• How do I (tactfully) tell my project manager or lead developer that the project's codebase needs serious work?

  - by Adam Maras

  I just joined a (relatively) small development team that's been working on a project for several months, if not a year. As with most developer joining a project, I spent my first couple of days reviewing the project's codebase. The project (a medium- to large-sized ASP.NET WebForms internal line of business application) is, for lack of a more descriptive term, a disaster. There are three immediately noticeable problems with the coding standards: The standard is very loose. It describes more of what not to do (don't use Hungarian notation, etc..) than what to do. The standard isn't always followed. There are inconsistencies with the code formatting everywhere. The standard doesn't follow Microsoft's style guidelines. In my opinion, there's no value in deviating from the guidelines that were set forth by the developer of the framework and the largest contributor to the language specification. As for point 3, perhaps it bothers me more because I've taken the time to get my MCPD with a focus on web applications (specifically, ASP.NET). I'm also the only Microsoft Certified Professional on the team. Because of what I learned in all of my schooling, self-teaching, and on-the-job learning (including my preparation for the certification exams) I've also spotted several instances in the project's code where things are simply not done in the best way. I've only been on this team for a week, but I see so many issues with their codebase that I imagine I'll be spending more time fighting with what's already written to do things in "their way" than I would if I were working on a project that, for example, followed more widely accepted coding standards, architecture patterns, and best practices. This brings me to my question: Should I (and if so, how do I) propose to my project manager and team lead that the project needs to be majorly renovated? I don't want to walk into their office, waving my MCTS and MCPD certificates around, saying that their project's codebase is crap. But I also don't want to have to stay silent and have to write kludgey code atop their kludgey code, because I actually want to write quality software and I want the end product to be stable and easily maintainable.

• USB question (how durable is it, how should I workaround this)

  - by Shiki

  The plot is quite simple. Got a Razer mouse. If I plug it in, it works. After a shutdown/hibernation, I have to replug it entirely at the back of the PC. (It works in my laptop even after severel shutdown, etc, so yes I guess it's my motherboard.. but it still got 2 years of warranty and it comes with quad SLI, its not an old motherboard at all. (MSI P7N SLI FI (bought it after a hungarian guy's recommendation)). So. I only could come up with one "solution". Get 3 USB cable (you know, USB-USB). If its possible the shortest ones (don't know if the responsibility/anything will worsen), AND replug only the middle+closest to the USB port junction, since those are replaceable. What do you think? Any other idea? (BIOS is updated, mouse driver ... doesn't really matter, the mouse won't even blink a bit after this happens. It lights up and goes totally dead.)

• Noisily rendered text in Firefox

  - by Notinlist

  It came to me in a week or so that certain pages (Facebook, StrackOverflow, some news sites) have text rendering errors in Firefox. As a workaround if I refresh the page, or simply select and deselect the buggy text, the unpleasant effect disappears. I don't have this effect in Internet Explorer or in any of my desktop applications. Windows 7 Pro 64bit (fresh) Firefox 19.0.2 (fresh) Ati Radeon HD 4600 Series (fresh drivers) Thanks for the help in advance! Update 1/2 I have only three addons: Forecastfox, Hungarian spell checking dictionary and Quick locale switcher. The latter two are installed after the effect appeared. I disabled the first individually and did not helped. But if I start my firefox with disabled addons I cannot reproduce the error. As far as I know this mode does not mean disabled plugins, which I do have (Adobe Acrobat, Citrix ICA Client, Google Earth plugin, Google update, Java Deployment Toolkit 6, MS Office 2010, MS Windows Media Player Firefox, Shockwave Flash, Silverlight, VLC Web). Update 2/2 If I disable all plugins and extensions I still have the problem. If I start Firefox with disabled addons then I cannot reproduce the problem.

• `# probe: true` in /etc/rc.d/init.d/* files on a RedHat system

  - by Chen Levy

  Some files (e.g. nfs, nfslock, bind) in my /etc/rc.d/init.d/ directory have in their comment header a line such as: # probe: true I found that those particular scripts has the probe verb i.e.: service nfs probe But this is due to the fact that the mentioned scripts has code that deals with the probe verb. I find no mention of the # probe: true notation in chkconfig man page, nor in any related man pages. Googleing for it also didn't help. Is there a real significance for that line, or is it pure documentation?

• Metro: Namespaces and Modules

  - by Stephen.Walther

  The goal of this blog entry is to describe how you can use the Windows JavaScript (WinJS) library to create namespaces. In particular, you learn how to use the WinJS.Namespace.define() and WinJS.Namespace.defineWithParent() methods. You also learn how to hide private methods by using the module pattern. Why Do We Need Namespaces? Before we do anything else, we should start by answering the question: Why do we need namespaces? What function do they serve? Do they just add needless complexity to our Metro applications? After all, plenty of JavaScript libraries do just fine without introducing support for namespaces. For example, jQuery has no support for namespaces and jQuery is the most popular JavaScript library in the universe. If jQuery can do without namespaces, why do we need to worry about namespaces at all? Namespaces perform two functions in a programming language. First, namespaces prevent naming collisions. In other words, namespaces enable you to create more than one object with the same name without conflict. For example, imagine that two companies – company A and company B – both want to make a JavaScript shopping cart control and both companies want to name the control ShoppingCart. By creating a CompanyA namespace and CompanyB namespace, both companies can create a ShoppingCart control: a CompanyA.ShoppingCart and a CompanyB.ShoppingCart control. The second function of a namespace is organization. Namespaces are used to group related functionality even when the functionality is defined in different physical files. For example, I know that all of the methods in the WinJS library related to working with classes can be found in the WinJS.Class namespace. Namespaces make it easier to understand the functionality available in a library. If you are building a simple JavaScript application then you won’t have much reason to care about namespaces. If you need to use multiple libraries written by different people then namespaces become very important. Using WinJS.Namespace.define() In the WinJS library, the most basic method of creating a namespace is to use the WinJS.Namespace.define() method. This method enables you to declare a namespace (of arbitrary depth). The WinJS.Namespace.define() method has the following parameters: · name – A string representing the name of the new namespace. You can add nested namespace by using dot notation · members – An optional collection of objects to add to the new namespace For example, the following code sample declares two new namespaces named CompanyA and CompanyB.Controls. Both namespaces contain a ShoppingCart object which has a checkout() method: // Create CompanyA namespace with ShoppingCart WinJS.Namespace.define("CompanyA"); CompanyA.ShoppingCart = { checkout: function (){ return "Checking out from A"; } }; // Create CompanyB.Controls namespace with ShoppingCart WinJS.Namespace.define( "CompanyB.Controls", { ShoppingCart: { checkout: function(){ return "Checking out from B"; } } } ); // Call CompanyA ShoppingCart checkout method console.log(CompanyA.ShoppingCart.checkout()); // Writes "Checking out from A" // Call CompanyB.Controls checkout method console.log(CompanyB.Controls.ShoppingCart.checkout()); // Writes "Checking out from B" In the code above, the CompanyA namespace is created by calling WinJS.Namespace.define(“CompanyA”). Next, the ShoppingCart is added to this namespace. The namespace is defined and an object is added to the namespace in separate lines of code. A different approach is taken in the case of the CompanyB.Controls namespace. The namespace is created and the ShoppingCart object is added to the namespace with the following single line of code: WinJS.Namespace.define( "CompanyB.Controls", { ShoppingCart: { checkout: function(){ return "Checking out from B"; } } } ); Notice that CompanyB.Controls is a nested namespace. The top level namespace CompanyB contains the namespace Controls. You can declare a nested namespace using dot notation and the WinJS library handles the details of creating one namespace within the other. After the namespaces have been defined, you can use either of the two shopping cart controls. You call CompanyA.ShoppingCart.checkout() or you can call CompanyB.Controls.ShoppingCart.checkout(). Using WinJS.Namespace.defineWithParent() The WinJS.Namespace.defineWithParent() method is similar to the WinJS.Namespace.define() method. Both methods enable you to define a new namespace. The difference is that the defineWithParent() method enables you to add a new namespace to an existing namespace. The WinJS.Namespace.defineWithParent() method has the following parameters: · parentNamespace – An object which represents a parent namespace · name – A string representing the new namespace to add to the parent namespace · members – An optional collection of objects to add to the new namespace The following code sample demonstrates how you can create a root namespace named CompanyA and add a Controls child namespace to the CompanyA parent namespace: WinJS.Namespace.define("CompanyA"); WinJS.Namespace.defineWithParent(CompanyA, "Controls", { ShoppingCart: { checkout: function () { return "Checking out"; } } } ); console.log(CompanyA.Controls.ShoppingCart.checkout()); // Writes "Checking out" One significant advantage of using the defineWithParent() method over the define() method is the defineWithParent() method is strongly-typed. In other words, you use an object to represent the base namespace instead of a string. If you misspell the name of the object (CompnyA) then you get a runtime error. Using the Module Pattern When you are building a JavaScript library, you want to be able to create both public and private methods. Some methods, the public methods, are intended to be used by consumers of your JavaScript library. The public methods act as your library’s public API. Other methods, the private methods, are not intended for public consumption. Instead, these methods are internal methods required to get the library to function. You don’t want people calling these internal methods because you might need to change them in the future. JavaScript does not support access modifiers. You can’t mark an object or method as public or private. Anyone gets to call any method and anyone gets to interact with any object. The only mechanism for encapsulating (hiding) methods and objects in JavaScript is to take advantage of functions. In JavaScript, a function determines variable scope. A JavaScript variable either has global scope – it is available everywhere – or it has function scope – it is available only within a function. If you want to hide an object or method then you need to place it within a function. For example, the following code contains a function named doSomething() which contains a nested function named doSomethingElse(): function doSomething() { console.log("doSomething"); function doSomethingElse() { console.log("doSomethingElse"); } } doSomething(); // Writes "doSomething" doSomethingElse(); // Throws ReferenceError You can call doSomethingElse() only within the doSomething() function. The doSomethingElse() function is encapsulated in the doSomething() function. The WinJS library takes advantage of function encapsulation to hide all of its internal methods. All of the WinJS methods are defined within self-executing anonymous functions. Everything is hidden by default. Public methods are exposed by explicitly adding the public methods to namespaces defined in the global scope. Imagine, for example, that I want a small library of utility methods. I want to create a method for calculating sales tax and a method for calculating the expected ship date of a product. The following library encapsulates the implementation of my library in a self-executing anonymous function: (function (global) { // Public method which calculates tax function calculateTax(price) { return calculateFederalTax(price) + calculateStateTax(price); } // Private method for calculating state tax function calculateStateTax(price) { return price * 0.08; } // Private method for calculating federal tax function calculateFederalTax(price) { return price * 0.02; } // Public method which returns the expected ship date function calculateShipDate(currentDate) { currentDate.setDate(currentDate.getDate() + 4); return currentDate; } // Export public methods WinJS.Namespace.define("CompanyA.Utilities", { calculateTax: calculateTax, calculateShipDate: calculateShipDate } ); })(this); // Show expected ship date var shipDate = CompanyA.Utilities.calculateShipDate(new Date()); console.log(shipDate); // Show price + tax var price = 12.33; var tax = CompanyA.Utilities.calculateTax(price); console.log(price + tax); In the code above, the self-executing anonymous function contains four functions: calculateTax(), calculateStateTax(), calculateFederalTax(), and calculateShipDate(). The following statement is used to expose only the calcuateTax() and the calculateShipDate() functions: // Export public methods WinJS.Namespace.define("CompanyA.Utilities", { calculateTax: calculateTax, calculateShipDate: calculateShipDate } ); Because the calculateTax() and calcuateShipDate() functions are added to the CompanyA.Utilities namespace, you can call these two methods outside of the self-executing function. These are the public methods of your library which form the public API. The calculateStateTax() and calculateFederalTax() methods, on the other hand, are forever hidden within the black hole of the self-executing function. These methods are encapsulated and can never be called outside of scope of the self-executing function. These are the internal methods of your library. Summary The goal of this blog entry was to describe why and how you use namespaces with the WinJS library. You learned how to define namespaces using both the WinJS.Namespace.define() and WinJS.Namespace.defineWithParent() methods. We also discussed how to hide private members and expose public members using the module pattern.

• ODI 11g – How to override SQL at runtime?

  - by David Allan

  Following on from the posting some time back entitled ‘ODI 11g – Simple, Powerful, Flexible’ here we push the envelope even further. Rather than just having the SQL we override defined statically in the interface design we will have it configurable via a variable….at runtime. Imagine you have a well defined interface shape that you want to be fulfilled and that shape can be satisfied from a number of different sources that is what this allows - or the ability for one interface to consume data from many different places using variables. The cool thing about ODI’s reference API and this is that it can be fantastically flexible and useful. When I use the variable as the option value, and I execute the top level scenario that uses this temporary interface I get prompted (or can get prompted to be correct) for the value of the variable. Note I am using the <@=odiRef.getObjectName("L","EMP", "SCOTT","D")@> notation for the table reference, since this is done at runtime, then the context will resolve to the correct table name etc. Each time I execute, I could use a different source provider (obviously some dependencies on KMs/technologies here). For example, the following groovy snippet first executes and the query uses SCOTT model with EMP, the next time it is from BOB model and the datastore OTHERS. m=new Properties(); m.put("DEMO.SQLSTR", "select empno, deptno from <@=odiRef.getObjectName("L","EMP", "SCOTT","D")@>"); s=new StartupParams(m); runtimeAgent.startScenario("TOP", null, s, null, "GLOBAL", 5, null, true); m2=new Properties(); m2.put("DEMO.SQLSTR", "select empno, deptno from <@=odiRef.getObjectName("L","OTHERS", "BOB","D")@>"); s2=new StartupParams(m); runtimeAgent.startScenario("TOP", null, s2, null, "GLOBAL", 5, null, true); You’ll need a patch to 11.1.1.6 for this type of capability, thanks to my ole buddy Ron Gonzalez from the Enterprise Management group for help pushing the envelope!

• Nervous about the "real" world

  - by Randy

  I am currently majoring in Computer Science and minoring in mathematics (the minor is embedded in the major). The program has a strong C++ curriculum. We have done some UNIX and assembly language (not fun) and there is C and Java on the way in future classes that I must take. The program I am in did not use the STL, but rather a STL-ish design that was created from the ground up for the program. From what I have read on, the STL and what I have taken are very similar but what I used seemed more user friendly. Some of the programs that I had to write in C++ for assignments include: a password server that utilized hashing of the passwords for security purposes, a router simulator that used a hash table and maps, a maze solver that used depth first search, a tree traveler program that traversed a tree using levelorder, postorder, inorder, selection sort, insertion sort, bit sort, radix sort, merge sort, heap sort, quick sort, topological sort, stacks, queues, priority queues, and my least favorite, red-black trees. All of this was done in three semesters which was just enough time to code them up and turn them in. That being said, if I was told to use a stack to convert an equation to infix notation or something, I would be lost for a few hours. My main concern in writing this is when I graduate and land an interview, what are some of the questions posed to assess my skills? What are some of the most important areas of computer science that are prevalent in the field? I am currently trying to get some ideas of programs I can write in C++ that interest and challenge me to keep learning the language. A sodoku solver came to mind but am lost as to where to start. I apologize for the rant, but I'm just a wee bit nervous about the future. Any tips are appreciated.

• Convert your Hash keys to object properties in Ruby

  - by kerry

  Being a Ruby noob (and having a background in Groovy), I was a little surprised that you can not access hash objects using the dot notation.  I am writing an application that relies heavily on XML and JSON data.  This data will need to be displayed and I would rather use book.author.first_name over book[‘author’][‘first_name’].  A quick search on google yielded this post on the subject. So, taking the DRYOO (Don’t Repeat Yourself Or Others) concept.  I came up with this: 1: class ::Hash 2:  3: # add keys to hash 4: def to_obj 5: self.each do |k,v| 6: if v.kind_of? Hash 7: v.to_obj 8: end 9: k=k.gsub(/\.|\s|-|\/|\'/, '_').downcase.to_sym 10: self.instance_variable_set("@#{k}", v) ## create and initialize an instance variable for this key/value pair 11: self.class.send(:define_method, k, proc{self.instance_variable_get("@#{k}")}) ## create the getter that returns the instance variable 12: self.class.send(:define_method, "#{k}=", proc{|v| self.instance_variable_set("@#{k}", v)}) ## create the setter that sets the instance variable 13: end 14: return self 15: end 16: end This works pretty well.  It converts each of your keys to properties of the Hash.  However, it doesn’t sit very well with me because I probably will not use 90% of the properties most of the time.  Why should I go through the performance overhead of creating instance variables for all of the unused ones? Enter the ‘magic method’ #missing_method: 1: class ::Hash 2: def method_missing(name) 3: return self[name] if key? name 4: self.each { |k,v| return v if k.to_s.to_sym == name } 5: super.method_missing name 6: end 7: end This is a much cleaner method for my purposes.  Quite simply, it checks to see if there is a key with the given symbol, and if not, loop through the keys and attempt to find one. I am a Ruby noob, so if there is something I am overlooking, please let me know.

• Understanding UML composition better

  - by Prog

  The technical difference between Composition and Aggregation in UML (and sometimes in programming too) is that with Composition, the lifetime of the objects composing the composite (e.g. an engine and a steering wheel in a car) is dependent on the composite object. While with Aggregation, the lifetime of the objects making up the composite is independent of the composite. However I'm not sure about something related to composition in UML. Say ClassA is composed of an object of ClassB: class ClassA{ ClassB bInstance; public ClassA(){ bInstance = new ClassB(); } } This is an example of composition, because bInstance is dependent on the lifetime of it's enclosing object. However, regarding UML notation - I'm not sure if I would notate the relationship between ClassA and ClassB with a filled diamond (composition) or a white diamond (aggregation). This is because while the lifetime of some ClassB instances is dependent of ClassA instances - there could be ClassB instances anywhere else in the program - not only within ClassA instances. The question is: if ClassA objects are composed of ClassB objects - but other ClassB objects are free to be used anywhere else in the program: Should the relationship between ClassA and ClassB be notated as aggregation or as composition?

• Copying files within a Workgroup

  - by Andrew La Grange

  I have three boxes operating in a Windows Server workgroup within a closed network. (No Domain / No AD) There are several derivations of the scenario that I'm about to outline, but I'm sure I will be able to retool the solution as and when I need. Essentially the boxes are: 2 x Windows Server 2008 R2 x64 Standard 1 x Windows Server 2000 Standard I need to be able to schedule the copying/and-or/moving of files from various directories and each of the boxes. Each box has a different username and password for the administrator. I have PowerShell 2.0 on the two Win2K8 boxes (obviously). Previously I have used mapped network drives to copy the files, and cmd line batches, but I'd much rather use Powershell if possible (with Shares and/or $ notation). However the Copy-Item cmdlet doesn't seem to be processing the Credential correctly. Perhaps some Powershell gurus out there might be able to help me. Essentially I'd like to schedule a PS run of script to push backup files onto my WIn2k box (old fileserver) periodically.

• Is there a way to add unique items to an array without doing a ton of comparisons?

  - by hydroparadise

  Please bare with me, I want this to be as language agnostic as possible becuase of the languages I am working with (One of which is a language called PowerOn). However, most languanges support for loops and arrays. Say I have the following list in an aray: 0x 0 Foo 1x 1 Bar 2x 0 Widget 3x 1 Whatsit 4x 0 Foo 5x 1 Bar Anything with a 1 should be uniqely added to another array with the following result: 0x 1 Bar 1x 1 Whatsit Keep in mind this is a very elementry example. In reality, I am dealing with 10's of thousands of elements on the old list. Here is what I have so far. Pseudo Code: For each element in oldlist For each element in newlist Compare If values oldlist.element equals newlist.element, break new list loop If reached end of newlist with with nothing equal from oldlist, add value from old list to new list End End Is there a better way of doing this? Algorithmicly, is there any room for improvement? And as a bonus qeustion, what is the O notation for this type of algorithm (if there is one)?

• Would it be a good idea to work on letting people add arrays of numbers in javascript?

  - by OneThreeSeven

  I am a very mathematically oriented programmer, and I happen to be doing a lot of java script these days. I am really disappointed in the math aspects of javascript: the Math object is almost a joke because it has so few methods you can't use ^ for exponentiation the + operator is very limited, you cant add array's of numbers or do scalar multiplication on arrays Now I have written some pretty basic extensions to the Math object and have considered writing a library of advanced Math features, amazingly there doesn't seem to be any sort of standard library already out even for calculus, although there is one for vectors and matricies I was able find. The notation for working with vectors and matricies is really bad when you can't use the + operator on arrays, and you cant do scalar multiplication. For example, here is a hideous expression for subtracting two vectors, A - B: Math.vectorAddition(A,Math.scalarMultiplication(-1,B)); I have been looking for some kind of open-source project to contribute to for awhile, and even though my C++ is a bit rusty I would very much like to get into the code for V8 engine and extend the + operator to work on arrays, to get scalar multiplication to work, and possibly to get the ^ operator to work for exponentiation. These things would greatly enhance the utility of any mathematical javascript framework. I really don't know how to get involved in something like the V8 engine other than download the code and start working on it. Of course I'm afraid that since V8 is chrome specific, that without browser cross-compatibility a fundamental change of this type is likely to be rejected for V8. I was hoping someone could either tell me why this is a bad idea, or else give me some pointers about how to proceed at this point to get some kind of approval to add these features. Thanks!

• Gnuplot with octave produces only entirely black bar diagrams

  - by Lambda Dusk

  My problem is the following: On my system (Linux Mint 14), the normal octave and gnuplot packages only produce completely black bar diagrams: I have tried to change the colours in any way I could imagine, but no avail: bar(xbin, yy, 'barwidth', 1, 'facecolor', 'r', 'edgecolor', 'b'); xlabel('x_i'); ylabel('p_i'); print -deps bars.eps However, when I plot the graph with the command graphics_toolkit fltk; It looks fine - but fltk doesn't either understand umlauts or LaTeX-style formula notation like p_i (necessary for captions and labels). Maybe I haven't configured something correctly. I just installed octave from the repos and thought it would work. Anyone can help?

• looking for a short explanation of fuzzy logic

  - by user613326

  Well i got the idea that basics of fuzzy logic are not that hard to grasp. And i got the feeling that someone might explain it to me in like 30 minutes. Just like i understand neural networks and am able to re-create the famous Xor problem. And go just beyond it and create 3 layer networks of x nodes. I'd like to understand fuzzy till a similar usefully level, in c# language. However the problem is face, I'd like to get concept right however i see many websites who include lots of errors in their basic explaining. Like for example showing pictures and use different numbers as shown in pictures to calculate, as if lots of people just copied stuff without noticing what they write down. While others for me go to deep in their math notation) To me that's very annoying to learn from. For me there is no need to re-invent wheel; Aforge already got a fuzzy logic framework. So what i am looking for are some good examples, good examples like how the neural XOR problem is solved. Is there anyone such a instructional resource out there; do you know a web page, or YouTube where it is shortly explained, what would you recommend me ? Note this article comes close; but it just doesnt nail it for me. After that i downloaded a bunch of free PDF's but most are academic and hard to read for me (i'm not English and dont have a special math degree). (i've been looking around a lot for this, good starter material about it is hard to find).

• What is the correct cipher name for RC4 in Chrome?

  - by qbi

  I want to remove RC4 from Google Chrome and found the commandline option --cipher-suite-blacklist. However I wasn't able to figure out what the correct notation for RC4 is. Whatever I tried so far only brought the message: ERROR:ssl_config_service_manager_pref.cc(55)] Ignoring unrecognized or \ unparsable cipher suite: Even the names listed in ssl_cipher_suite_names.cc don't work. What should I enter to remove RC4 as a cipher for SSL/TLS? I'm working with some different versions of GNU/Linux and sometimes also with Windows. So it would be nice if the command-line argument would work under all OSes. I used the following command: chrome --cipher-suite-blacklist=TLS_RSA_WITH_RC4_128_MD5 --ssl-version-min=tls1.1 chrome --cipher-suite-blacklist=RC4 --ssl-version-min=tls1.1 chrome --cipher-suite-blacklist=0xXYZ,0xUVW --ssl-version-min=tls1.1 # XYZ and UVW are some hexadecimal numbers

• What is this "Change to Display" of math equations and why does it change the equation style in Word 2010?

  - by ysap

  I am writing an equation with the "new" Equation Editor in MS Word 2010 (Insert - Equation). When using one of the "large operators", for example the Sigma, with lower and upper limits, there are two styles for displaying the limits - below and above the Sigma, or to the right as super/subscripts. I am choosing the first style - limits above and below to get the standard notation, but Word formats the equation the other way. Now, the object has a bounding box with a context menu on its right. In this menu, I can select Change to Display and the equation is moved to a new line, w/o adjacent text - but, now the sigma limits appear as requested! Then, selecting Change to Inline reverts to the previous form. So, I want to know if there is away to force the requested form with an "inline" attribute? I know that I can use a MS Equation 3.0 object, but I want to remain with the new, "native" editor.

• 13 IP addresses, how to add them to domain SPF?

  - by Willy

  Hi All, Let say I have these IP addresses on my server: 170.120.210.209 gateway 170.120.210.210 server IP 170.120.210.211 170.120.210.212 170.120.210.213 170.120.210.214 170.120.210.215 170.120.210.216 170.120.210.217 170.120.210.218 170.120.210.219 170.120.210.220 170.120.210.221 170.120.210.222 I am now willing to setup SPF record for my domain but don't want to write each IP one by one. Could you please tell me the short way of this? How can I convert these IP addresses into CIDR notation? Is this correct? 170.120.210.210/28 Thanks for your help.
