• First Project a big one, How much should we charge?

  - by confuzzled

  Two of my cousins and I started a freelance computer repair/web design business just to make some money on the side during college, and received our first major web design project about three weeks ago. Now we've created websites before, but it was mostly for family businesses and have never really charged money, and most of the websites have been static, and don't really require a CMS. This project, however, was a big one (for us anyways). We created a news site that had several categories, we created the banners, we created a classifieds page (not a web app just something static that they control). Several links, a few graphical assets, CSS drop down menu, RSS feed from a different news site, weather, all the normal stuff you would find on a regular news site. On top of that we put in all the usual Joomla stuff (search, Jcomments, Jslide pictures, JCE, etc.). Then we uploaded the first 10 articles they gave us, and we are going to train them how to use Joomla. Now, at first we decided for 700 dollars. I assumed they just wanted a simple blog like website where they can upload articles. But then we had a meeting, and they asked for a lot more. Note: we did not hard code the template from scratch, but customized the gantry framework to fit their needs. We did code quite a bit however. I estimate that we put in about 50-60 hours in total. I'm wondering if 700 dollars is a bit low, this price is definitely not set in stone. Please keep in mind that this is our first project, and we are newbies, please be kind. Thank You!

• How to determine if a 3D voxel-based room is sealed, efficiently

  - by NigelMan1010

  I've been having some issues with efficiently determining if large rooms are sealed in a voxel-based 3D rooms. I'm at a point where I have tried my hardest to solve the problem without asking for help, but not tried enough to give up, so I'm asking for help. To clarify, sealed being that there are no holes in the room. There are oxygen sealers, which check if the room is sealed, and seal depending on the oxygen input level. Right now, this is how I'm doing it: Starting at the block above the sealer tile (the vent is on the sealer's top face), recursively loop through in all 6 adjacent directions If the adjacent tile is a full, non-vacuum tile, continue through the loop If the adjacent tile is not full, or is a vacuum tile, check if it's adjacent blocks are, recursively. Each time a tile is checked, decrement a counter If the count hits zero, if the last block is adjacent to a vacuum tile, return that the area is unsealed If the count hits zero and the last block is not a vacuum tile, or the recursive loop ends (no vacuum tiles left) before the counter is zero, the area is sealed If the area is not sealed, run the loop again with some changes: Checking adjacent blocks for "breathable air" tile instead of a vacuum tile Instead of using a decrementing counter, continue until no adjacent "breathable air" tiles are found. Once loop is finished, set each checked block to a vacuum tile. Here's the code I'm using: http://pastebin.com/NimyKncC The problem: I'm running this check every 3 seconds, sometimes a sealer will have to loop through hundreds of blocks, and a large world with many oxygen sealers, these multiple recursive loops every few seconds can be very hard on the CPU. I was wondering if anyone with more experience with optimization can give me a hand, or at least point me in the right direction. Thanks a bunch.

• How do you keep your basic skills from atrophy?

  - by kojiro

  I've been programming for about 10 years, and I've started to migrate to more of a project management position. I still do coding, but less often now. One of the things that I think is holding me back in my career is that I can't "let go". I think I fear letting hard-won programming skills atrophy while I sit in meetings and annotate requirements. (Not to mention I don't trust people to write requirements who don't understand the code.) I can't just read books and magazines about coding. I'm involved in some open source projects in my free time, and stackoverflow and friends help a bit, because I get the opportunity to help people solve their programming problems without micromanaging, but neither of these are terribly structured, so it's tempting to work first on the problems I can solve easily. I guess what I'd like to find is a structured set of exercises (don't care what language or environment) that… …I can do periodically …has some kind of time requirement so I can tell if I've been goofing off …has some kind of scoring so I can tell if I'm making mistakes Is there such a thing? What would you do to keep your skills fresh?

• Problem graphics with ATI Radeon x1270 (RS690M) on Ubuntu 12.04

  - by Giuseppe Della Corte

  I'm Italian and so I apologize for my English! I'm a beginner to Ubuntu and I tried it on my desktop PC and it's fantastic, fast and fun! I decided to try it on my netbook Packard Bell DOT M/A and this is the configuration: AMD Athlon L110 1.2GHz 2GB of RAM ATI Radeon x1270 (RS690M) 150GB Hard Disk I installed Ubuntu 12.04 with Wubi (dualboot Windows 7 + Ubuntu 12.04), because the netbook does not have a DVD player! During the installation everything is OK, after it was installed I see mistakes in the graphical display! I see objects that are seen in different colors and moving (buttons, mouse pointer, text bar ... etc ...) At one point came not to see anything, such as this screenshot: The drivers are open, that is already installed in Ubuntu. Windows 7 video card runs fine, can run well Aero (transparent window effects), I can watch movies in HD and play some games with the Catalyst drivers from AMD. Now I ask a favor, you can help me solve this problem? Is there a fix for this driver or drivers different on the Internet? Thanks for your attention, good bye!

• svcbundle for easier SMF manifest creation

  - by Glynn Foster

  One of the new features we've introduced in Oracle Solaris 11.1 is a new utility called svcbundle. This utility allows for the easy creation of Service Management Facility (SMF) manifests and profiles, allowing you to take advantage of the benefits of automatic application restart without requiring you to have full knowledge of the XML file format that is used when integrating with the SMF. Integrating into SMF is one of the easiest and most obvious ways to take advantage of some of the mission critical aspects of the operating system, but many customers were often finding the initial learning curve of creating an XML manifest to be too hard. With the release of Oracle Solaris 11 11/11, SMF had a more integral part to play as more and more system configuration was starting to use the SMF configuration repository for the backend storage. This provides a number of aspects, including the ability to carefully manage customized administrative configuration, site specific configuration, and vendor provided configuration at different layers, helping to preserve them during system update. I've written a new article, Using svcbundle to Create SMF Manifests and Profiles in Oracle Solaris 11, to give you a feel for the help we can provide in converting your applications over to SMF, or doing some site wide configuration using profiles. This is the first pass at creating such a tool, so we'd love to hear feedback of your experiences using it.

• SMTP server to deliver mail to Rails app, how?

  - by Gunchars

  all, this is my first question and I hope I chose the right place to post it. Here's what I need help with: I've been looking for this all day and I'm having a hard time finding a SMTP mail server that would fit the following criteria: lightweight, does one thing and does it good is able to route and deliver local mail to a Rails application The second point could be accomplished in any number of ways. I'm running a VPS, so I have full freedom in how to implement this. It could, for example, put messages straight in the db, pipe them to a helper program that would then process them accordingly or also save messages in a mbox file and run a script after every received message. I'm building a small site so the traffic is not going to be a problem. If there are alternative ways to deliver messages to a Rails app, I'd gladly hear about them. Thank you. EDIT: After long searching, I think I've found what I was looking for. Exim is a mail server that can deliver local mail to pipes. Also, Rails 3 and ActionMailer can make it really easy to process the incoming mail. More info here: http://www.exim.org/exim-html-current/doc/html/spec_html/ch29.html http://guides.rubyonrails.org/action_mailer_basics.html#receiving-emails

• BusEnum2 and a Minor Bug Fix

  - by Kate Moss' Open Space

  The default root bus driver, BusEnum, enumerate and active drivers one by one in synchronized manner. It is not only slowing the boot time but in the even if any of driver's init function (XXX_init) get hanged, the whole system won't boot at all. There is a sample of enhanced root bus driver, BusEnum2, on the http://msdn.microsoft.com/en-us/library/dd187254.aspx The page provides the sample code and the detail explanation of the design concept. With multi-threaded BusEnum2 on CE7 with SMP enabled system, the scalability is even more significant. Since you have more than one processor and it can load drivers in parallel! Everything looks good so far, except to there is a small bug in the sample code. Fortunately, it is easy to fix. But hard to trace if you ever enc outer it! The BUSENUM2 flag only defined in BUSENUM2\BUSDEF\sources but not in BUSENUM2\BUSENUM\sources. The DeviceFolder is implemented in BUSENUM2\BUSDEF but the instance is created in BUSENUM2\BUSENUM\busenum.cpp, so the result is it allocates less memory than actual need.   Add   CDEFINES=$(CDEFINES) -DBUSENUM2   into BUSENUM2\BUSENUM\sources and the problem fixed!

• Am I an idealist?

  - by ereOn

  This is not only a question, this is also a call for help. Since I started my career as a programmer, I always tried to learn from my mistakes. I worked hard to learn best-practices and while I don't consider myself a C++ expert, I still believe I'm not a beginner either. I was recently hired into a company for C++ development. There I was told that my way to work was "against the rules" and that I would have to change my mind. Here are the topics I disagree with my hierarchy (their words): "You should not use separate header files for your different classes. One big header file is both easier to read and faster to compile." "Trying to use different headers is counter-productive : use the same super-set of headers everywhere, and enforce the use #pragma hdrstop to hasten compilation" "You may not use Boost or any other library that uses nested directories to organize its files. Our build-machine doesn't work with nested directories. Moreover, you don't need Boost to create great software." One might think I'm somehow exaggerated things, but the sad truth is that I didn't. That's their actual words. I believe that having separate files enhance maintainability and code-correctness and can fasten compilation time by the use of the proper includes. Have you been in a similar situation? What should I do? I feel like it's actually impossible for me to work that way and day after day, my frustration grows.

• How exactly to implement multiple threads in a game

  - by xerwin

  So I recently started learning Java, and having a interest in playing games as well as developing them, naturally I want to create game in Java. I have experience with games in C# and C++ but all of them were single-threaded simple games. But now, I learned how easy it is to make threads in Java, I want to take things to the next level. I started thinking about how would I actually implement threading in a game. I read couple of articles that say the same thing "Usually you have thread for rendering, for updating game logic, for AI, ..." but I haven't (or didn't look hard enough) found example of implementation. My idea how to make implementation is something like this (example for AI) public class AIThread implements Runnable{ private List<AI> ai; private Player player; /*...*/ public void run() { for (int i = 0; i < ai.size(); i++){ ai.get(i).update(player); } Thread.sleep(/* sleep until the next game "tick" */); } } I think this could work. If I also had a rendering and updating thread list of AI in both those threads, since I need to draw the AI and I need to calculate the logic between player and AI(But that could be moved to AIThread, but as an example) . Coming from C++ I'm used to do thing elegantly and efficiently, and this seems like neither of those. So what would be the correct way to handle this? Should I just keep multiple copies of resources in each thread or should I have the resources on one spot, declared with synchronized keyword? I'm afraid that could cause deadlocks, but I'm not yet qualified enough to know when a code will produce deadlock.

• Impact on SEO of adding categories/tags in front of the HTML title [closed]

  - by Mad Scientist

  Possible Duplicate: Does the order of keywords matter in a page title? All StackExchange sites add the most-used tag of a question in front of the HTML title for SEO purposes. On Stackoverflow for example this is usually the programming language, so you end up with a title like python - How do I do X? This has obviously an enourmous benefit on SEO as the programming language is an extremely important keyword that is very often omitted from the title. Now, my question is for the cases where the tag isn't an important keyword missing from the title, but just a category. So on Biology.SE for example one would have questions like biochemistry - How does protein X interact with Y? or on Skeptics medical science - Do vaccines cause autism? Those tags are usually not part of the search terms, they serve to categorize the content but users don't use those tags in their searches. How harmful is adding tags that are not used in searches in terms of SEO? Is there any hard data on the impact this practise might have on SEO? The negative aspects I can imagine, but have no data to show that it is actually a problem are: I heard that search engines dislike keyword stuffing and this might trigger some defense mechanisms against that It's a practise associated with less reputable sites, a keyword in front that doesn't fit the actual title well might look suspicious to some users. It wastes precious space in the title shown in search results.

• Oracle NoSQL Database: Cleaner Performance

  - by Charles Lamb

  In an earlier post I noted that Berkeley DB Java Edition cleaner performance had improved significantly in release 5.x. From an Oracle NoSQL Database point of view, this is important because Berkeley DB Java Edition is the core storage engine for Oracle NoSQL Database. Many contemporary NoSQL Databases utilize log based (i.e. append-only) storage systems and it is well-understood that these architectures also require a "cleaning" or "compaction" mechanism (effectively a garbage collector) to free up unused space. 10 years ago when we set out to write a new Berkeley DB storage architecture for the BDB Java Edition ("JE") we knew that the corresponding compaction mechanism would take years to perfect. "Cleaning", or GC, is a hard problem to solve and it has taken all of those years of experience, bug fixes, tuning exercises, user deployment, and user feedback to bring it to the mature point it is at today. Reports like Vinoth Chandar's where he observes a 20x improvement validate the maturity of JE's cleaner. Cleaner performance has a direct impact on predictability and throughput in Oracle NoSQL Database. A cleaner that is too aggressive will consume too many resources and negatively affect system throughput. A cleaner that is not aggressive enough will allow the disk storage to become inefficient over time. It has to Work well out of the box, and Needs to be configurable so that customers can tune it for their specific workloads and requirements. The JE Cleaner has been field tested in production for many years managing instances with hundreds of GBs to TBs of data. The maturity of the cleaner and the entire underlying JE storage system is one of the key advantages that Oracle NoSQL Database brings to the table -- we haven't had to reinvent the wheel.

• Brain picking during job interview

  - by mark

  Recently, I had a job interview at a big Silicon Valley company for a senior software developer/R&D position. I had several technical phone screens, an all day on-site interview and more technical phone screens for another position later. The interviews went really well, I have a PhD and working experience in the area I was applying for yet no offer was made. So far, so good. It was an interesting experience, I am employed, absolutely no hard feelings about this. Some of the interviewers asked really detailed questions to the point of being suspicious about new technologies I have been working on. These technologies are still in development and have not come to market yet. I know some major hardware/software companies are working on this too. I have had many interviews before and based on my former interviewing experience and the impression some of the interviewers left behind, I know now all this company wanted from me is to extract some ideas about what I did in this field. Remember, I am referring to a R&D position, not the standard software developer stuff. Has anybody encountered this situation so far? And how did you deal with it? I am not so much concerned about "stealing" ideas but more about being tricked into showing up for an interview when there is no intension to hire anyway. I am considering refusing technical interviews in the future and instead proposing a trial period in which the company can easily reconsider its hiring decision.

• Sys Admins are kind of like gods, aren't they? [closed]

  - by user75798

  A systems administrator has root access to the entire system. There is nothing they cannot do. They are omnipotent. Their power is absolute. Nothing dan stand before them. Like Sauron, the Dark Lord, they do not share power. There can be but one root. Else contradiction at the most fundamental level is possible, and that can not be tolerated. The sys admin's power is unconditional and non-negotiable. To be a sys admin is like being a god. (And if they are a god, what is the religion?) There is an old saying that absolute power corrupts absolutely. I wonder whether being a sys admin has ended up warping an individual. Perhaps a sys admin has become crazed or even gone berserk? Surely sys admins must need to be very level headed people. For example, imagine being 'the' sys admin for the NSA. (What an awesome job that would be!) Think about the access to data, the encryption keys, the secrets... Perhaps one day a sys admin might go bonkers, turn up for work and 'uninstall the entire NSA'! :) But you would have the same sorts of responsibilities working at a bank or other organization. I wonder whether much emphasis is put on ensuring that sys admins are level headed in the first place and kept sweet in the second. Do they get paid well? I am sure they do not receive half of what they are worth, considering all the hard earned knowledge they have had to gain and the massive responsibility they have.

• Need alternative to Accessibility's "Locate Pointer" to visually highlight the mouse.

  - by fred.bear

  Update: See end of quetion: A black-on-white cross-hair/I-bar mouse-pointer is soemtimes hard foe me to spot in amongst black-on-white text. I've tried "Accessibility / Mouse Accessibility / Locate Pointer" .. which will: Show pointer position when Control is presssed It works (to a point), but it does have a notable problem, which renders it inpractical. It has the uncanny side-effect of disallowing all Control key navigation while editing a file/dir name in Nautilus (F2).. Just touching the Control key drops it out of edit mode, which means I can't keyboard paste, move-L/R word etc... So, I'm looking for an alternative. I've tried Compiz's Water Effect, but I need something which is sharper, faster, and localized to the pointer. Compiz's Show Mouse (with fire) is no suitable. I'm really lookingf for an analog of "Accessibility / Locate Pointer": * ie. I hit Control (only).. and it blips a quick visual pulse. UPDATE: I've just realized why I can't find my mouse so often! ... It's because it is isn't there !!! ... Two apps I use a lot, Gedit and Konsole (KDE Terminal; it renders unicode better), ... dissolve the mouse-pointer to invisible after the first key is typed ... and Konsole does it after a few seconds of idle-time... like a video-player option: "hide the mouse".. Well I don't use the mouse much, and I thought it was juse my eyesight (which does rely a lot on Compiz's zoom)... I discovered it when I installed a "novelty" app, called Geyes from gnome-applets ("A goofy set of eyes for the GNOME panel. They follow your mouse.") ... It could follow the mouse better than me! :)

• Fiction that includes BASIC programs [closed]

  - by Clinton Blackmore

  Back in what must've been the mid-80s, when every microcomputer included BASIC and Choose Your Own Adventure Books were really popular, there were some novels that had BASIC programs listed in the text, for you to type in and further enjoy. For example, as I recall, in one of these books, the adventurers were infiltrating an undersea base (and eventually wiped the bad guy's data storage [I do believe it was a hard drive, even though they were uncommon then]). One of the programs involved a game were you piloted a submarine and had to avoid or shoot sharks. The code was in BASIC; minor changes (such as 'CLS' - 'HOME') had to be made for your specific computer, and it used good old 40-column text-mode to display the action. IIRC, the plot never depended upon the programs. My question is, does anyone else recall these sorts of books? Do you know any titles that I could look for, or of any online? I am toying with the idea of writing a story like this (no, not in BASIC!), and would really like to see how it was done, back in the day.

• How does datomic handle "corrections"?

  - by blueberryfields

  tl;dr Rich Hickey describes datomic as a system which implicitly deals with timestamps associated with data storage from my experience, data is often imperfectly stored in systems, and on many occasions needs to retroactively be corrected (ie, often the question of "was a True on Tuesday at 12:00pm?" will have an incorrect answer stored in the database) This seems like a spot where the abstractions behind datomic might break - do they? If they don't, how does the system handle such corrections? Rich Hickey, in several of his talks, justifies the creation of datomic, and explains its benefits. His work, if I understand correctly, is motivated by core the insight that humans, when speaking about data and facts, implicitly associate some of the related context into their work(a date-time). By pushing the work required to manage the implicit date-time component of context into the database, he's created a system which is both much easier to understand, and much easier to program. This turns out to be relevant to most database programmers in practice - his work saves everyone a lot of time managing complex, hard to produce/debug/fix, time queries. However, especially in large databases, data is often damaged/incorrect (maybe it was not input correctly, maybe it eroded over time, etc...). While most database updates are insertions of new facts, and should indeed be treated that way, a non-trivial subset of the work required to manage time-queries has to do with retroactive updates. I have yet to see any documentation which explains how such corrections, or retroactive updates, are handled by datomic; from my experience, they are a non-trivial (and incredibly difficult to deal with) subset of time-related data manipulation that database programmers are faced with. Does datomic gracefully handle such updates? If so, how?

• OpenGL lighting with dynamic geometry

  - by Tank

  I'm currently thinking hard about how to implement lighting in my game. The geometry is quite dynamic (fixed 3D grid with custom geometry in each cell) and needs some light to get more depth and in general look nicer. A scene in my game always contains sunlight and local light sources like lamps (point lights). One can move underground, so sunlight must be able to illuminate as far as it can get. Here's a render of a typical situation: The lamp is positioned behind the wall to the top, and in the hollow cube there's a hole in the back, so that light can shine through. (I don't want soft shadows, this is just for illustration) While spending the whole day searching through Google, I stumbled on some keywords like deferred rendering, forward rendering, ambient occlusion, screen space ambient occlusion etc. Some articles/tutorials even refer to "normal shading", but to be honest I don't really have an idea to even do simple shading. OpenGL of course has a fixed lighting pipeline with 8 possible light sources. However they just illuminate all vertices without checking for occluding geometry. I'd be very thankful if someone could give me some pointers into the right direction. I don't need complete solutions or similar, just good sources with information understandable for someone with nearly no lighting experience (preferably with OpenGL).

• Newbie tips, please [closed]

  - by eXeP

  So, I just got a new computer and I want to put Ubuntu on my old laptop. I just need few tips before installing it. 1.Programs, where to download, how to download, what is the "ending" (windows has .exe) 2. How much is command line involved? And where to get the most usual commands? 3.Few programs you recommend (graphics editing, IDE, video player, web browser) 4. Do I have to download drivers when installing new OS? I plan on getting fully rid of Windows. I have no idea of the name of my graphics card, so how do I can get to know what it is if I have to download drivers? (I don't know the name because it's not on the original box, or anywhere on the internet, believe me) 5. When installing new OS does it destroy everything else on the hard drive? 6. Anti-virus, do I need one? I'm not super paranoid, and I don't visit "shady" sites. Please note that I have never used linux, or any other OS than Windows and sorry for my bad english. If this is the wrong place to post this, then please remove this. Thank you.

• How to improve my backup strategy (rsync)?

  - by GUI Junkie

  I've seen the QAs about backup solutions, but I'm asking anyway. One because it's a personal situation I haven't solved yet, and two, because the answer can be useful for others. My situation is rather simple. I have two computers with two users and one external hard-drive. I want to sync/backup a shared directory. Currently I use rsync with the -azvu options to sync to the external drive. My problem is the round-trip. All deleted files are restored! Using rsync I'm doing Computer A --> External disk --> Computer A Computer B --> External disk --> Computer B (I should probably do External disk -- Computer A as a last step) I've seen 'bup' mentioned and other QA talk about dropbox + rsync... Another option is maybe to delete files from rsync? Can my running backup strategy be improved in some other way?

  I have worked for small, medium, large, and extra large companies and they have something in common with ships. These metaphors have been used before, I know, but I will have a go at them.The small company is like a speed boat, exciting and fast, and can turn on a dime, literally. Captain and crew share a lot of the work. A speed boat has a short range and needs to refuel a lot. It has difficulty getting through bad weather. (Small companies often live quarter to quarter. By the way, if a larger company is living quarter to quarter, it is taking on water.)The medium company is is like a battleship. It can maneuver, has a longer range, and the crew is focused on its mission. Its main concern are the other battleships trying to blow it out of the water, but it can respond quickly. Bad weather can jostle it, but it can get through most storms.The large company is like an aircraft carrier; a floating city. It is well-provisioned and can carry a specialized load for a very long range. Because of its size and complexity, it has to be well-organized to be effective and most of its functions are specialized (with little to no functional cross-over). There are many divisions and layers between Captain and crew. It is not very maneuverable; it has to set its course well in advance and have a plan of action.The extra large company is like a cruise liner. It also has to be well-organized and changes in direction are often slow. Some of the people are hard at work behind the scenes to run the ship; others can be along for the ride. They sail the same routes over and over again (often happily) with the occasional cosmetic face-lift to the ship and entertainment. It should stay in warm, friendly waters and avoid risky speed through fields of ice bergs.I have enjoyed my career on the various Ships of Technical Writing, but I get the most of my juice from the battleship where I am closer to the campaign and my contributions have the greater impact on success.Mark Metcalfewww.linkedin.com/in/MarkMetcalfe

• I've inherited 200K lines of spaghetti code -- what now?

  - by kmote

  I hope this isn't too general of a question; I could really use some seasoned advice. I am newly employed as the sole "SW Engineer" in a fairly small shop of scientists who have spent the last 10-20 years cobbling together a vast code base. (It was written in a virtually obsolete language: G2 -- think Pascal with graphics). The program itself is a physical model of a complex chemical processing plant; the team that wrote it have incredibly deep domain knowledge but little or no formal training in programming fundamentals. They've recently learned some hard lessons about the consequences of non-existant configuration management. Their maintenance efforts are also greatly hampered by the vast accumulation of undocumented "sludge" in the code itself. I will spare you the "politics" of the situation (there's always politics!), but suffice to say, there is not a consensus of opinion about what is needed for the path ahead. They have asked me to begin presenting to the team some of the principles of modern software development. They want me to introduce some of the industry-standard practices and strategies regarding coding conventions, lifecycle management, high-level design patterns, and source control. Frankly, it's a fairly daunting task and I'm not sure where to begin. Initially, I'm inclined to tutor them in some of the central concepts of The Pragmatic Programmer, or Fowler's Refactoring ("Code Smells", etc). I also hope to introduce a number of Agile methodologies. But ultimately, to be effective, I think I'm going to need to hone in on 5-7 core fundamentals; in other words, what are the most important principles or practices that they can realistically start implementing that will give them the most "bang for the buck". So that's my question: What would you include in your list of the most effective strategies to help straighten out the spaghetti (and prevent it in the future)?
