• T-SQL Tuesday #15 : Running T-SQL workloads remotely on multiple servers

  - by AaronBertrand

  This month's installment of T-SQL Tuesday is hosted by Pat Wright ( blog | twitter ). Pat says: "So the topic I have chosen for this month is Automation! It can be Automation with T-SQL or with Powershell or a mix of both. Give us your best tips/tricks and ideas for making our lives easier through Automation." In a recent project, we've had a need to run concurrent workloads on as many as 100 instances of SQL Server in a test environment. A goal, obviously, is to accomplish this without having to...(read more)

• Is it possible for a good programmer to have never used version control?

  - by lortabac

  I am looking for an expert programmer to help solve a difficult situation. The interviews so far have been surprisingly disappointing. The best candidate so far is a very experienced programmer who has never used version control software. The problem in itself might not be too serious because it is something which can be learned in a short time. But there is a deeper aspect, which worries me: How is it possible to actively develop software for 10-15 years without ever needing version control? Is the fact itself of not looking for a solution to the problem of tracking changes a sign of a wrong attitude to programming?

• Microsoft Build 1st Day

  - by Dave Noderer

  Great keynote and I don’t like keynotes.. Seeing the great breadth of large and small devices and the number of manufacturers along with the software vision for Windows 8 and Windows Phone 8 was inspiring. Jordan Rudess demonstrates Tachyon on Windows 8 Then he played for a while too..   I especially liked Steve Balmers 82” slate!! Can I have one!   And best of all, they finally released the Windows Phone 8 SDK. http://www.microsoft.com/en-us/download/details.aspx?id=35471 Off to sessions…   Stay tuned for more!

• What parameters to use to compare GUI frameworks / toolkits?

  - by gooli

  I'm doing some research on the best GUI toolkit to use for future products at the company. We're talking about a fairly large organizations with quite a bit of code and a complete rewrite project in planning. Don't ask. Anyway, I'm trying to create a list relevant parameters to judge the toolkits. What would you use to drive the comparison? Here's what I've got so far: Maturity Ease of development Ease of prototyping Ease of maintenance Size of hiring pool Available knowledge at the company Training costs Community size Community level of expertise (how hard to find good answers to complex problems) Amount of expert-level books available Ability to interface to other technologies Deployment considerations Visual aesthetics Ability to access OS resources Multiple monitor support (something that might come in handy in our particular application)

• Component based design, but components rely on eatchother

  - by MintyAnt

  I've begun stabbing at a "Component Based" game system. Basically, each entity holds a list of components to update (and render) I inherit the "Component" class and break each game system into it. Examples: RenderComponent - Draws the entity MovementComponent - Moves the entity, deals with velocity and speed checks DamageComponent - Deals with how/if the entity gets damaged... So. My system has this: MovementComponent InputComponent Now maybe my design is off, but the InputComponent should say things like if (w key is down) add y speed to movement if (x key is down) Trigger primary attack This means that the InputComponent sort of relies on these other components. I have to do something alone the lines of: if (w key is down) { MovementComponent* entityMovement = mEntity->GetMovement(); if (entityMovement != NULL) add y speed to movement } which seems kinda crappy every update. Other options? Better design? Is this the best way? Thanks!

• Unit testing a text index

  - by jplot

  Consider a text index such as a suffix tree or a suffix array supporting Count queries (number of occurrences of a pattern) and Locate queries (the positions of all the occurrences of a pattern) over a given text. How would you go about unit testing such a class ? What I have in mind is to generate a big random string then extract a random substring from this big string and compare the results of both queries with naive implementations (such as string::find). Another idea I have is to find the most frequent substring of length l appearing in the original string (using perhaps a naive method) and use these substrings for testing the index. This isn't the best way, so what would be a good design of the unit tests for a text index ? In case it matters, this is in C++ using google test.

  - by sam

  When writing a guest blog for a site and in the blog post i write i link back to my self, that counts as an imbound link. Writing something on my blog, like "have a look at this post i wrote for _" made that a link the links would be recipricle, correct ? thus cancling each other out.. If i was to to make the link back to my article a nofollow link then would i still get the link juice ? If i write guest blog post and the site want to also write a guest blog on my site later on whats the best way to handle it as wont these both cancel each other out and have no effect ?

• Mounting filesystem with special user id set

  - by qbi

  I want to mount the device /dev/sda3 to the directory /foo/bar/baz. After mounting the directory should have the uid of user johndoe. So I did: sudo -u johndoe mkdir /foo/bar/baz stat -c %U /foo/bar/baz johndoe and added the following line to my /etc/fstab: /dev/sda3 /foo/bar/baz ext4 noexec,noatime,auto,owner,nodev,nosuid,user 0 1 When I do now sudo -u johndoe mount /dev/sda3 the command stat -c %U /foo/bar/baz results in root rather than johndoe. What is the best way to mount this ext4-filesystem with uid johndoe set?

• How should my local git workflow work?

  - by Anonymous -

  At home, I have a server that is running some software (on a LAMP stack, but only accessible internally). I have another machine and a laptop that I both use for developing said software. What is the best workflow for me? Should I have a repository on my local server, create a live branch, staging branch and development branch, then checkout the development branch from my laptop/development PC to work on, commit that back when I'm done, then merge the development branch with the staging branch for testing, before further merging to the live branch? Would I simply checkout the production branch to my /www/var/ on my server? Or am I thinking/going about this all wrong? Thanks.

• In regards to applet games and UDP

  - by Tom Steinberg

  I've got about a year in Java experience, and would like to set up a server and client for an applet game. However, there doesn't appear to be any tutorials out there on anything like I want to use. I would the server to be able to store an array of x and y coordinates with a player name somehow associated to them, and send them to multiple clients in a short time span. I would like the client implemented in the applet, and be able to request any player's position data. I'd like to use UDP, because it seems to be the best option for efficient (if less reliable) transmission of data. If anyone could give me some pointers on how to do such a project, or point me to an appropriate tutorial, I'd certainly appreciate it.

• I have a library and several small programs that use it: how should I structure my git repositories?

  - by Dan

  I have some code that uses a library that I and others frequently modify (usually only by adding functions and methods). We each keep a local fork of the library for our own use. I also have a lot of small "driver" programs (~100 lines) that use the library and are used exclusively by me. Currently, I have both the driver programs and the library in the same repository, because I frequently make changes to both that are logically connected (adding a function to the library and then calling it). I'd like to merge my fork of the library with my co-workers' forks, but I don't want the driver programs to be part of the merged library. What's the best way to organize the git repositories for a large, shared library that needs to be merged frequently and a number of small programs that have changes that are connected to changes in the library?

• Which parallel pattern to use?

  - by Wim Van Houts

  I need to write a server application that fetches mails from different mail servers/mailboxes and then needs to process/analyze these mails. Traditionally, I would do this multi-threaded, launching a thread for fetching mails (or maybe one per mailbox) and then process the mails. We are moving more and more to servers where we have 8+ cores, so I would like to make use of these cores as much as possible (and not use 1 at 100% and leave the seven others untouched). So conceptually, as an example, it would be nice that I could write the application in such a way that two cores are "continuously" fetching emails and four cores are "continuously" processing/analyzing the emails (since processing and analyzing mails is more CPU intensive than fetching mails). This seems like a good concept, but after studying some parallel patterns, I'm not really sure how this is best implemented. None of the patterns really fit. I'm working in VS2012, native C++, but I guess from a design point of view this does not really matter and just some pointers on how to organize this would be great!

• How to apply a filter to the screen of a running program?

  - by Shahbaz

  The idea is to take old games without modifying them, but have the graphics card apply a series of filters to their output before sending them to the monitor. A very crude example would be to take a game that has a resolution of 640x480 and do: Increase the resolution to 1280x960 Apply a blur (low pass filter) Apply a sharpen (1 + high pass filter) These steps may not necessarily be the best to improve the visuals of an old game, but there are a lot of techniques that are well-known in image processing for this purpose. The question is, do the (NVidia) graphics cards give the ability to load a program that modifies the screen before sending it to the monitor? If so, how are they called and what terminology should I use to search? I would be comfortable with doing the programming myself if this ability is part of a library. Also, would the solution be different between Windows and Linux? If so, either is fine, since most of the games are probably runnable by wine.

• building a website

  - by Ant

  A couple of my friends run a business and they asked me to build them a public website. It will only be used for information about the company with soe pictures. No transactions will be involved. Right now I work for a company where I build internal websites, and do alot of backend programming in C#. I understand html, css, jquery, etc. so I feel like I am completely capable of building a website for them. However, I do not know all the basic knowledge to building one. For example, where should we host the files, what type of security issues do I need to be aware of, what's the best software to use for developing websites (I use visual studio at work), where can I find some design techniques, etc. Any help is appreciated.

• Programming my first C++ program

  - by Jason H.

  I have a basic understanding of programming and I currently learning C++. I'm in the beginning phases of building my own CLI program for ubuntu. However, I have hit a few snags and I was wondering if I could get some clarification. The program I am working on is called "sat" and will be available via command line only. I have the main.cpp. However, my real question is more of a "best practices" for programming/organization. When my program "sat" is invoked I want it to take additional arguments. Here is an example: > sat task subtask I'm not sure if the task should be in its own task.cpp file for better organization or if it should be a function in the main.cpp? If the task should be in its own file how do you accept arguments in the main.cpp file and reference the other file? Any thoughts on which method is preferred and reference material to backup the reasoning?

• Good practices when writing a parser for a standard file format (such as ePub)

  - by J-F L-R

  I am considering writing an Android reader software that can read ePubs and display them. I checked the ePub standard documents. However, these contain a lot of information. So I am wondering what is the process of implementing a standard for a file format. What are the steps to get a working implementation without passing by parts of the standard? Are there any best practices? Also, is it even possible to program this alone in a reasonable time? From what I have already found out, ePub is basically a zip archive. That means I could probably use zlib to decompress it. The content is in XHTML and CSS, so I believe it should be possible to display it in a WebView. The parts that are missing are writing the code that can read the metadata and manage the non-standard XHTML extensions.

• What tags should be used for SEO in simple blog posts? [closed]

  - by homepage

  Possible Duplicate: What are the best ways to increase your site's position in Google? Order of HTML meta tags I'm new to websites in general (which is why I'm starting on blogger) and am just curious as to which tags I should be using in my posts? My posts generally include a title relevant to the keyword of my blog, an image, a video, my content, and a link to my twitter. I don't really use any tags and someone mentioned that they may help for SEO. So I figured I would ask for some advice from people who know what they are doing. EDIT I apologize for not clarifying, I meant tags such as: Header tag: <h1>This is my title</h1> Image tags with attributes: <img src="keyword_image.jpg" width="100" height="78" ALT="this_shows_examples"> What other tags and attributes are ones I should use for a well put together website and SEO?

• How to properly shield a Product Owner from outside?

  - by xsAce

  Update: We are a very small team (3 people) and thus I (Scrum Master) and the Product Owner are also developers doing some coding. We are aware of this situation and we are actively trying to recruit some new talents. But it's hard! Meanwhile... we need to adapt... so my question: The Product Owner complains about having too much outside noise (mainly stakeholders feature requests), and he can't focus on the sprint realisation. We agree that we should try to educate people on our process implications (sprint durations and product backlog), to reduce the noise. But as a Scrum Master, how am I supposed to shield a PO from outside? Isn't he supposed to be in contact with the management and business? Also, if people outside don't want to waste too much time learning agile, what is the best way to educate them?

  Monday May 10th, 2010 represents my largest and best event to-date, that I have ever hosted. For the last seven years, I’ve grown a technical audience around Microsoft programming / developers in the Phoenix area. Some travel from California, New Mexico, and other parts of Arizona, but for the most part the crowd is local. In years past, this all day event has been as small as 300 folks, and as large as 500, and I’ve tried been to venues around the valley some better than others. This...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.
