Is there a definitive reference on Pinball playfield design?

- by World Engineer

I'm looking at designing tables for Future Pinball but I'm not sure where to start as I've little background in game design per se. I've played scores of pinball tables over the years so I've a fairly good idea of what is "fun" in those terms. However, I'd like to know if there is a definitive "bible" of pinball design as far as layout and scoring/mode design goes. I've looked but there doesn't seem to be anything really coherent that I could find. Is it simply a lost art or am I missing some buried gem?

What interface does python use to implement sockets?

- by user2738698

When I programmed in python, I believe I interfaced with the transport layer using sockets. If python was programmed by humans, they must have used an interface that was "lower" than sockets, to provide us with the interface to sockets. I assume firewalls, also programmed by humans, use interfaces of lower layers in the same manner, so is there a way to access such lower layers, in terms of programming?

What happens to my domain if the TLD fails?

- by KingCrab

First question, hopefully I don't mess this up. I have recently registered some domains on the basically brand new .directory gTLD. Because of operating costs to maintain a gTLD, it is assumed that many of the hundreds being rolled out this year and next will fail. I will admit I am not very knowledgable on how the TLD process works. What exactly does a new TLD failing mean? I realize that they lose ICANN accreditation, but does that just mean that they will be no longer be sold? If the .directory were to go under, would my .directory domains be affected? I bought it from domain registrar Gandi if that helps.

Can't run the ActionBarCompat sample

- by David Miler

I am having trouble compiling and running the ActionBarCompat sample of Android 16. I have API level 16 as the build target selected, which seems to build fine, but when I try to debug these errors pop up. Of course I could change the min API level in the manifest, but what would be the point of that? I have made no changes to the sample, so how come it is not working properly? Class requires API level 14 (current min is 3): android.view.ActionProvider SimpleMenuItem.java /ActionBarCompat/src/com/example/android/actionbarcompat line 129 Android Lint Problem Class requires API level 14 (current min is 3): android.view.ActionProvider SimpleMenuItem.java /ActionBarCompat/src/com/example/android/actionbarcompat line 134 Android Lint Problem Class requires API level 14 (current min is 3): android.view.MenuItem.OnActionExpandListener SimpleMenuItem.java /ActionBarCompat/src/com/example/android/actionbarcompat line 155 Android Lint Problem I am thoroughly confused, any help would be appreciated.

Brick-level backup and restore with exchange 2007

- by V. Romanov

In the company I'm working for, we use exchange 2007 and backup it using netbackup. The backup is a daily complete backup of the information store and the direct corollary of this is that restores are hell. We need to restore the entire information store (over 80 gb), somehow merge it back with the original store, which causes problems. Alternatively, we tried using QUEST software to emulate exchange and restore mails from the emulation. However, this proved unreliable. The main problem with this entire situation is that we have to restore the whole information store and walk it through the restore process manually, and its quite absurd to be forced spend more than a day restoring even one erased email. (we have erased mail retention, but sometimes we need to restore older mail). in comparison, back in the day of XCH2003 and backupexec 12, we had complete brick level backup and restore at the push of a button. I've spoken to one of our chief sysadmins who claimed that the official response from microsoft to this issue was - "sorry guys, no brick level backup in XCH2007" which sounds ridiculous to me. Can someone shed some light on the situation? How do you backup your exchange2007 stores? Can you restore a single email quickly? A mailbox, perhaps?

IIS 8 URL Redirect on site level

- by jackncoke

I am trying to do a simple 301 perm redirect to another url in IIS 8. The end results would be if i navigated to domain2.com i would end up on domain1.com. We are moving from IIS 6 to a new server and have aprox 600+ sites that will be configured on this IIS 8 box. All of these sites run a property CMS and are looking at the same directory for source code. In IIS 6 i would just go to the Home directory tab of each site and check the box that says "Permanent Redirect" and provide a URL. With IIS 8 there is "HTTP Redirect" and this looks like it would do the trick but it is being applied to all the sites in IIS 8. Not on the site level like it use to be in IIS 6. I also looked into URL Rewriting module for IIS 8 but it seems to take rules in the style of a firewall and i am not sure if i could effectly create rules that would cater to 600+ sites. I am looking for the easiest way to have redirects on my site level so that that customers with multiple domains can have there sites redirect to there main domain for seo purposes. I feel like this was so easily achieved in IIS 6 that i must be overlooking something in the new version.

Numbered paragraphs in Word 2007

- by Kit

I have the following styles defined in Word 2007. They all have outline levels 1-6. They also correctly show up in the Table of Contents (not all, I only set the TOC up to Level 3). 1 Heading 1 1.1 Heading 2 1.1.1 Heading 3 1.1.1.1 Heading 4 1.1.1.1.1 Heading 5 1.1.1.1.1.1 Heading 6 This is what I want 1 Heading 1 1.1 Body text under Heading Level 1 1.2 Body text under Heading Level 1 2 Heading 1 2.1 Heading 2 2.1.1 Body text under Heading Level 2 2.1.2 Body text under Heading Level 2 2.1.3 Body text under Heading Level 2 2.2 Heading 2 2.2.1 Body text under Heading Level 2 2.2.2 Body text under Heading Level 2 How do I make two list sequences link to each other? Here's a {fill in the blanks} illustration: {section number} Heading 1 {section number}.{clause number} Body text under Heading Level 1 {section number}.{clause number} Body text under Heading Level 1 The example above should expand to: 1 Heading 1 1.1 Body text under Heading Level 1 1.2 Body text under Heading Level 1 Another example: {section number} Heading 1 {section number}.{subsection number} Heading 2 {section number}.{subsection number}.{clause number} Body text under Heading Level 2 {section number}.{subsection number}.{clause number} Body text under Heading Level 2 should expand to: 2 Heading 1 2.1 Heading 2 2.1.1 Body text under Heading Level 2 2.1.2 Body text under Heading Level 2 2.1.3 Body text under Heading Level 2 The numbered body text paragraphs shouldn't show up the Table of Contents. I couldn't find the right way to do that, whether in multilevel lists, fields, styles, etc. How do I do it right?

When to raise domain functional level?

- by Joel Coel

We very recently completed a project to retire two old domain controllers running Server 2003 R2. They are now replaced with shiny new 2008 R2 boxes. However, the functional level of the domain has not yet been updated for the 2008 R2 servers, just in the long-shot case of the need for a rollback to the old controllers. I expect to have the all clear to update the domain by next weekend. I also want to note that our desktop clients are still 95% Windows XP. However, we're about to start a project to update our 200 or so clients to Windows 7 before the end of the calendar year. Is there any advantage to holding the domain at the 2003 functional level while we are still supporting more Windows XP than Windows 7, especially given that some of the management stations are still XP? Update: I forgot to mention earlier that we still have a pair of windows 2000 servers (not domain controllers) that support some legacy software. I'm working to replace those, but in the meantime I need to be sure that Windows 2000 can still participate in a 2008 R2 domain.

Windows OS level file open event trigger

- by john

Colleagues, I have need to run a script/program on certain basic OS level events. In particular when a file in Windows is opened. The open may be read-only or to edit, and may be initiated by a number of means, either from windows explorer (open or ), be selected from a viewing or editing application from the native file chooser, or drag-n-drop into an editing or viewing application. Further, i need the trigger to "hold" the event from completing the action until the runtime on the program has completed. The event handler program may return a pass state, or fail state. If fail state has been returned, then the event must disallow the initially requested action. Lastly, I need to add to the file in question a property or attribute that will contain metadata that will be used by the above event trigger handler program to make a determination as to the pass/fail condition that will ultimately determine if the user is permitted to open the file. Please note that this is NOT a windows event log situation, but one at the OS level file open event. thanks very much for your help. regards, j

heroku logs --ps run showign nothing

- by Zarne Dravitzki

I have two running apps on heroku staging and production. They are near identical enviornments. (Staging has extra configs IE RailsFootnotes, Bullet gem) When I run heroku logs --ps run --app jl-staging Returns as logs like 2012-08-30T01:30:42+00:00 heroku[run.1]: Starting process with command `bundle exec rake jewellover:warn_users` This log is a Task set to run with Heroku Schedular Free. Everything Works perfect but when I do the same with heroku logs --ps run --app jl-production There are no results. No heroku[run.1] process logs. Both environments have the same scheduled tasks, albeit at different times but none the less both run scheduled tasks at specified times. Is there something im missing about heroku[run.1] processes in production env? Does heroku only keep the -ps logs for a certain amount of time? It seems to show less activity than the normal logs. Maybe only show 24hrs worth of logs rather than Last 100 logs... I need to log and debug the [run.1] process from the production env... specifically the jewellover:warn_users task. any ideas?

Player & Level class structure in 2D python console game?

- by Markus Meskanen

I'm trying to create a 2D console game, where I have a player who can freely move around in a level (~map, but map is a reserved keyword) and interfere with other objects. Levels construct out of multiple Blocks, such as player(s), rocks, etc. Here's the Block class: class Block(object): def __init__(self, x=0, y=0, char=' ', solid=False): self.x = x self.y = y self.char = char self.solid = solid As you see, each block has a position (x, y) and a character to represent the block when it's printed. Each block also has a solid attribute, defining whether it can overlap with other solids or not. (Two solid blocks cannot overlap) I've now created few subclasses from Block (Rock might be useless for now) class Rock(Block): def __init__(self, x=0, y=0): super(Rock, self).__init__(x, y, 'x', True) class Player(Block): def __init__(self, x=0, y=0): super(Player, self).__init__(x, y, 'i', True) def move_left(self, x=1): ... # How do I make sure Player wont overlap with rocks? self.x -= x And here's the Level class: class Level(object): def __init__(self, name='', blocks=None): self.name = name self.blocks = blocks or [] Only way I can think of is to store a Player instance into Level's attributes (self.player=Player(), or so) and then give Level a method: def player_move_left(self): for block in self.blocks: if block.x == self.player.x - 1 and block.solid: return False But this doesn't really make any sense, why have a Player class if it can't even be moved without Level? Imo. player should be moved by a method inside Player. Am I wrong at something here, if not, how could I implement such behavior?

Recommended textbook for machine-level programming?

- by Norman Ramsey

I'm looking at textbooks for an undergraduate course in machine-level programming. If the perfect book existed, this is what it would look like: Uses examples written in C or assembly language, or both. Covers machine-level operations such as two's-complement integer arithmetic, bitwise operations, and floating-point arithmetic. Explains how caches work and how they affect performance. Explains machine instructions or assembly instructions. Bonus if the example assembly language includes x86; triple bonus if it includes x86-64 (aka AMD64). Explains how C values and data structures are represented using hardware registers and memory. Explains how C control structures are translated into assembly language using conditional and unconditional branch instructions. Explains something about procedure calling conventions and how procedure calls are implemented at the machine level. Books I might be interested in would probably have the words "machine organization" or "computer architecture" in the title. Here are some books I'm considering but am not quite happy with: Computer Systems: A Programmer's Perspective by Randy Bryant and Dave O'Hallaron. This is quite a nice book, but it's a book for a broad, shallow course in systems programming, and it contains a great deal of material my students don't need. Also, it is just out in a second edition, which will make it expensive. Computer Organization and Design: The Hardware/Software Interface by Dave Patterson and John Hennessy. This is also a very nice book, but it contains way more information about how the hardware works than my students need. Also, the exercises look boring. Finally, it has a show-stopping bug: it is based very heavily on MIPS hardware and the use of a MIPS simulator. My students need to learn how to use DDD, and I can't see getting this to work on a simulator. Not to mention that I can't see them cross-compiling their code for the simulator, and so on and so forth. Another flaw is that the book mentions the x86 architecture only to sneer at it. I am entirely sympathetic to this point of view, but news flash! You guys lost! Write Great Code Vol I: Understanding the Machine by Randall Hyde. I haven't evaluated this book as thoroughly as the other two. It has a lot of what I need, but the translation from high-level language to assembler is deferred to Volume Two, which has mixed reviews. My students will be annoyed if I make them buy a two-volume series, even if the price of those two volumes is smaller than the price of other books. I would really welcome other suggestions of books that would help students in a class where they are to learn how C-language data structures and code are translated to machine-level data structures and code and where they learn how to think about performance, with an emphasis on the cache.

Errors trying to run MongoDB

Attempted to dual boot with Windows and now can only run Ubuntu

- by Zeusoflightning125

Very recently, I decided to attempt to dual boot Ubuntu with my already installed windows 8. Everything worked perfectly, I manually set up disk partitions (this is all on 1 hard drive), and it loaded up Ubuntu fine. HOWEVER, now when I try to load up my computer it only has 2 options in the boot menu and both just load up Windows (both were something related to hard disk). I also can only boot from legacy hard disk things. (I already only was able to aside from my USB that I installed Windows from) The Windows files are still accessible from Ubuntu, but I cannot just load Windows. There is no option to. I also don't have the 2 buttons for each operating system I was expecting. I can only select the thing to load from BIOS. So, my question is, how do I load the Windows partition on my hard drive? I'm sorry if I'm a bit clueless I am just new to both Linux and dual-booting.

Block-level deduplication on Linux

- by Benoît

NetApp provides block-level deduplication (ASIS). Do you know any filesystem (even FUSE-based) on Linux (or OpenSolaris, *BSD) that provides the same functionnality ? (I'm not interested in false deduplication like hardlinks).

How to run developer team meetings?

- by Bill Iacocca

Our team of 10 developers meet weekly. The meetings are rather boring and not particularly useful. What format/agenda do you utilize to have good meetings? We meet weekly in the conference room with pizza provided. The format is we go around the room and list the status of various tasks we are working on and discuss tasks for the next week. Managers will provide an overview of upcoming projects and priorities for the coming months and year ahead. Update The goal of these meeting is more or less - general team building, to share the knowledge of what everyone is working on, and to keep everyone aware of shifting company initiatives. It is not to formally 'hand out' work assignments (that is done via other means).

Unable to run Tor even in terminal, Vidalia exit code 127

- by Ubuntu Newb

I'm using Ubuntu 12.10 (quantal) and I recently installed Tor (32 bits) following the instructions on the Tor project's page. Then I started the script after having it extracted from the console and got this: master@ubuntu:~/tor-browser_en-US$ ./start-tor-browser Launching Tor Browser Bundle for Linux in /home/master/tor-browser_en-US ./start-tor-browser: 225: ./start-tor-browser: ./App/vidalia: not found Vidalia exited abnormally.

Win 7 Privilege Level (Run as administrator) via GP or command line

- by FinalizedFrustration

Is there a way to set the Privilege Level for legacy software via group policy or on the command line? I have some legacy software, which we unfortunately cannot move away from. This software requires administrator access. I know I can go into the Properties dialog and check "Run this program as an administrator" on every single instance on every single one of my workstations, but that gets old after the 30th install. If I had my way, we would dump this software, find some software that did what we needed, was fully compliant with Win7 security best-practices and give everyone limited user accounts... However, I am not the boss, so everyone gets administrator accounts. Given that, I suppose I could just tell everyone to open the context menu and choose "Run as administrator", but we have some very, very, VERY low-tech users, and half of them might just choose "Delete" instead. Anyone know of a way to set this option on the command line? or better yet, through Group Policy?
