  • Strangling the life out of Software Testing

    - by MarkPearl
    I recently did a course at the local university on Software Engineering. At the beginning of the course I looked over the outline of the subject and there seemed to be some really good content. It covered traditional & agile project methodologies, some general communication and modelling chapters and finished off with testing. I was particularly excited to see the section on testing as this was something I learnt on my own and see great value in. The course has now just ended and I am very disappointed. I now know one of the reasons why so few people i.e. in my region do Test Driven Development, or perform even basic testing methodologies. The topic was to academic! Yes, you might be able to list 4 different types of black box test approaches vs. white box test approaches and describe the characteristics of Smoke Tests, but never during course did we see an example of an actual test or how it might be implemented! In fact, if I did not have personal experience of applying testing in actual projects, I wouldn’t even know what a unit test looked like. Now, what worries me is the following… It took us 6 months to cover the course material, other students more than likely came out of that course with little appreciation of the subject – in fact they now have a very complex view of what a test is – so complex that I think most of them will never attempt it again on their own. Secondly, imagine studying to be a dentist without ever actually seeing a tooth? Yes, you might be able to describe a tooth, and know what it is made out of – but nobody would want a dentist who has never seen a tooth to operate on them. Yet somehow we expect people studying software engineering to do the same? This is not right. Now, before I finish my rant let me say that I know this is not the same everywhere in the world, and that there needs to be a balance on practical implementation and academic understanding – I am just disappointed that this does not seem to be happening at the institution that I am currently studying at ;-( Please, if you happen to be a lecturer or teacher reading this post – a combination of theory and practical's goes a long way. We need to up the quality of software being produced and that starts at learner level!

  • Protobuf design patterns

    - by Monster Truck
    I am evaluating Google Protocol Buffers for a Java based service (but am expecting language agnostic patterns). I have two questions: The first is a broad general question: What patterns are we seeing people use? Said patterns being related to class organization (e.g., messages per .proto file, packaging, and distribution) and message definition (e.g., repeated fields vs. repeated encapsulated fields*) etc. There is very little information of this sort on the Google Protobuf Help pages and public blogs while there is a ton of information for established protocols such as XML. I also have specific questions over the following two different patterns: Represent messages in .proto files, package them as a separate jar, and ship it to target consumers of the service --which is basically the default approach I guess. Do the same but also include hand crafted wrappers (not sub-classes!) around each message that implement a contract supporting at least these two methods (T is the wrapper class, V is the message class (using generics but simplified syntax for brevity): public V toProtobufMessage() { V.Builder builder = V.newBuilder(); for (Item item : getItemList()) { builder.addItem(item); } return builder.setAmountPayable(getAmountPayable()). setShippingAddress(getShippingAddress()). build(); } public static T fromProtobufMessage(V message_) { return new T(message_.getShippingAddress(), message_.getItemList(), message_.getAmountPayable()); } One advantage I see with (2) is that I can hide away the complexities introduced by V.newBuilder().addField().build() and add some meaningful methods such as isOpenForTrade() or isAddressInFreeDeliveryZone() etc. in my wrappers. The second advantage I see with (2) is that my clients deal with immutable objects (something I can enforce in the wrapper class). One disadvantage I see with (2) is that I duplicate code and have to sync up my wrapper classes with .proto files. Does anyone have better techniques or further critiques on any of the two approaches? *By encapsulating a repeated field I mean messages such as this one: message ItemList { repeated item = 1; } message CustomerInvoice { required ShippingAddress address = 1; required ItemList = 2; required double amountPayable = 3; } instead of messages such as this one: message CustomerInvoice { required ShippingAddress address = 1; repeated Item item = 2; required double amountPayable = 3; } I like the latter but am happy to hear arguments against it.

  • database independent coding framework options?

    - by statirasystems
    Background: I have not programmed in a while besides doing VBA and a little VB.NET. So please forgive my language use. I'm green and have a head cold. I am reading all I can now, but I have no programming circles to draw from. The information I am providing is to help guide you to what I am looking for. I am not confident I can ask the question properly. Story: I have four different projects that I am starting. Obviously I won't be working on all at the same time however they each will have similar needs and be inter related. They are as follows: Desktop Environment/System User Interface - basically a product that runs on major computers via mono or .net that unifies the look and functions. In the context of the up coming question it would be able to directly access data of various types. It would work in tandum with my office suite, system manager, and network application framework. Office Suite - technically it would not be a suite since I will be doing it from one interfacel except for the Communications Application. As far as the question, it will need to be able to link to various data sources for storing files and using, manipulating, and presenting information. System Manager - an intellegent system to manage and administer the entire network and all equipment. As far as the question, needs to be able to access data for archiving and and for accessing it's own settings stored in various formats, sql or xml. Network Application Framework - A complete system that can be used for ERP, CRM, CMS, Errata, File Management, and so on. As to the question to be able to access it's own or interlink with existing applications. Requirement: C#, Simplifies and reduces coding, use the same code to access diffent databases(ie MySQL, MS SQL, ACCESS, XML, ...), Mono would be nice but not a must, Question: What librarys, frameworks, or other options would be able to help with this? Is there a good resource to guide me? I don't want arguing over what is best, just information to help me further understand and make an educated decision.

  • Want to make RTS strategy game, good starting point...?

    - by NOLANDI
    everybody! I find this community because I did research about game developing topics. So I decide to register on this community and ask for your opinion. I am not begineer in computer stuffs, and I know logic of programming language. I have little knowlegde of C, C++, Started to learn C#...but I was always oriented about other areas of IT. Amateur for game making but not in IT general! I am interested to make RTS strategy video game, isometric camera view (like PC GAME COMMANDOS for example)...so I started to read many books about DirectX, XNA, OpenGL, C#, AI programming...so I want to know where is good starting point for making this game genre. I want to use C# for this project, not C++, since I always had trouble with it, because it is too complicated. I see good oportunity for learning C#, since it has more object-oriented concept, with much less code and easy readible code for writing. Beside of that I know that C++ is the more powerful language until today. So I want to use DirectX and C# for my project. But it will required more time for sure, to learn it. I have trouble with finding books for c# & DirectX (I found just one), but in every next book, it is programming in c++! I read many web sites and they mentioned Slim DX, and in generaly, other articles which I read tells that it is possible to make good game with combination c# and directX, but...I don't have enough information about all this stuffs, so I became confused! It is really hard to have wish to learn c++ from scratch, since I started c# and I like it really...I don't try OpenGL, but I am already familiar with DirectX (some beginning stuffs), and I think that it is good and interesting. So, I decide to choose between maybe Unity3d and XNA first. XNA...hm, it sound that it is not bad solution, but I heard that it is already overcome technology, and I think that it is better to wait with XNA, until I try to make something with DirectX and C#, at first. But I dont know it is possible to make strategy game in XNA?! Maybe I am wrong. I also, find Unity 3D game engine and I find that I could programming there in C#, but many all examples are written in Javascript (Digital tutors videos)...But I generaly have wish to learn it too, because it allows to export games to mobile phones, there a lot of documentations, it is free, etc... I want to find best way to learn C# and DirectX, and make this game, but I dont know if it's possible to combine?! But maybe is good to first try Unity and XNA, because I am beginner?! Thank you all! I am willing to hear your expirience.

  • JQuery Validation [migrated]

    - by user41354
    Im trying to get my form to validate...so basically its working, but a little bit too well, I have two text boxes, one is a start date, the other an end date in the format of mm/dd/yyyy if the start date is greater than the end date...there is an error if the end date is less than the start date...there is an error if the start date is less than today's date...there is an error The only thing is when I correct the error, the error warning is still there...here is my code: dates.change(function () { var testDate = $(this).val(); var otherDate = dates.not(this).val(); var now = new Date(); now.setHours(0, 0, 0, 0); // Pass Dates if (testDate != '' && new Date(testDate) < now) { addError($(this)); $('.flightDateError').text('* Dates cannot be earlier than today.'); isValid = false; return; } // Required Text if ($(this).hasClass("FromCal") && testDate == '') { addError($(this)); $('.flightDateError').text('* Required'); isValid = false; return; } // Validate Date if (!isValidDate(testDate)) { // $(this).addClass('validation_error_input'); addError($(this)); $('.flightDateError').text('* Invalid Date'); isValid = false; return; } else { // $(this).removeClass('validation_error_input'); removeError($(this)); if (!dates.not(this).hasClass('validation_error_input')) $('.flightDateError').text(' '); } // Validate Date Ranges if ($(this).val() != '' && dates.not(this).val != '') { if ($(this).hasClass("FromCal")) { if (new Date(testDate) > new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* Start date must be earlier than end date.'); isValid = false; return; } } else{ if (new Date(testDate) < new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* End date must be later than start date.'); return; } } } }); The main Issue is this part, I believe // Validate Date Ranges if ($(this).val() != '' && dates.not(this).val != '') { if ($(this).hasClass("FromCal")) { if (new Date(testDate) > new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* Start date must be earlier than end date.'); isValid = false; return; } } else{ if (new Date(testDate) < new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* End date must be later than start date.'); return; } } } testDate is the start date otherDate is the end date Thanks in advanced, J

  • What exactly is a X-YMailISG header?

    - by iainH
    Finally ... our emails are being seen by Yahoo! not as junk anymore. Hurray! However I notice that the Yahoo! receiving MTA adds in a X-YMailISG header. It's very large ... 2**10 bits? Now that I've invested too large a chunk of my waking life in crafting our email headers I'm curious to know what an X-YMailISG header is. Can anybody tell me? Does it pose any security / authenticity issues? There's very little intelligible from Google results. Background: After many days tweaking TXT records in our domain's DNS zone file for SPF and DKIM, I have at last succeeded in generating email from our Drupal site that Yahoo! no longer marks as X-YahooFilteredBulk and the excellent service [email protected] returns results that show the emails passing SPF, DKIM and Sender-ID checks and appearing to SpamAssassin as ham. Yahoo! even adds a Received-SPF: pass header. Useful links: http://www.goldfisch.at/knowwiki/howtos/dkim-filter http://old.openspf.org/wizard.html Strangely enough the SPF TXT record needed / allowed a blank key / name field in our registrar's DNS management panel whereas the DKIM record needed the {selector}._domainkey as the key /name of the DKIM strings.

  • Access to message queuing system is denied MSMQ?

    - by user1401694
    My problem is a little confusing. I have 2 servers (Windows Server 2008 R2) with MSMQ installed and I want to use Server B to consume a MessageQueue on Server A. When I try to Receive it always throws a message error: "Access to message queuing system is denied.". IP between them. Server A: 172.31.23.130 Server B: 172.31.23.195 FormatName:Direct=TCP:172.31.23.195\private$\queuesource (It's working for Sends) I can ping each server from the other; The firewall is disabled; The "queuesource" has Full Control to "Everyone", "Anonymous Logon", "Network", "Network Services"; Journal is disabled; Authentication is ok; The queue is Transactional. My code in .Net C# is basically like this: MessageQueue _sourceQueue = new MessageQueue(); _sourceQueue.Path = "FormatName:Direct=TCP:172.31.23.195\private$\queuesource"; _sourceQueue.Receive(); // << here throw an exception. Actually I'm using the Private Queue only to avoid Active Directory's problems. For example, if the server DNS fail all network fail. I don't know what do anymore.

  • Kodak Scanner Software Issue 0xc0000005

    - by Andrew
    I am trying to be able to use a program called Kodak Smart Touch, but just today I have experienced an error preventing it from opening. The scanner is a business class scanner, an i2900. It comes with a small program called Kodak Smart Touch. This program allows you to select and customize a number of presets on the front panel and automatically create/save scanned files, etc. I was running a backup with Aomei Backupper at the time, and I wanted to scan a file. I tried to scan as normal, but right at the end the program quit with an error. Now, whenever I try to start Smart Touch, even not running the backup and with Aomei uninstalled, the following error pops up: Title of message: KSSCFG (version 1.7.15.121102) has stopped working. Body: See (path name) for more information. When I go to the path in the error message, there are two files, ERRORLOG.txt and KSSCFG.dmp. The error log says, "KSSCFG (version 1.7.15.322.121102) case an Access Violation(0xc0000005). Error occur at 2014/06/11 21:37:54 Operation System: Windows 7 64bits (6.1.7601) processor(s) type AMD x86 or x64" The dump file can be downloaded here: http://l.bitcasa.com/yzbtv1VV Opening it with a hex editor yields very little of use, but I do have an internal commandline utility that may help: http://l.bitcasa.com/cTXvAsst I've already uninstalled and reinstalled all the kodak software several times to no avail. What is really odd is that the TWAIN and ISIS drivers work fine through another scanning program. I am at my wit's end, and I have no idea what to do next. Thanks.

  • multiple monitor, ATI EyeFinity vs NVidia Mosaic on HDMI

    - by user1531897
    i have been googling much for answer but only someone with real experience can help here. my aim is to have 5 monitors connected to one computer in 2x2 full screen on all 4 monitors (video wall) with same resolution, 4xfullHD for example, plus one -5th monitor as controling. Ati have example picture of this configuration here. I have no gaming nor 3d needs here. Simple desktop applications plus video streams. So because graphic cards for this are expensive, i need to find out before buying pros and cons of 2 possible solutions (1) Ati Eyefinity capable card(s) ...and (2) Nvidia Quadro/NVS card(s) with mosaic and/or nvidia surround technology. For example i can find that current good cards for this can be: Ati's 7870 eyefinity6 card, link here pros: one card can handle all 5 displays, cons: active DP adapters needed (sometimes with aditional usb-powering complication) Nvidia Qudro NVS 450, link here Both cards have DisplayPorts as outputs (my targets are HDMI displays), but as far i saw information is that Eyefinity needs "active DP-DVI/hdmi adapters" for outputs and they are little expensive...? Does nvidia have this limitation (active adapters) ??? And final question, is Ati Eyefinity still better for this purpose than Nvidia-mosaic by someone's real experience there.

  • Using Nortel Netdirect on Windows 7 64bit

    - by Matt Lewis
    Does anyone know how to use Nortel Netdirect (Version 7.1.3.0) with Windows 7 64 bit (Home Premium)? There are several ways available to me for connecting, all of which work for me on a 32-bit XP machine: Nortel Contivity VPN client (v6_02.022). The installer appears to be 16-bit, so I can't even install it on a 64-bit machine. Web-based SSL via IE Web-based SSL via Firefox The Web-based SSL process is supposed to load Netdirect and start it up, establishing the VPN connection. Using Firefox, I'm able to authenticate with my smartcard, but when it tries to download the applet, the process stops with a message box saying that it couldn't download the zip file. If I run Firefox in Vista compatibility mode, it gets a little farther, and manages to start Netdirect, but then exits after notifying me that the netdirect adapter was not installed. Using IE, I'm able to authenticate with my smartcard, then the java applet starts, but dies with the following sent to the java console: load: class NetDirect not found. java.lang.ClassNotFoundException: NetDirect at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: javax.net.ssl.SSLHandshakeException: Received fatal alert: unknown_ca at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown Source) at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.recvAlert(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readRecord(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.performInitialHandshake(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(Unknown Source) at sun.net.www.protocol.https.HttpsClient.afterConnect(Unknown Source) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getResponseCode(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Exception: java.lang.ClassNotFoundException: NetDirect I've tried installing certificates using java's keytool, but that didn't change the outcome.

  • CodeIgniter's index.php

    - by 01010011
    Hi, Following CodeIngiter's installation instructions, I extracted CodeIgniter into XAMPP's htdocs folder and placed its index.php at the root. When I navigated to the following url h t t p://127.0.0.1/index.php I got the following error messages: Warning: require_once(C:\xampp\htdocs/system/codeigniter/CodeIgniter.php) [function.require-once]: failed to open stream: No such file or directory in C:\xampp\htdocs\index.php on line 115 Fatal error: require_once() [function.require]: Failed opening required 'C:\xampp\htdocs/system/codeigniter/CodeIgniter.php' (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\index.php on line 115 When I checked line 115 in the index.php, it stated: require_once BASEPATH.'codeigniter/CodeIgniter'.EXT; Experimenting a little, I put CodeIniter's "system" folder at the root as well, and it worked, providing me access to CodeIgniter's Welcome page, but the instructions did not say to do this. Experimenting further, when I put back the "system" folder and navigated to the original place where the index.php h t t p://127.0.0.1/codeigniter_1.7.2/index.php it worked. But myquestion is, how do I get to the CodeIgniter's welcome page by placing only the index.php in XAMPP's htdocs as instructed by CodeIgniter? Any assistance will be appreciated.

  • Windows Server 2008 / SQL 2008 Licensing for Authenticated Web Application

    - by MikeM
    Hello, I'm trying to crunch some numbers to see what the software costs involved are for hosting an application we are developing. Users will not be anonymous - they will need to log in. SQL Server 2008: SQL Server licensing is easy - it will be licensed per-processor. No real fuss there. The cost of CALs would be much higher for the number of users as compared to the processor licenses. Windows Server 2008: This is where it gets trickier. We need to license the OS for both the web servers (there will be a couple) plus the database servers (also a couple). The Web Servers could run on the Web Edition without a need for CALs, but if you continue reading, you will see that may not matter much because I will likely have user CALs for each user anyway. We can't use the "External Connector" for any of the Windows licenses, because that doesn't cover customers who are paying to access a hosted application. We can't use the Web Edition for the SQL Servers because that license only allows database running on Web Edition to host data for the local web application (i.e. other web servers can't connect to it). So that leaves us with the "full" editions of Windows Server for the database server OS. I find this a little rediculous, and I feel as though I must be missing something, but it looks to me like I will actually need to buy a CAL for every user who signs up to use our service. I feel like I'm missing something because that means that for every user, I have to shell out $40 for a CAL. That could be one or two years' worth of revenue from each user for an inexpensive service! Is there any way to serve a web application to authenticated users without paying for individual Windows Server CALs, if the web servers and SQL servers are seperate boxes?

  • Telnet does not give a response

    - by floorish
    Some wireless access points are acting a little weird, so I want to reboot them every couple of hours. Luckily there exists a security flaw which lets me login as root through telnet when using port 1111 (without username and password). Now I want to use that to let my QNAP NAS execute the reboot command through telnet every now and then. The problem is however that that telnet version doesn't give any response if I connect to the AP. The telnet I use on OSX works just fine but the one on the NAS not. BusyBox v1.01 (2012.06.14-18:35+0000) multi-call binary Usage: telnet [-a] [-l USER] HOST [PORT] When I execute telnet <HOST> 1111 nothing happens. I can send the escape character ^] which gives me the following options: Console escape. Commands are: l go to line mode c go to character mode z suspend telnet e exit telnet The only way to get some commands executed is by suspending telnet with z followed by some random command which isn't recognized. Then the prompt shows this: # telnet 192.168.1.5 1111 ^] Console escape. Commands are: l go to line mode c go to character mode z suspend telnet e exit telnet z continuing... asdf Illegal command. 00> After that I am able to communicate with the AP, but when I exit the telnet session and try the same again, the AP refuses to connect at all and it must be manually rebooted (looks like the telnet session isn't shut down properly on the AP). So the question is what commands should I execute in order to communicate with the AP using the Busybox telnet version of the QNAP? (No, can't use ssh unfortunately)

  • Mac OS X Server (10.5) mail trapped in queue

    - by Meltemi
    We've got mail accumulating in our Leopard Server's queue and not sure exactly why. This machine has required little maintenance over the years so I'm hoping someone here spot the obvious and save us some time. Let me know what other information would be helfull. Server appears to be functioning normally except for "clogged" queue and the following error associated with each "trapped" message: Looking at messages in the queue each one states something like this: Message ID: 4213C3B8B3F Date: October 27, 2009 11:33:27 AM Size: 1824 Sender: [email protected] Recipient(s) & Status: ---------------------- [email protected]: connect to 127.0.0.1[127.0.0.1]: Connection refused Under SettingsRelay we have checked Accept SMTP relays only from these hosts and networks: 127.0.0.0/8 10.0.1.0/24 The mail in queue is addressed to users whose accounts are on this server. Mail.app on the client appears to be functioning normally and checking checking mail on the server. We did add a virtual domain some time ago but all that was working fine for some time... This just started happening recently...any ideas? Edit: toggling the filter services on and off seems to have fixed this except for 2 remaining queued messages that show "mail transport unavailable" as an error!?!

  • postfix + opendkim not signing correctly. how to debug this?

    - by Dean Hiller
    EDIT: I did get a little further but all posts on my search say permissions are wrong or regenerate key but I fixed that to be 644 as well as owned by DKIM AND I keep regenerating the key but it is not helping. My latest error now is this Apr 21 21:19:12 Sniffy opendkim[8729]: BB5BF3AA66: dkim_eom(): resource unavailable: d2i_PrivateKey_bio() failed Apr 21 21:19:12 Sniffy postfix/cleanup[8627]: BB5BF3AA66: milter-reject: END-OF-MESSAGE from localhost[127.0.0.1]: 4.7.0 resource unavailable; from=<[email protected]> to=<[email protected]> proto=SMTP helo=<abcs.com> I am looking for a way to simply debug this(don't necessarily need the answer but a way to get logs from opendkim would be good). If I stop opendkim, I see postfix log connection refused which is good. but when I send mail with opendkim started, I see no logs whatsoever. I even add the "LogWhy Yes" line to my opendkim.conf file as well and still see no logs there. Since I see opendkim running under user opendkim, I changed the owner of /etc/opendkim/* and /etc/opendkim and /etc/opendkim.conf all to opendkim user. I am running on ubuntu.

  • "No more threads can be created in the system" in Network and Sharing Center

    - by Zell Faze
    A while back I noticed on one of our laboratory computers (Windows 7, very little extra software installed) that the network connection icon in the system tray would claim that it had no network connection, even though it did. This issue would go away after the computer was rebooted, but would surface again the next time I looked at the computer (a few days later). Upon opening the Network and Sharing Center I am shown an actual error message, but not one that seems to give me a lot of information about what the problem is. In the place of the usual information about network adapters and whether you are connected to the Internet it simply says: "No more threads can be created in the system." The Event Viewer shows hundreds of events from different services also with the same message. "Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance. hr = 0x800700a4, No more threads can be created in the system."; "The WinHTTP Web Proxy Auto-Discovery Service service failed to start due to the following error: A thread could not be created for the service."; "The IP Helper service terminated with the following error: No more threads can be created in the system." As far as I can tell, this message seems to mean that there is some sort of resource leak in Windows where something is creating a large number of threads and those threads are not being killed off? I've tried restarting WMI and several services related to networking, without avail. Can anyone provide more information on what "No more threads can be created in the system" might mean and what I might be able to do to fix the issue? Currently the only solution appears to be restarting.

  • Windows 8 and SMB2 Issues

    - by Rhys Paterson
    We're playing with the consumer preview of Windows 8 and having issues accessing some network shares in our environment. Basically, when I attempt to access a share directly (\[SERVER].[DOMAIN].[NETWORK]\Share$) I get 'An extended error has occured'. The shares reside on an EMC Celerra system. Sorry, I don't really have much more information about it (this is just a little side project). Accessing shares that reside on Windows machines are fine. The Firewall is completley disabled and I am running under full domain administrative credentials. A quick wireshark shows the following group of packets between myself and the server: SMB2 164 NegotiateProtocol Request SMB2 274 NegotiateProtocol Response SMB2 981 SessionSetup Request SMB2 281 SessionSetup Response SMB2 200 TreeConnect Request Tree: \\[SERVER].[DOMAIN].[NETWORK]\[SHARE]$ SMB2 138 TreeConnect Response SMB2 202 Ioctl Request NETWORK_FILE_SYSTEM Function:0x0080 SMB2 131 Ioctl Response, Error: STATUS_INVALID_DEVICE_REQUEST SMB2 126 SessionLogoff Request SMB2 126 SessionLogoff Respons This repeats five times and then (I assume) Windows throws me the above error. A quick Google shows me: 0xC0000010 STATUS_INVALID_DEVICE_REQUEST The specified request is not a valid operation for the target device. Which shows me that NETWORK_FILE_SYSTEM Function:0x0080 request is invalid.. Does anyone know what would cause this? Thanks in advance. Rhys. Edit: FYI - as a workaround, you can disable SMB 2.2 as noted in the EMC thread: sc config lanmanworkstation depend= bowser/mrxsmb10/nsi sc config mrxsmb20 start= disabled This will allow the machine to access the shares. The below answer still stands though :)

  • swapping or trashing with vast amounts of unmapped pagecache

    - by Marco
    I'm using kubuntu jaunty (i386 32bit), kernel 2.6.28-13-generic. I've 4Gb of RAM, of which only 3317Mb are seen by the system (I guess because of the 32bit system). I'm seeing that the pagecache utilization is continually growing, up to the point that the system is unusable (after a few days). This happens also when I don't do anything (all user applications closed and the bare minimum of services enabled). If enabled, the system starts to use swap space (using it all in the end). Even if swap is disabled, disk activity becomes continuous, with the system unresponsive. For example, right now the system is working (albeit a tad slow), with only firefox and wing ide running, and I have 2Gb cached with only 45Mb mapped: $ free total used free shared buffers cached Mem: 3346388 3247328 99060 0 8416 2117980 -/+ buffers/cache: 1120932 2225456 Swap: 2144668 519448 1625220 $ cat /proc/meminfo MemTotal: 3346388 kB MemFree: 97128 kB Buffers: 7872 kB Cached: 2120224 kB SwapCached: 413860 kB Active: 2304596 kB Inactive: 865984 kB Active(anon): 2279168 kB Inactive(anon): 830236 kB Active(file): 25428 kB Inactive(file): 35748 kB Unevictable: 32 kB Mlocked: 32 kB HighTotal: 2492940 kB HighFree: 5456 kB LowTotal: 853448 kB LowFree: 91672 kB SwapTotal: 2144668 kB SwapFree: 1625244 kB Dirty: 84 kB Writeback: 0 kB AnonPages: 629304 kB Mapped: 45768 kB Slab: 45600 kB SReclaimable: 21756 kB SUnreclaim: 23844 kB PageTables: 4468 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 3817860 kB Committed_AS: 3735020 kB VmallocTotal: 122880 kB VmallocUsed: 9352 kB VmallocChunk: 66600 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 4096 kB DirectMap4k: 16376 kB DirectMap4M: 888832 kB If I try to drop the caches, little happes: # sync ; echo 3 > /proc/sys/vm/drop_caches ; free total used free shared buffers cached Mem: 3346388 3220580 125808 0 3020 2100600 -/+ buffers/cache: 1116960 2229428 Swap: 2144668 519356 1625312 Right now I've vm.swappiness = 5, but I've tried also with 0 and 1 (without noticeable differences).

  • Is there any way to tweak / rotate mouse orientation? Any applications? Registry edits?

    - by calbar
    I've got a very frustrating issue with my new Logitech Marathon Mouse M705. It is absolutely perfect for what I need, with the exception that it tracks on an angle for some reason. What I mean is when you slide the cursor to the left, it trends upward - when you slide to the right, it trends down. Moving the cursor along a flat horizontal line is no longer a natural motion - you need to fight what I suspect is a mechanical error of some kind. Unfortunately, I've already exchanged this mouse once and tested both on different Windows 7 and Mac OS machines - the problem continues to occur. So is there a software solution for me? I'm incredibly surprised there is no simple way to adjust the orientation... How can every mouse manufacturer possibly adjust their hardware to track to everyone's tastes? What about those who need to flip orientation a full 90 or 180 degrees? I only need to adjust mine a few degrees, but I'm sure that need has arisen as well. Anyway, I'm running the latest SetPoint drivers (6.00) on Windows 7 and there are no orientation options available. I've checked out uberOptions (http://uberoptions.net/) and the M705 isn't supported yet (with the last version update over 6 months ago). MAF Mouse (http://www.maf-soft.de/mafmouse/) instructions are a very strange series of mouse clicks to activate? This app also seems a little overkill and costs $$ (which I'm willing to pay as a last resort). Is there no universal registry value for mouse orientation? How about for SetPoint drivers specifically? I've done a simple search in regedit without any luck. An XML file somewhere? Anything?? Thanks a million for any help - it's driving me nuts!

  • How to make 7zip faster

    - by user34463
    I normally use winRAR over 7Zip simply because its faster and only a little less efficient with compression. I did a few tests on different filetypes and sizes comparing the 7zip and winRAR default settings on their normal compression and their best compression, and in a lot of cases winRAR was 50% faster and in some it was actually 100% faster. But, I do like FOSS more. So here are my questions: Is there a way to make 7zip speed up? I'd like it to at least be on par with rar's speed Is there a way to make recovery segments in 7zip like you can in rar? I didn't see any, but I guess it could be a command line thing. I tested winrar and 7zip using the latest stable version of each (4.something with 7zip). Is the 9.x beta release noticeably faster at compression? I'm talking about faster at a comparable setting in WinRAR, not just lowering to bare minimum compression. If it matters, I use a quad core intel i7 720 (1.6ghz)/(2.8ghz) with 4gb DDR3 ram, and the 64-bit version of 7zip.

  • I need a piece software to use with my HP F4280 scanner.

    - by D Connors
    So, I got this printer/scanner about a year ago, and I'm really happy with it. The only thing is that I never really liked the HP scanning software that came with it. A few months ago I reformatted and reinstalled windows 7. Then, once I plugged in the printer, I noticed that windows recognized it automatically, and offered to install all the drivers by itself. So instead of manually installing the driver that came in the CD, I simply let windows automatically install it from its servers, and so far it's great. Instead of HP's scanning software (that really wasn't pleasing me), I got a very simplified interface that is more than enough for my ocasional scanning habits. Until today. Today I had to scan a bunch of old pictures for my father. And that simple interface felt like it was lacking quite a few features to make this repetitive task a little easier. And that's why I'm now looking for a good software to use for scanning. By "good" I mean anything well thought out, and specially anything that will make my life easier when repetitive-scanning. It doesn't need to have professional tweaking options, but having them is not a problem either. You guys got anything?

  • Windows 7 Sysprep Default User

    - by Demonwolf
    I seem to be having a problem with implementing my sysprep. I have been playing with Windows 7, WAIK, Server 2008 R2 and various other things. I managed to create a WIM with everything I need installed and I have worked out the autounattend.xml. I now have a Windows 7 64-bit complete unattended install from a USB device. It has all my programs, setting and everything done except one thing - the default profile set up 100% correctly. I have created a mostly set up default profile. I booted into audit mode, customized the Administrator account (mostly anyway) and then used sysprep with an unattend.xml file containing the copyprofile=true command. The file was set up with the WSIM and does not contain any extra info. This all works wonderfully. I recreated the WIM and all was good. I then decided to move the default location of the visible stuff in the user profile (Documents, Music, Pictures etc.) without changing the location of Appdata or other hidden folders. This is where things went a little... wrong. I went to the user folder (generally has the User name) with all the other folders in it. I right clicked on My Documents, found the location tab and changed it to M:\Documents. Now if I run sysprep /generalize /oobe /reboot /unattend:unattend.xml it starts the generalise... then spits out a fatal error and goes no further. The setuperr.log contains the following errors: 2011-08-18 23:21:43, Error [0x0f0043] SYSPRP WinMain:The sysprep dialog box returned FALSE 2011-08-18 23:31:57, Error [0x0f0082] SYSPRP LaunchDll:Failure occurred while executing 'C:\Windows\System32\slc.dll,SLReArmWindows', returned error code -1073425657 2011-08-18 23:31:57, Error [0x0f0070] SYSPRP RunExternalDlls:An error occurred while running registry sysprep DLLs, halting sysprep execution. dwRet = -1073425657 2011-08-18 23:31:57, Error [0x0f00a8] SYSPRP WinMain:Hit failure while processing sysprep generalize internal providers; hr = 0xc004d307 Does anyone have any ideas how I can redirect My Documents and other items in a user file to a second drive in the default profile so it affects each person logging in?

  • List of Hidden / Virtual Windows User Accounts

    - by Synetech inc.
    I’m trying to find a way to get a comprehensive list of user accounts on a Windows 7 system, including hidden ones. The User Accounts dialog (>control userpasswords2) only shows the normal user accounts, and even the Local User and Groups editor only shows normal user accounts and standard hidden/disabled ones like Administrator and Guest. The Select Users or Groups dialog has a Find Now button which which combines users and groups, but alas, it has the same contents as the LUG. I’m looking for a more comprehensive list that includes “super-hidden” / virtual user accounts like TrustedInstaller (or to be more accurate, NT Service\TrustedInstaller—notice the different “domain”). I checked HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList, but the SpecialAccounts key does not exist. I also checked HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList, and while it does have the SystemProfile, LocalService, and NetworkService accounts listed, it does not have others (like TrustedInstaller and its ilk). TrustedInstaller specifically is a little confusing because it is a user, a service, and an executable file. I am using it as an example because it is “super hidden” in that it does not seem to be listed in any sort of user list. (As an experiment, I tried searching the whole registry for “trustedinstaller” to see if I could find a place where it is listed as a user, but found none.) To be clear, what I am looking for is a list of all accounts that can be used in a user input-field such as in permissions dialogs or as a runas argument.

  • Backup Gmail using Mail.app and IMAP without redundancy

    - by Cawas
    I don't care for actually using mail app, I use mostly the gmail interface and mail app just for offline, for quickly reading and eventually replying. Everything is working fine, I think I've followed every guide out there... Here's a great one. But I could find nothing about avoiding redundancy. Well, I can manually do that either by using POP or by checking off most of my labels out of IMAP. But I do use a lot of labels and I often label messages with more than 1 label. And I want them on mail app. Is there anyway to make it keep just 1 copy of repeated messages? Maybe there's a message id or checksum that could be used... If there isn't a way to do it, be assured I still prefer having the extra messages and "wasting" space rather than not having any. edit: I've came across many solutions for finding duplicate files, but they just delete the files. That just make things worst: Mail will just sync it all again. I've realized it's probably better to keep two accounts setup, POP for backup and IMAP for everything else with removing the "All Mail" from it. That's because if the "All Mail" on the server is deleted for any reason, my "All Mail" local will also get deleted, while POP will keep all files regardless of the server. This doesn't solve the redundancy issue at all, but it doesn't create any new issue as well, and I can even use the search properly, without duplicated results, if I search just on the POP. So it helps optimizing a little bit. But I still think the best way to solve this issue would be having something such as aamann's Mail Scripts tweaked to hardlinking the duplicates rather than deleting, and optimized to not need to scan everything every time. I'm trying to contact him and see what we can do. At any pace, I'm still looking for an answer!
