• Bison: Optional tokens in a single rule.

  - by Simone Margaritelli

  Hi there .. i'm using GNU Bison 2.4.2 to write a grammar for a new language i'm working on and i have a question. When i specify a rule, let's say : statement : T_CLASS T_IDENT '{' T_CLASS_MEMBERS '}' { // create a node for the statement ... } If i have a variation on the rule, for instance statement : T_CLASS T_IDENT T_EXTENDS T_IDENT_LIST '{' T_CLASS_MEMBERS '}' { // create a node for the statement ... } Where (from flex scanner rules) : "class" return T_CLASS; "extends" return T_EXTENDS; [a-zA-Z\_][a-zA-Z0-9\_]* return T_IDENT; (and T_IDENT_LIST is a rule for comma separated identifiers). Is there any way to specify all of this only in one rule, setting somehow the "T_EXTENDS T_IDENT_LIST" as optional? I've already tried with T_CLASS T_IDENT (T_EXTENDS T_IDENT_LIST)? '{' T_CLASS_MEMBERS '}' { // create a node for the statement ... } But Bison gave me an error. Thanks

• Can I 'unmatch' rule programmatically in treetop?

  - by dimus

  Is it possibe to skip a rule validating it using ruby code in treetop? Say there is something like this: rule short_words [a-z]+ { def method1 text_value end ... } end And I want the words size to be from 2 to 5 letters. Can I exit rule if I find that the length of text_value is not between 2 and 5?

• Server side includes on app engine (<!-- include virtual="header.html" -->)?

  - by Alexandre H. Tremblay

  Hi, I have been trying to figure this out a while. I would like to make my app engine website use basic html and shtml whenever in order to avoid the slow warm-up phase of jsp apps on app engine. This is so that my landing pages load instantly. Basically, I am trying to include an html file into my main html file (index.html - I tried index.shtml). This is the command I try: <!-- include virtual="header.html" --> However it does not work. The server side includes to not seem to get executed in app engine. Do I need to enable these commands somewhere first - or does app engine simply not allow them?

• prolog - infinite rule

  - by Tom

  I have the next rules % Signature: natural_number(N)/1 % Purpose: N is a natural number. natural_number(0). natural_number(s(X)) :- natural_number(X) ackermann(0, N, s(N)). //rule 1 ackermann(s(M),0,Result):- ackermann(M,s(0),Result). //rule 2 ackermann(s(M),s(N),Result):-ackermann(M,Result1,Result),ackermann(s(M),N,Result1). //rule 3 The query is: ackermann (M,N,s(s(0))). Now, as I understood, In the third calculation, we got an infinite search (failture branch). I check it, and I got a finite search (failture branch). I'll explain: In the first, we got a substitue of M=0, N=s(0) (rule 1 - succsess!). In the second, we got a substitue of M=s(0),N=0 (rule 2 - sucsses!). But what now? I try to match M=s(s(0)) N=0, But it got a finite search - failture branch. Why the comipler doesn't write me "fail". Thank you.

• WCF - call same service from client and server side

  - by Steve

  I have a simple WCF service that I call server side from code behind via a service reference. It's used for validation and works and was automatically setup by Visual Studio and is using SOAP I think because the binding is wsHttpBinding. I want to use the same WCF service, but call it client side from jQuery using ajax(). I'm trying to implement it by way of these instructions. But if I make the changes to get the client side call working, I have to add the decoration below which I think will break what works on the server side and also change the system.serviceModel section in web.config. [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json, RequestFormat= WebMessageFormat.Json) ] How do I have a WCF service that can be called both from the server-side and client side (jQuery/ajax)?

• How do I download an attachment from an annotation using client-side JScript?

  - by VVander

  I'm trying to provide a link to the attachment of a note through the client-side JScript. The standard MS-made Notes component does this through the following url: [serverurl]/[appname]/Activities/Attachment/download.aspx?AttachmentType=5&AttachmentId={blahblahblah}&IsNotesTabAttachment=1&CRMWRPCToken=blahblahblah&CRMWRPCTokenTimeStamp=blahblahblah The problem is that I don't know how to get the Token or TokenTimeStamp, so I'm receiving an Access Denied error ("form is no longer available, security precaution, etc"). The only other way I can think of doing this is through the OData endpoint, but that would at best get me a base64 string that I still would have translate into a filestream to give to the browser (all of which seems like it would take forever to implement/figure out). I've found a few other posts that describe the same thing, but no one has answered them: http://social.microsoft.com/Forums/en-US/crmdevelopment/thread/6eb9e0d4-0c0c-4769-ab36-345fbfc9754f/ http://social.microsoft.com/Forums/is/crm/thread/45dabb6e-1c6c-4cb4-85a4-261fa58c04da

• Why exactly is server side HTML rendering faster than client side?

  - by mvbl fst

  I am working on a large web site, and we're moving a lot of functionality to the client side (Require.js, Backbone and Handlebars stack). There are even discussions about possibly moving all rendering to the client side. But reading some articles, especially ones about Twitter moving away from client side rendering, which mention that server side is faster / more reliable, I begin to have questions. I don't understand how rendering fairly simple HTML widgets in JS from JSON and templates is a contemporary browser on a dual core CPU with 4-8 GB RAM is any slower than making dozens of includes in your server side app. Are there any actual real life benchmarking figures regarding this? Also, it seems like parsing HTML templates by server side templating engines can't be any faster than rendering same HTML code from a Handlebars template, especially if this is a precomp JS function?

• SQL SERVER – Server Side Paging in SQL Server 2011 Performance Comparison

  - by pinaldave

  Earlier, I have written about SQL SERVER – Server Side Paging in SQL Server 2011 – A Better Alternative. I got many emails asking for performance analysis of paging. Here is the quick analysis of it. The real challenge of paging is all the unnecessary IO reads from the database. Network traffic was one of the reasons why paging has become a very expensive operation. I have seen many legacy applications where a complete resultset is brought back to the application and paging has been done. As what you have read earlier, SQL Server 2011 offers a better alternative to an age-old solution. This article has been divided into two parts: Test 1: Performance Comparison of the Two Different Pages on SQL Server 2011 Method In this test, we will analyze the performance of the two different pages where one is at the beginning of the table and the other one is at its end. Test 2: Performance Comparison of the Two Different Pages Using CTE (Earlier Solution from SQL Server 2005/2008) and the New Method of SQL Server 2011 We will explore this in the next article. This article will tackle test 1 first. Test 1: Retrieving Page from two different locations of the table. Run the following T-SQL Script and compare the performance. SET STATISTICS IO ON; USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 5 SELECT * FROM Sales.SalesOrderDetail ORDER BY SalesOrderDetailID OFFSET @PageNumber*@RowsPerPage ROWS FETCH NEXT 10 ROWS ONLY GO USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 12100 SELECT * FROM Sales.SalesOrderDetail ORDER BY SalesOrderDetailID OFFSET @PageNumber*@RowsPerPage ROWS FETCH NEXT 10 ROWS ONLY GO You will notice that when we are reading the page from the beginning of the table, the database pages read are much lower than when the page is read from the end of the table. This is very interesting as when the the OFFSET changes, PAGE IO is increased or decreased. In the normal case of the search engine, people usually read it from the first few pages, which means that IO will be increased as we go further in the higher parts of navigation. I am really impressed because using the new method of SQL Server 2011,  PAGE IO will be much lower when the first few pages are searched in the navigation. Test 2: Retrieving Page from two different locations of the table and comparing to earlier versions. In this test, we will compare the queries of the Test 1 with the earlier solution via Common Table Expression (CTE) which we utilized in SQL Server 2005 and SQL Server 2008. Test 2 A : Page early in the table -- Test with pages early in table USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 5 ;WITH CTE_SalesOrderDetail AS ( SELECT *, ROW_NUMBER() OVER( ORDER BY SalesOrderDetailID) AS RowNumber FROM Sales.SalesOrderDetail PC) SELECT * FROM CTE_SalesOrderDetail WHERE RowNumber >= @PageNumber*@RowsPerPage+1 AND RowNumber <= (@PageNumber+1)*@RowsPerPage ORDER BY SalesOrderDetailID GO SET STATISTICS IO ON; USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 5 SELECT * FROM Sales.SalesOrderDetail ORDER BY SalesOrderDetailID OFFSET @PageNumber*@RowsPerPage ROWS FETCH NEXT 10 ROWS ONLY GO Test 2 B : Page later in the table -- Test with pages later in table USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 12100 ;WITH CTE_SalesOrderDetail AS ( SELECT *, ROW_NUMBER() OVER( ORDER BY SalesOrderDetailID) AS RowNumber FROM Sales.SalesOrderDetail PC) SELECT * FROM CTE_SalesOrderDetail WHERE RowNumber >= @PageNumber*@RowsPerPage+1 AND RowNumber <= (@PageNumber+1)*@RowsPerPage ORDER BY SalesOrderDetailID GO SET STATISTICS IO ON; USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 12100 SELECT * FROM Sales.SalesOrderDetail ORDER BY SalesOrderDetailID OFFSET @PageNumber*@RowsPerPage ROWS FETCH NEXT 10 ROWS ONLY GO From the resultset, it is very clear that in the earlier case, the pages read in the solution are always much higher than the new technique introduced in SQL Server 2011 even if we don’t retrieve all the data to the screen. If you carefully look at both the comparisons, the PAGE IO is much lesser in the case of the new technique introduced in SQL Server 2011 when we read the page from the beginning of the table and when we read it from the end. I consider this as a big improvement as paging is one of the most used features for the most part of the application. The solution introduced in SQL Server 2011 is very elegant because it also improves the performance of the query and, at large, the database.

• 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.

• MVC 2 jQuery Client-side Validation

  - by nmarun

  Well, I watched Phil Haack’s show What's New in Microsoft ASP.NET MVC 2 and was impressed about the client-side validation (starts at 17:45) that MVC 2 offers. I tried creating the same, but Phil does not show what .js files need to be included and also I was not able to find the source code for the application that he used. In order to find out the required JavaScript file references, I added all of the files in my application to the page and ran it. Of course it worked, but this is definitely not an optimum solution. By removing one at a time and testing the app, I’ve short-listed the following ones: 1: <script src="../../Scripts/jquery-1.4.1.min.js" type="text/javascript"></script 2: <script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script> 3: <script src="../../Scripts/MicrosoftMvcValidation.js" type="text/javascript"></script> Now, a little about the feature itself. Say, I’m working with a Book application so my model will look something like: 1: public class Book 2: { 3: [HiddenInput(DisplayValue = false)] 4: public int BookId { get; set; } 5:  6: [DisplayName("Book Title")] 7: [Required(ErrorMessage = "Book title is required")] 8: [StringLength(20, ErrorMessage = "Must be under 20 characters")] 9: public string Title { get; set; } 10:  11: [Required(ErrorMessage = "Author is required")] 12: [StringLength(40, ErrorMessage = "Must be under 40 characters")] 13: public string Author { get; set; } 14:  15: public decimal Price { get; set; } 16: 17: [DisplayName("ISBN")] 18: [StringLength(13, ErrorMessage = "Must be 13 characters")] 19: public string Isbn { get; set; } 20: } This ensures that the data passed will be validated upon post. But what would happen if you add the line (along with the above mentioned .js files): 1: <% Html.EnableClientValidation(); %> Now, this acts as ‘on-the-fly’ or ‘real-time’ validation. Now, when the user types 20 characters for the Title, the error shows up right on the 21st character. Beautiful… and you do not have to create the JavaScript function(s) for this. They’re auto-magically created for you. (Doing a ‘View Source’ on the browser page shows you the JavaScript logic that goes on behind the scenes). I bumped into another post that shows how .net 4 allows us to create custom validation attributes: Dynamic Range validation in MVC 2. This will help us attach virtually any business logic to the model itself. Please see the source code I’ve worked with.

• Amazon.com Cutting Off Colorado Affiliates

  - by Joe Mayo

  I received an email from Amazon.com today, essentially cutting off my affiliate status because I'm in Colorado. Colorado recently passed legislation that requires retailers to either collect sales tax for on-line transactions or engage in an onerous process that makes you wish you had collected sales tax.  After I Tweeted this, Mike Jones tweeted a link to the legislation.  Here's an excerpt from Amazon.com's email: "Dear Colorado-based Amazon Associate: We are writing from the Amazon Associates Program to inform you that the Colorado government recently enacted a law to impose sales tax regulations on online retailers. The regulations are burdensome and no other state has similar rules. The new regulations do not require online retailers to collect sales tax. Instead, they are clearly intended to increase the compliance burden to a point where online retailers will be induced to "voluntarily" collect Colorado sales tax -- a course we won't take. We and many others strongly opposed this legislation, known as HB 10-1193, but it was enacted anyway. Regrettably, as a result of the new law, we have decided to stop advertising through Associates based in Colorado. We plan to continue to sell to Colorado residents, however, and will advertise through other channels, including through Associates based in other states. There is a right way for Colorado to pursue its revenue goals, but this new law is a wrong way. As we repeatedly communicated to Colorado legislators, including those who sponsored and supported the new law, we are not opposed to collecting sales tax within a constitutionally-permissible system applied even-handedly. The US Supreme Court has defined what would be constitutional, and if Colorado would repeal the current law or follow the constitutional approach to collection, we would welcome the opportunity to reinstate Colorado-based Associates. You may express your views of Colorado's new law to members of the General Assembly and to Governor Ritter, who signed the bill. Your Associates account has been closed as of March 8, 2010, and we will no longer pay advertising fees for customers you refer to Amazon.com after that date. Please be assured that all qualifying advertising fees earned prior to March 8, 2010, will be processed and paid in accordance with our regular payment schedule. Based on your account closure date of March 8, any final payments will be paid by May 31, 2010. We have enjoyed working with you and other Colorado-based participants in the Amazon Associates Program, and wish you all the best in your future.   Best Regards,   The Amazon Associates Team"

• Leading an offshore team

  - by Chuck Conway

  I'm in a position where I am leading two teams of 4. Both teams are located in India. I am on the west coast of the U.S. I'm finding leading remote teams challenging: First, their command of the English language is weak. Second, I'm having difficultly understanding them through their accents. Third is timing, we are 12 hours apart. We use Skype to communicate. I have a month to get the project done. We've burned through a week just setting up the environments. At this point I'm considering working their hours, 11p PDT to 7a PDT, to get them up to speed, so that I can get the project off the ground. A 12 hour lag time is too much. I'm looking for steps I can take to be successful at leading an offshore team. Update The offshore team's primary task is coding, of course, most coding tasks do involve some design work. The offshore team's are composed of one lead, 2 mid level (4 to 5 years) developers and a junior (~2 years) developer. The project is classic waterfall. We've handed the offshore team a business and a technical design document. We are trying to manage the offshore in an agile way. We have daily conference calls with them and I'm requiring the teams to send me a daily scrum in the form of an email answering the following questions: What did I do today? What am I going to do tomorrow? What do I need from Chuck so I can do my job tomorrow? There is some ambiguity in the tasks. The intent was to give them enough direction for them to develop the task with out writing the code for them. I don't have a travel budget. I am using Fogbugz to track the tasks. Each task has been entered into Fogbugz and given a priority. Each team member has access to FogBugz and can choose what task they wish to complete. Related question: What can we do to improve the way outsourcing/offshoring works? Update 2 I've decided that I can not talk to the team once a day. I must work with them. Starting tonight I've started working the same hours they are. This makes me available to them when they have questions. It also allows me to gain their trust and respect.

• Recieving and organizing results without server side script (JavaScript)

  - by Aaron

  I have been working on a very large form project for the past few days. I finally managed to get tables to work properly within a javascript file that opens a new display window. Now the issue at hand is that I can't seem to get CSS code to work within the javascript that I have created. Before everyone starts thinking "just use server side script idiot" I have a few conditions and info about the file: The file is only being ran local due to confidential information risks. Once again no option for server access. The intranet the computers are on are already top security and this wouldn't exactly be a company wide program The code below is obviously just a demo with a simple form... The real file has six pages of highly confidential information Only certain fields on this form will actually be gathered (example: address doesnt appear in the results) The display page will contain data compiled into tables for easier viewing I need to be able to create css commands to easily detect certain information if it applies and along with matching design of the original form Here is the code: <html> <head> <title>Form Example</title> <script LANGUAGE="JavaScript" type="text/javascript"> function display() { DispWin = window.open('','NewWin', 'toolbar=no,status=no,width=800,height=600') message = "<body>"; message += "<table border=1 width=100%>"; message += "<tr>"; message += "<th colspan=2 align=center><font face=stencil color=black><h1>Results</h1><h4>one</h4></font>"; message += "</th>"; message += "</tr>"; message += "<td width=50% align=left>"; message += "<ul><li><b><font face=calibri color=red>NAME:</font></b> " + document.form1.yourname.value + "</UL>" message += "</td>"; message += "<td width=50% align=left>"; message += "<li><b>PHONE: </b>" + document.form1.phone.value + "</ul>"; message += "</td>"; message += "</table>"; message += "<body>"; DispWin.document.write(message); DispWin.document.body.style.cssText = 'color:#blue;'; } </script> </head> <body> <h1>Form Example</h1> Enter the following information: <form name="form1"> <p><b>Name:</b> <input TYPE="TEXT" SIZE="20" NAME="yourname"> </p> <p><b>Address:</b> <input TYPE="TEXT" SIZE="30" NAME="address"> </p> <p><b>Phone: </b> <input TYPE="TEXT" SIZE="15" NAME="phone"> </p> <p><input TYPE="BUTTON" VALUE="Display" onClick="display();"></p> </form> </body> </html> >

• Filter rule for SMS / text messages in exchange active sync (SMS sync)

  - by kynan

  Exchange server 2010 introduces SMS Sync (via exchange active sync), which works fine with my android device and the Samsung email app. However, all text messages are synced to my exchange inbox, which is a pain. I'd like to have them filtered to a specific folder. So far, I haven't figured out a useful filter rule for achieving that, since there seems to be no header indicating it's a text message. Has anyone managed to do that? Note that I'm not using Outlook as an email client, so I'm specifically looking for a server-side rule.

• How is this modsec rule getting triggered?

  - by BipedalShark

  I made a GET request to the URL, http://domain.tld/test/docs/index.php?create_table=1&step=2 and got a 403 response code. It turns out this modsec rule is getting triggered: Access denied with code 403 (phase 2). Pattern match "(?:ogg|gopher|zlib|(?:ht|f)tps?)\:/" at ARGS:gltr_redir. [file "/opt/mod_security/10_asl_rules.conf"] [line "827"] [id "340153"] [rev "22"] [msg "Generic PHP code injection protection via ARGS 3"] [severity "CRITICAL"] I would assume ARGS refers to GET/POST data, but there's no gltr_redir in the query string. And, being a GET request, there's obviously no POST data. So how is this rule being triggered?

• automatic reply rule within Outlook

  - by jherlitz

  My plan is to add a automatic reply to all incoming emails for a exchange mailbox. I created a rule that would check all incoming and created the template reply. Created it so it would match a server rule so outlook would not have to be open. If I send an email from my work account on the same exchange server, it works and sends the reply I created. With outlook open or closed. However, when I send email from outside the company, (my personal email), it does not get a reply. What the heck is going on there? I think the issue is within the selection of who the email is too. I have tried "only to me" "where my name is in TO or CC" as well as "sent to people or distribution list". So any ideas of why this isn't working. I thought this question was a super user question as appose to server fault. Thank you,

• Transport rule - Exchange 2010

  - by Jeff

  I have two transport rules on my exchange server. One is: > Apply rule to messages: From users that are 'outside the organization' > and when any of the recipients in the To or Cc fields is a member of > '[email protected]' Forward the messageto sender's manager > for moderation The second is: Apply rule to messages from a member of '[email protected]' and sent to users that are 'outside the organization' forward the message to the sender's manager for moderation. nointernetmail is a distribution group, and each user has the managed by set to there local manager. However these transport rules do not work, internet mail is still sent and received without issue. I have read various tutorials / articles of how to do this on sites such as msexchangeblog and even microsoft technet, however even after following the guides I am still unable to have this function properly. Any help is appreciated.

• pf not execute udp port specific block rule

  - by seaquest

  The traffic I want to block can be sniffed as below with tcpdump: 19:16:22.391164 IP 95.95.95.95.2036 > 10.10.10.10.443: UDP, length 8192 So I wanted to write a rule block any udp destination port 443 traffic. block drop quick on igb3 inet proto udp to any port 443 Traffic does not match and does not blocked. However, It matches and blocks if I write rule as below: block drop quick on igb3 inet proto udp to 10.10.10.10 Do you have any remarks? I am using pf in Freebsd.

• Privoxy rule to block Facebook spying

  - by bignose

  Recently, my server's Privoxy rules to block Facebook's spying have failed. How can I block current Facebook spying links? Since soon after [the inception of Facebook's so-called “Open Graph” cross-site tracking widgets][1] (those “Like” bugs on numerous websites), I blocked them by using this rule (in user.action) on our site's Privoxy server: { +block-as-image{People-tracking button.} } .facebook.com/(plugins|widgets)/(like|fan).* That worked fine; the spying bugs no longer appeared on any web page. Today I noticed that they're all making it past that filter [edit: no, they're not]. SOLUTION: The proxy was being silently ignored, though this was not obvious in the client. The above rule continues to work fine.

• IIS7 Rewrite rule being duplicated across 2 different websites (unwanted)

  - by Matt

  We have a IIS7 on Windows Server 2008. It is hosting a handful of sites, on a handful of ip addresses. 2 of those sites are actually wildcards on the domain: *.firstdomain.com *.seconddomain.com However, I am finding that any URL Rewrite rules I add for one of these "websites", is automatically in the URL Rewrite section for the other. Similarly, if I disable the rule in in one, it disables in the other. This doesn't happen with the other sites defined on this server, just these two. I look at the parent (top level, the server as a whole), and the rule is not there. Any idea what's going on here?

• Custom Rule Sets in JohnTheRipper

  - by user854619

  I'm trying to create a custom rule set to do hash cracking. I have a SHA1 hash and a rule set that was enforced to create the password. The password must be of the form, 6-8 characters Every other letter changes case Password "shifts" characters at least one degree and at most three One odd number and one even number are at the beginning of the password One special character and one punctuation character are appended to the end of the password How can I defined a brute force attack in JohnTheRipper or similar hash cracking program? I've also attempted to write code to generate a wordlist of possible passwords, with no success. Thanks!
