  • Microsoft Dog Food Days

    - by Chris Haaker
    There is a free two-day event called "Dog Food Conference 2012" being held at the Microsoft offices in Columbus, Ohio (home to my beloved Ohio State Buckeyes) that looks to be promising. It covers a wide-array of technologies with a Microsoft focus and some other things pertinent to the IT community. From the site: "This is a local conference by community IT professionals showcasing Microsoft technologies. There will be speakers from MS Gold Certified Partners, MS MVPs, IT authors, community leads, and MS Corp subject matter experts."

  • How to get XML into a Dictionary with an Expression?

    - by DaveDev
    I have the following XML: <PerformancePanel page="PerformancePanel.ascx" title=""> <FundGroup heading="Net Life Managed Funds"> <fund id="17" countryid="N0" index="24103723" /> <fund id="81" countryid="N0" index="24103723" /> <fund id="127" countryid="N0" index="24103722" /> <fund id="345" countryid="N0" index="24103723" /> <fund id="346" countryid="N0" index="24103723" /> </FundGroup> <FundGroup heading="Net Life Specialist Funds"> <fund id="110" countryid="N0" index="24103717" /> <fund id="150" countryid="N0" index="24103719" /> <fund id="119" countryid="N0" index="24103720" /> <fund id="115" countryid="N0" index="24103727" /> <fund id="141" countryid="N0" index="24103711" /> <fund id="137" countryid="N0" /> <fund id="146" countryid="N0" /> <fund id="133" countryid="N0" /> <fund id="90" countryid="N0" /> <fund id="104" countryid="N0" /> <fund id="96" countryid="N0" /> </FundGroup> </PerformancePanel> I can get the data into an anonymous object as follows: var offlineFactsheet = new { PerformancePanels = (from panel in doc.Elements("PerformancePanel") select new PerformancePanel { PerformanceFunds = (from fg in panel.Elements("FundGroup") select new { Heading = (fg.Attribute("heading") == null) ? "" : (string)fg.Attribute("heading"), Funds = (from fund in fg.Elements("fund") select new Fund { FundId = (int)fund.Attribute("id"), CountryId = (string)fund.Attribute("countryid"), FundIndex = (fund.Attribute("index") == null) ? null : new Index { Id = (int)fund.Attribute("index") }, FundNameAppend = (fund.Attribute("append") == null) ? "" : (string)fund.Attribute("append") }).ToList() }).ToDictionary(xx => xx.Heading, xx => xx.Funds)}; I'm trying to change my code such that I can assign the dictionary directly to a property of the class I'm working in, as described in this question. I'd like to have a Dictionary() where each header text is the key to the list of funds under it. I'm having difficulty applying the example in the linked question because that only returns a string, and this needs to return the dictionary. This is the point that I got to before it occurred to me that I'm lost!!!: this.PerformancePanels = doc.Elements("PerformancePanel").Select(e => { var control = (PerformancePanel)LoadControl(this.OfflineFactsheetPath + (string)e.Attribute("page")); control.PerformanceFunds = e.Elements("FundGroup").Select(f => { List<Fund> funds = (from fund in e.Elements("fund") select new Fund { FundId = (int)fund.Attribute("id"), CountryId = (string)fund.Attribute("countryid"), FundIndex = (fund.Attribute("index") == null) ? null : new Index { Id = (int)fund.Attribute("index") }, FundNameAppend = (fund.Attribute("append") == null) ? "" : (string)fund.Attribute("append") }).ToList(); string heading = (e.Attribute("heading") == null) ? "" : (string)e.Attribute("heading"); }).ToDictionary(xx => heading, xx => Funds); return control; }).ToList(); Could someone point me in the right direction please? I'm not even sure if 'Expression' is the right terminology. Could someone fill me in on that too? Thanks.

  • Is the use of explicit ' == true' comparison always bad? [closed]

    - by Slomojo
    Possible Duplicate: Make a big deal out of == true? I've been looking at a lot of code samples recently, and I keep noticing the use of... if( expression == true ) // do something... and... x = ( expression == true ) ? x : y; I've tended to always use... x = ( expression ) ? x : y; and... if( expression ) // do something... Where == true is implicit (and obvious?) Is this just a habit of mine, and I'm being picky about the explicit use of == true, or is it simply bad practice?

  • Google app engine issue 777 particular solution?

    - by Niklas R
    I use 64.202.189.170 (godaddy) for a HTTP access to a www...on google app engine like GAE issue 777 so that a blank subdomain forwards to www.domain I get the blank to respond by output "This website is temporarily unavailable, please try again later. " There's info about this issue here http://knol.google.com/k/google-apps-discussion-group#view and here http://code.google.com/p/googleappengine/issues/detail?id=777 Since I managed to do it with a .com domain (The godaddy DNS hosted gralumo.com correctly responds to www..) I now want to do it with an off-site DNS managed domain getting the following info about servers: $ ping montao.com.br PING montao.com.br (64.202.189.170) 56(84) bytes of data. 64 bytes from pwfwd-v01.prod.mesa1.secureserver.net (64.202.189.170): icmp_seq=1 ttl=113 time=188 ms 64 bytes from pwfwd-v01.prod.mesa1.secureserver.net (64.202.189.170): icmp_seq=2 ttl=113 time=188 ms ^C --- montao.com.br ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1001ms rtt min/avg/max/mdev = 188.459/188.692/188.926/0.493 ms ubuntu@ubuntu:~$ ping www.montao.com.br PING ghs.l.google.com (74.125.43.121) 56(84) bytes of data. 64 bytes from bw-in-f121.1e100.net (74.125.43.121): icmp_seq=1 ttl=56 time=30.2 ms 64 bytes from bw-in-f121.1e100.net (74.125.43.121): icmp_seq=2 ttl=56 time=28.0 ms 64 bytes from bw-in-f121.1e100.net (74.125.43.121): icmp_seq=3 ttl=56 time=24.2 ms ^C --- ghs.l.google.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 24.201/27.522/30.282/2.514 ms So it looks to me these are the same IP numbers whether or not it's off-site DNS. It's just that it works for one domain and not the other. Could it be just resetting the appspot app ie removing and adding it? Can you recommend how to proceed? Thanks in advance

  • StackOverFlowException - but oviously NO recursion/endless loop

    - by user567706
    Hi there, I'm now blocked by this problem the entire day, read thousands of google results, but nothing seems to reflect my problem or even come near to it... i hope any of you has a push into the right direction for me. I wrote a client-server-application (so more like 2 applications) - the client collects data about his system, as well as a screenshot, serializes all this into a XML stream (the picture as a byte[]-array]) and sends this to the server in regular intervals. The server receives the stream (via tcp), deserializes the xml to an information-object and shows the information on a windows form. This process is running stable for about 20-25 minutes at a submission interval of 3 seconds. When observing the memory usage there's nothing significant to see, also kinda stable. But after these 20-25 mins the server throws a StackOverflowException at the point where it deserializes the tcp-stream, especially when setting the Image property from the byte[]-array. I thoroughly searched for recursive or endless loops, and regarding the fact that it occurs after thousands of sucessfull intervals, i could hardly imagine that. public byte[] ImageBase { get { MemoryStream ms = new MemoryStream(); _screen.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); return ms.GetBuffer(); } set { if (_screen != null) _screen.Dispose(); //preventing well-known image memory leak MemoryStream ms = new MemoryStream(value); try { _screen = Image.FromStream(ms); //<< EXCEPTION THROWING HERE } catch (StackOverflowException ex) //thx to new CLR management this wont work anymore -.- { Console.WriteLine(ex.Message + Environment.NewLine + ex.StackTrace); } ms.Dispose(); ms = null; } } I hope that more code would be unnecessary, or it could get very complex... Please help, i have no clue at all anymore thx Chris

  • Calling function using 'new' is less expensive than without it?

    - by Matthew Taylor
    Given this very familiar model of prototypal construction: function Rectangle(w,h) { this.width = w; this.height = h; } Rectangle.prototype.area = function() { return this.width * this.height; }; Can anyone explain why calling "new Rectangle(2,3)" is consistently 10x FASTER than calling "Rectangle(2,3)" without the 'new' keyword? I would have assumed that because new adds more complexity to the execution of a function by getting prototypes involved, it would be slower. Example: var myTime; function startTrack() { myTime = new Date(); } function stopTrack(str) { var diff = new Date().getTime() - myTime.getTime(); println(str + ' time in ms: ' + diff); } function trackFunction(desc, func, times) { var i; if (!times) times = 1; startTrack(); for (i=0; i<times; i++) { func(); } stopTrack('(' + times + ' times) ' + desc); } var TIMES = 1000000; trackFunction('new rect classic', function() { new Rectangle(2,3); }, TIMES); trackFunction('rect classic (without new)', function() { Rectangle(2,3); }, TIMES); Yields (in Chrome): (1000000 times) new rect classic time in ms: 33 (1000000 times) rect classic (without new) time in ms: 368 (1000000 times) new rect classic time in ms: 35 (1000000 times) rect classic (without new) time in ms: 374 (1000000 times) new rect classic time in ms: 31 (1000000 times) rect classic (without new) time in ms: 368

  • How to make += operator keep the object reference?

    - by orloffm
    Say, I have a class: class M { public int val; And also a + operator inside it: public static M operator +(M a, M b) { M c = new M(); c.val = a.val + b.val; return c; } } And I've got a List of the objects of the class: List<M> ms = new List(); M obj = new M(); obj.val = 5; ms.Add(obj); Some other object: M addie = new M(); addie.val = 3; I can do this: ms[0] += addie; and it surely works as I expect - the value in the list is changed. But if I want to do M fromList = ms[0]; fromList += addie; it doesn't change the value in ms for obvious reasons. But intuitively I expect ms[0] to also change after that. Really, I pick the object from the list and then I increase it's value with some other object. So, since I held a reference to ms[0] in fromList before addition, I want still to hold it in fromList after performing it. Are there any ways to achieve that?

I'll appreciate if somebody can help me. Thanks

  • Teamcity build agent gives 504 gateway timeout

    I have a new teamcity build agent machine, which when started up tries to connect to the build server and fails.

Other VMS with similar configuration can connect fine and do not report this error. What can possibly be preventing this connection?

  • How much network latency is "typical" for east - west coast USA?

    - by Jeff Atwood
    At the moment we're trying to decide whether to move our datacenter from the west coast to the east coast. However, I am seeing some disturbing latency numbers from my west coast location to the east coast. Here's a sample result, retrieving a small .png logo file in Google Chrome and using the dev tools to see how long the request takes: West coast to east coast: 215 ms latency, 46 ms transfer time, 261 ms total West coast to west coast: 114 ms latency, 41 ms transfer time, 155 ms total It makes sense that Corvallis, OR is geographically closer to my location in Berkeley, CA so I expect the connection to be a bit faster.. but I'm seeing an increase in latency of +100ms when I perform the same test to the NYC server. That seems .. excessive to me. Particularly since the time spent transferring the actual data only increased 10%, yet the latency increased 100%! That feels... wrong... to me. I found a few links here that were helpful (through Google no less!) ... Does routing distance affect performance significantly? How does geography affect network latency? Latency in Internet connections from Europe to USA ... but nothing authoritative. So, is this normal? It doesn't feel normal. What is the "typical" latency I should expect when moving network packets from the east coast <--> west coast of the USA?

  • Difference in performance: local machine VS amazon medium instance

    - by user644745
    I see a drastic difference in performance matrix when i run it with apache benchmark (ab) in my local machine VS production hosted in amazon medium instance. Same concurrent requests (5) and same total number of requests (111) has been run against both. Amazon has better memory than my local machine. But there are 2 CPUs in my local machine vs 1 CPU in m1.medium. My internet speed is very low at the moment, I am getting Transfer rate as 25.29KBps. How can I improve the performance ? Do not know how to interpret Connect, Processing, Waiting and total in ab output.

  • AWS elastic load balancer basic issues

    - by Jones
    I have an array of EC2 t1.micro instances behind a load balancer and each node can manage ~100 concurrent users before it starts to get wonky. i would THINK if i have 2 such instances it would allow my network to manage 200 concurrent users... apparently not. When i really slam the server (blitz.io) with a full 275 concurrents, it behaves the same as if there is just one node. it goes from 400ms response time to 1.6 seconds (which for a single t1.micro is expected, but not 6). So the question is, am i simply not doing something right or is ELB effectively worthless? Anyone have some wisdom on this?

  • 403 error after adding javascript to masterpage for sharepoint.

    - by Jeremy
    I am attempting to add highslide-with-html.js from http://highslide.com/ to my masterpage. I am receiving a 403 forbidden error when I use the provided masterpage. I have placed it in C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\1033. Test javascript files such as pirate.js which consists solely of alert("Arr!"); have loaded from the same directory. I have provided the code for the masterpage. When I do not reference the problem javascript file there is no 403 error. <%@ Master language="C#" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <%@ Import Namespace="Microsoft.SharePoint" %> <%@ Register Tagprefix="SPSWC" Namespace="Microsoft.SharePoint.Portal.WebControls" Assembly="Microsoft.SharePoint.Portal, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Register Tagprefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages" Assembly="Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Register Tagprefix="PublishingWebControls" Namespace="Microsoft.SharePoint.Publishing.WebControls" Assembly="Microsoft.SharePoint.Publishing, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Register Tagprefix="PublishingNavigation" Namespace="Microsoft.SharePoint.Publishing.Navigation" Assembly="Microsoft.SharePoint.Publishing, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Register TagPrefix="wssuc" TagName="Welcome" src="~/_controltemplates/Welcome.ascx" %> <%@ Register TagPrefix="wssuc" TagName="DesignModeConsole" src="~/_controltemplates/DesignModeConsole.ascx" %> <%@ Register TagPrefix="PublishingVariations" TagName="VariationsLabelMenu" src="~/_controltemplates/VariationsLabelMenu.ascx" %> <%@ Register Tagprefix="PublishingConsole" TagName="Console" src="~/_controltemplates/PublishingConsole.ascx" %> <%@ Register TagPrefix="PublishingSiteAction" TagName="SiteActionMenu" src="~/_controltemplates/PublishingActionMenu.ascx" %> <html dir="<%$Resources:wss, multipages_direction_dir_value %>" runat="server" __expr-val-dir="ltr"> <head runat="server"> <meta name="GENERATOR" content="Microsoft SharePoint"> <meta http-equiv="Content-Type" content="text/html;

  • NHibernate (3.1.0.4000) NullReferenceException using Query<> and NHibernate Facility

    - by TigerShark
    I have a problem with NHibernate, I can't seem to find any solution for. In my project I have a simple entity (Batch), but whenever I try and run the following test, I get an exception. I've triede a couple of different ways to perform a similar query, but almost identical exception for all (it differs in which LINQ method being executed). The first test: [Test] public void QueryLatestBatch() { using (var session = SessionManager.OpenSession()) { var batch = session.Query<Batch>() .FirstOrDefault(); Assert.That(batch, Is.Not.Null); } } The exception: System.NullReferenceException : Object reference not set to an instance of an object. at NHibernate.Linq.NhQueryProvider.PrepareQuery(Expression expression, ref IQuery query, ref NhLinqExpression nhQuery) at NHibernate.Linq.NhQueryProvider.Execute(Expression expression) at System.Linq.Queryable.FirstOrDefault(IQueryable`1 source) The second test: [Test] public void QueryLatestBatch2() { using (var session = SessionManager.OpenSession()) { var batch = session.Query<Batch>() .OrderBy(x => x.Executed) .Take(1) .SingleOrDefault(); Assert.That(batch, Is.Not.Null); } } The exception: System.NullReferenceException : Object reference not set to an instance of an object. at NHibernate.Linq.NhQueryProvider.PrepareQuery(Expression expression, ref IQuery query, ref NhLinqExpression nhQuery) at NHibernate.Linq.NhQueryProvider.Execute(Expression expression) at System.Linq.Queryable.SingleOrDefault(IQueryable`1 source) However, this one is passing (using QueryOver<): [Test] public void QueryOverLatestBatch() { using (var session = SessionManager.OpenSession()) { var batch = session.QueryOver<Batch>() .OrderBy(x => x.Executed).Asc .Take(1) .SingleOrDefault(); Assert.That(batch, Is.Not.Null); Assert.That(batch.Executed, Is.LessThan(DateTime.Now)); } } Using the QueryOver< API is not bad at all, but I'm just kind of baffled that the Query< API isn't working, which is kind of sad, since the First() operation is very concise, and our developers really enjoy LINQ. I really hope there is a solution to this, as it seems strange if these methods are failing such a simple test. EDIT I'm using Oracle 11g, my mappings are done with FluentNHibernate registered through Castle Windsor with the NHibernate Facility. As I wrote, the odd thing is that the query works perfectly with the QueryOver< API, but not through LINQ.

  • OSB and Coherence Integration

    - by mark.ms.smith
    Anyone who has tried to manage Coherence nodes or tried to cache results in OSB, will appreciate the new functionality now available. As of WebLogic Server 10.3.4, you can use the WebLogic Administration Server, via the Administration Console or WLST, and java-based Node Manager to manage and monitor the life cycle of stand-alone Coherence cache servers. This is a great step forward as the previous options mainly involved writing your own scripts to do this. You can find an excellent description of how this works at James Bayer’s blog. You can also find the WebLogic documentation here.As of Oracle Service Bus 11gR1 (11.1.1.3.0), OSB now supports service result caching for Business Bervices with Coherence. If you use Business Services that return somewhat static results that do not change often, you can configure those Business Services to cache results. For Business Services that use result caching, you can control the time to live for the cached result. After the cached result expires, the next Business Service call results in invoking the back-end service to get the result. This result is then stored in the cache for future requests to access. I’m thinking that this caching functionality would be perfect for some sort of cross reference data that was refreshed nightly by batch. You can find the OSB Business Service documentation here.Result Caching in a dedicated JVMThis example demonstrates these new features by configuring a OSB Business Service to cache results in a separate Coherence JVM managed by WebLogic. The reason why you may want to use a separate, dedicated JVM is that the result cache data could potentially be quite large and you may want to protect your OSB java heap.In this example, the client will call an OSB Proxy Service to get Employee data based on an Employee Id. Using a Business Service, OSB calls an external system. The results are automatically cached and when called again, the respective results are retrieved from the cache rather than the external system.Step 1 – Set up your Coherence Server Via the OSB Administration Server Console, create your Coherence Server to be used as the results cache.Here are the configured Coherence Server arguments from the Server Start tab. Note that I’m using the default Cache Config and Override files in the domain.-Xms256m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=256m -Dtangosol.coherence.override=/app/middleware/jdev_11.1.1.4/user_projects/domains/osb_domain2/config/osb/coherence/osb-coherence-override.xml -Dtangosol.coherence.cluster=OSB-cluster -Dtangosol.coherence.cacheconfig=/app/middleware/jdev_11.1.1.4/user_projects/domains/osb_domain2/config/osb/coherence/osb-coherence-cache-config.xml -Dtangosol.coherence.distributed.localstorage=true -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dcom.sun.management.jmxremote Just incase you need it, here is my Coherence Server classpath:/app/middleware/jdev_11.1.1.4/oracle_common/modules/oracle.coherence_3.6/coherence.jar: /app/middleware/jdev_11.1.1.4/modules/features/weblogic.server.modules.coherence.server_10.3.4.0.jar: /app/middleware/jdev_11.1.1.4/oracle_osb/lib/osb-coherence-client.jarBy default, OSB will try and create a local result cache instance. You need to disable this by adding the following JVM parameters to each of the OSB Managed Servers:-Dtangosol.coherence.distributed.localstorage=false -DOSB.coherence.cluster=OSB-clusterIf you need more information on configuring a remote result cache, have a look at the configuration documentration under the heading Using an Out-of-Process Coherence Cache Server.Step 2 – Configure your Business Service Under the respective Business Service Message Handling Configuration (Advanced Properties), you need to enable “Result Caching”. Additionally, you need to determine what the cache data will be keyed on. In the example below, I’m keying it on the unique Employee Id.The Results As this test was on my laptop, the actual timings are just an indication that there is a benefit to caching results. Using my test harness, I sent 10,000 requests to OSB, all with the same Employee Id. In this case, I had result caching disabled.You can see that this caused the back end Business Service (BS_GetEmployeeData) to be called for each request. Then after enabling result caching, I sent the same number of identical requests.You can now see the Business Service was only invoked once on the first request. All subsequent requests used the Results Cache.

  • OpenVPN not sending traffic to internet?

    - by coleifer
    I've set up openvpn on my pi and am running into a small issue. I can connect to the VPN server and ping it just fine, and I can also connect to other machines on my local network. However I am unable, when connected to the VPN, to reach the outside world (either by name lookup or IP). here are the details: On the server the tun0 interface: tun0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500 inet 10.8.0.1 netmask 255.255.255.255 destination 10.8.0.2 unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 100 (UNSPEC) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 I can ping it just fine: # ping -c 3 10.8.0.1 PING 10.8.0.1 (10.8.0.1) 56(84) bytes of data. 64 bytes from 10.8.0.1: icmp_seq=1 ttl=64 time=0.159 ms 64 bytes from 10.8.0.1: icmp_seq=2 ttl=64 time=0.155 ms 64 bytes from 10.8.0.1: icmp_seq=3 ttl=64 time=0.156 ms --- 10.8.0.1 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2002ms Routing table # ip route show default via 192.168.1.1 dev eth0 metric 204 10.8.0.0/24 via 10.8.0.2 dev tun0 10.8.0.2 dev tun0 proto kernel scope link src 10.8.0.1 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.6 metric 204 I also have ip traffic forwarding: net.ipv4.ip_forward = 1 I do not have any custom iptables rules (that I'm aware of).

Here's some of the server logs at the bottom of this gist: https://gist.github.com/coleifer/6ef95c3008f130249933/edit I am frankly out of ideas! I don't think it's my client because both my laptop and my phone (which has an openvpn client) exhibit the same behavior. I had OpenVPN installed on this pi before using debian and it worked, so I don't think it's my router but of course anything is possible.

  • PC to USB transfer slow

    - by Vipin Ms
    I'm having trouble with USB transfer,not with external hard disk. Transfer starts with like, for the transfer of 700MB file it starts with 30mb/s and towards the end it stops at 0s and stays put for like 3-4 mins to transfer the last bit. I have tried different USB devices, but no luck. Is it a bug? Another important point is, in Kubuntu there is no such issue. So is it something related to Gnome? I'm using Ubuntu 11.10 64bit. Somebody please help, it's really annoying. Here are the details. PC all of my drives are in ext4. USB I tried ext3,ntfs and fat32. All having the same problem.

  • Powershell Exchange script returning inconsistent results - PS weirdness

    - by Ian
    Maybe someone can shed some light on a bit of Powershell weirdness I've come across and can't explain. This PS script returns a list of exchange databases, their sizes and the number of mailboxes in each one: Get-MailboxDatabase | Select Server, StorageGroupName, Name, @{Name="Size (GB)";Expression={$objitem = (Get-MailboxDatabase $_.Identity); $path = "`\`\" + $objitem.server + "`\" + $objItem.EdbFilePath.DriveName.Remove(1).ToString() + "$"+ $objItem.EdbFilePath.PathName.Remove(0,2); $size = ((Get-ChildItem $path).length)/1048576KB; [math]::round($size, 2)}}, @{Name="Size (MB)";Expression={$objitem = (Get-MailboxDatabase $_.Identity); $path = "`\`\" + $objitem.server + "`\" + $objItem.EdbFilePath.DriveName.Remove(1).ToString() + "$"+ $objItem.EdbFilePath.PathName.Remove(0,2); $size = ((Get-ChildItem $path).length)/1024KB; [math]::round($size, 2)}}, @{Name="No. Of Mbx";expression={(Get-Mailbox -Database $_.Identity | Measure-Object).Count}} | Format-table –AutoSize If I add a simple 'sort name' before the 'format-table' my resulting table contains blanks where the database sizes and number of mailboxes should appear (not zeros, blank empty space).... but only in some rows, not all rows. Some rows contain numbers! If I put the '|sort name| ' after the initial 'get-mailboxdatabase' it works fine. Whats even weirder is if I do the following: Execute the above command Add the sort before format-table Execute the new command Execute the initial command again What I see is different amounts in each of the three cases - all of which are incorrect. Yet 1 and 3 are the same command and the only difference with 2 is a sort. 1 and 3 should, at a minimum, return the same results. I get blanks where I should have MBs If I add the sort after the get-mailboxdatabase, it always returns identical results (as it should). Can anyone suggest an explanation as to what may be going on? If its of any help in reading the expression, I've reformatted it here to make it a bit more readable: Get-MailboxDatabase | Select Server, StorageGroupName, Name, @{Name="Size (GB)";Expression={ $objitem = (Get-MailboxDatabase $_.Identity); $path = "`\`\" + $objitem.server + "`\" + $objItem.EdbFilePath.DriveName.Remove(1).ToString() + "$" + $objItem.EdbFilePath.PathName.Remove(0,2); $size = ((Get-ChildItem $path).length)/1048576KB; [math]::round($size, 2) }}, @{Name="Size (MB)";Expression={ $objitem = (Get-MailboxDatabase $_.Identity); $path = "`\`\" + $objitem.server + "`\" + $objItem.EdbFilePath.DriveName.Remove(1).ToString() + "$" + $objItem.EdbFilePath.PathName.Remove(0,2); $size = ((Get-ChildItem $path).length)/1024KB; [math]::round($size, 2) }}, @{Name="No. Of Mbx";expression={ (Get-Mailbox -Database $_.Identity | Measure-Object).Count }} | Format-table –AutoSize

  • Why does pinging a local router return "Destination Host Unreachable"?

    - by Matt H
    I have two tomato routers. One is bridged wirelessly with the other. I have a new server on the network. It's running Ubuntu Server 11.04. They are all connected like this: A - Linux PC B - New Server C - Mac Mini D - Macbook T1 - Tomato 1 T2 - Tomato 2 They are connected like so: A -----+-T1 ==== wireless bridge ==== T2----- ADSL modem | | C & D Connected wirelessly to T2 B -----+ A, C & D do not experience any issues. I have an active SSH session to B from A and it's not experiencing any loss. B, the new server occasionally cannot ping T2 and therefore cannot connect to the internet. However, A can always contact B and B can ping A and B When the network is lost, B can still ping T1, but not T2 yet at the same as B has lost connection to T2, A can still ping T2. Any ideas on what this could be? there is nothing that gives any clues in any of the logs on either router or the linux server. One thing that is interesting is that I set up a ping running between B and T2. T2 has the IP address 192.68.1.1 Here is what I am seeing: From 192.168.1.1 icmp_seq=26 Destination Host Unreachable From 192.168.1.1 icmp_seq=27 Destination Host Unreachable From 192.168.1.1 icmp_seq=28 Destination Host Unreachable From 192.168.1.1 icmp_seq=29 Destination Host Unreachable From 192.168.1.1 icmp_seq=30 Destination Host Unreachable From 192.168.1.1 icmp_seq=31 Destination Host Unreachable From 192.168.1.1 icmp_seq=33 Destination Host Unreachable From 192.168.1.1 icmp_seq=34 Destination Host Unreachable From 192.168.1.1 icmp_seq=35 Destination Host Unreachable 64 bytes from 192.168.1.1: icmp_req=36 ttl=63 time=3.40 ms 64 bytes from 192.168.1.1: icmp_req=37 ttl=63 time=5.70 ms 64 bytes from 192.168.1.1: icmp_req=38 ttl=63 time=2.25 ms 64 bytes from 192.168.1.1: icmp_req=39 ttl=63 time=2.18 ms 64 bytes from 192.168.1.1: icmp_req=40 ttl=63 time=3.12 ms 64 bytes from 192.168.1.1: icmp_req=41 ttl=63 time=2.15 ms 64 bytes from 192.168.1.1: icmp_req=42 ttl=63 time=1.97 ms 64 bytes from 192.168.1.1: icmp_req=43 ttl=63 time= And it cycles to being reachable and not. So I guess you could say the question is, why is the router responding that it cannot be reached?

  • what should I read in Windows [closed]

    - by Umesha MS
    I think I am asking generic question. Being a developer in windows what should I read to improve my skills? Do I need to read concepts on need basis or do I need to read concepts well in advance? If I want to read the concepts in advance then what topics do I need to read. (Note : I am a Windows developer. I use c++ programming language, Win32/MFC frame work and I use Visual studio IDE.) Updated: To be more specific when a fresher comes to my team I will ask him to read the following things and I tell him that these are very important. 1)C++ : 1 The C++ Programming Language by Bjarne Stroustrup's 2 Thinking in C++ 2nd Edition by Bruce Eckel 2)Win32/MFC : 1 Programming Applications for Microsoft Windows by Jeffrey Richter 2 windows programming by charles petzold 3 Programming Windows with MFC –by Jeff Prosise For 2 years and above developer I ask them to read 1)Above concepts (C++ and Win32/MFC)are mandate 2)Design Pattern : 1)Gang Of Four. 2)Head first patter. 3)Design princples. But for above 6 years’ experience developer what are the concepts are important.
