  • Why do programs take more than 2 seconds to load on my Ubuntu 12.04?

    - by Gaige
    Here's a description of my build (simple) Processor: AMD Phenom II x6 1090t Ram: 16gb 1333 mhz Board: TA990FXE Video Card : HD 6870 HDD Ubuntu is installed on: 320gb caviar blue 7200rpm That should be sufficient enough to diagnose this. Yes I did install the AMD video drivers recommended by Ubuntu. Programs take 2+ seconds to load, and I really don't tolerate that...Windows 7 loads programs as fast as my hdd allows Unless this is how Ubuntu is meant to work...then I'll just go back to Debian command-line.

  • Improving terminal server performance for a specfic app

    - by Matt
    We have a windows 2003 terminal server running 2X application load balancign that is hosting a client's application that is accessed by around 50 users. Each user has there own database. The database is a file based database. The application is developed under Delphi so I think the database may be BDE based. As you can imagine, there is probably quite a lot of disk i/o. Here are some of the perfmon settings. Logged in users (average) 20 - 25 CPU Utilization (average) 80 - 100% Disk Queue Length (average) 1.6 % Disk time (average) 111 Page faults/sec (average) 1400 The application takes on average about a minute to load up. As usual, the budget is tight. Is there basic windows performance tuning tips that people can recommend to improve things before we fork out on more RAM etc. Server is a 2.8GHz Xeon with 3GB of RAM.

  • What kinds of protections against viruses does Linux provide out of the box for the average user?

    - by ChocoDeveloper
    I know others have asked this, but I have other questions related to this. In particular, I'm concerned about the damage that the virus can do the user itself (his files), not the OS in general nor other users of the same machine. This question came to my mind because of that ransomware virus that is encrypting machines all over the world, and then asking the user to send a payment in Bitcoin if he wants to recover his files. I have already received and opened the email that is supposed to contain the virus, so I guess I didn't do that bad because nothing happened. But would I have survived if I opened the attachment and it was aimed at Linux users? I guess not. One of the advantages is that files are not executable by default right after downloading them. Is that just a bad default in Windows and could be fixed with a proper configuration? As a Linux user, I thought my machine was pretty secure by default, and I was even told that I shouldn't bother installing an antivirus. But I have read some people saying that the most important (or only?) difference is that Linux is just less popular, so almost no one writes viruses for it. Is that right? What else can I do to be safe from this kind of ransomware virus? Not automatically executing random files from unknown sources seems to be more than enough, but is it? I can't think of many other things a user can do to protect his own files (not the OS, not other users), because he has full permissions on them.

  • What is a realistic average time difference between servers in the same LAN?

    - by monster
    Until recently, we had at work a small cluster of about 20 small Windows servers (which have now all been virtualized). They were all configured to synchronize with the local time server. It was on an 1Gb sub-network in our own DC. I never got them to be less than about 100ms away from each other, which I consider to be an incredibly big difference. Is that a normal value? What is a realistic expectation of time difference between machines running on a 1Gb network, and all connected to the same time server, and updating frequently, say every 5 minutes? I would like to know this as setting timeouts and other parameters in a distributed application requires to take that difference into consideration.

  • How to select from tableA sum of grouped numbers from tableB above their sums average in Oracle?

    - by Nazgulled
    I have data like this: tableA.ID --------- 1 2 3 tableB.ID tableB.NUM -------------------- 1 10 1 15 2 18 3 12 2 15 3 13 1 12 I need to select tableA IDs where the sum of their NUMs in tableB is above the average of all tableA IDs sums. In other words: SUM ID=1 -> 10+15+12 = 37 SUM ID=2 -> 18+12+15 = 45 SUM ID=3 -> 12+13 = 25 AVG ALL IDs -> (37+45+25)/3 = 35 The SELECT must only show ID 1 and 2 because 37 35, 45 35 but 25 < 35. This is my current query which is working fine: SELECT tableA.ID FROM tableA, tableB WHERE tableA.ID = tableB.ID HAVING SUM(tableB.NUM) > ( SELECT AVG(MY_SUM) FROM ( SELECT SUM(tableB.NUM) MY_SUM FROM tableA, tableB WHERE tableA.ID = tableB.ID GROUP BY tableA.ID ) ) GROUP BY tableA.ID But I have a feeling there might be a better way without all those nested SELECTs. Perhaps 2, but 3 feels like too much. I'm probably wrong though. For instance, why can't I do something simple like this: SELECT tableA.ID FROM tableA, tableB WHERE tableA.ID = tableB.ID HAVING SUM(tableB.NUM) > AVG(SUM(tableB.NUM)) GROUP BY tableA.ID Or this: SELECT tableA.ID, SUM(tableB.NUM) MY_SUM FROM tableA, tableB WHERE tableA.ID = tableB.ID HAVING MY_SUM > AVG(MY_SUM) GROUP BY tableA.ID

  • How do I host multiple SSL websites on a single EC2 instance using Amazon Elastic Load Balancers?

    - by Developr
    If I have 3 separate websites which all require SSL (separate certificates) that I want to host on the same EC2 instance(s) across multiple availability zones so that we have the ability to scale and be highly available, how do I achieve this using ELBs in my Amazon VPC? Each site requires a separate IP address, so I have added multiple private IPs to the EC2 instance, but I am unsure how to bind the ELB to a certain IP on the instance. I was also able to setup multiple ELB pointing to the same instance, but again, I am not seeing any way to bind each ELB to a separate IP on the instance. If this is not possible, what is the best option? Run each site on a separate EC2 instance / ELB combo (expensive and harder to maintain) Give each site a separate public IP and use Route 53 to do the load balancing (seems like a hack) Use a different load balancer option such as HAProxy that should be able to work like a normal load balancer appliance. Please help!

  • How do I make a firefox extension execute script on page open/load? [migrated]

    - by Will Mc
    Thanks in advance! I am creating my first extension (A firefox extension). See below for full description of final product. I need help starting off. I have looked and studied the HelloWorld.xpi example found on Mozilla's site so I am happy to edit that to learn. In the example, when you click a menu item it runs script to display an alert message. My question is, how would I edit this extension to run the script on page load? I am guessing I need to insert some code in the browserOverlay as it loads on page load so, here is the browserOverlay.xpi from the example I am editing to learn: <?xml version="1.0"?> <?xml-stylesheet type="text/css" href="chrome://global/skin/" ?> <?xml-stylesheet type="text/css" href="chrome://xulschoolhello/skin/browserOverlay.css" ?> <!DOCTYPE overlay SYSTEM "chrome://xulschoolhello/locale/browserOverlay.dtd"> <overlay id="xulschoolhello-browser-overlay" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script type="application/x-javascript" src="chrome://xulschoolhello/content/browserOverlay.js" /> <stringbundleset id="stringbundleset"> <stringbundle id="xulschoolhello-string-bundle" src="chrome://xulschoolhello/locale/browserOverlay.properties" /> </stringbundleset> <menubar id="main-menubar"> <menu id="xulschoolhello-hello-menu" label="&xulschoolhello.hello.label;" accesskey="&xulschoolhello.helloMenu.accesskey;" insertafter="helpMenu"> <menupopup> <menuitem id="xulschoolhello-hello-menu-item" label="&xulschoolhello.hello.label;" accesskey="&xulschoolhello.helloItem.accesskey;" oncommand="XULSchoolChrome.BrowserOverlay.sayHello(event);" /> </menupopup> </menu> </menubar> <vbox id="appmenuSecondaryPane"> <menu id="xulschoolhello-hello-menu-2" label="&xulschoolhello.hello.label;" accesskey="&xulschoolhello.helloMenu.accesskey;" insertafter="appmenu_addons"> <menupopup> <menuitem id="xulschoolhello-hello-menu-item-2" label="&xulschoolhello.hello.label;" accesskey="&xulschoolhello.helloItem.accesskey;" oncommand="XULSchoolChrome.BrowserOverlay.sayHello(event);" /> </menupopup> </menu> </vbox> </overlay> I hope you can help me. I need to know what code I should use and where I should put it... Here is the gist of my overall extension - I am creating a click to call extension. This extension will search any new page for a phone number whether just refreshed, new page, new tab etc... Each phone number when clicked will open a new tab and direct user to a custom URL. Thanks again!

  • Does Google include the time to load images, for a single page, as part of the page speed?

    - by Pure.Krome
    we all know that Google's affects your page rank with the load time of a page. How? That's part of the secret sauce. But we know that page speed is a serious factor. So - what is considered the speed of a page? Is it just the first (and main) html file which the GET receives? Or does it also include loading of images as part of that speed. so for example... GET /index.htm <- takes 0.45 seconds to retrieve (including DNS lookup before). robot parses page.. see's there's a single main image.... GET /img/main.png <- takes 5 seconds to download. is the page speed for that resource, 0.45 seconds OR 5.45 seconds? I understand Javascript is not fired .. but are any of these external resources all downloaded and part of the page speed?

  • How do I prevent useless content load on the page in responsive design?

    - by Ícaro Leandro
    In responsive design, elements are hidden in the page with @media queries and display: none in CSS. Ok. In my design however browsers that have less than 800px in width should avoid loading some content at all. When accessed with on a device with more than 800px of screen, the page loads fully. In mobile devices or even on desktop with less than 800px of width some content is hidden. I want to make the page load faster for low-resolution devices and avoid loading chunks of content that the user will never see. How can I go about this?

Thanks for any advice.

  • Is there a ".d" directory to use to load modules at boot time, opposed to /etc/modules?

    - by gertvdijk
    I am automating some configurations on my systems using Puppet. For a group of machines I want to load a kernel module at boot time. The most elegant way seems to edit /etc/modules and add one on an individual line. However, I would like to use separate files in a ".d" directory structure for easier maintainability. For modprobe and specifying the options for modules, there's /etc/modprobe.d/, but what's the most elegant way for actually loading modules at boot time using a single new file? Basically, I'm looking for the non-existing /etc/modules.d/ directory. Any suggestions?

  • Does connection pooling work fine to execute 60 DB queries to load a page?

    - by willem
    We use Linq2Sql in an ASP.NET application. Unfortunately the eager-loading in Linq2Sql isn't as powerful as in Entity Framework, so a lot of the data has to be lazy loaded as needed. Taking connection pooling into account, is it OK for a web page to execute 60 queries to load a page? Executing a single big query probably won't be much better, as those 60 queries will all those connection pooled connections and not open a new connection each time (which I realize is slow). Any thoughts?

  • after Bios screen appears, the purple screen appears with a red circle and a white line through it, saying cannot load Ubuntu 2D

    - by Felix
    After the Bios screen appears, the purple screen appears and says, "cannot load Ubuntu2D" Log off. Logging off is my only option. I am operating on a Dell Insoirion 11.10 Ubuntu system. I deleted the gnome because I read in the forum it slowed down the computer and I wanted to watch movies. I deleted Unity as well because I read terrible things about it and that it was not necessary for me. I realize my experimention in learning by adding and deleting things were not proper. I was just trying to learn and fix my sound. Please help. Thanks.

  • How do you load in a .bmp file to use it as a height map in C++?

    - by user1324894
    I need to create a terrain that can be used in C++ and opengl and I am told that using a height map is the way to go. I have a .bmp file that is a greyscale image that I would like to use. However, I do not know how to load that greyscale image into the project so that it can be used as a height map or how I can apply a texture to it to create terrain nor how to compute the normals that I'm told will be required. How would I go about achieving what I would like to do?

  • What is the correct way to reset and load new data into GL_ARRAY_BUFFER?

    - by Geto
    I am using an array buffer for colors data. If I want to load different colors for the current mesh in real time what is the correct way to do it. At the moment I am doing: glBindVertexArray(vao); glBindBuffer(GL_ARRAY_BUFFER, colorBuffer); glBufferData(GL_ARRAY_BUFFER, SIZE, colorsData, GL_STATIC_DRAW); glEnableVertexAttribArray(shader->attrib("color")); glVertexAttribPointer(shader->attrib("color"), 3, GL_FLOAT, GL_TRUE, 0, NULL); glBindBuffer(GL_ARRAY_BUFFER, 0); It works, but I am not sure if this is good and efficient way to do it. What happens to the previous data ? Does it write on top of it ? Do I need to call : glDeleteBuffers(1, colorBuffer); glGenBuffers(1, colorBuffer); before transfering the new data into the buffer ?

  • How does having assets saved on a secondary domain(s) reduce the load time of the website?

    - by AAA
    I went for an interview yesterday where I was asked this question: "How does having assets (images/videos) stored on a secondary domain (assets.example.com) reduce the load time of example.com?" To that I answered that by having the code "call" those assets from a secondary website it reduces the traffic that is coming to the main domain and therefore only applying bandwidth to the main domain vs having to also serve bandwidth to request assets. Is that correct? Also, If i am correct, would you say it makes sense to start new websites with this in mind or do you prefer having it done after large traffic rates are achieved?

  • Flash ActiveX: How to Load Movie from memory or resource or stream?

    - by yuku
    I'm embedding a Flash ActiveX control in my C++ app (Flash.ocx, Flash10a.ocx, etc depending on your Flash version). I can load an SWF file by calling LoadMovie(0, filename), but the file needs to physically reside in the disk. How to load the SWF from memory (or resource, or stream)? I'm sure there must be a way, because commercial solutions like f-in-box's feature Load flash movies from memory directly also uses Flash ActiveX control.

  • Facebook Share doesn't pick up title / description meta tags that are changed after page load.

    - by Memo
    Apparently Facebook Share doesn't pick up the title / description meta tags that are changed (via JavaScript) after the page load. It basically use the meta tags that are available upon load. This is a simple example. The link will change the title / description meta tags upon click. You can confirm that using Firebug. Click the f|Share button: Facebook still always shows "A title that is available upon page load." and "A description that is available upon page load." Anybody knows how to fix this?
