ruby/1.8 - GEM CONFIGURATION: - :update_sources = true - :verbose = true - :benchmark = false - :backtrace = false - :bulk_threshold = 1000 - REMOTE SOURCES: - http://gems.rubyforge.org/ running 'sudo ruby -v' I see the following: ruby 1.8.7 (2009-12-24 patchlevel 248) [x86_64-linux], MBARI 0x6770, Ruby Enterprise Edition 2010.01 Is that correct, or should the two ruby versions match up correctly, displaying REE in both? Thanks in advance!

  • How to Boot a VMware Virtual Machine from a USB Drive

    - by Usman
    Do you have an OS installed on your USB thumb drive? Booting from it in a VM is now possible, you’ll just have to use a simple trick to get it to work. Last week we showed you how to put Ubuntu on a USB drive in a separate partition, and we also discussed working with VMware Player (our favourite VM Client). But have you ever tried booting from a USB drive in VMWare? It doesn’t allow doing so, but we will force it to boot from a USB, with a bit of old geekery. If you remember, we have showed you how to boot from a USB drive even if your old PC doesn’t allow booting from one. That’s right, using Plop Boot Manager. All we need to do is to load the Plop ISO in VMware, attach and enable the USB drive in VMware, and finally select the USB option in Plop Boot Manager to boot from the USB. So, visit the Plop boot manager download site. HTG Explains: When Do You Need to Update Your Drivers? How to Make the Kindle Fire Silk Browser *Actually* Fast!

  • Dynamic Forms: Pattern or AntiPattern?

    - by Segfault
    I'm sure you've seen it. The database has a bunch of tables called Forms, Controls,FormsControls, ControlSets, Actions and the program that queries these tables has a dynamically generated user interface. It will read all the forms, load a home page that has links to them all, or embed them in some tabbed or paged home page, and for each of those forms it will read the various text boxes, check boxes, radio buttons, submit buttons, combo boxes, labels and whatnot from the controls and form-to-control join tables, lay those elements out according to the database and link all the controls to logic according to other rules in the database. To me, this is an anti-pattern. It actually make the application more difficult to maintain because the design of it is now spread out into multiple different systems. Also, the database is not source controlled. Sure, it may make one or two changes go more quickly, after you've analyzed the program anyway to understand how to change the data and as long as you don't stray from the sort of changes that were anticipated and accounted for, but that's often just not sustainable. What say you?
