  • How do I automate a backup of new MobileMe calendar data

    - by ridogi
    The new MobileMe iCal data lives in the cloud, and the data on your computer is actually a cache. This support article http://support.apple.com/kb/HT4226 from Apple explains how to backup calendar data by exporting to an .ics file. I would like to automate that process via AppleScript, Automator or any other method (paid software is fine). The sticking point with AppleScript is selecting the calendar on the left hand column. In Automator I don't think the available actions support this level of automation.

  • Chapter 7–Enforced Data Protection

    - by drsql
    As the book progresses, I find myself veering from the original stated outline quite a bit, because as I teach about this more (and I am teaching a daylong db design class in August at http://www.sqlsolstice.com/ … shameless plug, but it is on topic :) I start to find that a given order works better. Originally I had slated myself to talk more about modeling here for three chapters, then get back to the more implementation topics to finish out the book, but now I am going to keep plugging through...(read more)

  • Script to calculate the Median value for SQL Server data

    The standard SQL language has a number of aggregate functions like: SUM, MIN, MAX, AVG, but a common statistics function that SQL Server does not have is a built-in aggregate function for median. The median is the value that falls in the middle of a sorted resultset with equal parts that are smaller and equal parts that are greater. Since there is no built-in implementation for the median, the following is a simple solution I put together to find the median. Get smart with SQL Backup ProPowerful centralised management, encryption and more.SQL Backup Pro was the smartest kid at school. Discover why.

  • multitenancy with some data sharing

    - by user55108
    I'm in the planning stages of a new webapp, and I am leaning strongly toward a multitenancy model. The app has a file storage function, where the user can upload (and operate on) files. I would like the ability of the user to share these files, however. How is this typically accomplished in a multi-tenant model? The example would be something like google docs. Each user has their own files; they can edit and tag and build collections with these files. Then, they can share a doc or a collection with someone else for collaboration. If every user has their own Database and tables, what strategy would one use to allow this kind of sharing while minimizing duplication of files and associated metadata?

  • Javascript storing data

    - by user985482
    Hi I am a beginner web developer and am trying to build the interface of a simple e-commerce site as a personal project.The site has multiple pages with checkboxes.When someone checks an element it retrives the price of the element and stores it in a variable.But when I go to the next page and click on new checkboxes products the variable automaticly resets to its original state.How can I save the value of that variable in Javascript? This is the code I've writen using sessionStorage but it still dosen't work when I move to next page the value is reseted. How can I wright this code so that i dosen't reset on each page change.All pages on my website use the same script. $(document).ready(function(){ var total = 0; $('input.check').click(function(){ if($(this).attr('checked')){ var check = parseInt($(this).parent().children('span').text().substr(1 , 3)); total+=check; sessionStorage.var_name=0 + total; alert(sessionStorage.var_name); }else{ var uncheck = parseInt($(this).parent().children('span').text().substr(1 , 3)); total-=uncheck; } })

  • Manipulating XML Data in SQL Server

    When the average database developer is obliged to manipulate XML, either shredding it into relational format, or creating it from SQL, it is often done 'at arms length'. A shame, since effective use of techniques that go beyond the basics can save much code, "It really helped us isolate where we were experiencing a bottleneck"- John Q Martin, SQL Server DBA.

  • Data Mining Email with Thunderbird

    - by user554629
    Oracle has many formal, searchable locations:  Service Requests, BugIDs, Technical Documents. These contain the results of an investigation for a customer crash situation;  they're created after the intense work of resolution is over, and typically contain the "root cause" of the failure ... but not the methods for identifying that cause. Email is still the standby for interacting with quickly formed groups of specialists, focusing on a particular incident.Customer BI, Network and System specialists;  Oracle Tech Support, Development, Consultants; OEM Database, OS technical support.   It is a chaotic, time-oriented set of configuration, call stacks, changes, techniques to discover and repair the failure. I needed to organize that information into something cohesive to prepare the blog entry on Teradata.  My corporate email client of choice is Thunderbird.   My original (flawed) search technique: R-Click on Inbox in Thunderbird left pane, and choose Search Messages Subject:  [ teradata ] Results: A new window titled "Search Messages"Single pane of selected messagesColumn headings:  Subject  From  Date  LocationNo preview window for messages There are 673 email entries in the result ( too many )  R-click icon just above the vertical scroll bar on the rightCheck [x] Tags Click on the Tags header to sort by "Important" View contents of message by double-clickingOpens in the Thunderbird Main Window in a new Tab Not what I was looking for, close the tab and try again. There has to be a better way.  ( and there is ) I need to be more productive, eliminating duplicate-chained messages, for example.   Even the Tag "Important" that was added during the investigation phase, is "not so much" for my current task. In the "Search Messages" window, click [ Save as Search Folder ] [ teradata ]  Appears as a new folder in my Inbox. Focus on that folder and the results appear with a list of messages like every other folder in the Inbox.Only the results of the search are shown A preview window is now available for each message Sort, Select message, Cursor Down ... navigates quickly through the messages. But wait, there's more ... Click Find ( Ctrl-F) Enter a search term for the message body, like.[ LIBPATH ] The search is "sticky" ... each message you cycle through wil focus ( and highlight) the LIBPATH search term. And still more .... Reset the Tag"Important" message.   Press "1" and the tag is removed Press "4" and a new Tag "ToDo" is applied After applying all of the tags, sort by Tag for a new message order Adjust the search criteria ... R-click on the [ teradata ] search folder, and choose Properties Add additional criteria to narrow the search Some of the information I'm looking for did not contain "teradata" in the subject line. + Body  [ contains ] [ Best Practices ] That's it.  Much more efficient search.   Thank you Thunderbird.

  • RAID setup for maximizing data retention and read speed

    - by cat pants
    My goals are simple: maximize data retention safety, and maximize read speeds. My first instinct is to do a a three drive software RAID 1. I have only used fakeraid RAID 1 in the past and it was terrible (would have led to data loss actually if it weren't for backups) Would you say software raid 1 or a cheap actual hardware raid card? OS will be linux. Could I start with a two drive raid 1 and add a third drive on the fly? Can I hot swap? Can I pull one of the drives and throw it into a new machine and be able to read all the data? I do not want a situation where I have a raid card fail and have to try and find the same chipset in order to read my data (which i am assuming can happen) Please clarify any points on which it sounds like I have no idea what I am talking about, as I am admittedly inexperienced here. (My hardest lesson was fakeraid lol) Thanks!

  • 5 Reasons You Must Start Capturing Baseline Data

    It is widely acknowledged within the SQL Server community that baselines represent valuable information that DBAs should capture. Unfortunately, very few companies manage to log and report on this information, and DBAs are then forced to troubleshoot from the hip and scramble to find evidence to prove that the database is not the problem. This article will make a compelling argument for why DBAs must start capturing baseline information, and will create a roadmap for subsequent posts.

  • glTexImage2D not loading my data

    - by Clyde
    Can anyone suggest why this code doesn't work? When I draw using this texture all I get is black. If I use GLUtils.texImage2D() to load a png file, it works correctly. ByteBuffer bb = ByteBuffer.allocateDirect(128*128*4).order(ByteOrder.nativeOrder()); bb.position(0); for(int row = 0; row != 128; row++) { for(int i = 0 ; i != 128 ; i++) { bb.put((byte)0x80); bb.put((byte)0xFF); bb.put((byte)0xFF); bb.put((byte)i); } } int[] handle = new int[1]; GLES20.glEnable(GLES20.GL_TEXTURE_2D); GLES20.glGenTextures(1, handle, 0); DrawAdapter.checkGlError("Gen textures"); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, handle[0]); DrawAdapter.checkGlError("Bind textures"); bb.position(0); GLES20.glTexImage2D(GLES20.GL_TEXTURE_2D, 0, GLES20.GL_RGBA, 128, 128, 0, GLES20.GL_RGBA, GLES20.GL_UNSIGNED_BYTE, bb); DrawAdapter.checkGlError("glTexImage2D"); return handle[0];

  • Forwarding data between two interfaces

    - by user84471
    I installed Ubuntu server 12.04 after that I installed dhcp3-server and configured it like this: At isc-dhcp-server INTERFACES="eth0" And in dhcpd.conf # A slightly different configuration for an internal subnet. subnet 192.168.1.0 netmask 255.255.255.0 { range 192.168.1.5 192.168.1.100; option domain-name-servers 192.168.1.1; option domain-name "nazwa.local"; option routers 192.168.1.1; option broadcast-address 192.168.1.255; default-lease-time 600; max-lease-time 7200; } Also I have two eth interfaces: # second netowrk interface auto eth0 iface eth0 inet static address 192.168.1.1 netmask 255.255.255.0 # The primary network interface auto eth1 iface eth1 inet dhcp When I plug computer to eth0 I get propertly ip adress but I can't visit any sites. I do even this: echo 1 > /proc/sys/net/ipv4/ip_forward

  • Data structures for a 3D array

    - by Smallbro
    Currently I've been using a 3D array for my tiles in a 2D world but the 3D side comes in when moving down into caves and whatnot. Now this is not memory efficient and I switched over to a 2D array and can now have much larger maps. The only issue I'm having now is that it seems that my tiles cannot occupy the same space as a tile on the same z level. My current structure means that each block has its own z variable. This is what it used to look like: map.blockData[x][y][z] = new Block(); however now it works like this map.blockData[x][y] = new Block(z); I'm not sure why but if I decide to use the same space on say the floor below it wont allow me to. Does anyone have any ideas on how I can add a z-axis to my 2D array? I'm using java but I reckon the concept carries across different languages.

  • How can I perform sentiment analysis on extracted text from online sources?

    - by aniket69
    I'm working on extracting the sentiment from YouTube comments, blogs, news content, Facebook wall posts, and Twitter feeds. I'm looking for an automated way to do this: the two third-party solutions I've found have been AlchemyAPI and RapidMiner. Are these the best way to approach this project, or should I be using something else? Is there a more efficient way to approach sentiment analysis? What techniques have worked for you in a project like this?

  • In need of assistance for recovering a lost partition

    - by Tek
    The program that has worked for the most part is Active@ Partition Recovery. I'm so close but yet so far from recovering my data. Okay so here's what happens. In the following screenshot (blanked out a folder and filename with profanity in case some of you guys are at work :P), it detects the partition I accidentally deleted with ALL 100% of my data listed. Of course, I didn't write ANY data to that drive after I did this. But when I click "recover" and finishes the recovery process, in Windows I click on the partition that was just was just recovered... It's EMPTY. The program seems to be able to see my lost files, but when I recover the partition windows doesn't seem to think the same =( Things I tried: I tried running a chkdsk /r /f after I recovered the partition, apparently it couldn't find any errors. Tried using other software like TestDisk to recover the partition, but they (all) act similar to Windows in that it detects the (missing) partition but when I browse it there's no files. The partition is there along with all the file and data information. The sector information is also in the screenshot, is there any way I can use this to my advantage in recovering my data? Other information: Dualboot: Win8 / Ubuntu 12.10 x64 1TB Internal desktop drive, GPT Layout, NTFS formatted drive, 64K allocation size.

  • Data take on with Drupal 6

    - by Robert MacLean
    We are migrating our current intranet to Drupal 6 and there is a lot of data within the current system which can be classified into: List data, general lists of fields. Common use is phone list of the employees phone numbers. Document repository. Just basically a web version of a file share for documents. I can easily get the data + meta infomation out, but how do I bulk upload the two types of data into Drupal, as uploading the hundred of thousands of items manually is just not acceptable.

  • Algorithm for optimal combination of two variables

    - by AlanChavez
    I'm looking for an algorithm that would be able to determine the optimal combination of two variables, but I'm not sure where to start looking. For example, if I have 10,000 rows in a database and each row contains price, and square feet is there any algorithm out there that will be able to determine what combination of price and sq ft is optimal. I know this is vague, but I assume is along the lines of Fuzzy logic and fuzzy sets, but I'm not sure and I'd like to start digging in the right field to see if I can come up with something that solves my problem.

  • Should I always encapsulate an internal data structure entirely?

    - by Prog
    Please consider this class: class ClassA{ private Thing[] things; // stores data // stuff omitted public Thing[] getThings(){ return things; } } This class exposes the array it uses to store data, to any client code interested. I did this in an app I'm working on. I had a ChordProgression class that stores a sequence of Chords (and does some other things). It had a Chord[] getChords() method that returned the array of chords. When the data structure had to change (from an array to an ArrayList), all client code broke. This made me think - maybe the following approach is better: class ClassA{ private Thing[] things; // stores data // stuff omitted public Thing[] getThing(int index){ return things[index]; } public int getDataSize(){ return things.length; } public void setThing(int index, Thing thing){ things[index] = thing; } } Instead of exposing the data structure itself, all of the operations offered by the data structure are now offered directly by the class enclosing it, using public methods that delegate to the data structure. When the data structure changes, only these methods have to change - but after they do, all client code still works. Note that collections more complex than arrays might require the enclosing class to implement even more than three methods just to access the internal data structure. Is this approach common? What do you think of this? What downsides does it have other? Is it reasonable to have the enclosing class implement at least three public methods just to delegate to the inner data structure?

  • Summarising and Bubbling of KPI data

    - by simonsabin
    Something I’m very conscious of when delivering a  BI solution is being able to show the facts in a concise way but also not to hide whats going on. I was reminded of this when I looked at the weather today. Everywhere they are reporting weather warnings for the south east and so I though I’d check on the BBC website http://news.bbc.co.uk/weather/forecast/4281?area=AL5 Looking at that I thought we are going to miss the worst of it, just like a few weeks ago. However from previous experience...(read more)

  • Storing translation data as JSON column

    - by j0ntech
    We're deciding on how to store translations of some descriptions of database items. We could go the traditional way and keep a translations table (and a language table and an object_translation linking table) OR we thought it might be better to just have a Description column that contains JSON like the following: { "EN": "This is the translation in English", "EE" : "See on kirjeldus eesti keeles" } Are there any serious downsides as to why we shouldn't use this? (I haven't seen it being used anywhere else)
