• Two bugs you should be aware of

  - by AaronBertrand

  In the past 24 hours I have come across two bugs that can be quite problematic in certain environments. LPIM issue with SetFileIoOverlappedRange Last night the CSS team posted a blog entry detailing a potential issue with Lock Pages in Memory and Windows' SetFileIoOverlappedRange API. I tweeted about it at the time, but thought it could use a little more treatment. The potential symptoms can vary, but include the following (as quoted from the blog post): Wide ranging in SQL from invalid write location,...(read more)

• Why am I having so many problems installing Ubuntu 13.10 alongside Vista?

  - by Matt Gazaway

  I am trying to setup my laptop to dual boot Ubuntu 13.10 and Windows Vista. I get as far as the drive table and it either freezes up or I get an error saying "unable to satisfy partition parameters" or something very similar. Now I just have a black screen with alternating indications that a request for cache data failed and something to do with a "write through". Any ideas on what I might be doing wrong?

• PHP Drupal alternatives

  - by Quinma

  Based off answers to this question: Will I pick bad coding habits from PHP books? and many others it is a general consensus that PHP is not the most well suited language for web development anymore (if you are not completely knowledgeable about the language). I use Drupal and write custom modules in PHP, does this viewpoint of PHP being an ill fitted web coding language also apply to Drupal based PHP sites? I generally build community sites and intra-company sites, are there better means of building these than with PHP and drupal frameworks?

• Calculate pi to an accuracy of 5 decimal places?

  - by pgras

  In this message at point 18 I saw following programming question: Given that Pi can be estimated using the function 4 * (1 – 1/3 + 1/5 – 1/7 + …) with more terms giving greater accuracy, write a function that calculates Pi to an accuracy of 5 decimal places. So I know how to implement the given function and how to choose how "far" I should calculate, but how can I tell when I've reached the "accuracy of 5 decimal places" ?

• Where in the filesystem should I store shared data?

  - by misterben

  Where in the unix filesystem is the conventional location to save non-user specific data, for example data shared via nfs or ftp, or backups? I could obviously create and use any arbitrary folder (such as /home/shared, /data or /var/data), but I'm really wondering if there are any "best" or "common" practice guidelines. The Filesystem Hierarchy Standard doesn't specify a location for shared data. For backups, I tend to use /var/backups, but as several cronjobs write to it should it really be left for their use?

• Why has the accessor methods from the JavaBean specification become the standard for Java development?

  - by Dakotah North

  The JavaBeans Specification describes a JavaBean as A Java Bean is a reusable software component that can be manipulated visually in a builder tool Since the majority of the lines of code that are written seem to have nothing to do with being manipulated visually in a builder tool, why has the JavaBean specification been the "way" to write object oriented code? I would like to forgo the traditional getter/setter in favor of Fluent Interfaces all throughout the code, not just in builders but fear doing so since this is traditionally not the way way object oriented code is written in Java.

• How can I deal with the cargo-cult programming attitude?

  - by Aivar

  I have some computer science students in a compulsory introductory programming course who see programming language as a set of magic spells, which must be cast in order to achieve some effect (instead of seeing it as a flexible medium for expressing their idea of solution). They tend to copy-paste code from previous, similar-looking assignments without considering the essence of the problem. Can anyone recommend some exercises or analogies to make these students more confident that they can, and should, understand the structure and meaning of each piece of code they write?

• Why my MainWindow doesn't get he focus?

  - by Roberto

  window = self.builder.get_object("main-window") print window.get_focus() print window.has_focus() print window.is_active() print window.has_toplevel_focus() Terminal output: <MainWindow object at 0x28c26e0 (Mainwindow at 0x26a1210)> False False False So I got the right answer on get_focus(), but when I ask is MainWindows has the focus, it is return with False. Why? I don't understand it. I would like to write a method to focus_changed, but I can't if it doesn't works.

• Connect a method for window destroy

  - by Roberto

  I have a main window with a Gtk Button named openDialog. If I click on this button another Window (addName) popups. I would like to write a method (or a function, don't know which is the right name in python) in my main window file, called printHi. I would like to run this printHi method (in my main window file), when addName window is destroyed. I tried something like this: def on_addName_destroy(): printHi() But it doesn't work. Any suggestion?

• Reporting what's not there

  It's easy to write queries that will show data in the database that matches a criteria. However, if no data in the database matches the criteria, it becomes more difficult. This article examines two different scenarios where it's necessary to create data in order to be able to report zero values in queries.

• In C and C++, what methods can prevent accidental use of the assignment(=) where equivalence(==) is needed?

  - by DeveloperDon

  In C and C++, it is very easy to write the following code with a serious error. char responseChar = getchar(); int confirmExit = 'y' == tolower(responseChar); if (confirmExit = 1) { exit(0); } The error is that the if statement should have been: if (confirmExit == 1) As coded, it will exit every time, because the assignment of the confirmExit variable occurs, then confirmExit is used as the result of the expression. Are there good ways to prevent this kind of error?

• Building a Store Locator ASP.NET Application Using Google Maps API

  The past couple of projects I've been working on have included the use of the Google Maps API and geocoding service in websites for various reasons. I decided to tie together some of the lessons learned, build an ASP.NETstore locator demo, and write about it on 4Guys. Last week I published the first article in what I think will be a three-part series: Building a Store Locator ASP.NET Application Using Google Maps (Part 1). Part 1 walks through creating a demo where a user can type in an address and any stores within a (roughly) 15 mile area will be displayed in a grid.The article begins with a look at the database used to power the store locator (namely, a single table that contains one row for every location, with each location storing its store number, address, and, most important, latitude and longitude coordinates) and then turns to usingGoogle's geocoding service to translatea user-entered address into latitude and longitude coordinates. The latitude and longitude coordinates are used to find nearby stores, which are then displayed in a grid. Part 2 looks at enhancing the search results to include a map with markers indicating the position of each nearby store location. The Google Maps API, along with a bit of client-side script and server-side logic, make this actually pretty straightforward and easy to implement. Here's a screen shot of the improved store locator results. Part 3, which I plan on publishing next week, looks at how to enhance the map by using information windows to display address information when clicking a marker. Additionally, I'll show how to use custom icons for the markers so that instead of having the same marker for each nearby location the markers will be images numbered 1, 2, 3, and so on, which will correspond to a number assigned to each search result in the grid. The idea here is that by numbering the search results in the grid and the markers on the map visitors will quickly be able to see what marker corresponds to what search result. This article and demo has been a lot of fun to write and create, and I hope you enjoy reading it, too.

• On Handling Dates in SQL

  The calendar is inherently complex by the very nature of the astronomy that underlies the year, and the conflicting historical conventions. The handling of dates in TSQL is even more complex because, when SQL Server was Sybase, it was forced by the lack of prevailing standards in SQL to create its own ways of processing and formatting dates and times. Joe Celko looks forward to a future when it is possible to write standard SQL date-processing code with SQL Server.
