• Is it bad practice for a module to contain more information than it needs?

  - by gekod

  I just wanted to ask for your opinion on a situation that occurs sometimes and which I don't know what would be the most elegant way to solve it. Here it goes: We have module A which reads an entry from a database and sends a request to module B containing ONLY the information from the entry module B would need to accomplish it's job (to keep modularity I just give it the information it needs - module B has nothing to do with the rest of the information from the read DB entry). Now after finishing it's job, module B has to reply to a module C if it succeeded or failed. To do this module B replies with the information it has gotten from module A and some variable meaning success or fail. Now here comes the problem: module C needs to find that entry again BUT the information it has gotten from module B is not enough to uniquely find the exact same entry again. I don't think that module A giving more information to module B which it doesn't need to do it's job but which it could then give back to module C would be a good practice because this would mean giving some module information it doesn't really need. What do you think?

• What's the proper way to merge two projects in source control software

  - by Mallow

  I'm using Fossil-SCM to maintain my projects. Since I don't work in a team I usually have just a very linear branch of development: 1.0 - 1.1 - 1.2 I'm wondering what the procedure is when you have one project who's task is about to be given to a related project. And thereby rendering the first project obsolete. Although I tend to rewrite most of my code if I don't remember having already written it, I still would like to keep the code archived. And I'ld rather not have a fossil repo that just is dead. Can I merge it? Is that the proper way of handling this? For example the code was extracting data from an excel file in order to format an HTML page. Now, I've convinced my employer to move their excel spreadsheet into a database to decrease redundancy, increase efficiency and yaddy yadda. Since I can now make logical queries that don't have to jump hoops to preform using the database I won't need the extra vbs files that originally manipulated the excel file. Technically I would be porting part of the existing code into the current new project. Since it already has it's own trunk, would it be advisable to combine the trunk of a different project to this one, and how would I do that exactly?? SO I guess my tree would look like this, and I haven't seen examples of software branching that resemble this inverted tree before so I'm wondering what the norm for a situation like this?

• Skype Silent Mode

  - by jack

  So Skype has a silent mode: e.g. it won't alert you in any way about incoming calls/messages. I'd like to use that mode while working to keep Skype from distracting me. I'd rather not quit the program or signoff during that time. Is there a simple way to put Skype in that mode? There's an option for it in their SDK but not in the software. There are third party apps that do it (among other things), but there doesn't seem to be a simple solution for this. Help please!

• how to choose a web framework and javascript library?

  - by Trylks

  I've been procrastinating learning some framework for web apps w/ some library for AJAX, something like django with prototype, or turbogears with mootools, or zeta components with dojo, grok, jquery, symfony... The point is to spend some of my spare time, have "fun" and create cool stuff that hopefully is some useful. I think maybe I wouldn't like something like GWT or pyjamas because I wouldn't like to "get married" with some technology, I want to keep my freedom to add another javascript library, and so on. I didn't decide even the language yet, but I think I'd prefer python. PHP could be fine if there is some framework that is nice enough. Besides that, I don't even know where to start. I don't feel like learning a framework to then realize there is something that I cannot comfortably do, switch to another framework then find that a third framework has something really cool, etc. And the same goes for javascript libraries. So, some guidance would be really appreciated. I don't really know why are so many options available and what do they aim for, I guess some of them focus on some aspects and some on others, but I just want to make cool and nice apps that I can easily maintain, without spending too much time on coding or learning and avoiding the "trapped in the framework" feeling, when doing something is awfully complicated (or even impossible) with compared with the rest of things or doing that same thing on a different framework. I guess in the end I'll go for django and jquery since they are the most widely used options, afaik, but if I was going for the most widely used options I guess I should choose Java or PHP (I don't really like Java for my spare time, but php is not so bad), so I preferred to ask first. I think the question has to consider both, framework and library, since sometimes they are coupled. I think this is the place to ask this kind of things, sorry if not, and thank you.

• Nginx/FPM/PHP all php files say 'File not found.'

  - by Boon

  i just installed nginx 1.1.13 and php 5.4.0 on a centos 5.8 final 64bit machine. Nginx and PHP/Fpm are running, and I can run php scripts via ssh command line, but in the browser I keep getting 'File not found.' errors on all my PHP files. This is how I have my nginx.conf handle PHP scripts: location ~ \.php$ { root /opt/nginx/html; fastcgi_pass unix:/tmp/fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /opt/nginx/html$fastcgi_script_name; include fastcgi_params; } This is a direct copy/paste from my other servers, where it works fine with this setup (but they run older versions of php/fpm). Why am I getting those errors?

• How to run an Application as another user?

  - by takpar

  I use krusader for file management stuff. the problem is that apache's DocumentRoot should be under chown www-data:www-data /path/to/www. so using krusader (which is run under my account) I've not write access to /path/to/www while I really need. I don't know how other developers can continue doing things with such a restriction! I wondered if I could run krusader as www-data then I will be able to easily play with files. but using su - www-data asked me for www-data's password!! So, how can I run an application (like krusader) as another user (like www-data) in Gnome? or is there any other solution for my case? (tough I'm really curious to know the answer!) keep in mind that I know I can run it as root! but this will cause some permission problems when using cp and mkdir, you know. PS: sudo and gksudo did not help: $ gksudo -u -www-data krusader No protocol specified krusader: cannot connect to X server :0.0 Final Note: according the best answer, i did chmod u+w /path/to/www and my problem solved. but i still has not been succeeded in opening krusader as another user!

• Virtual Desktop Provisioning - Vmware View 5.2 Maintenance Questions

  - by Lee J. DeAngelis

  Currently running an environment of about 400 VMware View 5.2 virtual Desktops. The environment runs pretty efficiently but we sometimes run into problems with certain pools from time to time. Just recently we had a pool that was causing high write latency when users logged in. It just happened all of a sudden and had been working fine for weeks. On a hunch we completely broke down the pool and re-provisioned it from a new image. This corrected the problem. In fact every real issue we've had so far was fixed by a recompose or complete break down and re-provisioning of one pool or another.Our environment consists of Cisco UCS and Netapp 3240s using flashcache running VMware View 5.2. My questions are: What are some maintenance best practices other VDI admins are using? How often are you recomposing? rebalancing? re-provisioning? How long should you keep base image snapshots around?

• ubuntu: mumble 1.2.2 in Karmic

  - by Dan

  Karmic only has mumble 1.1.8, but if I want to connect to a 1.2 server I need to upgrade... So I would like to know how I can upgrade to mumble 1.2.2 without messing myself up for later when I upgrade to 10.04 and beyond... I just want a smooth transition into the next versions of mumble. Is there anyway to upgrade to this newer version and either keep it in the package manager or make it not interfere with the natural upgrades the program will later recieve from the package manager? Thanks, Dan

• Nginx Ip Whitelist

  - by Will

  Is it possible to create a ip whitelist for my nginx proxy server without adding allow or deny in the config file is it possible i can get nginx to link to a separate database to check if the user is allowed to access the website . Ideally i could do with nginx linking to an external database or at minimum a list off allowed ips on the same server so i can easily update the list whit out restarting nginx every time. In the future i would like to link nginx to my website and a user will login and there ip will be linked to there account and they will be able to update there ip if it has changed to there new one to grant them access so i need to keep in mind that it would be easyer to do this if i have external list off ips in some kind off database any help is apreshiated

• How to determine the end of list has been reached?

  - by Sweta Dwivedi

  I'm trying to animate my object according to a set of recorded values from kinect skeleton stream by saving the (x,y,z) stream from the skeletal data into a list and then set my objects x and y position from the x,y of the list. However, once the list end has been reached it starts to animate again from the start. I don't want that - I just want the model position to keep going in the positive X direction. Is there any way I can check if end of the list has been reached and to just update the model position in x direction? Or is there any other way to continue moving my sprite once the points in the list are over... i dont want it to start animating all the way again.. protected override void Update(GameTime gameTime) { //position += spriteSpeed * (float)gameTime.ElapsedGameTime.TotalSeconds; //// TODO: Add your update logic here using (StreamReader r = new StreamReader(f)) { string line; Viewport view = graphics.GraphicsDevice.Viewport; int maxWidth = view.Width; int maxHeight = view.Height; while((line = r.ReadLine()) != null) { string[] temp = line.Split(','); int x = (int) Math.Floor(((float.Parse(temp[0]) * 0.5f) + 0.5f) * maxWidth); int y = (int) Math.Floor(((float.Parse(temp[1]) * -0.5f) + 0.5f) * maxHeight); motion_2.Add(new Point(x, y)); } } position.X = motion_2[i].X; position.Y = motion_2[i].Y; i++; a_butterfly_up.Update(gameTime); a_butterfly_side.Update(gameTime); G_vidPlayer.Play(mossV); base.Update(gameTime); }

• Google sitemap HrefLang tag without the main site url

  - by Rashmi Pandit

  We have websites with multilingual content. e.g. http://www.example.com/about-us/ http://www.example.com/en-HK/about-us/ http://www.example.com/en-GB/about-us/ http://www.example.com/zn-CH/about-us/ We need to configure the hreflang tags in sitemap for Google to know that there are alternate links for the same pages in different languages. I know for the above example that my sitemap url tag would look like this: <url> <loc>http://www.example.com/about-us</loc> <xhtml:link rel="alternate" hreflang="en-GB" href="http://www.example.com/en-GB/about-us"/> <xhtml:link rel="alternate" hreflang="en-HK" href="http://www.example.com/en-HK/about-us"/> <xhtml:link rel="alternate" hreflang="zn-CH" href="http://www.example.com/zn-CH/about-us"/> <changefreq>daily</changefreq> <priority>0.8</priority> </url> However, if I don't have the main url but just the last three ones with en-HK, en-GB and zn-CH, then how should my url tag look? Should I just skip the loc tag and keep the three xhtml:link tags? Or can I specify any url in the loc tag and put the remaining two in xhtml:link tags? I am new to Google sitemaps. Any help is greatly appreciated. Thanks, Rashmi Edit: From the answer posted on http://stackoverflow.com/questions/18423624/sitemap-for-domain-with-multilanguage-site/18423803#18423803, for my example with sites in en-HK, en-GB and zn-CH, should there be three url tags, with each of them assigned to loc with the other two in xhtml:link?

• Keeping player aligned to grid in Pacman

  - by user17577

  I am making a Pacman game using XNA. The game is tile based, with each tile being 32 pixels. As the player moves, I need to know whenever it is perfectly on a tile (ie position of 32, 64, etc...) so that I can check to see if the next tile is free. I am using the following logic to test this. if (position.X % 32 == 0 && position.Y %32 == 0) { onTile = true; } I figure that I need to make the player's speed evenly divide 32. Everything works fine if I make the player's speed an integer such as 4 or 8. But if I make the speed something like 6.4, I end up with positions such as 64.00001, and my if statement no longer works correctly. How can I keep the player aligned with the grid, while allowing a wider range of player speeds than 1, 2, 4, 8, 16, and 32? Or is there some better way to go about this? Thanks

• Vector with Constant-Time Remove - still a Vector?

  - by Darrel Hoffman

  One of the drawbacks of most common implementations of the Vector class (or ArrayList, etc. Basically any array-backed expandable list class) is that their remove() operation generally operates in linear time - if you remove an element, you must shift all elements after it one space back to keep the data contiguous. But what if you're using a Vector just to be a list-of-things, where the order of the things is irrelevant? In this case removal can be accomplished in a few simple steps: Swap element to be removed with the last element in the array Reduce size field by 1. (No need to re-allocate the array, as the deleted item is now beyond the size field and thus not "in" the list any more. The next add() will just overwrite it.) (optional) Delete last element to free up its memory. (Not needed in garbage-collected languages.) This is clearly now a constant-time operation, since only performs a single swap regardless of size. The downside is of course that it changes the order of the data, but if you don't care about the order, that's not a problem. Could this still be called a Vector? Or is it something different? It has some things in common with "Set" classes in that the order is irrelevant, but unlike a Set it can store duplicate values. (Also most Set classes I know of are backed by a tree or hash map rather than an array.) It also bears some similarity to Heap classes, although without the log(N) percolate steps since we don't care about the order.

• Managing the Domino Effect (with Tutor Publisher Reports)

  - by [email protected]

  When an organization upgrades their business application or improves a process, it triggers changes that will reverberate throughout an organization, like a falling row of dominoes standing on end. A tangible and repeatable way to communicate change is with updated process documentation. But how do organizations get their arms around all the documents that are impacted by an application upgrade or process improvement? A small change in one place will trigger subsequent changes in other areas. A simple domino chain of questions can go like this. What screens have changed? Do the new screens change the process in place? In what procedural documents are the screens referenced? Who uses the screens and must be notified of the changes? What other documents are affected? Will the change affect current company policy? Tutor Publisher compiles focused, easy to read impact analysis reports of your process documentation library that answer these tough questions. Tutor reports make it easy to quickly target the information and documents that require updating. In turn, the updated documents are used to communicate the change. The Tutor writing methodology and Publisher reports provide organizations the means to confidently keep documentation in sync with the way the business runs. Start managing the domino effect in your organization. Get a grip on it here!

• Processing component pools problem - Entity Subsystem

  - by mani3xis

  Architecture description I'm creating (designing) an entity system and I ran into many problems. I'm trying to keep it Data-Oriented and efficient as much as possible. My components are POD structures (array of bytes to be precise) allocated in homogeneous pools. Each pool has a ComponentDescriptor - it just contains component name, field types and field names. Entity is just a pointer to array of components (where address acts like an entity ID). EntityPrototype contains entity name and array of component names. Finally Subsystem (System or Processor) which works on component pools. Actual problem The problem is that some components dependents on others (Model, Sprite, PhysicalBody, Animation depends on Transform component) which makes a lot of problems when it comes to processing them. For example, lets define some entities using [S]prite, [P]hysicalBody and [H]ealth: Tank: Transform, Sprite, PhysicalBody BgTree: Transform, Sprite House: Transform, Sprite, Health and create 4 Tanks, 5 BgTrees and 2 Houses and my pools will look like: TTTTTTTTTTT // Transform pool SSSSSSSSSSS // Sprite pool PPPP // PhysicalBody pool HH // Health component There is no way to process them using indices. I spend 3 days working on it and I still don't have any ideas. In previous designs TransformComponent was bound to the entity - but it wasn't a good idea. Can you give me some advices how to process them? Or maybe I should change the overall design? Maybe I should create pools of entites (pools of component pools) - but I guess it will be a nightmare for CPU caches. Thanks

• Disk / system configuration for log collection / syslog server

  - by Konrads

  I am looking into building a syslog / logging infrastructure and am pondering about some architecture best practices. Essentially, I see that a syslog system needs to support two conflicting workloads: log collection. Potentially massive streams of data need to be written quickly to disks and indexed. log querying. logs will be queried by both fixed fields such as date and source as well as text search. What is the best disk/system setup assuming I'd like to keep it to a single server for now? Should I use SSDs or ramdisk to off-load some processing? some disks in stripe and some in raid5? I am particularly eyeing Graylog2 with ElasticSearch/MongoDB

• How can I resolve component types in a way that supports adding new types relatively easily?

  - by John

  I am trying to build an Entity Component System for an interactive application developed using C++ and OpenGL. My question is quite simple. In my GameObject class I have a collection of Components. I can add and retrieve components. class GameObject: public Object { public: GameObject(std::string objectName); ~GameObject(void); Component * AddComponent(std::string name); Component * AddComponent(Component componentType); Component * GetComponent (std::string TypeName); Component * GetComponent (<Component Type Here>); private: std::map<std::string,Component*> m_components; }; I will have a collection of components that inherit from the base Components class. So if I have a meshRenderer component and would like to do the following GameObject * warship = new GameObject("myLovelyWarship"); MeshRenderer * meshRenderer = warship->AddComponent(MeshRenderer); or possibly MeshRenderer * meshRenderer = warship->AddComponent("MeshRenderer"); I could be make a Component Factory like this: class ComponentFactory { public: static Component * CreateComponent(const std::string &compTyp) { if(compTyp == "MeshRenderer") return new MeshRenderer; if(compTyp == "Collider") return new Collider; return NULL; } }; However, I feel like I should not have to keep updating the Component Factory every time I want to create a new custom Component but it is an option. Is there a more proper way to add and retrieve these components? Is standard templates another solution?

• Hack a Linksys Router into a Ambient Data Monitor

  - by Jason Fitzpatrick

  If you have a data source (like a weather report, bus schedule, or other changing data set) you can pull it and display it with an ambient data monitor; this fun build combines a hacked Linksys router and a modified toy bus to display transit arrival times. John Graham-Cumming wanted to keep an eye on the current bus arrival time tables without constantly visiting the web site to check them. His workaround turns a hacked Linksys router, a display, a modified London city bus (you could hack apart a more project-specific enclosure, of course), and a simple bit code that polls the bus schedule’s API, into a cool ambient data monitor that displays the arrival time, in minutes, of the next two buses that will pass by his stop. The whole thing could easily be adapted to another API to display anything from stock prices to weather temps. Hit up the link below for more information on the project.

• How not to suffer from ideologists when you're a pragmatic person?

  - by Lukas Eder

  My story: I'm a pragmatic person. Sometimes, the most simple solution to a problem to get the job done is the one that fits best for me, if its not an utter blasphemy and reproach to any design principles. Check out my answer to this question on stackoverflow. Simple. Works. Was accepted. Could be improved. Is clearly not perfect. And along comes this guy. He downvotes me, comments on the question how his answer is better, more accurate etc and calls me "plain wrong". Reminds me of this comic strip. :-) While on stackoverflow I can laugh at these things because those people are far away, in the real world I'm suffering from ideologies every now and then. Heck, I'm not creating a miracle piece of software, I need to keep that huge legacy thing running, and it's an adventure to me every day. I don't have the time or passion to beautify my code (or other people's code) to that extent. My question(s): How do you deal with ideologies / ideologists, when you're a pragmatic person? How do you deal with pragmatism / pragmatists, when you're an ideologic person? I'm interested in both point of views. Tell me your experience. But please, be fair, somewhat objective, and understand that you may NOT be entirely correct and your opinion is NOT the only true one... :-)

• Any good software to help me memorize passwords?

  - by Septagram

  I'm using KeePass(X) and other tools to keep most of my passwords. However, it turns out, there is still about half a dozen passwords I'm using on regular basis that I would prefer to just remember. So, do you people know of any good programs, preferably open-source, to train yourself using a particular password and thus to memorize it? I know I can remember a 96-bit entropy password rather well if I practice entering it 3 days, 5 minutes for each day, I just want a good software to simplify the process and exclude the possibility of shouldering or otherwise leaking the password.

• Calculating a child Position, Rotation and Scale values?

  - by Sergio Plascencia

  I am making my own game editor(just for fun) anyway I have problem that I had several days trying to resolve but I have been unsuccessful. Here goes... I have an object "A": Position: (3,3,3), Rotation: (45,10,0), Scale(1,2,2.5) And an object "B": Position: (1,1,1), Rotation: (10,34,18), Scale(1.5,2,1) I now make a parent/child relationship. "B" is a child of "A": A |--B When I do the relationship I need to re-calculate the Child("B") Position, Rotation and Scale such that it maintains its current position, rotation and scale(Location in world). So for child position "B" it would now be (-2, -2, -2) since now "A" it is center and (-2, -2, -2) will keep the object in its same position. I think I got the Position and scale figure out, but rotation I cant. So I was trying to figure out what to do and what I did is opened Unity and run the same example and I did noticed that when making an abject a child object the child object did not moved at all but had its Position, Rotation and Scale values changed(Related to the parent). For example: Unity (Parent Object "A"): Position: (0,0,0) Rotation: (45,10,0) Scale: (1,1,1) Unity (Child Object "B"): Position: (0,0,0) Rotation: (0,0,0) Scale: (1,1,1) When making it a parent child relation("B" is a child of "A") the child object("B") in its Rotation values now has: X: -44.13605 Y: -14.00195 Z: 9.851074 If I plug the same values to my editor(To the child "B" rotation X, Y, Z values) the object does not move at all. So I basically need to know how did Unity arrive at those rotation values for the child(What are the calculations?). If you can help and put all the equations for the Position, Rotation or Scale then I can double check I am doing it correctly but with the Rotation I really need help. Thanks!

• Disabling networkmanager for a specific interface

  - by bdonlan

  I'd like to do some experimentation with hostap without disabling my primary wireless interface. How do I tell networkmanager to keep its hands off a specific interface or interfaces while allowing it to continue managing all other interfaces normally? I'm using Ubuntu 9.04. (Wasn't sure if this should go on superuser or serverfault, as networkmanager isn't much of a 'server' tool - if it belongs on serverfault please feel free to move it) Edit: I've tried adding this to /etc/network/interfaces: allow-hotplug wlan2 iface wlan2 inet static address 192.168.49.1 netmask 255.255.255.0 But this has no apparent effect, even after restarting NetworkManager. Here's my /etc/NetworkManager/nm-system-settings.conf: [main] plugins=ifupdown,keyfile [ifupdown] managed=false Edit[2]: Looks like I needed to restart nm-system-settings, then NetworkManager.

• Paranoid Encryption

  - by Lord Jaguar

  Call me paranoid, but I really like to keep my stuff secret, but readily available on the cloud. So, asking this question. How safe and reliable is encryption software (e.g., truecrypt)? The reason I ask is that, what is I encrypt my data today with this software and after a couple of years, the software is gone ! What happens to my encrypted data? Is it equally safe to AES encrypt using 7-zip? Will it provide the same level or equivalent level of encryption as truecrypt or other encryption software? (I agree truecrypt will be better because of the container encryption it gives.) And what happens if 7-zip shuts down after 5 years? I am sorry if I am sounding paranoid, but I am coming back to my original question... Is there any application/software independent encryption? Meaning, can I encrypt with one software and decrypt with another so that I will not be dependent on just one vendor? I want my encryption to depend ONLY on the password and NOT on the encryption program/software? The next question, can I write my own program that does AES/stronger encryption when I give it a passphrase, so that I don't need to depend on third party software for encryption? If yes, which language supports the same? Can someone give me a heads up as to where to look for in case of writing my own encryption program?

• Are Plesk server backups useful?

  - by Michael T. Smith

  I'm working for a startup now, and I'm the programmer. Because of our small team size, I'm also handling the server management for now (until we get a dedicated server administrator.) I've never used Plesk before, and the server we're using (a Media Temple Dedicated Virtual server) had it installed when I got here. One of my first jobs was to set up backups: Plesk was already running it's nightly server-wide backups. I created a small script to dump the web app, it's DBs and any assets, tar them, store them, and then copy them to another small server we have (to backup the backups.) But, we're constantly running into hard drive space issues because of the Plesk backups. And I'm wondering, are they useful? If I have the web app and all of it's assets, I could easily enough get another server up and running. Do we need to keep running Plesk's backups? Thoughts?

• chrome memory and cpu footprint

  - by nmizar

  I've searched the forums for an answer but I couldn't find quite the answer I was looking for [1] , so I thought I it could as well be of interest to more people around here. I carry out a big part of my job on the browser (or for the browser, if you want to put it that way). I tend to use Chrome, because it's got natively many of the newest features that I need (DevTools stuff, mainly but not only). BTW, I'm usually running the last available Chrome version/build on a desktop Vaio with 4GB RAM and dual core CPU and Ubuntu 12.04 as distro and Gnome as window manager. So, I was curious about a) why does Chrome spawn so many threads even opening only three of four tabs and b) is there any way to allocate more memory to Chrome to prevent its performance from degrading? Thanks in advance, Nacho PS [1] I found threads about Chrome freezing or running out of memory but not about the reasons for this being so or for avoiding it to happen. PPS Of course, I could always buy a newer and more capable machine and that is exactly what I'm trying to evaluate: is this a question of outdated hardware or the problem will keep appearing on any (decently but not hugely sized) machine?
