• bash command history update before execution of command

  - by Jon

  Hi, Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT. However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again). I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm? Thanks, Jon

• How to re-use a thread in Java ?

  - by David

  I am a building a console Sudoku Solver where the main objective is raw speed. I now have a ManagerThread that starts WorkerThreads to compute the neibhbors of each cell. So one WorkerThread is started for each cell right now. How can I re-use an existing thread that has completed its work? The Thread Pool Pattern seems to be the solution, but I don't understand what to do to prevent the thread from dying once its job has been completed. ps : I do not expect to gain much performance for this particular task, just want to experiment how multi-threading works before applying it to the more complex parts of the code. Thanks

• is there a such thing as a randomly accessible pseudo-random number generator? (preferably open-sour

  - by lucid

  first off, is there a such thing as a random access random number generator, where you could not only sequentially generate random numbers as we're all used to, assuming rand100() always generates a value from 0-100: for (int i=0;i<5;i++) print rand100() output: 14 75 36 22 67 but also randomly access any random value like: rand100(0) would output 14 as long as you didn't change the seed rand100(3) would always output 22 rand100(4) would always output 67 and so on... I've actually found an open-source generator algorithm that does this, but you cannot change the seed. I know that pseudorandomness is a complex field; I wouldn't know how to alter it to add that functionality. Is there a seedable random access random number generator, preferably open source? or is there a better term for this I can google for more information? if not, part 2 of my question would be, is there any reliably random open source conventional seedable pseudorandom number generator so I could port it to multiple platforms/languages while retaining a consistent sequence of values for each platform for any given seed?

• .NET Regular expressions on bytes instead of chars

  - by brickner

  Hi, I'm trying to do some parsing that will be easier using regular expressions. The input is an array (or enumeration) of bytes. I don't want to convert the bytes to chars for the following reasons: Computation efficiency Memory consumption efficiency Some non-printable bytes might be complex to convert to chars. Not all the bytes are printable. So I can't use Regex. The only solution I know, is using Boost.Regex (which works on bytes - C chars), but this is a C++ library that wrapping using C++/CLI will take considerable work. How can I use regular expressions on bytes in .NET directly, without working with .NET strings and chars? Thank you.

• How to convert JavaScript dictionary into Python syntax

  - by Sputnix

  Writing out javascript dictionary from inside of JavaScript- enabled application (such as Adobe) into external .jsx file (or any other .txt file) the context of resulted file dictionary looks like: ({one:"1", two:"2"}) (Please note that each dictionary keys are written as they are the variables name (which is not true). A next step is to read this .jsx file with Python. I need to find a way to convert ({one:"1", two:"2"}) into Python dictionary syntax such as: {'one':"1", 'two':"2"} It has been already suggested that instead of using JavaScript's built-in dict.toSource() it would make more sense to use JSON which would write a dictionary content in similar to Python syntax. But unfortunately using JSON is not an option for me. I need to find a way to convert ({one:"1", two:"2"}) into {'one':"1", 'two':"2"} using Python alone. Any suggestions on how to achieve it? Once again, the problem mostly in dictionary keys syntax which inside of Python look like variable names instead of strings-like dictionary keys names: one vs "one"

• Converting DAO to ADO

  - by webworm

  I am working with an Access 2003 database that has a subroutine using DAO code. This code loops through the table definitions and refreshes the ODBC connection string. I would like to convert this to ADO so I do not have to reference the DAO object library. Here is the code ... Public Sub RefreshODBCLinks(newConnectionString As String) Dim db As DAO.Database Dim tb As DAO.TableDef Set db = CurrentDb For Each tb In db.TableDefs If Left(tb.Connect, 4) = "ODBC" Then tb.Connect = newConnectionString tb.RefreshLink Debug.Print "Refreshed ODBC table " & tb.Name End If Next tb Set db = Nothing MsgBox "New connection string is " & newConnectionString, vbOKOnly, "ODBC Links refreshed" End Sub The part I am unsure of is how to loop through the tables and get/set their connection strings.

• Clean Up Controller, Update Item Quantity within Cart

  - by Karl Entwistle

  Hi guys I was wondering if anyone could help me out, I need to clean up this controller as the resulting code to simply update an items quantity if it already exists seems way too complex. class LineItemsController < ApplicationController def create @product = Product.find(params[:product_id]) if LineItem.exists?(:cart_id => current_cart.id) item = LineItem.find(:first, :conditions => [ "cart_id = #{@current_cart.id}"]) LineItem.update(item.id, :quantity => item.quantity + 1) else @line_item = LineItem.create!(:cart => current_cart, :product => @product, :quantity => 1, :unit_price => @product.price) flash[:notice] = "Added #{@product.name} to cart." end redirect_to root_url end end ` As always any help is much appreciated, the code should be fairly self explanatory, thanks :) PS posted it here as well as it looks a bit funny on here http://pastie.org/994059

• If you are forced to use an Anemic domain model, where do you put your business logic and calculated

  - by Jess

  Our current O/RM tool does not really allow for rich domain models, so we are forced to utilize anemic (DTO) entities everywhere. This has worked fine, but I continue to struggle with where to put basic object-based business logic and calculated fields. Current layers: Presentation Service Repository Data/Entity Our repository layer has most of the basic fetch/validate/save logic, although the service layer does a lot of the more complex validation & saving (since save operations also do logging, checking of permissions, etc). The problem is where to put code like this: Decimal CalculateTotal(LineItemEntity li) { return li.Quantity * li.Price; } or Decimal CalculateOrderTotal(OrderEntity order) { Decimal orderTotal = 0; foreach (LineItemEntity li in order.LineItems) { orderTotal += CalculateTotal(li); } return orderTotal; } Any thoughts?

• What web server should I use if I want to run Java code behind it?

  - by Boaz

  At the moment, I have lot's of Java which does all kind of nifty stuff and I'm happy with it. The code is command line driven which have been great so far, but I recently decided I want to make the functionality available through web-services. Since my is complex and I'm happy with the way it's written , I don't want go through the pain of porting it to other languages. So I set out on a google journey to find out what web servers exist (on a Linux machine, though it's interesting to hear the answer without that limitation). From what I could find, it seems that there are two viable options: Apache Tomcat and Sun Java Server. What are the reason to choose one on top of the other? what are the strength of each and what are the weaknesses? Or, perhaps, there is a third one which is much easier, flexible and less cumbersome. Anyone?

• ASP.NET MVC based CMS - dynamic generation of form helpers

  - by user252160

  I am working on an ASP.NET MVC based CMS that presents a rather extreme case. The system must allow the user to add custom content types based on different fields, and for every field, one can add options and validations. The thing is that everything is stored in a complex DB and extracted at runtime using LINQ. I am pretty fresh with ASPNET MVC so the following dilemma came to mind How should I make the content creation view so that form helpers are not predefined int he view code but are loaded based on the type of the field ? Do I have to create a factory class that checks the value of the type property of the field, and then returns a helper based on that or there's a better way to do it. This one seems pretty rigid to me , because anytime I make a change in the Fieldtypes table, I will have to make sure to create a check for that new type too.

• Types in Python - Google Appengine

  - by Chris M

  Getting a bit peeved now; I have a model and a class thats just storing a get request in the database; basic tracking. class SearchRec(db.Model): WebSite = db.StringProperty()#required=True WebPage = db.StringProperty() CountryNM = db.StringProperty() PrefMailing = db.BooleanProperty() DateStamp = db.DateTimeProperty(auto_now_add=True) IP = db.StringProperty() class AddSearch(webapp.RequestHandler): def get(self): searchRec = SearchRec() searchRec.WebSite = self.request.get('WEBSITE') searchRec.WebPage = self.request.get('WEBPAGE') searchRec.CountryNM = self.request.get('COUNTRY') searchRec.PrefMailing = bool(self.request.get('MAIL')) searchRec.IP = self.request.get('IP') Bool has my biscuit; I thought that setting bool(self.reque....) would set the type of the string but no matter what I pass it it still stores it as TRUE in the database. I had the same issue with using required=True on strings for the model; the damn thing kept saying that nothing was being passed... but it had. Ta

• A public web API: What do developers prefer to consume?

  - by spender

  We've got a bunch of data that we'd like to expose to the world hosted on an asp-net.mvc website. I'd like to ensure that we deliver it using technology that is easy for end developers to implement and not tied to any particular platform, rather than using technology that is unpopular/incompatible with developers. The kind of requests we expect are mainly to retrieve search results (not many parameters), but down the like we'd like to be able to provide catalogue lookups and the like, which may be more complex. Bearing this in mind, what is the preferred means of doing this?

• How to insert bulk data into mysql table from asp.net at once.

  - by kranthi

  Hi, I have a requirement that I need to read an excel sheet using asp.net/C# and insert all the records into mysql table.The excel sheet consists of around 2000 rows and 50 columns. Currently,upon reading the excel records ,I am inserting the records one by one using a prepare statement into mysql table.But its taking around 70 secs to do so because of the huge data. I've also thought of creating a new datarow, assigning values to each cell,adding the resulting datarow to datatable and finally calling dataadapter.update(...).But it seems to be complex because I got around 50 columns and hence I'll have to assign 50 values to the datarow. Could someone please suggest if there is an alternate to improve the performance of the insertion? Thanks

• Safest way to change variable names in a project

  - by kamziro

  So I've been working on a relatively large project by myself, and I've come to realise that some of the variable names earlier on were.. less than ideal. But how does one change variable names in a project easily? Is there such a tool that can go through a project directory, parse all the files, and then replace the variable names to the desired one? It has to be smart enough to understand the language I imagine. I was thinking of using regexp (sed/awk on linux?) tools to just replace the variable name, but there were many times where my particular variable is also included as a part of strings. There's also the issue about changing stuff on a c++ namespace, because there is actually two classes in my project that share the same name, but are in different namespaces. I remember visual stuio being able to do this, but what's the safest and most elegant way to do this on linux?

• not returning anything from postgresql function?

  - by netllama

  Is it possible for a PostgreSQL plpgsql function to not return anything? I've created a function, and I don't need it to return anything at all, as it performs a complex SQL query, and inserts the results of that query into another table (SELECT INTO ....). Thus, I have no need or interest in having the function return any output or value. Unfortunately, when I try to omit the RETURN clause of the function declaration, I can't create the function. Is it possible for a PostgreSQL plpgsql function to not return anything?

• How should I handle incomplete packet buffers?

  - by Benjamin Manns

  I am writing a client for a server that typically sends data as strings in 500 or less bytes. However, the data will occasionally exceed that, and a single set of data could contain 200,000 bytes, for all the client knows (on initialization or significant events). However, I would like to not have to have each client running with a 50 MB socket buffer (if it's even possible). Each set of data is delimited by a null \0 character. What kind of structure should I look at for storing partially sent data sets? For example, the server may send ABCDEFGHIJKLMNOPQRSTUV\0WXYZ\0123!\0. I would want to process ABCDEFGHIJKLMNOPQRSTUV, WXYZ, and 123! independently. Also, the server could send ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890LOL123HAHATHISISREALLYLONG without the terminating character. I would want that data set stored somewhere for later appending and processing. Also, I'm using asynchronous socket methods (BeginSend, EndSend, BeginReceive, EndReceive) if that matters.

• XmlSerializer Performance Issue when Specifying XmlRootAttribute

  - by Dougc

  I'm currently having a really weird issue and I can't seem to figure out how to resolve it. I've got a fairly complex type which I'm trying to serialize using the XmlSerializer class. This actually functions fine and the type serializes properly, but seems to take a very long time in doing so; around 5 seconds depending on the data in the object. After a bit of profiling I've narrowed the issue down - bizarrely - to specifying an XmlRootAttribute when calling XmlSerializer.Serialize. I do this to change the name of a collection being serialized from ArrayOf to something a bit more meaningful. Once I remove the parameter the operation is almost instant! Any thoughts or suggestions would be excellent as I'm entirely stumped on this one!

• Excel Autofilter in VB.NET

  - by Fabri

  In my application I'm exporting an Excel file by getting the layout of a HTML page. So, in my codebehind, I'm modifying the HTML layout and inserting itens on it like if it was a webpage. Doing it that way, I don't need to use any external library and, as the data I'm exporting is just a table, I don't need nothing complex to handle it. My question is: there is a way to create an AutoFilter by just modifying the HTML tags? I mean, like if a put a < bColumn Name in the HTML, when exporting to Excel it will become Bold, it is possible to do the same thing with the AutoFilter?

• Redirect away from HTTPS with ASP.NET MVC App

  - by Amadiere

  I'm using ASP.NET MVC 2 and have a login page that is secured via HTTPS. To ensure that the user always accesses those pages via SSL, I've added the attribute [RequiresHttps] to the controller. This does the job perfectly. When they have successfully logged in, I'd like to redirect them back to HTTP version. However, there isn't a [RequiresHttp] attribute and I'm struggling to get my head around how I might achieve this. The added (potential) complication is that the website when in production is hosted at the route of the domain, but for development and testing purposes it is within a sub directory / virtual directory / application. Am I over-thinking this and is there an easy solution staring me in the face? Or is it a little more complex?

• How to easily pass a very long string to a worker process under Windows?

  - by sharptooth

  My native C++ Win32 program spawns a worker process and needs to pass a huge configuration string to it. Currently it just passes the string as a command line to CreateProcess(). The problem is the string is getting longer and now it doesn't fit into the 32K characters limitation imposed by Windows. Of course I could do something like complicating the worker process start - I use the RPC server in it anyway and I could introduce an RPC request for passing the configuration string, but this will require a lot of changes and make the solution not so reliable. Saving the data into a file for passing is also not very elegant - the file could be left on the filesystem and become garbage. What other simple ways are there for passing long strings to a worker process started by my program on Windows?

• simple regex to splice out text in ruby

  - by user141146

  I'm using ruby and I want to splice out a piece of a string that matches a regex (I think this is relatively easy, but I'm having difficulty) I have several thousand strings that look like this (to varying degrees) my_string = "adfa <b>weru</b> orua fklajdfqwieru ofaslkdfj alrjeowur woer woeriuwe <img src=\"/images/abcde_111-222-333/111-222-333.xml/blahblahblah.jpg\" />" I would like to splice out the /111-222-333.xml (the value of this changes from string to string, but suffice it to say is that I want to remove the piece between 2 forward slashes that contains something.xml. my hope was to find a match like this my_match = my_string.match(/\/.+?\.xml\//) but this actually captures "/b> orua fklajdfqwieru ofaslkdfj alrjeowur woer woeriuwe <img src=\"/images/abcde_111-222-333/111-222-333.xml/" I assumed that .+? would match what I am looking for, but it seems like it starts with the first forward slash that it finds (even though it's non-greedy) and then expands forward to the ".xml"). Any thoughts on what I'm doing wrong? TKS!!

• Converting String^ and Collection of String^ to const char*

  - by Jim Jones

  Using VS2008 Managed C++ to wrap a dll. The native method takes a series of single const char* values and a collection of char* values. Going to make an example function: Function1(char * value1, TF_StringList& catList); TF_StringList is a dll class with 3 insert methods, the one I want to use is: TF_StringList::insert(const char* str); So I set up a wrapper method of: WrapperClass::callFunction(String^ mvalue1, ArrayList mcatList); mvalue1 is converted to const char* using: const char* value1 = (char*)(Marshal::StringToHGlobalAnsi(mvalue1)).ToPointer(); However, when a get to the collection of strings, I iterate over it getting each string using the index: String^ mstr = mcatList[i]; Have tried every way of converting String^ to const char* and in every case the TF_StringList::insert(const char* str) method throws a C2663 error which has to do with the const-ness of the value. What is the problem?

• How do I protect myself?

  - by ved

  I was poking around at my work computer this evening and was looking at my timesheets. I noticed that all my timesheets had variables in the URLs and I could figure out the numbering scheme for the pages. Then I got a little curious about SQL injection and thought of trying out adding simple SQL injections like "OR 1=1" etc. to see how protected we really were with our timesheet info. One of these strings yielded a friendly error page saying that an error email was sent to the developer. I am concerned that my ID, and request will be seen by the developer , immediately recognized as SQL injection and will be reported to network security officer as a malicious attempt by an employee to hack the timesheet dB. what is my defense? I am really worried.

• Lua : Dynamicly calling a function with arguments.

  - by Tipx

  Using Lua, I'm trying to dynamicly call a function with parameters. What I want to have it done is I send a string to be parsed in a way that : 1st argument is a class instance "Handle" 2nd is the function to be called All that is left are arguments "modules" is a a table like { string= } split() is a simple parser that returns a table with indexed strings function Dynamic(msg) local args = split(msg, " ") module = args[1] table.remove(args, 1) if module then module = modules[module] command = args[1] table.remove(args, 1) if command then if not args then module[command]() else module[command](unpack(args)) -- Reference 1 end else -- Function doesnt exist end else -- Module doesnt exist end end When I try this with "ignore remove bob", by "Reference 1", it tries to call "remove" on the instance associated with "ignore" in modules, and gives the argument "bob", contained in a table (with a single value). However, on the other side of the call, the remove function does not receive the argument. I even tried to replace the "Reference 1" line with module[command]("bob") but I get the same result.
