• What do you call the concept of dynamic data definition?

  - by DJTripleThreat

  Maybe this is simpler and more straightforward then what I'm thinking but I can't seem to find this concept on google anywhere. The concept is this: You have a table in a database and the table has a specified number of columns. However, it has been asked of me by previous clients that there also be a set of dynamic user defined columns that can be added on the fly. What is this concept called and is it considered a design pattern?

• Recomposing data structure in Excel

  - by Velletti

  I've got a sheet of 35k rows of the following kind of data that I want to reshape into table below. So, I want to reshape this data in a way to get all the people within a specific GroupID in separate columns. I suppose that I should add a counter for each row within specific group id? Also, I suppose these kind of issues are a lot more comfortable to be done in databases? Since I often have this kind of data, I need be much quicker about solving it, then I am now.

• Can anybody recommend a good data recovery strategy?

  - by Jurassic_C

  So lets say you've failed at preventing a drive failure, and also, you've failed to make a backup of said drive. Push has come to shove and now you need a way to recover you're precious data. Has anybody out there run into this situation? And if so could you please provide any suggestions on how to recover the data based on your experiences? For example have you used any data recovery services that you could either recommend, or that you would definitely avoid if you had a do-over? Thanks in advance

• How to keep windows 2003 Daylight Saving values updated

  - by SirMoreno

  My web app runs on windows 2003 .Net 3.5 I have users from Israel (GMT +2), and Israel switched to Daylight saving time on 26/3/10 so now it's (GMT +3). I use TimeZoneInfo.ConvertTime that doesn’t know the Daylight saving time switch is on 26/3/10 so it still converts to GMT +2. I asked on StackOverflow: http://stackoverflow.com/questions/2530834/problem-with-timezoneinfo-converttime-missed-the-daylight-saving-switch/2532104#2532104 And I was told that I need to update: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\Israel Standard Time\Dynamic DST I found this update: http://support.microsoft.com/kb/976098 That supposes to fix the Dynamic DST for 2010, Is this the update I need? Where can I find an update that handles 2011 2012… ? Will I need to update my windows every year to get the DST right? Thanks.

• Data recovery on an Iomega portable drive.

  - by Kaji

  For Christmas, my little brother got an Iomega 500GB portable hard drive. It'd been working well, but last week it flat died, and the company's trying to shirk it, claiming it's not under warranty and saying it'll cost at least $900 to recover the data from the drive. He's still trying to fight the warranty thing, but wants to know, should it boil down to it, what other options exist for recovering the data from the drive. (in before "BACK UP!")

• Recovered folders from Camera show as JPEG files and can can't be viewed.

  - by user642111

  I have recovered a CCTV camera hard disk after a crash and have managed to get most of the data using EasyRecovery Pro. The problem is now that all the data that I have recovered appear like File09.JPG with and image icon in windows XP, but the files can't be viewed in any JPEG viewer software. I suspect that the .JPG files are indeed folders, but I can't force windows XP the change the file type. Very Odd. Any help is appreciated. Thanks, Hoo

• How often should saving to disk occur in an automatically saving text editor?

  - by lelandmiller

  I am developing a simple text editor and would like the application to save the text automatically. In other words, the user would never have to press a save button. I have seen other applications that do this, and was wondering how often is it safe to write files to disk? From a user experience standpoint, it seems that the more frequently this happens the better, but I am worried about performance and possible disk wear (especially on writes to SSDs). It seems like the operating system disk caching might help avoid these problems, but I also don't know if its safe to rely on that for an application like this. I was planning on writing the whole document to disk at each save, but this just seems terribly inefficient if the OS ends up writing it to disk to frequently, but relying on program unload may lose data in the case of a crash. Does anyone have any experience dealing with this that might be able to help?

• Saving all hits to a web app

  - by bevanb

  Are there standard approaches to persisting data for every hit that a web app receives? This would be for analytics purposes (as a better alternative to log mining down the road). Seems like Redis would be a must. Is it advisable to also use a different DB server for that table, or would Redis be enough to mitigate the impact on the main DB? Also, how common is this practice? Seems like a no brainer for businesses who want to better understand their users, but I haven't read much about it.

• Recover RAID 5 data after created new array instead of re-using

  - by Brigadieren

  Folks please help - I am a newb with a major headache at hand (perfect storm situation). I have a 3 1tb hdd on my ubuntu 11.04 configured as software raid 5. The data had been copied weekly onto another separate off the computer hard drive until that completely failed and was thrown away. A few days back we had a power outage and after rebooting my box wouldn't mount the raid. In my infinite wisdom I entered mdadm --create -f... command instead of mdadm --assemble and didn't notice the travesty that I had done until after. It started the array degraded and proceeded with building and syncing it which took ~10 hours. After I was back I saw that that the array is successfully up and running but the raid is not I mean the individual drives are partitioned (partition type f8 ) but the md0 device is not. Realizing in horror what I have done I am trying to find some solutions. I just pray that --create didn't overwrite entire content of the hard driver. Could someone PLEASE help me out with this - the data that's on the drive is very important and unique ~10 years of photos, docs, etc. Is it possible that by specifying the participating hard drives in wrong order can make mdadm overwrite them? when I do mdadm --examine --scan I get something like ARRAY /dev/md/0 metadata=1.2 UUID=f1b4084a:720b5712:6d03b9e9:43afe51b name=<hostname>:0 Interestingly enough name used to be 'raid' and not the host hame with :0 appended.

• SQL Developer Data Modeler v3.3 Early Adopter: Collaborative Design via Excel?

  - by thatjeffsmith

  As you may have heard last week, we have a new version of Oracle SQL Developer Data Modeler now available as an Early Adopter release. Version 3.3 has quite a few new features and I’ll be previewing them here. Today’s topic is our new Excel integration. It builds off of last week’s lesson: Search, so you may want to go read that first. They say it takes a village to raise a child. I say it takes a team to build a data model. You have your techie folks, your business folks, your in-betweeners, and your database geeks. Who gets to define how customers are represented and stored in your database? That data lives forever, so you better get it right from the beginning, or you’ll be living in a hacker’s paradise for years to come. Lots of good rantings, ravings, and advice on this topic in general on Karen Lopez’s (@datachick) blog. But let’s say you are the primary modeler on a project. You dutifully interview the business folks for their requirements. You sit down and start to model and think you’re pretty close. Now you need someone to confirm your assumptions and provide some feedback. Do you send your model over? Take a screenshot and blow it up on a whiteboard? Export to HTML and let them take a magic marker to their monitors? Or maybe you bite the bullet and install your modeling software on their desktops and take the hours or days required to train them up on how to use the the tool. Wouldn’t it be nice if they could just mark up their corrections in Excel and let you suck the updates back in? This is what we have started to build in Oracle SQL Developer Data Modeler. Let’s say you have a new table called ‘UT_STARTUPS.’ It looks a little something like this: A table in Oracle SQL Developer Data Modeler What I would like to do is have my team or co-worker review how I have defined those columns. Perhaps TIMESTAMP is overkill or maybe the column names themselves aren’t up to snuff. What I am going to do is now search for all the columns in my table, then export that to Excel. So do a search for UT_STARTUPS. Search, filter, then Report With the filter set to ‘Columns,’ if I do a report I’ll be only getting the columns that are resolving to my search term. So as long as my table name is unique in the model, I should get what I’m looking for. Here’s what I see when I click on the Report button: XLS or XLSX, either format is just fine I want to decide how the Column data is exported to Excel though, so I’m going to create a report template that I can use going forward. So click the ‘Manage’ button and setup a new template. I’m going to call mine ‘CollaborativeDevelopment.’ The templates allow me to define what properties are included in the reports. Once this is set, I’ll have the XLS file generated, and get to work Now let the Excel junkies do their stuff Note that not ALL of the report properties are update-able (yes, I made up a new word there) via Excel. We’ll have the full list of properties documented going forward, but in my Excel sheet, note that I can’t change the table name or the data types for the columns. I’m going to update some column names and supply ‘nice’ comments so the database users know what’s what. Here’s my input for the designer/architect/database dude: Be kind, please rew…use comments. Save the file, email it back to your modeler. Update the model from Excel That’s right, it’s a right mouse click from your model in the tree If everything goes right, you’ll see a nice confirmation message: It’s alive! Another to-do item on tap – making this dialog more informative. We’ll be showing exactly what in your model was updated from Excel. Let’s take another look at the model now Voila! Why are we doing this again? The goal is to reduce the number of round-trips from the modeler and the business process owner. One is used to working with Excel – why not allow them to mark up their changes in the tool they already know? This is an early adopter release and I anticipate this feature getting a good bit of tuning up before we release. Why don’t you download 3.3, give it a whirl, and let us know what you think?

• Webmin / Virtualmin running php as www-data, is locked out of viewing .htaccess and writing

  - by Kirill

  I've asked this on the virtualmin forums, but haven't had any help from there. Recently, "something" happened and it seems that the apache service has gone a bit weird. What it does: it runs all apache traffic as www-data and sometimes spawns the php5-cgi process as www-data, this is a problem because all the domain users own their directories and default permissions don't let www-data write to these folders (file uploads are dead) or read .htaccess (permalinks are broken in wordpress). I've googled this for about a week straight now, tried pretty much everything I could find and achieved nothing. The only thing that I think might actually be the cause of all this is this page: http:// - i.imgur.com/NYW3x.png (got shut down by the spam filter) So I figured if I set it to "default", this might magically start working again, but all it does is "crash" apache (all websites timeout). I figure it's something to do with the "mpm" module or something, but I can't find anything relevant in the settings to modify for it to work. Can someone please point me in the right direction? System info: Webmin version 1.580 Kernel and CPU Linux 2.6.35.4-rscloud on x86_64 Virtualmin version 3.90.gpl GPL Ubuntu 10.04 LTS (Lucid) A couple screenshots of top http://i.imgur.com/U2DTK.png http://i.imgur.com/sNPKs.png

• Hard drive failed, suspected filesystem corruption, still cannot salvage any data from harddrive

  - by Hippy-Head

  Firstly, I am terribly sorry if this is a duplicate, but I couldn't find a similar issue to mine, so here goes. I have a 1TB hdd bought around 8 months ago used as backup hard drive. I have not used the drive for a period of time whatsoever, and when I was trying to get back to some files on it, it was completely wiped just like that. At first it would not boot I tried everything from command line chkdsk and filesystem recovery software to rebuilt it. After a few attempts I managed to initialize it, at that time it was an achievement. The problems started when I tried to recover the data inside, I have used A LOT of software free and commercial software on both Mac and Windows, with the help of cmd or Terminal commands, however no data of any kind was recovered, even after leaving it thoroughly scan for around 9-10 hours all night sometimes longer, with no results at all. I am somewhat desperate, I am usually good at retrieving data from corrupt hard drives, but this is not the case. Call me paranoid, but I do not want to give it to someone to fix it for me, as I have a lot of photos and personal stuff that I do not want anyone to see.

• Cross OS data recover question, USB drive involved.

  - by Moshe

  Here's the story: A MacBook had OS X 10.4 and Windows XP dual booting using rEFIt. Then the Windows partition gets corrupted and it won't boot. Presumably a virus. There were sensitive files there and those were successfully copied to a USB drive and then 10.5 was installed on the hard drive, formatting the drive in the process. The USB drive's contacts cracked and he data is lost from there, unless it can be resoldered. The issues is that there is too much solder there already. So, how can the data in question be recovered? The files were Microsoft Money (not the latest version) files for the Windows version of the program. Right now, only OS X is installed on the MacBook. Is there Mac based program that can recover the Windows data or am I better off trying to resolder the drive? Does anyone know how to best resolder a USB drive more than once, where the first solder is ther, but detached from the silicon? Also, what format (extension) are Microsoft Money files? In need of help!

• Recover NTFS data from a ZFS pool that was exposed as an iSCSI target

  - by David

  This was me being stupid and the data is by no means critical and is now a learning experience first, time saver second. I set up a 100GB iSCSI target via the bare bone instructions in napp-it. It's a volume LU. I then had my Windows 7 machine connect to the iSCSI target, formatted it to NTFS, and tested the performance of it with some large iso file transfers. I then unmapped the drive, reconnected to the target, and was forced to format to NTFS again. It was then I realized the files I had transferred only existed on the iSCSI target. I threw a little fit and then went about my business. When I was cleaning up my experiment I noticed in this screen: http://imgur.com/1xlcu.jpg That is my experimental target tank/iSCSI and it still has a lot of data in it. Assuming my isos are still in this pool how would I go about recovering them? While writing this I used GetDataBackup for NTFS from www.runtime.org. And while it found two previous NTFS partitions there was no data.

• Share Firefox/Thnderbird data between W7 and Linux Mint 12 in dual boot computer

  - by Albert

  I've just set up my laptop (where I had running only W7) with a dual boot to run Linux Mint 12 as well. I have a "Data" partition (apart from the required partitions for W7 and Linux) where I store pretty much everything that isn't software installations (music, videos, project files, etc). I seem to be able to access that NTFS partition totally fine from Mint (like I've always done with W7), which is cool because I can access all that stuff regardless of which OS I'm using. I would like to know if it's possible (and how) to go one step further and share programs data between the two OS. One example would be my Firefox and Thunderbird data. For example, in Firefox share my bookmarks (and if I could share history, autocomplete and all that stuff, that would be awesome). In thunderbird, be able to share my mail and configuration, seeing the same inbox, folders, message rules, etc... So if I receive/send an email from W7 and later switch to Mint, I can see that email as it had been received/sent from Mint, and vice versa. Is this even possible? Or am I asking for too much convenience? If it's possible, any clues on how to set it all up?

• Recover data from Dynamic Disk (MBR) bigger than 2TB

  - by Helder

  Here is the situation: Promise Array FastTrak TX4310 with 3 disks (750 GB each) in RAID5. This comes to around 1500 GB of data. Last week I had the idea of expanding the RAID with an additional 750 GB disk. This would bring the volume to around 2250 GB. I plugged the disk and used the Webpam software to do the RAID expansion. However, I didn't count with the MBR 2TB limit, as I didn't remembered that the disk was using MBR instead of GPT and I didn't check it prior to the expansion. After a couple of days of expansion, today when I got home, the disk in Windows disk manager showed the message "Invalid disk" and when I try to activate it, it says "The operation is not allowed on the Invalid pack". From what I figured, the logical volume on the RAID expanded, and passed that info to the Windows layer and I ended up with an "larger than 2TB" MBR disk. I'm hopping that somehow I can still recover some data from this, and I was wondering if I can "rewrite" the MBR structure back to the 1500 GB partition size, so I can access the partition in Windows. Right now I'm doing an "Analyse" with TestDisk, as I hope the program will pickup the old 1500 structure and allow me to somehow revert back to it. I think that even though the Logical Drive in the RAID is bigger than the 2TB, I can somehow correct the MBR to show the 1500 GB partition again. I had a similar problem once, and I was able to recover the data using a similar method. What do you guys think? Is it a dead end? Am I totally screwed because there is the extra RAID layer that I'm not counting? Or is there other way to move with this? Thanks all!

• Subset a data.frame by list and apply function on each part, by rows

  - by aL3xa

  This may seem as a typical plyr problem, but I have something different in mind. Here's the function that I want to optimize (skip the for loop). # dummy data set.seed(1985) lst <- list(a=1:10, b=11:15, c=16:20) m <- matrix(round(runif(200, 1, 7)), 10) m <- as.data.frame(m) dfsub <- function(dt, lst, fun) { # check whether dt is `data.frame` stopifnot (is.data.frame(dt)) # check if vectors in lst are "whole" / integer # vector elements should be column indexes is.wholenumber <- function(x, tol = .Machine$double.eps^0.5) abs(x - round(x)) < tol # fall if any non-integers in list idx <- rapply(lst, is.wholenumber) stopifnot(idx) # check for list length stopifnot(ncol(dt) == length(idx)) # subset the data subs <- list() for (i in 1:length(lst)) { # apply function on each part, by row subs[[i]] <- apply(dt[ , lst[[i]]], 1, fun) } # preserve names names(subs) <- names(lst) # convert to data.frame subs <- as.data.frame(subs) # guess what =) return(subs) } And now a short demonstration... actually, I'm about to explain what I primarily intended to do. I wanted to subset a data.frame by vectors gathered in list object. Since this is a part of code from a function that accompanies data manipulation in psychological research, you can consider m as a results from personality questionnaire (10 subjects, 20 vars). Vectors in list hold column indexes that define questionnaire subscales (e.g. personality traits). Each subscale is defined by several items (columns in data.frame). If we presuppose that the score on each subscale is nothing more than sum (or some other function) of row values (results on that part of questionnaire for each subject), you could run: > dfsub(m, lst, sum) a b c 1 46 20 24 2 41 24 21 3 41 13 12 4 37 14 18 5 57 18 25 6 27 18 18 7 28 17 20 8 31 18 23 9 38 14 15 10 41 14 22 I took a glance at this function and I must admit that this little loop isn't spoiling the code at all... BUT, if there's an easier/efficient way of doing this, please, let me know!

• Core Data migration of to-one relationship to to-many relationship

  - by westsider

  I have a deployed app that samples measurements from sensors (e.g., Temp °C, Pressure kPa). The user can create Experiments and collect samples. Each sample is stored as a Run, such that there is a one-to-many relationship from Experiment to Run. In the interest of performance, Run has a to-one relationship with Data entity (which is where the actual raw data is stored); this allows some Run attributes to be loaded without necessarily loading lots of data. Most of our sensors have multiple measurements, so it would be nice to store all the data that is actually being sampled. But this means that the Run <--- Data relationship needs to become Run <-- Data (to use Xcode's convention). I am faced with trying to migrate data from old Run to-one Data model to new Run to-many Data model. Can this be done using Mapping Models? If so, does anyone have any pointers to examples? If not, does anyone have any pointers to examples of how to do that? Thanks for any pointers or advice.

• Reduce ERP Consolidation Risks with Oracle Master Data Management

It can translate to too much inventory, long lead times, and shipping issues from poorly organized and specified goods. And don’t forget the finance side! When goods are shipped and promises are kept/not kept there’s the issue of accounts. No single chart of counts translates to no accountability. So – I’ve decided. I need to consolidate! Well, you can’t consolidate ERP applications [for that matter any of your applications] without first considering your data. This means looking at how your data is being integrated by these ERP systems, how it is being synchronized, what information is being shared, or not being shared. Most importantly, making sure that the data is mastered. What is the best way to do this? In the recent webcast: Reduce ERP consolidation Risks with Oracle Master Data Management we outlined 3 key guidelines: #1: Consolidate your Product Data#2: Consolidate your Customer, Supplier (Party Data) #3: Consolidate your Financial Data Together these help customers achieve reduced risk, better customer intimacy, reducing inventory levels, elimination of product variations, and finally a single master chart of accounts. In the case of Oracle's customer Zebra Technologies, they were able to consolidate over 140 applications by mastering their data. Ultimately this gave them 60% cost savings for the year on IT spend. Oracle’s Solution for ERP Consolidation: Master Data Management Oracle's enterprise master data management (MDM) can play a big role in ERP consolidation. It includes a set of products that consolidates and maintains complete, accurate, and authoritative master data across the enterprise and distributes this master information to all operational and analytical applications as a shared service. It’s optimized to work with any application source (not just Oracle’s) and can integrate using technology from Oracle Fusion Middleware (i.e. GoldenGate for data synchronization and real-time replication or ODI with its E-LT optimized bulk data and transformation capability). In addition especially for ERP consolidation use cases it’s important to leverage the AIA and SOA capabilities as part of Fusion Middleware to connect these multiple applications together and relay the data into the correct hub. Oracle’s MDM strategy is a unique offering in the industry, one that has common elements across the top and bottom in Middleware, BI/DW, Engineered systems combined with Enterprise Data Quality to enable comprehensive Data Governance at all levels. In addition, Oracle MDM provides the best-in-class capabilities to master all variations of data, including customer, supplier, product, financial data. But ultimately at the center of Oracle MDM is your data, making it more trusted, making it secure and accessible as part of a role-based approach, and getting it to make sense to you in any situation, whether it’s a specific ERP process like we talked about or something that is custom to your organization. To learn more about these techniques in ERP consolidation watch our webcast or goto our Oracle MDM website at www.oracle.com/goto/mdm

• documentFragment.cloneNode(true) doesn't clone jQuery data

  - by taber

  I have a documentFragment with several child nodes containing some .data() added like so: myDocumentFragment = document.createDocumentFragment(); for(...) { myDocumentFragment.appendChild( $('').addClass('button') .attr('href', 'javascript:void(0)') .html('click me') .data('rowData', { 'id': 103, 'test': 'testy' }) .get(0) ); } When I try to append the documentFragment to a div on the page: $('#div').append( myDocumentFragment ); I can access the data just fine: alert( $('#div a:first').data('rowData').id ); // alerts '103' But if I clone the node with cloneNode(true), I can't access the node's data. :( $('#div').append( myDocumentFragment.cloneNode(true) ); ... alert( $('#div a:first').data('rowData').id ); // alerts undefined Has anyone else done this or know of a workaround? I guess I could store the row's data in jQuery.data('#some_random_parent_div', 'rows', [array of ids]), but that kinda defeats the purpose of making the data immediately/easily available to each row. I've also read that jQuery uses documentFragments, but I'm not sure exactly how, or in what methods. Does anyone have any more details there? Thanks!

• XNA - Saving Game Data without TypeWriter?

  - by Zabby

  In the past, I've had some trouble with reading and writing content for XNA. I think I'm firmly set on this tutorial which sets up a four project structure (Game, Content, Library, Pipeline Extension) for the solution that other websites suggest, too. The options it offers for content reading seem great. But problem! This tutorial (and all others I've found) have stated that the Content Pipeline Extension Project is not distributed with the game, which is fine in itself, but this is combined with the fact that any content writing objects are placed in this non-distributable library. The ability to actually write content of an already existing type (save game files, namely) is pretty critical to the project I'm trying to make. I've already learned the hard way you simply can't place the Content Pipeline reference in another project besides the extension for easier access to the intermediate deserializer. Is there another object I can access for writing save game data? Am I actually, despite the warnings of this tutorial, able to use the TypeWriter outside of the Content Pipeline Extension Project? Or is there a third option I am missing here?
