• Can LINQ expression classes implement the observer pattern instead of deferred execution?

  - by Tormod

  Hi. We have issues within an application using a state machine. The application is implemented as a windows service and is iteration based (it "foreaches" itself through everything) and there are myriads of instances being processed by the state machine. As I'm reading the MEAP version of Jon Skeets book "C# in Depth, 2nd ed", I'm wondering if I can change the whole thing to use linq expression instances so that guards and conditions are represented using expression trees. We are building many applications on this state machine engine and would probably greatly benefit from the new Expression tree visualizer in VS 2010 Now, simple example. If I have an expression tree where there is an OR Expression condition with two sub nodes, is there any way that these can implement the observer pattern so that the expression tree becomes event driven? If a condition change, it should notify its parent node (the OR node). Since the OR node then changes from "false" to "true", then it should notify ITS parent and so on. I love the declarative model of expression trees, but the deferred execution model works in opposite direction of the control flow if you want event based "live" conditions. Am I off on a wild goose chase here? Or is there some concept in the BCL that may help me achieve this?

• checking and replacing a value in an array jquery

  - by liz

  i have a table of data: <table id="disparities" class="datatable"> <thead> <tr> <th scope="col">Events</th> <th scope="col">White</th> <th scope="col">Black</th> <th scope="col">Hispanic</th><th scope="col">Asian/Pacific Islands</th> </tr> </thead> <tbody> <tr> <th scope="row">Hospitalizations</th> <td>0.00</td> <td>20</td> <td>10</td> <td>5</td> </tr> <tr> <th scope="row">ED Visits</th> <td>19</td> <td>90</td> <td>40</td> <td>18</td> </tr> </tbody> </table> i have a function that retrieves the values from the above table into an array like so (0.00,19) var points1 = $('#disparities td:nth-child(2)').map(function() { return $(this).text().match(/\S+/)[0]; }).get(); i want to check if there is a 0.00 value (or it could be just 0) and change that value to NA... so my resulting array is then (NA,19) not really sure how to go about this, whether in the initial match or as a separate action...

• Whatfor Visual Studio?! ml, cl, and link exe-cutables would suffice

  - by AntonIO

  It says in /library article /9s7c9wdw : "You can start this tool [cl.exe] only from the Visual Studio command prompt. You cannot start it from a system command prompt or from Windows Explorer." The corresponding (v=VS.80) page geared towards Visual Studio 2005 makes no such mention. Moreover, there is this Q&A. Thing is: Why should anybody spend anything on VS? ml is provided free of charge- necessarily so since it poses no value addition. The combined size of the other two is 895kb. Uncompressed. The GUI is a disservice. I myself have found half a dozen bugs. However, if the above is true, you'd need the IDE. MSFT fanboys, please step up. Background is that I have the 2008 Pro ed. The official Firefox builds use VS 2005 which I have on another system. To me no redundancy is acceptable. That's when I started pondering about boiling down VS and merely copying over the essential binaries. Then extended the thought to synthetically updating V$.

• git-svn: reset tracking for master

  - by digitala

  I'm using git-svn to work with an SVN repository. My working copies have been created using git svn clone -s http://foo.bar/myproject so that my working copy follows the default directory scheme for SVN (trunk, tags, branches). Recently I've been working on a branch which was created using git-svn branch myremotebranch and checked-out using git checkout --track -b mybranch myremotebranch. I needed to work from multiple locations, so from the branch I git-svn dcommit-ed files to the SVN repository quite regularly. After finishing my changes, I switched back to the master and executed a merge, committed the merge, and tried to dcommit the successful merge to the remote trunk. It seems as though after the merge the remote tracking for the master has switched to the branch I was working on: # git checkout master # git merge mybranch ... (successful) # git add . # git commit -m '...' # git svn dcommit Committing to http://foo.bar/myproject/branches/myremotebranch ... # Is there a way I can update the master so that it's following remotes/trunk as before the merge? I'm using git 1.7.0.5, if that's any help.

• How to optimize Conway's game of life for CUDA?

  - by nlight

  I've written this CUDA kernel for Conway's game of life: global void gameOfLife(float* returnBuffer, int width, int height) { unsigned int x = blockIdx.x*blockDim.x + threadIdx.x; unsigned int y = blockIdx.y*blockDim.y + threadIdx.y; float p = tex2D(inputTex, x, y); float neighbors = 0; neighbors += tex2D(inputTex, x+1, y); neighbors += tex2D(inputTex, x-1, y); neighbors += tex2D(inputTex, x, y+1); neighbors += tex2D(inputTex, x, y-1); neighbors += tex2D(inputTex, x+1, y+1); neighbors += tex2D(inputTex, x-1, y-1); neighbors += tex2D(inputTex, x-1, y+1); neighbors += tex2D(inputTex, x+1, y-1); __syncthreads(); float final = 0; if(neighbors < 2) final = 0; else if(neighbors 3) final = 0; else if(p != 0) final = 1; else if(neighbors == 3) final = 1; __syncthreads(); returnBuffer[x + y*width] = final; } I am looking for errors/optimizations. Parallel programming is quite new to me and I am not sure if I get how to do it right. The rest of the app is: Memcpy input array to a 2d texture inputTex stored in a CUDA array. Output is memcpy-ed from global memory to host and then dealt with. As you can see a thread deals with a single pixel. I am unsure if that is the fastest way as some sources suggest doing a row or more per thread. If I understand correctly NVidia themselves say that the more threads, the better. I would love advice on this on someone with practical experience.

• Socket Read In Multi-Threaded Application Returns Zero Bytes or EINTR (-1)

  - by user309670

  Hi. Am a c-coder for a while now - neither a newbie nor an expert. Now, I have a certain daemoned application in C on a PPC Linux. I use PHP's socket_connect as a client to connect to this service locally. The server uses epoll for concurrent connections via a Unix socket. A user submitted string is parsed for certain characters/words using strstr() and if found, spawns 4 joinable threads to different websites simultaneously. I use socket, connect, write and read, to interact with the said webservers via TCP on port 80 in each thread. All connections and writes seems successful. Reads to the webserver sockets fail however, with either (A) all 3 threads seem to hang, and only one thread returns -1 and errno is set to 104. The responding thread takes like 10 minutes - an eternity long:-(. *I read somewhere that the 104 (is EINTR) suggests that ...'the connection was reset by peer', or (B) 0 bytes from 3 threads, and only 1 of the 4 threads actually returns some data. Isn't the socket read/write thread-safe? Otherwise, use thread-safe (and reentrant) libc functions such as strtok_r, gethostbyname_r, etc. *I doubt that the said webhosts are actually resetting the connection, because when I run a single-threaded standalone (everything else equal) all things works perfectly right. There's a second problem too (oops), I can't write back to the client who connect to my epoll-ed Unix socket. My daemon application will hang and hog CPU 100% for ever. Yet nothing is written to the clients end. Am sure the client (a very typical PHP socket application) hasn't closed the connection whenever this is happening - no error(s) detected either. I cannot figure-out whatever is wrong even with Valgrind or GDB

• Programming an IPTV application- Client/Server

  - by Sumit Ghosh

  I am part of a team which has been given a task to deploy an IPTV solution for a company. The system has been architect-ed like this. There is Video capture card , which receives satellite signals from a satellite receiver. This video capture card is part of a windows 7 machine. The signals need to be trans coded here and passed to a streaming server which will be received by end users. The end users will be desktop users having a C#.NET application installed to view the channels. I am confused at the choice of server software as I have multiple choices - Windows Media Server, VideoLan (VLC project), or Flash Media Server, it also supports MPEG-2 HD. My main aim to be able to stream MPEG-2 channels with HD quality and encrypt the channels at the server end so that the streams can be protected. I know reversing is possible but it wont be easy as for every naive user with wireshark snooping my streams. If any of you here has ever done such an implementation please do suggest me the best technologies I should go for. Iam open to C#,C++ and other similar languages. Any help shall be deeply appreciated. edit: End Users shall be part of Internet and not necessarily a lan, reason for this question is internet doesn't support multicast like Lan, so I need some suggestions.

• What happens to class members when malloc is used instead of new?

  - by Felix

  I'm studying for a final exam and I stumbled upon a curious question that was part of the exam our teacher gave last year to some poor souls. The question goes something like this: Is the following program correct, or not? If it is, write down what the program outputs. If it's not, write down why. The program: #include<iostream.h> class cls { int x; public: cls() { x=23; } int get_x(){ return x; } }; int main() { cls *p1, *p2; p1=new cls; p2=(cls*)malloc(sizeof(cls)); int x=p1->get_x()+p2->get_x(); cout<<x; return 0; } My first instinct was to answer with "the program is not correct, as new should be used instead of malloc". However, after compiling the program and seeing it output 23 I realize that that answer might not be correct. The problem is that I was expecting p2->get_x() to return some arbitrary number (whatever happened to be in that spot of the memory when malloc was called). However, it returned 0. I'm not sure whether this is a coincidence or if class members are initialized with 0 when it is malloc-ed. Is this behavior (p2->x being 0 after malloc) the default? Should I have expected this? What would your answer to my teacher's question be? (besides forgetting to #include <stdlib.h> for malloc :P)

• Java - Reading a csv file line by line - stuck with weird non-existent characters being read!

  - by rockit

  hello fellow java developers. I'm having a very strange issue. I'm trying to read a csv file line by line. Im at the point where Im just testing out the reading of the lines. ONly each time that I read a line, the line contains square characters between each character of text. I even saved the file as a txt file in wordpad and notepad with no change. Thus I must be doing something stupid... I have a csv file, standard csv file, yes a text file with commas in it. I try to read a line of text, but the text is all f-ed up and cannot find the phrase within the text. Any advice? code below. //open csv File filReadMe = new File(strRoot + "data2.csv"); BufferedReader brReadMe = new BufferedReader(new InputStreamReader(new FileInputStream(filReadMe))); String strLine = brReadMe.readLine(); //for all lines while (strLine != null){ //if line contains "(see also" if (strLine.toLowerCase().contains("(see also")){ //write line from "(see also" to ")" int iBegin = strLine.toLowerCase().indexOf("(see also"); String strTemp = strLine.substring(iBegin); int iLittleEnd = strTemp.indexOf(")"); System.out.println(strLine.substring(iBegin, iBegin + iLittleEnd)); } //update line strLine = brReadMe.readLine(); } //end for brReadMe.close();

• java.net.BindException How can I clear the sockets or what ever is causing it?

  - by user2266067

  I need some help with, I guess a simple networking related problem I'm having. It will also help me better understand how all this works by knowing what isn't being .close()'ed. I'm sure this is pretty simple, but for me its all very new. This is the client program. I can most likely append the server then, if I can figure this out. Thanks public class Server { public static void main(String[] args) { start(); } static int start = 0; public static void start() { try { ServerSocket serverSocket = new ServerSocket(4567); Socket socket = serverSocket.accept(); //1) Take and echo input (In this case a message) BufferedReader bf = new BufferedReader(new InputStreamReader(socket.getInputStream())); String message = bf.readLine(); System.out.println("Message recieved from Client:" + message); //2) Response of client message PrintWriter printWriter = new PrintWriter(socket.getOutputStream(), true); printWriter.println("Server echoing back the message ' " + message + " ' from Client"); } catch (IOException e) { System.out.println("e " + e); System.exit(-1); } start++; clearUp(); if (start < 5) { System.out.println("Closing binds and Restarting" + start); start(); } } public void clearUp(){ //How would I clear the stuff that is left bound so I can restart via start() and avoid the java.net.BindException: Address already in use: JVM_Bind ? } } How would I clear the stuff that is left bound so I can restart via start() and avoid java.net.BindException: Address already in use: JVM_Bind ?

• Run Reporting Service in local mode and generate columns automatically?

  - by grady

  Hi, I have a SQL query right now which I want to use with the MS reporting services in my ASP.NET application. So I created a report in local mode (rdlc) and attached this to a report viewer. Since my query uses parameters, I created a stored procedure, which had exactly those parameters. In addition to that I had some textboxes which are used for entering the params for the query and a button to call the stored proc and to fill the datatset which is bound to the report viewer. This works, I press the button and according to what I entred the correct data is shown. Now my question: In the future I plan to have multiple reports (which will be selected in a dropdown) and I wonder if I can somehow just call the correct stored procedure and according to the columns which are *SELECT*ed in the procedure, the columns are shown in the report. Example: I select report1 from the dropdown (procedure for report 1 is called), 5 columns are shown in the reportviewer. I select report2 from dropdown (procedure for report 2 is called), 8 columns are shown. Is that possible somehow? Thanks :-)

• Merging two arrays in PHP

  - by Industrial

  Hi everyone, I am trying to create a new array from two current arrays. Tried array_merge, but it will not give me what I want. $array1 is a list of keys that I pass to a function. $array2 holds the results from that function, but doesn't contain any non-available resuls for keys. So, I want to make sure that all requested keys comes out with 'null':ed values, as according to the shown $result array. It goes a little something like this: $array1 = array('item1', 'item2', 'item3', 'item4'); $array2 = array( 'item1' => 'value1', 'item2' => 'value2', 'item3' => 'value3' ); Here's the result I want: $result = array( 'item1' => 'value1', 'item2' => 'value2', 'item3' => 'value3', 'item4' => '' ); It can be done this way, but I don't think that it's a good solution - I really don't like to take the easy way out and suppress PHP errors by adding @:s in the code. This sample would obviously throw errors since 'item4' is not in $array2, based on the example. foreach ($keys as $k => $v){ @$array[$v] = $items[$v]; } So, what's the fastest (performance-wise) way to accomplish the same result?

• Sequence Point and Evaluation Order( Preincrement)

  - by Josh

  There was a debate today among some of my colleagues and I wanted to clarify it. It is about the evaluation order and the sequence point in an expression. It is clearly stated in the standard that C/C++ does not have a left-to-right evaluation in an expression unlike languages like Java which is guaranteed to have a sequencial left-to-right order. So, in the below expression, the evaluation of the leftmost operand(B) in the binary operation is sequenced before the evaluation of the rightmost operand(C): A = B B_OP C The following expression according, to CPPReference under the subsection Sequenced-before rules(Undefined Behaviour) and Bjarne's TCPPL 3rd ed, is an UB x = x++ + 1; It could be interpreted as the compilers like BUT the expression below is said to be clearly a well defined behaviour in C++11 x = ++x + 1; So, if the above expression is well defined, what is the "fate" of this? array[x] = ++x; It seems the evaluation of a post-increment and post-decrement is not defined but the pre-increment and the pre-decrement is defined. NOTE: This is not used in a real-life code. Clang 3.4 and GCC 4.8 clearly warns about both the pre- and post-increment sequence point.

• Swing Menu dimensions

  - by ikurtz

  Greetings. I am trying to learn Java and Swing (today is my first day). I have been able to set up a menu in my test application. but the items occupy very little space (they are narrow). How do I go about extendng the amount of space it uses? I am studying Teach Yourself Java 6 in 21 Days 5th Ed, Java Swing, 2nd Edition, 2002 and Teach Yourself Programming With Java In 24 Hours, 4th Edition (2005) but none of them shed any light on this issue. EDIT: Menu code: JMenu _Game = new JMenu("Game"); JMenuItem _New = new JMenuItem("New"); JMenuItem _Exit = new JMenuItem("Exit"); JMenu _Turn = new JMenu("Turn"); JMenuItem _Red = new JMenuItem("Red"); JMenuItem _Yellow = new JMenuItem("Yellow"); _Turn.add(_Red); _Turn.add(_Yellow); _Game.add(_New); _Game.addSeparator(); _Game.add(_Turn); _Game.addSeparator(); _Game.add(_Exit); JMenu _Help = new JMenu("Help"); JMenuItem _About = new JMenuItem("About"); _Help.add(_About); JMenuBar _MenuBar = new JMenuBar(); _MenuBar.add(_Game); _MenuBar.add(_Help); setJMenuBar(_MenuBar); EDIT: Solved! JMenuItem _New = new JMenuItem("New "); just add spaces as needed! simple.

• Misaligned Pointer Performance

  - by Elite Mx

  Aren't misaligned pointers (in the BEST possible case) supposed to slow down performance and in the worst case crash your program (assuming the compiler was nice enough to compile your invalid c program). Well, the following code doesn't seem to have any performance differences between the aligned and misaligned versions. Why is that? /* brutality.c */ #ifdef BRUTALITY xs = (unsigned long *) ((unsigned char *) xs + 1); #endif ... /* main.c */ #include <stdio.h> #include <stdlib.h> #define size_t_max ((size_t)-1) #define max_count(var) (size_t_max / (sizeof var)) int main(int argc, char *argv[]) { unsigned long sum, *xs, *itr, *xs_end; size_t element_count = max_count(*xs) >> 4; xs = malloc(element_count * (sizeof *xs)); if(!xs) exit(1); xs_end = xs + element_count - 1; sum = 0; for(itr = xs; itr < xs_end; itr++) *itr = 0; #include "brutality.c" itr = xs; while(itr < xs_end) sum += *itr++; printf("%lu\n", sum); /* we could free the malloc-ed memory here */ /* but we are almost done */ exit(0); } Compiled and tested on two separate machines using gcc -pedantic -Wall -O0 -std=c99 main.c for i in {0..9}; do time ./a.out; done

• Finding k elements of length-n list that sum to less than t in O(nlogk) time

  - by tresbot

  This is from Programming Pearls ed. 2, Column 2, Problem 8: Given a set of n real numbers, a real number t, and an integer k, how quickly can you determine whether there exists a k-element subset of the set that sums to at most t? One easy solution is to sort and sum the first k elements, which is our best hope to find such a sum. However, in the solutions section Bentley alludes to a solution that takes nlog(k) time, though he gives no hints for how to find it. I've been struggling with this; one thought I had was to go through the list and add all the elements less than t/k (in O(n) time); say there are m1 < k such elements, and they sum to s1 < t. Then we are left needing k - m1 elements, so we can scan through the list again in O(n) time looking for all elements less than (t - s1)/(k - m1). Add in again, to get s2 and m2, then again if m2 < k, look for all elements less than (t - s2)/(k - m2). So: def kSubsetSumUnderT(inList, k, t): outList = [] s = 0 m = 0 while len(outList) < k: toJoin = [i for i in inList where i < (t - s)/(k - m)] if len(toJoin): if len(toJoin) >= k - m: toJoin.sort() if(s0 + sum(toJoin[0:(k - m - 1)]) < t: return True return False outList = outList + toJoin s += sum(toJoin) m += len(toJoin) else: return False My intuition is that this might be the O(nlog(k)) algorithm, but I am having a hard time proving it to myself. Thoughts?

• Boot From a USB Drive Even if your BIOS Won’t Let You

  - by Trevor Bekolay

  You’ve always got a trusty bootable USB flash drive with you to solve computer problems, but what if a PC’s BIOS won’t let you boot from USB? We’ll show you how to make a CD or floppy disk that will let you boot from your USB drive. This boot menu, like many created before USB drives became cheap and commonplace, does not include an option to boot from a USB drive. A piece of freeware called PLoP Boot Manager solves this problem, offering an image that can burned to a CD or put on a floppy disk, and enables you to boot to a variety of devices, including USB drives. Put PLoP on a CD PLoP comes as a zip file, which includes a variety of files. To put PLoP on a CD, you will need either plpbt.iso or plpbtnoemul.iso from that zip file. Either disc image should work on most computers, though if in doubt plpbtnoemul.iso should work “everywhere,” according to the readme included with PLoP Boot Manager. Burn plpbtnoemul.iso or plpbt.iso to a CD and then skip to the “booting PLoP Boot Manager” section. Put PLoP on a Floppy Disk If your computer is old enough to still have a floppy drive, then you will need to put the contents of the plpbt.img image file found in PLoP’s zip file on a floppy disk. To do this, we’ll use a freeware utility called RawWrite for Windows. We aren’t fortunate enough to have a floppy drive installed, but if you do it should be listed in the Floppy drive drop-down box. Select your floppy drive, then click on the “…” button and browse to plpbt.img. Press the Write button to write PLoP boot manager to your floppy disk. Booting PLoP Boot Manager To boot PLoP, you will need to have your CD or floppy drive boot with higher precedence than your hard drive. In many cases, especially with floppy disks, this is done by default. If the CD or floppy drive is not set to boot first, then you will need to access your BIOS’s boot menu, or the setup menu. The exact steps to do this vary depending on your BIOS – to get a detailed description of the process, search for your motherboard’s manual (or your laptop’s manual if you’re working with a laptop). In general, however, as the computer boots up, some important keyboard strokes are noted somewhere prominent on the screen. In our case, they are at the bottom of the screen. Press Escape to bring up the Boot Menu. Previously, we burned a CD with PLoP Boot Manager on it, so we will select the CD-ROM Drive option and hit Enter. If your BIOS does not have a Boot Menu, then you will need to access the Setup menu and change the boot order to give the floppy disk or CD-ROM Drive higher precedence than the hard drive. Usually this setting is found in the “Boot” or “Advanced” section of the Setup menu. If done correctly, PLoP Boot Manager will load up, giving a number of boot options. Highlight USB and press Enter. PLoP begins loading from the USB drive. Despite our BIOS not having the option, we’re now booting using the USB drive, which in our case holds an Ubuntu Live CD! This is a pretty geeky way to get your PC to boot from a USB…provided your computer still has a floppy drive. Of course if your BIOS won’t boot from a USB it probably has one…or you really need to update it.

• The Beginner’s Guide to Greasemonkey User Scripts in Firefox

  - by Asian Angel

  Everybody knows that Firefox has add-ons for virtually everything, but if you don’t want to bloat your installation you’ve always got the option of Greasemonkey scripts instead. Here’s a quick primer on how to use them. Getting Started with User Scripts Once you have Greasemonkey installed, managing the extension is really easy. Left click on the status bar icon to turn the extension on/off and right click to access the context menu shown here. Whether you use the Options button in the Add-ons Manager Window or the context menu shown above, both will bring up the Manage User Scripts dialog. At the moment you have a nice clean slate to work with… time to get some scripts added in. The majority of user scripts can be found at two different sites, the first being appropriately named userscripts.org, and you can either browse by tag or search for a script. As you can see here your search for a particular type of script can be quickly narrowed down based on category. There is definitely a lot to choose from. For our example we focused on the “textarea” tag. There were 62 scripts available but we quickly found what we were looking for on the first page. Installing, Managing, & Using Your Scripts When you find a script that you want to install visit the script’s homepage and click on the “Install” button. Note: Link for this script provided below.

• SQL SERVER – A Picture is Worth a Thousand Words – A Collection of Inspiring and Funny Posts by Vinod Kumar

  - by pinaldave

  One of the most popular quotes is: A picture is worth a thousand words. Working on this concept I started a series over my blog called the “Picture Post”. Rather than rambling over tons of material over text, we are trying to give you a capsule mode of the blog in a quick glance. Some of the picture posts already available over my blog are: Correlation of Ego and Work: Ego and Pride most of the times become a hindrance when we work inside a team. Take this cue, the first ever Picture post was published. Simple and easy to understand concept. Would want to say, Ego is the biggest enemy to humans. Read Original Post. Success (Perception Vs Reality): Personally, have always thought success is not something the talented achieve with the opportunity presented to them, but success is developed using the opportunity in hand now. In this fast paced world where success is pre-defined and convoluted by metrics it is hard to understand how complex it can sometimes be. So I took a stab at this concept in a simple way. Read Original Post. Doing Vs Saying: As Einstein would describe, Insanity is doing the same thing over and over again and expecting different results. Given the amount of information we get, it is difficult to keep track, learn and implement the same. If you were ever reminded of your college days, there will always be 5-6 people doing different things and we naturally try to emulate what they are doing. This could be from competitive exams GMAT, GRE, CAT, Higher-Ed, B-School hunting etc. Rather than saying you are going to do, it is best to do and then say!!! Read Original Picture Post. Your View Vs Management View: Being in the corporate world can be really demanding and we keep asking this question – “Why me?” when the performance appraisal process ends. In this post I just want to ask you one frank opinion – “Are you really self-critical in your assessments?”. If that is the case there shouldn’t be any heartburns or surprises. If you had just one thing to take back, well forget what others are getting but invest time in making yourself better because that is going to take you longer and further in your career. Read Picture Post. Blogging lifecycle for majority: I am happy and fortunate to be in this blog post because this picture post surely doesn’t apply to SQLAuthority where consistency and persistence have been the hallmark of the blog. For the majority others, who have a tendency to start a blog, get into slumber for a while and write saying they want to get back to blogging, the picture post was specifically done for them. Paradox of being someone else: It is always a dream that we want to become somebody and in this process of doing so, we become nobody. In this constant tussle of lost identity we forget to enjoy the moment that is in front of us. I just depicted this using a simple analogy of our constant struggle to get to the other side, just to realize we missed the wonderful moments. Grass is not greener on the other side, but grass is greener where we water the surface. Read Picture Post. And on the lighter side… Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: About Me, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology

• Fast Data: Go Big. Go Fast.

  - by Dain C. Hansen

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 For those of you who may have missed it, today’s second full day of Oracle OpenWorld 2012 started with a rumpus. Joe Tucci, from EMC outlined the human face of big data with real examples of how big data is transforming our world. And no not the usual tried-and-true weblog examples, but real stories about taxi cab drivers in Singapore using big data to better optimize their routes as well as folks just trying to get a better hair cut. Next we heard from Thomas Kurian who talked at length about the important platform characteristics of Oracle’s Cloud and more specifically Oracle’s expanded Cloud Services portfolio. Especially interesting to our integration customers are the messaging support for Oracle’s Cloud applications. What this means is that now Oracle’s Cloud applications have a lightweight integration fabric that on-premise applications can communicate to it via REST-APIs using Oracle SOA Suite. It’s an important element to our strategy at Oracle that supports this idea that whether your requirements are for private or public, Oracle has a solution in the Cloud for all of your applications and we give you more deployment choice than any vendor. If this wasn’t enough to get the juices flowing, later that morning we heard from Hasan Rizvi who outlined in his Fusion Middleware session the four most important enterprise imperatives: Social, Mobile, Cloud, and a brand new one: Fast Data. Today, Rizvi made an important step in the definition of this term to explain that he believes it’s a convergence of four essential technology elements: Event Processing for event filtering, business rules – with Oracle Event Processing Data Transformation and Loading - with Oracle Data Integrator Real-time replication and integration – with Oracle GoldenGate Analytics and data discovery – with Oracle Business Intelligence Each of these four elements can be considered (and architect-ed) together on a single integrated platform that can help customers integrate any type of data (structured, semi-structured) leveraging new styles of big data technologies (MapReduce, HDFS, Hive, NoSQL) to process more volume and variety of data at a faster velocity with greater results.  Fast data processing (and especially real-time) has always been our credo at Oracle with each one of these products in Fusion Middleware. For example, Oracle GoldenGate continues to be made even faster with the recent 11g R2 Release of Oracle GoldenGate which gives us some even greater optimization to Oracle Database with Integrated Capture, as well as some new heterogeneity capabilities. With Oracle Data Integrator with Big Data Connectors, we’re seeing much improved performance by running MapReduce transformations natively on Hadoop systems. And with Oracle Event Processing we’re seeing some remarkable performance with customers like NTT Docomo. Check out their upcoming session at Oracle OpenWorld on Wednesday to hear more how this customer is using Event processing and Big Data together. If you missed any of these sessions and keynotes, not to worry. There's on-demand versions available on the Oracle OpenWorld website. You can also checkout our upcoming webcast where we will outline some of these new breakthroughs in Data Integration technologies for Big Data, Cloud, and Real-time in more details. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";}

• GRUB 2 problem after Mac OS X update

  - by vallllll

  I have a MacBook Pro in dual boot Mac OS X / Ubuntu 12.04 (Precise Pangolin). When I boot it I have a rEFIt menu, and I can chose between Mac OS X and Linux. A few days ago I have updated Mac OS X from 10.7 (Lion) to 10.8 (Mountain Lion) using a .dmg image provided by my company. Since then when I select Linux in rEFIt it says: No bootable device --insert boot disk and press any key I have tried going to rEFIt partitioning tool. This is what I got: As suggested in Mac OSX Mavericks update rEFIT broken I wanted to fix the issue the same way as AndrewM, but I don't have the option "MBR table must be updated". Then I booted on Ubuntu 12.04 CD, chose repair broken system, chose root patition /dev/sda6 as this is where my Ubuntu file system is. I got a shell, but I don't really know how to repair the poblem since if it was just Windows dual boot. A GRUB update would solve the issue, but here I don't know where the GRUB 2 is installed. Here are results from Parted, and it is a bit confusing for me as the Mac partition is the one with boot: As you can see the entry 1 is an EFI system partition and is the boot partition, so I wonder if I should install GRUB there or in sda6, which is the Ubuntu filesystem. I am not sure should I work on rEFIt shell or Ubuntu. Unfortunately, I don't remember where GRUB was before update. UPDATE: using same link above I have tried RoundSparrow hilltx answer and installed rEFInd, but the result is same.... still no bootable device when I select Linux. UPDATE 2: just used alternate CD again, mounted on /dev/sda6 and the ran update-grub. It seemed to wok and started listing all my kernels. But after rebooting several times still no bootable device when I select Linux in rEFInd. UDATE 3: Have tried to boot from Ubuntu cd and select "boot from first available filesystem. I got error and dropped to grub rescue shell. I even followed the indications on this link but was unable to boot as I tried to use sdb6 but no luck UPDATE 4 as per Rob Smith request here is out put from ls -l $(find /EFI -iname "*.efi") *MACOSX -rw-r--r--@ 1 root admin 55048 29 oct 17:44 /EFI/refind/drivers_x64/btrfs_x64.efi -rw-r--r--@ 1 root admin 38888 29 oct 17:44 /EFI/refind/drivers_x64/ext2_x64.efi -rw-r--r--@ 1 root admin 39304 29 oct 17:44 /EFI/refind/drivers_x64/ext4_x64.efi -rw-r--r--@ 1 root admin 43432 29 oct 17:44 /EFI/refind/drivers_x64/hfs_x64.efi -rw-r--r--@ 1 root admin 38984 29 oct 17:44 /EFI/refind/drivers_x64/iso9660_x64.efi -rw-r--r--@ 1 root admin 43656 29 oct 17:44 /EFI/refind/drivers_x64/reiserfs_x64.efi -rw-r--r--@ 1 root admin 175016 29 oct 17:44 /EFI/refind/refind_x64.efi -rw-rw-r-- 1 root admin 73232 7 mar 2010 /EFI/tools/dbounce.efi -rw-rw-r-- 1 root admin 763248 7 mar 2010 /EFI/tools/dhclient.efi -rw-rw-r-- 1 root admin 67024 7 mar 2010 /EFI/tools/drawbox.efi -rw-rw-r-- 1 root admin 71312 7 mar 2010 /EFI/tools/dumpfv.efi -rw-rw-r-- 1 root admin 84848 7 mar 2010 /EFI/tools/dumpprot.efi -rw-rw-r-- 1 root admin 472912 7 mar 2010 /EFI/tools/ed.efi -rw-rw-r-- 1 root admin 143856 7 mar 2010 /EFI/tools/edit.efi -rw-rw-r-- 1 root admin 1801008 7 mar 2010 /EFI/tools/ftp.efi -rw-r--r--@ 1 root admin 47848 29 oct 17:44 /EFI/tools/gptsync_x64.efi -rw-rw-r-- 1 root admin 320560 7 mar 2010 /EFI/tools/hexdump.efi -rw-rw-r-- 1 root admin 286384 7 mar 2010 /EFI/tools/hostname.efi -rw-rw-r-- 1 root admin 534416 7 mar 2010 /EFI/tools/ifconfig.efi -rw-rw-r-- 1 root admin 395344 7 mar 2010 /EFI/tools/loadarg.efi -rw-rw-r-- 1 root admin 587408 7 mar 2010 /EFI/tools/ping.efi -rw-rw-r-- 1 root admin 730416 7 mar 2010 /EFI/tools/pppd.efi -rw-rw-r-- 1 root admin 561360 7 mar 2010 /EFI/tools/route.efi -rw-rw-r-- 1 root admin 1961712 7 mar 2010 /EFI/tools/shell.efi -rw-rw-r-- 1 root admin 750224 7 mar 2010 /EFI/tools/tcpipv4.efi -rw-rw-r-- 1 root admin 4048 7 mar 2010 /EFI/tools/textmode.efi -rw-rw-r-- 1 root admin 320656 7 mar 2010 /EFI/tools/which.efi *LINUX

• The EXECUTE permission was denied on the object 'bam_Metadata_GetConfigurationXml'

  We were seeing this exception on two servers when we tried to access the BAM Portal... after having to reconfigure the BAM Portal and Tools for reasons unrelated to the error: --- Log Name:      Application Source:        Bam Web Service Date:          2/18/2011 10:24:07 AM Event ID:      1534 Task Category: None Level:         Error Keywords:      Classic User:          N/A Computer:      yyyyyyyyyyyyyyyyyyyy Description: Current User: yy\yyyyyyyy EXCEPTION: Microsoft.BizTalk.Bam.Management.BamManagerException: Encountered error while executing command on SQL Server "yyyyyyyyyyyyyyy". ---> System.Data.SqlClient.SqlException: The EXECUTE permission was denied on the object 'bam_Metadata_GetConfigurationXml', database 'BAMPrimaryImport', schema 'dbo'.    at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)    at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)    at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)    at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj)    at System.Data.SqlClient.SqlDataReader.ConsumeMetaData()    at System.Data.SqlClient.SqlDataReader.get_MetaData()    at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString)    at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async)    at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result)    at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method)    at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method)    at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior)    at Microsoft.BizTalk.Bam.Management.SqlHelper.ExecuteQuery(String cmdText, CommandType cmdType, Transaction transaction)    --- End of inner exception stack trace ---    at Microsoft.BizTalk.Bam.Management.SqlHelper.ExecuteQuery(String cmdText, CommandType cmdType, Transaction transaction)    at Microsoft.BizTalk.Bam.Management.BamConfigurationManager.GetConfigurationXmlFromPrimaryImportDb()    at Microsoft.BizTalk.Bam.Management.BamConfigurationManager..ctor(String piServer, String piDatabase, Int32 sqlHelperCmdTimeout, Boolean validateServerNames)    at Microsoft.BizTalk.Bam.Management.BamManager..ctor(String primaryImportServer, String primaryImportDatabase, Int32 sqlCmdTimeout, Boolean validateServerNames)    at Microsoft.BizTalk.Bam.Management.BamManager..ctor(String primaryImportServer, String primaryImportDatabase)    at Microsoft.BizTalk.Bam.WebServices.Utilities.FetchBamManager()    at Microsoft.BizTalk.Bam.WebServices.Management.BamManagementService.GetViewSummaryForCurrentUser() EXCEPTION: Microsoft.BizTalk.Bam.Management.BamManagerException: Encountered error while executing command on SQL Server "yyyyyyyyyyyyyyyyyy". ---&gt;

• How to Use Sparklines in Excel 2010

  - by DigitalGeekery

  One of the cool features of Excel 2010 is the addition of Sparklines. A Sparkline is basically a little chart displayed in a cell representing your selected data set that allows you to quickly and easily spot trends at a glance. Inserting Sparklines on your Spreadsheet You will find the Sparklines group located on the Insert tab.   Select the cell or cells where you wish to display your Sparklines. Select the type of Sparkline you’d like to add to your spreadsheet. You’ll notice there are three types of Sparklines, Line, Column, and Win/Loss. We’ll select Line for our example. A Create Sparklines pops up and will prompt you to enter a Data Range you are using to create the Sparklines. You’ll notice that the location range (the range where the Sparklines will appear) is already filled in. You can type in the data range manually, or click and drag with your mouse across to select the data range. This will auto-fill the data range for you. Click OK when you are finished.   You will see your Sparklines appear in the desired cells.   Customizing Sparklines Select the one of more of the Sparklines to reveal the Design tab. You can display certain value points like high and low points, negative points, and first and last points by selecting the corresponding options from the Show group. You can also mark all value points by selecting  Markers. Select your desired Sparklines and click one of the included styles from the Style group on the Design tab. Click the down arrow on the lower right corner of the box to display additional pre-defined styles…   or select Sparkline Color or Marker Color options to fully customize your Sparklines. The Axis options allow additional options such as Date Axis Type, Plotting Data Left to Right, and displaying an axis point to represent the zero line in your data with Show Axis. Column Sparklines Column Sparklines display your data in individual columns as opposed to the Line view we’ve been using for our examples. Win/Loss Sparklines Win/Loss shows a basic positive or negative representation of your data set.   You can easily switch between different Sparkline types by simply selecting the current cells (individually or the entire group), and then clicking the desired type on the Design tab. For those that may be more visually oriented, Sparklines can be a wonderful addition to any spreadsheet. Are you just getting started with Office 2010? Check out some of our other great Excel posts such as how to copy worksheets, print only selected areas of a spreadsheet, and how to share data with Excel in Office 2010.

• 2014 Conferences - JFokus, JavaLand & GeeCon!

  - by Heather VanCura

  There has been a delay in publishing these past event summaries from early 2014--JFokus in February, JavaLand in March, and GeeCon in May. As we plan for Devoxx UK next week, I found these summaries that did not make it past 'draft' stage.  We had some great successes with the first three events of 2014, a Java developer conference trifecta! Participation topics included Java, the JCP program overall and the Adopt-a-JSR programs.   First up in February was JFokus in Stockholm. The energy and talent in Stockholm is amazing and the conference organizers do a stellar job running it and welcoming the speakers of this event.  I enjoyed the city walk and speaker dinner, as well as many opportunities to interact with conference speakers and attendees, both during and after the conference hours. Reza Rehman invited me to speak during his Java EE 7 lab session about the Adopt-a-JSR program, and I gave a quickie session on the JCP and Adopt-a-JSR.  There was also a late night Birds of a Feather (BoF) session held jointly with Cecelia Borg, Martijn Verburg and Reza Rehman.  This was an interactive conversation with a focus on the Java EE community survey results and encouraging more community participation and collaboration in Java development.  The Java 8 keynote by Georges Saab and Mark Reinhold was also very entertaining,  I was sorry to miss FOSDEM happening the previous weekend this year in Brussels, but I hope to attend in 2015.  Favorite take home gift -- Lambdas cap! In March, the inaugural version of the JavaLand conference happened inside Phantasialand, an amusement park in Germany. Markus Eisele suggested having an Early Adopters area at the conference, which I was keen to implement. In 2013 at Devoxx Belgium we held some activities in the Hackergaren area around Lambdas and Java EE 7, so this was a great opportunity to expand on a more interactive conference format and Andreas Badelt from the program committee helped in the planning for this area.  Daniel Bryant and Mani Sarkar from the London Java Community led some general Adopt-a-JSR discussions and AdoptOpen JDK activities.  JCP Spec Leads, Anatole Tresch from Credit Suisse, leading JSR 354, Money & Currency API, and Ed Burns from Oracle, leading JSR 344, JavaServer Faces 2.2, attended to engage with conference attendees on their JSRs.  Favorite - Stephen Chin's roller coaster video. In May, GeeCon in Krakow was anther awesome conference!  The conference organizers were warm and welcoming and I enjoyed time getting to know the other speakers at the event. There was a JCP and Adopt-a-JSR participation session as well as a moderated panel session on Early Adopters.  We had an amazing panel -- Daniel Bryant, Arun Gupta, Tomasz Borek , and Peter Lawrey. The panel discussed the Adopt-a-JSR and Adopt OpenJDK program, and how the participants work together to get involved and contribute to both the Java SE and Java EE platforms.  If was an interesting discussion and sparked some new ideas on how Java User Groups in Poland and around the world can contribute in a significant and meaningful way to create better and more practical Java standards today and in the future.  Favorite take home gift - GeeCon mug!   These were some of the highlights of the events--looking forward to Devoxx UK next week.  I will publish these details tomorrow!
