  • What is the best way to store static data in C# that will never changes

    - by Luke101
    I have a class that stores data in asp.net c# application that never changes. I really don't want to put this data in the database - I would like it to stay in the application. Here is my way to store data in the application: public class PostVoteTypeFunctions { private List<PostVoteType> postVotes = new List<PostVoteType>(); public PostVoteTypeFunctions() { PostVoteType upvote = new PostVoteType(); upvote.ID = 0; upvote.Name = "UpVote"; upvote.PointValue = PostVotePointValue.UpVote; postVotes.Add(upvote); PostVoteType downvote = new PostVoteType(); downvote.ID = 1; downvote.Name = "DownVote"; downvote.PointValue = PostVotePointValue.DownVote; postVotes.Add(downvote); PostVoteType selectanswer = new PostVoteType(); selectanswer.ID = 2; selectanswer.Name = "SelectAnswer"; selectanswer.PointValue = PostVotePointValue.SelectAnswer; postVotes.Add(selectanswer); PostVoteType favorite = new PostVoteType(); favorite.ID = 3; favorite.Name = "Favorite"; favorite.PointValue = PostVotePointValue.Favorite; postVotes.Add(favorite); PostVoteType offensive = new PostVoteType(); offensive.ID = 4; offensive.Name = "Offensive"; offensive.PointValue = PostVotePointValue.Offensive; postVotes.Add(offensive); PostVoteType spam = new PostVoteType(); spam.ID = 0; spam.Name = "Spam"; spam.PointValue = PostVotePointValue.Spam; postVotes.Add(spam); } } When the constructor is called the code above is ran. I have some functions that can query the data above too. But is this the best way to store information in asp.net? if not what would you recommend?

  • Scalable way to store files on server (PHP)?

    - by Nathaniel Bennett
    I'm creating my first web application - a really simplistic online text editor. What I need to do is find the best way to store text based files - a lot of them. These text files can be past 10,000 words in size (text words not computer words.) in essence I want the text documents to be limitless in size. I was thinking about storing the text files in my MySQL database - but thought there was a better way. Instead I'm planing on storing the text files in XML based format in a directory on my server. The rows in the database define the name of the xml based text file and the user who created the text along with basic metadata. An ID is generated using a V4 GUID generator , which gives the text an id and stores the text in the "/store" directory on my server. The text definitions in my server contain this id, and the android app I'm developing gets the contents of the text file by retrieving the text definition and then downloading the text to the local device using the GUID in the text definition. I just think this is a botch job? how can I improve this system? There has been cases of GUID colliding. I don't want this to happen. A "slim" possibility isn't good enough - I need to make sure there is absolutely no chance in a GUID collision. I was planning on checking the database for texts that have the same id before storing the text with a particular id - I however believe with over 20,000 pieces of text in my database this would take an long time and produce unneeded stress on the server. How can I make GUID safe? What happens when a GUID collides? The server backend is going to be written in PHP.

  • C++, using one byte to store two variables

    - by 2di
    Hi All I am working on representation of the chess board, and I am planning to store it in 32 bytes array, where each byte will be used to store two pieces. (That way only 4 bits are needed per piece) Doing it in that way, results in a overhead for accessing particular index of the board. Do you think that, this code can be optimised or completely different method of accessing indexes can be used? c++ char getPosition(unsigned char* c, int index){ //moving pointer c+=(index>>1); //odd number if (index & 1){ //taking right part return *c & 0xF; }else { //taking left part return *c>>4; } } void setValue(unsigned char* board, char value, int index){ //moving pointer board+=(index>>1); //odd number if (index & 1){ //replace right part //save left value only 4 bits *board = (*board & 0xF0) + value; }else { //replacing left part *board = (*board & 0xF) + (value<<4); } } int main() { char* c = (char*)malloc(32); for (int i = 0; i < 64 ; i++){ setValue((unsigned char*)c, i % 8,i); } for (int i = 0; i < 64 ; i++){ cout<<(int)getPosition((unsigned char*)c, i)<<" "; if (((i+1) % 8 == 0) && (i > 0)){ cout<<endl; } } return 0; } I am equally interested in your opinions regarding chess representations, and optimisation of the method above, as a stand alone problem. Thanks a lot

  • How to store arbitrary data for some HTML tags

    - by nickf
    I'm making a page which has some interaction provided by javascript. Just as an example: links which send an AJAX request to get the content of articles and then display that data in a div. Obviously in this example, I need each link to store an extra bit of information: the id of the article. The way I've been handling it in case was to put that information in the href link this: <a class="article" href="#5"> I then use jQuery to find the a.article elements and attach the appropriate event handler. (don't get too hung up on the usability or semantics here, it's just an example) Anyway, this method works, but it smells a bit, and isn't extensible at all (what happens if the click function has more than one parameter? what if some of those parameters are optional?) The immediately obvious answer was to use attributes on the element. I mean, that's what they're for, right? (Kind of). <a articleid="5" href="link/for/non-js-users.html"> In my recent question I asked if this method was valid, and it turns out that short of defining my own DTD (I don't), then no, it's not valid or reliable. A common response was to put the data into the class attribute (though that might have been because of my poorly-chosen example), but to me, this smells even more. Yes it's technically valid, but it's not a great solution. Another method I'd used in the past was to actually generate some JS and insert it into the page in a <script> tag, creating a struct which would associate with the object. var myData = { link0 : { articleId : 5, target : '#showMessage' // etc... }, link1 : { articleId : 13 } }; <a href="..." id="link0"> But this can be a real pain in butt to maintain and is generally just very messy. So, to get to the question, how do you store arbitrary pieces of information for HTML tags?

  • SQL SERVER – Fundamentals of Columnstore Index

    - by pinaldave
    There are two kind of storage in database. Row Store and Column Store. Row store does exactly as the name suggests – stores rows of data on a page – and column store stores all the data in a column on the same page. These columns are much easier to search – instead of a query searching all the data in an entire row whether the data is relevant or not, column store queries need only to search much lesser number of the columns. This means major increases in search speed and hard drive use. Additionally, the column store indexes are heavily compressed, which translates to even greater memory and faster searches. I am sure this looks very exciting and it does not mean that you convert every single index from row store to column store index. One has to understand the proper places where to use row store or column store indexes. Let us understand in this article what is the difference in Columnstore type of index. Column store indexes are run by Microsoft’s VertiPaq technology. However, all you really need to know is that this method of storing data is columns on a single page is much faster and more efficient. Creating a column store index is very easy, and you don’t have to learn new syntax to create them. You just need to specify the keyword “COLUMNSTORE” and enter the data as you normally would. Keep in mind that once you add a column store to a table, though, you cannot delete, insert or update the data – it is READ ONLY. However, since column store will be mainly used for data warehousing, this should not be a big problem. You can always use partitioning to avoid rebuilding the index. A columnstore index stores each column in a separate set of disk pages, rather than storing multiple rows per page as data traditionally has been stored. The difference between column store and row store approaches is illustrated below: In case of the row store indexes multiple pages will contain multiple rows of the columns spanning across multiple pages. In case of column store indexes multiple pages will contain multiple single columns. This will lead only the columns needed to solve a query will be fetched from disk. Additionally there is good chance that there will be redundant data in a single column which will further help to compress the data, this will have positive effect on buffer hit rate as most of the data will be in memory and due to same it will not need to be retrieved. Let us see small example of how columnstore index improves the performance of the query on a large table. As a first step let us create databaseset which is large enough to show performance impact of columnstore index. The time taken to create sample database may vary on different computer based on the resources. USE AdventureWorks GO -- Create New Table CREATE TABLE [dbo].[MySalesOrderDetail]( [SalesOrderID] [int] NOT NULL, [SalesOrderDetailID] [int] NOT NULL, [CarrierTrackingNumber] [nvarchar](25) NULL, [OrderQty] [smallint] NOT NULL, [ProductID] [int] NOT NULL, [SpecialOfferID] [int] NOT NULL, [UnitPrice] [money] NOT NULL, [UnitPriceDiscount] [money] NOT NULL, [LineTotal] [numeric](38, 6) NOT NULL, [rowguid] [uniqueidentifier] NOT NULL, [ModifiedDate] [datetime] NOT NULL ) ON [PRIMARY] GO -- Create clustered index CREATE CLUSTERED INDEX [CL_MySalesOrderDetail] ON [dbo].[MySalesOrderDetail] ( [SalesOrderDetailID]) GO -- Create Sample Data Table -- WARNING: This Query may run upto 2-10 minutes based on your systems resources INSERT INTO [dbo].[MySalesOrderDetail] SELECT S1.* FROM Sales.SalesOrderDetail S1 GO 100 Now let us do quick performance test. I have kept STATISTICS IO ON for measuring how much IO following queries take. In my test first I will run query which will use regular index. We will note the IO usage of the query. After that we will create columnstore index and will measure the IO of the same. -- Performance Test -- Comparing Regular Index with ColumnStore Index USE AdventureWorks GO SET STATISTICS IO ON GO -- Select Table with regular Index SELECT ProductID, SUM(UnitPrice) SumUnitPrice, AVG(UnitPrice) AvgUnitPrice, SUM(OrderQty) SumOrderQty, AVG(OrderQty) AvgOrderQty FROM [dbo].[MySalesOrderDetail] GROUP BY ProductID ORDER BY ProductID GO -- Table 'MySalesOrderDetail'. Scan count 1, logical reads 342261, physical reads 0, read-ahead reads 0. -- Create ColumnStore Index CREATE NONCLUSTERED COLUMNSTORE INDEX [IX_MySalesOrderDetail_ColumnStore] ON [MySalesOrderDetail] (UnitPrice, OrderQty, ProductID) GO -- Select Table with Columnstore Index SELECT ProductID, SUM(UnitPrice) SumUnitPrice, AVG(UnitPrice) AvgUnitPrice, SUM(OrderQty) SumOrderQty, AVG(OrderQty) AvgOrderQty FROM [dbo].[MySalesOrderDetail] GROUP BY ProductID ORDER BY ProductID GO It is very clear from the results that query is performance extremely fast after creating ColumnStore Index. The amount of the pages it has to read to run query is drastically reduced as the column which are needed in the query are stored in the same page and query does not have to go through every single page to read those columns. If we enable execution plan and compare we can see that column store index performance way better than regular index in this case. Let us clean up the database. -- Cleanup DROP INDEX [IX_MySalesOrderDetail_ColumnStore] ON [dbo].[MySalesOrderDetail] GO TRUNCATE TABLE dbo.MySalesOrderDetail GO DROP TABLE dbo.MySalesOrderDetail GO In future posts we will see cases where Columnstore index is not appropriate solution as well few other tricks and tips of the columnstore index.

  • Windows system restore deletes various executables and *.js files. How does it decide which files to delete?

    - by Leftium
    I restored my system from a Windows System Restore point. It solved some issues I was having, but introduced other strange problems (like my optical drive disappeared). One thing that surprised me was several files from my Web2Py installation were deleted: the executables and *.js files; possibly some others (like favicon.ico). I did not expect this because Web2Py is basically a portable, standalone application. You just unzip it and run the executable inside, so nothing should be registered with Windows. My question is: what files does Windows system restore delete, and how does it decide this? I'm just wondering what other files I'm missing and if there's a way to get restore them (without rolling back the restore point). Perhaps it scans for certain files types (like exe, js, ico, dll) with a creation date that was after the restore point creation date? Some other people who experienced a similar problem: Dropbox: Lost Files User files missing after run system restore. update: I found some more references on how Windows System Restore works: Understanding how System Restore in Windows Vista treats executable files Why Vista's System Restore is Dangerous and What to do About it

  • Supermicro IPMI on MBD-X8DAH+-F-O motherboard. Keyboard and mouse do not work after booting Windows Server 2008 R2

    - by LDelgado
    Hell Everyone, I built a server with the mentioned motherboard. I installed Windows Server 2008 R2 Enterprise on this server. IPMI is integrated on the motherboard with its own dedicated NIC. I've got that NIC configured with its own IP address. I can remote into it using IPMI, and I can remotely control the server settings before booting the OS ( BIOS, RAID configuration, etc). When the OS boots, I lose the mouse and keyboard. I cannot use the keyboard or mouse when installing the OS either. So the Keyboard and Mouse only work when no OS is loaded. Once the OS loads I lose it - that is my problem. I've been doing some research and trying a few things, but I have not been successful in fixing this issue. I may be wrong, but based on the things I've found online, it seems that the problem could be caused by the way the OS handles USB. The server is headless. There is no keyboard, mouse, or monitor plugged into it. When I boot up the OS and remote into it, I cannot see a mouse or keyboard listed in the Device Manager. Based on what I've read, it seems that the OS should detect a mouse and a keyboard when connecting remotely via IPMI. The following are the solutions I've tried. Nothing has worked so far: I've updated the firmware of the IPMI component to the latest firmware - 1.33. I made sure that the mouse mode was set to Absolute (Windows OS). I've loaded the factory defaults several times. I've enabled Port64h/60h Emulation under the USB settings in the BIOS. I've disabled USB legacy support in the BIOS. I made sure the firewall wasn't blocking IPMI (disabled the firewall). And that's about it. I've found threads in some forums from people having the same issue as me, but they were not running the same OS. They were either running Linux or FreeBSD. Most of them fixed their problem by selecting the right mouse mode (Linux in their case). There was one other that solved the problem by disabling USB Mass Storage mode. He stated "When I set it to disable USB Mass Storage when no image is loaded, the ukbd came alive, and I'm typing this on the IPMI Console. " source: http://freebsd.1045724.n5.nabble.com/IPMI-Console-No-luck-once-OS-is-booted-td3967868.html I suspect the solution described in the previous paragraph is somehow related to my problem. I've found several threads on the internet with issues describing the same problem, but none of them were with Windows Server 2008 R2. Again, I may be wrong, but it seems like that could be the issue. I just don't know how I go about applying a solution in Windows Server 2008 R2. In any case, I could use your expertise. Maybe I am missing something, or maybe I'm on the right track. Your help is much appreciated. Thank you in advance,

  • Stop Windows 7 from accessing or writing to hard drive unless "told" to by me? (More info inside...)

    - by Jeff
    A confusing question, perhaps, but bear with me. I have two internal HDDs set up in a RAID0 array which I use as mass storage. I access the drive very infrequently (once a day at most) and so I have set up Windows 7's power options to turn off idle disks after only 1 minute. This is fine, and the disks are turned off most of the time. However, I notice that Windows sometimes spins up the drives when I really, really don't want or need it to. This causes a 30 second delay as both drives spin up and lock up my system. Some examples of when this happens: 1) When I'm installing something using Windows Installer or Installshield; it seems to me as if they're using the drive with most available free space as the installer cache location... so my big RAID drive has to spin up! Most annoying. 2) Apparently, when I open a Java-based program which resides on my system drive and has nothing to do with my RAID drive! 3) At boot-up and shut-down time. At shutdown the drive spin up only for the computer to immediately shut down! Incredibly frustrating! I've already tried changing the letter of the drive, and at some points have removed the drive letter entirely, which solves the first two issues above. So my question (FINALLY!) is this: is there any way I can mark this drive as being for "storage only", so Windows basically does not see it at all until I actually invoke it somehow? Or is there any way I could set it up so that only specific programs have write access to it? For example, download managers, TeraCopy, etc. etc.? Basically I want it to be a "ghost drive" until I'm ready to use it and to stop Windows from spinning it up all the damn time! Thank you. :)

  • I'm having two Windows 7 installed and running in my laptop. How can I delete the other one?

    - by mandy
    I have another concern with my laptop. When I had a problem with the microphone, I tried to restore the system. But sadly, I had a mistake with the process and accidentally it was formatted. Its a built in laptop. (Toshiba m840, Windows 7, 64 bit) After the format process, programs were automatically installed. Until a friend of mine told me that I might have 2 Windows installed already. When we checked the program, he was right. I'm having 2 program files folders, which means I really have 2 Windows installed and running in my laptop. Supposed to be, there should be only 1 right? Can anyone help me how to delete the other Windows? Because I think it is occupying much space in the hard drive. They say it could make my laptop become slower.

  • How to create a high quality icon for my Windows application?

    - by Patrick Klug
    If you are running Windows with a higher DPI setting you will notice that most application icons on the desktop look terrible. Even high profile application icons such as Google Chrome look terrible while for example Firefox, Skype and MS Office icons look sharp: (example) I suspect that most icons look blurry because a lower resolution icon is scaled up rather than using a higher resolution icon. I want to give my application a high quality icon and can't seem to convince Windows to use the higher resolution icon. I have created a multi-resolution icon with the free icon editor IcoFX. The icon is provided in 16x16, 24x24, 32x32,48x48, 128x128 and 256x256 (!) (all in 32 bit including alpha channel) yet Windows seems to use the 128x128 version of the icon on the desktop and scale it up which looks terrible. (I am using Windows 7 - 64 bit - the icon is placed by means of setting up a shortcut in the msi (created via Visual Studio 2008 Setup Project) and pointing it to the .ico file that contains the multi-resolution icon) I have tried removing the 128x128 icon but to no avail. Interestingly in Windows Explorer the icon looks great even when using the Extra Large Icon setting. How can I create a high quality desktop icon that looks great on higher DPI settings on Windows?

  • What's the vbs code to schedule a task every time Windows starts up?

    - by Wing C. Chen
    I would like to know how to write up the vbs code to schedule a windows task to start a .exe program every time the Windows starts up. I found the following code online: strComputer = "." Set objWMIService = GetObject("winmgmts:" _ & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2") Set objNewJob = objWMIService.Get("Win32_ScheduledJob") errJobCreated = objNewJob.Create _ ("Notepad.exe", "********123000.000000-420", _ True , 1 OR 4 OR 16, , , JobID) Wscript.Echo errJobCreated But it only tells me how to schedule the task every on some specific days and hours. I thought of creating a windows service. However the following is the story why I must look for an alternative to it. I created a windows service with RunAsService for my java program wrapped with Janel. The Service worked fine when I first installed and started it. However, after restarting my windows xp, a dialog window poped out saying that my janel generated .exe file has crashed, with my RunAsService service kept on going. The service worked fine when I terminated the service and restarted it again manually. Nevertheless, the same crash happens over and over again every time I restart my Windows.

  • Disk Error on Boot (Possible boot sector issue)

    - by Choco
    I own a 4-5 year old Dell Dimension E510 with Windows XP: Media Center Edition. I have 2 drives installed: C Drive: Windows XP: Media Center Edition G Drive: 2 partitions: Windows 7 (beta) Windows XP (professional) That is also the order they are connected. The C Drive is my primary drive. When I attempt to boot the computer, the bios loading screen appears normally; the progress bar moves and it's fine. The very next page, however, supposed to be a boot choice. When I installed Windows 7 onto the G Drive in context of the C drive it added a boot selector to the C drive's boot sequence. It gives me the option of booting Windows 7 or Windows XP: Media Center Edition. However, my problem is now this: After the bios screen I previously mentioned, instead of a boot selector, I receive the following error: A disk read error occurred. Press CTRL+ALT+DEL to restart. The drive is spinning up normally. I hear no odd noises/clicks/scraping coming from it, even after disabling the other drive to listen to it carefully. According to me, it's a boot sector issue. I have never experienced this before, but maybe during a recent shutdown, Windows XP: MCE errored out and ruined the boot sector. Dilemma! I don't have the Windows XP: MCE disc, because it was installed by the factory. I have accessed the hidden partition on the drive before (you hit a key combination on the bios screen and it comes up with an interface to fix your drive). However, I don't want to reformat the drive (which is what the interface gives me the option to do). I want to possibly fix the boot sector. How can I achieve that?

  • Deleting "undeletable" files in Vista

    - by Nik Reiman
    I recently upgraded my workstation from XP SP3 to Vista Business, and during the upgrade Windows moved my old C:\Windows directory to C:\Windows.old. I got all of the stuff I needed out of that folder, but there are six "undeletable" files there so I cannot remove it. They are: Windows.old\Program1\Adobe\Reader 9.0\Resource\CMap\Identity-H Windows.old\Program1\Adobe\Reader 9.0\Resource\CMap\Identity-V Windows.old\Program1\Common Files\Adobe\Acrobat\ActiveX\AcroIEHelper.dll Windows.old\Program1\Common Files\Adobe\Acrobat\ActiveX\AcroIEHelperShim.dll Windows.old\Program1\Common Files\Adobe\Acrobat\ActiveX\AcroPDF.dll Windows.old\Program1\Common Files\Adobe\Acrobat\ActiveX\pdfshell.dll Whenever I try to delete the files either through explorer or a command line, I get a permission denied error. I have tried to grant myself full permission on the files, but again, permission denied. I don't even have acrobat installed on my Vista machine, and I uninstalled Adobe updater. However, I still can't manage to get rid of these files. How do I nuke them for good? Edit: I was able to take ownership of the files, but I still can't delete them. Renaming them did not work, as I was denied permission to do that as well. I'll try booting up in safe mode and getting rid of them there. Edit II: Booting up into safe mode did not allow me to delete the files. Bummer.

  • Routing for remote gateway over VPN in Vista/7 broken?

    - by Raymond
    Hi, Situation is as follows. Home computer running Windows 7, sets up VPN connection (LT2P + IPSec, "use remote gateway" disabled) to office. Subnet is 192.168.64.x Office has Draytek Vigor 2920 router, subnet is 192.168.32.x What happens? - VPN connection itself works fine - Can ping any machine on the remote network - When trying to open a webpage from a host in the remote network, the remote server logs the incoming request, but the browser hangs on "waiting for..." and eventually times out. I have observed this problem on Windows Vista and Windows 7. On Windows XP however there is no problem like described above. The only clue I have is that there is a difference in the routing between XP and Vista/7. The output of "route print" on Windows XP looks like this: (See www.latunyi.com/routing_xp.png) So here the gateway for the 192.168.32.x subnet is the IP address that the local computer has in the remote network. The output of "route print" on Windows 7 (and Windows Vista) looks like this: (See www.latunyi.com/routing_win7.png") Now the gateway for the 192.168.32.x subnet is the IP address of the VPN router (32.1). I don't know if that causes this trouble, but it seems a bit strange. Enabling "use default gateway on remote network" doesn't make a difference. Using the new option "Disable class based route addition" in Windows 7 only makes the route to the VPN router disappear. I am really puzzled here. I assume the VPN routing can't be broken in both Vista and Windows 7, and this should just work without manually adding routes. I hope someone has a solution for this problem :-). Thanks!

  • disk write cache buffer and separate power supply

    - by HugoRune
    Windows has a setting to turn off the write-cache buffer (see image) Turn off Windows write-cache buffer flushing on the device To prevent data loss, do not select this check box unless the device has a separate power supply that allows the device to flush its buffer in case of power failure. Is it feasible and economical to get such a "separate power supply" for the internal sata drives of a non-server PC? Under what name is such a power supply sold? I know that there are UPS devices that can be connected to external drives,but what is required to be able to switch this setting safely on for an internal disk? The setting has different descriptions in different version of windows Windows XP: Enable write caching on the disk This setting enables write caching in Windows to improve disk performance, but a power outage or equipment failure might result in data loss or corruption. Windows Server 2003: Enable write caching on the disk Recommended only for disks with a backup power supply. This setting further improves disk performance, but it also increases the risk of data loss if the disk loses power. Windows Vista: Enable advanced performance Recommended only for disks with a backup power supply. This setting further improves disk performance, but it also increases the risk of data loss if the disk loses power. Windows 7 and 8: Turn off Windows write-cache buffer flushing on the device To prevent data loss, do not select this check box unless the device has a separate power supply that allows the device to flush its buffer in case of power failure. This article by Raymond Chen has some more detailed information about what the setting does.

  • Calling a Stored Procedure using C# with XML Datatype

    - by Lakeshore
    I am simply trying to call a store procedure (SQL Server 2008) using C# and passing XMLDocument to a store procedure parameter that takes a SqlDbType.Xml data type.

  • Windows 7 can't copy file - Error 0x800700DF: The file size exceeds the limit allowed and cannot be

    - by JJGroover
    Any attempt to copy files larger than about 40 MB from a network share (a SAN running open filer / Samba) to my local machine running Windows 7 always results in the following error and the copy fails: Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved. I've tried copying to my C: drive and a USB drive with the same results. Smaller files copy just fine. Clearly 40 MB is not that big of a file so I'm assuming it is some buggy interaction between windows 7 and Samba perhaps. Google has so far turned up nothing. Can anyone point me in the right direction?

  • Continual "The Windows Filtering Platform has blocked a connection" errors?

    - by Richard
    Our systems have been compromised by something recently which has lead us to carry out a more detailed look at what is happening on our workstations. I have noticed an issue where the Security log of this Windows 7 workstation is continually logging a security "Audit Failure" where the detail is that "The Windows Filtering Platform has blocked a connection". This is happening thousands of times a day and would appear to be our BT Business Broadband HGV 2700 ADSL router attempting to connect to Port 137 (NET Bios) on my workstation and being blocked. This has unfortunately had the effect of filling up the log files so much that anything which might have been of use which was logged over the weekend to help debug the intrusion has been "overwritten off the end" of the Security log. (I've since increased the log file size limits massively and turned on archiving). Does anyone know if this is standard behaviour of a BT ADSL router or whether this indicates that the router is compromised in some way or malfunctioning, or have any further suggestions as to how to diagnose this problem?

  • Azure - Part 4 - Table Storage Service in Windows Azure

    - by Shaun
    In Windows Azure platform there are 3 storage we can use to save our data on the cloud. They are the Table, Blob and Queue. Before the Chinese New Year Microsoft announced that Azure SDK 1.1 had been released and it supports a new type of storage – Drive, which allows us to operate NTFS files on the cloud. I will cover it in the coming few posts but now I would like to talk a bit about the Table Storage.   Concept of Table Storage Service The most common development scenario is to retrieve, create, update and remove data from the data storage. In the normal way we communicate with database. When we attempt to move our application over to the cloud the most common requirement should be have a storage service. Windows Azure provides a in-build service that allow us to storage the structured data, which is called Windows Azure Table Storage Service. The data stored in the table service are like the collection of entities. And the entities are similar to rows or records in the tradtional database. An entity should had a partition key, a row key, a timestamp and set of properties. You can treat the partition key as a group name, the row key as a primary key and the timestamp as the identifer for solving the concurrency problem. Different with a table in a database, the table service does not enforce the schema for tables, which means you can have 2 entities in the same table with different property sets. The partition key is being used for the load balance of the Azure OS and the group entity transaction. As you know in the cloud you will never know which machine is hosting your application and your data. It could be moving based on the transaction weight and the number of the requests. If the Azure OS found that there are many requests connect to your Book entities with the partition key equals “Novel” it will move them to another idle machine to increase the performance. So when choosing the partition key for your entities you need to make sure they indecate the category or gourp information so that the Azure OS can perform the load balance as you wish.   Consuming the Table Although the table service looks like a database, you cannot access it through the way you are using now, neither ADO.NET nor ODBC. The table service exposed itself by ADO.NET Data Service protocol, which allows you can consume it through the RESTful style by Http requests. The Azure SDK provides a sets of classes for us to connect it. There are 2 classes we might need: TableServiceContext and TableServiceEntity. The TableServiceContext inherited from the DataServiceContext, which represents the runtime context of the ADO.NET data service. It provides 4 methods mainly used by us: CreateQuery: It will create a IQueryable instance from a given type of entity. AddObject: Add the specified entity into Table Service. UpdateObject: Update an existing entity in the Table Service. DeleteObject: Delete an entity from the Table Service. Beofre you operate the table service you need to provide the valid account information. It’s something like the connect string of the database but with your account name and the account key when you created the storage service on the Windows Azure Development Portal. After getting the CloudStorageAccount you can create the CloudTableClient instance which provides a set of methods for using the table service. A very useful method would be CreateTableIfNotExist. It will create the table container for you if it’s not exsited. And then you can operate the eneities to that table through the methods I mentioned above. Let me explain a bit more through an exmaple. We always like code rather than sentence.   Straightforward Accessing to the Table Here I would like to build a WCF service on the Windows Azure platform, and for now just one requirement: it would allow the client to create an account entity on the table service. The WCF service would have a method named Register and accept an instance of the account which the client wants to create. After perform some validation it will add the entity into the table service. So the first thing I should do is to create a Cloud Application on my VIstial Studio 2010 RC. (The Azure SDK 1.1 only supports VS2008 and VS2010 RC.) The solution should be like this below. Then I added a configuration items for the storage account through the Settings section under the cloud project. (Double click the Services file under Roles folder and navigate to the Setting section.) This setting will be used when to retrieve my storage account information. Since for now I just in the development phase I will select “UseDevelopmentStorage=true”. And then I navigated to the WebRole.cs file under my WCF project. If you have read my previous posts you would know that this file defines the process when the application start, and terminate on the cloud. What I need to do is to when the application start, set the configuration publisher to load my config file with the config name I specified. So the code would be like below. I removed the original service and contract created by the VS template and add my IAccountService contract and its implementation class - AccountService. And I add the service method Register with the parameters: email, password and it will return a boolean value to indicates the result which is very simple. At this moment if I press F5 the application will be established on my local development fabric and I can see my service runs well through the browser. Let’s implement the service method Rigister, add a new entity to the table service. As I said before the entities you want to store in the table service must have 3 properties: partition key, row key and timespan. You can create a class with these 3 properties. The Azure SDK provides us a base class for that named TableServiceEntity in Microsoft.WindowsAzure.StorageClient namespace. So what we need to do is more simply, create a class named Account and let it derived from the TableServiceEntity. And I need to add my own properties: Email, Password, DateCreated and DateDeleted. The DateDeleted is a nullable date time value to indecate whether this entity had been deleted and when. Do you notice that I missed something here? Yes it’s the partition key and row key I didn’t assigned. The TableServiceEntity base class defined 2 constructors one was a parameter-less constructor which will be used to fill values into the properties from the table service when retrieving data. The other was one with 2 parameters: partition key and row key. As I said below the partition key may affect the load balance and the row key must be unique so here I would like to use the email as the parition key and the email plus a Guid as the row key. OK now we finished the entity class we need to store onto the table service. The next step is to create a data access class for us to add it. Azure SDK gives us a base class for it named TableServiceContext as I mentioned below. So let’s create a class for operate the Account entities. The TableServiceContext need the storage account information for its constructor. It’s the combination of the storage service URI that we will create on Windows Azure platform, and the relevant account name and key. The TableServiceContext will use this information to find the related address and verify the account to operate the storage entities. Hence in my AccountDataContext class I need to override this constructor and pass the storage account into it. All entities will be saved in the table storage with one or many tables which we call them “table containers”. Before we operate an entity we need to make sure that the table container had been created on the storage. There’s a method we can use for that: CloudTableClient.CreateTableIfNotExist. So in the constructor I will perform it firstly to make sure all method will be invoked after the table had been created. Notice that I passed the storage account enpoint URI and the credentials to specify where my storage is located and who am I. Another advise is that, make your entity class name as the same as the table name when create the table. It will increase the performance when you operate it over the cloud especially querying. Since the Register WCF method will add a new account into the table service, here I will create a relevant method to add the account entity. Before implement, I should add a reference - System.Data.Services.Client to the project. This reference provides some common method within the ADO.NET Data Service which can be used in the Windows Azure Table Service. I will use its AddObject method to create my account entity. Since the table service are not fully implemented the ADO.NET Data Service, there are some methods in the System.Data.Services.Client that TableServiceContext doesn’t support, such as AddLinks, etc. Then I implemented the serivce method to add the account entity through the AccountDataContext. You can see in the service implmentation I load the storage account information through my configuration file and created the account table entity from the parameters. Then I created the AccountDataContext. If it’s my first time to invoke this method the constructor of the AccountDataContext will create a table container for me. Then I use Add method to add the account entity into the table. Next, let’s create a farely simple client application to test this service. I created a windows console application and added a service reference to my WCF service. The metadata information of the WCF service cannot be retrieved if it’s deployed on the Windows Azure even though the <serviceMetadata httpGetEnabled="true"/> had been set. If we need to get its metadata we can deploy it on the local development service and then changed the endpoint to the address which is on the cloud. In the client side app.config file I specified the endpoint to the local development fabric address. And the just implement the client to let me input an email and a password then invoke the WCF service to add my acocunt. Let’s run my application and see the result. Of course it should return TRUE to me. And in the local SQL Express I can see the data had been saved in the table.   Summary In this post I explained more about the Windows Azure Table Storage Service. I also created a small application for demostration of how to connect and consume it through the ADO.NET Data Service Managed Library provided within the Azure SDK. I only show how to create an eneity in the storage service. In the next post I would like to explain about how to query the entities with conditions thruogh LINQ. I also would like to refactor my AccountDataContext class to make it dyamic for any kinds of entities.   Hope this helps, Shaun   All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

  • Azure Grid Computing - Worker Roles as HPC Compute Nodes

    - by JoshReuben
    Overview ·        With HPC 2008 R2 SP1 You can add Azure worker roles as compute nodes in a local Windows HPC Server cluster. ·        The subscription for Windows Azure like any other Azure Service - charged for the time that the role instances are available, as well as for the compute and storage services that are used on the nodes. ·        Win-Win ? - Azure charges the computer hour cost (according to vm size) amortized over a month – so you save on purchasing compute node hardware. Microsoft wins because you need to purchase HPC to have a local head node for managing this compute cluster grid distributed in the cloud. ·        Blob storage is used to hold input & output files of each job. I can see how Parametric Sweep HPC jobs can be supported (where the same job is run multiple times on each node against different input units), but not MPI.NET (where different HPC Job instances function as coordinated agents and conduct master-slave inter-process communication), unless Azure is somehow tunneling MPI communication through inter-WorkerRole Azure Queues. ·        this is not the end of the story for Azure Grid Computing. If MS requires you to purchase a local HPC license (and administrate it), what's to stop a 3rd party from doing this and encapsulating exposing HPC WCF Broker Service to you for managing compute nodes? If MS doesn’t  provide head node as a service, someone else will! Process ·        requires creation of a worker node template that specifies a connection to an existing subscription for Windows Azure + an availability policy for the worker nodes. ·        After worker nodes are added to the cluster, you can start them, which provisions the Windows Azure role instances, and then bring them online to run HPC cluster jobs. ·        A Windows Azure worker role instance runs a HPC compatible Azure guest operating system which runs on the VMs that host your service. The guest operating system is updated monthly. You can choose to upgrade the guest OS for your service automatically each time an update is released - All role instances defined by your service will run on the guest operating system version that you specify. see Windows Azure Guest OS Releases and SDK Compatibility Matrix (http://go.microsoft.com/fwlink/?LinkId=190549). ·        use the hpcpack command to upload file packages and install files to run on the worker nodes. see hpcpack (http://go.microsoft.com/fwlink/?LinkID=205514). Requirements ·        assuming you have an azure subscription account and the HPC head node installed and configured. ·        Install HPC Pack 2008 R2 SP 1 -  see Microsoft HPC Pack 2008 R2 Service Pack 1 Release Notes (http://go.microsoft.com/fwlink/?LinkID=202812). ·        Configure the head node to connect to the Internet - connectivity is provided by the connection of the head node to the enterprise network. You may need to configure a proxy client on the head node. Any cluster network topology (1-5) is supported). ·        Configure the firewall - allow outbound TCP traffic on the following ports: 80,       443, 5901, 5902, 7998, 7999 ·        Note: HPC Server  uses Admin Mode (Elevated Privileges) in Windows Azure to give the service administrator of the subscription the necessary privileges to initialize HPC cluster services on the worker nodes. ·        Obtain a Windows Azure subscription certificate - the Windows Azure subscription must be configured with a public subscription (API) certificate -a valid X.509 certificate with a key size of at least 2048 bits. Generate a self-sign certificate & upload a .cer file to the Windows Azure Portal Account page > Manage my API Certificates link. see Using the Windows Azure Service Management API (http://go.microsoft.com/fwlink/?LinkId=205526). ·        import the certificate with an associated private key on the HPC cluster head node - into the trusted root store of the local computer account. Obtain Windows Azure Connection Information for HPC Server ·        required for each worker node template ·        copy from azure portal - Get from: navigation pane > Hosted Services > Storage Accounts & CDN ·        Subscription ID - a 32-char hex string in the form xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. In Properties pane. ·        Subscription certificate thumbprint - a 40-char hex string (you need to remove spaces). In Management Certificates > Properties pane. ·        Service name - the value of <ServiceName> configured in the public URL of the service (http://<ServiceName>.cloudapp.net). In Hosted Services > Properties pane. ·        Blob Storage account name - the value of <StorageAccountName> configured in the public URL of the account (http://<StorageAccountName>.blob.core.windows.net). In Storage Accounts > Properties pane. Import the Azure Subscription Certificate on the HPC Head Node ·        enable the services for Windows HPC Server  to authenticate properly with the Windows Azure subscription. ·        use the Certificates MMC snap-in to import the certificate to the Trusted Root Certification Authorities store of the local computer account. The certificate must be in PFX format (.pfx or .p12 file) with a private key that is protected by a password. ·        see Certificates (http://go.microsoft.com/fwlink/?LinkId=163918). ·        To open the certificates snapin: Run > mmc. File > Add/Remove Snap-in > certificates > Computer account > Local Computer ·        To import the certificate via wizard - Certificates > Trusted Root Certification Authorities > Certificates > All Tasks > Import ·        After the certificate is imported, it appears in the details pane in the Certificates snap-in. You can open the certificate to check its status. Configure a Proxy Client on the HPC Head Node ·        the following Windows HPC Server services must be able to communicate over the Internet (through the firewall) with the services for Windows Azure: HPCManagement, HPCScheduler, HPCBrokerWorker. ·        Create a Windows Azure Worker Node Template ·        Edit HPC node templates in HPC Node Template Editor. ·        Specify: 1) Windows Azure subscription connection info (unique service name) for adding a set of worker nodes to the cluster + 2)worker node availability policy – rules for deploying / removing worker role instances in Windows Azure o   HPC Cluster Manager > Configuration > Navigation Pane > Node Templates > Actions pane > New à Create Node Template Wizard or Edit à Node Template Editor o   Choose Node Template Type page - Windows Azure worker node template o   Specify Template Name page – template name & description o   Provide Connection Information page – Azure Subscription ID (text) & Subscription certificate (browse) o   Provide Service Information page - Azure service name + blob storage account name (optionally click Retrieve Connection Information to get list of available from azure – possible LRT). o   Configure Azure Availability Policy page - how Windows Azure worker nodes start / stop (online / offline the worker role instance -  add / remove) – manual / automatic o   for automatic - In the Configure Windows Azure Worker Availability Policy dialog -select days and hours for worker nodes to start / stop. ·        To validate the Windows Azure connection information, on the template's Connection Information tab > Validate connection information. ·        You can upload a file package to the storage account that is specified in the template - eg upload application or service files that will run on the worker nodes. see hpcpack (http://go.microsoft.com/fwlink/?LinkID=205514). Add Azure Worker Nodes to the HPC Cluster ·        Use the Add Node Wizard – specify: 1) the worker node template, 2) The number of worker nodes   (within the quota of role instances in the azure subscription), and 3)           The VM size of the worker nodes : ExtraSmall, Small, Medium, Large, or ExtraLarge.  ·        to add worker nodes of different sizes, must run the Add Node Wizard separately for each size. ·        All worker nodes that are added to the cluster by using a specific worker node template define a set of worker nodes that will be deployed and managed together in Windows Azure when you start the nodes. This includes worker nodes that you add later by using the worker node template and, if you choose, worker nodes of different sizes. You cannot start, stop, or delete individual worker nodes. ·        To add Windows Azure worker nodes o   In HPC Cluster Manager: Node Management > Actions pane > Add Node à Add Node Wizard o   Select Deployment Method page - Add Azure Worker nodes o   Specify New Nodes page - select a worker node template, specify the number and size of the worker nodes ·        After you add worker nodes to the cluster, they are in the Not-Deployed state, and they have a health state of Unapproved. Before you can use the worker nodes to run jobs, you must start them and then bring them online. ·        Worker nodes are numbered consecutively in a naming series that begins with the root name AzureCN – this is non-configurable. Deploying Windows Azure Worker Nodes ·        To deploy the role instances in Windows Azure - start the worker nodes added to the HPC cluster and bring the nodes online so that they are available to run cluster jobs. This can be configured in the HPC Azure Worker Node Template – Azure Availability Policy -  to be automatic or manual. ·        The Start, Stop, and Delete actions take place on the set of worker nodes that are configured by a specific worker node template. You cannot perform one of these actions on a single worker node in a set. You also cannot perform a single action on two sets of worker nodes (specified by two different worker node templates). ·        ·          Starting a set of worker nodes deploys a set of worker role instances in Windows Azure, which can take some time to complete, depending on the number of worker nodes and the performance of Windows Azure. ·        To start worker nodes manually and bring them online o   In HPC Node Management > Navigation Pane > Nodes > List / Heat Map view - select one or more worker nodes. o   Actions pane > Start – in the Start Azure Worker Nodes dialog, select a node template. o   the state of the worker nodes changes from Not Deployed to track the provisioning progress – worker node Details Pane > Provisioning Log tab. o   If there were errors during the provisioning of one or more worker nodes, the state of those nodes is set to Unknown and the node health is set to Unapproved. To determine the reason for the failure, review the provisioning logs for the nodes. o   After a worker node starts successfully, the node state changes to Offline. To bring the nodes online, select the nodes that are in the Offline state > Bring Online. ·        Troubleshooting o   check node template. o   use telnet to test connectivity: telnet <ServiceName>.cloudapp.net 7999 o   check node status - Deployment status information appears in the service account information in the Windows Azure Portal - HPC queries this -  see  node status information for any failed nodes in HPC Node Management. ·        When role instances are deployed, file packages that were previously uploaded to the storage account using the hpcpack command are automatically installed. You can also upload file packages to storage after the worker nodes are started, and then manually install them on the worker nodes. see hpcpack (http://go.microsoft.com/fwlink/?LinkID=205514). ·        to remove a set of role instances in Windows Azure - stop the nodes by using HPC Cluster Manager (apply the Stop action). This deletes the role instances from the service and changes the state of the worker nodes in the HPC cluster to Not Deployed. ·        Each time that you start a set of worker nodes, two proxy role instances (size Small) are configured in Windows Azure to facilitate communication between HPC Cluster Manager and the worker nodes. The proxy role instances are not listed in HPC Cluster Manager after the worker nodes are added. However, the instances appear in the Windows Azure Portal. The proxy role instances incur charges in Windows Azure along with the worker node instances, and they count toward the quota of role instances in the subscription.

  • Hyper-V Deployment Options Best Practices

    - by Erv Walter
    In what circumstances would you choose each of the following deployment options: Hyper-V installed as the bare bones Windows Hyper-V Server 2008 R2 Hyper-V role installed on a Windows Server 2008 R2 Server Core installation Hyper-V role installed on a Windows Server 2008 R2 Full Installation For example, I know there are licensing considerations for each option: With Hyper-V on top of a full installation of Enterprise or Data Center edition, you can use Windows Server as a guest OS without needing additional licenses (4 for Enterprise, unlimited for Data Center) With "Windows Hyper-V Server" you have to obtain licenses for each guest OS. But my real question is, are there technical considerations as well? I understand that the Full Installation doesn't perform as well as the other two options, but is there a significant difference between Server Core and "Windows Hyper-V Server"? What are the pros and cons of Hyper-V on Server Core vs "Windows Hyper-V Server" and when would you choose each?
