• How to avoid Hotmail/Live rejections for (legit) large volume eMailing?

  - by vmarquez

  While qualifying eMail for Spam, Hotmail/Live checks the historical records of numbers of eMails sent by a sender (FROM, eMail Server, IP, etc.). Some times, perfectly valid bulk eMails that are not Spam, (i.e. double opt-in list, from a server with proper SPF Record, signed with DKIM, unregister links and contact info, etc.) are rejected and not delivered to destinataries. Not even to their Junk folder. I guess we can avoid this situation by progressivelly "training" Hotmail/Live about the reputation of our sender and sending small quantyties of eMails innitially and increasing the quantity for some amount/percentaje during each delivery. Are there guidelines or do you have any experience on these quantities, strategy, solutions? Thank you in advance. EDIT: This question with a bounty is still unanswered. 8 hours to be automatically awarded! Do you have the answer?

• When using membership provider, do you use the user ID or the username?

  - by Chris

  I've come across this is in a couple of different applications that I've worked on. They all used the ASP.NET Membership Provider for user accounts and controlling access to certain areas, but when we've gotten down into the code I've noticed that in one we're passing around the string based user name, like "Ralph Waters", or we're passing around the Guid based user ID from the membership table. Now both seem to work. You can make methods which get by username, or get by user ID, but both have felt somewhat "funny". When you pass a string like "Ralph Waters" you're passing essentially two separate words that make up a unique identifier. And with a Guid, you're passing around a string/number combination which can be cast and made unique. So my question is this; when using Membership Provider, which do you use, the username or the user ID to get back to the user? Thanks all!

• Imitating Exchange Server's "RBAC AuthZ" in my own application... (is there something similar?)

  - by makerofthings7

  Exchange 2010 has a delegation model where groups of winrm cmdlets are essentally grouped into roles, and the roles assigned to a user. (Image source) This is a great & flexible model considering how I can leverage all the benefits of PowerShell, while using the right low level technologies (WCF, SOAP etc), and requiring no additional software on the client side. (Image source) Question(s) Is there a way for me to leverage Exchange's delegation model in my .NET application? Has anyone attempted to imitate this model? If I must start from scratch, how would I go about imitating this approach?

• Calculate an AABB for bone animated model

  - by Byte56

  I have a model that has its initial bounding box calculated by finding the maximum and minimum on the x, y and z axes. Producing a correct result like so: The vertices are then stored in a VBO and only altered with matrices for rotation and bone animation. Currently the bounds are not updated when the model is altered. So the animated and rotated model has bounds like so: (Maybe it's hard to tell, but the bounds are the same as before, and don't accurately represent the rotated/animated model) So my question is, how can I calculate the bounding box using the armature matrices and rotation/translation matrices for each model? Keep in mind the modified vertex data is not available because those calculations are performed on the GPU in the shader. The end result I want is to have an accurate AABB the represents the animated model for picking/basic collision checks.

• Changing email application in Preferred Applications to GMail?

  - by grm

  I'm trying to change the Preferred Application for email. I have installed the package desktop-webmail, but there is no new option under System - Preferences - Preferred Application as you would expect, infact, there is only one option there, only Evolution. According to this post it should be possible to set a custom application, but no option is available. Is it possible to setup GMail as Preferred email app so that File - Send by email works in gnome apps? This seems to be a dup of another post here, Thing is that this works fine in 10.10, but in 11.04 this method no longer work. My post above is meant for 11.04 and the question is still valid.

• Multiple values for a specif custom variable in Google Analytics

  - by Nicola Pacini

  we're trying to get rid of a this question : would it be possible to setup more than one value in a custom variable in Google Analytics, at page level ? Eg: _gaq.push(['_setCustomVar',3,'Tag','Custom Variables',3]); We'd like to track most popular tags on a web site who publishes news, articles and stuff. Contents are categorized (each content belongs to one category) and tagged (1 or more tags for each article). So, we'd like to apply this code: _gaq.push(['_setCustomVar',3,'Tag','Custom Variables',3]); _gaq.push(['_setCustomVar',3,'Tag','Google Analytics',3]); in a page that shows an article with these two tags assigned. What do you think? Honestly I didn't find anything in documentation from Google and some other example sites. Many thanks! Nicola

• Google webmaster tools / Geographic location settings

  - by JochemTheSchoolKid

  I am building an website. It has an .nl domain. Now only my domain is showing up on google.nl I hope I can change this somehow that it could be findable in all google's (like google.com / co.uk) and so on. If I look on google forums. They say go to webmaster tools and change your geographic position over there. But I have added this site and I am not able to change it there because there is no select box. I dont have any idea were to search (yes I searched on google offcourse) or where to ask for this special problem. So maybe here can someone redirect me or explain me what is possible and what not. The question is can I make an .nl domain findable in (almost) all google search sites? And so on how can I do that. Picture of my google webmaster tools (nl): http://i.stack.imgur.com/ZuP4L.png

• Ubuntu has LTS and normal version now. Does Lubuntu have the same?

  - by Elysium

  I am wondering if this is the right place for this question, but if not...then the moderators will surely tell me so. Anyway....there is Ubuntu 12.04 LTS and the normal 12.10 version. Is that the same with Lubuntu? On their site, for some reason, they seem to be promoting the 12.10 version while for me an LTS is always more appealing. I am wondering if they have the same ideology as the Ubuntu team. UPDATE: Is it okay to talk about Lubuntu here at all? I understand that it is a flavour of Ubuntu...but still. Are they 2 very different teams?

• How to convince management to deal with technical debt?

  - by Desolate Planet

  This is a question that I often ask myself when working with developers. I've worked at four companies so far, and I've noticed a lack of attention to keeping code clean and dealing with technical debt that hinders future progress in a software app. For example, the first company I worked for had written a database from scratch rather than take something like MySQL and that created hell for the team when refacoring or extending the app. I've always tried to be honest and clear with my manager when he discusses projections, but management doesn't seem interested in fixing what's already there and it's horrible to see the impact it has on team morale and in their attitude towards others. What are your thoughts on the best way to tackle this problem? What I've seen is people packing up and leaving and the company becomes a revolving door with developers coming and and out and making the code worse. How do you communicate this to management to get them interested in sorting out technical debt?

• implementing match-making & community system for multiplayer games

  - by kamziro

  These days, games often have multiplayer portals with chat channels & match making system for the multiplayer aspects of the game. An example would be battle.net, magic the gathering online's chat rooms, halo etc. Now, for the rest of us indie gamers that probably won't be able to spend much development effort on creating those back-ends from scratch, what options do we have? I was thinking of something along the line of using IRC as the backbone of the system. From there, the "community" aspect and implement player tracking, game tracking and match making on top of that. It seems to be what the old battle.net (brood war era) used to be. The question is, is this easy to do? What does it take to run an irc server, and I suppose this also requires writing an IRC client (which seems to have been done a lot these days?)? If there are other ways as well (say, an open framework for this stuff), let's hear them too.

• How to fill certain application design learning "gaps"?

  - by e4rthdog

  In life it doesnt matter if you do one thing for 15 years. You will end up waking one day and asking stuff that are equal to "how do i walk?" :) My specific question is that as a new entrant to C# and OOP i am stepping into many little "details" that need to be addressed. Written a lot of code in VB.NET / cobol / simple php e.t.c surely does not help much into the OOP world... So , even after reading entry level books for C# and watching some videos i recently found out about the "factory model design" for applications. I would appreciate if any of you guys recomment some reading on application design architecture for further reading...

• Scripting with variables from file

  - by Nooster

  I have several videos on my PC that I would like to shorten. For instance I have a 30 sec video where I want to have the section from sec 15 to 20 (a 5sec video). To cut this, I use avconv. avconv -i input.mp4 -ss 15 -acodec copy -vcodec copy -t 5 output.mp4 This command works pretty well. I have many videos I want to cut the same way. This is why I created a textfile containing the information: input-name, start of cut, length of cut, output-name. Those are written into in.txt that looks like this: input.mp4 15 5 output.mp4 input1.mp4 32 10 output1.mp4 input2.mp4 10 7 output2.mp4 ... My question is: How do I have to modify the avconv-command to cut my videos automatically? What I tried was this, but it didn't work at all: avconv -i $1 -ss $2 -acodec copy -vcodec copy -t $3 $4 < in.txt Any idea?

• Anisotropic and trilinear filtering?

  - by fedab

  I'm confused about the usage of trilinear filtering and anisotropic filtering in SharpDX. As far as i understood, trilinear filtering does linear filtering to the textures and in a case of LOD-change it also interpolates between the too LODs to smooth the transition. Anisotropic filtering make the texture bigger. Now it is possible to use trilinear filtering to do the same thing, due to anisotropic filtering with bigger textures. This causes a lesser blurred image, when you use anisotropy, because the interpolation is better. Now, it should be possible to use trilinear filtering and anisotropic filtering at the same time. But in the SamplerState i can only choose Filter.Anisotropy or Filter.MinMagMipLinear (should be trilinear, right?). You can see all possible filters here: D3D11 Filter Enumeration. So my question: Can you use both techniques together, if yes, how can i archieve that in SharpDX with SamplerState?

• DBMS agnostic - What to name the COUNT column from a SQL Query

  - by cyberkiwi

  I have trouble naming the COUNT() column from SQL queries and will swap between various variants _Count [Count] (sql, or "count" or backticks for MySQL etc) C Cnt CountSomething (where "something" is the field being counted, or "CountAll") NoOfRows RowCount etc Has anyone come up with any name that you are happy with and always use without hesitation? This is bothering me because after joining SO just recently, my answers have shown this tendency of flip-flopping with no consistency. I need to get this sorted. Please help. (While we're at it, what do you use for SUM etc?) Note: Before you close this question, consider that this one was not: What's the best name for a non-mutating “add” method on an immutable collection?

• matrix 4x4 position data

  - by freefallr

  I understand that a 4x4 matrix holds rotation and position data. The rotation data is held in the 3x3 sub-matrix at the top left of the matrix. The position data is held in the last column of the matrix. e.g. glm::vec3 vParentPos( mParent[3][0], mParent[3][1], mParent[3][2] ); My question is - am I accessing the parent matrix correctly in the example above? I know that opengl uses a different matrix ordering that directx, (row order instead of column order or something), so, should the mParent be accessed as follows instead? glm::vec3 vParentPos( mParent[0][3], mParent[1][3], mParent[2][3] ); thanks!

• How do I get an Acer Aspire One D270 working?

  - by ronnie

  I was planning to buy Acer Aspire One D270 within a few days and as everybody installs linux on their netbook I was also planning to do that. Now, my question is how is Acer's hardware compatibility with linux and specifically in respect to the new Acer Aspire One D270. Has anybody tried installing linux on these new netbooks. It will be a great help if a D270 user can share his/her experience with linux usage. I read on some forums that there is some linux driver issue with Intel GMA 3600 and that people are not able to adjust their brightness. So, as I am a linux noob is this a major issue or not. Specs: RAM : 2Gb DDR3 Processor: Intel N2600(Cedar Trail) Graphics: Intel GMA 3600 HardDisk: 320Gb 5400 rpm

• What does "context-free" mean in the term "context-free grammar"?

  - by rick

  Given the amount of material that tries to explain what a context-free grammar (CFG) is, I found it surprising that very few (in my sample, less than 1 in 20) give an explanation on why such grammars are called "context-free". And, to my mind, none succeeds in doing so. My question is, why are context-free grammars called context-free? What is "the context"? I had an intuition that the context could be other language constructs surrounding the currently analyzed construct, but that seems not to be the case. Could anyone provide a precise explanation?

• How do you update copyright notices?

  - by James

  So now it's 2011, and as I carry on coding on our active projects it's time to update some copyright notices. eg. Copyright Widgets Ltd 2010 to Copyright Widgets Ltd 2010, 2011 My question is when do you update the copyright notices? Do you change the notice in the head of a file the first time you work on that file? Since a module is one piece of code consisting of many files that work together, do you update all notices in that module when you change a single file in that module? Since a program is one piece of code (maybe consisting of many modules), do you update all notices in that program when you change a single file in that program? Or do you just go through and change en-mass over your morning coffee on the grounds your about to start programming and updateing things?

• Ensure we're found in Facebook search for both full & abbreviated company names?

  - by hawbsl

  We have a client with a facebook page, let's say his company is called Bob Roberts Super Widgets. And if you search in Facebook for Bob Roberts Super Widgets then up he pops. But the shorthand he's commonly known by is BR Super Widgets and indeed the website we've created for him is br-super-widgets.com. In Facebook, searching for BR Super Widgets doesn't show up our Mr Bob. We don't have a lot of Facebook expertise, so asking for help here. Does anyone know how to ensure you're found in Facebook search for both short and long company names? Have found this this similar question in the Facebook forum but the poor old questioner never got a response.

• Should testers approve releases, or just report on tests?

  - by Ernest Friedman-Hill

  Does it make sense to give signoff authority to testers? Should a test team Just test features, issues, etc, and simply report on a pass/fail basis, leaving it up to others to act on those results, or Have authority to hold up releases themselves based on those results? In other words, should testers be required to actually sign off on releases? The testing team I'm working with feels that they do, and we're having an issue with this because of "testing scope creep" -- the refusal to approve releases is sometimes based on issues explicitly not addressed by the release in question.

• Serverside memory efficiency and threading for a turn based game

  - by SkeletorFromEterenia

  Im programming on a turn based war-game for some years now (along with the engine) and Im having quite a hard time at figuring out what the games server architecture should look like, since most game server architecture articles I found focus either on FPS oder MMOGs, which doesn't really fit since I want many matches with 1- 16 players on my server, with each match being played in turn based mode. My chief concern is memory usage, since the most basic approach of loading every game that is being played completely into RAM should be quite inefficient, so is there a suitable strategy for selecting only the needed bits and loading them? Another question I got is how to design the threading on the server, since I think using only a single thread could be a problem due to the fact that the game or part of it might have to be loaded from the database. I would be very happy if you could share your knowledge or point me to material on this topic.

• How To Specify Bitrate, Codec and Demultiplexing for VLC Video Capture or Recording

  - by Subhash

  I capture video from old TV tuner card - Pinnacle PCTV - using VLC. The video is from the Composite input and audio is from I guess the mixer or Line in. The command I use is: vlc v4l2:///dev/video0:normal=pal:width=720:height=576:input=1 :input-slave="alsa://hw:0,0" In VLC, I have enabled the Advanced Controls toolbar, which allows me to record videos when I want to. However, these videos are uncompressed - very big and play only with VLC. Totem throws the "Could not demultiplex stream" error. I need to convert them using WinFF to reduce their size and make them playable with Totem and other software. My question is whether I can configure the recording settings - the codecs and the bitrate, and also get the stream demultiplexed. If I pass any -sout parameter with command I get a "Segmentation fault". I use 64-bit Ubuntu 10.10.

• SQL SERVER – Detect Virtual Log Files (VLF) in LDF

  - by pinaldave

  In one of the recent training engagements, I was asked if it true that there are multiple small log files in the large log file (LDF). I found this question very interesting as the answer is yes. Multiple small Virtual Log Files commonly known as VLFs together make an LDF file. The writing of the VLF is sequential and resulting in the writing of the LDF file is sequential as well. This leads to another talk that one does not need more than one log file in most cases. However, in short, you can use following DBCC command to know how many Virtual Log Files or VLFs are present in your log file. DBCC LOGINFO You can find the result of above query to something as displayed in following image. You can see the column which is marked as 2 which means it is active VLF and the one with 0 which is inactive VLF.
