  • MySQL and Hadoop Integration - Unlocking New Insight

    - by Mat Keep
    “Big Data” offers the potential for organizations to revolutionize their operations. With the volume of business data doubling every 1.2 years, analysts and business users are discovering very real benefits when integrating and analyzing data from multiple sources, enabling deeper insight into their customers, partners, and business processes. As the world’s most popular open source database, and the most deployed database in the web and cloud, MySQL is a key component of many big data platforms, with Hadoop vendors estimating 80% of deployments are integrated with MySQL. The new Guide to MySQL and Hadoop presents the tools enabling integration between the two data platforms, supporting the data lifecycle from acquisition and organisation to analysis and visualisation / decision, as shown in the figure below The Guide details each of these stages and the technologies supporting them: Acquire: Through new NoSQL APIs, MySQL is able to ingest high volume, high velocity data, without sacrificing ACID guarantees, thereby ensuring data quality. Real-time analytics can also be run against newly acquired data, enabling immediate business insight, before data is loaded into Hadoop. In addition, sensitive data can be pre-processed, for example healthcare or financial services records can be anonymized, before transfer to Hadoop. Organize: Data is transferred from MySQL tables to Hadoop using Apache Sqoop. With the MySQL Binlog (Binary Log) API, users can also invoke real-time change data capture processes to stream updates to HDFS. Analyze: Multi-structured data ingested from multiple sources is consolidated and processed within the Hadoop platform. Decide: The results of the analysis are loaded back to MySQL via Apache Sqoop where they inform real-time operational processes or provide source data for BI analytics tools. So how are companies taking advantage of this today? As an example, on-line retailers can use big data from their web properties to better understand site visitors’ activities, such as paths through the site, pages viewed, and comments posted. This knowledge can be combined with user profiles and purchasing history to gain a better understanding of customers, and the delivery of highly targeted offers. Of course, it is not just in the web that big data can make a difference. Every business activity can benefit, with other common use cases including: - Sentiment analysis; - Marketing campaign analysis; - Customer churn modeling; - Fraud detection; - Research and Development; - Risk Modeling; - And more. As the guide discusses, Big Data is promising a significant transformation of the way organizations leverage data to run their businesses. MySQL can be seamlessly integrated within a Big Data lifecycle, enabling the unification of multi-structured data into common data platforms, taking advantage of all new data sources and yielding more insight than was ever previously imaginable. Download the guide to MySQL and Hadoop integration to learn more. I'd also be interested in hearing about how you are integrating MySQL with Hadoop today, and your requirements for the future, so please use the comments on this blog to share your insights.

  • Recovering Data from a Linkstation LS-WXL/R1

    - by kingkool68
    I've been running a Buffalo Linkstation LS-WXL/R1 in RAID1 for a few weeks. Two nights ago we had a brief power outage. Yesterday when I tried to mount the disk it couldn't be found. I logged in to the web admin and it couldn't see any storage attached and no arrays available. Well this sucks. I ended up taking the disks out and mounting them to an Ubuntu virtual machine. They how up as an Array but I can't start the Array to the best of my limited knowledge. I could still see the 6 partitions, so I'm confident the data is there. I can use Photorec (http://www.cgsecurity.org/wiki/PhotoRec) to recover most of the files I want, it just takes some time. Could I make an image of the data partition and mount that in Ubuntu so I can get at the data I want through the file system? 95% of the data on my Linkstation LS-WXL/R1 is backup. I just put a few folders of images on there that I need to get back. I'm already preparing to format the disks when I'm done and re-building the RAID1 array from scratch. Any advice would be appreciated.

  • What GPT partition type to use for protecting DRBD metadata?

    - by Carsten Scholtes
    I'm planning to install a DRBD device on a (replicated) disk with two GPT partitions. DRBD requires some space for (preferentially "internal") metadata at the end of the underlying device. I'm hesitant to leave this space unpartitionend (or unformatted in a normal partition). I'd like to reserve an extra partition at the end of the underlying disk device for the metadata. (If I understand correctly, DRBD would not care about the partition or its type and could then use that space exclusively.) My question is: Which would be a suitable GPT partition type for such a metadata partition? It should not be a type interpreted while booting (such as EF00 EFI System). It should not be a type prone to be modified accidentialy by the booted OS (such as 8200 Linux swap, 8e00 Linux LVM, fd00 Linux raid). (The booted OS will be Ubuntu Linux 12.04.3.) It should not be a type indicating a normal filesystem (such as 0c01 or 8301), prone to be formatted correspondingly. It should not be a type requiring any special content in the partition (since the content is to be handled exclusively by DRBD). It should express the purpose of being reserved for something special (namely DRBD). (The types I listed are as provided by gdisk. I'm thinking about using some type unlikely to be used by the OS (maybe bf0a Solaris Reserved 4) or an invented(?) type such as fd01 (close to fd00 Linux raid…). Would something like this be suitable, too dangerous or even possible?)

  • IIS FTP 7.5 Data Channel Problem (SSL)

    - by user59050
    Hey there I wonder if anyone can get me in the right direction. I am setting up both a FTPS Client and Server, FTPS Server using Microsoft’s iis FTP 7.5. On the client side it will be running on Linux and I am using M2crypto for the openssl wrapping (python). I am worried the problem is on the server side (iis7.5) due to the following discovery : If I host using Filezilla with BOTH the control and data channel being forced to be encrypted it works 100% (100% file transmission), if i use iis as the server everything works up to the point when the data channel takes over... i.e. all data of the retrieved file is already received correctly in my basket! The ftp server just won't send the final '226 Transfer complete.' on the cmd socket. Why? If i force the client or server to close the connection the file is 100% intact....If i use iis 7.5 with forced encryption on control channel all works 100% as long as i don’t force data channel... Here are some screenshots to demo this... Client View after Kill Client : pics @ http://forums.iis.net/p/1172936/1960994.aspx#1960994 Summary : We can establish the connection, do directory listings, start the upload, see the file (0bytes) created on the server but then the client hangs. If we terminate the client, the uploaded file on the server suddenly jumps up to full size.

  • Fast distributed filesystem for a large amounts of data with metadata in database

    - by undefined hero
    My project uses several processing machines and one storage machine. Currently storage organized with a MSSQL filetable shared folder. Every file in storage have some metadata in database. Processing machines executes tasks for which they needed files from storage and their metadata. After completing task, processing machine puts resulting data back in storage. From there its taken by another processing machine, which also generates some file and put it back in storage. And etc. Everything was fine, but as number of processing machines increases, I found myself bottlenecked myself with storage machines hard drive performance. So I want processing machines to put files in distributed FS. to lift load from storage machines, from which they can take data from each other, not only storage machine. Can You suggest a particular distributed FS which meets my needs? Or there is another way to solve this problem, without it? Amounts of data in FS in one time are like several terabytes. (storage can handle this, but processors cannot). Data consistence is critical. Read write policy is: once file is written - its constant and may be only removed, but not modified. My current platform is Windows, but I'm ready to switch it, if there is a substantially more convenient solution on another one.

  • How to Programmatically Split and Manipulate Rows of Data From Excel

    - by Charlene
    I am hoping one of you will be able to help get me started on this issue. I need to create some sort of macro or VBA code to split and manipulate rows of data in Excel. For this example, we have 5 rows of data. The first 3 rows are item information for Order # 0000000000-00 and the last 2 rows are item information for order # 0000000000-01. I need one row ("HDR") for each order number, and one row ("ITM") for each product per order. I have included an example below showing the data I will receive and the desired outcome. Raw Data: order-id product-num date buyer-name product-name quantity-purchased 0000000000-00 10000000000000 5/29/2014 John Doe Product 0 1 0000000000-00 10000000000001 5/29/2014 John Doe Product 1 2 0000000000-00 10000000000002 5/29/2014 John Doe Product 2 1 0000000000-01 10000000000002 5/30/2014 Jane Doe Product 2 1 0000000000-01 10000000000003 5/30/2014 Jane Doe Product 3 1 Desired Outcome: HDR 0000000000-00 John Doe 5/29/2014 ITM 10000000000000 Product 0 1 ITM 10000000000001 Product 1 2 ITM 10000000000002 Product 2 1 HDR 0000000000-01 Jane Doe 5/30/2014 ITM 10000000000002 Product 2 1 ITM 10000000000003 Product 3 1 Any and all help would be much appreciated!!!

  • How to publish internal data to the internet - as simple as possible

    - by mlarsen
    I Asked this at Staock Overflow, but I would like your oppinion too as it has as much to do with administration as it does with coding. We have a .net 2-tier application where a desktop program is talking to a database. We support MS SQL Server 2000, 2005, 2008 and Oracle 9, 10 and 11. The application is sold, not as shrink-wrap, but pretty close. It is quite important for us that the installation and configuration is as easy as possible as installation instructions are usually supplied in written form to the customers internal IT-department. Our application is usually not seen as mission critical for the IT-department, so we need to keep their work down to a minimum. Now we are starting to get wishes for a web application build on top of the same data. The web application will be hosted by us and delivered as a SaaS application. Now the challenge is how to move data back and forth between the web application and the customers internal database. as I see it we have some requirements: We must be ready to handle the situation where the customers database is not accessible from the DMZ. I guess the easiest solution is that all communication is initiated from inside the customers lan. As little firewall configuration as possible. The best is if we can run without any special configuration as long as outgoing traffic from the customers lan are not blocked. If we need something changed in the firewall, we must be able to document that the change is secure. It doesn't have to be real time. Moving data in batches every ten minutes or so is OK. Data moves both ways, but not the same tables, so we don't have to support merges. It would be nice if we don't have to roll our own framework completely. Looking forward to hear your suggestions.

  • Numbering grouped data in Excel

    - by Jeff
    I have an Excel spreadsheet (2010) with data similar to this: Dogs Brown Nice Dogs White Nice Dogs White Moody Cats Black Nice Cats Black Mean Cats White Nice Cats White Mean I want to group these animals but I only care about species and color. I don't care about disposition. I want to assign group numbers to the set as shown here. 1 Dogs Brown Nice 2 Dogs White Nice 2 Dogs White Moody 3 Cats Black Nice 3 Cats Black Mean 4 Cats White Nice 4 Cats White Mean I was able to select all the species and colors, then from the data tab select 'advanced', then 'unique records only'. This collapsed the data so that I could number the visible rows. Then when I 'cleared' the filter I could easily just fill the blank areas under the numbers with the number above. The problem is that my real data has far too many rows for this to be practical. Also, the trick about entering 1 in the first cell, 2 in the cell below, selecting both then dragging the corner down to 'auto-number' doesn't seem to work when you're viewing filtered rows. Any way to do this?

  • Using PHP Redirect Script together with Custom Fields (WordPress)? [on hold]

    - by Alex Scherer
    I am currently trying to make yoast's link cloaking script ( Yoast.com script manual // Github Script files ) work together with the Wordpress plugin Advanced Custom Fields. The script fetches 2 values (redirect id, redirect url) via GET and then redirects to this particular URL which is defined in a .txt file called redirects.txt I would like to change the script, so that I can define both the id and redirection URL via custom fields on each post in my WP dashboard.. I would be really happy if someone could help me to code something that does the same as the script above but without using a redirects.txt file to save the values but furthermore gets those values from custom fields. Best regards ! Alex

  • Android: Layouts and views or a single full screen custom view?

    - by futlib
    I'm developing an Android game, and I'm making it so that it can run on low end devices without GPU, so I'm using the 2D API. I have so far tried to use Android's mechanisms such as layouts and activities where possible, but I'm beginning to wonder if it's not easier to just create a single custom view (or one per activity) and do all the work there. Here's an example of how I currently do things: I'm using a layout to display the game's background as an image view and the square game area, which is a custom view, centered in the middle. What would you say? Should I continue to use layouts where possible or is it more common/reasonable to just use a large custom view? I'm thinking that this would probably also make it easier to port my code to other platforms.

  • Accidentally dd'ed an image to wrong drive / overwrote partition table + NTFS partition start

    - by Kento Locatelli
    I screwed up and set the wrong output for dd when trying to copy a freenas iso, overwriting the wrong external hard drive. Ironically, I was trying to setup a freenas server for data backup... External drive is only used for data storage, system is entirely intact Drive had a single NTFS partition filing the entire device (2TB WD elements) Drive originally had an MBR partition table. Drive now shows as having a GPT, presumably from the freenas image. Drive was mounted at the time, with maybe a couple kB of data written/read after running dd Drive is just a few months old and healthy (regular SMART / fs checks) I have not reboot the OS (crunchbang) /proc/partition still holds the correct information (and has been stored) Have dd's output (records in / out / bytes) testdrive did not find any partitions on quick or deep search running photorec to recover the more important data (a couple recent plaintext files that hadn't been backed up yet). Vast majority of disk content ( 80%) is unnecessary media files. My current plan is to let photorec do it's thing, then recreate the mbr with gparted and use cfdisk to create another NTFS partition using the sector information from /sys/block/.../. Is that a good course of action (that is, a chance of success)? Or anything else I should try first?

  • Updating with using custom class collection not working

    - by Risho
    I've posted this yesterday on asp forum but no one replied so perhaps I'll have better luck here. For some reason the OnUpdating method does not pull new values from the grid which is in edit mode. I've search and have come across several blogs and sites, some sugesting that an ObjectDataSource is required in order to use the "e.NewValue" construct others provide code to the contrary. I don't get any errors - the variables in the code file would contain the old values rather then new ones. I don't want to use the ODS way of manipulating the data. My delete method works but not the update one. Can you suggest what is wrong with the code? Here is what I've got: aspx file: <asp:GridView ID="gvBlack" runat="server" AutoGenerateColumns="False" OnRowUpdating="gvBlack_OnUpdating" OnRowEditing="gvBlack_RowEditing"> <Columns> <%--<asp:BoundField DataField="Ident_Black" ReadOnly="True" visible="false" />--%> <asp:TemplateField ItemStyle-Width="1px"> <EditItemTemplate> <asp:Label ID="lblIdent_Black" runat="server" Text='<%# Bind("Ident_Black") %>' Visible="false" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Model" > <ItemTemplate> <asp:Label ID="lblModel_Black" runat="server" Text='<%# Bind("Model_Black") %>' width="130px" /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtModel_Black" runat="server" Text='<%# Eval("Model_Black") %>' width="100px" /> <asp:RequiredFieldValidator ID="rfvModel_Black" runat="server" ControlToValidate="txtModel_Black" SetFocusOnError="true" ErrorMessage="*" ValidationGroup="CurrentMfg" ForeColor="Red" Font-Bold="true" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Description" > <ItemTemplate> <asp:Label ID="lblDesc_Black" runat="server" Text='<%# Bind("Desc_Black") %>' width="200px" /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtDesc_Black" runat="server" Text='<%# Eval("Desc_Black") %>' width="170px" /> <span></span> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Qty" > <ItemTemplate> <asp:Label ID="lblQty_Black" runat="server" Text='<%# Bind("Qty_Black") %>' width="35px" /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtQty_Black" runat="server" Text='<%# Eval("Qty_Black") %>' width="35px" /> <asp:RequiredFieldValidator ID="rfvQty_Black" runat="server" ControlToValidate="txtQty_Black" SetFocusOnError="true" ErrorMessage="*" ValidationGroup="CurrentMfg" ForeColor="Red" Font-Bold="true" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Reorder<br />Limit"> <ItemTemplate> <asp:Label ID="lblBlack_Reorder_Limit" runat="server" Text='<%# Bind("Black_Reorder_Limit") %>' width="35px" /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtBlack_Reorder_Limit" runat="server" Text='<%# Eval("Black_Reorder_Limit") %>' width="35px" /> <asp:RequiredFieldValidator ID="rfvBlack_Reorder_Limit" runat="server" ControlToValidate="txtBlack_Reorder_Limit" SetFocusOnError="true" ErrorMessage="*" ValidationGroup="CurrentMfg" ForeColor="Red" Font-Bold="true" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Notes"> <ItemTemplate> <asp:Label ID="lblNotes" runat="server" Text='<%# Bind("Notes") %>' width="200px" /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtNotes" runat="server" Text='<%# Eval("Notes") %>' width="170px" /> <span></span> </EditItemTemplate> </asp:TemplateField> <asp:CommandField ShowEditButton="True" ShowDeleteButton="false" ValidationGroup="CurrentToner" /> </Columns> </asp:GridView> aspx.cs file: protected void Page_Load(object sender, EventArgs e) { LoadData_TonerBlack(); } private void LoadData_TonerBlack() { dalConsumables_TonerBlack drTonerBlack = new dalConsumables_TonerBlack(); gvBlack.DataSource = drTonerBlack.GetListTonersBlack(); gvBlack.DataBind(); } protected void gvBlack_OnUpdating(object sender, GridViewUpdateEventArgs e) { //GridView gvBlack = (GridView)sender; //GridViewRow gvBlackRow = (GridViewRow)gvBlack.Rows[e.RowIndex]; int _Ident_Black = Convert.ToInt32(gvBlack.DataKeys[e.RowIndex].Values[0].ToString()); TextBox _txtModel_Black = (TextBox)gvBlack.Rows[e.RowIndex].FindControl("txtModel_Black"); TextBox _txtDesc_Black = (TextBox)gvBlack.Rows[e.RowIndex].FindControl("txtDesc_Black"); TextBox _txtQty_Black = (TextBox)gvBlack.Rows[e.RowIndex].FindControl("txtQty_Black"); TextBox _txtBlack_Reorder_Limit = (TextBox)gvBlack.Rows[e.RowIndex].FindControl("txtBlack_Reorder_Limit"); TextBox _txtNotes = (TextBox)gvBlack.Rows[e.RowIndex].FindControl("txtNotes"); string _updatedBy = Request.ServerVariables["AUTH_USER"].ToString(); dalConsumables_TonerBlack updateTonerBlack = new dalConsumables_TonerBlack(); updateTonerBlack.UpdateTonerBlack(_Ident_Black, _txtModel_Black.Text, _txtDesc_Black.Text, Convert.ToInt32(_txtQty_Black.Text), Convert.ToInt32(_txtBlack_Reorder_Limit.Text), _txtNotes.Text, _updatedBy); gvBlack.EditIndex = -1; LoadData_TonerBlack(); } protected void gvBlack_RowEditing(object sender, GridViewEditEventArgs e) { gvBlack.EditIndex = e.NewEditIndex; LoadData_TonerBlack(); } Thanks in advance!

  • Data loss by randomly unplugging the computer during runtime

    - by Kan
    I'm from Austria and we and the Germans have some sort of bad science-show which runs every day. What I call it would rougly translate to "half-knowledge" if you want so. By the way: It is called "Galileo". So they thought they'd make a computer myth busters video right now, and I couldn't believe what I saw and heard... The strangest thing to me was that they asked: "Does unplugging the computer damage your data?" Then they started up some machine with Vista on it, started copying some files and randomly unplugged the PC cable, the whole thing around 50 times. After their computer continued to start up normally, they just said "nothing can happen, your data or computer can't be damaged". They of course excluded unsaved data in running programs like text editors from this. I asked myself: What the hell are their "computer experts" saying? You can't tell by unplugging the cable 50 times if that can damage your computer. Can unplugging the cable during runtime cause data loss (as said by the moderator of the show)? (I destroyed my windows registry once during a reset)

  • Un-do Windows disk convert HFS+

    - by BLAKE
    Last night, a friend asked my to give him a copy of a word document. He handed me an external hard drive and left. I plugged the hard drive into my file server running Windows Server 2003, opened disk management and clicked OK. (I know that in Windows 2003 you need to manually assign a drive letter to external drives.) I then looked at the drive in disk management and it said that it was unallocated space. I called my friend and he said that there was data on the drive, but he used it with his Mac Book. Aperantly when I clicked OK in disk management I converted the from HFS+ file system to something else. Is there any way to undo the disk convert? I immediately removed the drive, so there was no writing to it. Windows did not format the drive, it just converted it. Is the data still there? All the data recovery programs I have are for windows, can they read the Mac file system? I need to get the data back, what can I do?

  • Best solution top keep data secure

    - by mrwooster
    What is the simplest and most elegant way of storing a small amount of data in a reasonably secure way? I am not looking for ridiculous levels of advanced encryption (AES-256 is more than enough) and I am only looking to encrypt a small number of files. The files I wish to encrypt are mostly comprised of password lists and SSH keys for servers. Unfortunately it is impossible to keep track of ever changing passwords for my servers (and SSH keys) and so need to keep a list of the passwords. Obviously this list needs to be secure, and also portable (I work from multiple locations). At the moment, I use a 10MB encrypted disk image on my mac (std .dmg AES-256) and just mount it whenever I need access to the data. To my knowledge this is very secure and I am very happy using it. However, the data is not very portable. I would like to be able to access my data from other machines (especially ones running linux), and I am aware that there are quite a few issues trying to mount an encrypted .dmg on linux. An alternative I have considered is to create a tar archive containing the files and use gpg --symmetric to encrypt it, but this is not a very elegant solution as it requires gpg to be installed on every system. So, what over solutions exist, and which ones would you consider to be the most elegant? Ty

  • Failed Software RAID0 on Linux - Attempting to recover data

    I have a two disk RAID0 software raid (not hardware raid) that is reported to have failed during boot and my OS won't start. Using a Live CD, I get the following output : sudo mdadm -E /dev/sdc1 /dev/sdd1 /dev/sdc1: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : 3710713d:fb301031:84b61247:d1d53e0f Name : HP-xw9300:0 Creation Time : Sun Sep 1 15:22:26 2013 Raid Level : -unknown- Raid Devices : 0 Avail Dev Size : 1465145328 (698.64 GiB 750.15 GB) Data Offset : 16 sectors Super Offset : 8 sectors State : active Device UUID : ad427cd2:9f885f57:7f41015f:90f8f6af Update Time : Sun Jun 8 12:35:11 2014 Checksum : a37407ff - correct Events : 1 Device Role : spare Array State : ('A' == active, '.' == missing) /dev/sdd1: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : 3710713d:fb301031:84b61247:d1d53e0f Name : HP-xw9300:0 Creation Time : Sun Sep 1 15:22:26 2013 Raid Level : -unknown- Raid Devices : 0 Avail Dev Size : 976771056 (465.76 GiB 500.11 GB) Data Offset : 16 sectors Super Offset : 8 sectors State : active Device UUID : 2ea0199d:cb08d9e7:0830448a:a1e1e348 Update Time : Sun Jun 8 13:06:19 2014 Checksum : 8883c492 - correct Events : 1 Device Role : spare Array State : ('A' == active, '.' == missing) GParted lists both disks, detects the flags as 'Raid' and lists the data usage.

  • ZFS & Deduplicating FLAC Data

    - by jasongullickson
    I'm experimenting with using ZFS to deduplicate a large library of FLAC files. The purpose of this is twofold: Reduce storage utilization Reduce bandwidth needed to sync the library with cloud storage Many of these files are of the same music tracks but from different physical media. This means that for the most part they are the same and usually close to the same size, which makes me think that they should benefit from block-level deduplication. However in my testing I'm not seeing good results. When I create a pool and add three of these tracks (identical songs from different source media) zpool list reports 1.00 dedupe. If I copy all of the files (make exact duplicates of the three) dedupe climbs, so I know that it is enabled and functioning, but it's not finding any duplication in the original collection of files. My first thought was that perhaps some of the variable header data (metadata tags, etc.) might be mis-aligning the bulk of the data in these files (the audio frames) but even making the header data consistent across the three files doesn't seem to have any impact on deduplication. I'm considering taking alternate routes (testing other dedupe filesystems as well as some custom code) but since we're already using ZFS and I like the ZFS replication options, I'd prefer to use ZFS dedupe for this project; but perhaps it's simply not capable of working well with this sort of data. Any feedback regarding tuning that might improve dedupe performance for this sort of dataset, or confirmation that ZFS dedupe is not the right tool for this job are appreciated.

  • Un-do Windows disk convert HFS+

    - by BLAKE
    Last night, a friend asked my to give him a copy of a word document. He handed me an external hard drive and left. I plugged the hard drive into my file server running Windows Server 2003, opened disk management and clicked OK. (I know that in Windows 2003 you need to manually assign a drive letter to external drives.) I then looked at the drive in disk management and it said that it was unallocated space. I called my friend and he said that there was data on the drive, but he used it with his Mac Book. Aperantly when I clicked OK in disk management I converted the from HFS+ file system to something else. Is there any way to undo the disk convert? I immediately removed the drive, so there was no writing to it. Windows did not format the drive, it just converted it. Is the data still there? All the data recovery programs I have are for windows, can they read the Mac file system? I need to get the data back, what can I do?

  • Show (copy) data at "X" time and stop update

    - by Anka
    I have two sheets. In the first sheet, cell F4, I have 00:00:00 (countdown). G9, G10 and G11 are cells that receive live data (decimal numbers). In the second sheet, I have three cells linked from sheet1, G9 ='Sheet1'!G9, G10 ='Sheet1'!G10, G11 ='Sheet1'!G11 (which update themselves when data is modified in the first sheet). Now I want to set in sheet 2, (assume) cells B9, B10 and B11 to show me (copy) the values from G9, G10 and G11 from sheet 1 when the countdown was 00:00:05 (5 seconds before Start) and not update again if the data changes in the cell it pulled the data from. Like G9 ='Sheet1'!G9 at 00:00:05 and stop here, do not update anything. OK? I can do a part, but the real problem is: I can not make it stop cells to update. Stand frozen, freeze, not move, calm .. however. I do not want to seem pretentious (but my knowledge in excel is limited), the most appropriate would be a formula, not macro or VBA, if possible. I want to post a picture but I can not because of my restrictions. Well, if this is not possible with a formula is just fine with (not really) VBA.

  • Using Microsoft.Reporting.WebForms.ReportViewer in a custom SharePoint WebPart

    - by iHeartDucks
    I have a requirement where I have to display some data (from a custom db) and let the user export it to an excel file. I decided to use the ReportViewer control present in Microsoft.Reporting.WebForms.ReportViewer. I added the required assembly to the project references and I add the following code to test it out protected override void CreateChildControls() { base.CreateChildControls(); objRV = new Microsoft.Reporting.WebForms.ReportViewer(); objRV.ID = "objRV"; this.Controls.Add(objRV); } The first error asked me to add this line in the web.config which I did and the next error says The type 'Microsoft.SharePoint.Portal.Analytics.UI.ReportViewerMessages, Microsoft.SharePoint.Portal, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' does not implement IReportViewerMessages Is it possible to use ReportViewer in my custom Web Part? I rather not bind a repeater and write my own export to excel code. I want to use something which is already built by Microsoft? Any ideas on what I can reuse? Edit I commented the following line <add key="ReportViewerMessages"... and now my code looks like this after I added a data source to it protected override void CreateChildControls() { base.CreateChildControls(); objRV = new Microsoft.Reporting.WebForms.ReportViewer(); objRV.ID = "objRV"; objRV.Visible = true; Microsoft.Reporting.WebForms.ReportDataSource datasource = new Microsoft.Reporting.WebForms.ReportDataSource("test", GroupM.Common.DB.GetAllClientCodes()); objRV.LocalReport.DataSources.Clear(); objRV.LocalReport.DataSources.Add(datasource); objRV.LocalReport.Refresh(); this.Controls.Add(objRV); } but now I do not see any data on the page. I did check my db call and it does return a data table with 15 rows. Any ideas why I don't see anything on the page?

return View(); } If I use attribute [Authorize] then everything works ok, but if I use [Authorize(Roles="admin")] then user is always rejected, like he is not in role. Any idea of what could be wrong here? Thanks in advance, Ile

  • How to add custom SOAP-Header element to the generated WSDL in Spring-WS

    - by Petr Macek
    Hi, we are migrating from WebLogic web-services to Spring-WS (1.5.X). There is currently one issue we are facing: We need to pass a context object (on WLS it is passed as SOAP-Header element) to other services that are still running on WLS from the Spring-WS powered service. The header element is still formulated on client side and the newly created WS (Spring-WS) should just pass it to other services. I can imagine how the custom element would be passed: override the doWithMessage(WebServiceMessage message) method... Is there a way to generate the wsdl with the help of DefaultWsdl11Definition to contain that custom header element? See the example: <wsdl:operation name="GetSomeInformation"> <soap:operation soapAction="http://www.dummyservice.com/InformationService/GetSomeInformation" /> <wsdl:input> <soap:body use="literal" /> <soap:header message="ctx:ServiceContextMessage" part="serviceContext" use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> <wsdl:fault name="Error"> <soap:fault name="Error" use="literal" /> </wsdl:fault> </wsdl:operation> Thanks for help

  • WPF 4.0 Custom panel won't show dynamically added controls in VS 2010 Designer

    - by Matt Ruwe
    I have a custom panel control that I'm trying to dynamically add controls within. When I run the application the static and dynamically added controls show up perfectly, but the dynamic controls do not appear within the visual studio designer. Only the controls placed declaratively in the XAML appear. I'm currently adding the dynamic control in the CreateUIElementCollection override, but I've also tried this in the constructor without success. Public Class CustomPanel1 Inherits Panel Public Sub New() End Sub Protected Overrides Function MeasureOverride(ByVal availableSize As System.Windows.Size) As System.Windows.Size Dim returnValue As New Size(0, 0) For Each child As UIElement In Children child.Measure(availableSize) returnValue.Width = Math.Max(returnValue.Width, child.DesiredSize.Width) returnValue.Height = Math.Max(returnValue.Height, child.DesiredSize.Height) Next returnValue.Width = If(Double.IsPositiveInfinity(availableSize.Width), returnValue.Width, availableSize.Width) returnValue.Height = If(Double.IsPositiveInfinity(availableSize.Height), returnValue.Height, availableSize.Height) Return returnValue End Function Protected Overrides Function ArrangeOverride(ByVal finalSize As System.Windows.Size) As System.Windows.Size Dim currentHeight As Integer For Each child As UIElement In Children child.Arrange(New Rect(0, currentHeight, child.DesiredSize.Width, child.DesiredSize.Height)) currentHeight += child.DesiredSize.Height Next Return finalSize End Function Protected Overrides Function CreateUIElementCollection(ByVal logicalParent As System.Windows.FrameworkElement) As System.Windows.Controls.UIElementCollection Dim returnValue As UIElementCollection = MyBase.CreateUIElementCollection(logicalParent) returnValue.Add(New TextBlock With {.Text = "Hello, World!"}) Return returnValue End Function Protected Overrides Sub OnPropertyChanged(ByVal e As System.Windows.DependencyPropertyChangedEventArgs) MyBase.OnPropertyChanged(e) End Sub End Class And my usage of this custom panel <Window x:Class="MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:CustomPanel" Title="MainWindow" Height="364" Width="434"> <local:CustomPanel1> <CheckBox /> <RadioButton /> </local:CustomPanel1> </Window>
