• Cliché monsters to populate a steampunk fantasy setting dwarven dungeon?

  - by Alexander Gladysh

  I'm looking for a list of cliché monsters for a steampunk computer game (assume one kind or another of casual rogue-like RPG), to populate lower levels of ancient dwarven-built dungeons. Dwarves are a technology/science race in the setting I am aiming for. The world is a low-magic one. I'm stuck after listing various mechanical golems, gigantic spiders (every dungeon must have some of them!), and maybe a mechanical barlog as a megaboss. What would player expect? What are the key cultural references for such setting? I know a couple of games with suitable steampunk dwarves, but none are detailed enough in the underworld monsters area. Please point me in the right direction. (If you have a single funny monster suggestion, please mention it in comments, not in answer. ;-) )

• Weird symbols on Mac

  - by Rich Bradshaw

  Since I've had my mac, I keep seeing this weird symbol. Till today, it had been only in the place of bullet points in OpenOffice.org. The first pictures shows this in a .doc file created on a Windows system. I thought nothing of it - just an annoyance. It appears no matter what the font. Real bullets appear if I delete the text and insert a bulletted list using the toolbar. Then, today I noticed in in iTunes - which seemed strange. Image 3 is a zoom of the character. It says on it: Private Use E000 F8FF. What is it (unicode related?), and how do I get the bullets working properly? Edit: The plot thickens... If I boot in Safe Mode, the symbols look like little snap boards like you'd have at the beginning of filming a scene in a film...

• Clutter for game GUI

  - by tjameson

  I'm pretty new to game development, having only written a simple 3d game for a class project, but I'd like to get started on a bigger project. I'm writing an MMORPG to run in both the browser (WebGL) and natively (OpenGL ES 2). In choosing a GUI toolkit, I'm trying to find a style that work work natively and would be simple to emulate in WebGL. I am considering using D or Go for writing my game, so interfacing with C++ libraries will be difficult, if not impossible. Of course, the language isn't the end goal here, so if using C++ will save considerable time, I'll bite the bullet and use that. In order to reduce the amount of code I'll have to write for the browser, I'm considering using something simple like Clutter for basic abstractions, which I think will be pretty easy to emulate (layered canvases maybe?). Does anyone have experience using Clutter for a 3d game? Note: I haven't used any game development libraries, and I only have limited experience with GUI libraries. I do have HTML+CSS experience, so maybe librocket is a viable solution?

• Virtual hosting

  - by H3llGhost

  Hello, I want to use domains like xxx.abc.domain.tld. The xxx is my folder to access. I tried it with the rewrite rules, but I can't get it working, because I don't know how to get the part xxx from the SERVER_NAME into my RewriteRule. This was my try: UseCanonicalName Off # include the IP address in the logs so they may be split LogFormat "%A %h %l %u %t \"%r\" %s %b" vcommon CustomLog /var/log/apache2/vaccess.log vcommon RewriteEngine On # a ServerName derived from a Host: header may be any case at all RewriteMap lowercase int:tolower ## deal with normal documents first: # do the magic RewriteCond ${lowercase:%{SERVER_NAME}} ^.+\.abc\.domain\.tld$ RewriteRule ^(.*)$ /var/www/abc.domain.tld/[xxx-part]/$1 [L] Perhaps there is a better solution. In generally I want to create a dynamic login system with mod_auth_mysql and for each xxx is a seperate user database. I would prefer the domain/address syntax abc.domain.tld/xxx, but I don't know how to realize it. Thanks for any advices.

• Semantic coupling vs. large class

  - by user106587

  I have hardware I communicate with via TCP. This hardware accepts ~40 different commands/requests with about 20 different responses. I've created a HardwareProxy class which has a TcpClient to send and receive data. I didn't like the idea of having 40 different methods to send the commands/requests, so I started down the path of having a single SendCommand method which takes an ICommand and returns an IResponse, this results in 40 different SpecificCommand classes. The problem is this requires semantic coupling, i.e. the method that invokes SendCommand receives an IResponse which it has to downcast to SpecificResponse, I use a future map which I believe ensures the appropriate SpecificResponse, but I get the impression this code smells. Besides the semantic coupling, ICommand and IResponse are essentially empty abstract classes (Marker Interfaces) and this seems suspicious to me. If I go with the 40 methods I don't think I have broken the single responisbility principle as the responsibility of the HardwareProxy class is to act as the hardware, which has all of these commands. This route is just ugly, plus I'd like to have Asynchronous versions, so there'd be about 80 methods. Is it better to bite the bullet and have a large class, accept the coupling and MarkerInterfaces for a smaller soultuion, or am I missing a better way? Thanks.

• Offshoring: does it ever work?

  - by DanSingerman

  I know there has been a fair amount of discussion on here about outsourcing/offshoring, and the general opinion seems to be that at best it is difficult, and at worst it fails. I have direct experience of offshoring myself; a previous company where I was a dev manager wanted to send some development offshore, and we ran a pilot scheme to see how well it would work. Of course it was a complete failure, although it is not completely clear to me whether this was down to the offshore devs being less talented, the process, or other factors (no doubt it was really a combination). I can see as a business how offshoring looks attractive (much lower day rate), but as far as I can see, the only way it could possibly work is if you do exceptionally detailed design up front, with incredibly detailed specifications; and by the time you have invested in producing that, you have probably spent as nearly as much as if you had written the actual code locally (which I think is an instance of No Silver Bullet) So, what I want to know is, does anyone here have any experience of offshoring actually working ever? Especially if there are any success stories of it working in a semi-agile way? I know there are developers here from all over the World; has anyone worked on an offshore project they consider successful?

• Mechanics of reasoning during programming interviews

  - by user129506

  This is not the usual "I don't want to write code during an interview", in this question the assumption is that I need to write code during an interview (think about the level of rewriting the quicksort or mergesort from scratch) I know how the algorithm work or I have a basic idea of how I should start working from there, i.e. I don't remember the algorithm by heart I noticed that even on a whiteboard, I always end up writing bugged code or code that doesn't compile. If there's a typo, whatever I usually live with that.. but when there's a crash due to some uncaught particular case I end up losing confidence in my skills. I realize that perhaps interviewers might want to look at how I write code and/or how I solve problems rather than proof-compiling my whiteboard code, but I'd like to ask how should I approach the above problem in mental terms, i.e. what mental steps should I follow when writing code for an interview with the two bullet points above. There must be a unique and agreed series of steps I should follow to avoid getting stuck/caught into particular exception cases (limit cases) that might end up wasting my time and my energies rather than focusing on the overall algorithm for the general case. I hope I made my point clear

• Ubuntu won't wake after pm-suspend

  - by Matus

  i have ubuntu 12.04 on my Zotac AD-02. Problem is when i run pm-suspend. zotac goes to sleep (it shows red led, and green light is flashing) but when i send magic packet to WOL it hangs ... it stops flashing and LED is green as its turned on but SSH wont run and it won't react to mouse or anything. I've read that sometimes it has something to do with graphics. It is mainly for DLNA and PLEX so i don't use any graphic component so if there is the problem tell me how to disable it :) is there some log or anything i can post? im fairly good at bash but not at all in ubuntu or debian. so i can't find any log. Thanks EDIT: here is lscpi if it helps

• Strategies for avoiding SQL in your Controllers... or how many methods should I have in my Models?

  - by Keith Palmer

  So a situation I run into reasonably often is one where my models start to either: Grow into monsters with tons and tons of methods OR Allow you to pass pieces of SQL to them, so that they are flexible enough to not require a million different methods For example, say we have a "widget" model. We start with some basic methods: get($id) insert($record) update($id, $record) delete($id) getList() // get a list of Widgets That's all fine and dandy, but then we need some reporting: listCreatedBetween($start_date, $end_date) listPurchasedBetween($start_date, $end_date) listOfPending() And then the reporting starts to get complex: listPendingCreatedBetween($start_date, $end_date) listForCustomer($customer_id) listPendingCreatedBetweenForCustomer($customer_id, $start_date, $end_date) You can see where this is growing... eventually we have so many specific query requirements that I either need to implement tons and tons of methods, or some sort of "query" object that I can pass to a single -query(query $query) method... ... or just bite the bullet, and start doing something like this: list = MyModel-query(" start_date X AND end_date < Y AND pending = 1 AND customer_id = Z ") There's a certain appeal to just having one method like that instead of 50 million other more specific methods... but it feels "wrong" sometimes to stuff a pile of what's basically SQL into the controller. Is there a "right" way to handle situations like this? Does it seem acceptable to be stuffing queries like that into a generic -query() method? Are there better strategies?

• Non-ECC memory with ZFS: a stupid idea?

  - by iconoclast

  I'm the proud new owner of an HP Proliant Microserver N40L, and planning to upgrade the (obviously paltry 2 GB of) memory to the maximum of 16 GB. (Theoretically 8 GB is the limit, but empirically 16 GB has been shown to work.) Some guides advise that ECC memory is not that important, but I'm not so sure I believe this. I've installed FreeNAS and am planning to add ZFS volumes as soon as my new hard drives arrive. Would it be stupid to skimp and get non-ECC memory for a ZFS-based NAS? If it's necessary, then I'll bite the bullet, but if it's just paranoia, then I'll probably skip it.

• If my URL's are static, but then parsed by Javascript, does that make it crawlable?

  - by Talasan Nicholson

  Lets say I have a link: <a href="/about/">About Us</a> But in Javascript [or jQuery] catches it and then adds the hash based off of the href attribute: $('a').click(function(e) { e.preventDefault(); // Extremely oversimplified.. window.location.hash = $(this).attr('href'); }); And then we use a hashchange event to do the general 'magic' of Ajax requests. This allows for the actual href to be seen by crawlers, but gives client-side users with JS enabled an ajax-based website. Does this 'help' the general SEO issues that come along with hashtags? I know hashbangs are 'ok', but afaik they aren't reliable?

• DirectCompute information

  - by N0xus

  I've been trying to make use of the GPU as part of a project of mine. I've looked into both CUDA and OpenCL, but the lack of information showing you how to introduce these into a project is shocking. Even their dedicated forum groups are dead. So now, I'm looking into DirectCompute. From what I can tell, it's simply a new type of shader file that makes use of HLSL. My question is this, does my program (aside from being DirectX 10 / 11 ) need its structure changed? I mean, is it simply a case of creating the CS file, setting in the project like I would any other shader, and watch the magic happen? Any information on this would be appreciated.

• Design practice for securing data inside Azure SQL

  - by Sid

  Update: I'm looking for a specific design practice as we try to build-our-own database encryption. Azure SQL doesn't support many of the encryption features found in SQL Server (Table and Column encryption). We need to store some sensitive information that needs to be encrypted and we've rolled our own using AesCryptoServiceProvider to encrypt/decrypt data to/from the database. This solves the immediate issue (no cleartext in db) but poses other problems like Key rotation (we have to roll our own code for this, walking through the db converting old cipher text into new cipher text) metadata mapping of which tables and which columns are encrypted. This is simple when it's just couple of columns (send an email to all devs/document) but that quickly gets out of hand ... So, what is the best practice for doing application level encryption into a database that doesn't support encryption? In particular, what is a good design to solve the above two bullet points? If you had specific schema additions would love it if you could give details ("Have a NVARCHAR(max) column to store the cipher metadata as JSON" or a SQL script/commands). If someone would like to recommend a library, I'd be happy to stay away from "DIY" too. Before going too deep - I assume there isn't any way I can add encryption support to Azure by creating a stored procedure, right?

• connect to xbox using Windows Media Center

  - by waspinator

  Is there any software available for ubuntu that can emulate Windows Media Center for connecting a computer to an xbox? I tried following the xbox wizard, but it says that I need Windows. I just want to be able to choose to show pictures, play music or video on my tv through my xbox instead of my computer. I can currently do something similar using my Samsung phone and wireless TV using AllShare. I just choose which video I want to play and where and it works like magic. The TV my xbox is connected to though doesn't have wireless so I was hoping to use the xbox for similar functionality. Thanks

• nfs mountpoint named ``share'' breaks ls and man

  - by freddyb

  I mounted a nfs server to ~/share. This works fine as long as I'm at home, where the nfs share is in reach. Whenver I'm not, this seems to break access to all manpages. Using man (or ls in my homedir) waits forever. Checking with strace reveals that they try to access the folder called share. Unmounting fails too. Even with -l (lazy) and -f (force). I am asking for three things here: Is ``share'' a magic name? Does something like MANPATH exist, which I should avoid? How do I unmount without rebooting? (I already commented the share out in fstab) What would you suggest me to do, to have network/position based mounting of NFS shares?

• How to syncronize two animations without delays

  - by GeKi

  I have one character idle animation running inside a game in a loop, over and over again. A a certain time I trigger another animation to be played, for the same character. The second animation won't play immediately, as will be a discontinuity in my character animation. First I wait for the idle animation to finish and then I play my second animation. Now I have a smooth, continuous animation, BUT I have introduced a delay between my action and character animation. If I play the second animation right away as it is triggered, the character animation won't be continuous and smooth. I was thinking on breaking the idle animation in small pieces and also to have the same number of second action animations to match the last frame of the idle pieces. This won't solve the delay completely, only will minimize it a bit. So it's a magic formula of how can I get rid of this delay? Thanks.

• How to prevent overlapping of gunshot sounds when using fast-firing weapons

  - by G3tinmybelly

  So I am now trying to find sounds for my guns but when I grab a gun sound effect and play it in my game a lot of the sounds are either terrible sounding or have this horrible echoing effect because as a gun shoots sometimes the previous sound is playing still. public void shoot(float x, float y, float direction){ if(empty){ PlayHUD.message = "No more bullets!"; return; } if(reloading){ return; } if(System.currentTimeMillis() - lastShot < fireRate){ //AssetsLoader.lmgSound.stop(); return; } float dx = (float) (-13 * Math.cos(direction) + 75 * Math.sin(direction)); float dy = (float) (-14 * -Math.sin(direction) + 75 * Math.cos(direction)); float dx1 = (float) (-13 * Math.cos(direction) + 75 * Math.sin(direction)); float dy1 = (float) (-14 * -Math.sin(direction) + 75 * Math.cos(direction)); PlayState.effects.add(new MuzzleFlashEffect(x + dx1, y + dy1, (float) Math.toDegrees(-direction))); PlayState.projectiles.add(new Bullet(this, x + dx, y + dy, (float) (direction + (Math.toRadians(MathUtils.random(-accuracy, accuracy)))))); if(OptionState.soundOn){ AssetsLoader.lmgSound.play(OptionState.volume); } bulletsInClip--; lastShot = System.currentTimeMillis(); } Here is the code for where the sound plays. Every time this method is called the sound is called but it happens so often in this case that there is this terrible echoing. Any idea on how to fix this?

• Choosing the correct network protocol for my type of game (its Wc3 Warlock style)

  - by Moritz

  I need to code a little game for a school project. The type of the game is like the Warcraft 3 map "Warlock", if anyone doesnt know it, here is a short description: up to ten players spawn into an arena filled with lava, the goal of each player is to push the other players into the lava with spells (basically variations of missiles, aoe nukes, moba spells etc) http://www.youtube.com/watch?v=c3PoO-gcJik&feature=related we need to provide multiplayer-support over the internet, for that reason I am looking for the best network protocol for this type of game (udp, tcp, lock step, client-server...) what the requirements are: - same/stable simulation on all clients - up to ten players - up to ~100 missiles on the field - very low latency since its reaction based (i dont know the method wc3 used, but it was playable with the old servers) what would be nice (if even possible, since the traffic might be too big): - support for soft bodies over the network (with bullet physics), but this is no real requirement I read several articles about the lock step method used for RTS games, this seems to be great, but does it fit for real-time action games too (ping-related)? If anyone has run into the same problems/questions like me, I would be very happy about any help

• Removing 'bundled' software to make a slow laptop faster?

  - by spdegabrielle

  My brother-in-law has a cheap HP laptop used by his kids for schoolwork. It had got into a bit of a state and was running slowly with some dubious software. I removed a bunch of stuff that had been installed, that was obviously not required (three different driver scanners!), had been downloaded in error or looked like malware. I also disabled as many 'start on login' apps as I could and removed AVG replacing it with MSE. (AVG is uninstalled and replaced with MSE after failing to detect malware) What remains is a significant quantity of bundled HP and 'nero backup' software, including a HP restore utility (apparently something like the osx hidden partition restore), the trackpad driver. is there anything else I can do to breath a little more life into the old 'celeron' laptop? Should I bit the bullet and just put win8 on it? Will the trackpad still work?

• Installing nVidia drivers for Quadro FX 880M on 10.10 caused shutdown/startup issues.

  - by Chantz

  So I was facing weird graphics drivers issues due to the default nouveau drivers that came installed with Ubuntu 10.10 hence I installed the latest nVidia graphics drivers & I the weird graphics issues stopped happening. So far so good, but when I tried to shut down the laptop it got stuck at the window with text 15, shutting down... modem-manager: Caught signal 15, shutting down... init: Disconnected from system us init: dbus main process (1107) killed by TERM signal And this happens .everytime.without.fail. I tried updating the kernel and any/all drivers through update manager but it stil happens. Not only this even the startup screen is totally screwed up. It just displays Ubuntu 10.10 in text with 3 dots. But that is acceptable. To power cycle down the laptop each and everytime for shutdown is not cool. Same goes for when I try to restart. Interesting thing is if I try to shutdown the laptop when I am on the login screen it does so without any problems. I googled & many people seem to face the same issue but I couldn't find any silver bullet hoping to find one here.

• Low-level 10-finger multi-touch data on the Nexus 7?

  - by Croad Langshan

  I'm considering getting a Nexus 7 to do some multi-touch development on Ubuntu in the run-up to 13.04 (i.e., now :-). What APIs, /dev files, or protocols are available, or could be made available with not too much work on my part? What data is available from the device? The data I want to get my hands on is -- if I can -- the same as I get from /dev/uinput/event* from an Apple Magic Trackpad, viz: positions of all touches (could be as many as 10 simultaneous touches, but much more typically 6 or fewer) their size/pressure (in both x and y directions) their angle their identity -- i.e. an integer that is somewhat reliably preserved across touch events, for as long as a finger doesn't lift off the surface Not all of this data is essential -- but the more of it there is, the merrier.

When I click on it, though, my web browser (Iceweasel 12) gives me a prompt to download the file, instead of just displaying it: Is there any magic I can add to the web page, or as a header to the file (that will still allow it to be included by a .c compiled with gcc), to get the .h file to be displayed in the web browser?
