• Technique to Display Multiple Browser Windows Tiled at Same time?

  - by Kendor

  I have a separate monitor that I use for Toodledo (a web-based task managment app), in which I like to display various views (Next Action Status, Waiting Status, Planning Status, and Overdue Due-Date items). I've been playing around with some add-ons on Firefox that allow you to split the browser, but they are cumbersome. I'm now trying Chrome, and opening 4 different browser windows that I've tiled on the screen in quadrants (I use the Compiz grid applet for this). This is not ideal as each browser replicates the URL bar and the tab, and I don't have opening ths windows automated upon restart. Chrome is great in managing screen real estate, but this is not ideal. In Firefox I tried various extension to hide interface elements, but it was very clunky... Am wondering whether anyyone has tried to do similar with TD, and how they achieved what I'm going after? Am wondering whether someone has a good technique for accomplishing what I'm looking for?

• Using implode, explode etc.. on one line vs separating them into multiple lines with meaningful variable names

  - by zhenka

  I see a lot of people coding in PHP being rather proud if they manage to write a complicated one line statement that does clever things. But what is the advantage? It is not only harder to keep in once head while writing, but makes code much less readable. In my opinion reading short statements, if well written, can be like reading an essay, while complicated one liners can potentially make me pause and think for much longer then it would take for the coder to simply separate them into meaningful units. Am I wrong in thinking this? How would you go about proving your point to another programmer regarding this?

• How to approach scrum task burn down when tasks have multiple peoples involvement?

  - by AgileMan

  In my company, a single task can never be completed by one individual. There is going to be a separate person to QA and Code Review each task. What this means is that each individual will give their estimates, per task, as to how much time it will take to complete. The problem is, how should I approach burn down? If I aggregate the hours together, assume the following estimate: 10 hrs - Dev time 4 hrs - QA 4 hrs - Code Review. Task Estimate = 18hrs At the end of each day I ask that the task be updated with "how much time is left until it is done". However, each person generally just thinks about their part of it. Should they mark the effort remaining, and then ADD the effort estimates to that? How are you guys doing this? UPDATE To help clarify a few things, at my organization each Task within a story requires 3 people. Someone to develop the task. (do unit tests, ect...) A QA specialist to review task (they primarily do integration and regression tests) A Tech lead to do code review. I don't think there is a wrong way or a right way, but this is our way ... and that won't be changing. We work as a team to complete even the smallest level of a story whenever possible. You cannot actually test if something works until it is dev complete, and you cannot review the quality of the code either ... so the best you can do is split things up into small logical slices so that the bare minimum functionality can be tested and reviewed as early into the process as possible. My question to those that work this way would be how to burn down a "task" when they are setup this way. Unless a Task has it's own sub-tasks (which JIRA doesn't allow) ... I'm not sure the best way to accomplish tracking "what's left" on a daily basis.

• Getting the right results with bcp and DTS with multiple versions of SQL Server installed.

  - by fatherjack

  I was using SSIS for the first time on an instance the other day and came across this error when I executed a package Package migration from version 3 to version 2 failed with error 0xC001700A. The version number in the package is not valid. The version number cannot be greater than current version number. This was a pain and wasn't something that I was expecting, however, the error message made sense - the package was being executed by the wrong version of the executable. Not impossible to...(read more)

• Is it normal for programmer to work on multiple projects simultaneously.

  - by gasan

  On a current job I have 2 projects to work on. First is very huge system and the second one is smaller but it also big (first project is being developed for 12 years, second for 4 years). At first I was working only on first project and was trying to get used to it. Then I was moved to second project and tried there, so my knowledge about first project became shady. Now I have to work on both projects at the same time. It's very hard for me because despite they both use java, they use different frameworks and the amount of code and business-logic to understand is very big so I really can't hold both that projects in my head. Is it normal and I should get used to it, although my expertise became very squashy, what won't happen if I would work only on a single project? Or should I raise a concern or maybe change employer?

• Is it a bad practice to include all the enums in one file and use it in multiple classes?

  - by Bugster

  I'm an aspiring game developer, I work on occasional indie games, and for a while I've been doing something which seemed like a bad practice at first, but I really want to get an answer from some experienced programmers here. Let's say I have a file called enumList.h where I declare all the enums I want to use in my game: // enumList.h enum materials_t { WOOD, STONE, ETC }; enum entity_t { PLAYER, MONSTER }; enum map_t { 2D, 3D }; // and so on. // Tile.h #include "enumList.h" #include <vector> class tile { // stuff }; The main idea is that I declare all enums in the game in 1 file, and then import that file when I need to use a certain enum from it, rather than declaring it in the file where I need to use it. I do this because it makes things clean, I can access every enum in 1 place rather than having pages openned solely for accessing one enum. Is this a bad practice and can it affect performance in any way?

• Is it possible to have multiple subdomains point to the same Blogger blog?

  - by cclark

  For our application we want to have a status page which is hosted outside of the rest of our infrastructure so in case there are issues in our data center we can post updates for our users and our users will be able to access them. We registered a blog on Blogger and set it up with xyzstatus.blogspot.com and status.xyz.com. Everything seems to work fine. We need to perform some maintenance at our datacenter which will sever all connectivity so we're unable to have a redirect using nginx or apache. We'd like to do this with a short TTL CNAME DNS entry. Ideally www.xyz.com and app.xyz.com could be CNAMEd to status.xyz.com. When I setup the CNAME and go to that URL I get a Google broken robot 404 page. I figure I must need to let Google know it should associate traffic to www.xyz.com and app.xyz.com to the blog served up by status.xyz.com. But I can't see anywhere to do this in Blogger. Does anyone know if this is possible?

• Speeding up Connection Between Computer and Wireless/Bridged Router

  - by Justian Meyer

  Hey everyone, I looked through other questions, but didn't find useful responses. Our main computer has a dl speed of 6 Mbps, but some of our other computers are getting only 40-200 Kb! The router is wireless, but all computers are connected using a Netgear Wall-Plugged Bridge XE102, which transmits information via the building's powerline. It can't be the hardware itself, however, because some computers still manage decent speeds. The computers afflicted are running on Microsoft XP Service Packs 2 and 3, but so are computers that are totally functional. These speeds severely impede on productivity and are excruciatingly frustrating when trying to cram in time in the early hours. Could it be an issue with the computer? Location? Router? Many thanks in advance, Justian

• In OpenGl ES 2, should I allocate multiple transformation matrices?

  - by thm4ter

  In OpenGl ES 2, should I declare just one transformation matrix, and share it across all objects or should I declare a transformation matrix in each object that needs it? for clarification... something like this: public class someclass{ public static float[16] transMatrix = new float[16]; ... public static void translate(int x, int y){ //do translation here } } public class someotherclass{ ... void draw(GL10 unused){ someclass.translate(10,10); //draw } } verses something like this: public class obj1{ public static float[16] transMatrix = new float[16]; ... void draw(GL10 unused){ //translate //draw } } public class obj2{ public static float[16] transMatrix = new float[16]; ... void draw(GL10 unused){ //translate //draw } }

• How should we deal with multiple transaction-report requests?

  - by Mithir

  We are developing a system for the retail market which one of it's features will enable clients(actually consumer clubs) to go through all transactions made by end-clients. One of the ways to get this information will be via an API. The idea is that there will be requests for reports with a start date and an end date, and a response will have all the transactions between those dates. We are worry that some reports may be very large, and that some clients will repeatedly request for reports, in this case the DB and CPU will be very overloaded. The same server that will service those requests, also takes care the the actual retail transactions (received by proprietary devices) and a Web application. We are not sure about how to limit the report requests from the API so that it won't affect the system too much. So, how should we deal with this scenario? any thoughts? EDIT: just to make clear: When I mentioned proprietary devices I meant "On-Location" devices which are used during sales with end-clients, this means that these requests shouldn't get delayed, and this is the main concern.

• Can SSL Wildcards have multiple/nested levels of wildcard?

  - by Don Faulkner

  I know that an SSL wildcard certificate (*.example.org) can be used to support many names under the domain (a.example.org, b.example.org, c.example.org). I also know that the * is only good for matching a single level of name. That is, *.example.org will not work on a.b.example.org. What if I used a certificate with the name ..example.org? I'd like to build a certificate with the following name configuration: CN=example.org subjectAltName=DNS:example.org, DNS:*.example.org, DNS:*.*.example.org, DNS:*.*.*.example.org I've tried building a few like this as self-signed certificates, but I've not had good results. For example, chrome tells me "Server's certificate does not match the URL." Is it possible to have nested wildcards in a certificate, or do the popular browsers not support this?

• Sync Banshee library data.

  - by Dom

  I use Banshee to organise my music, I particularly like its scoring system and I have smart playlists based on it. However, I have two versions of my music library, one on each of my computers. As one of the computers is small I only have a favourite set of songs on that computer rather than my whole collection. The computers are not on a local network, but I do use Ubuntu One for file sharing between them. Is there any way I can synchronise song data (play count, score, skip count ...) and playlist data (including smart playlists that include songs based on this data) between the two computers? This would only be relevant of course for the songs that exist on both computers, the songs that exist on only one would need to be ignored. I did consider putting the library data file (I think it is .xml but I'm not sure) into the shared file and creating a symbolic link to it, but then I wouldn't be able to have a different set of songs on each computer. Thank you.

• What is preferred strategies for cross browser and multiple styled table in CSS?

  - by jitendra

  What is preferred strategies for cross browser and multiple styled table in CSS? in default css what should i predefined for <table>, td, th , thead, tbody, tfoot I have to work in a project there are so many tables with different color schemes and different type of alignment like in some table , i will need to horizontally align data of cell to right, sometime left, sometime right. same thing for vertical alignment, top, bottom and middle. some table will have thin border on row , some will have thick (same with column border). Some time i want to give different background color to particular row or column or in multiple row or column. So my question is: What code should i keep in css default for all tables and how to handle table with different style using ID and classes in multiple pages. I want to do every presentational thing with css. How to make ID classes for everything using semantic naming ? Which tags related to table can be useful? How to control whole tables styling from one css class?

• What could be a reason for cross-platform server applications developer to make his app work in multiple processes?

  - by Kabumbus

  So we consider a server app development - heavily loaded with messing with big data streams.An app will be running on one powerful server. a server app shall be developed in form of crossplatform application - so to work on Windows, Mac OS X and Linux. So same code many platforms for standing alone server architecture. We wonder what benefits does distributing applications not only over threads but over processes as wall would bring to programmers and to server end users and why? Some people sad to me that even having 48 cores, 4 process threads would be shared via OS throe all cores... is it true BTW?

• What to do with a site that has multiple languages in Google Analytics...

  - by stephmoreland

  We have a site that has four "streams" for language and each language has different content based on that language and location (US English, Spanish, Canadian English and Canadian French). I'm wondering if I have to set up accounts for each stream so that we can see the stats from each stream only, or do I use one account and somehow tell GA to separate the different streams based on language. For example, the US English site starts at (/en/) while the Canadian English site starts at (/ca_en/), etc.

• May I give a single class multiple responsibilities if only one will ever be reusable?

  - by lnluis

  To the extent that I understand the Single Responsibility Principle, a SINGLE class must only have one responsibility. We use this so that we can reuse other functionalities in other classes and not affect the whole class. My question is: what if the entity has only one purpose that really interacts with the system, and that purpose won't change? Do you have to separate the implementations of your methods into another class and just instantiate those from your entity class? Or to put it another way... Is it ok to break the SRP if you know those functions will not be reusable in the future? Or is it better to assume that we do not know if the functionalities of these methods will be reusable or not, and so just abstract them to other classes?

• Hosting and domain registrations for multiple clients under a single hosting account of mine?

  - by letseatfood

  I am finally getting regular work designing, developing, and deploying websites for small businesses and individuals. So far the websites utilize single-user content management systems, so the websites create, as far as I know, minimal load on the shared servers. I have always required that each of my clients purchase annual shared hosting at Dreamhost. For domain registration, I ask that they register with Dreamhost, but some already have a registered domain elsewhere and this is fine with me. I do this so the billing issues are the client's responsibility, not mine. My question is: Since I can register unlimited domains and connect them to my one shared hosting account at Dreamhost, should I not be requiring clients to individually pay for shared hosting and a domain? Should I actually be paying for one hosting account and then hosting all of my client's websites on that account? As I said before, I currently have each client buy their own hosting, because I feel that, for example, if there is high traffic to their site, there would be less a chance of the site going down than if their site was hosted with many others on one account. I am famous for being long-winded, please let me know if I can clarify at all. Thanks!

• Can I use one set of images to represent multiple sprites in Java?

  - by mal

  I've got a game that has 3 basic sprites, at the moment I'm loading 8 images into each sprite for animating. Each character class has a sprite object. if I've got 10 characters on screen at once then that's 80 images loaded in to memory. Can I make a central sprite class that only holds 8 images for each of the 3 sprites, then get the character objects to request the relevant images from the central sprite class, thereby massively reducing the memory required for the images?

• Is the size of a struct required to be an exact multiple of the alignment of that struct?

  - by Steve314

  Once again, I'm questioning a longstanding belief. Until today, I believed that the alignment of the following struct would normally be 4 and the size would normally be 5... struct example { int m_Assume_32_Bits; char m_Assume_8_Bit_Bytes; }; Because of this assumption, I have data structure code that uses offsetof to determine the distance in bytes between two adjacent items in an array. Today, I spotted some old code that was using sizeof where it shouldn't, couldn't understand why I hadn't had bugs from it, coded up a unit test - and the test surprised me by passing. A bit of investigation showed that the sizeof the type I used for the test (similar to the struct above) was an exact multiple of the alignment - ie 8 bytes. It had padding after the final member. Here is an example of why I never expected this... struct example2 { example m_Example; char m_Why_Cant_This_Be_At_Offset_6_Bytes; }; A bit of Googling showed examples that make it clear that this padding after the final member is allowed - for example http://en.wikipedia.org/wiki/Data_structure_alignment#Data_structure_padding (the "or at the end of the structure" bit). This is a bit embarrassing, as I recently posted this comment - Use of struct padding (my first comment to that answer). What I can't seem to determine is whether this padding to an exact multiple of the alignment is guaranteed by the C++ standard, or whether it is just something that is permitted and that some (but maybe not all) compilers do. So - is the size of a struct required to be an exact multiple of the alignment of that struct according to the C++ standard? If the C standard makes different guarantees, I'm interested in that too, but the focus is on C++.

• what's a good approach to working with multiple databases?

  - by Riz

  I'm working on a project that has its own database call it InternalDb, but also it queries two other databases, call them ExternalDb1 and ExternalDb2. Both ExternalDb1 and ExternalDb2 are actually required by a few other projects. I'm wondering what the best approach for dealing with this is? Currently, I've just created a project for each of these external databases and then generated Edmx and entities using the entity-framework approach. My thought was that I could then include these projects in any of my solutions that require access to these databases. Also, I don't have any separate business layers. I just have a solution like below: Project.Domain ExternalDb1Project.Domain ExternalDb2Project.Domain Project.Web So my Domain projects contain the data access as well as the POCOs generated by Entity Framework and any business logic. But I'm not sure if this is a good approach. For example if I want to do Validation in my Project.Domain on the entities in the InternalDb, it's fine. But if I want to do Validation for entities from either of the ExternalDbs, then I wonder where it should go? To be more specific, I retrieve Employees from ExternalDb1Project.Domain. However, I want to make sure they are Active. Where should this Validation go? How to architect a project like this at a high level? Also, I want to make sure that I use IoC for my data contexts so I can create Fakes when writing tests. I wonder where the interfaces for these various data contexts would reside?

• Is there a factory pattern to prevent multiple instances for same object (instance that is Equal) good design?

  - by dsollen

  I have a number of objects storing state. There are essentially two types of fields. The ones that uniquely define what the object is (what node, what edge etc), and the others that store state describing how these things are connected (this node is connected to these edges, this edge is part of these paths) etc. My model is updating the state variables using package methods, so all these objects act as immutable to anyone not in Model scope. All Objects extend one base type. I've toyed with the idea of a Factory approach which accepts a Builder object and constructs the applicable object. However, if an instance of the object already exists (ie would return true if I created the object defined by the builder and passed it to the equal method for the existing instance) the factory returns the current object instead of creating a new instance. Because the Equal method would only compare what uniquely defines the type of object (this is node A to node B) but won't check the dynamic state stuff (node A is currently connected to nodes C and E) this would be a way of ensuring anyone that wants my Node A automatically knows its state connections. More importantly it would prevent aliasing nightmares of someone trying to pass an instance of node A with different state then the node A in my model has. I've never heard of this pattern before, and it's a bit odd. I would have to do some overriding of serialization methods to make it work (ensure that when I read in a serilized object I add it to my facotry list of known instances, and/or return an existing factory in its place), as well as using a weakHashMap as if it was a weakHashSet to know whether an instance exists without worrying about a quasi-memory leak occuring. I don't know if this is too confusing or prone to its own obscure bugs. One thing I know is that plugins interface with lowest level hardware. The plugins have to be able to return state that is different than my memory; to tell my memory when its own state is inconsistent. I believe this is possible despite their fetching objects that exist in my memory; we allow building of objects without checking their consistency with the model until the addToModel is called anyways; and the existing plugins design was written before all this extra state existed and worked fine without ever being aware of it. Should I just be using some other design to avoid this crazyness? (I have another question to that affect that I'm posting).

• Marching squares: Finding multiple contours within one source field?

  - by TravisG

  Principally, this is a follow-up-question to a problem from a few weeks ago, even though this is about the algorithm in general without application to my actual problem. The algorithm basically searches through all lines in the picture, starting from the top left of it, until it finds a pixel that is a border. In pseudo-C++: int start = 0; for(int i=0; i<amount_of_pixels; ++i) { if(pixels[i] == border) { start = i; break; } } When it finds one, it starts the marching squares algorithm and finds the contour to whatever object the pixel belongs to. Let's say I have something like this: Where everything except the color white is a border. And have found the contour points of the first blob: For the general algorithm it's over. It found a contour and has done its job. How can I move on to the other two blobs to find their contours as well?
