    Originally posted on: http://geekswithblogs.net/hroggero/archive/2014/08/21/about-the-new-microsoft-innovation-center-mic-in-miami.aspxLast night I attended a meeting at the new MIC in Miami, run by Blain Barton (@blainbar), Sr IT Pro Evangelist at Microsoft. The meeting was well attended and is meant to be run as a user group format in a casual setting. Many of the local Microsoft MVPs and group leaders were in attendance as well, which allows technical folks to connect with community leaders in the area. If you live in South Florida, I highly recommend to look out for future meetings at the MIC; most meetings will be about the Microsoft Azure platform, either IT Pro or Dev topics. For more information on the MIC, check out this announcement:  http://www.microsoft.com/en-us/news/press/2014/may14/05-02miamiinnovationpr.aspx.

  • Ubuntu 14.04 install fails with Via S3 UniChrome Pro graphics

    - by WizardNo.7
    I am trying to install Ubuntu 14.04 on a Fujitsu Siemens Amilo Pro laptop(it's quite old yes, has about 30GB Hard Drive and I think 192mb of RAM) which currently has Windows XP installed (which I'd like to keep for the time being). I have downloaded the 32-bit Desktop ISO and used unetbootin to create a Live USB for this laptop. When I boot from USB, I arrive at the unetbootin Grey and Blue menu and pick either "Try Ubuntu without installing", or "Install Ubuntu". The menu goes away and an Ubuntu loadscreen showing UBUNTU and four dots which progressively change between white and orange. At about the second color changing cycle a white underscore symbol appears next to the fourth dot and flickers. There is some leftover text from the kernel boot still visible, but there is no graphical desktop. After this I have to hard reboot or shut-down. $ lshw -c video *-display UNCLAIMED description: VGA compatible controller product: CN700/P4M800 Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro] Vendor: VIA Technologies, Inc. physical id: 0 bus info: pci@0000:01:00.0 version: 01 width: 32 bits clock: 66MHz capabilities: pm agp agp-2.0 vga_controller bus_master cap_list configuration: latency=64 mingnt=2 resources: memory:f0000000-f3ffffff memory:d1000000-d1ffffff

  • CUDA 4.1 Particle Update

    - by N0xus
    I'm using CUDA 4.1 to parse in the update of my Particle system that I've made with DirectX 10. So far, my update method for the particle systems is 1 line of code within a for loop that makes each particle fall down the y axis to simulate a waterfall: m_particleList[i].positionY = m_particleList[i].positionY - (m_particleList[i].velocity * frameTime * 0.001f); In my .cu class I've created a struct which I copied from my particle class and is as follows: struct ParticleType { float positionX, positionY, positionZ; float red, green, blue; float velocity; bool active; }; Then I have an UpdateParticle method in the .cu as well. This encompass the 3 main parameters my particles need to update themselves based off the initial line of code. : __global__ void UpdateParticle(float* position, float* velocity, float frameTime) { } This is my first CUDA program and I'm at a loss to what to do next. I've tried to simply put the particleList line in the UpdateParticle method, but then the particles don't fall down as they should. I believe it is because I am not calling something that I need to in the class where the particle fall code use to be. Could someone please tell me what it is I am missing to get it working as it should? If I am doing this completely wrong in general, the please inform me as well.

  • Documents stored on separate internal drive, Ubuntu doesn't notice on startup

    - by PlanoAlto
    My machine has Windows 7 Ultimate x64 and Ubuntu 12.04 LTS running side-by-side on a single hard drive with GRUB bootloader, each with 500 GB storage. I keep my personal documents on a separate 1TB hard drive so they remain isolated from any changes I make to the OS drive, but when Ubuntu starts it does not seem to notice my documents drive. While I've installed and worked with Ubuntu 12.04 Server x32 before, using it as a desktop OS is new to me. I use my documents drive for all of my personal data, including wallpapers and music, so it is imperative that Ubuntu recognize it on startup. Concerning the two specific examples: Ubuntu loads with the default blue-colored desktop instead of my desired picture of the spectacular Carina galaxy. When I right-click the desktop and select "Change Desktop Background", it wakes up from its amnesia and loads the proper background. As for my music, Rhythmbox defaults to an empty library upon reboot, forcing me to reload the settings manually each time. This gets quite tedious because I certainly can't work to my full potential without my music. The second thing I would like to address is making Ubuntu point the documents directories in ~ to their appropriate counterparts on the 1TB documents drive. I realize that this question is not new, but when I create the symbolical links, they established themselves inside the directories and did not convert the directories themselves into symbolical links. I also prefer not to move the files themselves from their current location on the 1TB drive. I believe this would also help the Rhythmbox library problem as well considering it's a default directory for the music player. Excerpt from fstab: proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sdb6 during installation UUID=057ac83e-76ad-460d-86e5-b6d46e9b1d80 / ext4 errors=remount-ro 0 1 # swap was on /dev/sdb7 during installation #UUID=1183df90-23fc-44e4-aa17-4e7c9865d5cb none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0 That's enough content for one question. I really like the Ubuntu experience so far since it doesn't treat me like an idiot out of the box (can't say the same for Windows) so I can't wait to hear from the community! Thanks for your help in advance.

  • Reverse-Engineer Driver for Backlit Keyboard

    - by user87847
    Here's my situation: I recently purchased a Sager NP9170 (same as the Clevo P170EM) and it has a multi-colored, backlit keyboard. Under Windows 7, you can launch an app that allows you to change the color of the backlighting to any of a handful of colors (blue, green, red, etc). I want that same functionality under Linux. I haven't been able to find any software that does this, so I guess I'm going to have to write it myself. I'm a programmer by trade, but I've haven't done much low level programming, and I've certainly never written a device driver, so I was wondering if anyone could answer these two questions: 1) Is there any software already out there that does this sort of thing? I've looked fairly thoroughly but haven't found anything applicable. 2) Where would I start in trying to reverse engineer this sort of thing? Any useful articles, tutorials, books that might help? And just to clarify: The backlighting already works, that's not the problem. I just want to be able to change the color of the backlighting. This functionality is supported by the hardware. The laptop came with windows software that does this and I want the same functionality in Linux. I am willing to write this software myself, I just want to know the best way to go about it. Thanks!

  • Hosting woes

    Unfortunately quite a few people have noticed our recent hosting problems, but if you are reading this they should all be over, so please accept our apologies. Our former web host decided migrate to a new platform, it had all sorts or great features, but on reflection hosting wasn’t one of them. We knew it was coming, and had even been proactive and requested several dates on their migration control panel so I could be around to check it afterwards. The dates came and went without anything happening, so we sat back and carried on on for a couple of months thinking they’d get back to us when they were ready. Then out of the blue I get an email saying it has happened! Now this is what I call timing, I had client work to complete, a 50 minute presentation to write and there was a little conference called SQLBits that I help organise at the end of the week, and then our hosting provider decides to migrate our sites. Unfortunately they only migrated parts of the sites, they forgot things like the database for SQLDTS. The database eventually appeared, but the data didn’t. Then the data pitched up but without the stored procedures. I was even asked if I could perform a backup and send it to them, as they were getting timeout errors. Never mind the issues of performing a native backup on a hosted server, whilst I could have done something, the question actually left me speechless. So you cannot access your own SQL server and you expect me to be able to help? This site was there, but hadn’t been set as an IIS application so all path references were wrong which meant no CSS and all the internal navigation and links were wrong. The new improved hosting platform Control Panel didn't appear to like setting applications. It said it would, you’d have to wait 2 hours of course, then just decided not to bother after all. So needless to say after a very successful SQLBits I focused my attention on finding a new web host, and here we are again. Sorry it took so long.

  • Win8 x64 Laptop (Samsung) unable to boot after installing Ubuntu

    - by user285872
    I posted here a while back and no one was able to help me so I am going to try to explain my problem better. I have a Samsung series 7 Ultrabook and I connected a USB optical drive with an Ubuntu 14.04 installation disc. I did not set or change any of my partitions, however, as I mainly wanted to just be able to boot from the disc and fool around with Ubuntu. Upon restarting my computer I get a blue-screen message saying: Recovery Your PC needs to be repiared The Boot configuration date file is missing some required information. File: \BCD Error Code: 0xc000000d You'll need to use the recovery tools on your installing media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer. However I am never given the option to even try to boot to anything. When I turn my computer on the optical drive spins and then after a moment or two comes to a halt. I turned off safeboot and switched it to CSM (I believe that is what it is called) mode, and that makes it so when I turn my computer on it takes me to a Windows Recovery screen. I am able to change the date I want to recover and view all the applications installed, however upon recovering Windows says "All boot options are tried. Press key to recover with factory image using Recovery or any other keys for next boot loop iteration." It seems to be stuck in a loop. Can someone please help me?! I'm so confused and nothing is working!

  • Hitching and Slowness Due to HDD Activity on Ubuntu, But Not Windows?

    - by Espionage724
    It's been bothering me for months now, but I've noticed in Ubuntu (or any distro of Linux I've tried), any major I/O activity will cause hitching and general slowness. For example, if I try doing a file transfer from my network computer to the computer I'm using and try moving the mouse after a while, it might not respond for a second or so. Similar incidents occur in other cases too (right-clicking to get a context menu takes a few seconds, hitting the drop-down application bar takes a while, etc). My HDD isn't top-notch (a WD Blue 500GB 7200RPM drive) but I don't recall it being nearly this bad in Windows 7, 8, or 8.1. CPU activity during file transfers is relatively low (less than 10-20% on all cores of a Phenom II X4 @ 3.3Ghz). I'm using Gnome System Monitor (on Xubuntu) and can't seem to see what kind of HDD activity is occurring though. I have 8GB of RAM too, which is moderately being used (2.5GB), but shouldn't be a problem either. Any ideas what's up? I've tried kernels between 3.8 and 3.11 (i'm using saucy currently with 3.11).

  • HDMI & Display Port stopped work on 11.10

    - by dizzy
    After upgraded two laptops to 11.10, HDMI and Display ports stopped to work. Symptoms on each (btw. it used to work with 11.04 on both): laptop Dell Inspiron 1525 (HDMI, Intel GMX 3100): after HDMI cable is plugged in, screen is corrupted (no panel, no icons), system is unresponsive, TV set receives some signal, but only blue screen and some regular ticks can be heard. Unplugging the cable system recovers. No logs were checked. Thinkpad W510 (DisplayPort, NVidia). Simple "Screens" utility does not recognizes TV set, but this is something to do with the differences between Nvidia driver API and the one expected from the utility, as far I could spot on the net. However, using Nvidia-settings, TV is recognized, but cannot be enabled and used. Beside that, touch pad freezes after HDMI2DisplayPort connector is plugged in the laptop (not immediately, but after few seconds - probably after some handshake with the TV set crashes). It is strange that no such bug reports can be found on the net. So, I guess it is something wrong on our laptops only, but would appreciate some hints (i.e. any known changes recently related to HDMI, Display Port, X-Windows, kernel... wherever I should take a look and fix the issue).

  • No text in working indicator-messages after enabling different icons depending on the status

    - by user106750
    My indicator-messages has some problems. As you can see in the image, there appears no text. The indicator is working correctly, if there is some income, a number will appear in its proper place or I will be able to see the minutes passed after I got an email, but still no information. As you can see in the picture, I changed the envelope icon for the status one. I configured it as is indicated in http://www.omgubuntu.co.uk/2012/08/ubuntu-add-new-message-indicator-icons, with the indicator changing depending on the status. But I modified it so I see the bubble. The bubble gets the arrow when I'm absent, for example, or an "X" of I'm disconnected, and also turns blue if there an income. I believe the problem is related with this new indicator. The first days, it was working fine, but then the text dissapeared. I've tried uninstalling and reinstalling the packet, with no success. I'm using ubuntu 12.10 64bits with Unity. Someone has an idea how to fix this? I would prefer conserving the characteristic of having different icons. Thanks a lot!!!

  • How to use lists in equivalence partitioning?

    - by KhDonen
    I have read that equivalence partitioning can be used typically for intervals or lists, e.g. I assume it can be used for every set of inputs. Anyway if the requirement says that allowed colors are (RED,BLUE,BLACK, GREEN), I cannot treat them like a list, right? I mean, testing one of them would not be enough because developers most likely used some switch-case and thus it is not real "set" where one could represent also the others. So how it is meant with lists? Also what is not that clear to me, I do not think it is always possible to do the initial partioning and then design the test cases. What about checking two lines intersection: Y=MX+C. (two inputs) 1) The lines are paraller. M1=M1 but C1 must be different from C2. 2) Lines are intersecting. M1 must be different from M2. 3) Coincident. The are the same. How can I use partitioning here? THis is actually taken from a book and it says that these sets are eq.classes.

  • b43 Firmware Error when trying to install Ubuuntu 14.04 on XP Laptop

    - by WizardNo.7

I cannot access the boot options menu by using F6 or similar. Any ideas? Thanks beforehand!

  • How to dual boot Ubuntu 12.10 and Windows XP sp3 on Dell Dimension 8250 desktop using 2 hard drives

    - by user106055
    I'd like instructions to dual boot Ubuntu 12.10 and Windows XP (sp3) on my desktop Dell Dimension 8250 (this is old and has 1.5 GB RAM which is maximum). I will be using 2 hard drives. Windows XP is already on a 120 GB drive and and Ubuntu 12.10 will go on a separate 80 GB hard drive. Both drives are IDE using a 80 conductor cable where the 40 pin blue connector connects to the motherboard. The middle connector is gray and is "normally" used for slave (device 1) and the black connector at the very end of the cable is meant for the master drive (device 0) or a single drive if only one is used. First, I do not wish the XP drive to have its boot modified by Ubuntu in any way. It should remain untouched...virgin. Let me know where the XP drive and the Ubuntu drive should be connected based upon the cable I've mentioned above, as well as jumper settings for both during the whole process. I'm just guessing, but should I remove the XP drive and put the empty Ubuntu drive in its place and install Ubuntu? By the way, I already have made the DVD ISO disk. For your information, the BIOS for this machine is version A03. When I tap F12 to get to the boot menu, I have the following choices: Normal (this will take me to a black screen with white type giving me the choice to boot to XP or to my external USB backup recovery drive) Diskette Drive Hard-Disk Drive c: IDE CD-ROM Drive (Note that if the CD Drive is empty, it will then go to the DVD drive) System Setup IDE Drive Diagnostics Boot to Utility Partition (This is Dell's various testing utilities) Thank you in advance for your help.

  • Configuring correct port for Oozie (invoking PIG script) in Cloudera Hue

    - by user2985324
    I am new to CDH4 Oozie workflow editor. While trying to invoke a pig script from Oozie workflow editor, i am getting the following error. HadoopAccessorException: E0900: Jobtracker [mymachine:8032] not allowed, not in Oozies whitelist It looks like Oozie is submitting the job to Yarn port (8032). I want it to submit to 8021 (MR jobtracker) port. Can someone help me in identify where to set the job tracker URL or port so that oozie picks up the correct one (using Hue or Cloudera manager). Previously I tried the following but none of them helped Modfied workflow.xml file /user/hue/oozie/workspaces/../workflow.xml file. However it gets overwritten when I submit the job from workflow editor. In cloudera Manager -- oozie -- configuration --Oozie Server (advanced) -- Oozie Server Configuration Safety Valve for oozie-site.xml property I set the following- <property> <name>oozie.service.HadoopAccessorService.nameNode.whitelist</name> <value>mymachine:8020</value> oozie.service.HadoopAccessorService.jobTracker.whitelist mymachine:8021 and restarted the oozie service. 3. Tried to override 'jobTracker' property while configuring the pig task. This appears as follows in the workflow file however it doesn't take effect (or doesn't override) and still uses 8032 port. <global> <configuration> <property> <name>jobTracker</name> <value>mymachine:8021</value> </property> </configuration> </global> I am using CDH4 version. Thanks for looking into my question.

  • C# Design How to Elegantly wrap a DAL class

    - by guazz
    I have an application which uses MyGeneration's dOODads ORM to generate it's Data Access Layer. dOODad works by generating a persistance class for each table in the database. It works like so: // Load and Save Employees emps = new Employees(); if(emps.LoadByPrimaryKey(42)) { emps.LastName = "Just Got Married"; emps.Save(); } // Add a new record Employees emps = new Employees(); emps.AddNew(); emps.FirstName = "Mr."; emps.LastName = "dOOdad"; emps.Save(); // After save the identity column is already here for me. int i = emps.EmployeeID; // Dynamic Query - All Employees with 'A' in thier last name Employees emps = new Employees(); emps.Where.LastName.Value = "%A%"; emps.Where.LastName.Operator = WhereParameter.Operand.Like; emps.Query.Load(); For the above example(i.e. Employees DAL object) I would like to know what is the best method/technique to abstract some of the implementation details on my classes. I don't believe that an Employee class should have Employees(the DAL) specifics in its methods - or perhaps this is acceptable? Is it possible to implement some form of repository pattern? Bear in mind that this is a high volume, perfomacne critical application. Thanks, j

  • Facebooker Causing Problems with Rails Integration Testing

    - by Eric Lubow
    I am (finally) attempting to write some integration tests for my application (because every deploy is getting scarier). Since testing is a horribly documented feature of Rails, this was the best I could get going with shoulda. class DeleteBusinessTest < ActionController::IntegrationTest context "log skydiver in and" do setup do @skydiver = Factory( :skydiver ) @skydiver_session = SkydiverSession.create(@skydiver) @biz = Factory( :business, :ownership = Factory(:ownership, :skydiver = @skydiver )) end context "delete business" do setup do @skydiver_session = SkydiverSession.find post '/businesses/destroy', :id = @biz.id end should_redirect_to('businesses_path()'){businesses_path()} end end end In theory, this test seems like it should pass. My factories seem like they are pushing the right data in: Factory.define :skydiver do |s| s.sequence(:login) { |n| "test#{n}" } s.sequence(:email) { |n| "test#{n}@example.com" } s.crypted_password '1805986f044ced38691118acfb26a6d6d49be0d0' s.password 'secret' s.password_confirmation { |u| u.password } s.salt 'aowgeUne1R4-F6FFC1ad' s.firstname 'Test' s.lastname 'Salt' s.nickname 'Mr. Password Testy' s.facebook_user_id '507743444' end The problem I am getting seems to be from Facebooker only seems to happen on login attempts. When the test runs, I am getting the error: The error occurred while evaluating nil.set_facebook_session. I believe that error is to be expected in a certain sense since I am not using Facebook here for this session. Can anyone provide any insight as to how to either get around this or at least help me out with what is going wrong?

  • Make a Crystal Report with data fetched from two differents tables

  • What was Tim Sweeney thinking? (How does this C++ parser work?)

    - by Frank Krueger
    Tim Sweeney of Epic MegaGames is the lead developer for Unreal and a programming language geek. Many years ago posted the following screen shot to VoodooExtreme: As a C++ programmer and Sweeney fan, I was captivated by this. It shows generic C++ code that implements some kind of scripting language where that language itself seems to be generic in the sense that it can define its own grammar. Mr. Sweeney never explained himself. :-) It's rare to see this level of template programming, but you do see it from time to time when people want to push the compiler to generate great code or because they want to create generic code (for example, Modern C++ Design). Tim seems to be using it to create a grammar in Parser.cpp - you can see what look like prioritized binary operators. If that is the case, then why does Test.ae look like it's also defining a grammar? Obviously this is a puzzle that needs to be solved. Victory goes to the answer with a working version of this code, or the most plausible explanation, or to Tim Sweeney himself if he posts an answer. :-)

  • Using inotify-tools and ruby to push uploads to Cloud Files

    - by Christian
    Hi Guys, I wrote a few scripts to monitor an uploads directory for changes, then capture the file uploaded/changed and push it to cloud files using a ruby script. This all works well 95% of the time, the only exception is that occasionally, ruby fails with a 'file does not exist' exception. I am assuming that the ruby 'push' script is being called before the file is 100% in its new location, so the script is being called a little prematurely. I tried adding a little function to my script to check if the file exists, if it doesn't, sleep 5 then try again, but this seems to snowball and eventually dies. I then just added a sleep 2 to all calls, but it hasn't helped as I now get the 'file does not exist' error again. #!/bin/sh function checkExists { if [ ! -e "$1" ] then sleep 5 checkExists $1 fi } inotifywait -mr --timefmt '%d/%m/%y-%H:%M' --format '%T %w %f' -e modify,moved_to,create,delete /home/skylines/html/forums/uploads | while read date dir file; do cloudpath=${dir:20}${file} localpath=${dir}${file} #checkExists $localpath sleep 2 ruby /home/cbiggins/bin/pushToCloud.rb skylinesaustralia.com $cloudpath $localpath echo "${date} ruby /home/cbiggins/bin/pushToCloud.rb skylinesaustralia.com $cloudpath $localpath" >> /var/log/pushToCloud.log done I am looking for any suggestions to help me make this 100% stable (eventually, I'll serve the uploaded files from Cloud FIles, so I need to make sure its perfect) Thanks in advance!

  • Qt Object Linker Problem " undefined reverence to vtable"

    - by Thomas
    This is my header: #ifndef BARELYSOCKET_H #define BARELYSOCKET_H #include <QObject> //! The First Draw of the BarelySocket! class BarelySocket: public QObject { Q_OBJECT public: BarelySocket(); public slots: void sendMessage(Message aMessage); signals: void reciveMessage(Message aMessage); private: // QVector<Message> reciveMessages; }; #endif // BARELYSOCKET_H This is my class: #include <QTGui> #include <QObject> #include "type.h" #include "client.h" #include "server.h" #include "barelysocket.h" BarelySocket::BarelySocket() { //this->reciveMessages.clear(); qDebug("BarelySocket::BarelySocket()"); } void BarelySocket::sendMessage(Message aMessage) { } void BarelySocket::reciveMessage(Message aMessage) { } I get the Linker Problem : undefined reference to 'vtable for barelySocket' This should mean, i have a virtual Function not implemented. But as you can see, there is non. I comment the vector cause that should solve the Problem, but i does not. The Message is a complex struct, but even converting it to int did not solve it. I searched Mr G but he could not help me. Thank you for your support, Thomas

  • scipy.io typeerror:buffer too small for requested array

    - by kartiku
    I have a problem in python. I'm using scipy, where i use scipy.io to load a .mat file. The .mat file was created using MATLAB. listOfFiles = os.listdir(loadpathTrain) for f in listOfFiles: fullPath = loadpathTrain + '/' + f mat_contents = sio.loadmat(fullPath) print fullPath Here's the error: Traceback (most recent call last): File "tryRankNet.py", line 1112, in demo() File "tryRankNet.py", line 645, in demo mat_contents = sio.loadmat(fullPath) File "/usr/lib/python2.6/dist-packages/scipy/io/matlab/mio.py", line 111, in loadmat matfile_dict = MR.get_variables() File "/usr/lib/python2.6/dist-packages/scipy/io/matlab/miobase.py", line 356, in get_variables getter = self.matrix_getter_factory() File "/usr/lib/python2.6/dist-packages/scipy/io/matlab/mio5.py", line 602, in matrix_getter_factory return self._array_reader.matrix_getter_factory() File "/usr/lib/python2.6/dist-packages/scipy/io/matlab/mio5.py", line 274, in matrix_getter_factory tag = self.read_dtype(self.dtypes['tag_full']) File "/usr/lib/python2.6/dist-packages/scipy/io/matlab/miobase.py", line 171, in read_dtype order='F') TypeError: buffer is too small for requested array The whole thing is in a loop, and I checked the size of the file where it gives the error by loading it interactively in IDLE. The size is (9,521), which is not at all huge. I tried to find if I'm supposed to clear the buffer after each iteration of the loop, but I could not find anything. Any help would be appreciated. Thanks.

  • Issues in Convergence of Sequential minimal optimization for SVM

    - by Amol Joshi
    I have been working on Support Vector Machine for about 2 months now. I have coded SVM myself and for the optimization problem of SVM, I have used Sequential Minimal Optimization(SMO) by Mr. John Platt. Right now I am in the phase where I am going to grid search to find optimal C value for my dataset. ( Please find details of my project application and dataset details here http://stackoverflow.com/questions/2284059/svm-classification-minimum-number-of-input-sets-for-each-class) I have successfully checked my custom implemented SVM`s accuracy for C values ranging from 2^0 to 2^6. But now I am having some issues regarding the convergence of the SMO for C 128. Like I have tried to find the alpha values for C=128 and it is taking long time before it actually converges and successfully gives alpha values. Time taken for the SMO to converge is about 5 hours for C=100. This huge I think ( because SMO is supposed to be fast. ) though I`m getting good accuracy? I am screwed right not because I can not test the accuracy for higher values of C. I am actually displaying number of alphas changed in every pass of SMO and getting 10, 13, 8... alphas changing continuously. The KKT conditions assures convergence so what is so weird happening here? Please note that my implementation is working fine for C<=100 with good accuracy though the execution time is long. Please give me inputs on this issue. Thank You and Cheers.

  • c#: how to read parts of a file? (DICOM)

    - by Xaisoft
    I would like to read a DICOM file in C#. I don't want to do anything fancy, I just for now would like to know how to read in the elements, but first I would actually like to know how to read the header to see if is a valid DICOM file. It consists of Binary Data Elements. The first 128 bytes are unused (set to zero), followed by the string 'DICM'. This is followed by header information, which is organized into groups. A sample DICOM header First 128 bytes: unused DICOM format. Followed by the characters 'D','I','C','M' Followed by extra header information such as: 0002,0000, File Meta Elements Groups Len: 132 0002,0001, File Meta Info Version: 256 0002,0010, Transfer Syntax UID: 1.2.840.10008.1.2.1. 0008,0000, Identifying Group Length: 152 0008,0060, Modality: MR 0008,0070, Manufacturer: MRIcro In the above example, the header is organized into groups. The group 0002 hex is the file meta information group which contains 3 elements: one defines the group length, one stores the file version and the their stores the transfer syntax. Questions How to I read the header file and verify if it is a DICOM file by checking for the 'D','I','C','M' characters after the 128 byte preamble? How do I continue to parse the file reading the other parts of the data?

  • Using Regex Replace when looking for un-escaped characters

    - by Daniel Hollinrake
    I've got a requirement that is basically this. If I have a string of text such as "There once was an 'ugly' duckling but it could never have been \'Scarlett\' Johansen" then I'd like to match the quotes that haven't already been escaped. These would be the ones around 'ugly' not the ones around 'Scarlett'. I've spent quite a while on this using a little C# console app to test things and have come up with the following solution. private static void RegexFunAndGames() { string result; string sampleText = @"Mr. Grant and Ms. Kelly starred in the film \'To Catch A Thief' but not in 'Stardust' because they'd stopped acting by then"; string rePattern = @"\\'"; string replaceWith = "'"; Console.WriteLine(sampleText); Regex regEx = new Regex(rePattern); result = regEx.Replace(sampleText, replaceWith); result = result.Replace("'", @"\'"); Console.WriteLine(result); } Basically what I've done is a two step process find those characters that have already been escaped, undo that then do everything again. It sounds a bit clumsy and I feel that there could be a better way.
