I realized today that another summer had passed as the first rain in months fell here in northern California redwood country. If its fall that means that Oracle Open World is right around the corner and that tens of thousands of technology professionals will soon converge on San Francisco to fill every hotel and every corner of their minds. As in years past, team UPK will be there in force to answer questions, demo and discuss all things UPK. On Thursday, October 4, from 12:45pm to 1:45pm I along with several of my UPK teammates will be manning the User Productivity Kit Panel - Best Practices to Manage and Deploy Content.

• How to prevent one account from unlocking products on other devices using Apple StoreKit?

  - by reapz

  We are currently wrapping up a free-to-play game on iOS in which you can purchase non-consumable products. We have been discussing this case internally and are not quite sure what the best practices are as this is our first title. For example, if a user downloads our app, and makes some purchases. These can be restored should the app ever be deleted and reinstalled as long as the user uses the same Apple ID. What is to stop him from making a fake Apple account, purchasing items and then posting this account on the web allowing everyone to get the items for free? That is obviously a worst case situation. But a smaller case would be a user unlocking items for his friends. We do not want this to be an always online game but have considered doing a check on startup if there is internet available. If the currently logged in account doesn't own the products do we lock them again? Probably not because people may simply sign into the device with different Game Center logins at which point we don't want to constantly lock and unlock items. At some point we will be adding multiplayer at which point we can definately do a check with the currently logged in account. This is because A, they will be online when attempting multiplayer, and B, they will want to use their own account for multiplayer. Unfortunately we aren't quite ready for this yet. Has anyone tackled this issue. Are we overthinking here?

• How to reduce bubble-notification time in empathy?

  - by MCan

  empathy shows a bubble notification message on top right corner if a user comes online or goes offline (obviously we can change them from the preferences), but is there any way we can reduce the time for which the bubble notification remains on screen. By default it remains fro 3-4 seconds, is there any way we can change it to 1 or may be 2 seconds (I know the matter is of few seconds only but 4 seconds looks too long and I want to reduce it). Any help is welcome. Cheers.

• Using ImpactJS: How to set a publicly available variable

  - by Dave Voyles

  I'm trying to get an entity (a bullet, a grenade, and an explosive) from my player player. Specifically, I want the shootingRate of my bullet (how frequently it can be fired). How can I do this without having to call getEntityByType each time I fire this projectile? There has got to be a cleaner way from what I'm doing right now.... // Shooting var isShooting = ig.input.state('shoot'); if (isShooting && this.lastShootTimer.delta() > 0) { switch (this.activeWeapon) { case("EntityBullet"): ig.game.spawnEntity(this.activeWeapon, this.pos.x, this.pos.y - 10); var equipedWeap = ig.game.getEntitiesByType(EntityBullet); this.lastShootTimer.set(equippedWeap.shootingRate); console.log(equipedWeap.shootingRate); break; case("EntityGrenade"): ig.game.spawnEntity(this.activeWeapon, this.pos.x, this.pos.y +5); var equipedWeap = ig.game.getEntitiesByType(EntityGrenade); this.lastShootTimer.set(equipedWeap.shootingRate); console.log(EquipedWeap.shootingRate); break; case("EntityExplosiveBomb"): ig.game.spawnEntity(this.activeWeapon, this.pos.x, this.pos.y +5 ); var equipedWeap = ig.game.getEntitiesByType(EntityExplosiveBomb)[0]; this.lastShootTimer.set(equipedWeap.shootingRate); console.log(equipedWeap.shootingRate); break; } }

• XNA - Inconsistent accessibility: parameter type is less accessible than method

  - by DijkeMark

  I have a level class in which I make a new turret. I give the turret the level class as parameter. So far so good. Then in the Update function of the Turret I call a function Shoot(), which has that level parameter it got at the moment I created it. But from that moment it gives the following error: Inconsistent accessibility: parameter type 'Space_Game.Level' is less accessible than method 'Space_Game.GameObject.Shoot(Space_Game.Level, string)' All I know it has something to do with not thr right protection level or something like that. The level class: public Level(Game game, Viewport viewport) { _game = game; _viewport = viewport; _turret = new Turret(_game, "blue", this); _turret.SetPosition((_viewport.Width / 2).ToString(), (_viewport.Height / 2).ToString()); } The Turret Class: public Turret(Game game, String team, Level level) :base(game) { _team = team; _level = level; switch (_team) { case "blue": _texture = LoadResources._blue_turret.Texture; _rows = LoadResources._blue_turret.Rows; _columns = LoadResources._blue_turret.Columns; _maxFrameCounter = 10; break; default: break; } _frameCounter = 0; _currentFrame = 0; _currentFrameMultiplier = 1; } public override void Update() { base.Update(); SetRotation(); Shoot(_level, "turret"); } The Shoot Function (Which is in GameObject class. The Turret Class inherited the GameObject Class. (Am I saying that right?)): protected void Shoot(Level level, String type) { MouseState mouse = Mouse.GetState(); if (mouse.LeftButton == ButtonState.Pressed) { switch (_team) { case "blue": switch (type) { case "turret": TurretBullet _turretBullet = new TurretBullet(_game, _team); level.AddProjectile(_turretBullet); break; default: break; } break; default: break; } } } Thanks in Advance, Mark Dijkema

• Adding a new automatic number sequence

  - by Paul

  We write test case documents. In these documents, each test case is numbered. E.g. Foobar-UI-1 to Foobar-UI-23 or Foobar-Device-1 to Foobar-Device-87 I'd like to autonumber these. I don't think I want just a new numbered list format, I want something like the list of figures - where figures (or test case) can be defined anywhere in the doc with other headings and paragraphs between them, and I can insert a "List of figures" table at the beginning. So how do I do "test cases" and a "list of test-cases" table in the same way as figures work out of the box?

• Strange PHP output buffering

  - by radek-k

  PHP: header('Content-type: text/plain'); for ($i=0; $i<10; $i++){ echo "$i\r\n"; ob_flush(); flush(); sleep(1); } I tried script above on 2 different servers. Both respond numbers 0...9 in every line. In case of first server each number is received every second. In case of second server there is no output for 10 seconds and entire output is displayed at once. What might be wrong int second case? I tried various uutput control Functions but it didn't help. Set of response headers in both cases is pretty much the same: HTTP/1.1 200 OK Date: Mon, 03 Jan 2011 19:21:21 GMT Server: Apache X-Powered-By: PHP/5.2.14 Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: text/plain

• xubuntu app menu on wrong side of screen

  - by D0X

  I am using Xubuntu 12.04, with a dual monitor setup (with the nvidia driver xinerama enabled). The top panel is spanned acros the two monitors. This works quite fine, except for one thing. When I click the little Application Menu button on my left screen, the application menu opens on the top right corner of the left screen. This is quite annoying, I fiddled in the panel prefs but could not fix this. Any thoughts?

• Using Queries with Coherence Write-Behind Caches

  - by jpurdy

  Applications that use write-behind caching and wish to query the logical entity set have the option of querying the NamedCache itself or querying the database. In the former case, no particular restrictions exist beyond the limitations intrinsic to the Coherence query engine itself. In the latter case, queries may see partially committed transactions (e.g. with a parent-child relationship, the version of the parent may be different than the version of the child objects) and/or significant version skew (the query may see the current version of one object and a far older version of another object). This is consistent with "read committed" semantics, but the read skew may be far greater than would ever occur in a non-cached environment. As is usually the case, the application developer may choose to accept these limitations (with the hope that they are sufficiently infrequent), or they may choose to validate the reads (perhaps via a version flag on the objects). This also applies to situations where a third party application (such as a reporting tool) is querying the database. In many cases, the database may only be in a consistent state after the Coherence cluster has been halted.

• Why is quicksort better than other sorting algorithms in practice?

  - by Raphael

  This is a repost of a question on cs.SE by Janoma. Full credits and spoils to him or cs.SE. In a standard algorithms course we are taught that quicksort is O(n log n) on average and O(n²) in the worst case. At the same time, other sorting algorithms are studied which are O(n log n) in the worst case (like mergesort and heapsort), and even linear time in the best case (like bubblesort) but with some additional needs of memory. After a quick glance at some more running times it is natural to say that quicksort should not be as efficient as others. Also, consider that students learn in basic programming courses that recursion is not really good in general because it could use too much memory, etc. Therefore (and even though this is not a real argument), this gives the idea that quicksort might not be really good because it is a recursive algorithm. Why, then, does quicksort outperform other sorting algorithms in practice? Does it have to do with the structure of real-world data? Does it have to do with the way memory works in computers? I know that some memories are way faster than others, but I don't know if that's the real reason for this counter-intuitive performance (when compared to theoretical estimates).

• Is SEO affected negatively by having densely encoded identifiers of content in URLs?

  - by casperOne

  This isn't about where to put the id of a piece of unique content in URLs, but more about densely packing the URL (or, does it just not matter). Take for example, a hypothetical post in a blog: http://tempuri.org/123456789/seo-friendly-title The ID that uniquely identifies this is 123456789. This corresponds to a look-up and is the direct key in the underlying data store. However, I could encode that in say, hexadecimal, like so: http://tempuri.org/75bcd15/seo-friendly-title And that would be shorter. One could take it even further and have more compact encodings; since URLs are case sensitive, one could imagine an encoding that uses numbers, lowercase and uppercase letters, for a base of 62 (26 upper case + 26 lower case + 10 digits): 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz For a resulting URL of: http://tempuri.org/8M0kX/seo-friendly-title The question is, does densely packing the ID of the content (the requirement is that an ID is mandatory for look-ups) have a negative impact on SEO (and dare I ask, might it have any positive impact), or is it just not worth the time? Note that this is not for a URL shortening service, so saving space in the URL for browser limitation purposes is not an issue.

• Re-cased my computer now the power plug keeps shorting

  - by dunc

  I've just re-cased my computer. I got the new case free and thought I'd be able to swap everything over myself but apparently I've done something wrong. I'm OK with components generally but wasn't totally confident about doing this. So, my question is, when setting up a new PC or moving old components into a new case, what could I have done which causes the power cable plug to short/fuse when I plug it in?. Is this likely to be an issue with the cables from my PSU, or could it be the internal case connectors? What steps would you take to diagnose the problem? I'd rather not start again if I don't have to...! Thanks in advance,

• Sound feels to come from far in my headphones [closed]

  - by Rakesh

  I bought new headphones just yesterday. The strange thing is when I hear sound from my headphone I feel like it is coming from far away. Main problem comes in games, when I hear the footsteps of enemies and think he is on the other side of the wall while he is near to me. :D I also heard virtual haircut on youtube . I tried this with my new headphones and HTC desire S earphones. In case of HTC earphones I felt that scissors and electric razor( @ 3:04 ) is too much near to my ear but in case of the headphones I didn't felt such thing. I felt electric razor is almost 6 inches away from my ear. Have you ever encountered such problem? What can I do in this case?

• What is the main reason for ADSL modem/routers dying?

  - by ldigas

  The other day my home ADSL modem/router (dwg 684t in this case) died. A guy from the telecom company came to my place and brought another one, but he also left this one. Now, I'm interested - it didn't fall, it wasn't electrocuted - but it just doesn't work. What could be the problem? Can it be fixed? Is it worth it (in which case I would have two which is always nice)? I'm not looking for a definite opinion, just your personal advice ... (although in the end I think I'm going to archive it in the "cylinder register") What are the usual problems that occur with them? In this case, I can connect to the router, I can see its settings, I just can't connect to the Internet. With the new one everything works. Weird.

• Crash During Update Deleted ALL panels; can't open terminal; can't see icons

  So I was upgrading Ubuntu from 11.10 to 12.04 in the terminal after recovering my system from a previous crash, and then I go through a power outage during the second time trying to update. NOW, my screen is white, only the time shows up in the top right corner, no icons show up, no apps show up, AND terminal is NOT opening. I can still use the internet somehow, and ctrl + alt + F2 opens what I think is a back-up terminal? NEED HELP to recover what is lost.

• Which hard disk drive is which?

  - by djeikyb

  I want to know which hard disk drive corresponds to which device path. It's trivial to match the hard disk stats (brand, size) with the dev path, but I want more. I want to know which drive is which inside my case. What's a good way to go about getting this info? Rules: I am a lazy bum. I don't want to tear apart my server to remove all the drives, then add back one by one. A reboot is acceptable. The drives are inconveniently scrunched together in the case. All label information is hidden. The case can be opened. Most disks are SATA, so theoretically hot swappable. Unplugging cables is fair game. Bonus: For a cli only solution. I'll award answer to the best/easiest gui or cli answer, and give a bounty to the next-best answer of the other kind. Or maybe the other way around, because the bounty is worth more points.

• Acrobat Reader, and indeed all Adobe products are freezing and crashing on print

  - by 5tratus

  Everything was working fine, right up till I had to do some driver work to get my scanner to work - now I can't seem to print from any Adobe product. I click print and the program freezes, it stops responding, and in the case of Acrobat Reader, it crashes. In the case of In-design CS4, I have to stop the process in task manager, in the case of Fireworks CS3 - I think it just crashes. Printing a PDF hangs and crashes inside of Firefox and IE browsers too. My printer works and I can print from MS Word, Excel and directly by right clicking on a non-Adobe file and choosing print. But when I try it in an Adobe product. I'm running Windows 7 64-bit, my version of Adobe Reader is: 10.1.11, Windows is updated, and I don't have any unusual extensions.
