• XML Import how would you do it?

  - by Rico

  XML is used as one of our main integration points. it comes over by many clients at a time but too many clients importing at the same time can slow down our database to a crawl. Someone has to have solved a problem like this. I am basically using VB to parse through the data and import what i want and don't want. Is there a better way?

• Why would I use Scala/Lift over Java/Spring?

  - by Chris J

  Hi, I know this question is a bit open but I have been looking at Scala/Lift as an alternative to Java/Spring and I am wonder what are the real advantages that Scala/Lift has over it. From my perspective and experience, Java Annotations and Spring really minimizes the amount of coding that you have to do for an application. Does Scala/Lift improve upon that?

  Windows Server don't connect to network share. Network share is work.

• What is this weird script I found on facebook?

  - by Mike Turley

  Not so much a question to help my own programming, but I found this page on facebook with a cool illusion and a page that says "to see the real illusion, copy and paste this code into your address bar" and there is a script: http://pastebin.com/LQUVQ8hm What the hell is this? What would happen if I put it in my address bar, which I assume would be a very unwise idea? I am confused.

• Mysql - GROUP BY Avoid using tempoary

  - by jwzk

  The goal of this query is to get a total of unique records (by IP) per ref ID. SELECT COUNT(DISTINCT ip), GROUP_CONCAT(ref.id) FROM `sess` sess JOIN `ref` USING(row_id) WHERE sess.time BETWEEN '2010-04-21 00:00:00' AND '2010-04-21 23:59:59' GROUP BY ref.id ORDER BY sess.time DESC The query works fine, but its using a temporary table.

• Automatic form generation software

  - by Jonathan

  Hi! I'm using winforms. I spend a lot of time drawing forms (maybe not a lot, but it is a boring task). To sum up... I want to develop a simple aplication that connect to a sql server database, let the user to select a table, and put the controls in a form for me (generate the designer code), based on the tipe of each column. Then my app will name each control like the column of the table, set the maxlengh property (if the type is varchar), and create a label with the same text near the control. If the column is a FK, then the app will draw a combobox and so on. I saw that Telerik Open ORM make something like this, but I only need a simple app for the IU Generation. If the same day I finish my little application I discover a tool that make the same... I will feel myself stupid :D Are there any tool out there that do this work for me? Thanks

• Console output spits out Chinese(?) characters

  - by a_person

  This is a real shot in the dark, however maybe someone had a similar issue. Some console apps are being invoked by either SQL Server 2008, or Autosys (job schedule) under Windows Server 2008; output results of execution are being saved into .txt files. Every so often, with no definite pattern as far as I can tell saved output is displayed as a series of what I presume are Chinese characters. Have anyone encountered phenomenon above?

• Vim navigation clunkiness

  - by Sean Chambers

  I've committed myself to diving into vim to become faster at writing code for ruby/python and I'm having a hard time navigating around files. Mainly, I'm referring to switching between insert mode and navigation modes. Maybe I'm just not completely used to the editor yet but it feels very awkward to constantly be switching in and out of insert mode. Is this something that will go away with time? Are there any tricks to getting quicker at moving in and out of insert mode?

• How does timezone really work in relation to PHP and MYSQL?

  - by Rick

  I am getting very strange results in terms of timezones. I am currently using Wordpress and everytime I register a new user, I see the wrong datetime in the database. Ok so I am suspecting it is picking up the server time. So then I then set in php.ini to have date.timezone = "America/Los_Angeles" but again the time is still not correct in the database...And yes I have also set the timezone in Wordpress correctly. So how can this be done?

• How can I set a default sort for tables in PHPMyAdmin (i.e. always "Primary key - Descending")

  - by jeremyclarke

  Even though its obnoxious in a lot of ways I use PHPMyAdmin all the time to debug database issues while writing PHP. By default it sorts tables by primary key ascending. 99% of the time I would rather have the newest data (my test data) shown at the top by default rather than the useless first few records ever saved. Is there a way to configure PHPMyAdmin to show the newest records by default? To alter similar behavior?

• How much memory is my iphone app using (from Simulator)

  - by Jonathan

  I know this has something to do with Instruments, but well it's kind of confusing and searching for Instruments on Google doesn't help much. I'd like to know how well my app runs, like how much memory it uses. I just don't know where to find something like: "As close as we can tell from the simulator you'll app will currently be using xx MBs of RAM on a real iphone device." I need help on how to get this information.

• How to resize an image smoothly (with resampling) using Windows API calls?

  - by Clay Nichols

  I need to resize images and resample them so they don't end up all jagged (I think that's called aliasing). I found some code (sorry, lost the link) that does this in pure VB6 code but it's a bit slow (2-5 seconds) and I'm displaying pictures in real time so I need something faster. I seem to recall seeing some examples of doing this with the GDI+ library. An example in VB6 would be ideal, but I can probably work with a simple example with Windows API calls in another language.

• URL redirection if wrong url

  - by xRobot

  I have this method in my book model: def get_absolute_url(self): return "/book/%s/%s/%i/%i/" % ( self.book_title, self.book_editor, self.book_pages, self.id) So the urls of each book are like this: example.com/book/the-bible/gesu-crist/938/12/ I want that if there is an error in the url, then I get redirected to the real url by using book.id in the end of the url. For example if I go to: example.com/book/A-bible/gesu-crist/938/12/ the I will get redirected to: example.com/book/the-bible/gesu-crist/938/12/ How can I do that ?

• IE 8 install how to get version 8.0.6001.18702

  - by Robin

  I am having trouble installing the latest version of IE namely version 8.0.6001.18702. I downloaded the install from Microsoft but when the install is completed, the version number is reported as IE 8.0.6001.18702IC. This version does not work on all web applications and I need to get the correct final version installed. The problem is compounded by the installation downloading any updates from the Microsoft site so that there is no real control over the final version you get. Any ideas?

• Windows Server 2008 Alerting to Low memory

  - by t1nt1n

  I have a file and print server running on Windows 2008 R2 fully patched in a VSphere environment (ESXi 5.1 fully updated). Every evening between 19:20 and 19:30 our monitoring software reported that the available memory is 1% and performance is dire. There is nothing in the event logs to point to an issue. At this point in the evening I am general the only user on the system to check to see why these alerts are going off. Things I have done; Checked to see if any backups are running – None at all. Checked Scheduled tasks – None before or during this time period. Moved the VM to another host. AV is disabled to rule out that as the issue. The server does not have any problems during the day with memory when fully loaded with about 50 users. The server did have 4GB ram provisioned but I have increased this to 5Gb. Running PrefMon at the time (I will save the graphs tonight) There very little CPU usage at the time but RAM usage goes up.

• which is better in general, map or vector in c++?

  - by tsubasa

  As I know that accessing an element in vector takes constant time while in map takes logarithmic time. However, storing a map takes less memory than storing a vector. Therefore, I want to ask which one is better in general? I'm considering using one of those two in my program, which has about 1000 elements. I plan to use 3 dimensional vector, which would take 1000x1000x1000 elements.

• Specific position for tooltip

  - by Fiona

  Hello, I have a layer which opens up as a tooltip everytime I hover a button. I simply did that by creating a JS function which displays or hides the layer. Now, I am not a pro in JavaScript. My problem is the following: when the button is scrolled towards the top oft he screen I want the tooltip opening below – and if the button is near the bottom of the screen I want the tooltip opening above. Right now I just did it with absolute positioning. But obviously that doesnt do the trick. Who can help? Thanks!

• How do you DELETE rows in a mysql table that have a field IN the results of another query?

  - by user354825

  here's what the statement looks like: DELETE FROM videoswatched vw2 WHERE vw2.userID IN ( SELECT vw.userID FROM videoswatched vw JOIN users u ON vw.userID=u.userID WHERE u.companyID = 1000 GROUP BY userID ) that looks decent to me, and the SELECT statement works on its own (producing rows with a single column 'userID'. basically, i want to delete entries in the 'videoswatched' table where the userID in the videoswatched entry, after joining to the users table, is found to have companyID=1000. how can i do this without getting the error in my sql syntax? it says the error is near: vw2 WHERE vw2.userID IN ( SELECT vw.userID FROM videoswatched vw JOIN users u and on line 1. thanks!

• Is the Google Annotations Gallery useful in production code?

  - by cafe

  I could actually see a use for the Google Annotations Gallery in real code: Stumble across code that somehow works beyond all reason? Life's short. Mark it with @Magic and move on: @Magic public static int negate(int n) { return new Byte((byte) 0xFF).hashCode() / (int) (short) '\uFFFF' * ~0 * Character.digit ('0', 0) * n * (Integer.MAX_VALUE * 2 + 1) / (Byte.MIN_VALUE >> 7) * (~1 | 1); } This is a serious question. Could this be used in an actual code review?
