• What kind of position matches my skills, experience and interests? [closed]

  - by Ryan

  I work in a large firm and my current job covers a variety of different duties. Due to several factors I am seriously considering finding a new job (hours, pay-cut, limited career growth). I have worked for the company nearly 4 years and almost 2 years ago I transitioned into more of a business analyst role (previously I was working in a client facing role for our audit group). In this role I have overseen all aspects of the development of a large scale re-platforming of our firm's key tool in analyzing investment portfolios. I gathered requirements, wrote specs, designed the UI and functionality, worked closely with developers (onshore and offshore) to see to it the implementation was correct, managed schedules and was the lead tester. This is a large scale system used by thousands of people around the world. I've also written Excel macros, reports in SQL, given trainings, written technical manuals, interfaced with senior managers and partners, etc. I've been on a couple interviews sporadically, most of which were for positions aimed at higher management consulting type positions, dealing with strategy, overall process management, project management, etc. What really interests me is the technical stuff and overseeing a project from beginning to end (although I would rather not have to do so many of the tasks on my own). I genuinely like a lot of what I do, but the company culture and attitude towards overworking people combined with my recent pay-cut (my overtime was cut due to a promotion to a higher level) has lead me to want to seek work elsewhere. The problem is - what type of work could I realistically do? I feel like traditional business analysis is too much business and not enough tech stuff, and I've really taken a shine lately to beefing up my programming abilities and creating small programs to automate things around work. I also feel that because my actual years of experience as a business analyst (figure 1.5 years realistically) puts me at a junior level doing a lot of grunt requirements gathering, when the work that I have been doing with my current company is more in line with what a Program Manager does (depending on your definition I guess). So in reality, when I'm job hunting I get a bit perplexed because I feel like the traditional BA stuff wouldn't really suit me, and even if it did it's usually something along the lines of 5-10 years experience for the type of work that is similar to what I've done (and I've also found most BA jobs to be contract only which at the moment I'm not too keen on). Program Manager is something that interests me, but again I feel like the experience is lacking because that's a much more senior position. Am I in some kind of career no-man's land? Any idea what would best suit me given my experience and abilities, as well as my interests? I plan to keep learning programming on the side, but don't expect to get a job being a straight programmer given my relative inexperience with programming.

• Is the Observer pattern adequate for this kind of scenario?

  - by Omega

  I'm creating a simple game development framework with Ruby. There is a node system. A node is a game entity, and it has position. It can have children nodes (and one parent node). Children are always drawn relatively to their parent. Nodes have a @position field. Anyone can modify it. When such position is modified, the node must update its children accordingly to properly draw them relatively to it. @position contains a Point instance (a class with x and y properties, plus some other useful methods). I need to know when a node's @position's state changes, so I can tell the node to update its children. This is easy if the programmer does something like this: @node.position = Point.new(300,300) Because it is equivalent to calling this: # Code in the Node class def position=(newValue) @position = newValue update_my_children # <--- I know that the position changed end But, I'm lost when this happens: @node.position.x = 300 The only one that knows that the position changed is the Point instance stored in the @position property of the node. But I need the node to be notified! It was at this point that I considered the Observer pattern. Basically, Point is now observable. When a node's position property is given a new Point instance (through the assignment operator), it will stop observing the previous Point it had (if any), and start observing the new one. When a Point instance gets a state change, all observers (the node owning it) will be notified, so now my node can update its children when the position changes. A problem is when this happens: @someNode.position = @anotherNode.position This means that two nodes are observing the same point. If I change one of the node's position, the other would change as well. To fix this, when a position is assigned, I plan to create a new Point instance, copy the passed argument's x and y, and store my newly created point instead of storing the passed one. Another problem I fear is this: somePoint = @node.position somePoint.x = 500 This would, technically, modify @node's position. I'm not sure if anyone would be expecting that behavior. I'm under the impression that people see Point as some kind of primitive rather than an actual object. Is this approach even reasonable? Reasons I'm feeling skeptical: I've heard that the Observer pattern should be used with, well, many observers. Technically, in this scenario there is only one observer at a time. When assigning a node's position as another's (@someNode.position = @anotherNode.position), where I create a whole new instance rather than storing the passed point, it feels hackish, or even inefficient.

• What kind of server do I need to handle 10 million requests and mySQL queries a day?

  - by Calvin

  I'm a new bie of server administration and I'm looking for a powerful hosting service to host my new website. This website is basically a back-end of an mobile online game, and it will: handle up to 10 million of HTTPS request and mySQL queries a day store up to 2000 GB file on the hard disk transfer probably 5000 GB data in and out per month it runs on PHP and mySQL have 10 million records in mySQL database, for each record there are 5-10 fields, around 100 bytes each I really don't know what kind of a server I need to handle these requirements, my question is: what cpu/ram do I need for a dedicated server or vps? what hosting companies are able to offer this kind of dedicated server or VPS? what about cloud computing? I've researched Amazon EC2 but it seems complicated to me. And I've contacted Rackspace but strangely they said Cloudsites is not suitable for my requirements. I wonder if there is other cloud hosting company. any other alternative method? thanks very much!

• What kind of users stories should be written in the initial stages of a project?

  - by Domenic

  When just starting a project, you have nothing---no UI, no data layer, nothing in between. Thus, a single story like "users should be able to view their foos" will entail a lot of work. Once you have that story, one like "users should be able to edit their foos" is more realistic, but that first story will involve setting up a UI layer, a presentation logic layer, a domain logic layer, and a data access layer. This doesn't fit with my concept of "tasks": to me, I'd rather have something like the following "tasks": Show dummy data for a user's foos in HTML, derived from JavaScript objects. Set up a presentation logic layer, and connect the JavaScript objects to it. Set up a domain logic layer, and connect the presentation logic layer to it. Set up a data access layer, and connection the domain logic layer to it. Do all of these fall under the single "story" above? If so, I feel like stories are not a terribly useful framework in the early stages of a project. If so, that's fine---I just want to make sure I'm not missing something, since I'm really trying to learn this agile methodology as best I can.

• My mouse pointer disappears on "system surfaces" , like background picture, menus, background for all kind of system menus

  - by Siegfried

  I have an annoying problem with Ubuntu 11.10, my mouse pointer disappears on the Ubuntu surface ( not in programs like firefox, libre office ..) The mouse pointer is there, but its size is only one pixel and in the white background of e.g. "system" it is not seen at all, although with "ctrl" I can see where it should be. I have not found any place where I can change the size or colors of the mouse pointer. Can anybody help me?

• What kind of steering behaviour or logic can I use to get mobiles to surround another?

  - by Vaughan Hilts

  I'm using path finding in my game to lead a mob to another player (to pursue them). This works to get them overtop of the player, but I want them to stop slightly before their destination (so picking the penultimate node works fine). However, when multiple mobs are pursuing the mobile they sometimes "stack on top of each other". What's the best way to avoid this? I don't want to treat the mobs as opaque and blocked (because they're not, you can walk through them) but I want the mobs to have some sense of structure. Example: Imagine that each snake guided itself to me and should surround "Setsuna". Notice how both snakes have chosen to prong me? This is not a strict requirement; even being slightly offset is okay. But they should "surround" Setsuna.

• What kind of screen has the best image quality for reading/programming?

  - by EpsilonVector

  I'm thinking about buying a new laptop, and while I bought my original one oblivious to the fact that there could be different quality screens out there, after seeing the screen on my sister's netbook I realized that I might have to be cautious with my next purchase. Granted, I did not confirm that the reason my sister's screen looks the way it does is due to the screen itself and not color scheme/graphics card, but I know very little about the different screen technologies and how they differ in image quality and therefore can't really tell if wondering about it even makes sense or not. So what I'm asking is: should I be worried about screen quality? And if so, what technologies should I be looking for? How do they differ and which are the best ones? What are the different elements that determine the quality of a screen and which stats should I go for in each element? For the record, I'm not interested in opinions about screen size, but picture quality for lots of reading/coding.

• What kind of code would Kent Beck avoid unit testing?

  - by tieTYT

  I've been watching a few of the Is TDD Dead? talks on youtube, and one of the things that surprised me is Kent Beck seems to acknowledge that there are just some kinds of programs that aren't worth unit testing. For example, right here DHH says that Kent Beck is ... very happy to say "Well, TDD doesn't fit in this case, I'm just going to bail" It's frustrating to me that Kent Beck seems to acknowledge this, but nobody asks him to elaborate on it or give concrete examples. I'd like to know the situations where Kent Beck thinks TDD is a bad fit. Nobody can read his mind or speak for him, but I'm hoping he's been transparent enough through his books/tweets/whatever for someone to be able to answer. I'm not necessarily going to take what he says as gospel, but it would be useful to know that the times I've tried TDD and it just felt impossible/useless are situations that he would have bailed on it himself. Or, if it turned out he would have tested that code it'd suggest to me that I was approaching the process very wrong. I also think it would be enlightening to understand why he would bail on such projects. My opinion on why this is not a duplicate of "When is it appropriate to not unit test?" After skimming those answers I'm not satisfied. For example, look at UncleBob's answer. He doesn't even acknowledge that such a situation exists. I really think there's value in understanding Kent Beck's position, not just a general, "What's your opinion?" type of question. After all, he's the father of TDD.

• How do you decide what kind of database to use?

  - by Jason Baker

  I really dislike the name "NoSQL", because it isn't very descriptive. It tells me what the databases aren't where I'm more interested in what the databases are. I really think that this category really encompasses several categories of database. I'm just trying to get a general idea of what job each particular database is the best tool for. A few assumptions I'd like to make (and would ask you to make): Assume that you have the capability to hire any number of brilliant engineers who are equally experienced with every database technology that has ever existed. Assume you have the technical infrastructure to support any given database (including available servers and sysadmins who can support said database). Assume that each database has the best support possible for free. Assume you have 100% buy-in from management. Assume you have an infinite amount of money to throw at the problem. Now, I realize that the above assumptions eliminate a lot of valid considerations that are involved in choosing a database, but my focus is on figuring out what database is best for the job on a purely technical level. So, given the above assumptions, the question is: what jobs are each database (including both SQL and NoSQL) the best tool for and why?

• What kind of physics to choose for our arcade 3D MMO?

  - by Nick

  We're creating an action MMO using Three.js (WebGL) with an arcadish feel, and implementing physics for it has been a pain in the butt. Our game has a terrain where the character will walk on, and in the future 3D objects (a house, a tree, etc) that will have collisions. In terms of complexity, the physics engine should be like World of Warcraft. We don't need friction, bouncing behaviour or anything more complex like joints, etc. Just gravity. I have managed to implement terrain physics so far by casting a ray downwards, but it does not take into account possible 3D objects. Note that these 3D objects need to have convex collisions, so our artists create a 3D house and the player can walk inside but can't walk through the walls. How do I implement proper collision detection with 3D objects like in World of Warcraft? Do I need an advanced physics engine? I read about Physijs which looks cool, but I fear that it may be overkill to implement that for our game. Also, how does WoW do it? Do they have a separate raycasting system for the terrain? Or do they treat the terrain like any other convex mesh? A screenshot of our game so far:

• What kind of innovative non-cash financial benefits do I offer to my developers to retain them along with a competitive salary?

  - by Fanatic23

  Stock options don't make much sense, since the company's private. [It still does, if you are a facebook of sorts AND the regulatory system permits sites like secondmarket, but I digress.] I could think of some: Health benefits to parents and parents-in-laws Sponsoring a fuel-saving bike to drive to office Gift cards for occasions like completion of 1, 3, 5 years of service I really could do with more suggestions here. Appreciate 1 response per entry for ease of up-voting.

• 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.

• Is there a precedent for the license on a compiler restricting the kind of development you can use it for?

  - by Jim McKeeth

  It was recently let slip that the new EULA for Delphi XE3 will prohibit Client Server development with the Professional edition without the additional purchase of a Client Server license pack. This is not to say the Professional version will lack the features, but the license will specifically prohibit the developer from using the compiler for a specific class of development, even with 3rd party or home grown solutions. So my question is if there is a precedent of a compiler or similar creative tool prohibiting the class of work you can use it for. Specifically a commercially licensed "professional" tool like Delphi XE3. Also, would such a restriction be legally enforceable? I know there have been educational edition or starter edition tools in the past that have restricted their use for commercial purposes, but those were not sold as "professional" tools. Also I know that a lot of computing software and equipment will have a disclaimer that it is not for use in "life support equipment" or "nuclear power" but that is more of avoiding liability than prohibiting activity. Seems like I recall Microsoft putting a restriction in FrontPage that you couldn't use it to create a web site that reflected poorly on Microsoft, but they pulled that restriction before it could be tested legally.

• What kind of support does Canonical provide on a business level?

  - by blade19899

  I was wondering about the support for Ubuntu in general? If a (small/large)business is running Ubuntu, what type of issues does Canonical help out with? examples: if a business is running a windows app, via wine does canonical help out with that when a business is running software that is not installed via the software but via PPA(stable/beta) and or downloaded manually. Some examples apps libreoffice/handbrake/openshot etc... etc... does Canonical give support when those app have issues? when a business is trying to migrate from lotes notes/outlook to thunderbird? sorry if this is a bit vague, but i don't really know much about support... be as detailed possible! Thanks in advanced!!!

• T-SQL Tuesday: What kind of Bookmark are you using?

  - by Kalen Delaney

  I’m glad there is no minimum length requirement for T-SQL Tuesday blog posts , because this one will be short. I was in the classroom for almost 11 hours today, and I need to be back tomorrow morning at 7:30. Way long ago, back in SQL 2000 (or was it earlier?) when a query indicated that SQL Server was going to use a nonclustered index to get row pointers, and then look up those rows in the underlying table, the plan just had a very linear look to it. The operator that indicated going from the nonclustered...(read more)

• In what kind of variable type is the player position stored on a MMORPG such as WoW?

  - by jokoon

  I even heard J. Carmack quickly talk about it... How a software can track a player's position so accurately, being on a such huge world, without loading between zones, and on a multiplayer scale ? How is the data formatted when it passes through the netcode ? I can understand how vertices are stored into the graphic card's memory, but when it comes to synchronize the multiplayer, I can't imagine what is best.

• How can I redirect any kind of access to my site to somewhere else, except for me?

  - by Omega

  My site, www.example.com has a MyBB forum installation, and has many users constantly checking it out. I would like to make a major change to it - basically, I want to delete everything it has and start clean. However, this rebuilding process may take me hours since I need to do a lot of things. Thus, whenever an user tries to enter any part of my site (www.example.com, www.example.com/blog etc), the user will always be redirected to www.example.com/underconstruction so they can see a nice HTML site explaining the current situation. But not only that - while I am configuring my site, I need to visit it myself to make sure things do work live. So basically, it has to redirect everyone who isn't me. Is that possible in any way? I am using GoDaddy hosting.

• What kind of programmer job positions are there in professional game development? [on hold]

  - by skiwi

  I have been wondering the following since recently, seeing as I want to pursue a career in game development after university: What programmer job positions are there in professional game development? Think about AAA titles, etc. What programming language are the most commonly used ones in that area? I can think of some job aspects, like game engine, network, centralized server and artificial intelligence. I am just wondering what options I have later on, and in what programming languages I should invest right now. I am quite proficient with Java, and also wondering if that is of any help.

• What kind of projects are suited as a portfolio? [on hold]

  - by Asyx

  I was thinking about finishing up some hobby projects I used myself or am planing to use myself but I'm not sure if a future employer might be put off by them. For example, if I decided to create a custom website for an online (gaming, maybe) community instead of using an existing CMS, is it a good idea to provide a link to said community website or should I just put up the CMS and pretend like nobody actually uses it? Also, what about very specific things? I like linguistics and constructing languages. Obviously nobody wants to come up with 1000s of words so people usually use word generators or software to emulate sound shift or software to organise everything and produce dictionaries and such. Would such a project be too specific and too abstract for a portfolio or is the "he did programming work simply for enjoyment and his hobby and not just for money or grades" thing more important? It's quite an abstract hobby and most people don't even know that it's a thing and think the languages you hear in Game of Thrones, Avatar or Star Trek are just gibberish. Explaining such things to people is a pain to begin with especially if said people speak no other language. Would such things throw an employer off or is the content itself completely irrelevant? Thanks. Also, if this is not fitting for the programmers stackexchange, then please, don't close the thread right away but tell me where else to go because I got here though a closed question from stackoverflow. Thanks.

• What kind of performance issues does multiple instances of the exact same object have on a game?

  - by lggmonclar

  I'm fairly new to programming, and I've pretty much learned all the things I know on the go, while working on projects. The problem is that there some things that I just don't know where to begin searching. My question is about performance, and how can multiple instances of the same object affect it -- Specifically, I'm talking about XNA's "GraphicsDevice" class. I have it instanced on four different parts of my game, and in three of those, the object has the exact same values for all the attributes. So, in that case, should I be using the same instance of GraphicsDevice, passing it as a parameter, even if I use it in different classes? I apologize if the question seems redundant, but like I said, I've taught myself most of what I know, so there are quite a few "holes" in my learning process.

• Is the test, which touches the filenames under directory, a kind of unittest? [on hold]

  - by Chen OT

  I was told that unittest is fast and the tests which touches DB, across network, and touches FileSystem are not unittest. In one of my testcases, its input are the file names (amount about 300~400) under a specific folder. Although these input are part of file system, the execution time of this test is very fast. Should I moved this test, which is fast but touches file system, to higher level test?

• What kind of math should I be expecting in advanced programming?

  - by I_Question_Things_Deeply

  And I don't mean just space shooters and such, because in non-3D environments it's obvious that not much beyond elementary math is needed to implement. Most of the programming in 2D games is mostly going to involve basic arithmetic, algorithms for enemy AI and dimensional worlds, rotation, and maybe some Algebra as well depending on how you want to design. But I ask because I'm not really gifted with math at all. I get frustrated and worn out just by doing Pre-Algebra, so Algebra 2 and Calculus would likely be futile for me. I guess I'm not so "right-brained" when it comes down to pure numbers and math formulas, but the bad part is that I'm no art-expert either. What do you people here suppose I should do? Go along avoiding as much of the extremely difficult maths I can't fathom, or try to ease into more complex math as I excel at programming?
