  • How would you tackle a pattern-finding program?

    - by Neil
    Just to be clear, I don't think this should be question better suited for stackoverflow.com simply because there's not a single answer but a wide range of possible solutions, making this question far more subjective in nature. I was curious how you guys would tackle a pattern-finding program, which is to say I'd do the following operations: I enter in some input. Program predicts my next input based on all previous inputs. Rinse. Repeat. Since the amount of input I could provide is so varied, including empty strings, conventional means such as switches or regular expressions are out, since it would require you to have an inkling of information about what to expect. I was thinking about some form of genetic algorithm, yet even then I don't have a clue as to how to approach a problem of this caliber. I think some feedback mechanism would be necessary as well as to let the program know how close it was. Anyone had to do a similar type program before?

  • Recognizing text fields according to their label value

    - by Pierpaolo Bagnasco
    I have an application who has text fields (not select, not checkbox or other types) where an user can enter some value, like this: ISBN and E-Mail are the label of each input. Now I have to automatically test these inputs according to their label. The question is: how to recognize that, for example, the first input requires an ISBN code? I programmed something like this: turn the label value to lowercase check if the label value contains isbn if so set the field value to a random ISBN code (i.e.: 1234567890), else set it to a random value (default) For the email field: turn the label value to lowercase check if the label value contains e-mail or email or mail if so set the field value to a random email (i.e.: [email protected]), else set it to a random value (default) And so on for each text field I encounter. Is that reliable? How can I improve the "recognizing part"? I know only the label value and the field value (what is already written in the field by default) for each text input.

  • Test if char is '0'-'9' [migrated]

    - by Chris Okyen
    My Java code is // if the first character is not 0-9 if( (((input.substring(0,0)).compareTo("1")) < 0 || (((input.substring(0,0)).compareTo("9")) < 0)); { System.out.println("Error: The first digit of the temperature is not 1-9. Force Exiting Program. "); System.exit(1); // exit the program } But it slips through even with input like '1123' or '912' or '222', and gives this error message. Whether I have it 0 for first and < 0 for the second, or 0 and 0, or < 0 and < 0, or even < o and 0... How come?

  • Bacula windows client could not connect to Bacula director

    - by pr0f-r00t
    I have a Bacula server on my Linux Debian squeeze host (Bacula version 5.0.2) and a Bacula client on Windows XP SP3. On my network each client can see each other, can share files and can ping.

  • Tips for XNA WP7 Developers

    - by Michael B. McLaughlin
    There are several things any XNA developer should know/consider when coming to the Windows Phone 7 platform. This post assumes you are familiar with the XNA Framework and with the changes between XNA 3.1 and XNA 4.0. It’s not exhaustive; it’s simply a list of things I’ve gathered over time. I may come back and add to it over time, and I’m happy to add anything anyone else has experienced or learned as well. Display · The screen is either 800x480 or 480x800. · But you aren’t required to use only those resolutions. · The hardware scaler on the phone will scale up from 240x240. · One dimension will be capped at 800 and the other at 480; which depends on your code, but you cannot have, e.g., an 800x600 back buffer – that will be created as 800x480. · The hardware scaler will not normally change aspect ratio, though, so no unintended stretching. · Any dimension (width, height, or both) below 240 will be adjusted to 240 (without any aspect ratio adjustment such that, e.g. 200x240 will be treated as 240x240). · Dimensions below 240 will be honored in terms of calculating whether to use portrait or landscape. · If dimensions are exactly equal or if height is greater than width then game will be in portrait. · If width is greater than height, the game will be in landscape. · Landscape games will automatically flip if the user turns the phone 180°; no code required. · Default landscape is top = left. In other words a user holding a phone who starts a landscape game will see the first image presented so that the “top” of the screen is along the right edge of his/her phone, such that the natural behavior would be to turn the phone 90° so that the top of the phone will be held in the user’s left hand and the bottom would be held in the user’s right hand. · The status bar (where the clock, battery power, etc., are found) is hidden when the Game-derived class sets GraphicsDeviceManager.IsFullScreen = true. It is shown when IsFullScreen = false. The default value is false (i.e. the status bar is shown). · You should have a good reason for hiding the status bar. Users find it helpful to know what time it is, how much charge their battery has left, and whether or not their phone is in service range. This is especially true for casual games that you expect someone to play for a few minutes at a time, e.g. while waiting for some event to start, for a phone call to come in, or for a train, bus, or subway to arrive. · In portrait mode, the status bar occupies 32 pixels of space. This means that a game with a back buffer of 480x800 will be scaled down to occupy approximately 461x768 screen pixels. Setting the back buffer to 480x768 (or some resolution with the same 0.625 aspect ratio) will avoid this scaling. · In landscape mode, the status bar occupies 72 pixels of space. This means that a game with a back buffer of 800x480 will be scaled down to occupy approximately 728x437 screen pixels. Setting the back buffer to 728x480 (or some resolution with the same 1.51666667 aspect ratio) will avoid this scaling. Input · Touch input is scaled with screen size. · So if your back buffer is 600x360, a tap in the bottom right corner will come in as (599,359). You don’t need to do anything special to get this automatic scaling of touch behavior. · If you do not use full area of the screen, any touch input outside the area you use will still register as a touch input. For example, if you set a portrait resolution of 240x240, it would be scaled up to occupy a 480x480 area, centered in the screen. If you touch anywhere above this area, you will get a touch input of (X,0) where X is a number from 0 to 239 (in accordance with your 240 pixel wide back buffer). Any touch below this area will give a touch input of (X,239). · If you keep the status bar visible, touches within its area will not be passed to your game. · In general, a screen measurement is the diagonal. So a 3.5” screen is 3.5” long from the bottom right corner to the top left corner. With an aspect ratio of 0.6 (480/800 = 0.6), this means that a phone with a 3.5” screen is only approximately 1.8” wide by 3” tall. So there are approximately 267 pixels in an inch on a 3.5” screen. · Again, this time in metric! 3.5 inches is approximately 8.89 cm. So an 8.89 cm screen is 8.89 cm long from the bottom right corner to the top left corner. With an aspect ratio of 0.6, this means that a phone with an 8.89 cm screen is only approximately 4.57 cm wide by 7.62 cm tall. So there are approximately 105 pixels in a centimeter on an 8.89 cm screen. · Think about the size of your finger tip. If you do not have large hands, think about the size of the fingertip of someone with large hands. Consider that when you are sizing your touch input. Especially consider that when you are spacing two touch targets near one another. You need to judge it for yourself, but items that are next to each other and are each 100x100 should be fine when it comes to selecting items individually. Smaller targets than that are ok provided that you leave space between them. · You want your users to have a pleasant experience. Making touch controls too small or too close to one another will make them nervous about whether they will touch the right target. Take this into account when you plan out your game initially. If possible, do some quick size mockups on an actual phone using colored rectangles that you position and size where you plan to have your game controls. Adjust as necessary. · People do not have transparent hands! Nor are their hands the size of a mouse pointer icon. Consider leaving a dedicated space for input rather than forcing the user to cover up to one-third of the screen with a finger just to play the game. · Another benefit of designing your controls to use a dedicated area is that you’re less likely to have players moving their finger(s) so frantically that they accidentally hit the back button, start button, or search button (many phones have one or more of these on the screen itself – it’s easy to hit one by accident and really annoying if you hit, e.g., the search button and then quickly tap back only to find out that the game didn’t save your progress such that you just wasted all the time you spent playing). · People do not like doing somersaults in order to move something forward with accelerometer-based controls. Test your accelerometer-based controls extensively and get a lot of feedback. Very well-known games from noted publishers have created really bad accelerometer controls and been virtually unplayable as a result. Also be wary of exceptions and other possible failures that the documentation warns about. · When done properly, the accelerometer can add a nice touch to your game (see, e.g. ilomilo where the accelerometer was used to move the background; it added a nice touch without frustrating the user; I also think CarniVale does direct accelerometer controls very well). However, if done poorly, it will make your game an abomination unto the Marketplace. Days, weeks, perhaps even months of development time that you will never get back. I won’t name names; you can search the marketplace for games with terrible reviews and you’ll find them. Graphics · The maximum frame rate is 30 frames per second. This was set as a compromise between battery life and quality. · At least one model of phone is known to have a screen refresh rate that is between 59 and 60 hertz. Because of this, using a fixed time step with a target frame rate of 30 will cause a slight internal delay to build up as the framework is forced to wait slightly for the next refresh. Eventually the delay will get to the point where a draw is skipped in order to recover from the delay. (See Nick's comment below for clarification.) · To deal with that delay, you can either stay with a fixed time step and set the frame rate slightly lower or else you can go to a variable time step and make sure to adjust all of your update data (e.g. player movement distance) to take into account the elapsed time from the last update. A variable time step makes your update logic slightly more complicated but will avoid frame skips entirely. · Currently there are no custom shaders. This might change in the future (there is no hardware limitation preventing it; it simply wasn’t a feature that could be implemented in the time available before launch). · There are five built-in shaders. You can create a lot of nice effects with the built-in shaders. · There is more power on the CPU than there is on the GPU so things you might typically off-load to the GPU will instead make sense to do on the CPU side. · This is a phone. It is not a PC. It is not an Xbox 360. The emulator runs on a PC and uses the full power of your PC. It is very good for testing your code for bugs and doing early prototyping and layout. You should not use it to measure performance. Use actual phone hardware instead. · There are many phone models, each of which has slightly different performance levels for I/O, screen blitting, CPU performance, etc. Do not take your game right to the performance limit on your phone since for some other phones you might be crossing their limits and leaving players with a bad experience. Leave a cushion to account for hardware differences. · Smaller screened phones will have slightly more dots per inch (dpi). Larger screened phones will have slightly less. Either way, the dpi will be much higher than the typical 96 found on most computer screens. Make sure that whoever is doing art for your game takes this into account. · Screens are only required to have 16 bit color (65,536 colors). This is common among smart phones. Using gradients on a 16 bit display can produce an ugly artifact known as banding. Banding is when, rather than a smooth transition from one color to another, you instead see distinct lines. Be careful to avoid this when possible. Banding can be avoided through careful art creation. Its effects can be minimized and even unnoticeable when the texture in question is always moving. You should be careful not to rely on “looks good on my phone” since some phones do have 32-bit displays and thus you’ll find yourself wondering why you’re getting bad reviews that complain about the graphics. Avoid gradients; if you can’t, make sure they are 16-bit safe. Audio · Never rely on sounds as your sole signal to the player that something is happening in the game. They might have the sound off. They might be playing somewhere loud. Etc. · You have to provide controls to disable sound & music. These should be separate. · On at least one model of phone, the volume control API currently has no effect. Players can adjust sound with their hardware volume buttons, but in game selectors simply won’t work. As such, it may not be worth the effort of providing anything beyond on/off switches for sound and music. · MediaPlayer.GameHasControl will return true when a game is hooked up to a PC running Zune. When Zune is running, any attempts to do anything (beyond check GameHasControl) with MediaPlayer will cause an exception to be thrown. If this exception is thrown, catch it and disable music. Exceptions take time to propagate; you don’t want one popping up in every single run of your game’s Update method. · Remember that players can already be listening to music or using the FM radio. In this case GameHasControl will be false and you should handle this appropriately. You can, alternately, ask the player for permission to stop their current music and play your music instead, but the (current) requirement that you restore their music when done is very hard (if not impossible) to deal with. · You can still play sound effects even when the game doesn’t have control of the music, but don’t think this is a backdoor to playing music. Your game will fail certification if your “sound effect” seems to be more like music in scope and length.

  • "Product installation unsuccessful, please reinstall" error in CorelDraw X3 on Windows 7

    - by Donotalo
    I've been using corel draw x3 and windows 7 for more than a month. I cannot remember when I last used corel draw x3. Today I've found something unusual. My PC has two account: one with admin rights and another is standard account. Corel Draw X3 runs fine on admin account, but when it is started from standard account (without admin right), it shows the following error: Product installation unsuccessful, please reinstall I could run this product definitely on standard user account last month. But it is not running now. I tried to run it with all compatibility mode: from windows 95 to vista service pack 2. For some mode, it opens and closes immediately after showing the splash screen, and for other mode it shows the above error. How to fix this problem?

  • virtual directory make file copy operation extremely slow on UNC Path (IIS 7.5 bug?)

    - by user144737
    When i create a website/virtual directory pointing to UNC path, its make our file copy extremely slow on the UNC path. 6 seconds for file copy (~13 M) on the UNC path without any virtual directory/website pointing to it. over 1 mins. for file copy (same files ~13M) on the same UNC path with virtual directory/website pointing to it. All file copy operation run on web server side. Our setting as below: Web server - Windows Server standard R2 2008 / IIS 7.5 File server - Windows Server standard 2003 I have tested this case on 3 servers (Windows Server standard R2 2008 / IIS 7.5) and got same result. I also tested this case on 2 windows 2003 / IIS 6, it won't slow down the file copy. Is it IIS 7.5 bug? any patch/hotfix to solve this case? Thank you. Gordon

  • Apache Errordocument (custom 503 page) works intermittently

    - by jimmycavnz
    We have Apache 2.2 running on Windows 2k3 and 2k8 R2 as a reverse proxy to downstream applications. Some of these applications may go offline during off-peak hours so we've implemented a custom 503 page like so: ErrorDocument 503 /error/serverTimeout.html ErrorDocument 504 /error/serverTimeout.html (the error directory is in Apaches's htdocs folder) If I make these changes, restart apache and then access the down application on firefox I see the custom page as expected. I then access it using my IE browser, it also works. If I close my IE browser and access it again, I get Apache's standard "Service Temporarily Unavailable" message instead of my custom page. Once I receive the standard error message, I never get the custom page again until I restart Apache. I've put the server on debug and I can't see any difference between the requests which return the custom error page and the requests which return the standard error message. Is there some weird proxy setting which is messing with the errordocument configuration? Any ideas?

  • Way to update / refresh / reschedule project plan after adding a vacation / changing calendar

    - by CodeCanvas
    I had created a project plan using MS-Project 2010 (not server). I had set the task schedule mode to "Auto Scheduled" and entered the necessary tasks. Since it is a single person project I also added one person to the Resource of the file and assigned that resource to all the tasks and leveled the project. After the plan was put in and tasks were leveled I figured the calendar was not correctly set (in UAE the weekend is Friday and Saturday instead of Saturday and Sunday). So, I updated the default calendar (Standard) of the project by going to Project-Change Working Time-Work Weeks and changed them as needed. But after doing this, the tasks are still scheduled over Friday and Saturday even though I have marked them as nonworking days in the standard calendar. I tried the following for the tasks to refresh, but I was not successful: Updated all tasks to use the "Standard" calendar in the project Selected option so that tasks do not ignore resource calendars Added a constraint "As Soon As Possible" Executed "Level All" Any help on solving this issue would be much appreciated, thanks in advance.

  • Google Apps for Business on a separate infrastructure?

    - by dustin
    Does anyone know if Google Apps for Business edition hosts the apps (gmail, calendar, etc.) on a physically separate infrastructure than the Standard (free) infrastructure? We've been growing increasingly annoyed with the lost/severely delayed email messages, downtime, etc. of Google Apps (standard) over time, and we are wondering if moving to the paid version would bring any benefits. Specifically, if the Business edition is not in some way on a different physical infrastructure, and we are in essence paying for a few small perks but still run on the usual standard/free setup, then we would probably have the same (or just as many) issues with the Business version. I've emailed Google's sales team responsible for GApps, but haven't heard anything back in 4 days, which already doesn't speak well for the service. So, anyone have any insight into this? Thanks in advance for any and all help :)

  • Daylight Savings Time and Microsoft Exchange woes

    - by Scott
    Ever since the switch from Standard Time to Daylight Time, the time on our e-mail messages has been ahead by one hour. This symptom has me wondering if the cause is improper configuration of daylight savings settings. Since we're in a client/server environment, the clients synchronize with the server, and the server synchronizes with Boulder, Colorado. If I set both the server and the clients to automatically switch to daylight savings, the clients seem to regard the server as being set to Standard Time and set themselves an hour ahead of it, which is really two hours ahead. Should the server switch to daylight savings and the clients follow along on their next synchronization, or should the server stay on Standard Time and the clients switch over? The system clock on the Exchange Server is currently displaying the correct time. How do I get the e-mail messages to display the correct time in Outlook?

  • Is it possible to upgrade using the Windows Server 2012 evaluation?

    - by Cerebrate
    I've got a Windows Server 2008 Standard installation here that I'm trying to upgrade to Windows Server 2012 Server, using the evaluation version. (The scenario is essentially that I need to test the upgrade, and specifically the upgrade process, before we spend the money on going ahead with the actual upgrade.) When I try to upgrade, it fails with the message: "Windows Server 2008 Standard cannot be upgraded to Windows Server 2012 Standard Evaluation (Server with a GUI). You can choose to install a new... (etc., etc.)" Is this (non-upgradability) a known limitation of the evaluation version? (Unfortunately, I haven't found a clear answer on this point.) And if not, any thoughts on where else I might look for the problem and solutions to it?

  • Windows 8.1 wants to format a USB stick with an unusual but valid GPT partitioning scheme, why?

    - by DonGar
    I have a USB stick formatted with GPT partitions. Some of the partitions are ext2, some are ext4, some are custom and funky. However, there is also a standard EFI partition, and a standard vfat partition. In Windows 7, both the EFI partition and the standard VFAT partition are visible and mount normally. But Windows 8.1 prompts to reformat the drive when it's inserted. I'm not surprised if Win 8 hides the EFI partition, but I didn't expect it to prompt for reformatting. I want to leave existing partitions alone, but have a VFAT partition that Windows 7, 8, and 8.1 will mount and display normally. Exactly how does Win 8 decide if a device needs to be formatted?

  • Is it normal that Software installs in Admin user folder?

    - by RoToRa
    I've got a new computer with Windows 7, which I'm using for the first time. For security I decided to create a standard user for everyday work instead of using an admin account. However when I install programs logged in as the standard user (such as Aptana right now) they always try to install in the admin's user folder (C:\Users\Admin\AppData...). I'd expect the programs to install to the standard user's folder or Progran Files as in XP. This also leads to that I need to grant admin rights whenever I start such a program. Of course I could just change the installation path every time, but I find this behavior strange. Ist it normal, or did I somehow mess up the Windows 7 installation?

  • Parallelism in .NET – Part 7, Some Differences between PLINQ and LINQ to Objects

    - by Reed
    In my previous post on Declarative Data Parallelism, I mentioned that PLINQ extends LINQ to Objects to support parallel operations.  Although nearly all of the same operations are supported, there are some differences between PLINQ and LINQ to Objects.  By introducing Parallelism to our declarative model, we add some extra complexity.  This, in turn, adds some extra requirements that must be addressed. In order to illustrate the main differences, and why they exist, let’s begin by discussing some differences in how the two technologies operate, and look at the underlying types involved in LINQ to Objects and PLINQ . LINQ to Objects is mainly built upon a single class: Enumerable.  The Enumerable class is a static class that defines a large set of extension methods, nearly all of which work upon an IEnumerable<T>.  Many of these methods return a new IEnumerable<T>, allowing the methods to be chained together into a fluent style interface.  This is what allows us to write statements that chain together, and lead to the nice declarative programming model of LINQ: double min = collection .Where(item => item.SomeProperty > 6 && item.SomeProperty < 24) .Min(item => item.PerformComputation()); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Other LINQ variants work in a similar fashion.  For example, most data-oriented LINQ providers are built upon an implementation of IQueryable<T>, which allows the database provider to turn a LINQ statement into an underlying SQL query, to be performed directly on the remote database. PLINQ is similar, but instead of being built upon the Enumerable class, most of PLINQ is built upon a new static class: ParallelEnumerable.  When using PLINQ, you typically begin with any collection which implements IEnumerable<T>, and convert it to a new type using an extension method defined on ParallelEnumerable: AsParallel().  This method takes any IEnumerable<T>, and converts it into a ParallelQuery<T>, the core class for PLINQ.  There is a similar ParallelQuery class for working with non-generic IEnumerable implementations. This brings us to our first subtle, but important difference between PLINQ and LINQ – PLINQ always works upon specific types, which must be explicitly created. Typically, the type you’ll use with PLINQ is ParallelQuery<T>, but it can sometimes be a ParallelQuery or an OrderedParallelQuery<T>.  Instead of dealing with an interface, implemented by an unknown class, we’re dealing with a specific class type.  This works seamlessly from a usage standpoint – ParallelQuery<T> implements IEnumerable<T>, so you can always “switch back” to an IEnumerable<T>.  The difference only arises at the beginning of our parallelization.  When we’re using LINQ, and we want to process a normal collection via PLINQ, we need to explicitly convert the collection into a ParallelQuery<T> by calling AsParallel().  There is an important consideration here – AsParallel() does not need to be called on your specific collection, but rather any IEnumerable<T>.  This allows you to place it anywhere in the chain of methods involved in a LINQ statement, not just at the beginning.  This can be useful if you have an operation which will not parallelize well or is not thread safe.  For example, the following is perfectly valid, and similar to our previous examples: double min = collection .AsParallel() .Select(item => item.SomeOperation()) .Where(item => item.SomeProperty > 6 && item.SomeProperty < 24) .Min(item => item.PerformComputation()); However, if SomeOperation() is not thread safe, we could just as easily do: double min = collection .Select(item => item.SomeOperation()) .AsParallel() .Where(item => item.SomeProperty > 6 && item.SomeProperty < 24) .Min(item => item.PerformComputation()); In this case, we’re using standard LINQ to Objects for the Select(…) method, then converting the results of that map routine to a ParallelQuery<T>, and processing our filter (the Where method) and our aggregation (the Min method) in parallel. PLINQ also provides us with a way to convert a ParallelQuery<T> back into a standard IEnumerable<T>, forcing sequential processing via standard LINQ to Objects.  If SomeOperation() was thread-safe, but PerformComputation() was not thread-safe, we would need to handle this by using the AsEnumerable() method: double min = collection .AsParallel() .Select(item => item.SomeOperation()) .Where(item => item.SomeProperty > 6 && item.SomeProperty < 24) .AsEnumerable() .Min(item => item.PerformComputation()); Here, we’re converting our collection into a ParallelQuery<T>, doing our map operation (the Select(…) method) and our filtering in parallel, then converting the collection back into a standard IEnumerable<T>, which causes our aggregation via Min() to be performed sequentially. This could also be written as two statements, as well, which would allow us to use the language integrated syntax for the first portion: var tempCollection = from item in collection.AsParallel() let e = item.SomeOperation() where (e.SomeProperty > 6 && e.SomeProperty < 24) select e; double min = tempCollection.AsEnumerable().Min(item => item.PerformComputation()); This allows us to use the standard LINQ style language integrated query syntax, but control whether it’s performed in parallel or serial by adding AsParallel() and AsEnumerable() appropriately. The second important difference between PLINQ and LINQ deals with order preservation.  PLINQ, by default, does not preserve the order of of source collection. This is by design.  In order to process a collection in parallel, the system needs to naturally deal with multiple elements at the same time.  Maintaining the original ordering of the sequence adds overhead, which is, in many cases, unnecessary.  Therefore, by default, the system is allowed to completely change the order of your sequence during processing.  If you are doing a standard query operation, this is usually not an issue.  However, there are times when keeping a specific ordering in place is important.  If this is required, you can explicitly request the ordering be preserved throughout all operations done on a ParallelQuery<T> by using the AsOrdered() extension method.  This will cause our sequence ordering to be preserved. For example, suppose we wanted to take a collection, perform an expensive operation which converts it to a new type, and display the first 100 elements.  In LINQ to Objects, our code might look something like: // Using IEnumerable<SourceClass> collection IEnumerable<ResultClass> results = collection .Select(e => e.CreateResult()) .Take(100); If we just converted this to a parallel query naively, like so: IEnumerable<ResultClass> results = collection .AsParallel() .Select(e => e.CreateResult()) .Take(100); We could very easily get a very different, and non-reproducable, set of results, since the ordering of elements in the input collection is not preserved.  To get the same results as our original query, we need to use: IEnumerable<ResultClass> results = collection .AsParallel() .AsOrdered() .Select(e => e.CreateResult()) .Take(100); This requests that PLINQ process our sequence in a way that verifies that our resulting collection is ordered as if it were processed serially.  This will cause our query to run slower, since there is overhead involved in maintaining the ordering.  However, in this case, it is required, since the ordering is required for correctness. PLINQ is incredibly useful.  It allows us to easily take nearly any LINQ to Objects query and run it in parallel, using the same methods and syntax we’ve used previously.  There are some important differences in operation that must be considered, however – it is not a free pass to parallelize everything.  When using PLINQ in order to parallelize your routines declaratively, the same guideline I mentioned before still applies: Parallelization is something that should be handled with care and forethought, added by design, and not just introduced casually.

  • RegexClean Transformation

    Use the power of regular expressions to cleanse your data right there inside the Data Flow. This transformation includes a full user interface for simple configuration, as well as advanced features such as error output configuration. Two regular expressions are used, a match expression and a replace expression. The transformation is designed around the named capture groups or match groups, and even supports multiple expressions. This allows for rich and complex expressions to be built, all through an easy to reuse transformation where a bespoke Script Component was previously the only alternative. Some simple properties are available for each column selected – Behaviour The two behaviour modes offer similar functionality but with a difference. Replace, replaces tokens with the input, and Emit overwrites the whole string. Cascade Cascade allows you to define multiple expressions, each on a new line. The match expression will be processed into one operation per line, which are then processed in order at run-time. Multiple replace expressions can also be specified, again each on a new line. If there is no corresponding replace expression for a match expression line, then the last replace expression will be used instead. It is common to have multiple match expressions, but only a single replace expression. Match Expression The expression used to define the named capture groups. This is where you can analyse the data, and tag or name elements within it as found by the match expression. Replace Expression The replace determines the final output. It will reference the named groups from the match expression and assembles them into the final output. If you want to use regular expressions to validate data then try the Regular Expression Transformation. Quick Start Guide Select a column. A new output column is created for each selected column; there is no option for in-place replacement of column values. One input column can be used to populate multiple output columns, just select the column again in the lower grid, using the Input Columns drop-down selector. Amend the output column name and size as required. They default to the same as the input column selected. Amend the behaviour as required, the default is Replace. Amend the cascade option as required, the default is true. Finally enter your match and replace regular expressions Quick Sample #1 Parse an email address and extract the user and domain portions. Format as a web address passing the user portion as a URL parameter. This uses two match groups, user and host, which correspond to the text before the @ and after it respectively. Behaviour is Emit, and cascade of false, we only have a single match expression. Match Expression ^(?<user>[^@]+)@(?<host>.+)$ Replace Expression - http://www.${host}?user=${user} Results Sample Input Sample Output [email protected] http://www.adventure-works.com?user=zheng0 The component is provided as an MSI file, however to complete the installation, you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the RegexClean Transformation from the list. Downloads The RegexClean Transformation is available for both SQL Server 2005 and SQL Server 2008. Please choose the version to match your SQL Server version, or you can install both versions and use them side by side if you have both SQL Server 2005 and SQL Server 2008 installed.

  • What's wrong with cplusplus.com?

    - by Kerrek SB
    This is perhaps not a perfectly suitable forum for this question, but let me give it a shot, at the risk of being moved away. There are several references for the C++ standard library, including the invaluable ISO standard, MSDN, IBM, cppreference, and cplusplus. Personally, when writing C++ I need a reference that has quick random access, short load times and usage examples, and I've been finding cplusplus.com pretty useful. However, I've been hearing negative opinions about that website frequently here on SO, so I would like to get specific: What are the errors, misconceptions or bad pieces of advice given by cplusplus.com? What are the risks of using it to make coding decisions? Let me add this point: I want to be able to answer questions here on SO with accurate quotes of the standard, and thus I would like to post immediately-usable links, and cplusplus.com would have been my choice site were it not for this issue. Update: There have been many great responses, and I have seriously changed my view on cplusplus.com. I'd like to list a few choice results here; feel free to suggest more (and keep posting answers). As of June 29, 2011: Incorrect description of some algorithms (e.g. remove). Information about the behaviour of functions is sometimes incorrect (atoi), fails to mention special cases (strncpy), or omits vital information (iterator invalidation). Examples contain deprecated code (#include style). Inexact terminology is doing a disservice to learners and the general community ("STL", "compiler" vs "toolchain"). Incorrect and misleading description of the typeid keyword.

I enabled detailed error message in IIS following this article: http://www.iis.net/learn/troubleshoot/diagnosing-http-errors/how-to-use-http-detailed-errors-in-iis I also checkec with Fiddler and see that I receive a 500 error: GET /wordpress/wp-admin/ HTTP/1.1 Host: www.mydomain.com Connection: keep-alive Cache-Control: max-age=0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36 Referer: http://www.mydomain.com/wordpress/wp-login.php Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8,nl;q=0.6 Cookie: wordpress_fabec4083cf12d8de89c98e8aef4b7e3=floran%7C1381236774%7C2d8edb4fc6618f290fadb49b035cad31; wordpress_test_cookie=WP+Cookie+check; wordpress_logged_in_fabec4083cf12d8de89c98e8aef4b7e3=floran%7C1381236774%7Cbf822163926b8b8df16d0f1fefb6e02e HTTP/1.1 500 Internal Server Error Content-Type: text/html Server: Microsoft-IIS/7.5 X-Powered-By: PHP/5.4.14 X-Powered-By: ASP.NET Date: Sun, 06 Oct 2013 12:56:03 GMT Content-Length: 0 My WordPress web.config in folder e:\mydomain\wwwroot\wordpress contains: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="wordpress" patternSyntax="Wildcard"> <match url="*"/> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/> </conditions> <action type="Rewrite" url="index.php"/> </rule></rules> </rewrite> </system.webServer> </configuration> I also want my WordPress articles to be available on www.mydomain.com/blog instead of www.mydomain.com/wordpress Ofcourse my admin links for Magento and Wordpress should also work.

  • No database selected error in CodeIgniter running on MAMP stack

    - by Apophenia Overload
    First off, does anyone know of a good place to get help with CodeIgniter? The official community forums are somewhat disappointing in terms of getting many responses. I have ci installed on a regular MAMP stack, and I’m working on this tutorial. However, I have only gone through the Created section, and currently I am getting a No database selected error. Model: <?php class submit_model extends Model { function submitForm($school, $district) { $data = array( 'school' => $school, 'district' => $district ); $this->db->insert('your_stats', $data); } } View: <?php $this->load->helper('form'); ?> <?php echo form_open('main'); ?> <p> <?php echo form_input('school'); ?> </p> <p> <?php echo form_input('district'); ?> </p> <p> <?php echo form_submit('submit', 'Submit'); ?> </p> <?php echo form_close(); ?> Controller: <?php class Main extends controller { function index() { // Check if form is submitted if ($this->input->post('submit')) { $school = $this->input->xss_clean($this->input->post('school')); $district = $this->input->xss_clean($this->input->post('district')); $this->load->model('submit_model'); // Add the post $this->submit_model->submitForm($school, $district); } $this->load->view('main_view'); } } database.php $db['default']['hostname'] = "localhost:8889"; $db['default']['username'] = "root"; $db['default']['password'] = "root"; $db['default']['database'] = "stats_test"; $db['default']['dbdriver'] = "mysql"; $db['default']['dbprefix'] = ""; $db['default']['pconnect'] = TRUE; $db['default']['db_debug'] = TRUE; $db['default']['cache_on'] = FALSE; $db['default']['cachedir'] = ""; $db['default']['char_set'] = "utf8"; $db['default']['dbcollat'] = "utf8_general_ci"; config.php $config['base_url'] = "http://localhost:8888/ci/"; ... $config['index_page'] = "index.php"; ... $config['uri_protocol'] = "AUTO"; So, how come it’s giving me this error message? A Database Error Occurred Error Number: 1046 No database selected INSERT INTO `your_stats` (`school`, `district`) VALUES ('TJHSST', 'FairFax') Is there any way for me to test if CodeIgniter can actually detect the mySQL databases I've created with phpMyAdmin in my MAMP stack?

  • How to properly deny Railo directory access through Apache

    - by Sn3akyP3t3
    I've been battle tested on this and failed to achieve my goal which is to deny all access to all directories except the Public directory and only allow access to all all other directories with specific IP addresses. To get Railo+Apache+Tomcat installed I pretty much followed this script: https://github.com/talltroym/Railo-Ubuntu-Installer-Script then verified settings with this tutorial: http://blog.nictunney.com/2012/03/railo-tomcat-and-apache-on-amazon-ec2.html From the installation script these mods are enabled: sudo a2enmod ssl sudo a2enmod proxy sudo a2enmod proxy_http sudo a2enmod rewrite sudo a2ensite default-ssl Outside of the script I copied the sites-available to sites-enabled then reloaded Apache. I have a directory created for Railo cmfl located at /var/www/Railo/ Navigating the browser to http ://Server_IP_Address/Railo forces ssl and relocates to https ://Server_IP_Address/Railo which shows off index.cfm. Not providing index.cfm and omitting https indicates that the DirectoryIndex directive and RewriteCond of Apache appears to be working for the sites-enabled VirtualHost. The problem I'm encountering is that I cannot seem to deny access to all directories except Public. My directory structure is rather simple and looks like this: Railo error Public NotPublic Sandbox These are my sites-enabled configurations: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www #Default Deny All to prevent walking backwards in file system Alias /Railo/ "/var/www/Railo/" <Directory ~ ".*/Railo/(?!Public).*"> Order Deny,Allow Deny from All </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

This means that # the standard Auth/DBMAuth methods can be used for access control. The # user name is the `one line' version of the client's X.509 certificate. # Note that no password is obtained from the user. Every entry in the user # file needs this password: `xxj31ZMTZzkVA'. # o ExportCertData: # This exports two additional environment variables: SSL_CLIENT_CERT and # SSL_SERVER_CERT. These contain the PEM-encoded certificates of the # server (always existing) and the client (only existing when client # authentication is used). This can be used to import the certificates # into CGI scripts. # o StdEnvVars: # This exports the standard SSL/TLS related `SSL_*' environment variables. # Per default this exportation is switched off for performance reasons, # because the extraction step is an expensive operation and is usually # useless for serving static content. So one usually enables the # exportation for CGI and SSI requests only. # o StrictRequire: # This denies access when "SSLRequireSSL" or "SSLRequire" applied even # under a "Satisfy any" situation, i.e. when it applies access is denied # and no other module can change it. # o OptRenegotiate: # This enables optimized SSL connection renegotiation handling when SSL # directives are used in per-directory context. #SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire <FilesMatch "\.(cgi|shtml|phtml|php)$"> SSLOptions +StdEnvVars </FilesMatch> <Directory /usr/lib/cgi-bin> SSLOptions +StdEnvVars </Directory> # SSL Protocol Adjustments: # The safe and default but still SSL/TLS standard compliant shutdown # approach is that mod_ssl sends the close notify alert but doesn't wait for # the close notify alert from client. When you need a different shutdown # approach you can use one of the following variables: # o ssl-unclean-shutdown: # This forces an unclean shutdown when the connection is closed, i.e. no # SSL close notify alert is send or allowed to received. This violates # the SSL/TLS standard but is needed for some brain-dead browsers. Use # this when you receive I/O errors because of the standard approach where # mod_ssl sends the close notify alert. # o ssl-accurate-shutdown: # This forces an accurate shutdown when the connection is closed, i.e. a # SSL close notify alert is send and mod_ssl waits for the close notify # alert of the client. This is 100% SSL/TLS standard compliant, but in # practice often causes hanging connections with brain-dead browsers. Use # this only for browsers where you know that their SSL implementation # works correctly. # Notice: Most problems of broken clients are also related to the HTTP # keep-alive facility, so you usually additionally want to disable # keep-alive for those clients, too. Use variable "nokeepalive" for this. # Similarly, one has to force some clients to use HTTP/1.0 to workaround # their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and # "force-response-1.0" for this. BrowserMatch "MSIE [2-6]" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 # MSIE 7 and newer should be able to use keepalive BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown DirectoryIndex index.cfm index.cfml default.cfm default.cfml index.htm index.html #Proxy .cfm and cfc requests to Railo ProxyPassMatch ^/(.+.cf[cm])(/.*)?$ http://127.0.0.1:8888/$1 ProxyPassReverse / http://127.0.0.1:8888/ #Deny access to admin except for local clients <Location /railo-context/admin/> Order deny,allow Deny from all # Allow from <Omitted> # Allow from <Omitted> Allow from 127.0.0.1 </Location> </VirtualHost> </IfModule> The apache2.conf includes the following: # Include the virtual host configurations: Include sites-enabled/ <IfModule !mod_jk.c> LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so </IfModule> <IfModule mod_jk.c> JkMount /*.cfm ajp13 JkMount /*.cfc ajp13 JkMount /*.do ajp13 JkMount /*.jsp ajp13 JkMount /*.cfchart ajp13 JkMount /*.cfm/* ajp13 JkMount /*.cfml/* ajp13 # Flex Gateway Mappings # JkMount /flex2gateway/* ajp13 # JkMount /flashservices/gateway/* ajp13 # JkMount /messagebroker/* ajp13 JkMountCopy all JkLogFile /var/log/apache2/mod_jk.log </IfModule> I believe I understand most of this except the jk_module inclusion which I've noticed has an error that shows up in the logs that I can't sort out: [warn] No JkShmFile defined in httpd.conf. Using default /etc/apache2/logs/jk-runtime-status I've checked my Regular expression against the paths of the directories with RegexBuddy just to be sure that I wasn't correct. The problem doesn't appear to be Regex related although I may have something incorrect in the Directory directive. The Location directive seems to be working correctly for blocking out Railo admin site access.

  • how to think like a computer scientist java edition exercise 7.2 [on hold]

    - by James Canfield
    I cannot figure out how to write this program, can someone please help me?! The purpose of this method is to practice manipulating St rings. Create a new program called Name.java. This program will take a name string consisting of EITHER a first name followed by a last name (nonstandar d format) or a last name followed by a comma then a first name (standard format). Ie . “Joe Smith” vs. “Smith, Joe”. This program will convert the string to standard format if it is not already in standard format. Write a method called hasComma that takes a name as an argument and that returns a boolean indicating whether it contains a comma. If i t does, you can assume that it is in last name first format. You can use the indexOf String m ethod to help you. Write a method called convertName that takes a name as an argument. It should check whether it contains a comma by calling your hasComma method. If it does, it should just return the string. If not, then it should assume th at the name is in first name first format, and it should return a new string that contains the name converted to last name comma first format. Uses charAt, length, substring, and indexOf methods. In your main program, loop, asking the user for a n ame string. If the string is not blank, call convertName and print the results. The loop terminat es when the string is blank. HINTS/SUGGESTIONS: Use the charAt, length, substring, and indexOf Str ing methods. Use scanner for your input. To get the full line, complete with spaces, use reader.nextLine()
