• Trying to serialize and unserialze a Binary search tree to a file

  - by ClearMist

  I am trying to find a way to use these methods to save and restore a binary search tree that contains names and phone numbers in each node. I am just very lost and how to go about doing this. 'public void save(String fileName) { // TODO : implement this method. // save bst to its original shape. } public void restore(String fileName) { // TODO : implement this method. // restore bst from a file, if file exists. // do nothing, otherwise. File fichier = new File(fileName); if (fichier.exists()) { } }'

• [JAVA]Int to String COmmand

  - by Jack.

  I'm trying to make a piece of code that will yell out anything I input. So the command is 'yell' I want to be able to type 'yell (whatever i want here)' and it will yell it out. I've been able to do it with numbers but I can't do it with a String. So how can I go about that? int x = Integer.valueOf(cmd[1]); n.setNextForceTalk(new ForceTalk("Number: " + x)); That piece of code allows me to type 'yell (number)' and it will come out with whatever number I type. But how can I do it with text.

• Windows Batch script - For /L not working -- simple

  - by XoronioX

  need some quick help. This is a university program, everything is working fine except when I call my :forLoop method to iterate through 100 numbers (1,1,100) starting at 1 going by 1 til 100 and doing the iteration % 5 (i%%5). for some reason I cannot get this to work. appreciate any help or direction. When I echo %%A it is iterating through all the number perfect. When I echo %result% I get a blank "" (nothing inside) :forLoop FOR /L %%A IN (1,1,100) DO ( set /A result=%%A %% 2 echo "%%A" echo "%result%" ) Correct code is :forLoop setlocal ENABLEDELAYEDEXPANSION FOR /L %%A IN (1,1,100) DO ( set /A result=%%A %% 5 echo !result! >> results.txt set /A total=!total!+!result! echo !total! )

• How to resize & move css divisions at same time?

  - by achievelimitless

  I have a division in which i'll be having dynamic numbers of colorful blocks(that too divisions) at various instances. On clicking the box, i want them to expand & cover whole screen. the problem is, while boxes are expanding, they are expanding at there own position & not shifting in the screen.. I used: .elemented1 { width: 100%; height: 80%; -webkit-animation: elemen1 0.3s; border: 0px; } @-webkit-keyframes elemen1 { from { width: 49.6%; height: 39.6%; } to { width: 100%; height: 80%; } } This is working fine but i have to put blocks dynamically. I cant write animations for individual blocks as they will be of different sizes.

• How to take data from textarea and decrypt using javascript?

  - by user1657555

  I need to take data from a textarea on a website and decrypt it using a simple algorithm. The data is in the form of numbers separated by a comma. It also needs to read a space as a space. It looks like 42,54,57, ,57,40,57,44. Heres what I have so far: var my_textarea = $('textarea[name = "words"]').first(); var my_value = $(my_textarea).val(); var my_array = my_value.split(","); for (i=0; i < my_array.length; i++) { var nv = my_array - 124; var acv = nv + 34; var my_result = String.fromCharCode(acv); } prompt("", my_result);

• How to design a database where the main entity table has 25+ columns but a single entity's columns g

  - by thenextwebguy

  The entities to be stored have 25+ properties (table columns). The entities are pretty diverse, meaning that, most of the columns are empty. On average, I'd say, less than 20% (<5) properties have a value in any particular item. So, I have a lot of redundant empty columns for most of the table rows. Almost all of the columns are decimal numbers. Given this scenario, would you suggest serializing the columns instead, or perhaps, create another table named "Property", which would contain all the possible properties and then creating yet another table "EntityProperty" which would map an property to an entity using foreign keys? Or would you leave it as it is?

• Python . How to get rid of '\r' in string?

  - by draconisthe0ry

  I have an excel file that I converted to a text file with a list of numbers. test = 'filelocation.txt' in_file = open(test,'r') for line in in_file: print line 1.026106236 1.660274766 2.686381002 4.346655769 7.033036771 1.137969254 a = [] for line in in_file: a.append(line) print a '1.026106236\r1.660274766\r2.686381002\r4.346655769\r7.033036771\r1.137969254' I wanted to assign each value (in each line) to an individual element in the list. Instead it is creating one element separated by \r . i'm not sure what \r is but why is putting these into the code ? I think I know a way to get rid of the \r from the string but i want to fix the problem from the source

• SQL SERVER – Fix : Error 3623 – An invalid floating point operation occurred

  - by pinaldave

  Going back in time, I always had a problem with mathematics. It was a great subject and I loved it a lot but I only mastered it after practices a lot. I learned that mathematics problems should be addressed systematically and being verbose is not a trick, I learned to solve any problem. Recently one of reader sent me an email with the title “Mathematics problem – please help!” and I was a bit scared. I was good at mathematics but not the best. When I opened the email I was relieved as it was Mathematics problem with SQL Server. My friend received following error while working with SQL Server. Msg 3623, Level 16, State 1, Line 1 An invalid floating point operation occurred. The reasons for the error is simply that invalid usage of the mathematical function is attempted. Let me give you a few examples of the same. SELECT SQRT(-5); SELECT ACOS(-3); SELECT LOG(-9); If you run any of the above functions they will give you an error related to invalid floating point. Honestly there is no workaround except passing the function appropriate values. SQRT of a negative number will give you result in real numbers which is not supported at this point of time as well LOG of a negative number is not possible (because logarithm is the inverse function of an exponential function and the exponential function is NEVER negative). When I send above reply to my friend he did understand that he was passing incorrect value to the function. As mentioned earlier the only way to fix this issue is finding incorrect value and avoid passing it to the function. Every mathematics function is different and there is not a single solution to identify erroneous value passed. If you are facing this error and not able to figure out the solution. Post a comment and I will do my best to figure out the solution.

• VS 2010 JavaScript editor – matching braces highlighting – is it so difficult to implement?

  - by AGS777

  I do not know. Just curious. But first things first. As a web developer I spend about 80% of my work-time editing JavaScript code. And since my server-side platform is .NET then it would be very convenient to have decent JavaScript text editor within Visual Studio IDE. So, Visual Studio 2010 is out. Downloaded and installed. What were my expectations regarding JavaScript editor? Pretty low, actually.  I just wanted to have matching braces highlighted eventually. That’s all. Yes, I know about Ctrl + ] shortcut but it is not event remotely close to convenience. And the result? Alas. Without further ado, just look at some real-world fragment of code from jQuery Templates Proposal experimental plugin as I see it in Notepad++, Notepad2 and Visual Studio 2010 editors respectively: Notepad++ Notepad2 Visual Studio 2010 Look at the highlighted parentheses, regular expression literals, numbers. Do you have a feeling that the last screenshot is not very informative in comparison with the other ones? If yes, then my question is why? Instead I was given an IntelliSense. Sorry, but I do not need it to rot my mind. Especially the one which does not always work properly (try to use it with base2 library for example). With all the expressive power of the language I have to know what I am doing. Instead I still have the same plain old Notepad with some of the JavaScript keywords colorized, plus partially functional/useful IntelliSense. What I do need, is just a little help to make less errors when I type the code – some essential text editor facilities that I really need. Give me that and only then feel free to improve on something else. Maybe I am wrong. Then, sorry. Just cannot believe that I have to wait for another couple of years to get very basic code editor feature.

• Sending mail with Gmail Account using System.Net.Mail in ASP.NET

  - by Jalpesh P. Vadgama

  Any web application is in complete without mail functionality you should have to write send mail functionality. Like if there is shopping cart application for example then when a order created on the shopping cart you need to send an email to administrator of website for Order notification and for customer you need to send an email of receipt of order. So any web application is not complete without sending email. This post is also all about sending email. In post I will explain that how we can send emails from our Gmail Account without purchasing any smtp server etc. There are some limitations for sending email from Gmail Account. Please note following things. Gmail will have fixed number of quota for sending emails per day. So you can not send more then that emails for the day. Your from email address always will be your account email address which you are using for sending email. You can not send an email to unlimited numbers of people. Gmail ant spamming policy will restrict this. Gmail provide both Popup and SMTP settings both should be active in your account where you testing. You can enable that via clicking on setting link in gmail account and go to Forwarding and POP/Imap. So if you are using mail functionality for limited emails then Gmail is Best option. But if you are sending thousand of email daily then it will not be Good Idea. Here is the code for sending mail from Gmail Account. using System.Net.Mail; namespace Experiement { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender,System.EventArgs e) { MailMessage mailMessage = new MailMessage(new MailAddress("[email protected]") ,new MailAddress("[email protected]")); mailMessage.Subject = "Sending mail through gmail account"; mailMessage.IsBodyHtml = true; mailMessage.Body = "<B>Sending mail thorugh gmail from asp.net</B>"; System.Net.NetworkCredential networkCredentials = new System.Net.NetworkCredential("[email protected]", "yourpassword"); SmtpClient smtpClient = new SmtpClient(); smtpClient.EnableSsl = true; smtpClient.UseDefaultCredentials = false; smtpClient.Credentials = networkCredentials; smtpClient.Host = "smtp.gmail.com"; smtpClient.Port = 587; smtpClient.Send(mailMessage); Response.Write("Mail Successfully sent"); } } } That’s run this application and you will get like below in your account.

• Bargain Hunter Round Up – Kicking Off The E-Commerce Holiday Season

  - by Jeri Kelley

  Everyone has a different way to tackle holiday shopping – Black Friday, Small Business Saturday, Cyber Monday, some have it done months in advance, and others wait until the very last minute.   For me, I’m not big into massive crowds so online shopping to the rescue.   Others thrive on the energy of being in the stores on the busiest shopping day of the year.  With last weekend marking the official kick-off to the holiday season, I thought I’d provide a round up of what’s trending:   Online numbers are looking up: According to comScore, for the holiday season-to-date, $16.4 billion has been spent online, marking a 16-percent increase versus the corresponding days last year. Thanksgiving Day – Why wait until Black Friday or Cyber Monday: Online shopping on Thanksgiving Day also increased, totaling $633 million in receipts, a 32 percent increase over Thanksgiving 2011 Black Friday – More than just in-store: Bargain hunters spent $1.042 billion online the day after Thanksgiving, a 26 percent increase of last year's Black Friday, according to new figures released today by market analyst ComScore Cyber Monday Week: Cyber Monday reached $1.465 billion in online spending, up 17 percent versus year ago, representing the heaviest online spending day in history and the second day this season (in addition to Black Friday) to surpass $1 billion in sales                 Cyber Monday is now being dubbed Cyber Week:  “The annual event is increasingly becoming Cyber Week instead of a one-day event as retailers open their arms for Americans who prefer to avoid crowds and compare prices online.” But, Cyber Monday continues its importance, driving a nearly 22% increase in year-over-year (YoY) online sales. Monday sales beat Sunday, the next highest day by a margin of 26.7%. Mobile shopping continues to rise: ChannelAdvisor that said mobile shopping made up 32% of all online spending over the Black Friday weekend Mobile devices were a key part of the online shopping craziness that was November 26th.  Sales from smartphones and tablets doubled this year. I n tablets the growth was 110% and in smartphones - 100% Mobile bar code scans on Black Friday increased 50 percent, according to a report from ScanLife For more on how you can be ready for the holiday season, check out my blog post on commerce strategies for the holidays.

• How to Specify AssemblyKeyFile Attribute in .NET Assembly and Issues

  How to specify strong key file in assembly? Answer: You can specify snk file information using following line [assembly: AssemblyKeyFile(@"c:\Key2.snk")] Where to specify an strong key file (snk file)? Answer: You have two options to specify the AssemblyKeyFile infromation. 1. In class 2. In AssemblyInfo.cs [assembly: AssemblyKeyFile(@"c:\Key2.snk")] 1. In Class you must specify above line before defining namespace of the class and after all the imports or usings Example: See Line 7 in bellow sample class using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Reflection;[assembly: AssemblyKeyFile(@"c:\Key1.snk")]namespace Csharp3Part1{ class Person { public string GetName() { return "Smith"; } }}2. In AssemblyInfo.cs You can aslo specify assembly information in AssemblyInfo.cs Example: See Line 16 in bellow sample AssemblyInfo.csusing System.Reflection;using System.Runtime.CompilerServices;using System.Runtime.InteropServices;// General Information about an assembly is controlled through the following// set of attributes. Change these attribute values to modify the information// associated with an assembly.[assembly: AssemblyTitle("Csharp3Part1")][assembly: AssemblyDescription("")][assembly: AssemblyConfiguration("")][assembly: AssemblyCompany("Deloitte")][assembly: AssemblyProduct("Csharp3Part1")][assembly: AssemblyCopyright("Copyright © Deloitte 2009")][assembly: AssemblyTrademark("")][assembly: AssemblyCulture("")][assembly: AssemblyKeyFile(@"c:\Key1.snk")]// Setting ComVisible to false makes the types in this assembly not visible// to COM components. If you need to access a type in this assembly from// COM, set the ComVisible attribute to true on that type.[assembly: ComVisible(false)]// The following GUID is for the ID of the typelib if this project is exposed to COM[assembly: Guid("4350396f-1a5c-4598-a79f-2e1f219654f3")]// Version information for an assembly consists of the following four values://// Major Version// Minor Version// Build Number// Revision//// You can specify all the values or you can default the Build and Revision Numbers// by using the '*' as shown below:// [assembly: AssemblyVersion("1.0.*")][assembly: AssemblyVersion("1.0.0.0")][assembly: AssemblyFileVersion("1.0.0.0")]Issues:You should not sepcify this in following ways. 1. In multiple classes. 2. In both class and AssemblyInfo.cs If you did wrong in either one of the above ways, Visual Studio or C#/VB.NET compilers shows following Error Duplicate 'AssemblyKeyFile' attribute and warning Use command line option '/keyfile' or appropriate project settings instead of 'AssemblyKeyFile' To avoid this, Please specity your keyfile information only one time either only in one class or in AssemblyInfo.cs file. It is suggested to specify this at AssemblyInfo.cs file You might also encounter the errors like Error: type or namespace name 'AssemblyKeyFileAttribute' and 'AssemblyKeyFile' could not be found.

• Imperative Programming v/s Declarative Programming v/s Functional Programming

  - by kaleidoscope

  Imperative Programming :: Imperative programming is a programming paradigm that describes computation in terms of statements that change a program state. In much the same way as the imperative mood in natural languages expresses commands to take action, imperative programs define sequences of commands for the computer to perform. The focus is on what steps the computer should take rather than what the computer will do (ex. C, C++, Java). Declarative Programming :: Declarative programming is a programming paradigm that expresses the logic of a computation without describing its control flow. It attempts to minimize or eliminate side effects by describing what the program should accomplish, rather than describing how to go about accomplishing it. The focus is on what the computer should do rather than how it should do it (ex. SQL). A  C# example of declarative v/s. imperative programming is LINQ. With imperative programming, you tell the compiler what you want to happen, step by step. For example, let's start with this collection, and choose the odd numbers: List<int> collection = new List<int> { 1, 2, 3, 4, 5 }; With imperative programming, we'd step through this, and decide what we want: List<int> results = new List<int>(); foreach(var num in collection) {     if (num % 2 != 0)           results.Add(num); } Here’s what we are doing: *Create a result collection *Step through each number in the collection *Check the number, if it's odd, add it to the results With declarative programming, on the other hand, we write the code that describes what you want, but not necessarily how to get it var results = collection.Where( num => num % 2 != 0); Here, we're saying "Give us everything where it's odd", not "Step through the collection. Check this item, if it's odd, add it to a result collection." Functional Programming :: Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It emphasizes the application of functions.Functional programming has its roots in the lambda calculus. It is a subset of declarative languages that has heavy focus on recursion. Functional programming can be a mind-bender, which is one reason why Lisp, Scheme, and Haskell have never really surpassed C, C++, Java and COBOL in commercial popularity. But there are benefits to the functional way. For one, if you can get the logic correct, functional programming requires orders of magnitude less code than imperative programming. That means fewer points of failure, less code to test, and a more productive (and, many would say, happier) programming life. As systems get bigger, this has become more and more important.

• JMX Based Monitoring - Part Two - JVM Monitoring

  - by Anthony Shorten

  This the second article in the series focussing on the JMX based monitoring capabilities possible with the Oracle Utilities Application Framework. In all versions of the Oracle utilities Application Framework, it is possible to use the basic JMX based monitoring available with the Java Virtual Machine to provide basic statistics ablut the JVM. In Java 5 and above, the JVM automatically allowed local monitoring of the JVM statistics from an approporiate console. When I say local I mean the monitoring tool must be executed from the same machine (and in some cases the same user that is running the JVM) to connect to the JVM directly. If you are using jconsole, for example, then you must have access to a GUI (X-Windows or Windows) to display the jconsole output. This is the easist way of monitoring without doing too much configration but is not always practical. Java offers a remote monitorig capability to allow yo to connect to a remotely executing JVM from a console (like jconsole). To use this facility additional JVM options must be added to the command line that started the JVM. Details of the additional options for the version of the Java you are running is located at the JMX information site. Typically to remotely connect to a running JVM that JVM must be configured with the following categories of options: JMX Port - The JVM must allow connections on a listening port specified on the command line Connection security - The connection to the JVM can be secured. This is recommended as JMX is not just a monitoring protocol it is a managemet protocol. It is possible to change values in a running JVM using JMX and there are NO "Are you sure?" safeguards. For a Oracle Utilities Application Framework based application there are a few guidelines when configuring and using this JMX based remote monitoring of the JVM's: Online JVM - The JVM used to run the online system is embedded within the J2EE Web Application Server. To enable JMX monitoring on this JVM you can either change the startup script that starts the Web Application Server or check whether your J2EE Web Application natively supports JVM statistics collection. Child JVM's (COBOL only) - The Child JVM's should not be monitored using this method as they are recycled regularly by the configuration and therefore statistics collected are of little value. Batch Threadpoools - Batch already has a JMX interface (which will be covered in another article). Additional monitoring can be enabled but the base supported monitoring is sufficient for most needs. If you are an Oracle Utilities Application Framework site, then you can specify the additional options for JMX Java monitoring on the OPTS paramaters supported for each component of the architecture. Just ensure the port numbers used are unique for each JVM running on any machine.

• Measuring Social Media Efforts

  - by David Dorf

  So you're on the bandwagon and you've created a Facebook page, you're tweeting everyday, and maybe you've even got a YouTube channel. Now what? After you put any program in place, you need to measure, set new goals, then execute and this is no different. But how does one measure social media efforts? First, I guess we need some goals. Typical ones might be to acquire customers, engage them, then convert them. So that translates to: Increase Facebook fans and Twitter followers Increase comments/posting and retweets Increase redemption of offers via Facebook and Twitter Counting fans and followers is easy, and tracking the redemption of coupons isn't that hard either, but measuring engagement is a tough one. How do you know whether your fans are reading your posts, and whether your posts have any meaning to them? For Facebook, the fan page administrator has access to analytics called Facebook Insights. There you can check weekly metrics such as total fans, new fans, lost fans, demographics of fans, number of postings, numbers clicks, etc. Not nearly as comprehensive as Google Analytics, but well on its way. For Twitter, getting information is a little tougher. Again, its easy to track followers and you can use tools like TweetMeme to encourage and track retweets. An interesting website called WeFollow tries to measure influence for certain topics. For example, the top three influencers for the topic "retail" are retailweek, retailwire, and retailerdaily. Other notables are #10 BestBuy, #11 GapOfficial, #12 JeffPR, and #17 OracleRetail. I assume influence is calculated based on number of followers, number of retweets, frequency of tweets, and perhaps depth of dialogs. If you want to get serious about monitoring and measuring social marketing efforts, you'd be wise to invest in a strong tool. Several are listed on this wiki, including big ones like Radian6, Nielsen, Omniture, and Buzzient. Buzzient might be particularly interesting because its integrated with Oracle CRM OnDemand -- see the demo. As always, I'm interested in hearing how others approach goal setting and monitoring of social media efforts, so feel free to post comments.

• Facebook Sponsored Results: Is It Getting Results?

  - by Mike Stiles

  Social marketers who like to focus on the paid aspect of the paid/earned hybrid Facebook represents may want to keep themselves aware of how the network’s new Sponsored Results ad product is performing. The ads, which appear when a user conducts a search from the Facebook search bar, have only been around a week or so. But the first statistics coming out of them are not bad. Marketer Nanigans says click-through rates on the Sponsored Results have been nearly 23 times better than regular Facebook ads. Some click-through rates have even gone over 3%. Just to give you some perspective, a TechCrunch article points out that’s the same kind of click-through rates that were being enjoyed during the go-go dot com boom of the 90’s. The average across the Internet in its entirety is now somewhere around .3% on a good day, so a 3% number should be enough to raise an eyebrow. Plus the cost-per-click price is turning up 78% lower than regular Facebook ads, so that should raise the other eyebrow. Marketers have gotten pretty used to being able to buy ads against certain keywords. Most any digital property worth its salt that sells ads offers this, and so does Facebook with its Sponsored Results product. But the unique prize Facebook brings to the table is the ability to also buy based on demographic and interest information gleaned from Facebook user profiles. With almost 950 million logging in, this is exactly the kind of leveraging of those users conventional wisdom says is necessary for Facebook to deliver on its amazing potential. So how does the Facebook user fit into this? Notorious for finding out exactly where sponsored marketing messages are appearing and training their eyeballs to avoid those areas, will the Facebook user reject these Sponsored Results? Well, Facebook may have found an area in addition to the News Feed where paid elements can’t be avoided and will be tolerated. If users want to read their News Feed, and they do, they’re going to see sponsored posts. Likewise, if they want to search for friends or Pages, and they do, they’re going to see Sponsored Results. The paid results are clearly marked as such. As long as their organic search results are not tainted or compromised, they will continue using search. But something more is going on. The early click-through rate numbers say not only do users not mind seeing these Sponsored Results, they’re finding them relevant enough to click on. And once they click, they seem to be liking what they find, with a reported 14% higher install rate than Marketplace Ads. It’s early, and obviously the jury is still out. But this is a new social paid marketing opportunity that’s well worth keeping an eye on, and that may wind up hitting the trifecta of being effective for the platform, the consumer, and the marketer.

• SQL SERVER – Automated Type Conversion using Expressor Studio

  - by pinaldave

  Recently I had an interesting situation during my consultation project. Let me share to you how I solved the problem using Expressor Studio. Consider a situation in which you need to read a field, such as customer_identifier, from a text file and pass that field into a database table. In the source file’s metadata structure, customer_identifier is described as a string; however, in the target database table, customer_identifier is described as an integer. Legitimately, all the source values for customer_identifier are valid numbers, such as “109380”. To implement this in an ETL application, you probably would have hard-coded a type conversion function call, such as: output.customer_identifier=stringToInteger(input.customer_identifier) That wasn’t so bad, was it? For this instance, programming this hard-coded type conversion function call was relatively easy. However, hard-coding, whether type conversion code or other business rule code, almost always means that the application containing hard-coded fields, function calls, and values is: a) specific to an instance of use; b) is difficult to adapt to new situations; and c) doesn’t contain many reusable sub-parts. Therefore, in the long run, applications with hard-coded type conversion function calls don’t scale well. In addition, they increase the overall level of effort and degree of difficulty to write and maintain the ETL applications. To get around the trappings of hard-coding type conversion function calls, developers need an access to smarter typing systems. Expressor Studio product offers this feature exactly, by providing developers with a type conversion automation engine based on type abstraction. The theory behind the engine is quite simple. A user specifies abstract data fields in the engine, and then writes applications against the abstractions (whereas in most ETL software, developers develop applications against the physical model). When a Studio-built application is run, Studio’s engine automatically converts the source type to the abstracted data field’s type and converts the abstracted data field’s type to the target type. The engine can do this because it has a couple of built-in rules for type conversions. So, using the example above, a developer could specify customer_identifier as an abstract data field with a type of integer when using Expressor Studio. Upon reading the string value from the text file, Studio’s type conversion engine automatically converts the source field from the type specified in the source’s metadata structure to the abstract field’s type. At the time of writing the data value to the target database, the engine doesn’t have any work to do because the abstract data type and the target data type are just the same. Had they been different, the engine would have automatically provided the conversion. ?Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Database, Pinal Dave, SQL, SQL Authority, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, SQLAuthority News, T SQL, Technology Tagged: SSIS

• Querying Networking Statistics: dlstat(1M)

  - by user12612042

  Oracle Solaris 11 took another big leap forward in networking technologies providing a reliable, secure and scalable infrastructure to meet the growing needs of today's datacenter implementations. Oracle Solaris 11 introduced a new and powerful network stack architecture, also known as Project Crossbow. From Solaris 11 onwards, we introduced a command line tool viz. dlstat(1M) to query network statistics. dlstat (for datalink statistics) is a statistics querying counterpart for dladm(1M) - the datalink administration tool. The tool is very easy to get started. Just type dlstat on a shell prompt on Solaris 11 (or later). For example,: # dlstat LINK IPKTS RBYTES OPKTS OBYTES net0 834.11K 145.91M 575.19K 104.24M net1 7.87K 2.04M 0 0 In this example, the system has two datalinks net0 and net1. The output columns denote input packets/bytes as well as output packets/bytes. The numbers are abbreviated in xxx.xxUnit format. However, one could get the actual counts by simply running dlstat -u R (R for raw): # dlstat -u R LINK IPKTS RBYTES OPKTS OBYTES net0 834271 145931244 575246 104242934 net1 7869 2036958 0 0 In addition, dlstat also supports various subcommands dlstat help The following subcommands are supported: Stats : show-aggr show-ether show-link show-phys show-bridge For more info, run: dlstat help {default|} I will only describe couple of interesting subcommands/options here. For a comprehensive description of all the dlstat subcommands refer dlstat's official manual . For NICs that support multiple rings (e.g. ixgbe), dlstat show-phys -r allows us to query per Rx ring statistics. For example: dlstat show-phys -r net4 LINK TYPE INDEX IPKTS RBYTES net4 rx 0 0 0 net4 rx 1 0 0 net4 rx 2 0 0 net4 rx 3 0 0 net4 rx 4 0 0 net4 rx 5 0 0 net4 rx 6 0 0 net4 rx 7 0 0 In this case, net4 is just a vanity name for an ixgbe datalink. This view is especially useful if one wants to look at the network traffic spread across all the available rings. Furthermore, any of the dlstat commands could be run with -i option to periodically query and display stats. For example, running dlstat show-phys -r net4 -i 5 will emit per Rx ring stats every 5 seconds. This is especially useful while analyzing a live system. Similarly, dlstat show-phys -t could be used to query per Tx ring stats. -r and -t could also be combined as dlstat show-phys -rt to query both Rx as well as Tx stats at the same time. Finally, there is also a quick way to dump ALL the stats. Just run dlstat -A. You probably want to redirect this output to a file because you are going to get a whole load of stats :-).

• My Ubuntu Touch seems to be broken no matter how many different files I try

  - by zeokila

  So I'm planning on testing out Ubuntu Touch, and developing some applications for it so I thought I would flash it to my Nexus 4 that was already unlocked, and running Paranoid Android and the kernel associated. I headed to Ubuntu's website, browsed around and came across this page: Touch/Install - Ubuntu Wiki I followed Step 1 perfectly, word by word. Its seems to me that everything on that part is fine. I skipped Step 2 having already done that for Paranoid Android, and then I follow 3 and 4 word to word also. Using the command phablet-flash -b everything seemed to be fine. So it booted up and all seemed normal, but it wasn't. Here are some major bugs that only seem to happen to me. So I was greeted with a normal lock screen: But one of the first noticable things on the home screen is that I only have 4 tabs, not 5: Some of the applications that are supposed to work do not (I know some are dummies) like here with the calculator, this is what I get: On the homescreen it is a black box, it will crash a couple of seconds later: Another annoying problem is that when I want to close apps, I have from right to left, if I close an app on the left first it will close it, but it will open the app to it's right, weird: Yet another bug, this one is in the pull down drawer, when you just click on it, you can see that not all the icons are there: Pretty much everything else works as it should, but my main problem is that there is no telephony, I'm not sure how it works exactly, but I'm never asked a SIM code (I'm guessing you need that?), I can't compose SMS's and can't dial numbers, it won't let me select the 'Send' or 'Call' button. I've after tried manual installs all over the place with these files: http://cdimage.ubuntu.com/ubuntu-touch-preview/daily-preinstalled/current/saucy-preinstalled-armel+mako.zip (Says 44MB on site - 46.6MB on my laptop) http://cdimage.ubuntu.com/ubuntu-touch-preview/daily-preinstalled/current/saucy-preinstalled-phablet-armhf.zip (Says 366MB on site - 383.2MB on my laptop) There are some weird size differences between what the site told me and what I downloaded, but I've tried re-downloading just to end up with the same file. And it just alway ends up with the same problems. No telephony and those weird bugs. So my question is, how the hell can I get the same version as everyone else, with the ability to send texts and call and open the calculator and more? Also, definitely running saucy: And maybe useful? This is what's in the device info:

Being able to answer this question can provide important insight and value of good project management practices for your organization. According to 400 senior executives who participated in a new survey conducted by the Economist Intelligence Unit and sponsored by Oracle, unrealistic project goals is the main reason for roadblocks to success Other common stumbling blocks are poor alignment between project and organizational goals, inadequate human resources, lack of strong leadership, and unwillingness among team members to point out problems. This survey sample also had a lot to say about the impact of regulatory compliance on the overall portfolio management process. Thirty-nine percent acknowledged that regulations enabled efficient functioning of their businesses. But a similar number said that regulations often require more financial resources than were originally allocated to bring projects in on time. Regulations were seen by 35 percent of the executives as roadblocks to their ability to invest in the organization’s growth and success. These revelations among others are discussed in depth in a new on-demand Webcast titled “Too Good to Fail: Developing Project Management Expertise in Financial Services” now available from Oracle. The Webcast features Brian Gardner, editor of the Economist Intelligence Unit, who presents these findings from this survey along with Guy Barlow, director of industry strategy for Oracle Primavera. Together, they analyze what the numbers mean for project and program managers and the financial services industry. Register today to watch the on-demand Webcast and get a full rundown and analysis of the survey results. Take the Economist Intelligence Unit benchmarking survey and see how your views compare with those of other financial services industry executives in ensuring project success.  Read more in the October Edition of the quarterly Information InDepth EPPM Newsletter

  @oracletechnet: Oracle Technology Network Newsletters Revisited "You may find this hard to believe, but some analysts contend that email newsletters are still among the most preferred methods of "information awareness" by developers today. And in our experience, the numbers back it up: subscriptions to Oracle Technology Network newsletters grow organically by 15% every year, even after you take continual list cleanup into account. " -- Justin Kestelyn (tags: oracle otn newsletters developers architects) Sylvain Duloutre: Directory Services as a Web Service Sylvain Duloutre shares a WSDL file he created to deal with issues involved in XML binding generation. (tags: oracle sun wsdl webservices DSEE netbeans jdeveloper) Nick Wooler: Iron-Clad Cloud: Secure Cloud Computing "One solution to the security problem with cloud services can be overcome using Service Oriented Security. The Oracle approach to using Service Oriented Security allows developers to pull from a centralized, authoritative source of identity services. This allows developers to build security into every application from the inside-out. This is critical to ensuring this is done in a standardized manner and most importantly it allows developers to develop without being security experts." -- Nick Wooler (tags: oracle sun security cloud saas) Andy Mulholland: A week of visits; Cisco, HP, Oracle, SAP and VMware (in alphabetical order!) "I now am considering that we should be thinking about ‘clouds’ in virtual way, by which I mean that a succession of virtual ‘clouds’ will need to exist, each possessing specific characteristics that suit certain types of services. Really it’s no different to what we see with servers today. Adding a hypervisor to a server adds new flexibility, but creating a virtualised environment means much more. What I suspect will happen is that we will start to use vendor specific approaches to building what I will term a physical cloud solution using their technology and approach to supporting a specific objective, but with time we will find these physical clouds will interoperate as a fully virtualised cloud environment." -- Andy Mulholland (tags: entarch enterprisearchitecture cloudcomputing virtualization) @fteter: Highlights From The Bright Lights - Tuesday #c10 Oracle Ace Director Floyd Teter of JPL with one last wrap-up of Collaborate 10.

• Customization: It’s Wanted in Enterprise Tech Platforms Too

  - by Mike Stiles

  Did you know that every customer service person does their job the exact same way in every business organization?  And did you know that every business organization cares about the exact same metrics? I hope not, because both those things couldn’t be farther from the truth. And if there are different needs and approaches in different enterprises, it stands to reason technology platforms must become increasingly customizable. Oracle Social Cloud sees that coming and is doing something about it, at least in terms of social media management. Today we introduce Social Station, a customizable user experience workspace within the Oracle Social Relationship Management (SRM) platform. We think a lot about customer-centricity and customer experience around here, and we know our own customers are ready to start moving forward in being able to set up their work environments in the ways that work best for them. That kind of thing increases productivity, helps deliver on social objectives faster, and generally just makes life more pleasant. A recent IDG Enterprise report says that enterprises currently investing in more consumerized, easy-to-use technologies experience a 56% increase in employee productivity and a 46% increase in customer satisfaction. Imagine that. When you make it easier and more pleasant for employees to help customers, more customers get helped and everyone ends up happier. So what does this Social Station do and what does it mean, exactly? It’s an innovative move to take some pretty high-end tech (take a bow developers) and simplify it, making things more intuitive: Drag and drop lets you easily build out and personalize your social workspace with different modules. The new Custom Analytics module can mix and match over 120 metrics with thousands of customizable reporting options. You can check constantly refreshed updates and keep a real-time eye on the numbers you’re trying to move. One-click sharing and annotation in the Custom Analytics module improves sharing and collaboration across teams, departments and executives. Multi-view layout helps you leverage social insights by letting you monitor conversations by network, stream, metric, graph type, date range, and relative time period. The Enhanced Calendar is a better visual representation of content, posts, networks and views, letting you easily toggle between functions and views. The Oracle Social Station sets us up to always be developing & launching additional social modules for you, covering areas like content curation, influencer engagement, and command center creation. Oracle Social Cloud Group VP Meg Bear says, “Consumers today have high expectations of their technology application capabilities and usability, and those expectations don’t stop when they enter their workplaces.” In other words, internal enterprise technology platforms must reflect the personalization and customization being called for in consumer products and marketing. “One size fits all” is becoming an endangered concept. @mikestiles @oraclesocial

• Inside Red Gate - Divisions

  - by Simon Cooper

  When I joined Red Gate back in 2007, there were around 80 people in the company. Now, around 3 years later, it's grown to more than 200. It's a constant battle against Dunbar's number; the maximum number of people you can keep track of in a social group, to try and maintain that 'small company' feel that attracted myself and so many others to apply in the first place. There are several strategies the company's developed over the years to try and mitigate the effects of Dunbar's number. One of the main ones has been divisionalisation. Divisions The first division, .NET, appeared around the same time that I started in 2007. This combined the development, sales, marketing and management of the .NET tools (then, ANTS Profiler v3) into a separate section of the office. The idea was to increase the cohesion and communication between the different people involved in the entire lifecycle of the tools; from initial product development, through to marketing, then to customer support, who would feed back to the development team. This was such a success that the other development teams were re-worked around this model in 2009. Nowadays there are 4 divisions - SQL Tools, DBA, .NET, and New Business. Along the way there have been various tweaks to the details - the sales teams have been merged into the divisions, marketing and product support have been (mostly) centralised - but the same basic model remains. So, how has this helped? As Red Gate has continued to grow over the years, divisionalisation has turned Red Gate from a monolithic software company into what one person described as a 'federation of small businesses'. Each division is free to structure itself as it sees fit, it's free to decide what to concentrate development work on, organise its own newsletters and webinars, decide its own release schedule. Each division is its own small business. In terms of numbers, the size of each division varies from 20 people (.NET) to 52 (SQL Tools); well below Dunbar's number. From a developer's perspective, this means organisational structure is very flat & wide - there's only 2 layers between myself and the CEOs (not that it matters much; everyone can go and have a chat to Neil or Simon, or anyone else inbetween, whenever they want. Provided you can catch them at their desk!). As Red Gate grows, and expands into new areas, new divisions will be created as needed, old ones merged or disbanded, but the division structure will help to maintain that small-company feel that keeps Red Gate working as it does.
