  • Recover backup copy of a ubuntu linux installation on a usb stick using dd

    - by Werner
    Hi, I installed Ubuntu 10.04 on a usb stick in persistent install mode. So I could boot the laptop or my desktop computer with the stick, at boot time. Once I needed the 8GB stick for another purposes so I thought about coyping it to my desktop doing from mac os x: dd if=/dev/disks3s of=/Users/jack/Desktop/usb_copy Now I am trying to do the opposite, after having used the stick, which was formatted to NTFS, just doing dd if=/Users/jack/Desktop/usb_copy of=/dev/disks3s but although I can see that almost of the files are there, I can not boot again. IT is also strange the the file permissions are kind of strange, something like _user What can I do ? Thanks

  • Resize Ext.form.ComboBox to fit its content

    - by ITRushn
    There are quite few solutions on Ext forums, but I wasn’t able to get any of them work. It seems I am missing something minor. I need to resize combobox to fit its content when it’s first created. I do not need to worry about resizing it when content is changing. Is there any working examples using Extjs 3.2? Current Code: var store = new Ext.data.ArrayStore({ fields: ['view', 'value', 'defaultselect'], data: Ext.configdata.dataCP }); comboCPU = new Ext.form.ComboBox({ tpl: '<tpl for="."><div class="x-combo-list-item"><b>{view}</b><br /></div></tpl>', store: store, displayField: 'view', width: 600, typeAhead: true, forceSelection: true, mode: 'local', triggerAction: 'all', editable: false, emptyText: 'empty text', selectOnFocus: true, listeners: { select: AdjustPrice, change: AdjustPrice, beforeselect: function (combo, record, index) { return ('false' == record.data.disabled); } }, applyTo: 'confelement' }); I've also tried removing width: 600 and replacing it with minListWidth: 600 but that result following and didnt fix the issue.

  • Linux core dumps are too large!

    - by themoondothshine
    Hey guys, Recently I've been noticing an increase in the size of the core dumps generated by my application. Initially, they were just around 5MB in size and contained around 5 stack frames, and now I have core dumps of 2GBs and the information contained within them are no different from the smaller dumps. Is there any way I can control the size of core dumps generated? Shouldn't they be at least smaller than the application binary itself? Binaries are compiled in this way: Compiled in release mode with debug symbols (ie, -g compiler option in GCC). Debug symbols are copied onto a separate file and stripped from the binary. A GNU debug symbols link is added to the binary. At the beginning of the application, there's a call to setrlimit which sets the core limit to infinity -- Is this the problem?

  • First Call to a Controller, Constant is defined, Second call, "uninitialized constant Oauth"?

    - by viatropos
    I am trying to get the OAuth gem to work with Rails 3 and I'm running into this weird problem... (independent of the gem, I think I've run into this once before) I have a controller called "OauthTestController", and a model called "ConsumerToken". The model looks like this. require 'oauth/models/consumers/token' class ConsumerToken < ActiveRecord::Base include Oauth::Models::Consumers::Token end When I go to "/oauth_test/twitter", it loads the Oauth::Models::Consumers::Token module and I'm able to connect to twitter no problem. But the second time I try it (just refresh the /oauth_test/twitter url), it gives me this error: NameError (uninitialized constant Oauth): app/models/consumer_token.rb:4 app/models/twitter_token.rb:2 app/controllers/oauth_test_controller.rb:66:in `load_consumer' Why is that? It has something to do with load paths or being in development mode maybe?

  • WPF ListView.CurrentChanged too fast for binding

    - by matt
    My case: MVVM ListView+Details(custom UserControl) List bound to MV.Items (IsSynchronizedWithCurrent=true) Details bound to MV.Items.Current MV.Items.Count == 100 about 0.2sec to read details (lazy mode) When I hold the down arrow on the list, very strange things happen: list items order change current changes in the random order CPU usage drastically increments and eventually all hangs. I've read some post that one should start the timer or run handler in the background, but I am not able to do that, since all the binding WPF does for me. Is there some way to instruct the binding in my DetailsControl, to wait a while before accepting CurrentItem? Or should I just resign from the clean solution and write custom code in my MV to handle that?

  • Hadoop on windows server

    - by Luca Martinetti
    Hello, I'm thinking about using hadoop to process large text files on my existing windows 2003 servers (about 10 quad core machines with 16gb of RAM) The questions are: Is there any good tutorial on how to configure an hadoop cluster on windows? What are the requirements? java + cygwin + sshd ? Anything else? HDFS, does it play nice on windows? I'd like to use hadoop in streaming mode. Any advice, tool or trick to develop my own mapper / reducers in c#? What do you use for submitting and monitoring the jobs? Thanks

  • Fibre channel long distance woes

    - by Marki
    I need a fresh pair of eyes. We're using a 15km fibre optic line across which fibrechannel and 10GbE is multiplexed (passive optical CWDM). For FC we have long distance lasers suitable up to 40km (Skylane SFCxx0404F0D). The multiplexer is limited by the SFPs which can do max. 4Gb fibrechannel. The FC switch is a Brocade 5000 series. The respective wavelengths are 1550,1570,1590 and 1610nm for FC and 1530nm for 10GbE. The problem is the 4GbFC fabrics are almost never clean. Sometimes they are for a while even with a lot of traffic on them. Then they may suddenly start producing errors (RX CRC, RX encoding, RX disparity, ...) even with only marginal traffic on them. I am attaching some error and traffic graphs. Errors are currently in the order of 50-100 errors per 5 minutes when with 1Gb/s traffic. Optics Here is the power output of one port summarized (collected using sfpshow on different switches) SITE-A units=uW (microwatt) SITE-B ********************************************** FAB1 SW1 TX 1234.3 RX 49.1 SW3 1550nm (ko) RX 95.2 TX 1175.6 FAB2 SW2 TX 1422.0 RX 104.6 SW4 1610nm (ok) RX 54.3 TX 1468.4 What I find curious at this point is the asymmetry in the power levels. While SW2 transmits with 1422uW which SW4 receives with 104uW, SW2 only receives the SW4 signal with similar original power only with 54uW. Vice versa for SW1-3. Anyway the SFPs have RX sensitivity down to -18dBm (ca. 20uW) so in any case it should be fine... But nothing is. Some SFPs have been diagnosed as malfunctioning by the manufacturer (the 1550nm ones shown above with "ko"). The 1610nm ones apparently are ok, they have been tested using a traffic generator. The leased line has also been tested more than once. All is within tolerances. I'm awaiting the replacements but for some reason I don't believe it will make things better as the apparently good ones don't produce ZERO errors either. Earlier there was active equipment involved (some kind of 4GFC retimer) before putting the signal on the line. No idea why. That equipment was eliminated because of the problems so we now only have: the long distance laser in the switch, (new) 10m LC-SC monomode cable to the mux (for each fabric), the leased line, the same thing but reversed on the other side of the link. FC switches Here is a port config from the Brocade portcfgshow (it's like that on both sides, obviously) Area Number: 0 Speed Level: 4G Fill Word(On Active) 0(Idle-Idle) Fill Word(Current) 0(Idle-Idle) AL_PA Offset 13: OFF Trunk Port ON Long Distance LS VC Link Init OFF Desired Distance 32 Km Reserved Buffers 70 Locked L_Port OFF Locked G_Port OFF Disabled E_Port OFF Locked E_Port OFF ISL R_RDY Mode OFF RSCN Suppressed OFF Persistent Disable OFF LOS TOV enable OFF NPIV capability ON QOS E_Port OFF Port Auto Disable: OFF Rate Limit OFF EX Port OFF Mirror Port OFF Credit Recovery ON F_Port Buffers OFF Fault Delay: 0(R_A_TOV) NPIV PP Limit: 126 CSCTL mode: OFF Forcing the links to 2GbFC produces no errors, but we bought 4GbFC and we want 4GbFC. I don't know where to look anymore. Any ideas what to try next or how to proceed? If we can't make 4GbFC work reliably I wonder what the people working with 8 or 16 do... I don't assume that "a few errors here and there" are acceptable. Oh and BTW we are in contact with everyone of the manufacturers (FC switch, MUX, SFPs, ...) Except for the SFPs to be changed (some have been changed before) nobody has a clue. Brocade SAN Health says the fabric is ok. MUX, well, it's passive, it's only a prism, nature at it's best. Any shots in the dark? APPENDIX: Answers to your questions @Chopper3: This is the second generation of Brocades exhibiting the problem. Before we had 5000s, now we have 5100s. In the beginning when we still had the active MUX we rented a longdistance laser once to put it into the switch directly in order to make tests for a day, during that day of course it was clean. But as I said, sometimes it's clean just like that. And sometimes it's not. Alternative switches would mean to rebuild the entire SAN with those only to test. Alternative SFPs, well they're hard to come by just like that. @longneck: The line is rented. It's a dark fibre (9um monomode) so there's noone else on it. Sure there are splices. I can't go and look but I have to trust they have been done correctly. As I said the line has been checked and rechecked (using an optical time-domain reflectometer). Obviously you don't have all this equipment yourself because it's way too expensive. @mdpc: What would be the "wrong" type of cable according to you? Up to the switch everything is monomode, yes. The connectors are the correct ones too. Yeah I know there are the green ones where the fibre is cut off at a certain angle etc. But we have the correct ones for all that I know. Progress Report #1 We have had two fabrics (=2x2 switches) with Brocade 5100s with FabricOS 6.4.1 and two fabrics (another 2x4 switches) on FabricOS 7.0.2. On the longdistance ISLs (one in each fabric) it turned out that with FOS 6.4.1 setting it to long distance issues warnings about the VC Init setting and consequently the fill word. But those are only warnings. FOS 7.0.2 requires you to do modifications to VCI and the fillword for long distance links. Setting FOS 6.4.1 to the LS (long-distance static distance) setting with wrong VCI and fillword setting made the whole fabric inoperational (stuck in an SCN loop, use fabriclog -s to see, you don't see it anywhere else, no port error counters or anything increasing). Currently I'm giving the one fabric with the IMHO more correct settings a beating and it seems to do fine, whereas the other one without much traffic still has errors here and there. In short: We have eliminated the active part of the MUX (the FC retimer). We are putting the long distance SFPs into the end equipment themselves. Just to be sure we bought new monomode cables to connect the end equipment to the remaining passive part of the MUX. We are now trying out several long distance configs. It's almost black magic. Everything that happens is mostly empirical, noone seems to have a clue what are the exact reasons to do something. ("We have tried this, and it didn't work, then we tried that and it worked, so we stuck with that." But noone really seems to know why.) I'll keep you updated. Progress Report #2 We got the new lasers for one of the fabrics on warranty. It's ultra clean even on 4GbFC. They're transmitting with roughly 2mW (3dBm) whereas the others are only at 1.5mW (1.5dBm) although that should really be enough. The other fabric (where the lasers are apparently ok) still produces one or two CRCs infrequently. Using sfpshow the SFP producing the actual RX errors shows Status/Ctrl: 0x82 Alarm flags[0,1] = 0x5, 0x40 Warn Flags[0,1] = 0x5, 0x40 Now I'll have to find out what that means. Not sure if it was there before. Well I'll first clear my head with a week of vacation. 8-)

  • Problems with testing in app purchases

    - by sashaeve
    I am trying to test my application with in app purchases. I created features, test user, logged out from iTunes on the iPhone and used developer certificate. Load app from XCode in debug mode. When I click "Buy" button I pass all checks for internet availability, canMakePayments and call SKPayment *payment = [SKPayment paymentWithProductIdentifier:featureId]; [[SKPaymentQueue defaultQueue] addPayment:payment]; But all what I see is a pending view and after some minutes it failed in - (void) failedTransaction: (SKPaymentTransaction *)transaction { if (transaction.error.code != SKErrorPaymentCancelled) { NSLog(@"failedTransaction"); } [[MKStoreManager sharedManager] paymentCanceled]; [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; } Please advice in what direction I should go to figure out the problem and what else I should check. P.S. All related questions on SO were checked with no luck.

  • How can I find out which version of emacs introduced a function?

    - by Chris R
    I want to write a .emacs that uses as much of the mainline emacs functionality as possible, falling back gracefully when run under previous versions. I've found through trial and error some functions that didn't exist, for example, in emacs 22 but now do in emacs 23 on the rare occasion that I've ended up running my dotfiles under emacs 22. However, I'd like to take a more proactive approach to this, and have subsets of my dotfiles that only take effect when version = <some-threshold> (for example). The function I'm focusing on right now is scroll-bar-mode but I'd like a general solution. I have not seen a consistent source for this info; I've checked the gnu.org online docs, the function code itself, and so far nothing. How can I determine this, without keeping every version of emacs I want to support kicking around?

  • In Android Browser link does not always execute onClick causing focus instead

    - by Artem
    I am trying to program a very standard JS behavior for a link using an HREF onClick handler, and I am facing a strange problem caused by what I believe to be focus/touch mode behavior on Android. Sometimes when I click on the link, instead of executing the action, it simply becomes selected/focused, with either just a focus rectangle or even also with a filled focus rectangle (selected as opposed to just focused?). The pseudo-code right now is <a href="#" onClick="toggleDivBelowToShowHide(); return false;">go</a> I have tried doing something like: <a href="#" onTouchStart="toggleDivBelowToShowHide(); return false;">go</a> But I still get the same pesky problem some of the time.

  • NSTimer to fire while device is locked

    - by edie
    Hi, I'm currently creating an alarm. I use NSTimer to schedule my alarms. My problem is when the device was put into locked mode my NSTimer doesn't fire. I think that the NSTimer will not fire because my app goes to suspended state when it is lock. Can you help me find a solution to my problem? I've found some topics about UIBackgroundModes, but I don't know how it will help me. Thanks.. The problem in UILocalNotification is when the device was in silent, the sound will not be hear. My implementation was I'm using NSTimer to fire an alarm when the app is in foreground or device is locked but app currently running. When the applicationDidEnterBackground: is called I schedule the UILocalNotification as the alarm.

  • VS2010 Clean Web.configs - not updating

    - by cw
    Hello, I'm messing around with MVC 2.0 on VS2010 and am having an issue getting the clean web config feature working. Basically in my Web.debug.config I have <connectionStrings xdt:Transform="Replace"> <add name="ApplicationServices" connectionString="Server=localhost;Database=SITE_DB;User ID=dbuser;Password=P@ssw0rd;Trusted_Connection=False;" /> </connectionStrings> and in my Web.config I have <connectionStrings> <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" /> </connectionStrings> When I run the site in debug mode, I'd expect that xdt:Transform="Replace" would replace the entire connectionStrings section with what is in the Web.debug.config. Am I assuming wrong? Or am I doing something else incorrect. Not much info posted around this and I'd figure I'd ask you guys.

  • Cure for puzzle piece programming habits?

    - by Recursion
    Even though I went to a decent CS school, I was still taught with the mentality of programming with puzzle pieces. By puzzle pieces I mean, looking up code segments at each step of the development process and adding them together as needed. Eventually gathering all of the pieces and having a properly working program. So as an example, if in my program the next step is to tokenize a string, I go to google and search "how do I tokenize a string in language". All instead of critically thinking about its implementation. I personally don't think its a very good way to program and I always seem to forget everything that I have searched for. So how can I get out of this puzzle piece mode of programmer that I was taught.

  • Log4cxx sample program and steps to compile

    - by Jake
    Hi guys Hoping someone can help out.. I've been scouring the net for a simple how-to to get a good log4cxx program working, with steps on setting up the libraries, dependants, directives, library paths etc etc.. as of yet i've found a lot of valuable but disjointed information.. trying to pull it all together has been a bit of a nightmare, so i'm reaching out and wondering if any kind soul knows of, or could put together a simple how-to, to get a standard win32 console app running with either static or dynamically linked release mode log4cxx.. I have win32 binary releases of the libraries, and thanks to a very cool dude from "Must a blog have a name" I have a win32 project which can build log4cxx.. i just cant bloody use it :) It would be really helpful to me, and probably to others, to be able to refer to something like this and not 20 different pages, with different lists of libraries needed to download and install.. :) Here's hoping Thanks guys J

  • How to debug a GWT application running on OSGi?

    - by Jaime Soriano
    I'm developing a web UI using GWT. While working only with the widgets I could debug from Eclipse using the Firefox extension, but now that I'm integrating the UI with other OSGi bundles I cannot use this solution. For deploying the GWT application I create the .war and convert it to an OSGi bundle using BND. Then I launch the OSGi container with all the bundles using Pax Runner and Pax Web and the application works correctly, but when something fails in the generated javascript code I don't have any decent output error or debugging facility. Is there any way to launch the GWT application in "debug mode" from OSGi? Any other idea that could help in this scenario?

  • UIView Clipped By Statusbar until Autorotate

    - by TonyNeallon
    Hi There, Ive created a multiview application that uses multiple controllers to display and control views. The problem Im having is, when the simulator initially loads the view the header is partially covered by the bar at top of screen and the tool bar at the base is not touching the base of the screen. I used the Interface builder size attributes to control the view when the iphone rotates and it works perfectly. All smaps into place perfectly both in landscape and portrait mode AFTER a rotation but the problem is with the initial load before a rotation occurs. Your thoughts a much appreciated. Tony

  • Getting "Object is read only" error when setting ClientCredentials in WCF

  • Web Service in c# - "This web service is using http://tempuri.org/ as its default namespace."

    - by glenatron
    I've created a web service using Visual Studio ( 2005 - I know I'm old school ) and it all compiles fine but when it opens I get warned thus: This web service does not conform to WS-I Basic Profile v1.1. And furthermore: This web service is using http://tempuri.org/ as its default namespace. Which would be fine except my service begins thus: [WebService(Namespace = "http://totally-not-default-uri.com/servicename")] Searching the entire solution folder for "tempuri" returns nothing. I can't find it mentioned in any configuration page acessible from Visual Studio. And yet it's right there in the wsdl:definitions list for the xmlns:tns attribute on the web service descriptor page when I view it through the browser and as targetNamespace in the same tag. I'm viewing it using Visual Studio's "debug" mode with the built in server from that. Seems like something has got cached somewhere but I can't work out what and where- I've tried stopping and restarting the server, cleaning and rebuilding the service and going through the associated text config files with a text editor but no dice. Any idea what is going on?

  • I have some questions about building an AIR app for use with a connected projector.

    - by knuckfubuck
    For an app I'm working on, I'd like to have a control panel window and a video output window to use for projecting video with an attached projector. I have built many Flash applications but this will be my first time using AIR so I have some questions. Is it possible to have two seperate windows as part of one AIR application? Can one of the windows (the video output) be in full-screen mode while the other window stays normal? How does AIR do with playing local video? Will there be crashes or choppy playback? Is there a better language option for what I'm trying to accomplish?

  • creating a Menu from SQLite values in Java

    - by shanahobo86
    I am trying to create a ListMenu using data from an SQLite database to define the name of each MenuItem. So in a class called menu.java I have defined the array String classes [] = {}; which should hold each menu item name. In a DBAdapter class I created a function so the user can insert info to a table (This all works fine btw). public long insertContact(String name, String code, String location, String comments, int days, int start, int end, String type) { ContentValues initialValues = new ContentValues(); initialValues.put(KEY_NAME, name); initialValues.put(KEY_CODE, code); initialValues.put(KEY_LOCATION, location); initialValues.put(KEY_COMMENTS, comments); initialValues.put(KEY_DAYS, days); initialValues.put(KEY_START, start); initialValues.put(KEY_END, end); initialValues.put(KEY_TYPE, type); return db.insert(DATABASE_TABLE, null, initialValues); } It would be the Strings inserted into KEY_NAME that I need to populate that String array with. Does anyone know if this is possible? Thanks so much for the help guys. If I implement that function by Sam/Mango the program crashes, am I using it incorrectly or is the error due to the unknown size of the array? DBAdapter db = new DBAdapter(this); String classes [] = db.getClasses(); edit: I should mention that if I manually define the array: String classes [] = {"test1", "test2", "test3", etc}; It works fine. The error is a NullPointerException Here's the logcat (sorry about the formatting).

  • T-SQL Picking up active IDs from a comma seperated IDs list

    - by hammayo
    I have two tables "Product" having following structure: ProductID,ProductName, IsSaleTypeA, IsSaleTypeB, IsSaleTypeC 1, AAA, N, N, N 2, BBB, N, Y, N -- active 3, CCC, N, N, N 4, DDD, Y, N, N -- active 5, EEE, N, N, N 6, FFF, N, N, N 7, FFE, N, N, N 8, GGG, N, N, N 9, HHH, Y, N, N -- active The second table "ProductAllowed" having following structure where ProductIDs is a comma separated string filed having mix of active and inactive product ids based on their IsSaleType mode. ProductCode, ProductIDs AMRLSPN, "1,2" AMRLOFD, "1,3" BLGHVF, "2,4,6" BLGHVO, "2,4" BLGHVD, "3,5" BLGSDO, "0" CHOHVF, "1,6" CHOHVP, "1,2,7,8" ... ... Q: Is there a t-sql query that will return a list of active records from the "ProductAllowed" table if any of three IsSaleType fileds is/are switched on for a product. Based on the sample data the ProductAllowed records should return following records. AMRLSPN BLGHVF BLGHVO BLGSDO CHOHVP This needs to be applied in a SQLSERVER 2000 database containing aprox 150000 records. Thanks
