• Create an iTunes Account without a credit card

  - by Matthew Guay

  iTunes Store offers a large variety of free content, but to download it you have to have an account. Usually you have to enter your credit card information to sign up, but here’s an easy way to get an iTunes account for free downloads without entering any payment info. Although iTunes Store is known for paid downloads of movies, music, and more, it also has a treasure trove of free media.  Some of it, including Podcasts and iTunes U educational content do not require an account to download.  However, any other free content, including free iPhone/iPod Touch apps and free or promotional music, videos, and TV Shows all require an account to download.  If you try to download a free movie or music download, you will be required to enter payment information. Even though your card will not be charged, it will be kept on file so you can be charged if you download a for-pay item.  However, if you only plan to download free items, it may be preferable to not have your account linked to a credit card. The following steps will get you an account without entering your credit card info. Getting Started First, make sure you have iTunes installed.  If you don’t already have it, download and install it (link below) with the default settings. Now open iTunes, and click the iTunes Store link on the left. Click the App Store link on the top of this page. Select a free app to download.  A simple way to do this is to scroll down to the Top Free Apps box on the right side, hover your mouse over the first item, and click on the Free button that appears when you hover over it. A popup will open asking you to sign in with your Apple ID.  Click “Create New Account”. Click Continue to create your account. Check the box to accept the Store Terms and Conditions, and click Continue.   Enter your email address, password, security question, and date of birth, and uncheck the boxes to get email if you don’t want it…then click Continue. Now, you will be asked to provide a payment method.  Notice now that the last option says None!  Click that bullet option… Then enter your billing address.  Simply enter your normal billing address, even though you are not entering a payment method.  Click Continue and your account will be created! If you get the Address Verification screen just verify your county and click Done. An email will be sent to you to verify your account… Click on the link in your email to verify your account, iTunes will launch and you’re prompted to enter in the Apple ID and Password you just created. Your account is successfully created! Now you can easily download any free media from iTunes.  Keep an eye on the Free on iTunes box on the bottom of the iTunes Store page for interesting downloads, or if you have an iPhone or iPod Touch, watch the popular Free downloads on the Apps page. And of course there is always great content on iTunes U to grab free as well. Purchasing for-pay media If you want to purchase an item on the iTunes store later, simply click on the item to download as normal.  Click Buy to proceed with the purchase. iTunes will prompt you that you need to enter payment information to complete the purchase.  Enter your Apple ID email and password, and then add the payment information as prompted.   Remove Payment Information from an iTunes Account If you’ve already entered payment information into your iTunes account, and would like to remove it, click Store in the top iTunes menu, and select View My Account. Enter your Apple ID email and password, and click View Account.   This will open your account information.  Click the Edit Payment Information button.   Now, click the None button to remove your payment information.  Click Done to save the changes. Your account will now prompt you to enter payment information if you try to make a purchase.  You could repeat these steps after making a purchase if you do not want iTunes to keep your payment info on file. Conclusion This is a great way to make an iTunes account without entering your credit card, or to remove your credit card info from your account.  Parents may especially enjoy this tip, as they can have an iTunes account on their kids computer or iPod Touch without worrying about them spending money with it.

• Maps for Business: Generating Valid Signatures

  Maps for Business: Generating Valid Signatures This video shows developers how to generate signed requests to Google Maps for Business Web Services such as the Geocoding API. It also points Maps for Business developers to pertinent documentation like developers.google.com and shows an example of the Maps for Business Welcome Letter. To get a response from the Maps for Business API Web Services, developers need to know: how to find their Maps For Business client ID; how to include that client ID in requests; how to retrieve their Maps for Business digital signing key from the Maps for Business welcome materials; and how to use the key to generate a signature. The video will walk developers through the signature generation steps using Python, and provides pointers to examples in other languages.

• C#/.NET Little Wonders: The Predicate, Comparison, and Converter Generic Delegates

  - by James Michael Hare

  Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. In the last three weeks, we examined the Action family of delegates (and delegates in general), the Func family of delegates, and the EventHandler family of delegates and how they can be used to support generic, reusable algorithms and classes. This week I will be completing my series on the generic delegates in the .NET Framework with a discussion of three more, somewhat less used, generic delegates: Predicate<T>, Comparison<T>, and Converter<TInput, TOutput>. These are older generic delegates that were introduced in .NET 2.0, mostly for use in the Array and List<T> classes.  Though older, it’s good to have an understanding of them and their intended purpose.  In addition, you can feel free to use them yourself, though obviously you can also use the equivalents from the Func family of delegates instead. Predicate<T> – delegate for determining matches The Predicate<T> delegate was a very early delegate developed in the .NET 2.0 Framework to determine if an item was a match for some condition in a List<T> or T[].  The methods that tend to use the Predicate<T> include: Find(), FindAll(), FindLast() Uses the Predicate<T> delegate to finds items, in a list/array of type T, that matches the given predicate. FindIndex(), FindLastIndex() Uses the Predicate<T> delegate to find the index of an item, of in a list/array of type T, that matches the given predicate. The signature of the Predicate<T> delegate (ignoring variance for the moment) is: 1: public delegate bool Predicate<T>(T obj); So, this is a delegate type that supports any method taking an item of type T and returning bool.  In addition, there is a semantic understanding that this predicate is supposed to be examining the item supplied to see if it matches a given criteria. 1: // finds first even number (2) 2: var firstEven = Array.Find(numbers, n => (n % 2) == 0); 3:  4: // finds all odd numbers (1, 3, 5, 7, 9) 5: var allEvens = Array.FindAll(numbers, n => (n % 2) == 1); 6:  7: // find index of first multiple of 5 (4) 8: var firstFiveMultiplePos = Array.FindIndex(numbers, n => (n % 5) == 0); This delegate has typically been succeeded in LINQ by the more general Func family, so that Predicate<T> and Func<T, bool> are logically identical.  Strictly speaking, though, they are different types, so a delegate reference of type Predicate<T> cannot be directly assigned to a delegate reference of type Func<T, bool>, though the same method can be assigned to both. 1: // SUCCESS: the same lambda can be assigned to either 2: Predicate<DateTime> isSameDayPred = dt => dt.Date == DateTime.Today; 3: Func<DateTime, bool> isSameDayFunc = dt => dt.Date == DateTime.Today; 4:  5: // ERROR: once they are assigned to a delegate type, they are strongly 6: // typed and cannot be directly assigned to other delegate types. 7: isSameDayPred = isSameDayFunc; When you assign a method to a delegate, all that is required is that the signature matches.  This is why the same method can be assigned to either delegate type since their signatures are the same.  However, once the method has been assigned to a delegate type, it is now a strongly-typed reference to that delegate type, and it cannot be assigned to a different delegate type (beyond the bounds of variance depending on Framework version, of course). Comparison<T> – delegate for determining order Just as the Predicate<T> generic delegate was birthed to give Array and List<T> the ability to perform type-safe matching, the Comparison<T> was birthed to give them the ability to perform type-safe ordering. The Comparison<T> is used in Array and List<T> for: Sort() A form of the Sort() method that takes a comparison delegate; this is an alternate way to custom sort a list/array from having to define custom IComparer<T> classes. The signature for the Comparison<T> delegate looks like (without variance): 1: public delegate int Comparison<T>(T lhs, T rhs); The goal of this delegate is to compare the left-hand-side to the right-hand-side and return a negative number if the lhs < rhs, zero if they are equal, and a positive number if the lhs > rhs.  Generally speaking, null is considered to be the smallest value of any reference type, so null should always be less than non-null, and two null values should be considered equal. In most sort/ordering methods, you must specify an IComparer<T> if you want to do custom sorting/ordering.  The Array and List<T> types, however, also allow for an alternative Comparison<T> delegate to be used instead, essentially, this lets you perform the custom sort without having to have the custom IComparer<T> class defined. It should be noted, however, that the LINQ OrderBy(), and ThenBy() family of methods do not support the Comparison<T> delegate (though one could easily add their own extension methods to create one, or create an IComparer() factory class that generates one from a Comparison<T>). So, given this delegate, we could use it to perform easy sorts on an Array or List<T> based on custom fields.  Say for example we have a data class called Employee with some basic employee information: 1: public sealed class Employee 2: { 3: public string Name { get; set; } 4: public int Id { get; set; } 5: public double Salary { get; set; } 6: } And say we had a List<Employee> that contained data, such as: 1: var employees = new List<Employee> 2: { 3: new Employee { Name = "John Smith", Id = 2, Salary = 37000.0 }, 4: new Employee { Name = "Jane Doe", Id = 1, Salary = 57000.0 }, 5: new Employee { Name = "John Doe", Id = 5, Salary = 60000.0 }, 6: new Employee { Name = "Jane Smith", Id = 3, Salary = 59000.0 } 7: }; Now, using the Comparison<T> delegate form of Sort() on the List<Employee>, we can sort our list many ways: 1: // sort based on employee ID 2: employees.Sort((lhs, rhs) => Comparer<int>.Default.Compare(lhs.Id, rhs.Id)); 3:  4: // sort based on employee name 5: employees.Sort((lhs, rhs) => string.Compare(lhs.Name, rhs.Name)); 6:  7: // sort based on salary, descending (note switched lhs/rhs order for descending) 8: employees.Sort((lhs, rhs) => Comparer<double>.Default.Compare(rhs.Salary, lhs.Salary)); So again, you could use this older delegate, which has a lot of logical meaning to it’s name, or use a generic delegate such as Func<T, T, int> to implement the same sort of behavior.  All this said, one of the reasons, in my opinion, that Comparison<T> isn’t used too often is that it tends to need complex lambdas, and the LINQ ability to order based on projections is much easier to use, though the Array and List<T> sorts tend to be more efficient if you want to perform in-place ordering. Converter<TInput, TOutput> – delegate to convert elements The Converter<TInput, TOutput> delegate is used by the Array and List<T> delegate to specify how to convert elements from an array/list of one type (TInput) to another type (TOutput).  It is used in an array/list for: ConvertAll() Converts all elements from a List<TInput> / TInput[] to a new List<TOutput> / TOutput[]. The delegate signature for Converter<TInput, TOutput> is very straightforward (ignoring variance): 1: public delegate TOutput Converter<TInput, TOutput>(TInput input); So, this delegate’s job is to taken an input item (of type TInput) and convert it to a return result (of type TOutput).  Again, this is logically equivalent to a newer Func delegate with a signature of Func<TInput, TOutput>.  In fact, the latter is how the LINQ conversion methods are defined. So, we could use the ConvertAll() syntax to convert a List<T> or T[] to different types, such as: 1: // get a list of just employee IDs 2: var empIds = employees.ConvertAll(emp => emp.Id); 3:  4: // get a list of all emp salaries, as int instead of double: 5: var empSalaries = employees.ConvertAll(emp => (int)emp.Salary); Note that the expressions above are logically equivalent to using LINQ’s Select() method, which gives you a lot more power: 1: // get a list of just employee IDs 2: var empIds = employees.Select(emp => emp.Id).ToList(); 3:  4: // get a list of all emp salaries, as int instead of double: 5: var empSalaries = employees.Select(emp => (int)emp.Salary).ToList(); The only difference with using LINQ is that many of the methods (including Select()) are deferred execution, which means that often times they will not perform the conversion for an item until it is requested.  This has both pros and cons in that you gain the benefit of not performing work until it is actually needed, but on the flip side if you want the results now, there is overhead in the behind-the-scenes work that support deferred execution (it’s supported by the yield return / yield break keywords in C# which define iterators that maintain current state information). In general, the new LINQ syntax is preferred, but the older Array and List<T> ConvertAll() methods are still around, as is the Converter<TInput, TOutput> delegate. Sidebar: Variance support update in .NET 4.0 Just like our descriptions of Func and Action, these three early generic delegates also support more variance in assignment as of .NET 4.0.  Their new signatures are: 1: // comparison is contravariant on type being compared 2: public delegate int Comparison<in T>(T lhs, T rhs); 3:  4: // converter is contravariant on input and covariant on output 5: public delegate TOutput Contravariant<in TInput, out TOutput>(TInput input); 6:  7: // predicate is contravariant on input 8: public delegate bool Predicate<in T>(T obj); Thus these delegates can now be assigned to delegates allowing for contravariance (going to a more derived type) or covariance (going to a less derived type) based on whether the parameters are input or output, respectively. Summary Today, we wrapped up our generic delegates discussion by looking at three lesser-used delegates: Predicate<T>, Comparison<T>, and Converter<TInput, TOutput>.  All three of these tend to be replaced by their more generic Func equivalents in LINQ, but that doesn’t mean you shouldn’t understand what they do or can’t use them for your own code, as they do contain semantic meanings in their names that sometimes get lost in the more generic Func name.   Tweet Technorati Tags: C#,CSharp,.NET,Little Wonders,delegates,generics,Predicate,Converter,Comparison

• Long pause in pxe/preseed install

  - by Bo Kersey

  I'm encountering a long pause during unattended (preseeded) install of precise server via pxe. The install eventually works, but appears to just sit there for 20 or 30 minutes after it authenticates the mirror. There is nothing in the logs during this time, even with full debug. Log excerpt: Aug 2 13:29:59 net-retriever: Signature made Fri Aug 2 06:05:28 2013 UTC using DSA key ID 437D05B5 Aug 2 13:29:59 net-retriever: gpgv: Aug 2 13:29:59 net-retriever: Good signature from "Ubuntu Archive Automatic Signing Key <[email protected]>" Aug 2 13:29:59 net-retriever: Aug 2 13:50:10 anna[5072]: DEBUG: resolver (ext2-modules): package doesn't exist (ignored) Aug 2 13:50:10 anna[5072]: DEBUG: resolver (efi-modules): package doesn't exist (ignored) Bug related to this problem that is not being worked. I'm surprised that no one else is complaining about this. Or, is there some other way to do an unattended install that everyone else is using?

• Typical text encoding+BOM, and EOL behavior on mobile devices

  - by Dan W

  Typical things to worry about when dealing with text are the BOM/signature, encoding, and the end of line (EOL) char/chars. I know that Windows often favours \r\n (CR+LF) and Mac/Linux favours \n (LF), but how about mobile devices such as the iPhone and Android? Do typical apps on those platforms favour one or the other? Also, which text encodings are mobiles most likely to use - UTF-8, iso-8859-1, or even Windows 1252 (or other default codepage) or maybe even UTF-16? And if they use UTF-8/16, are they likely to need (or require not having) a BOM/signature? What is the typical behavior here?

• How to send credentials to linkedIn website and get oauth_verifier without signing in again [closed]

  - by akash kumar

  I am facing a problem sending credentials to another website so that I can login the user (automatically, not clicked on sign in here) and get an oauth_verifier value. I want to send the email address and the password through a form (submit button) from my website (e.g. a Liferay portal) to another website (e.g. LinkedIn), so that it automatically returns an oauth_verifier to my website. That means I don't want the user of my website to submit his email and password to LinkedIn again. My goal is to take the email and password of the user in my website and show the user his LinkedIn connection, message, job posting (again, in my website, not LinkedIn). I dont want the user redirected to the LinkedIn website to sign in there and then come back to my website. I have taken a consumer key and a secret key from LinkedIn for my web aplication. I am using the LinkedIn API and getting oauth_verifier for access token but in order to login, I have to take user to LinkedIn to sign in, while I want it to happen in the backend.

• Why prefer a wildcard to a type discriminator in a Java API (Re: Effective Java)

  - by Michael Campbell

  In the generics section of Bloch's Effective Java (which handily is the "free" chapter available to all: http://java.sun.com/docs/books/effective/generics.pdf), he says: If a type parameter appears only once in a method declaration, replace it with a wildcard. (See page 31-33 of that pdf) The signature in question is: public static void swap(List<?> list, int i, int j) vs public static void swap(List<E> list, int i, int j) And then proceeds to use a static private "helper" function with an actual type parameter to perform the work. The helper function signature is EXACTLY that of the second option. Why is the wildcard preferable, since you need to NOT use a wildcard to get the work done anyway? I understand that in this case since he's modifying the List and you can't add to a collection with an unbounded wildcard, so why use it at all?

• One-line command to download Ubuntu ISO?

  - by James Mitch

  I want to download an Ubuntu ISO, preferably over bittorrent, and verify its integrity. Currently, the following steps are required: start web browser, go to ubuntu.com, find download link find gpg signature for the checksums get the gpg key to check gpg signature of the checksums wait until download finished gpg verifiy checksum verification Isn't there a simpler way? Just like apt-get install 12.04-64bit-ubuntu-iso apt-get install 12.04-32bit-server-iso etc.? Of course, apt-get (or whatever it would be called) should download over bittorrent to remove load from the servers. If it doesn't exist, it should probable post that at ubuntu brainstorm? Is there already such a tool? I wanted to ask before posting to brainstorm.

• using egrep to find missing @ in log

  - by jols

  I am using the following command to find log entries that are the result of a log in to the email server: egrep '_login[^ ]' /var/log/exim_mainlog That works fine to find entries that contain content like this: P=esmtpa A=courier_login:[email protected] S=1573 id=f1cd08396,... But what I need to do is to change my grep statement, so that it finds single word logins that do not use the @ sign, like so: P=esmtpa A=courier_login:name S=1573 id=f1cd08396,... Where the log in before was "[email protected]", but in the second log entry, the log in used was only "name". Is this possible using grep or egrep, perhaps in some kind of a compound statement? Thanks much.

• Gmail Rolls Out New Compose Features

  - by Jason Fitzpatrick

  Gmail has several new features that make it even easier to compose email messages including pop-over compositions windows (similar to the Google Chat window), contact profile pictures in the address box, and drag and drop address switching. If you’ve ever had to open two separate windows in order to continually tab back and forth so you could reference one email while composing another, you’ll certainly appreciate the new pop-over compose window that allows you to work within Gmail while keeping a small email composition window open in the corner–as seen in the screenshot above. In addition to that major change, Gmail has also introduced contact photos in the address suggestion window (making it easier than ever to make sure you’re selecting the right recipient) and the ability to drag and drop addresses between the To:, CC:, and BCC: address slots.

• How to Apply a Business Card Template to a Contact and Customize it in Outlook 2013

  - by Lori Kaufman

  If you want to add a business card template to an existing contact in Outlook, you can do so without having to enter all of the information again. We will also show you how to customize the layout and format of the text on the card. Microsoft provides a couple of business card templates you can use. We will use their Blue Sky template as an example. To open the archive file for the template you downloaded, double-click on the .cab file. NOTE: You can also use a tool like 7-Zip to open the archive. A new Extract tab becomes available under Compressed Folder Tools and the files in the archive are listed. Select the .vcf file in the list of files. This automatically activates the Extract tab. Click Extract To and select a location or select Choose location if the desired location is not on the drop-down menu. Select a folder in which you want to save the .vcf file on the Copy Items dialog box and click Copy. NOTE: Use the Make New Folder button to create a new folder for the location, if desired. Double-click on the .vcf file that you copied out of the .cab archive file. By default, .vcf files are associated with Outlook so, when you double-click on a .vcf file, it automatically opens in a Contact window in Outlook. Change the Full Name to match the existing contact to which you want to apply this template. Delete the other contact info from the template. If you want to add any additional information not in the existing contact, enter it. Click Save & Close to save the contact with the new template. The Duplicate Contact Detected dialog box displays. To update the existing contact, select the Update information of selected Contact option. Click Update. NOTE: If you want to create a new contact from this template, select the Add new contact option. With the Contacts folder open (the People link on the Navigation Bar), click Business Card in the Current View section of the Home tab. You may notice that not all the fields from your contact display on the business card you just updated. Double-click on the contact to update the contact and the business card. On the Contact window, right-click on the image of the business card and select Edit Business Card from the popup menu. The Edit Business Card dialog box displays. You can change the design of the card, including changing he background color or image. The Fields box allows you to specify which fields display on the business card and in what order. Notice, in our example, that Company is listed below the Full Name, but no text displays on the business card below the name. That’s because we did not enter any information for Company in the Contact. We have information in Job Title. So, we select Company and click Remove to remove that field. Now, we want to add Job Title. First, select the field below which you want to add the new field. We select Full Name to add the Job Title below that. Then, we click Add and select Organization | Job Title from the popup menu to insert the Job Title. To make the Job Title white like the name, we select Job Title in the list of Fields and click the Font Color button in the Edit section. On the Color dialog box, select the color you want to use for the text in the selected field. Click OK. You can also make text bold, italic, or underlined. We chose to make the Job Title bold and the Full Name bold and italic. We also need to remove the Business Phone because this contact only has a mobile phone number. So, we add a Mobile Phone from the Phone submenu. Then, we need to remove enough blank lines so the Mobile Phone is visible on the card. We also added a website and email address and removed more blank lines so they are visible. You can also move text to the right side of the card or make it centered on the card. We also changed the color of the bottom three lines to blue. Click OK to accept your changes and close the dialog box. Your new business card design displays on the Contact window. Click Save & Close to save the changes you made to the business card for this contact and close the Contact window. The final design of the business card displays in the Business Card view on the People screen. If you have a signature that contains the business card for the contact you just updated, you will also need to update the signature by removing the business card and adding it again using the Business Card button in the Signature editor. You can also add the updated Business Card to a signature without the image or without the vCard (.vcf) file.

• GnuPG v1.4.10 cant read

  - by Nicky Bailuc

  I was thinking of "Getting Involved" with Ubuntu and decided to join the Bug Squad. After a few steps of joining, I got an email with a OpenPGP key licenced at Gnu version 1.4.10 and went on their website. They recommended me a couple of apps that can decode the code, but none of them worked, in fact each of them said that the code is corrupted. I thought that there's something wrong with that email, so I resent the request. As I got another email and tried the code with those programs, the programs said the same thing. How can I decode the code properly? Is there an online way of doing it? Any suggestions?

• How do I mount my External HDD with filesystem type errors?

  - by Snuggie

  I am a relatively new Ubuntu user and I am having some difficulty mounting my external 2TB HDD. When I first installed Linux my external HDD was working just fine, however, it has stopped working and I have a lot of important files on there that I need. Before my HDD would automatically mount and no worries. Now, however, it doesn't automatically mount and when I try to manually mount it I keep running into filesystem type errors that I can't seem to get past. Below are images that depict my step by step process of how I am trying to mount my HDD along with the errors I am receiving. If anybody has any idea what I am doing wrong or how to correct the issue I would greatly appreciate it. Step 1) Ensure the computer recognizes my external HDD. pj@PJ:~$ dmesg ...

• Do database tables need to have IDs?

  - by Arturas M

  Is an ID field is always needed in database tables? In my case I have a user with firstName, lastName and email fields. email is unique and not null, so it could be used as an ID, right? So in that case, could/should I try to remove the ID? Also I want to have another table which extends this one. Let's say its called patient and it has it's own field additionalData and I would like to link the relationship through the email of user I mentioned. So the relationship should be 1 to 1, right? and I wouldn't need the IDs? Somehow MySQL Workbench wants me to use the IDs. What do you guys think. Any suggestions on this topic?

• Copyright of pictures upload to a website?

  - by All

  I want to run a website like stock photos. How can I be sure that the uploader is real copyright holder of the picture? Is it possible to leave the responsibility of this copyright claim to the uploader or at last the webmaster is responsible for the website content? It generally confuses me, as for example, stock photo websites needs form signed by the model for photos showing human face. How they can be sure that the signature actually belongs to the model? How they keep them safe from possible lawsuit in this case (e.g. if selling photos of a models with a fake signature?)

• Is there a good design pattern for this messaging class?

  - by salonMonsters

  Is there a good design pattern for this? I want to create a messaging class. The class will be passed: the type of message (eg. signup, signup confirmation, password reminder etc) the client's id The class needs to then look up the client's messaging preferences in the db (whether they want communication by email, sms or both) Then depending on the client's preference it will format the message for the medium (short version for sms, long form for email) and send it through our mail or sms provider's API. Because the fact that we want to be able to change out email and sms providers if need be I wondered if the Command Pattern would be a good choice.

• Authenticating users for a website

  - by MCB

  I'm working on a website and I want to validate that an individual is an employee at one of a large number of companies (probably using their company's email address, which I don't know before hand). The idea being some users are the general public and others are from these companies. And I need some way to authenticate that the users claiming to be employees are being honest while still having a friendly enough UI. I did an informal survey of people I know and the domains and emails will match in a majority of cases but they might not always match exactly so you might have a company with a website foo.com and an email [email protected] (although foobar.com did redirect back to foo.com). And while I can easily check that I'm not sure what other variations might be out there (maybe fooLA.com and email [email protected], etc.)

• Should EICAR be updated to test the revision of Antivirus system?

  - by makerofthings7

  I'm posting this here since programmers write viruses, and AV software. They also have the best knowledge of heuristics and how AV systems work (cloaking etc). The EICAR test file was used to functionally test an antivirus system. As it stands today almost every AV system will flag EICAR as being a "test" virus. For more information on this historic test virus please click here. Currently the EICAR test file is only good for testing the presence of an AV solution, but it doesn't check for engine file or DAT file up-to-dateness. In other words, why do a functional test of a system that could have definition files that are more than 10 years old. With the increase of zero day threats it doesn't make much sense to functionally test your system using EICAR. That being said, I think EICAR needs to be updated/modified to be effective test that works in conjunction with an AV management solution. This question is about real world testing, without using live viruses... which is the intent of the original EICAR. That being said I'm proposing a new EICAR file format with the appendage of an XML blob that will conditionally cause the Antivirus engine to respond. X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-EXTENDED-ANTIVIRUS-TEST-FILE!$H+H* <?xml version="1.0"?> <engine-valid-from>2010-1-1Z</engine-valid-from> <signature-valid-from>2010-1-1Z</signature-valid-from> <authkey>MyTestKeyHere</authkey> In this sample, the antivirus engine would only alert on the EICAR file if both the signature or engine file is equal to or newer than the valid-from date. Also there is a passcode that will protect the usage of EICAR to the system administrator. If you have a backgound in "Test Driven Design" TDD for software you may get that all I'm doing is applying the principals of TDD to my infrastructure. Based on your experience and contacts how can I make this idea happen?

• Why isn't this simple CRON job working?

  - by JakeRow123

  I am on Ubuntu server and would like to send an email to myself every 10 minutes (as a test). The code for that is in this file: /var/www/cron-test.php To set up the cron I typed: crontab -e and added this line to the bottom of the file using nano editor: ### email me every 10 min. */10 * * * * /var/www/cron-test.php But that script is not running every 10 minutes. I only recieve the email if I load the PHP script directly in my browser. The cron doesn't seem to be executing at all. What am I doing wrong? Also this is my first time setting up a cron so putting the cron script in my www folder is probably not a good idea, should I put it elsewhere? If so where? Also is there a cron error log? Where all failed crons can be seen?
