  • Why does my motherboard go through an endless reboot cycle when 8 GB of memory is attempted vs 6 GB?

    - by nizm0
    I never got an answer in my googling to this about a year ago and have an extra stick of memory I'd like to be able to use. When is inserted the computer starts, and then reboots immediately in an endless reboot cycle. As soon as the 4th stick is removed, the computer works fine. Right now I have 6 GB of my 8 GB installed. Is there a solution that I am missing to enabling this motherboard to actually boot up with all 8 GB (it supports it). Right now it won't even boot up to BIOS with the 4 sticks... only 3?

  • Restricting Input in HTML Textboxes to Numeric Values

    - by Rick Strahl
    Ok, here’s a fairly basic one – how to force a textbox to accept only numeric input. Somebody asked me this today on a support call so I did a few quick lookups online and found the solutions listed rather unsatisfying. The main problem with most of the examples I could dig up was that they only include numeric values, but that provides a rather lame user experience. You need to still allow basic operational keys for a textbox – navigation keys, backspace and delete, tab/shift tab and the Enter key - to work or else the textbox will feel very different than a standard text box. Yes there are plug-ins that allow masked input easily enough but most are fixed width which is difficult to do with plain number input. So I took a few minutes to write a small reusable plug-in that handles this scenario. Imagine you have a couple of textboxes on a form like this: <div class="containercontent"> <div class="label">Enter a number:</div> <input type="text" name="txtNumber1" id="txtNumber1" value="" class="numberinput" /> <div class="label">Enter a number:</div> <input type="text" name="txtNumber2" id="txtNumber2" value="" class="numberinput" /> </div> and you want to restrict input to numbers. Here’s a small .forceNumeric() jQuery plug-in that does what I like to see in this case: [Updated thanks to Elijah Manor for a couple of small tweaks for additional keys to check for] <script type="text/javascript"> $(document).ready(function () { $(".numberinput").forceNumeric(); }); // forceNumeric() plug-in implementation jQuery.fn.forceNumeric = function () { return this.each(function () { $(this).keydown(function (e) { var key = e.which || e.keyCode; if (!e.shiftKey && !e.altKey && !e.ctrlKey && // numbers key >= 48 && key <= 57 || // Numeric keypad key >= 96 && key <= 105 || // comma, period and minus key == 190 || key == 188 || key == 109 || // Backspace and Tab and Enter key == 8 || key == 9 || key == 13 || // Home and End key == 35 || key == 36 || // left and right arrows key == 37 || key == 39 || // Del and Ins key == 46 || key == 45) return true; return false; }); }); } </script> With the plug-in in place in your page or an external .js file you can now simply use a selector to apply it: $(".numberinput").forceNumeric(); The plug-in basically goes through each selected element and hooks up a keydown() event handler. When a key is pressed the handler is fired and the keyCode of the event object is sent. Recall that jQuery normalizes the JavaScript Event object between browsers. The code basically white-lists a few key codes and rejects all others. It returns true to indicate the keypress is to go through or false to eat the keystroke and not process it which effectively removes it. Simple and low tech, and it works without too much change of typical text box behavior.© Rick Strahl, West Wind Technologies, 2005-2011Posted in JavaScript  jQuery  HTML

  • From NaN to Infinity...and Beyond!

    - by Tony Davis
    It is hard to believe that it was once possible to corrupt a SQL Server Database by storing perfectly normal data values into a table; but it is true. In SQL Server 2000 and before, one could inadvertently load invalid data values into certain data types via RPC calls or bulk insert methods rather than DML. In the particular case of the FLOAT data type, this meant that common 'special values' for this type, namely NaN (not-a-number) and +/- infinity, could be quite happily plugged into the database from an application and stored as 'out-of-range' values. This was like a time-bomb. When one then tried to query this data; the values were unsupported and so data pages containing them were flagged as being corrupt. Any query that needed to read a column containing the special value could fail or return unpredictable results. Microsoft even had to issue a hotfix to deal with failures in the automatic recovery process, caused by the presence of these NaN values, which rendered the whole database inaccessible! This problem is history for those of us on more current versions of SQL Server, but its ghost still haunts us. Recently, for example, a developer on Red Gate’s SQL Response team reported a strange problem when attempting to load historical monitoring data into a SQL Server 2005 database via the C# ADO.NET provider. The ratios used in some of their reporting calculations occasionally threw out NaN or infinity values, and the subsequent attempts to load these values resulted in a nasty error. It turns out to be a different manifestation of the same problem. SQL Server 2005 still does not fully support the IEEE 754 standard for floating point numbers, in that the FLOAT data type still cannot handle NaN or infinity values. Instead, they just added validation checks that prevent the 'invalid' values from being loaded in the first place. For people migrating from SQL Server 2000 databases that contained out-of-range FLOAT (or DATETIME etc.) data, to SQL Server 2005, Microsoft have added to the latter's version of the DBCC CHECKDB (or CHECKTABLE) command a DATA_PURITY clause. When enabled, this will seek out the corrupt data, but won’t fix it. You have to do this yourself in what can often be a slow, painful manual process. Our development team, after a quizzical shrug of the shoulders, simply decided to represent NaN and infinity values as NULL, and move on, accepting the minor inconvenience of not being able to tell them apart. However, what of scientific, engineering and other applications that really would like the luxury of being able to both store and access these perfectly-reasonable floating point data values? The sticking point seems to be the stipulation in the IEEE 754 standard that, when NaN is compared to any other value including itself, the answer is "unequal" (i.e. FALSE). This is clearly different from normal number comparisons and has repercussions for such things as indexing operations. Even so, this hardly applies to infinity values, which are single definite values. In fact, there is some encouraging talk in the Connect note on this issue that they might be supported 'in the SQL Server 2008 timeframe'. If didn't happen; SQL 2008 doesn't support NaN or infinity values, though one could be forgiven for thinking otherwise, based on the MSDN documentation for the FLOAT type, which states that "The behavior of float and real follows the IEEE 754 specification on approximate numeric data types". However, the truth is revealed in the XPath documentation, which states that "…float (53) is not exactly IEEE 754. For example, neither NaN (Not-a-Number) nor infinity is used…". Is it really so hard to fix this problem the right way, and properly support in SQL Server the IEEE 754 standard for the floating point data type, NaNs, infinities and all? Oracle seems to have managed it quite nicely with its BINARY_FLOAT and BINARY_DOUBLE types, so it is technically possible. We have an enterprise-class database that is marketed as being part of an 'integrated' Windows platform. Absurdly, we have .NET and XPath libraries that fully support the standard for floating point numbers, and we can't even properly store these values, let alone query them, in the SQL Server database! Cheers, Tony.

  • Apple Magic Mouse scrolling in Ubuntu 9.10

    - by krig
    Just received new Apple Magic Mouse and tried to install it on my computer with Ubuntu 9.10. Mouse was found as Bluetooth mouse, I entered PIN as 0000 (could not find it in user manual, so just googgled it). Now I have 2 buttons working well - left and right, but scrolling does not work. I understand that there is no driver for Magic Mouse for linux, but maybe some enthusiasts already found way to enable scrolling. Without scrolling with only 2 buttons this mouse is just like my first mouse I bought in 1997, Mitsumi as I can remember =)

  • What is this jumper for on my new motherboard?

    - by jasondavis
    I am building a new PC, I just got my motherboard in the mail today. It is a ASRock X58 Extreme 3. I am reading over the manual for it and one of the jumpers says this. There is a 3 pin jumper labeled 1 2 3, with pins 1 and 2 shorted by default it is "+5v" If I manually change it to short jumper pins 2 and 3 instead of 1 and 2 then it will be "+5vSB (standby) for PS/2 or USB wake up events. So I am confused as to exactly what this is for. Can someone explain what it means, why I would want one other the other?

  • What is the difference in RAM speeds?

    - by jasondavis
    I am building a new PC with the intel i7-930 processor. I am wanting to use 12gb of RAM for it (6x2gb sticks). Here is some of the RAM I am looking at G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop 2 of these 3 stick kits. They are rated at 1600 however some of the user reviews on that product say they xcould not get it to run at 1600 and the supplier who makes the RAM made a comment that "I7 doesn't support over DDR3 1066" So I am curious, I do not know much about this, I know the more GB of RAM the better but as for the speeds, I am not sure how much of a difference it makes. So can someone explain to me what the difference in performance may be based on speeds of 1200 vs 1600 ram?

  • Replacement Alternative for Dell FY606 in a Poweredge T105

    - by Mike C
    I have recently upgraded my Poweredge T105 server to use a SAS 6/ir RAID controller. Unfortunately, I did not realize at the time that adding the card would cause the BIOS to complain about a missing hard drive fan. This warning requires that a user press F1 to continue, which is disastrous in a server environment. I have searched all over found that the specific part I need is a Dell FY606 fan. However, I have yet to find a suitable retailer that covers this part. I have contacted Dell and they do not have this part in stock. Are there any alternative models of a fan that I could use in place of an FY606? Seems like a pretty straightforward part, just a fan that connects to a 4-pin power connector on the motherboard.

  • Speed up SQL Server queries with PREFETCH

    - by Akshay Deep Lamba
    Problem The SAN data volume has a throughput capacity of 400MB/sec; however my query is still running slow and it is waiting on I/O (PAGEIOLATCH_SH). Windows Performance Monitor shows data volume speed of 4MB/sec. Where is the problem and how can I find the problem? Solution This is another summary of a great article published by R. Meyyappan at www.sqlworkshops.com.  In my opinion, this is the first article that highlights and explains with working examples how PREFETCH determines the performance of a Nested Loop join.  First of all, I just want to recall that Prefetch is a mechanism with which SQL Server can fire up many I/O requests in parallel for a Nested Loop join. When SQL Server executes a Nested Loop join, it may or may not enable Prefetch accordingly to the number of rows in the outer table. If the number of rows in the outer table is greater than 25 then SQL will enable and use Prefetch to speed up query performance, but it will not if it is less than 25 rows. In this section we are going to see different scenarios where prefetch is automatically enabled or disabled. These examples only use two tables RegionalOrder and Orders.  If you want to create the sample tables and sample data, please visit this site www.sqlworkshops.com. The breakdown of the data in the RegionalOrders table is shown below and the Orders table contains about 6 million rows. In this first example, I am creating a stored procedure against two tables and then execute the stored procedure.  Before running the stored proceudre, I am going to include the actual execution plan. --Example provided by www.sqlworkshops.com --Create procedure that pulls orders based on City --Do not forget to include the actual execution plan CREATE PROC RegionalOrdersProc @City CHAR(20) AS BEGIN DECLARE @OrderID INT, @OrderDetails CHAR(200) SELECT @OrderID = o.OrderID, @OrderDetails = o.OrderDetails       FROM RegionalOrders ao INNER JOIN Orders o ON (o.OrderID = ao.OrderID)       WHERE City = @City END GO SET STATISTICS time ON GO --Example provided by www.sqlworkshops.com --Execute the procedure with parameter SmallCity1 EXEC RegionalOrdersProc 'SmallCity1' GO After running the stored procedure, if we right click on the Clustered Index Scan and click Properties we can see the Estimated Numbers of Rows is 24.    If we right click on Nested Loops and click Properties we do not see Prefetch, because it is disabled. This behavior was expected, because the number of rows containing the value ‘SmallCity1’ in the outer table is less than 25.   Now, if I run the same procedure with parameter ‘BigCity’ will Prefetch be enabled? --Example provided by www.sqlworkshops.com --Execute the procedure with parameter BigCity --We are using cached plan EXEC RegionalOrdersProc 'BigCity' GO As we can see from the below screenshot, prefetch is not enabled and the query takes around 7 seconds to execute. This is because the query used the cached plan from ‘SmallCity1’ that had prefetch disabled. Please note that even if we have 999 rows for ‘BigCity’ the Estimated Numbers of Rows is still 24.   Finally, let’s clear the procedure cache to trigger a new optimization and execute the procedure again. DBCC freeproccache GO EXEC RegionalOrdersProc 'BigCity' GO This time, our procedure runs under a second, Prefetch is enabled and the Estimated Number of Rows is 999.   The RegionalOrdersProc can be optimized by using the below example where we are using an optimizer hint. I have also shown some other hints that could be used as well. --Example provided by www.sqlworkshops.com --You can fix the issue by using any of the following --hints --Create procedure that pulls orders based on City DROP PROC RegionalOrdersProc GO CREATE PROC RegionalOrdersProc @City CHAR(20) AS BEGIN DECLARE @OrderID INT, @OrderDetails CHAR(200) SELECT @OrderID = o.OrderID, @OrderDetails = o.OrderDetails       FROM RegionalOrders ao INNER JOIN Orders o ON (o.OrderID = ao.OrderID)       WHERE City = @City       --Hinting optimizer to use SmallCity2 for estimation       OPTION (optimize FOR (@City = 'SmallCity2'))       --Hinting optimizer to estimate for the currnet parameters       --option (recompile)       --Hinting optimize not to use histogram rather       --density for estimation (average of all 3 cities)       --option (optimize for (@City UNKNOWN))       --option (optimize for UNKNOWN) END GO Conclusion, this tip was mainly aimed at illustrating how Prefetch can speed up query execution and how the different number of rows can trigger this.

  • Trying to use HUAWEI E173 on Ubuntu 12.04

    - by Scott Warren
    I have a HUAWEI E173 usb stick to access the internet. It works normally on windows but I need to use it on my Ubuntu system. I plug it in, and after 25-20 seconds the status light turns green and blinks twice every 3 seconds. I see no changes in my system whatsoever, nothing gets installed, I don't get prompted for my PIN. I tried to create a connection using edit connections. I entered the following parameters: Turkey, Turkcell, My Plan is not listed, Internet. Nothing happens. I tried the lsusb command and got the following: tosh2000@tosh:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 058f:a001 Alcor Micro Corp.

  • Create a Shortcut To Group Policy Editor in Windows 7

    - by Mysticgeek
    If you’re a system administrator and find yourself making changes in Group Policy Editor, you might want to make a shortcut to it. Here we look at creating a shortcut, pinning it to the Taskbar, and adding it to Control Panel. Note: Local Group Policy Editor is not available in Home versions of Windows 7. Typing gpedit.msc into the search box in the Start menu to access Group Policy Editor can get old fast. To create a shortcut, right-click on the desktop and select New \ Shortcut.

  • ASUS P6X58D and 12 GB of RAM

    - by Hunter
    I just assembled my new PC and it screams, BUT it's only recognizing 8 GB of RAM in BIOS and OS rather than the installed 12 GB. In the BIOS the RAM was registering at 1066 MHz so I set it to 1600 MHz. I updated the BIOS to the latest non-beta release. http://www.asus.com/product.aspx?P_ID=wurRaDZ8lo4Ckukj OS: Windows 7 Ultimate 64-bit Motherboard: ASUS P6X58D Premium CPU: Intel Core i7 920 RAM: CORSAIR XMS3 12 GB (6 x 2 GB) 240-Pin DDR3 SDRAM DDR3 1600 HDD: Intel 80 GB SSD SATA II Power supply: Kingwin 1000 W Modular I've installed the Beta BIOS 0808 but no luck!

  • Would firewire networking be better than 100Megabit ethernet?

    - by Josh
    My office network has a fully switched 1000Megabit ethernet network. I have an Apple iMac with a Gigabit NIC and FireWire, and a Compaq laptop with a 100Megabit NIC and a 4-pin FireWire interface. Accessing my office's shared drives using my laptop is (obviously) much loswer using my laptop than my iMac. Would I see a noticeible performance boost if I enabled Internet Connection Sharing on my iMac and shared the private ethernet network from my iMac with my laptop over FireWire? FireWire is 480Mbit/sec, right? So would I see roughly 4x speed improvement with such a setup?

  • Filtering data in LINQ with the help of where clause

    - by vik20000in
     LINQ has bought with itself a super power of querying Objects, Database, XML, SharePoint and nearly any other data structure. The power of LINQ lies in the fact that it is managed code that lets you write SQL type code to fetch data.  Whenever working with data we always need a way to filter out the data based on different condition. In this post we will look at some of the different ways in which we can filter data in LINQ with the help of where clause. Simple Filter for an array. Let’s say we have an array of number and we want to filter out data based on some condition. Below is an example int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 }; var lowNums =                 from num in numbers                 where num < 5                 select num;   Filter based on one of the property in the class. With the help of LINQ we can also filer out data from a list based on value of some property. var soldOutProducts =                 from prod in products                 where prod.UnitsInStock == 0                 select prod; Filter based on Multiple of the property in the class. var expensiveInStockProducts =         from prod in products         where prod.UnitsInStock > 0 && prod.UnitPrice > 3.00M         select prod; Filter based on the index of the Item in the list.In the below example we can see that we are able to filter data based on the index of the item in the list. string[] digits = { "zero", "one", "two", "three", "four", "five", "six"}; var shortDigits = digits.Where((digit, index) => digit.Length < index); There are many other way in which we can filter out data in LINQ. In the above post I have tried and shown few ways using the LINQ. Vikram

  • Why your Netapp is so slow...

    - by Darius Zanganeh
    Have you ever wondered why your Netapp FAS box is slow and doesn't perform well at large block workloads?  In this blog entry I will give you a little bit of information that will probably help you understand why it’s so slow, why you shouldn't use it for applications that read and write in large blocks like 64k, 128k, 256k ++ etc..  Of course since I work for Oracle at this time, I will show you why the ZS3 storage boxes are excellent choices for these types of workloads. Netapp’s Fundamental Problem The fundamental problem you have running these workloads on Netapp is the backend block size of their WAFL file system.  Every application block on a Netapp FAS ends up in a 4k chunk on a disk. Reference:  Netapp TR-3001 Whitepaper Netapp has proven this lacking large block performance fact in at least two different ways. They have NEVER posted an SPC-2 Benchmark yet they have posted SPC-1 and SPECSFS, both recently. In 2011 they purchased Engenio to try and fill this GAP in their portfolio. Block Size Matters So why does block size matter anyways?  Many applications use large block chunks of data especially in the Big Data movement.  Some examples are SAS Business Analytics, Microsoft SQL, Hadoop HDFS is even 64MB! Now let me boil this down for you.  If an application such MS SQL is writing data in a 64k chunk then before Netapp actually writes it on disk it will have to split it into 16 different 4k writes and 16 different disk IOPS.  When the application later goes to read that 64k chunk the Netapp will have to again do 16 different disk IOPS.  In comparison the ZS3 Storage Appliance can write in variable block sizes ranging from 512b to 1MB.  So if you put the same MSSQL database on a ZS3 you can set the specific LUNs for this database to 64k and then when you do an application read/write it requires only a single disk IO.  That is 16x faster!  But, back to the problem with your Netapp, you will VERY quickly run out of disk IO and hit a wall.  Now all arrays will have some fancy pre fetch algorithm and some nice cache and maybe even flash based cache such as a PAM card in your Netapp but with large block workloads you will usually blow through the cache and still need significant disk IO.  Also because these datasets are usually very large and usually not dedupable they are usually not good candidates for an all flash system.  You can do some simple math in excel and very quickly you will see why it matters.  Here are a couple of READ examples using SAS and MSSQL.  Assume these are the READ IOPS the application needs even after all the fancy cache and algorithms.   Here is an example with 128k blocks.  Notice the numbers of drives on the Netapp! Here is an example with 64k blocks You can easily see that the Oracle ZS3 can do dramatically more work with dramatically less drives.  This doesn't even take into account that the ONTAP system will likely run out of CPU way before you get to these drive numbers so you be buying many more controllers.  So with all that said, lets look at the ZS3 and why you should consider it for any workload your running on Netapp today.  ZS3 World Record Price/Performance in the SPC-2 benchmark ZS3-2 is #1 in Price Performance $12.08ZS3-2 is #3 in Overall Performance 16,212 MBPS Note: The number one overall spot in the world is held by an AFA 33,477 MBPS but at a Price Performance of $29.79.  A customer could purchase 2 x ZS3-2 systems in the benchmark with relatively the same performance and walk away with $600,000 in their pocket.

  • Windows 8 Login Password Out of Sync with Windows Live ID

    - by Israel Lopez
    I'm working with a computer that has setup a local account connected under Windows Live ID. The user can login to Live ID (like hotmail) from another computer with the correct credentials. However from the Windows 8 computer using the correct password it indicates. That password is incorrect. Make sure you're using the password for you Mircrosoft Account. You can always reset it at account.live.com/password/reset. Now, I've used NTPASSWD to reset the password, but it seems that since its not a "Local Account" it wont take the new password or blank one. This account also has a "PIN" the user who also has forgotten it. I also tried to enable/password set the local Administrator account but it does not show up for login. Any ideas?

  • Solving Euler Project Problem Number 1 with Microsoft Axum

    - by Jeff Ferguson
    Note: The code below applies to version 0.3 of Microsoft Axum. If you are not using this version of Axum, then your code may differ from that shown here. I have just solved Problem 1 of Project Euler using Microsoft Axum. The problem statement is as follows: If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000. My Axum-based solution is as follows: namespace EulerProjectProblem1{ // http://projecteuler.net/index.php?section=problems&id=1 // // If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. // The sum of these multiples is 23. // Find the sum of all the multiples of 3 or 5 below 1000. channel SumOfMultiples { input int Multiple1; input int Multiple2; input int UpperBound; output int Sum; } agent SumOfMultiplesAgent : channel SumOfMultiples { public SumOfMultiplesAgent() { int Multiple1 = receive(PrimaryChannel::Multiple1); int Multiple2 = receive(PrimaryChannel::Multiple2); int UpperBound = receive(PrimaryChannel::UpperBound); int Sum = 0; for(int Index = 1; Index < UpperBound; Index++) { if((Index % Multiple1 == 0) || (Index % Multiple2 == 0)) Sum += Index; } PrimaryChannel::Sum <-- Sum; } } agent MainAgent : channel Microsoft.Axum.Application { public MainAgent() { var SumOfMultiples = SumOfMultiplesAgent.CreateInNewDomain(); SumOfMultiples::Multiple1 <-- 3; SumOfMultiples::Multiple2 <-- 5; SumOfMultiples::UpperBound <-- 1000; var Sum = receive(SumOfMultiples::Sum); System.Console.WriteLine(Sum); System.Console.ReadLine(); PrimaryChannel::ExitCode <-- 0; } }} Let’s take a look at the various parts of the code. I begin by setting up a channel called SumOfMultiples that accepts three inputs and one output. The first two of the three inputs will represent the two possible multiples, which are three and five in this case. The third input will represent the upper bound of the problem scope, which is 1000 in this case. The lone output of the channel represents the sum of all of the matching multiples: channel SumOfMultiples{ input int Multiple1; input int Multiple2; input int UpperBound; output int Sum;} I then set up an agent that uses the channel. The agent, called SumOfMultiplesAgent, received the three inputs from the channel sent to the agent, stores the results in local variables, and performs the for loop that iterates from 1 to the received upper bound. The agent keeps track of the sum in a local variable and stores the sum in the output portion of the channel: agent SumOfMultiplesAgent : channel SumOfMultiples{ public SumOfMultiplesAgent() { int Multiple1 = receive(PrimaryChannel::Multiple1); int Multiple2 = receive(PrimaryChannel::Multiple2); int UpperBound = receive(PrimaryChannel::UpperBound); int Sum = 0; for(int Index = 1; Index < UpperBound; Index++) { if((Index % Multiple1 == 0) || (Index % Multiple2 == 0)) Sum += Index; } PrimaryChannel::Sum <-- Sum; }} The application’s main agent, therefore, simply creates a new SumOfMultiplesAgent in a new domain, prepares the channel with the inputs that we need, and then receives the Sum from the output portion of the channel: agent MainAgent : channel Microsoft.Axum.Application{ public MainAgent() { var SumOfMultiples = SumOfMultiplesAgent.CreateInNewDomain(); SumOfMultiples::Multiple1 <-- 3; SumOfMultiples::Multiple2 <-- 5; SumOfMultiples::UpperBound <-- 1000; var Sum = receive(SumOfMultiples::Sum); System.Console.WriteLine(Sum); System.Console.ReadLine(); PrimaryChannel::ExitCode <-- 0; }} The result of the calculation (which, by the way, is 233,168) is sent to the console using good ol’ Console.WriteLine().

  • Is your Credit Card Number valid?

    - by Rekha
    The credit card numbers may look like some random unique 16 digits number but those digits inform more than what we think it could be. The first digit of the card is the Major Industry Identifier: 1 and 2 -  Airlines 3  – Travel and Entertainment 4 and 5 -  Banking and Financial 6 – Merchandizing and Banking 7 – Petroleum 8 – Telecommunications 9 – National assignment The first 6 digits represent the Issuer Identification Number: Visa – 4xxxxx Master Card – 51xxxx & 55xxxx The 7th and following digits, excluding the last digit, are the person’s account number which leads to trillion possible combinations if the maximum of 12 digits is used. Many cards only use 9 digits. The final digit is the checksum or check digit. It is used to validate the card number using Luhn algorithm. How To Validate Credit Card Number? Take any credit card number, for example 5588 3201 2345 6789. Step 1: Double every other digit from the right: 5*2      8*2      3*2      0*2      2*2      4*2      6*2      8*2 ————————————————————————- 10        16        6          0          4          8      12        16 Step 2: Add these new digits to undoubled digits. All double digit numbers are added as a sum of their digits, so 16 becomes 1+6 = 7: Undoubled digits:       5          8          2          1          3          5          7          9 Doubled Digits:          10       16         6          0          4          8         12         16 Sum:  5+1+0+8+1+6+2+6+1+0+3+4+5+8+7+1+2+9+1+6 = 76 If the final sum is divisible by 10, then the Credit Card number is valid, if not, the number is invalid or fake!!! Hence the example is a fake number? via mint  cc and image credit This article titled,Is your Credit Card Number valid?, was originally published at Tech Dreams.

  • Sharing my broadband connection over a router

    - by user1004985
    I have a broadband connection which I can connect to my laptop's ethernet port. If I want to use the same connection on another machine I would have to do it via a router (I dont want to use ICS since it requires both machines to be ON). I have a router but its uplink is a 4p4c pin rather that an 8p8c(RJ45) so my broadband cable wont fit into it. The router I have is ZTE ZXDSL 531B. And the broadband connection I am talking about has an antenna on the rooftop from which an ethernet cable (CAT 5) runs to my PC's LAN port. Is there some way of utilising the LAN ports of the router to achieve what I mentioned above. Please Help

  • System shuts down immediately after few sconds

    I have a computer with following specification and was working fine after re-installing the system and refitting sink fan unit. Recently it shuts down automatically after a few seconds. I checked PSU by shorting pin no.s 13 & 14 as well as 14 & 15. It worked well means the PSU fan moves. But I never checked the voltages at different wires. I refitted the heat sink fan by applying thermal paste. but it behaved the same. Again I refitted the Heat Sink Fan, then it worked for 2 minutes and again shut down. Now it shuts down immediately after switching on. Mother board : M26GTM-3VP CPU : AMD athlon PSU : 450 watt Can anyone help?

  • How to Access the Control Panel in Windows 8

    - by Matthew Klein
    With the old Windows Start menu, you could add the Control Panel as a menu or a drop-down list. With Windows 8, you can pin the Control Panel to the Start Screen and taskbar but first you need to know where it is. One of the chief complaints about Windows 8 (or any new version of Microsoft’s operating system) is “where did such-and-such go?” With Windows 8, when MS removed the Start button and Start Menu, it threw a lot of people for a loop. Because the Start Menu was like an old familiar hang out; one of those places that no matter how it changed over the years, it was a fairly reliable place to find stuff whether it was your Documents folder, Devices, Printers, the ability to search your programs and files, and of course, the Control Panel. There are about four ways (so far) to access the Control Panel in Windows 8 Preview Release. HTG Explains: What Is RSS and How Can I Benefit From Using It?

  • Technology vs. Antiquated Methods

    - by AreYouSerious
    So Here I am talking with my Program lead, about technology, and how while my father is the VP of a major company, he still doesn't have a blackberry, or a smart phone. and I think it's funny. Most people would say it's a generational thing. That because he's older, he dosen't accept technology, and that's why. I have trouble swallowing that because this is the same man, who bought a satellite radio for his car, and made sure that the printer for the house was networked so that his and my mom's laptop could print wirelessly from the living room through their wireless network. I think it has to do with more with necessity, and partially with finical responsibility. My father is very financially conciencious. Think about it yourself. you pay for internet at your home. You have internet access at your office. But if you get a smart phone you're going to pay almost the same amount just for that access. A lot of people take it as just another fixed cost... I'm one of those. I don't even think about it, as I check my facebook from the bus, train, or even while sitting in traffic... The convience of having connection everywhere outweigh the financial responsible person screaming at in the back of my mind. However This conversation lead us to another venue of discussion.... what happens when the power dies. if you left your charger at home, or you phone or navi just stops working... are you going to be able to continue on as you did when it was working... let take the navi as an example... if your navi stops working, how many of you know how to use a map, and navigate? can you even find where you are on a map using the cross streets that your stopped at? This is a skill that unfortunatelly is overlooked these days in the child rearing process. Most people don't see the value, while some others can't do it themselves, so how can they teach their offspring? Take another example.... what if your phone gets lost... or stolen, or you drive over it? do you have the numbers in their memorized? are they recorded somewhere? I know that if it weren't for google sync I wouldn't have them backed up... not sufficiently. And what good does that do if you're in timbuckto and your phone dies, think you can get on the internet to look up those numbers? Don't get me wrong. I'm the first to see the value in technology, and am willing to pay the price to not have to wait for prices to come down. I will pay extra to have that newest thing right now. but let me tell you what.... I know that should I ever procreate it will be a requirement for my offspring (children) to learn how to do something manually before I'll let them use technology. Food for thought?? Let everyone else know what you think.... just sayin'

  • Are there too many qualified software development engineers chasing too few jobs?

    - by T Gregory
    I am trying to write this question in a non-argumentative way, but it is quite emotionally charged for some, so please bear with me. In the U.S., we hear constantly from CEOs that they cannot find enough qualified software engineers. In fact, it is the position of the U.S. government that demand for software engineering talent outpaces supply. This position can be clearly seen in the granting of tens of thousands of H1B visas, but also in the following excerpt from the official 2010-11 Bureau of Labor Statistics Occupational Outlook Handbook: Employment of computer software engineers is expected to increase by 32 percent from 2008-2018, which is much faster than the average for all occupations. In addition, this occupation will see a large number of new jobs, with more than 295,000 created between 2008 and 2018. Demand for computer software engineers will increase as computer networking continues to grow. For example, expanding Internet technologies have spurred demand for computer software engineers who can develop Internet, intranet, and World Wide Web applications. Likewise, electronic data-processing systems in business, telecommunications, healthcare, government, and other settings continue to become more sophisticated and complex. Implementing, safeguarding, and updating computer systems and resolving problems will fuel the demand for growing numbers of systems software engineers. New growth areas will also continue to arise from rapidly evolving technologies. The increasing uses of the Internet, the proliferation of Web sites, and mobile technology such as the wireless Internet have created a demand for a wide variety of new products. As more software is offered over the Internet, and as businesses demand customized software to meet their specific needs, applications and systems software engineers will be needed in greater numbers. In addition, the growing use of handheld computers will create demand for new mobile applications and software systems. As these devices become a larger part of the business environment, it will be necessary to integrate current computer systems with this new, more mobile technology. However, from the the employee side of the equation, we often hear the opposite. Many of the stories of SDEs with graduate degrees and decades of experience on the unemployment line, or the big tech interview war stories, are anecdotal, for sure. But, there is one piece of data that is neither anecdotal nor transitory, and that is the aggregate decisions of millions of undergraduates of what degree to pursue. Here, a different picture emerges from the data, and that picture is not good for the software profession. According the most recent Taulbee Survey from Computer Research Association, undergrad degree production in CS and CE has fallen nearly 60% since 2004. (Undergrad enrollments have ticked up in the past two years, but only modestly). Here we see that a basic disconnect between what corporate CEOs and the US government are saying and what potential employees really think about job prospects in software engineering. So my questions are these. Who are we to believe? Is there an acute talent shortage, or is there a long-term structural oversupply in the SDE labor market? Can anyone provide reliable data on long-term unemployment among SDEs? How many are leaving the profession due to lack of work? Real data is most helpful. Thanks.

  • Wifi range issues and intermittent dropouts, Thinkpad Edge

    - by jimbo
    If I am more than a couple of metres from my access point (and I'm seeing this across various APs) with my newish Thinkpad Edge 15, running 10.10, the wifi performance becomes ... flaky. When this is happening, I see the following in dmesg, although I'm not sure if it's related: [ 2497.011099] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2502.012711] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2507.009254] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2512.008367] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2517.007467] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2522.006558] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2527.008157] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2532.007251] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2537.003838] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2542.005427] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2547.004496] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2552.003611] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded lspci -vvv has the following to say about my wireless adapter: 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 Subsystem: Intel Corporation Centrino Wireless-N 1000 BGN Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 49 Region 0: Memory at f0500000 (64-bit, non-prefetchable) [size=8K] Capabilities: <access denied> Kernel driver in use: iwlagn Kernel modules: iwlagn If I get within a couple of metres of the access point, I still see that output in dmesg, but the connection stabilises.

As ever let me know if there's other information that would help! Edit: I am using this machine in exactly the same locations I used my previous Thinkpad (T61) running various older versions of Ubuntu, so I definitely feel there is something wrong, rather me having unreasonable expectations of range!
