    I have this DVB+Analog usb tv tuner Hauppauge WinTV HVR-900 (r2) [USB ID 2040:6502]. This used to work under ubuntu 10.04 LTS. But in 12.04 there seems to be a problem.

  • Why can't windows see mmcblk0p3? [closed]

    - by jacknad
    The partition is created on the embedded linux target like this # n - new # p - partition # 3 - partition 3 # 66 - starting cylinder # <blank> - maximum size for the ending cylinder # t - set file system type # 3 - partition 3 # c - set to windows vfat # w - write partition table and exit echo -e "n\np\n3\n66\n\nt\n3\nc\nw" | fdisk /dev/mmcblk0 The file system is then formatted on the embedded linux target as MS-DOS like this # -n volume-name # -F FAT-size mkfs.vfat -n DB -F 32 /dev/mmcblk0p3 A linux host can mount and access files in mmcblk0p3 without issue. Why can't windows? Edit: Although the default number of FATS is 2 I tried adding -f 2 [number-of-FATs] since this is actually being done by busybox on an embedded platform but this didn't help. I understand the Linux MS-DOS file system does not support more than 2 FATs but there are only 2 on this target (the boot is also FAT which is visible), along with and EXT3 (on p2) for the root file system.

  • How does Google Analytics aggregate the Count of Visits (Frequency & Recency Report)?

    - by Brian Dant
    Here's my simple understanding of Count of Visits: Each person that comes to my site gets one "count" for each visit. They are put into a bucket of people with the same number of total counts -- if you visit twice, you are in the two bucket, if you visit six times, you are in the six bucket. From there, a report (Frequency & Recency) makes a line for each bucket and reaches into the bucket and totals the number of people in that bucket, putting that total in the second column. My Question: Will a two month report automatically put someone into two buckets, and put them on two separate lines in the Count of Visits table? This explaination makes it seem like a two-month long report will put the same person into a bucket twice, one bucket for each month. The two-month report will then show that person's visits on two different lines, instead of aggregating them. Example for Clarification: Bob comes to my site three times in January and seven times in February. I run a report for Jan 1 -- Feb 28. Will Bob be on both the Three Count line and the Seven Count line, or will he be on the Ten Count line?

  • What is the best approach for database design with lots of columns?

    - by Pratyush
    I am writing a query based financial application. It lets the user to write complicated equations (much like WHERE part of an SQL query) and find companies matching those criteria. For the above, I currently have more than 500 columns in the database table (each column representing a financial field). Example of Columns are: company_name, sales_annual_00, sales_annual_01, sales_annual_02, sales_annual_03, sales_annual_04, protit_annual_00, profit_annual1...(over 500 such columns). The number of rows is around 5000. Going forward, I would like to further increase the number of columns/financial-fields. For the above I would like to get help regarding: 1) What is the best database design approach? Is it ok to have these many number of columns? 2) How can it be normalized? (User can use any of these fields in search criteria). 3) Is it ok to stick with MySQL, or modern document based databases like MongoDB should be better for it? P.S. (Update): I have been using MySQL till now and a running example of the usage is at: http://screener.in/companies/89/Formula-- In above there around 500 fields/columns to create your query on, however, I seek to increase that number to much more in future.

  • Unable to mount NTFS Partition after resizing

    - by sam
    I was having only 15 GB space allocated to LINUX. I wanted to have more space available to linux. So I just re sized one of my ntfs partition using GParted. But after resizing I am not able to open the partition neither in Ubuntu nor in windows. OS: Dual Boot Win7/Ubuntu 10.10 The error message i get is the following: Error mounting: mount exited with exit code 12: Failed to read last sector (395458824): Invalid argument HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS), or the NTFS boot sector is corrupt (NTFS size is not valid). Failed to mount '/dev/sda5': Invalid argument The device '/dev/sda5' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

  • hudson/jenkins: help needed to get started with customization work

    - by user64204
    I'm would to customize jenkins by adding links to the left hand side panel and use the pages associated with these links to serve some custom content in place of the jobs/views table displayed by default. I managed to add links to the side-bar using the sidebar-links plugin. Now I'm trying to see how to replace the content of the <td id="main-panel"> element with some custom content. The custom content is generated by some PHP scripts which ideally should be called by hudson every time the custom pages are requested, though if too complicated I can either create static content to be served by jenkins by calling my PHP scripts in a crontab or see if calls to the PHP scripts can be done by apache itself before the page requests are sent to jenkins. I'm not sure writing a plugin is the best way to proceed and I would like to have your thoughts as to how you think I should implement this.

  • Speeding up ROW_NUMBER in SQL Server

    - by BlueRaja
    We have a number of machines which record data into a database at sporadic intervals. For each record, I'd like to obtain the time period between this recording and the previous recording. I can do this using ROW_NUMBER as follows: WITH TempTable AS ( SELECT *, ROW_NUMBER() OVER (PARTITION BY Machine_ID ORDER BY Date_Time) AS Ordering FROM dbo.DataTable ) SELECT [Current].*, Previous.Date_Time AS PreviousDateTime FROM TempTable AS [Current] INNER JOIN TempTable AS Previous ON [Current].Machine_ID = Previous.Machine_ID AND Previous.Ordering = [Current].Ordering + 1 The problem is, it goes really slow (several minutes on a table with about 10k entries) - I tried creating separate indicies on Machine_ID and Date_Time, and a single joined-index, but nothing helps. Is there anyway to rewrite this query to go faster?

  • How can I delete, break, or otherwise convert cross references to simple text in microsoft word 2013

    - by Mr Purple
    Cross referencing figure and table captions is useful while editing a document but can become confude when copying and pasting between large documents. I need to pass my document to a colleague who will collate my document with others and has requested that I remove or delete any cross referencing so that my "correct" cross references do not interfere or get interfered with by any other cross references that may be in my colleagues master collated document. My document will be cut and pasted into the master and no further complicated instructions after that point will be tolerated by my colleague. Is there a simple way to convert my cross references to simple text? I am using microsoft word 2013.

  • 'Object variable or With block variable not set' error when setting a range in VBA

    - by David Gard
    I have a function that creates a Pivot Table, but I am getting an error when I try to set a range that will be merged and have a title added to it. In the below code, pivot_title_range is a 'String' variable, and is optional when calling the funtion. title_range is a 'Range' variable. Both lines that set the range (whether or not the users declares pivot_title_range) cause the same error. If pivot_title_range = "" Then title_range = ActiveSheet.Range("B3:E4") Else title_range = ActiveSheet.Range(pivot_title_range) End If Here is the error that I am getting - Run-time error '91': Object variable or With block variable not set If required, here is a Pastebin of the full function - http://pastebin.com/L711jayc. The offending code starts on line 160. Is anybody able to tell me what I am doing wrong? Thanks.

  • Should I split my website into different servers

    - by Nyxynyx
    I have a website where a user uploads photos, the photos gets resized and thumbnailed, and stored on the server. At the same time, there are some INSERTS into a MySQL table regarding the photo uploaded (like description, user id etc). The site currently runs off a managed VPS, and I love the support it provides. However it is expensive to store the many small photos and the resizing and thumbnailing processes do cause spikes on the app performance. (Amazon S3 is pretty expensive, especially considering the costs for uploading many small files) Question: Will it be a good idea to move the image processing operations and image storage to another server which is an unmanaged dedicated server with a much lower cost/gb and keep the current VPS for its 24/7 support and hosting the webapp? Or should I move the entire site to the dedicated server?

  • Is there an excuse for short variable names?

    - by KChaloux
    This has become a large frustration with the codebase I'm currently working in; many of our variable names are short and undescriptive. I'm the only developer left on the project, and there isn't documentation as to what most of them do, so I have to spend extra time tracking down what they represent. For example, I was reading over some code that updates the definition of an optical surface. The variables set at the start were as follows: double dR, dCV, dK, dDin, dDout, dRin, dRout dR = Convert.ToDouble(_tblAsphere.Rows[0].ItemArray.GetValue(1)); dCV = convert.ToDouble(_tblAsphere.Rows[1].ItemArray.GetValue(1)); ... and so on Maybe it's just me, but it told me essentially nothing about what they represented, which made understanding the code further down difficult. All I knew was that it was a variable parsed out specific row from a specific table, somewhere. After some searching, I found out what they meant: dR = radius dCV = curvature dK = conic constant dDin = inner aperture dDout = outer aperture dRin = inner radius dRout = outer radius I renamed them to essentially what I have up there. It lengthens some lines, but I feel like that's a fair trade off. This kind of naming scheme is used throughout a lot of the code however. I'm not sure if it's an artifact from developers who learned by working with older systems, or if there's a deeper reason behind it. Is there a good reason to name variables this way, or am I justified in updating them to more descriptive names as I come across them?

  • Editing the Microsoft Security Essentials context-menu

    - by GPX
    As all MSE users would know, the context-menu item that it adds to Explorer is really long, with one whole sentence "Scan with Microsoft Security Essentials...". Is there a way to edit this and shorten it? I figured out the the file shellext.dll is responsible for registering the context menu. I used ResEdit to edit the DLL and changed the string table entry from Scan with ($BrandName) to Scan with MSE. But it still won't change. I've also tried de-registering the DLL and then registering it again. No luck! Any ideas? Or am I doing something wrong?

  • Word Macro: Move Cursor Down a Row

    - by Bryan
    I have a macro which I've been using to merge two cells together in a word table, but what I want to do is to get the cursor to move down by one cell, so that I can repeatedly press the shortcut key to repeat the command over and over. The macro code that I have (shamelessy copied and pasted from a web page), is as follows: Sub MergeWithCellToRight() ' ' MergeWithCellToRight Macro ' ' Dim oRng As Range Dim oCell As Cell Set oCell = Selection.Cells(1) If oCell.ColumnIndex = Selection.Rows(1).Cells.Count Then MsgBox "There is no cell to the right?", vbCritical, "Error" Exit Sub End If Set oRng = oCell.Range oRng.MoveEnd wdCell, 1 oRng.Cells.Merge Selection.Collapse wdCollapseStart End Sub I've attempted to add the following line just before the 'End Sub' statement Selection.MoveDown wdCell, 1 but this generates the error, Run-time error '4120' Bad Parameter whenever I execute the macro. Can anyone tell me how to correct this or what I'm doing wrong?

  • Dialing into multiple PPP connections on Ubuntu

    - by sharjeel
    I have multiple 3G USB based Modems. I would like them to keep connected simultaneously, NOT necessarily aggregating their bandwidth; a separate intelligent application would manage their utilization effectively. However I am running into problem of setting up proper routes for the ppp0,ppp1 interfaces: when one of them connects, other's entries in the routing table get updated so it is no more usable. If I reconnect the second one, it would override the first one's routing entries. If I do it over and over, sometimes both of them's entries disappear while in rare cases the two work well. I have tried it both using NetworkManager as well as WVDial but issue pops up in both of these. Perhaps both of them use same PPP dialer at the backend and thats why this issue appears. What is the proper solution to make them work together? In the long run, I'd also like them to automatically dial in once USB gets connected.

  • What is the proper way to pass the parameters into a MVC system?

    - by gunbuster363
    I am trying to learn java servlet/jsp with the MVC concept and built the simplest MVC application. Now I want give more detail to it to enhance my understanding. If I would need to register a new row in a table in the database, how should we pass the various value of column into the system? For example, the user might want to register a new event in his planner and the detail of the event involves the 'where', 'when', 'who', 'detail', etc. Should pass all this long value from the servlet's parameter, i.e: the http link? String accNo = request.getParameter("account_number"); String a = request.getParameter("..."); String b = request.getParameter("..."); String c = request.getParameter("..."); String d = request.getParameter("..."); To illustrate my view that it is really unprofessional to show all the parameter on the link: http://localhost:8080/domain1/servlet1?param1=55555555555555&param2=666666666666666666666666666666666666666666666666666666666666&param3='Some random detail written by user.........................' Is there other way to pass them?

  • Defining work days and work time

    - by user2553268
    I'm working on development of SMS parking software, and I'm stuck at one point for a month... I need to implement periods of payment (or work time, of a work day, if you will). Here's the problem: For an example, traffic wardens work from Monday to Saturday. From Monday to Friday, the work times are from 07:00 to 21:00, and on Saturday, the work time is from 07:00 to 14:00. The project request was, that the customer can pay parking by SMS unlimited, which I did, but didn't implement this logic. I started with making a table for this periods of payment, it consists of: dayofweek (INT, for use with mysql function DAYOFWEEK, to tell me which day in week is the current date), work_start and work_stop (DATETIME, for defining starting and ending the work day), but I'm unsure if I should use DATETIME, beacuse of the date, or should I use only TIME. The idea is this: If you send an SMS, at 20:50, Monday, it should be valid until 07:50, Tuesday (it's payed by the hour). Extending the time of payment, regarding the work time in week. Currently, it works with extending time by the hour without this rule. Really would use some help, or some ideas, I'm stuck with this for quite some time...

  • Installing Xubuntu alongside with UEFI

    - by Geo
    For the past week and a half I have been trying to figure out how to install Xubuntu 13.10 alongside the Windows 7 install I have on my laptop (ASUS X501A with UEFI) and I'm pretty much at my wit's end. Could someone point me to set of thorough instructions on installing Xubuntu (or any of the Ubuntu derivatives) on a HDD under UEFI alongside Windows 7 64-bit Home Premium? Preferably one that also covers GRUB/bootloader problems that come afterwards. A few additional details: Motherboard does have UEFI. I've disabled Secure Boot and Fast Boot. Launch CSM is enabled and the platform keys are not installed (these settings allow me to at least boot Windows 7). I set the HDD's partition table to GPT through GParted before I installed Windows. I'm installing from a bootable USB that has been created through a tool called Rufus with the GPT partition scheme for UEFI computers option, otherwise I've left it at default. I am able to boot into Xubuntu in UEFI mode, but I'd much rather be able to see the option: Install Xubuntu Alongside Windows 7 (or however it's phrased), Xubuntu seems to be unable to recognize that Windows 7 is installed. I do have access to a bootable USB stick containing GParted though Xubuntu seems to come preinstalled with it. If there's anything else that might be of help, please let me know.

  • When does implementing MVVM not make sense

    - by Kelly Sommers
    I am a big fan of various patterns and enjoy learning new ones all the time however I think with all the evangelism around popular patterns and anti-patterns sometimes this causes blind adoption. I think most things have individual pros and cons and it's important to educate what the cons are and when it doesn't make sense to make a particular choice. The pros are constantly advocated. "It depends" I think applies most times but the industry does a poor job at communicating what it depends ON. Also many patterns surfaced from inheriting values from previous patterns or have derivatives, which each one brings another set of pros and cons to the table. The sooner we are more aware of the trade off's of decisions we make in software architecture the sooner we make better decisions. This is my first challenge to the community. Even if you are a big fan of said pattern, I challenge you to discover the cons and when you shouldn't use it. Define when MVVM (Model-View-ViewModel) may not make sense in a particular piece of software and based on what reasons. MVVM has a set of pros and cons. Let's try to define them. GO! :)

  • How to move ubuntu 12.04 on another drive

    - by Maksim
    How I can move my ubuntu on another drive? I know about clonezilla but problem is that destination drive is smaller the source one. Gparted can't copy-paste partition if destination not the end last partition. I tried dpkg --selected-packages and apt-clone. First one just not install all my packages and removed existed that now I have no full unity and not my all packages. Second one just fail on configuration package. But before I did that way I copy-paste my /etc to new system. My partition table destination : gpt 1 1049kB 106MB 105MB fat32 EFI System ??????????? 2 106MB 12,1GB 12,0GB ext4 3 12,1GB 66,3GB 54,2GB ext4 source: msdos 1 1049kB 12,0GB 12,0GB primary ext4 ??????????? 2 12,0GB 492GB 480GB primary ext4 3 492GB 500GB 8107MB primary linux-swap(v1) Gpt not working with ubuntu that use grub 1.99. I don't know why but my laptop can't boot any device with uefi just black screen and ubuntu detect it on fresh install.

  • "Missing Operating System" after installing Ubuntu 12.04 from a CD on a Macbook Pro

    - by Pierre
    I followed this guide to install Ubuntu 12.04 on my Macbook Pro 8,2 (late 2011): https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation I used a CD. I synced the partition table on rEFIt, and it went fine. I do have an icon to boot on Linux, but when I launch it, after a few seconds I have "Missing Operating System" displayed, and that's all... How can I fix that? The only thing I see is, in the guide, it is mentioned this: On the last dialog of the installer, be sure to click the “Advanced” button and choose to install the boot loader (grub) to your root Ubuntu partition, for example /dev/sda3. This will be the only partition with the EXT4 file system. In Ubuntu 12.04 installation process, there is not such an option, but there is a dropdown menu to select where the grub bootloader should be installed. It was /dev/sda by default, but I selected my root Ubuntu partition (in my case, /dev/sda5). I got a warning message (but actually, it was the same warning message even when I selected /dev/sda), and I continued the installation... Thanks in advance for your help!

  • Using e-mail address as user name for SMTP and POP3

    - by PeterMmm
    I have a exim4 setup as SMTP. My user naming schema is to name all mail users for this server as m001, m002, m003, ... and then redirect to a real e-mail address with virtual domains. How can I allow my users to authenticate with exim to send mail using either their system user name (m001) or the email address ([email protected])? User login information for m001 are stored in linux system files (passwd, shadow). They are linked thru entries in a virtual address table for each domain that this server can serve: # /etc/exim4/virtual/example.com m001: [email protected] m002: [email protected] m003: [email protected] The same can be applied to qpopper ?

  • Turn-based Client-Server Card Game - Unicast (TCP) or Multicast (UDP)

    - by LDM91
    I am currently planning to make a card game project where the clients will communicate with the server in a turn-based and synchronous manner using messages sent over sockets. The problem I have is how to handle the following scenario: (Client takes it turn and sends its action to server) Client sends a message telling the server its move for the turn (e.g. plays the card 5 from its hand which needs to placed onto the table) Server receives messages and updates game state (server will hold all game state). Server iterates through a list of connected clients and sends a message to tell of them change in state Clients all refresh to display the state This is all based on using TCP, and looking at it now it seems a bit like the Observer pattern. The reason this seems to be an issue to me is this message doesn't seem to be point-to-point like the others as I want to send it to all the clients, and doesn't seem very efficient sending the same message in that way. I was thinking about using multicasting with UDP as then I could send the message to all the clients, however wouldn't this mean that the clients would in theory be able to message each other? There is of course the synchronous aspect as well, though this could be put on top of the UDP I guess. Basically, I would like to know what would be good practice as this project is really all about learning, and even though it won't be big enough to encounter performance issues from this I would like to consider them anyway. However, please note I am not interested in using message oriented middleware as a solution (I have experience with using MOM and I'm interested in considering other options excluding MOM if TCP sockets is a bad idea!).
