  • What is the name for landing pages that are one long page?

    - by blunders
    Really don't see them much anymore, but here's an example of what I mean: From comments: These are "high pressure" sales pages, design to overload the user with information, sell them on the belief that what they're buying is what they need, normally have a lot of testimonials, highlighted text, etc. The pages I'm talking about are not user friendly, they're aggressive sales pitches designed to target users wanting to belief the webpage they just landed on will solve there problems for an "affordable" price. Here's an example: www_landingpagecashmachine_com (remove the underscores, since I'm attempting to avoid linking to a site like that...) Bonus points: if you're able to tell me the name of the guy/company that popularized these types of pages; recall hearing about his company years ago, after he died in a crash while racing on a track with his Ferrari club on the west coast of the US. (Update: Appears Corey Rudl was the guy's name, and his company was called "The Internet Marketing Center." Even with that info, I've still been unable to find the name for these type of pages.)

  • Why does qt-creator need to connect to google-analytics?

    - by Nanda
    I just installed qt-creator to work on non-qt C++ projects. The installed version is 2.5.0 (Based on Qt 4.8.2 32-bit) If I click on any of these pages: I get this error: I realized that /etc/hosts file has the following entry: 127.0.0.1 www.google-analytics.com I don't want to remove the entry from the hosts file because it's always been there along with thousands of other similar adservices/porn/malware addresses. I do not intend to say that qt-creator is looking to create problems in my computer, but I am genuinely interested to know why qt-creator needs to connect to google-analytics? Can this be disabled and qt-creator can still be functional?

  • Calling all developers building ASP.NET applications

    - by Laila Lotfi
    We know that developers building desktop apps have to contend with memory management issues, and we’d like to learn more about the memory challenges ASP.NET developers are facing. To be more specific, we’re carrying out some exploratory research leading into the next phase of development on ANTS Memory Profiler, and our development team would love to speak to developers building ASP.NET applications. You don’t need to have ever used ANTS profiler – this will be a more general conversation about: - your current site architecture, and how you manage the memory requirements of your applications on your back-end servers and web services. - how you currently diagnose memory leaks and where you do this (production server, or during testing phase, or if you normally manage to get them all during the local development). - what specific memory problems you’ve experienced – if any. Of course, we’ll compensate you for your time with a $50 Amazon voucher (or equivalent in other currencies), and our development team’s undying gratitude. If you’d like to participate, please just drop me a line on [email protected].

  • Unable to mount samsung galaxy S3 via USB

    - by dez93_2000
    Connecting as either MTP or PTP: neither allows one to see pictures saved as default by phone camera to DCIM folder on external SD card. Similar problems with previous models (e.g. S2) were solvable by 'usb utilities' in wireless & networking settings, but this is no longer present. Other suggestions have mentioned uninstalling various libraries... but i don't wanna just start cutting stuff without knowing it'll help. Any thoughts? Seems like a pretty epic fail from google & samsung. There's not even a linux section on the relevant google site... despite android's usb driver being part of the linux kernel which powers android. Boo!

  • Compilable modern alternatives to C/C++

    - by Jeremy French
    I am considering writing a new software product. Performance will be critical, so I am wary of using an interpreted or language or one that uses a emulation layer (read java). Which leads me to thinking of using C (or C++) however these are both rather long in the tooth. I haven't used either for a long time. I figure in the last 20 years someone should have created something which is reasonably popular and is nice to code in and is complied. What more modern alternatives are there to C for writing high performance code compiled code? edit in response to comments If C++ is a different beast than it was 15 years ago, I would consider it, I guess I had an assumption that it had some inherent problems. Parallelisation would be important, but probably not across multiple machines.

  • ATI graphics card, with gnome shell on Ubuntu 11.10, screen flickers

    - by bioShark
    After installing gnome shell, without any problem, after log in the fonts are missing and it looks like crap...nothing is readable. Don't want to make it a double post, because my issue is similar to the one from this question but for me the problems have not been solved properly. After running the commands from that post, and installing the latest AMD 11.10 driver, the Gnome shell display issues have been solved. But each time I move the mouse in the upper left corner, to bring up the applications...my entire screen flickers. Without the applications been displayed, everything looks fine. Hardware: ATI HD4870, Intel Q6600.

  • is there a bug with restart in edubuntu 12.04

    - by Ket
    After a clean install of edubuntu 12.04 on an Acer AO531-h netbook, restart doesn't work. The process starts normally but just before it shuts down the netbook freezes and I have to force shut down. The command "sudo reboot" has the same problem. I have no issues with shut down, only with restart. I'm absolute beginner. Netbook specs: Acer, intel atom CPU N270 @1.60GHz, 1.05 GHz 0.98GB RAM Dual booting with windows xp. No problems with windows.

  • Keyboard Mouse Problem

    - by Zachary K
    I just installed Ubuntu on my laptop (Core 2 Duo Sony Vaio) and am having a problem with the external keyboard and mouse. When I first logged in the left mouse button does not work, this can be solved by unplugging the external keyboard/mouse's USB connector and then plugging it back in again. But Then randomly other problems happen. (Shift gets stuck, keys don't work etc) The keyboard and mouse are a generic brand wireless (A4 Tech) that I got for cheap. Both work OK under windows so this is a major pain.

  • Pair programming and unit testing

    - by TheSilverBullet
    My team follows the Scrum development cycle. We have received feedback that our unit testing coverage is not very good. A team member is suggesting the addition of an external testing team to assist the core team, but I feel this will backfire in a bad way. I am thinking of suggesting pair programming approach. I have a feeling that this should help the code be more "test-worthy" and soon the team can move to test driven development! What are the potential problems that might arise out of pair programming??

  • I have two versions of glib on my system, and I don't know how to remove the old one

    - by Dameentsia
    While trying to compile a program (pygobject), running ./configure I am told that I don't have glib. So, I download the tarball and compile and install, no problems. now when I try to ./configure the package again, I get the following error: checking for GLIB - version >= 2.24.0... *** 'pkg-config --modversion glib-2.0' returned 2.34.2, but GLIB (2.34.0) *** was found!

    - by Bragboy

Here are the problems that happen Desktop background goes away As you can see on the left hand side of the desktop, the right and top portions are black The usual buttons - power button, mail, volumne etc., on the top panel do not work as expected Plus it suddenly crashses at times. And a lot of n other issues associated with this. Is there any patch/release that has happened for these bugs or should I report it anywhere? Help needed.

  • Trim on encrypted SSD--Urandom first?

    - by cb474
    My understanding (I'm not sure I'm getting this all right) is that if one uses Trim on an encrypted SSD, it defeats some of the security benefits, because the drive will write zeros to empty space (as files are deleted). See: http://www.askubuntu.com/questions/115823/trim-on-an-encrypted-ssd And: http://asalor.blogspot.com/2011/08/trim-dm-crypt-problems.html My question is: From the perspective of the performance of the SSD and the functioning of Trim, would it therefore be better to simply zero out the SSD, before setting up an encrypted system, rather than writing random data to the drive, with urandom, as one usually does? Would this basically leave one with the same level of security anyway? And more importantly, would it better enable the Trim functionality to work as intended, with the encrypted SSD?

I would like to be able to see all of those systems, my code, lots of log files and documentation without the need to swap windows/screens. To just better see what im doing.

  • Ubuntu 12.10 desktop/interface not showing on VirtualBox VM after login screen

    - by Jake
    I'm having some trouble with getting my Ubuntu to work on a VirtualBox VM. I made a clean installation of Ubuntu 12.10 on a VM without any errors. I arrive at the login screen, as soon as I press enter it does it's little loading thingy and then screen goes black, then this is all I get: http://i.imgur.com/zULUI.jpg I can access the terminal and pretty much all the other features through it, but I would like to have the GUI properly working. I've been looking around the web and looking at various fixes to similar problems, but can't seem to get it to work. I'm thinking this problem might have to do with the graphics? I'm running Windows 8 Pro as host, if that helps, might be some compatibility issues with VirtualBox in W8... Thanks in advance!

  • Write own messaging system vs. utilize existing ones

    - by A.Rashad
    We are trying to have our own startup, with a middleware application to glue small applications with enterprise legacy systems. for such middle-ware to function properly, we will need some sort of messaging system to make different components talk to each other in a reliable way. the alternatives are: use an existing messaging system, such as 0MQ, jBOSS, WebSphere MQ, etc. build our own messaging system the way we see the problem I am more biased towards the later option for the following reasons: to have more control over our final product to avoid any licensing problems later on to learn about messaging while writing the code to invent something new, that might cost us lots of $$$ if reused an existing system What would you do if in my shoes?

  • How to find corrupted files?

    - by rafalcieslak
    Some files on my hard drive are corrupted (no worries, nothing system-related, just a junk of data files, mp3 etc.). I found that out when I tried to burn them all to a DVD, the burning application show a message that it cannot read the files as they are corrupted. [This is probably a drive issue, it had happened me once or twice already]. I don't care about recovering them, but I have to determine which ones are corrupted. I cannot check by manually opening them all, as there are thousands of them. Is there any tricky way to check all the files and list the ones that may cause problems when tried to open?

  • CW/CCW Rotation of a Vector

    - by user23132
    Considering that I have a vector A, and after an arbitrary rotation I get vector B. I want to use this rotation operation in others vectors as well, but I'm having problems in doing that. My idea do that is to calculate the perpendicular vector C of the plane AB (by calculating AxB). This vector C is the axis that I'll need to rotate. To discover the angle I used the dot product between A and B, the acos of the dot product will return the lowest angle between A and B, the angle ang. The rotation I need to do is then: -rotate *ang*º around the C axis. The problem is that I dont know if this rotation is a CW or CCW rotation, since the cos of the dot product does not give me information of the sign of the angle. There's a tip discover that in 2D ( A.x * B.y - A.y * B.x) that you can use to discover if the vector A is at left/right of vector B. But I dont know how to do this in 3D space. Can anyone help me?

  • Why dosn't Ubunto like my HP Pavilion G7?

    - by user109379
    I installed Ubunto onto my HP Pavillion G7 1330dx without much problem, but it took 3 or more tries to get it to boot up after. Then , I started over and installed Mint, no problems installing or booting up. BUT, I decided I I liked Ubunto better so I wiped my hard drive and installed Ubunto ( this time the 32 bit) ,It runs great once i finally get it to boot, it takes 3 or more tries again. Whats the deal? I really like it but really don't know what I'm doing. I've been a Windows guy until a couple days ago.

  • Best practice Java - String array constant and indexing it

    - by Pramod
    For string constants its usual to use a class with final String values. But whats the best practice for storing string array. I want to store different categories in a constant array and everytime a category has been selected, I want to know which category it belongs to and process based on that. Addition : To make it more clear, I have a categories A,B,C,D,E which is a constant array. Whenever a user clicks one of the items(button will have those texts) I should know which item was clicked and do processing on that. I can define an enum(say cat) and everytime do if clickedItem == cat.A .... else if clickedItem = cat.B .... else if .... or even register listeners for each item seperately. But I wanted to know the best practice for doing handling these kind of problems.

  • Is Ubuntu running well on an usb hdd? Need suggestions

    - by Klaus
    Dear Linux and Ubuntu pros, I have here a company notebook, and because the hdd is full encrypted I cannot install an extra partition for another system that I would like to use in my free time. And I really need another system, because this crap windows here with that much of antivirus, antispyware, anti-whatever on it is sooo slow and anoying. What can I do? I could use an external usb hdd with another system. Because I would like to handle big files and so on, I dont want to use an sub stick. An usb 2.5hdd + ubuntu is what I think the best option. Here are my question: Do I have to note something? Is Ubuntu running well on an external hdd? Do I have big performance problems (because of the usb hdd)? Should I buy a very fast hdd for much money or is it not that important? Any suggestions? Thank you :)

  • have a missing file, and cant run ubuntu upon start up, and hasnt the flash drive i used didnt work either, any help?

    - by trent
    when I first downloaded Ubuntu to install it, it downloaded quick and caused no problems to my laptop. but then when it came time to install it as one of my operating systems, it wouldn't run because it said a file was missing or damaged. so then I uninstalled it and re-installed it but I still had that same problem. so I tried a flash-drive version but that didn't work either because it wouldn't boot from that, nor would it detect my flash drive, (in this case, an old 4 GB mp3 player). any help or tips and ideas would be great, I just need a decent operating system because windows is getting to be terrible at the moment, just note I wanna run Ubuntu along side windows 8.1

  • Why is the file /var/crash/_usr_lib_empathy_empathy-chat.1000.upload empty?

    - by user43816
    I just experienced an unusual crash: I tried to click on a name entry in the contact list of Empathy. A crash happened. Usually I am asked then if I'd like to report the error to Launchpad, and Launchpad opens. This time the error message was: "Excuse me. Ubuntu 12.04 noticed an internal error. If you notice further problems try to restart your computer. Send an error report to Launchpad to help removing this problem?" This time Launchpad did not open automatically. A new window opened and I could read the relevant error report. Later I found the error report in the file /var/crash/_usr_lib_empathy_empathy-chat.1000.crash. Why went the course of action this time differently from other crashes? Why is the file /var/crash/_usr_lib_empathy_empathy-chat.1000.upload empty?

  • Boot-up hangs unless I manually select the kernel in the bootloader

    - by The Photon
    In my stock Ubuntu install (forgot which critter its named for, about one year old), I am able to boot up normally only if I manually select the kernel in the bootloader (Grub). If I step away and it boots from the default, the system will hang with the word "Ubuntu" on a graphics screen and a few white/red blinking dots beneath it. umb@digdug:~$ uname -a Linux digdug 2.6.32-42-generic #95-Ubuntu SMP Wed Jul 25 15:57:54 UTC 2012 i686 GNU/Linux Synaptics says I have 'grub-pc' version 1.98-1ubuntu-13 installed. My grub.cfg does have default="0" which I would expect to make the default be the first kernel shown in the selection screen. The system is a laptop with an i7 processor, and I have had trouble with some kernels not being able to boot at all in the past, and power management is not working perfectly, but I have not had problems booting the latest kernel (2.6.32-42) if I select it manually in Grub. Any idea what is going on here and how can I fix it so that I can re-boot unattended?

  • Recommended book on Actors concurrency model (patterns, pitfalls, etc.)?

    - by Larry OBrien
    The Actors concurrency model is clearly gaining favor. Is there a good book that presents the patterns and pitfalls of the model? I am thinking about something that would discuss, for instance, the problems of consistency and correctness in the context of hundreds or thousands of independent Actors. It would be okay if it were associated with a specific language (erlang, I would imagine, since that seems universally regarded as the proven implementation of Actors), but I am hoping for something more than an introductory chapter or two. (FWIW, I'm actually most interested in Actors as they are implemented in Scala.)
