• Ubuntu works in try out but not when installed, how to fix?

  - by QVaren

  I've got quite a problem with it, perhaps the problem lies with me but I thought I fixed it, I believe the opposite now... Anyhow, I started off with a 64-Bit Windows 7 platform and I wanted something new then the same boring windows, I heard about Ubuntu before but I didn't see a reason to change it. Now I had found my reason, so what did I do was do the installation via an USB, I went "try out before installation" first and it worked perfectly, however... When I installed it, deleted my Window 7 and tried to reboot with my fresh oh-so-clean new OS, it didn't want to load. At a certain point it said to boot up from a bootable option or something like that. Where it came to was that I couldn't load it up. Now, I wanted to switch back to Windows 7 because it didn't work and now I can't switch back because my harddrive switched modus because of Linux files (From NTFS to 4ex or something, I forgot). I'm currently typing this in the try out version of Ubuntu since I can't switch back to either Windows 7 or to the installed version of Ubuntu. So, my question follows: Can I fix it by keeping Ubuntu? Because I like Ubuntu. Also a side note: I'm a total noob when it comes down to this sort of things.

• After installing Ubuntu my computer boots into GRUB rescue mode after displaying 'no such partition' error message.

  - by VictorVictor5

  I wanted Ubuntu on my Gateway Solo Laptop. It had Win98 on the C:\ and WinXP on the D:\. Before the install, I could not boot from CD, but I could boot from floppy. I installed Ubuntu to run alongside Windows XP as that was one of the options. It didn't detect Win98, but I swear it's on there. Install seemed fine and then it asked me to reboot. When I rebooted, I got the message error: no such partition and the grub rescue> command prompt. I've looked around, but some commands, like sudo, don't work. One command I did get to work was set root=(hd0,0) if that helps. I'm a noob, and it was a pain installing Win98 and XP since this system is so old. I don't want to wipe my drive and start all over! Additional details copied from comments Addendum, I restored my master boot record via my Win98 boot floppy and typing in frisk /mbr. But, I'd still like to get ubuntu - any help? If I restored my master boot record - did I delete Ubuntu?

• Create / build / generate a web form that can be on my server and has modern looks and could be impl

  - by Luay

  I have a small web site and would like to add a 'contact us' form and a 'feedback' form. i would like the forms to satisfy the following: 1- be modern looking (with beautiful css effects) 2- the form fields are validated properly and 'inline'. What I mean is once a user skips a required field or enters an email address incorrectly some kind of tooltip or icon is displayed to ask him to cerrect the error (as opposed to a message box that appears after the user clicks 'submit') 3- once the submit button is clicked the form contents are emailed to me. 4- the whole thing can be setup by a noob like myself. 5- no ads on the form I have been searching for at least 5 days for a solution but I can't seem to find anything the would satisfy the above 5 conditions. I don't mind paying for a solution as long as it is hosted on my site and it is a one off payment and not a monthly payment. So far my search has lead me to the following: 1 wufoo. The good: the generated forms seem to look okay but not the best there is. The bad: the free service is limited to 100 submissions. ads on the form. it is not hosted on my server. Paid service requires monthly payments 2- emailmeform: almost same as above except the generated form looks old. They do have an offer where you pay only $4 to get the form and set it up on your own site but that doesn't solve the fact that the forms look old. 3- formAssembly: same as above with minor variations (the generated form looks better) 4- formchamp, formthis, kontaktr,... And other similar online services: the same problem. either the form generated looks outdated or require monthly payments or they put ads...they don't satisfy my conditions. 5- coffeecup form builder. a desktop software. The problem is the generated forms look too old and use flash. 6- simfatic. Another software. Much better than coffeecup. almost satisfies my conditions but the forms not as good as I like. 7- many, many php scripts or html templates that look so outdated or fail when tested (probably because they are too old). Seriously guys, how hard is this. At least 90%+ of website contain at least a 'contact us' form. Why aren't there better solutions? if there is I can't seem to find them. In terms of looks I want something similar to this: http://web-kreation.com/articles/lightform-free-ajaxphp-contact-form/ It is called lightform. And this is a perfect example of what I mean by 'inline' validation. the only problem: there is no script to handle sending the mail. Even if I find one, I don't know how to modify it for my needs. So could you please help me out. I really can't search anymore. I reached rock bottom with this issue. I need a complete solution. If nothing exists then at least a: 1- form template (html) that looks nice and can easily be modified 2- a validation script that does 'inline' validation like the example above (or similar to it) and can be easily implemented by a noob like me to work with the html form. 3- a php script that will handle sending the email and can be easily implemented (all three working in harmony). I hope there is a complete solution but am I asking for too much? Pretty please...help...

• Log - Server kernel: INFO: task httpd:000000 blocked for more than 120 seconds

  - by valter

  Almost everyday my server is crashing due to hight server load, and even restarting apache or mysql can't solve the problem. I need to reboot the server to solve, or it crash again due to the high load. The log system records something like this when it crashes: Aug 11 18:33:53 server kernel: INFO: task httpd:20008 blocked for more than 120 seconds.

But it looks that the solution is just to update the kernel or disk driver, thinks that I don't know how to do. In this url http://bugs.centos.org/view.php?id=4515 a lot o people report similar problems, except the fact that they are not related to httpd like mine. According to one member, one solution would be to add "elevator=noop " to /etc/grub.conf like in this example: title CentOS (2.6.18-238.12.1.el5xen) root (hd0,0) kernel /vmlinuz-2.6.18-238.12.1.el5xen ro root=/dev/VolGroup00/LogVol00 elevator=noop initrd /initrd-2.6.18-238.12.1.el5xen.img Would this really solve the problem? My disk are working in RAID. Can this cause some problem to my server? Is there any other solution?

• How to parse Json object in ASP classic passed from jQuery

  - by Michael Itzoe

  Using a jQuery dialog, on clicking OK I call $.post( "save.asp", { id: 1, value: "abcxyz" } ); to pass the values to my ASP classic file that will update the database. I don't need a return value (unless it fails). I'm a relative noob to jQuery, so I'm assuming I'm using JSON to pass the values to the ASP file. I just don't know what to do with them in ASP (using VBScript). I've seen things like ASP Extreme, but I'm not clear on how to use them. I've tried referencing values via the Request collection, but no luck. All I want to do is take the values passed, parse them out, then save them to the database. Sorry if this is a duplicate, but this just isn't clicking for me.

• What are the dark corners of Vim your mom never told you about?

  - by Sasha

  There is a plethora of questions where people talk about common tricks, notably this one. However, I don't refer to commonly used shortcuts that a noob would find cool. I am talking about a seasoned unix user (be she/he a developer, admin, both, etc), who thinks (s)he knows something 99% of us never heard or dreamed about. Something that not only makes his/her work easier, but also is COOL and hackish. After all, vim resides in the most dark-corner-rich OS in the world, thus it should have intricacies that only a few privileged know about and want to share with us.

• From actionscript to google's datastore through java.

  - by Jonathan

  I'm working on a flash game written in pure actionscript 3.0 in Flex. I've just finished implementing replays for the game, but want to store the top 10 hiscores' replay data on my google-app-engine'd website. I'm using Java for the app-engine stuff in Eclipse in java but I have no idea how to deal with communicating to my java code from my actionscript code. I'll need to both read and write from actionscript - java - datastore. Does anyone have any experience with this? For note, I'm horribly noob with anything to do with web development. I hear you can pass arguments to a URL when calling it, comparable to command-line arguments on a desktop executable and if so then sending all the data as a large string would be doable... The question then would be how to call a url from AS3 code with additional data and then how to catch that on the java side. Thanks to anyone who can help. Jono

• how can i make a link in XML

  - by Chi

  I have this flash website that comes with XML. The website is predefined in such a way that when I hoover the mouse cursor over some pictures or text, it will show the pointing hand, thus meaning it's a clickable link. Originally, it would look like so: After I changed the link part, it becomes: However, this seems not to be working (google link is just an example). The pointing hand is still showing, but when I click on it, nothing happens. So my question is quite simple, how do I link in XML (sorry if all this sounded rather stupid, I'm a noob)

• How do you install Castle Windsor IOC?

  - by user300266

  I'm currently reading Pro ASP.NET MVC Framework by Sanderson. In the book he recommends setting up IoC using Castle Windsor, and he points out that the download automatically installs it and registers the Castle DLLs in the GAC. Well, at this point in time (5/4/2010), the Castle Project no longer has a downloadable installer that sets this up. Its all broken out into their individual subprojects with the raw files contained in zipped folders. Sadly there's no installation documentation that I can find about how to set it up. Being the noob that I am, I'm stuck and now forced to ask #1 where should castle windsor live on my hard drive? #2 how do I manually register the dlls properly? And, #3 should I be angry at the project maintainers for their oversight? Here's the link: http://www.castleproject.org/castle/download.html

• Trying to find a good strategy using Git for personal development on local/personal machine

  - by AJ

  A noob here. I have a personal Macbook and I want to use Git to track the changes etc. I want to just init a repo on my macbook and work there. Is this a good idea? What if: I have a main repo somewhere in my Macbook HD, like, /Users/user/projects/project1 and clone it to another area on my macbook where I actually perform development? But there is a lot of redundancy in this. I am a little confused and want to know what are the usual steps folks take in a similar personal development environment. Thanks a lot.

• Specify Action on sub-controller when using Html.RenderAction

  - by iammaz

  I have a UserControl that I call with Html.RenderAction(...), so far so good.. Then I want to specify in the user control, which action should be used Html.BeginForm("DeleteComment", "Comments", new { Id = "frmDelete" }, FormMethod.Post);%> <%= Html.SubmitImage( "imgbtnDelete", "/image.png", new { ... })%> <% Html.EndForm(); %> And therein lies my problem; this calls the user control's controller/action. What I want to happen is to call the pages action first and then be able to specify what action to call on the user control's controller. Is this possible?? Thanks from an MVC noob

• Introduction tutorial/s for web accessibility?

  I've ignored this topic for really long time and I would like to get at least basic instincts on this subject (You know - more than "don't forget to add alt on images"). Assuming that I'm complete noob on this, where should i look first? Please, do not just post some ISO standards, html spec or whatnot. That will just recoil any interest. I'm looking for gentle push with guidelines where to look next. P.s. I did try to find duplicate question/s w/o any luck.

• PHP Exec command - How to pass input to a series of questions

  - by user556597

  I have a program on my linux server that asks the same series of questions each time it executes and then provides several lines of output. My goal is to automate the input and output with a php script. I know how to capture the output in an array by writing: $out = array(); exec("my/path/program",$out); But how do I handle the input? Assume the program asks 3 questions and valid answers are: left 120 n What is the easiest way using php to pass that input to the program? Can I do it somehow on the exec line? I’m not a php noob but simply have never needed to do this before. Alas, my googling is going in circles.

• Python - Linux - Connecting to MS SQL with Windows Credentials - FreeTDS+UnixODBC + pyodbc or pymssq

  - by Keith P

  There doesn't seem to be any great instructions for setting this up. Does anyone have any good instructions? I am a linux noob so be gentle. I did see another post that is similar, but no real answer. I have a couple of problems. FreeTDS doesn't "seem" to be working. I am trying to connect and I get the following message using the "tsql" command: "Default database being set to databaseName There was a problem connecting to the server" but it doesn't mention what the problem is. The error I get when I try to connect using pyodbc is: "pyodbc.Error: ('08S01', '[08S01] [unixODBC][FreeTDS][SQL Server]Unable to connect: Adaptive Server is unavailable or does not exist (20009) (SQLDriverConnectW)')" I tried something similar with pymssql, but I ran into similar issues. I keep getting errors that I can't connect, but it doesn't tell me why.

  I have a Flash app with a PHP backend. Whenever there is a PHP error, I get the "Channel Disconnected before an acknowledgement was received" error message. I'm getting ready to push my project to beta and I would prefer if this message said something more like "There was a PHP error, please log a bug" or something instead of a message they don't understand. Anyone know of a way for me to change this error message? BTW I'm pretty much a noob when it comes to Flash programming so please be descriptive. Using Flash Builder 4 Beta 2.

• Ajax Enabled WCF Service Javascript issue...

  - by Captain Insano

  I'm a noob working with Ajax-Enabled WCF Services... Right now I have an AJAX service which calls a different WCF service that is using wsHttpBinding. The WCF wsHttpBinding service lives in a different web app on the same IIS6 server. The AJAX javascript proxy is only created when I enable anonymous access on the app hosting the AJAX service. If I remove anonymous access, IE6 bombs with an 'Undefined' error when call the AJAX proxy. In a nut shell, my AJAX service sends a request back to IIS (same domain/app), and while on the server it sends a WCF service request for data on a different app on the same IIS server. The service returning data is setup with Windows authentication, wsHttpBinding, and security mode is set to message. Any ideas? Both apps have are using windows authentication.

• Microsoft Robotics Studio, simple simulation

  - by Arkapravo

  I am soon to start with Microsoft Robotics Studio. My question is to all the gurus of MSRS, Can simple simulation (as obstacle avoidance and wall following) be done without any hardware ? Does MSRS have 3-dimensional as well as 2-dimensional rendering? As of now I do not have any hardware and I am only interested in simulation, when I have the robot hardware I may try to interface it! Sorry for a silly question, I am a MSRS noob, but have previous robotics h/w and s/w experience.

• How to use Cassandra's Map Reduce with or w/o Pig?

  - by UltimateBrent

  Can someone explain how MapReduce works with Cassandra .6? I've read through the word count example, but I don't quite follow what's happening on the Cassandra end vs. the "client" end. https://svn.apache.org/repos/asf/cassandra/trunk/contrib/word_count/ For instance, let's say I'm using Python and Pycassa, how would I load in a new map reduce function, and then call it? Does my map reduce function have to be java that's installed on the cassandra server? If so, how do I call it from Pycassa? There's also mention of Pig making this all easier, but I'm a complete Hadoop noob, so that didn't really help. Your answer can use Thrift or whatever, I just mentioned Pycassa to denote the client side. I'm just trying to understand the difference between what runs in the Cassandra cluster vs. the actual server making the requests.

My aplication uses the Lucene 2.4.0 library with a custom similaraty implementation (the jar is imported) In my app im calculating doqFreq and numDocs manually (im adding the values of all indexes and then i calculate a global value in order to use it on every query) and i want to use that values on a custom similarity implementation in order to calculate a new IDF. The problem is that I dont know how to use (or send) the new doqFreq and numDocs values from my app on that new similarty implementation as I dont want to change lucene´s code apart from this extra class. Any suggestions or examples? I read the docs but i dont now how to aproach this :s Thanks

• iPhone connect to MySQL database on local network computer

The machine is behind the same gateway and has an ip address similar to 192.169.x.x. Is that possible without PHP in the middle or anything else for that matter? Thanks in advance.
