• Creating a new buffer with text using EmacsClient

  - by User1

  I have a program that can send text to any other program for further analysis (eg sed, grep, etc). I would like it to send the data to Emacs and do analysis there. How would I do that? EmacsClient takes a filename by default, this is a data string not a file and I really don't want to create and delete files just to send data to Emacs. EmacsClient has an "eval" command-line option that let's you execute lisp code instead of open files. Is there a simple lisp function that will open a new buffer with the given text?

• Python, implementing proxy support for a socket based application (not urllib2)

  - by Terry Felkrow

  Hey guys, I am little stumped: I have a simple messenger client program (pure python, sockets), and I wanted to add proxy support (http/s, socks), however I am a little confused on how to go about it. I am assuming that the connection on the socket level will be done to the proxy server, at which point the headers should contain a CONNECT + destination IP (of the chat server) and authentication, (if proxy requires so), however the rest is a little beyond me. How is the subsequent connection handled, specifically the reading/writing, etc... Are there any guides on proxy support implementation for socket based (tcp) programming in Python? Thank you

• how to simplify this database update query (php)

  - by krike

  How could I simplify this update instruction? Whenever a client buys an item it will update the sales with 1. $this->db->query('SELECT amount FROM shop_items WHERE itemid='.$itemid.''); $new_amount = $item->amount+1; if(!$this->db->query('UPDATE shop_items SET amount='.$new_amount.' WHERE itemid='.$itemid.'')): return false; endif; Can't I make it more simple so there are less lines, for example: if(!$this->db->query('UPDATE shop_items SET amount=_current_value_+1 WHERE itemid='.$itemid.'')): return false; endif; is this possible? if not thanks anyway

• MySQL query : all records of one table plus count of another table

  - by Ricardo

  Hello Guys! I have 2 tables: User and Picture. The Picture table has the key of the user. So basically each user can have multiple pictures, and each picture belongs to one user. Now, I am trying to make the following query: I want to select all the user info plus the total number of pictures that he has (even if it's 0). How can I do that? Probably it sounds quite simple, but I am trying and trying and can't seem to find the right query. The only thing I could select is this info, but only for users that have at least 1 picture, meaning that the Pictures table has at least one record for that key... But I also wanna consider the users that don't have any. Any idea? Thanks!

• How to run lengthy tasks from an ASP.NET page?

  - by Jimmy C

  I've got an ASP.NET page with a simple form. The user fills out the form with some details, uploads a document, and some processing of the file then needs to happens on the server side. My question is - what's the best approach to handling the server side processing of the files? The processing involves calling an exe. Should I use seperate threads for this? Ideally I want the user to submit the form without the web page just hanging there while the processing takes place. I've tried this code but my task never runs on the server: Action<object> action = (object obj) => { // Create a .xdu file for this job string xduFile = launcher.CreateSingleJobBatchFile(LanguagePair, SourceFileLocation); // Launch the job launcher.ProcessJob(xduFile); }; Task job = new Task(action, "test"); job.Start(); Any suggestions are appreciated.

• preg_match not defined in php4 in openwrt?

  - by user2723949

  I have installed the packages PHP4 and PHP4-CGI in openwrt through command line (opkg install) when I tried this simple code by putting this in the openwrt www folder, <?php $subject = "abcdef"; $pattern = '/^def/'; preg_match($pattern, $subject, $matches, PREG_OFFSET_CAPTURE, 3); print_r($matches); ?> I got this error Fatal error: Call to undefined function: preg_match() in /www/phptest.php on line 4 but php manual says preg_match() is defined in php4 also.. What might be the reason for this error? Is there any other PHP module that is to be installed? Or is there any alternate method for preg_match?

• Child service not writing to event log

  - by Tommy Fisk

  I am having a very simple (but incredibly frustrating) issue with a parent service and the child service. Let's call the parent service "Service A" and the child "Service B". Both services reside on the same box. Using WCF Storm, when I send Service B a message, I see lots of entries in the event viewer for it. However, if I send a message to Service A, which calls Service B, I only see entries from Service A. So for some reason, the child logs are not written when the parent calls it, but if I call it myself, the logs do indeed show up, so I know it's not a problem with the logging or anything like that. Here is what I am using to write to the event log. // in some random static class private static EventLog el = new EventLog(); el.WriteEntry("In " + location + ", " + message); // params passed in Does anyone know why this is happening? And more importantly what I can do about it?

• How do I group a SSRS report by month?

  - by Anthony K

  I have a set of data that includes a field with the datetime that events happen. i want to group the events by month. I haven't come across a simple and elegant expression to achieve this. So far all I can come up with is to convert the field to a date, then take the year and month as integers and then convert this back to a string with the day set to 1. In Crystal Reports I would group on the datetime field and then set the period to month, very easy. I am sure there is an easy answer to this that I haven't been able to find.

• Communication via internet in Java

  - by Stuart

  What I mean is like servers on video games. You can run an application and it will set up a server on your computer with an IP and a port. For example, how would you make an application where one host application sets up a thing where it has an IP and a port, and another computer that has access to the internet as well can type in the IP and port and it would be able to communicate with the host? I mean simple communication, like sending a boolean or String. And would there be any security problems that would be needed to fix?

• Regex expression with leading zero

  - by user1874087

  I'm rather new to regex expressions and need help with a simple expression. I'm using Pentaho for ETL (Replace in String transformation) and I have column values that I need to add leading zeros to and parse out text as part of the database import. So far I have been unable to add the leading zero. The column is called Region and the values are "region 8", "region 10", "region 11". My regex expression is ['Region'] which will eliminate the region text but produces results = "8", "10", "11". I need values to produce "08", "10", "11". So all the single digit numbers must have leading zeros.

• R storing a complex search as a string

  - by Tahnoon Pasha

  Hi I'm working with a large data frame that I frequently need to subset in different combinations of variables. I'd like to be able to store the search in a string so I can just refer to the string when I want to see a subset. x = read.table(textConnection(" cat1 cat2 value A Z 1 A Y 2 A X 3 B N 2"),header=T,strip.white=T) search_string="cat1== 'A' & cat2=='Z'" with(x,subset(x,search)) doesn't work. What I'd be looking for is the result of a search similar to the one below. with(x,subset(x,cat1=='A' & cat2=='Z')) I'd prefer not to just create multiple subsetted data frames at the start if another solution exists. Is there a simple way to do what I'm trying?

• Ruby on Rails when create method fails, render loses local variables

  - by Jimmy

  Hey guys I have a simple create method with some validations and whenever the create method fails due to validation errors it re-renders the 'new' action. The problem is in my new action/view I have a local variable that is established in the action and passed to a partial to render some related information to what the user is creating. Now when my create action fails and I try to re-render the 'new' action I'm getting the always awesome undefined method `cover' for nil:NilClass error. What is the best way to handle re-establishing my action's local variables on a render instead of redirecting to the action again and the user losing the data they input?

• HTTP request stream not readable outside of request handler

  - by Jason Young

  I'm writing a fairly complicated multi-node proxy, and at one point I need to handle an HTTP request, but read from that request outside of the "http.Server" callback (I need to read from the request data and line it up with a different response at a different time). The problem is, the stream is no longer readable. Below is some simple code to reproduce the issue. Is this normal, or a bug? function startServer() { http.Server(function (req, res) { req.pause(); checkRequestReadable(req); setTimeout(function() { checkRequestReadable(req); }, 1000); setTimeout(function() { res.end(); }, 1100); }).listen(1337); console.log('Server running on port 1337'); } function checkRequestReadable(req) { //The request is not readable here! console.log('Request writable? ' + req.readable); } startServer();

• Git - Committing Machine Specific Configuration Files

  - by Gordon

  A common scenario when I develop is that the codebase will have several config files which require machine specific settings. These files will be checked into Git and other developers will always accidentally check them back in and break someone else's configuration. A simple solution to this would be to just not check them in to Git, or even to additionally add a .gitignore entry for them. However, I find that it is much more elegant to have some sensible defaults in the file which the developer can modify to suit his needs. Is there an elegant way to make Git play nicely with such files? I would like to be able to modify a machine-specific configuration file and then be able to run "git commit -a" without checking that file in.

• Can I have code that executes before and after tests are run by NUnit?

  - by Billy ONeal

  I've got a bunch of tests in NUnit which create garbage data on the filesystem (bad, I know, but I have little control over this). Currently we have a cleanup tool that removes these temporaries and such, but I'd like to be able to run that cleanup tool automatically. I'd have to be able to run it after all tests have finished running. I have similar checking that I'd like to do at the beginning, to ensure that there are none of these temporaries left from previous runs that might change the outcome of the tests. Is such a thing simple or am I going to have to implement a whole new test runner for such a thing?

• Shouldn't this cause an Overflow? It doesn't!

  - by Cyberherbalist

  What's up with this, anyway? I do a simple multiplication: Int64 x = 11111111111; Int64 y = 11111111111; Int64 z = x * y; And at the end of the multiplication, z shows a value of: -5670418394979206991 This has clearly overflowed, but no exception is raised. I'd like one to be raised, but... Note that this is on Windows Phone 7, but I don't think this has any bearing on the issue. Or does it?

• MS Access questions - Scalability / indexing / transactions

  - by oo

  A few questions on MS Access databases - Size: Are there limits to the size of an access database? The reason i ask is that we have an access database that has a few simple tables. The size of the db is about 1GB. When I do a query on it, i see it taking over 10 minutes to run. With proper indexing, should MS Access be able to handle this or are there fundamental limitations to the technology. This is MS Access XP. Also, does MS Access support db transactions, commit and rollback?

• How can I "override" deepcopy in Python?

  - by Az

  Hi there, I'd like to override __deepcopy__ for a given SQLAlchemy-mapped class such that it ignores any SQLA attributes but deepcopies everything else that's part of the class. I'm not particularly familiar with overriding any of Python's built-in objects in particular but I've got some idea as to what I want. Let's just make a very simple class User that's mapped using SQLA. class User(object): def __init__(self, user_id, name): self.user_id = user_id self.name = name I've used dir() to see, before and after mapping, what SQLAlchemy-specific attributes there are and I've found _sa_class_manager and _sa_instance_state. Provided those are the only ones how would I ignore that when defining __deepcopy__? Also, are there any attributes the SQLA injects into the mapped object? (I asked this in a previous question (as an edit a few days after I selected an answer to the main question, though) but I think I missed the train there. Apologies for that.)
