  • Mac Mini won't boot with USB Drive connected

    - by Jens
    Newbie here. I have a 2012 MacMini with 2 x 3Tb Seagate GoFlex Desk external hard drives. Both drives have their own power supplies and work perfectly. I use both MacOS and Windows7 on the Mac for different reasons. Both boot and work fine. The only problem is neither MacOS or Windows will boot while the two USB drives are connected. I must disconnect the USB cables, boot and reconnect them. Then all works fine. Its rather annoying since this is mostly a Media Centre and you really don't want to be playing with cables every day, and I don't leave my stuff on over night. Can anyone help? Thanks Jens

  • List of MD /Raid/LVM (Devices) = How to mount them without any further information available?

    - by Jens
    Hello Expets, I do not have much skills in linux and installed a system two years ago that I now had to reboot, but it seems I did not automate everything with start-scripts... My Problem: I miss some mountpoints. I have a list of my raids (excerpt:) md3 : active (auto-read-only) raid1 sda6[0] sdb6[1] 97659008 blocks [2/2] [UU] md4 : active (auto-read-only) raid1 sda7[0] sdb7[1] 250099776 blocks [2/2] [UU] and it seems md3 and md4 are NOT mounted. However i do NOT have any entries for them fstab file. What should I do next. I do NOT know which filesystem they have (most likely ext3). =Can I savely try to mount them with (mount -t ext3 /dev/md3 /mnt/mymntpoint) or will the lead to corrupted data, in case they are not ext3? What should I do next (based on the information given above). The goal is to remount these Devices again, but I do not know anything about them anymore... Thank you very much Jens

  • (Open Source) Cloud-Filesystem to run a Database on Top?

    - by jens
    Hello, what are current "technologies and implementations" to get a filesystem with unlimited capacity by using single servers with their harddisk to form a "grid/cloud filesystem"? I need to have unlimited space (by adding further servers) but it must be a filesysem that is capable of running a database on top. I know of Apache Hadoop but that seems not be be Ideal for running a DB on top of it (or am I wrong??) And iSCSI seems to be "remote/networked" but I do not know how and if this is clusterable? thank you very much!! jens

  • ng-grid checkbox with filtering

    - by WilliamLou
    If I have a huge table with ng-grid, and I enabled a checkbox to select all. Is there a way for me to combine this selectAll feature with the filtering box. I mean when I filter out the rows, I want to click the checkbox so that the rows filtered will be all selected; once I clean out filter, those selectedRows are still left so that I can add more rows into it with other filters. I created a Plunker code template here. copy code here as well: // main.js var app = angular.module('myApp', ['ngGrid']); app.controller('MyCtrl', function($scope) { $scope.mySelections = []; $scope.myData = [{name: "Moroni", age: 50}, {name: "Tiancum", age: 43}, {name: "Jacob", age: 27}, {name: "Nephi", age: 29}, {name: "Enos", age: 34}, {name: "Moroni", age: 50}, {name: "Tiancum", age: 43}, {name: "Jacob", age: 27}, {name: "Nephi", age: 29}, {name: "Enos", age: 34}, {name: "Moroni", age: 50}, {name: "Tiancum", age: 43}, {name: "Jacob", age: 27}, {name: "Nephi", age: 29}, {name: "Enos", age: 34}, {name: "Moroni", age: 50}, {name: "Tiancum", age: 43}, {name: "Jacob", age: 27}, {name: "Nephi", age: 29}, {name: "Enos", age: 34},]; $scope.filterOptions = { filterText: '' }; $scope.gridOptions = { data: 'myData', checkboxHeaderTemplate: '<input class="ngSelectionHeader" type="checkbox" ng-model="allSelected" ng-change="toggleSelectAll(allSelected)"/>', showSelectionCheckbox: true, selectWithCheckboxOnly: false, selectedItems: $scope.mySelections, multiSelect: true, filterOptions: $scope.filterOptions }; });

  • Java JMS = HornetQ = javax.jms.JMSSecurityException: Unable to validate user: null ?

    - by jens
    Hello Experts, I am trying for several hours to get the HornetQ Examples running in Eclipse. Using the Standalone Examples everything works fine, but when I run the examples in Eclipse I get the following error: javax.jms.JMSSecurityException: Unable to validate user: null What could this error mean? Where do I have to specify the user? Maybe HornetQ tries to look this user up in "Some Context/Properties" etc , but I do not know where and how to specifiy the user HornetQ is running under. What i did: 1.)Started Default HornetQ Server with the start.sh Script in the ./bin directory 2.)Copied the QueueExample over to eclpise 3.)Did some minor changes in the config files (to have the same Queue Names...) (I also tried to disable security completely by setting: <security-enabled>false</security-enabled> but with no success, always getting the same error. Also when trying to programmatically instance HornetQ only via classes I get this error too). Thank you very much!! Jens

  • Asynchronous Processing = Spanning Threads = Valid?

    - by jens
    Hello Experts, am I allowed (without any sideeffects) to create and start a new Thread() from within a doGet() Method of a servlet? Or does this somehow leak ressources? Is it valid to also pass the "Session" Object into the Thread to later save the result of my asynchronous processing (I will synchronized correctly) in the session? Or will this leak ressources when using the session "in indepedant threads"? = What would happen if the session meanwhile would be expired by the webcontainer as it has timedout and I will access it from my thread? Or would could this also lead to the sideffect, that storing the session in the thread will prevent the webcontainer from expiring the session at all (and therefore finally leak ressources as the sessions do not get cleared up)? (I know there are other Solutions, like working with DB-(Job)Records, JMS or Servlets 3.0) but I need so solve the problem as described by spanning a new Thread within doGet.) Thank you very much!! Jens

  • JQuery: NOT using document.ready and inserting HTML Tags = is this allowed?

    - by jens
    Hello, is this a valid JQuery usage pattern to : <script type="text/javascript"> $("body").prepend('<input type="hidden" id="error" value="show">'); </script> That is using Jquery to manipulate / insert HTML Tags when the Document has NOT YET been loaded (by not using document.ready for the inserting into the DOM)? (Normally I only use document.ready, but in this case I need to insert some Information into the DOM that then is present, when document.ready is called. This is some kind of "happens-before" relations ship I want to achieve so that I am shure when document.ready is called the inserted Form field is available in the document, as I depend on that information. Thank you very much jens

  • Java Compiler: Optimization of "cascaded" ifs and best practices?

    - by jens
    Hello, does the Java Compiler optimize a statement like this if (a == true) { if (b == true) { if (c == true) { if(d == true) { //code to process stands here } } } } to if (a == true && b==true && c==true && d == true) So thats my first question: Do both take exactly the same "CPU Cycles" or is the first variant "slowlier". My Second questin is, is the first variant with the cascaded if considered bad programming style as it is so verbose? (I like the first variant as I can better logically group my expressions and better comment them (my if statements are more complex than in the example), but maybe thats bad proramming style?) and even slowlier, thats why I am asking... Thanks Jens

  • Server crash = How does a TCP/IP (and the browser-client) behave after this?

    - by jens
    Hello Experts, i would be thankfull for an explanation what happens with HTTP(TCP/IP) transmissions when the server crashes unexpectedly, how does the client Browser (Firefox / IE) handle this event. What happens in the following two standard cases: Clients-actively sends data: The TCP/IP Connection has been estableshed and the Client (Web-Browser) is Sending a POST Request with some data and in the middle of the process of sending the server crashes. What does this mean for the client? As far as I know TCP/IP does not "acknowledge" a send data-package so the client does not know that the server crashed. How will the client behave? (Firefox and Internet Explorer)? The Server is actively sending data: As above the tcp/ip connection has been established and the Server is sending a large website to the client (browser). In the middle of the sending-process the server crashes, so no futher packets are sent. How does the client browser react to this event (Firefox and Interne Expolrer) Thank you very much!! Jens

We also have two strong .NET presenters – Mahesh and Prabhjot. During this event, there will be plenty of giveaways, lots of fun, demos and pure technical talk, specifically no marketing and promotion – just pure technical talk. The most interesting part is that all the SQL Legends – Jacob, Rushabh and Vinod are for sure presenting on SQL Server but with a twist. Jacob – He is going to talk about .NET and SQL – Optimization Techniques Rushabh – He is going to talk about SQL and BI – Self Service BI Vinod – He is going to talk about professional development of developers – Managing Time Pinal – Best Practices for SharePoint Database Administrators – SharePoint DBA – I have presented this session earlier. I promise this event is going to be one of the best events held ever.

  • wrestling with some rewrites for Apache...

    - by Evert
    Hi all, I have upgraded my gallery2 to gallery3, and notice that some links no longer resolve correctly. Since the proper way is to redirect these with a 301, that is the way I'm going. The following series need redirecting: folders: old: http://photo.meulie.net/v/various/Gry/ new: http://photo.meulie.net/various/Gry/ pages: old: http://photo.meulie.net/v/Jacob/02112008310.jpg.html new: http://photo.meulie.net/Jacob/02112008310 (both are of course just examples. there are 100's of folders & files to redirect...) I think there were/are also direct links to images, but those I'm not bothering with for now. Who can help me out? :-) Regards, Evert

  • Hibernate: Dirty Checking and Only Update of Dirty Attributes?

    - by jens
    Hello Experts, in "good old JDBC days" I wrote a lot of SQL Queries that did very targeted updates of only the "attributes/members" that were actually changed: For Example having an object with the following members: public String name; public String address; public Date date; If only date was changed in some Business Method I would only issue an SQL UPDATE for the date member. ==It seems however (thats my "impression" of hibernate) that when working with a standard Hibernate mapping (mapping the full class), even updates of only one single member lead to a full update of the object in SQL Statements generated by Hibernate. My Questions are: 1.) Is this observation correct, that hibernate DOES NOT intelligently check (in a fully mapped class), what member(s) where changed and then only issue updates for the specific changed members, but rather always will update (in the generated SQL Update Statement) all mapped members (of a class), even if they were not changed (in case the object is dirty due to one member being dirty...) 2.) What can I do to make Hibernate only update those members, that have been changed? I am searching for a solution to have hibernate only update the member that actually changed. (I know hibernate does some big work on doing dirty-checking, but as far as I know this dirtychecking is only relevant to identify if the object as whole is dirty, not what single member is dirty.) Thank you very much! Jens

  • Java Concurrency : Synchronized(this) => and this.wait() and this.notify()

    - by jens
    Hello Experts, I would appreciate your help in understand a "Concurrency Example" from: http://forums.sun.com/thread.jspa?threadID=735386 Qute Start: public synchronized void enqueue(T obj) { // do addition to internal list and then... this.notify(); } public synchronized T dequeue() { while (this.size()==0) { this.wait(); } return // something from the queue } Quote End: My Question is: Why is this code valid? = When I synchronize a method like "public synchronized" = then I synchronize on the "Instance of the Object == this". However in the example above: Calling "dequeue" I will get the "lock/monitor" on this Now I am in the dequeue method. As the list is zero, the calling thread will be "waited" From my understanding I have now a deadlock situation, as I will have no chance of ever enquing an object (from an nother thread), as the "dequeue" method is not yet finised and the dequeue "method" holds the lock on this: So I will never ever get the possibility to call "enequeue" as I will not get the "this" lock. Backround: I have exactly the same problem: I have some kind of connection pool (List of Connections) and need to block if all connections are checked. What is the correct way to synchronize the List to block, if size exceeds a limit or is zero? Thank you very much Jens

  • Java Instance of: Supertypes und Subtypes seem to be equal? How to test exaclty for Type?

    - by jens
    Hello, i would be thankful for your advice. I need to test, if an instance is exactly of a given type. But it seems that instanceof returns true also if the subtype is tested for the supertype (case 3). I never knew this before and I am quite surprised. Am I doing something wrong here? How do I exactly test for a given typen? //.. class DataSourceEmailAttachment extends EmailAttachment //... EmailAttachment emailAttachment = new EmailAttachment(); DataSourceEmailAttachment emailAttachmentDS = new DataSourceEmailAttachment(); if (emailAttachment instanceof EmailAttachment){ System.out.println(" 1"); } if (emailAttachment instanceof DataSourceEmailAttachment){ System.out.println(" 2"); } if (emailAttachmentDS instanceof EmailAttachment){ System.out.println(" 3 "); } if (emailAttachmentDS instanceof DataSourceEmailAttachment){ System.out.println(" 4"); } RESULT: 1 3 4 I want to avoid case 3, I only want "exact matches" (case 1 and 4) how to thest for them?? thanks!!!

  • How do I place a DIV tag image on the very top of the page in HTML5?

    - by Jacob
    Hello there. I'm trying to put an x-repeat "grid" of images by using background-image in CSS, then using the id in a DIV tag. My intention is to put a sort of "panel", then always extends to the very top of the page, and loops with repeat-x. It works just fine without a DOCTYPE, but when I put the clean in the code, it pushes the image in the tag downwards, as if there's a margin on the top of the page of about 15 px or so. I tried top-margin, z-index, with no success. Excuse me if I'm asking a silly question, but I'm sort of new. Thanks, -Jacob

  • Converting excel files to python to frequency

    - by Jacob
    Essentially I've got an excel files with voltage in the first column, and time in the second. I want to find the period of the voltages, as it returns a graph of voltage in y axis and time in x axis with a periodicity, looking similar to a sine function. To find the frequency I have uploaded my excel file to python as I think this will make it easier- there may be something I've missed that will simplify this. So far in python I have: import xlrd import numpy as N import numpy.fft as F import matplotlib.pyplot as P wb = xlrd.open_workbook('temp7.xls') #LOADING EXCEL FILE wb.sheet_names() sh = wb.sheet_by_index(0) first_column = sh.col_values(1) #VALUES FROM EXCEL second_column = sh.col_values(2) #VALUES FROM EXCEL Now how do I find the frequency from this? Huge thanks to anyone who can help! Jacob

  • How to get a list of names + a count of occurrences relating to the name from another table

    - by Jacob Degeling
    Hi, Hope my subject line was descriptive enough. Basically, I have a table called Students, and one called Absences. The Students table contains student information (Name, DOB, StudentID etc.), the Absences table contains any absences (Date, Reason, related by StudentID). I want to get a full list of the students, plus a count of their absences. Sample results would be: StudentName Absences ------------- ----------- Johnny 3 Mark 2 James 1 Anthony 0 Sharon 0 Can someone suggest a way I should tackle this problem? I would prefer to have a single SQL statement, possibly incorporating some views etc. Thanks, Jacob.
