  • Emailing smtp with Python error

    - by jakecar
    I can't figure out why this isn't working. I'm trying to send an email from my school email address with this code I got online. The same code works for sending from my GMail address. Does anyone know what this error means? The error occurs after waiting for about one and a half minutes. import smtplib FROMADDR = "FROM_EMAIL" LOGIN = "USERNAME" PASSWORD = "PASSWORD" TOADDRS = ["TO_EMAIL"] SUBJECT = "Test" msg = ("From: %s\r\nTo: %s\r\nSubject: %s\r\n\r\n" % (FROMADDR, ", ".join(TOADDRS), SUBJECT) ) msg += "some text\r\n" server = smtplib.SMTP('OUTGOING_SMTP', 587) server.set_debuglevel(1) server.ehlo() server.starttls() server.login(LOGIN, PASSWORD) server.sendmail(FROMADDR, TOADDRS, msg) server.quit() And here's the error I get: Traceback (most recent call last): File "emailer.py", line 13, in server = smtplib.SMTP('OUTGOING_SMTP', 587) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/smtplib.py", line 239, in init (code, msg) = self.connect(host, port) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/smtplib.py", line 295, in connect self.sock = self._get_socket(host, port, self.timeout) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/smtplib.py", line 273, in _get_socket return socket.create_connection((port, host), timeout) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/socket.py", line 514, in create_connection raise error, msg socket.error: [Errno 60] Operation timed out

  • Is there a way to optimize this mysql query...?

    - by SpikETidE
    Hi Everyone... Say, I got these two tables.... Table 1 : Hotels hotel_id hotel_name 1 abc 2 xyz 3 efg Table 2 : Payments payment_id payment_date hotel_id total_amt comission p1 23-03-2010 1 100 10 p2 23-03-2010 2 50 5 p3 23-03-2010 2 200 25 p4 23-03-2010 1 40 2 Now, I need to get the following details from the two tables Given a particular date (say, 23-03-2010), the sum of the total_amt for each of the hotel for which a payment has been made on that particular date. All the rows that has the date 23-03-2010 ordered according to the hotel name A sample output is as follows... +------------+------------+------------+---------------+ | hotel_name | date | total_amt | commission | +------------+------------+------------+---------------+ | * abc | 23-03-2010 | 140 | 12 | +------------+------------+------------+---------------+ |+-----------+------------+------------+--------------+| || paymt_id | date | total_amt | commission || |+-----------+------------+------------+--------------+| || p1 | 23-03-2010 | 100 | 10 || |+-----------+------------+------------+--------------+| || p4 | 23-03-2010 | 40 | 2 || |+-----------+------------+------------+--------------+| +------------+------------+------------+---------------+ | * xyz | 23-03-2010 | 250 | 30 | +------------+------------+------------+---------------+ |+-----------+------------+------------+--------------+| || paymt_id | date | total_amt | commission || |+-----------+------------+------------+--------------+| || p2 | 23-03-2010 | 50 | 5 || |+-----------+------------+------------+--------------+| || p3 | 23-03-2010 | 200 | 25 || |+-----------+------------+------------+--------------+| +------------------------------------------------------+ Above the sample of the table that has to be printed... The idea is first to show the consolidated detail of each hotel, and when the '*' next to the hotel name is clicked the breakdown of the payment details will become visible... But that can be done by some jquery..!!! The table itself can be generated with php... Right now i am using two separate queries : One to get the sum of the amount and commission grouped by the hotel name. The next is to get the individual row for each entry having that date in the table. This is, of course, because grouping the records for calculating sum() returns only one row for each of the hotel with the sum of the amounts... Is there a way to combine these two queries into a single one and do the operation in a more optimized way...?? Hope i am being clear.. Thanks for your time and replies...

  • Another IKImageView Question

    - by Brian Postow
    I'm trying to use the select and copy feature of the IKImageView. If all you want to do is have an app with an image, select a portion and copy it to the clipboard, it's easy. You set the copy menu pick to the first responder's copy:(id) method and magically everything works. However, if you want something more complicated, like you want to copy as part of some other operation, I can't seem to find the method to do this. IKImageView doesn't seem to have a copy method, it doesn't seem to have a method that will even tell you the selected rectangle! I have gone through Hillegass' book, so I understand how the clipboard works, just not how to get the portion of the image out of the view... Now, I'm starting to think that I made a mistake in basing my project on IKImageView, but it's what Preview is built on (or so I've read), so I figured it had to be stable... and anyway, now it's too late, I'm too deep in this to start over... So, other than not using IKImageView, any suggestions on how to copy the select region to the clipboard manually?

  • Reformat SQLGeography polygons to JSON

    - by James
    I am building a web service that serves geographic boundary data in JSON format. The geographic data is stored in an SQL Server 2008 R2 database using the geography type in a table. I use [ColumnName].ToString() method to return the polygon data as text. Example output: POLYGON ((-6.1646509904325884 56.435153006374627, ... -6.1606079906751 56.4338050060666)) MULTIPOLYGON (((-6.1646509904325884 56.435153006374627 0 0, ... -6.1606079906751 56.4338050060666 0 0))) Geographic definitions can take the form of either an array of lat/long pairs defining a polygon or in the case of multiple definitions, an array or polygons (multipolygon). I have the following regex that converts the output to JSON objects contained in multi-dimensional arrays depending on the output. Regex latlngMatch = new Regex(@"(-?[0-9]{1}\.\d*)\s(\d{2}.\d*)(?:\s0\s0,?)?", RegexOptions.Compiled); private string ConvertPolysToJson(string polysIn) { return this.latlngMatch.Replace(polysIn.Remove(0, polysIn.IndexOf("(")) // remove POLYGON or MULTIPOLYGON .Replace("(", "[") // convert to JSON array syntax .Replace(")", "]"), // same as above "{lng:$1,lat:$2},"); // reformat lat/lng pairs to JSON objects } This is actually working pretty well and converts the DB output to JSON on the fly in response to an operation call. However I am no regex master and the calls to String.Replace() also seem inefficient to me. Does anyone have any suggestions/comments about performance of this?

  • Call WCF Service Through Javascript, AJAX, or JQuery

    - by obautista
    I created a number of standard WCF Services (Service Contract and Host (svc) are in separate assemblies). I fired up a Web Site in IIS to host the Services (i.e., address is http://services:1000/wcfservices.svc). Then in my Web Site project I added the reference. I am able to call the services normally. I am needed to call some of the services client side. Not sure if I should be looking at articles calling WCF services through AJAX, JQuery, or JSON enabled WCF Services. Can anyone provide any thoughts or experience with configuring as such? Some of the changes I made was adding the following to the Operation Contract: [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "SetFoo")] void SetFoo(string Id); Then this above the implementation of the interface: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] Then in the service webconfig I have this (parens are angle brackets): <serviceHostingEnvironment aspNetCompatibilityEnabled="true"> <baseAddressPrefixFilters> <add prefix="http://services:1000/wcfservices.svc/"/>> </baseAddressPrefixFilters> </serviceHostingEnvironment> <serviceHostingEnvironment multipleSiteBindingsEnabled="false" /> Then in the client side I attempted this: <asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server"> <compositeScript> <Scripts> <asp:ScriptReference Path="http://Flixsit:1000/FlixsitWebServices.svc" /> </Scripts> </CompositeScript> </asp:ScriptManagerProxy> I am attempting to call the service like this in javascript: wcfservices.SetFoo(string Id); Nothing is working. If it is idea or a better solution to call JSON enable, JQuery, etc....I am willing to make any changes. Thanks for any suggestions/tips provided....

  • RIA Services for transmitting non DB object-graph

    - by Mike Gates
    I have been getting into RIA services because I thought it would simplify dealing with the services layer of web applications I wish to build. I see lots of examples out there showing how to create DomainService classes which expose and consume entities that have some kind of relational database backing, and therefore have foreign-key relationships. However, I would like to know how to expose and consume normal object graphs...objects that contain references to eachother but don't have foreign keys. For example, say I want a service operation called "GetFolderInformation(string pathToFolder)". I want this to return a custom object called "FolderInformation" structured with: - string Name - IEnumerable<FileInformation> Files I cannot get this to work because it seems that RIA wants to deal with entities that have foreign key relationships. Why? Why can't the serializer just see my object references and recreate that in the proxy on the other side? Data exists behind service layers that doesn't necessarily have foreign key relationships...like folder/file for example. EDIT: I realized I hadn't asked my question! My question is, is there a way to do what I am trying to do?

  • How to keep a trace of a record inside a nested repeater?

    - by Amokrane
    Hi, I have the following implementation: As you can see I have a repeater (listing the Machines) and a nested repeater (listing the WindowsServices inside each Machine). For each Windows Service I can perform an action using a button. However, to perform this action I need to know which Machine and which WindowsService are concerned. This is my code: protected void Page_Init(object sender, EventArgs e) { rptMachine.ItemDataBound += new RepeaterItemEventHandler(rptMachine_ItemDataBound); } protected void Page_Load(object sender, EventArgs e) { // bind the Machine repeater rptMachine.DataSource = _monitoringService.Machines; rptMachine.DataBind(); } protected void rptMachine_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { Repeater nestedRepeater = (Repeater) e.Item.FindControl("rptWindowsService"); nestedRepeater.DataSource = ((IMachine) e.Item.DataItem).WindowsServices; nestedRepeater.DataBind(); Button btnActionInner = null; // bind the action button situated inside the nested repeater foreach(RepeaterItem ri in nestedRepeater.Items) { if((Button)ri.FindControl("btnAction") != null) { btnActionInner = (Button) ri.FindControl("btnAction"); btnActionInner.CommandName = "ActionState"; btnActionInner.CommandArgument = strWindowsService; } } } } protected void rptWindowsService_ItemCommand(object source, RepeaterCommandEventArgs e) { // do the specific action stop/run for the windows service if (e.CommandName == "ActionState") { if(((Button)(e.CommandSource)).Text.Equals("Stop")) { } else if(((Button)(e.CommandSource)).Text.Equals("Run")) { } } } } } So basically I need to know (inside rptWindowsService_ItemCommand) what is the pair that is concerned by the operation. What's the best way to do that? Don't hesitate to ask for more clarifications! Thanks

  • MySQL can't access root account or reset with mysqladmin

    - by glumptious
    So if I type mysql -u root I'm supposedly logged in, however upon trying to create or access a database I get this lovely error: ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'test1'. I haven't the foggiest idea why after logging in as root it's trying access DB's as ''@'localhost' and it's driving me a bit crazy right now. Possibly related, when I try to set the root password I get the error mysqladmin: Can't turn off logging; error: 'Access denied; you need (at least one of) the SUPER privilege(s) for this operation'. I've tried removing mysql-server via running apt-get purge mysql-server and then reinstalling with no luck. This is running Ubuntu Server 12.10 64-bit and mysql is indeed running. --Edit-- I wonder if perhaps there is no root user. So I try to start MySQL with --skip-grant-tables and the create the root user but then I'm given this: ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement. Fun fun fun fun fun.

  • Changing the system time zone succeeds once and then no longer changes

    - by Adam Driscoll
    I'm using the WinAPI to set the time zone on a Windows XP SP3 box. I'm reading the time zone information from the HKLM\Software\Microsoft\WindowsNT\Time Zones\<time zone name> key and then setting the time zone to the specified time zone. I enumerate the keys under the Time Zones key, grab the TZI value and stuff it into a TIME_ZONE_INFORMATION struct to be passed to SetTimeZoneInformation. All seems to work on the first pass. The time zone changes, no error is returned. The second time I perform this operation (same user, new session, on login before userinit) the call succeeds but the system does not reflect the time zone change. Neither the clock nor time stamps on files are updated to the new time zone. When I navigate to: HKLM\System\CurrentControlSet\Control\TimeZoneInformation my new time zone information is present. A couple strange things are happening when I'm setting my time zone: Also when I parse the TZI binary value from the registry to store in my TIME_ZONE_INFORMATION struct I'm noticing the struct has the DaylightDate.wDay and StandardDate.wDay field always set to 0 I tried to call GetTimeZoneInformation right after I call SetTimeZoneInformation but the call fails with a 1300 error (Not all privileges or groups referenced are assigned to the caller. ) I'm also making sure to send a WM_BROADCAST message so Explorer knows whats going on. Think it's the parsing of the byte array to the TIME_ZONE_INFORMATION struct? Or am I missing some thing else important? EDIT: Found a document stating why this is happening: here. Privilege was introduced in Vista...thanks MSDN docs... Per the Microsoft documentation I'm enabling the SE_TIME_ZONE_NAME privilege for the current processes token. But when I attempt to call LookupPriviledgeValue for SE_TIME_ZONE_NAME I get a 1313 error (A specified privilege does not exist. ).

  • How to share data between SSRS Security and Data Processing extension?

    - by user2904681
    I've spent a lot of time trying to solve the issue pointed in title and have no found a solution yet. I use MS SSRS 2012 with custom Security (based on Form Authentication and ClaimsPrincipal) and Data Processing extensions. In Data extension level I need to apply filter programmatically based on one of the claim which I have access in Security extension level only. Here is the problem: I do know how to pass the claim from Security to Data Processing extension code... What I've tried: IAuthenticationExtension.LogonUser(string userName, string password, string authority) { ... ClaimsPrincipal claimsPrincipal = CreateClaimsPrincipal(...); Thread.CurrentPrincipal = claimsPrincipal; HttpContext.Current.User = claimsPrincipal; ... }; But it doesn't work. It seems SSRS overrides it within either GenericPrincipal or FormsIdentity internally. The possible workaround I'm thinking about (but haven't checked it yet): 1. Create HttpModule which will create HttpContext with all required information (minus: will be invoke getting claims each time - huge operation) 2. Write to custom SQL table to store logged users information which is required for Data extension and then read it 3. try somehow to append to cookies due to LogOn and then read each time on IAuthenticationExtension.GetUserInfo and fill HttpContext None of them seems to be a good solution. I would be grateful for any help/advise/comments.

  • Pseudo code for instruction description

    - by Claus
    Hi, I am just trying to fiddle around what is the best and shortest way to describe two simple instructions with C-like pseudo code. The extract instruction is defined as follows: extract rd, rs, imm This instruction extracts the appropriate byte from the 32-bit source register rs and right justifies it in the destination register. The byte is specified by imm and thus can take the values 0 (for the least-significant byte) and 3 (for the most-significant byte). rd = 0x0; // zero-extend result, ie to make sure bits 31 to 8 are set to zero in the result rd = (rs && (0xff << imm)) >> imm; // this extracts the approriate byte and stores it in rd The insert instruction can be regarded as the inverse operation and it takes a right justified byte from the source register rs and deposits it in the appropriate byte of the destination register rd; again, this byte is determined by the value of imm tmp = 0x0 XOR (rs << imm)) // shift the byte to the appropriate byte determined by imm rd = (rd && (0x00 << imm)) // set appropriate byte to zero in rd rd = rd XOR tmp // XOR the byte into the destination register This looks all a bit horrible, so I wonder if there is a little bit a more elegant way to describe this bahaviour in C-like style ;) Many thanks, Claus

  • .NET threading solution for long queries

    - by Eddie
    Senerio We have an application that records incidents. An external database needs to be queried when an incident is approved by a supervisor. The queries to this external database are sometimes taking a while to run. This lag is experienced through the browser. Possible Solution I want to use threading to eliminate the simulated hang to the browser. I have used the Thread class before and heard about ThreadPool. But, I just found BackgroundWorker in this post. MSDN states: The BackgroundWorker class allows you to run an operation on a separate, dedicated thread. Time-consuming operations like downloads and database transactions can cause your user interface (UI) to seem as though it has stopped responding while they are running. When you want a responsive UI and you are faced with long delays associated with such operations, the BackgroundWorker class provides a convenient solution. Is BackgroundWorker the way to go when handling long running queries? What happens when 2 or more BackgroundWorker processes are ran simultaneously? Is it handled like a pool?

  • Google App Engine - Caching generated HTML

    - by Alexander
    I have written a Google App Engine application that programatically generates a bunch of HTML code that is really the same output for each user who logs into my system, and I know that this is going to be in-efficient when the code goes into production. So, I am trying to figure out the best way to cache the generated pages. The most probable option is to generate the pages and write them into the database, and then check the time of the database put operation for a given page against the time that the code was last updated. Then, if the code is newer than the last put to the database (for a particular HTML request), new HTML will be generated and served, and cached to the database. If the code is older than the last put to the database, then I will just get the HTML direct from the database and serve it (therefore avoiding all the CPU wastage of generating the HTML). I am not only looking to minimize load times, but to minimize CPU usage. However, one issue that I am having is that I can't figure out how to programatically check when the version of code uploaded to the app engine was updated. I am open to any suggestions on this approach, or other approaches for caching generated html. Note that while memcache could help in this situation, I believe that it is not the final solution since I really only need to re-generate html when the code is updated (as opposed to every time the memcache expires). Kind Regards, and thank you in advance for any suggestions you may be able to offer. -Alex

  • Time complexity with bit cost

    - by Keyser
    I think I might have completely misunderstood bit cost analysis. I'm trying to wrap my head around the concept of studying an algorithm's time complexity with respect to bit cost (instead of unit cost) and it seems to be impossible to find anything on the subject. Is this considered to be so trivial that no one ever needs to have it explained to them? Well I do. (Also, there doesn't even seem to be anything on wikipedia which is very unusual). Here's what I have so far: The bit cost of multiplication and division of two numbers with n bits is O(n^2) (in general?) So, for example: int number = 2; for(int i = 0; i < n; i++ ){ number = i*i; } has a time complexity with respect to bit cost of O(n^3), because it does n multiplications (right?) But in a regular scenario we want the time complexity with respect to the input. So, how does that scenario work? The number of bits in i could be considered a constant. Which would make the time complexity the same as with unit cost except with a bigger constant (and both would be linear). Also, I'm guessing addition and subtraction can be done in constant time, O(1). Couldn't find any info on it but it seems reasonable since it's one assembler operation.

  • How close can I get C# to the performance of C++ for small intensive tasks?

    - by SLC
    I was thinking about the speed difference of C++ to C# being mostly about C# compiling to byte-code that is taken in by the JIT compiler (is that correct?) and all the checks C# does. I notice that it is possible to turn a lot of these functions off, both in the compile options, and possibly through using the unsafe keyword as unsafe code is not verifiable by the common language runtime. Therefore if you were to write a simple console application in both languages, that flipped an imaginary coin an infinite number of times and displayed the results to the screen every 10,000 or so iterations, how much speed difference would there be? I chose this because it's a very simple program. I'd like to test this but I don't know C++ or have the tools to compile it. This is my C# version though: static void Main(string[] args) { unsafe { Random rnd = new Random(); int heads = 0, tails = 0; while (true) { if (rnd.NextDouble() > 0.5) heads++; else tails++; if ((heads + tails) % 1000000 == 0) Console.WriteLine("Heads: {0} Tails: {1}", heads, tails); } } } Is the difference enough to warrant deliberately compiling sections of code "unsafe" or into DLLs that do not have some of the compile options like overflow checking enabled? Or does it go the other way, where it would be beneficial to compile sections in C++? I'm sure interop speed comes into play too then. To avoid subjectivity, I reiterate the specific parts of this question as: Does C# have a performance boost from using unsafe code? Do the compile options such as disabling overflow checking boost performance, and do they affect unsafe code? Would the program above be faster in C++ or negligably different? Is it worth compiling long intensive number-crunching tasks in a language such as C++ or using /unsafe for a bonus? Less subjectively, could I complete an intensive operation faster by doing this?

  • VS2010 express beta2 - no add reference dialog, no open file/project dialogs

    - by David
    Just installed VS2010 express for Windows Phone last night. Install went smoothly. It creates a project, compiles, and deploys the app to the emulator. Here's the problem: When I try to "Add Reference" through the Project menu, I do not get the Add Reference dialog box. Same thing if I right click References in the solution explorer and click Add Reference. That's not all. "File...Open" and "File...Open Project" also fail to throw up an open file dialog box. When attempting any of these actions, the IDE quickly loses and regains focus. Even pressing a keyboard shortcut (Ctrl+O) causes the IDE to quickly lose and regain focus, but no open file dialog box appears. This is what I have tried, not particularly in this order: 1. Turned off UAC 2. Monitored file and registry access using Process Monitor during a File...Open operation. File activity showed mostly "SUCCESS" with a few "FAST IO DISALLOWED" and a few "INVALID DEVICE REQUEST" results. Registry activity showed mostly "SUCCESS" with some "NAME NOT FOUND" and a few "BUFFER OVERFLOW" results. 3. Created a new, clean Windows account to run the IDE from 4. Forced a test project to add a reference to "System.Xml.Linq" by editing the ".csproj" project file. Project failed to load in the IDE. I don't have these problems at all on 2 other Windows 7 computers with VS2010 C# express beta 2 installed. One machine is 32bit and the other 64bit, both Home Premium edition. My system: Windows 7 Home Premium, 64bit Other Visual Studio products installed: VS2008 C# express, VS2008 C++ express One other thing to note: Several months ago I installed the non-phone distribution of VS2010 C# express beta 2, and I had the same exact problems. Back then I chalked it up to being beta and went back to VS2008 C# express, where I do not have these issues.

Fielname... web.config... Error: There is a duplicate..." Browsing to the URL displays: "Http 500.19" internal server error.. There is a duplicate... 'system.web.extensions/scripting/scriptResourceHandler' section defined...." Running the app from VS 2008 an "Unable to start debugging on the web server..." dialog is displayed. Things Tried Looked at other application directories on same IIS server. No problem view web.config contents or serving up the app. Removed and re-added the application in IIS. Checked out a new version of the source code. Reverted to prior versions of the web.config file. Looked for web.config files that might have duplicate sections in: Inetpub root. "C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config" The "Views" subfolder of the ASP.Net MVC app. Checked out source code to another dev machine. Setup IIS 7 app folder. No problem with Web.config. Question If the reason for this error is another web.config file where else should I look? Are there other reasons for these symptoms?

  • How do I load an XML document, add and remove nodes, then apply it to a ASP DataGrid control?

    - by JFOX
    I have a pretty simple operation but am struggling with how to implement it. I am loading XML from an external data source using a DataSet.ReadXml(), the creating a new XMLDataDocument from that data set, then syncing the Dataset back to the XMLDataDocument like so: doc = new XmlDataDocument(dsDataSet); dsDataSet.EnforceConstraints = false; dsDataSet= doc.DataSet; Once loaded I do two things to the XmlDataDocument: Loop through and check if a purely meta node, count, exists right beneath the root node and if so remove it. a thumb node exists in a second level nodelist and if not, create and append it. This is all going a expected because the result of doc.save() looks correct. Where I'm having an issue is updating the Dataset, which is being applied as the data source for an ASP DataGrid. Once all the above XMLDoc manipaulation is done I do this: dsDataSet.Merge(doc.DataSet); dsDataSet.AcceptChanges(); I then apply the data set to the grid control: dgList.DataSource = dsDataSet; dgList.DataBind(); But, when I do this I get this error on the site: System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'thumb'. What did I miss?

  • memory alignment within gcc structs

    - by Mumbles
    I am porting an application to an ARM platform in C, the application also runs on an x86 processor, and must be backward compatible. I am now having some issues with variable alignment. I have read the gcc manual for __attribute__((aligned(4),packed)) I interpret what is being said as the start of the struct is aligned to the 4 byte boundry and the inside remains untouched because of the packed statement. originally I had this but occasionally it gets placed unaligned with the 4 byte boundary. typedef struct { unsigned int code; unsigned int length; unsigned int seq; unsigned int request; unsigned char nonce[16]; unsigned short crc; } __attribute__((packed)) CHALLENGE; so I change it to this. typedef struct { unsigned int code; unsigned int length; unsigned int seq; unsigned int request; unsigned char nonce[16]; unsigned short crc; } __attribute__((aligned(4),packed)) CHALLENGE; The understand I stated earlier seems to be incorrect as both the struct is now aligned to a 4 byte boundary, and and the inside data is now aligned to a four byte boundary, but because of the endianess, the size of the struct has increased in size from 42 to 44 bytes. This size is critical as we have other applications that depend on the struct being 42 bytes. Could some describe to me how to perform the operation that I require. Any help is much appreciated.

  • Can a large transaction log cause cpu hikes to occur

    - by Simon Rigby
    Hello all, I have a client with a very large database on Sql Server 2005. The total space allocated to the db is 15Gb with roughly 5Gb to the db and 10 Gb to the transaction log. Just recently a web application that is connecting to that db is timing out. I have traced the actions on the web page and examined the queries that execute whilst these web operation are performed. There is nothing untoward in the execution plan. The query itself used multiple joins but completes very quickly. However, the db server's CPU hikes to 100% for a few seconds. The issue occurs when several simultaneous users are working on the system (when I say multiple .. read about 5). Under this timeouts start to occur. I suppose my question is, can a large transaction log cause issues with CPU performance? There is about 12Gb of free space on the disk currently. The configuration is a little out of my hands but the db and log are both on the same physical disk. I appreciate that the log file is massive and needs attending to, but I'm just looking for a heads up as to whether this may cause CPU spikes (ie trying to find the correlation). The timeouts are a recent thing and this app has been responsive for a few years (ie its a recent manifestation). Many Thanks,

  • Examples of monoids/semigroups in programming

    - by jkff
    It is well-known that monoids are stunningly ubiquitous in programing. They are so ubiquitous and so useful that I, as a 'hobby project', am working on a system that is completely based on their properties (distributed data aggregation). To make the system useful I need useful monoids :) I already know of these: Numeric or matrix sum Numeric or matrix product Minimum or maximum under a total order with a top or bottom element (more generally, join or meet in a bounded lattice, or even more generally, product or coproduct in a category) Set union Map union where conflicting values are joined using a monoid Intersection of subsets of a finite set (or just set intersection if we speak about semigroups) Intersection of maps with a bounded key domain (same here) Merge of sorted sequences, perhaps with joining key-equal values in a different monoid/semigroup Bounded merge of sorted lists (same as above, but we take the top N of the result) Cartesian product of two monoids or semigroups List concatenation Endomorphism composition. Now, let us define a quasi-property of an operation as a property that holds up to an equivalence relation. For example, list concatenation is quasi-commutative if we consider lists of equal length or with identical contents up to permutation to be equivalent. Here are some quasi-monoids and quasi-commutative monoids and semigroups: Any (a+b = a or b, if we consider all elements of the carrier set to be equivalent) Any satisfying predicate (a+b = the one of a and b that is non-null and satisfies some predicate P, if none does then null; if we consider all elements satisfying P equivalent) Bounded mixture of random samples (xs+ys = a random sample of size N from the concatenation of xs and ys; if we consider any two samples with the same distribution as the whole dataset to be equivalent) Bounded mixture of weighted random samples Which others do exist?

  • Writing catch block with cleanup operations in Java ...

    - by kedarmhaswade
    I was not able to find any advise on catch blocks in Java that involve some cleanup operations which themselves could throw exceptions. The classic example is that of stream.close() which we usually call in the finally clause and if that throws an exception, we either ignore it by calling it in a try-catch block or declare it to be rethrown. But in general, how do I handle cases like: public void doIt() throws ApiException { //ApiException is my "higher level" exception try { doLower(); } catch(Exception le) { doCleanup(); //this throws exception too which I can't communicate to caller throw new ApiException(le); } } I could do: catch(Exception le) { try { doCleanup(); } catch(Exception e) { //ignore? //log? } throw new ApiException(le); //I must throw le } But that means I will have to do some log analysis to understand why cleanup failed. If I did: catch(Exception le) { try { doCleanup(); } catch(Exception e) { throw new ApiException(e); } It results in losing the le that got me here in the catch block in the fist place. What are some of the idioms people use here? Declare the lower level exceptions in throws clause? Ignore the exceptions during cleanup operation?

  • ABGroupAddMember - Cannot Add Contact to Group (iPhone Address Book)

    - by cookeecut
    Hi, I wonder if someone can help me out on this: I'm writing some code to copy a set of contacts received through a web application into the Address Book. I want to put all these new contacts under a certain group. My code successfully creates the group and adds the contacts into the address book. However, the 'ABGroupAddMember' operation fails. It fails without an error and the result it returns is true, meaning that according to the debugger the contact should have been added to the group. However, this does not work. The portion of my loop code that adds the contact to the address book and then assigns it to the group is this: ABAddressBookAddRecord(addressBook,person, &anError); ABAddressBookSave(addressBook,&anError); ABGroupAddMember(fusionLiveGroupRef,person, &anError); ABAddressBookSave(addressBook,&anError); All references are valid. No errors are returned. All operations return true. What is going wrong?
