• Have rTorrent to move .torrent files

  - by David Alvares

  I am running rTorrent 0.9.2 and have configured it to move completed torrents to a different folder with this configuration line: system.method.set_key = event.download.finished,move_complete,"d.set_directory=~/done/;execute=mv,-u,$d.get_base_path=,~/done/" This is working fine, but I would like it to also move the .torrent file that it creates (from a magnet link into the session directory) into this done directory with the same name as the torrent and a .torrent extension. I tried adding another cp command, but I can not seem to figure out which variable ($d.get_hash did not work) stores the torrent's hash (which is what the .torrent files are named in the session directory). Is there a way to do this with rTorrent, if so how?

• Windows 2008 R2 Scheduled Task Not Running With Admin Privileges even if granted?

  - by j.rightly

  I have a scheduled task that is running as USER. I have checked the box "Run with highest privileges" in the scheduled task properties. The task is a powershell script that, among other things, reboots the system. The script executes and runs normally, but as a scheduled task, it fails to reboot the system. Here is the kicker: When I manually run the script as USER using the exact same command line as what's in the scheduled task, the script still runs but this time it actually reboots the system. I have UAC disabled and USER is a member of the local Admins group. The local Admins group has the right to shut down the system. Nothing in the event logs offers any clues. Why would the same script running under the same credentials work interactively but not as a scheduled task? UPDATE: This is too weird. When the task ran on schedule, everything worked normally.

• How to temporarily stop web pages intercepting a right-click?

  - by callum

  Some websites like Google Drive intercept right-clicks and provide their own context menu. This is usually what I want, but sometimes I still want to do a normal, native browser right-click. Is there any modifier key or something like that to make it so a right-click doesn't trigger a click event on the web page, so it can't show it's context menu? I want to do this per-click, not by changing a setting somewhere. If there are different techniques depending on browser/OS, please list them.

• IIS 8 Random 503 service unavailable

  - by Ivo

  We migrated a busy website to Windows Server 2012 with IIS 8. The website randomly gives the error "503 service unavailable" after an user presses F5 the error is gone again. The website is build in ASP.NET MVC 3. The website runs on one application pool, with default settings There are around 500 to 900 concurrent users on the website during the day, and the error happens more often when there are more 650 users. The CPU and the memory use on the server is stable. There is nothing about the 503 errors in the application log, the IIS log and the event log. Does anyone has any clue what the problem can be or how we can trace the the problem?

• HDD vanished after wakeup from standby

  - by Sam

  In my computer I got two hard drives: One 80GB Intel X25 Postville SSD for the system and a 1,5TB Sata HDD for data. When I put the system into standby, and wake it up again, roundabout 50% of the time the 1,5TB HDD is not found. It just vanished from the system (wreaking havok to all programs running which had open files on it). Even going into the system management and refreshing the drives does not find the lost HDD. There are no messages about this in the event log. After a warm reboot the hdd is found again, just like it should. The system is a Shuttle SP35P2 Pro with 8GB Ram and DualCore CPU, OS is Windows 7 Ultimate. I even set up the OS anew, didn't help. Any ideas what might cause this? How to debug, or maybe even fix it?

• HTML5 point and click adventure game code structure with CreateJS

  - by user1612686

  I'm a programming beginner. I made a tiny one scene point and click adventure game to try to understand simple game logic and came up with this: CreateJS features prototypes for creating bitmap images, sprites and sounds objects. I create them and define their properties in a corresponding function (for example images(); spritesheets(), sounds()...). I then create functions for each animation sequence and "game level" functions, which handle user interactions and play the according animations and sounds for a certain event (when the level is complete, the current level function calls the next level function). And I end up with quite the mess. What would be the "standard (if something like that exists)" OOP approach to structure simple game data and interactions like that? I thought about making game.images, game.sprites, game.sounds objects, which contain all the game data with its properties using CreateJS constructors. game.spriteAnimations and game.tweenAnimations objects for sprite animations and tweens and a game.levelN object, which communicates with a game.interaction object, processing user interaction. Does this make any sense? How do you structure your simple game code? Thanks in advance!

• Runaway version store in tempdb

  - by DavidWimbush

  Today was really a new one. I got back from a week off and found our main production server's tempdb had gone from its usual 200MB to 36GB. Ironically I spent Friday at the most excellent SQLBits VI and one of the sessions I attended was Christian Bolton talking about tempdb issues - including runaway tempdb databases. How just-in-time was that?! I looked into the file growth history and it looks like the problem started when my index maintenance job was chosen as the deadlock victim. (Funny how they almost make it sound like you've won something.) That left tempdb pretty big but for some reason it grew several more times. And since I'd left the file growth at the default 10% (aaargh!) the worse it got the worse it got. The last regrowth event was 2.6GB. Good job I've got Instant Initialization on. Since the Disk Usage report showed it was 99% unallocated I went into the Shrink Files dialogue which helpfully informed me the data file was 250MB.  I'm afraid I've got a life (allegedly) so I restarted the SQL Server service and then immediately ran a script to make the initial size bigger and change the file growth to a number of MB. The script complained that the size was smaller than the current size. Within seconds! WTF? Now I had to find out what was using so much of it. By using the DMV sys.dm_db_file_space_usage I found the problem was in the version store, and using the DMV sys.dm_db_task_space_usage and the Top Transactions by Age report I found that the culprit was a 3rd party database where I had turned on read_committed_snapshot and then not bothered to monitor things properly. Just because something has always worked before doesn't mean it will work in every future case. This application had an implicit transaction that had been running for over 2 hours.

• Disable (or switch off) a network interface on windows but keep the "plug and play"

  - by Leandro

  I'm looking for a good workaround to do this on Windows 7 and Windows XP: Disable or make ineffective the network interface (ETH, WIFI, any NIC). If the user connect his ETH cable, the network interface enable again. Important Notes to take care: I'm working with wmic on Win7 (through the command line) I'm working with devcon on WinXP (through the command line) I'm specifically working with the .NET Framework 2.0 on C# but this is just for informational purposes. I know that an event won't help me to detect it (if there is a way or workaround to do this I don't know it). The real problem is that when I disable the NIC, I can't know if the user connects his cable or has a wired network. This is why I am looking for a workaround. I'll treat suggestions as answers if no direct answer exists. I'll provide any extra detail necessary.

• HTTP, JSON, JavaScript, Map and Reduce built-in to MySQL

  - by Bertrand Matthelié

  Oracle MySQL Engineer Ulf Wendel delivered yesterday a talk about his Proof of Concept at the International PHP Conference in Berlin entitled: “HTTP, JSON, JavaScript, Map and Reduce built-in to MySQL - make it happen, today.” The presentation has been featured today on the home page of SlideShare, both into the “Hot on Facebook” and “Hot on Twitter” sections. Well done, Ulf! Especially just before the wedding…:) Presentation abstract: See how a MySQL Server plugin can be developed to build all this into MySQL. A new direct wire between MySQL and client-side JavaScript is created. MySQL speaks HTTP, replies JSON and offers server-side JavaScript. Server-side JavaScript gets access to MySQL data and does Map&Reduce of JSON documents stored in MySQL. Fast? 2-4x faster than proxing client-side JavaScript request through PHP/Apache. Reasonable results... Slides available here. And, talking about innovation… today is Oracle’s MySQL Innovation Day, you can still attend the event online. Register Now, it starts at 9.00 am PT.

• Apache VERY high page load time

  - by Aaron Waller

  My Drupal 6 site has been running smoothly for years but recently has experienced intermittent periods of extreme slowness (10-60 sec page loads). Several hours of slowness followed by hours of normal (4-6 sec) page loads. The page always loads with no error, just sometimes takes forever. My setup: Windows Server 2003 Apache/2.2.15 (Win32) Jrun/4.0 PHP 5 MySql 5.1 Drupal 6 Cold fusion 9 Vmware virtual environment DMZ behind a corporate firewall Traffic: 1-3 hits/sec avg Troubleshooting No applicable errors in apache error log No errors in drupal event log Drupal devel module shows 242 queries in 366.23 milliseconds,page execution time 2069.62 ms. (So it looks like queries and php scripts are not the problem) NO unusually high CPU, memory, or disk IO Cold fusion apps, and other static pages outside of drupal also load slow webpagetest.org test shows very high time-to-first-byte The problem seems to be with Apache responding to requests, but previously I've only seen this behavior under 100% cpu load. Judging solely by resource monitoring, it looks as though very little is going on. Here is the kicker - roughly half of the site's access comes from our LAN, but if I disable the firewall rule and block access from outside of our network, internal (LAN) access (1000+ devices) is speedy. But as soon as outside access is restored the site is crippled. Apache config? Crawlers/bots? Attackers? I'm at the end of my rope, where should I be looking to determine where the problem lies?

• windows 7 crash during hibernation

  - by Andrew Fforts

  At times, when I hibernate my Dell Latitude e6400 with Windows 7 (64 bit), the laptop screen goes black as it should, but then it takes several minutes before it powers down. Then, when I attempt to "resume," Windows boots up from a fresh startup, with all my work lost, and tells me that it's recovered from a serious error. What can I do to resolve this problem? Other background info: -I got a new hard drive with plenty of space about a year ago; I only use a small fraction of that space. This sometimes happens when I don't have any programs running at all. If it's relevant, I do have Dropbox and OneDrive running in the background, though. -The problem usually occurs when I hibernate just after I unplug from an external monitor to bring my laptop home, but I believe it happens at other times, too. Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.256.4 Locale ID: 1033 Additional information about the problem: BCCode: 1000009f BCP1: 0000000000000004 BCP2: 0000000000000258 BCP3: FFFFFA80036DEB50 BCP4: FFFFF80000B9C510 OS Version: 6_1_7601 Service Pack: 1_0 Product: 256_1

• How to deal with OpenGL and Fullscreen on OS X

  - by Armin Ronacher

  I do most of my development on OS X and for my current game project this is my target environment. However when I play games I play on Windows. As a windows gamer I am used to Alt+Tab switching from within the game to the last application that was open. On OS X I currently can't find either a game that supports that nor can I find a way to make it possible. My current project is based on SDL 1.3 and I can see that cmd+tab is a sequence that is sent directly to my application and not intercepted by the operating system. Now my first attempt was to hide the rendering window on cmd+tab which certainly works, but has the disadvantage that a hidden OpenGL window in SDL cannot be restored when the user tabs back to the application. First of all, there is no event fired for that or I can't find it, secondly the core problem is that when that application window is hidden, my game is still the active application, just that the window disappeared. That is incredible annoying. Any ideas how to approximate the windows / linux behavior for alt+tab?

• Election 2012: Twitter Breaks Records with MySQL

  - by Bertrand Matthelié

  Twitter VP of Infrastructure Operations Engineering Mazen Rawashdeh shared news and numbers yesterday on his blog: "Last night, the world tuned in to Twitter to share the election results as U.S. voters chose a president and settled many other campaigns. Throughout the day, people sent more than 31 million election-related Tweets (which contained certain key terms and relevant hashtags). And as results rolled in, we tracked the surge in election-related Tweets at 327,452 Tweets per minute (TPM). These numbers reflect the largest election-related Twitter conversation during our 6 years of existence, though they don’t capture the total volume of all Tweets yesterday." "Last night, Twitter averaged about 9,965 TPS from 8:11pm to 9:11pm PT, with a one-second peak of 15,107 TPS at 8:20pm PT and a one-minute peak of 874,560 TPM. Seeing a sustained peak over the course of an entire event is a change from the way people have previously turned to Twitter during live events. Now, rather than brief spikes, we are seeing sustained peaks for hours." Congrats to Jeremy Cole, Davi Arnaut and the rest of the team at Twitter for their excellent work! Jeremy recently held a keynote presentation at MySQL Connect describing how MySQL powers Twitter, and why they chose and continue to rely on MySQL for their operations. You can watch the presentation here. He also went into more details during another presentation later that day and you can access the slides here. Below a couple of tweets from Jeremy after what have surely been hectic days...  Keep up the good work guys!

• Soft 404 error on redirected outbound links

  - by Techlands

  I have a redirect script on my site which sends visitors to an affiliate site. However in the last month I've noticed that Google webmaster tools is reporting my outbound links as a 404 error. Here is the breakdown on how its setup: My outbound links are coded like this: <a href="/f/c123" rel="nofollow" target="_blank">Link Title</a> My redirect script will then perform a 302 redirect to the affiliate link Originally I had the affiliate links (CJ) directly in the HTML, however I noticed over time that this had some impact on my sites traffic. So I changed them to a redirect script and my traffic returned. This seemed to work with no issues for over 1 year but now I'm getting soft 404 errors in Google webmaster tools. I did try adding a rule in my robots.txt to block any links starting with /f/ but I'm not sure if this will help or Google will still report soft 404 errors. I am considering as possible options to change the a tag to a button tag and use an onclick event to load the link.

• JavaServer Faces 2.0 for the Cloud

  - by Janice J. Heiss

  A new article now up on otn/java by Deepak Vohra titled “JSF 2.0 for the Cloud, Part One,” shows how JavaServer Faces 2.0 provides features ideally suited for the virtualized computing resources of the cloud. The article focuses on @ManagedBean annotation, implicit navigation, and resource handling. Vohra illustrates how the container-based model found in Java EE 7, which allows portable applications to target single machines as well as large clusters, is well suited to the cloud architecture. From the article-- “Cloud services might not have been a factor when JavaServer Faces 2.0 (JSF 2.0) was developed, but JSF 2.0 provides features ideally suited for the cloud, for example:•    The path-based resource handling in JSF 2.0 makes handling virtualized resources much easier and provides scalability with composite components.•    REST-style GET requests and bookmarkable URLs in JSF 2.0 support the cloud architecture. Representational State Transfer (REST) software architecture is based on transferring the representation of resources identified by URIs. A RESTful resource or service is made available as a URI path. Resources can be accessed in various formats, such as XML, HTML, plain text, PDF, JPEG, and JSON, among others. REST offers the advantages of being simple, lightweight, and fast.•    Ajax support in JSF 2.0 is integrable with Software as a Service (SaaS) by providing interactive browser-based Web applications.” In Part Two of the series, Vohra will examine features such as Ajax support, view parameters, preemptive navigation, event handling, and bookmarkable URLs.Have a look at the article here.

• Mandatory look back at 2010

  - by Bertrand Le Roy

  Yeah, it's one of those posts, sorry. First, the mildly depressing: the most popular post on this blog this year with 47,000 hits was a post from last year about a fix to a bug in ASP.NET. A content-less post except for that link to the KB article that people should have found by going directly to the support site in the first place. Then, the really depressing: the second most popular post this year with 34,000 hits was a post from 2005 about how to display message boxes on a web page. I mean come on. This was kind of fun five years ago and it did solve one of the most common n00b mistakes VB programmers trying to move to the web were making. But come on, we've traveled about 4.7 billion miles around the Earth since then. Do people still do that kind of stuff? I should probably put a big red banner on top of this post. Oh [supernatural entity of your choice]. Hand me that gun, please. Third most popular post with 24,000 hits is from 2004. It's about how to set a session variable before redirecting. That problem has been fixed a long time ago. Oh well. Fourth most popular post. 21,000 hits. 2007. How to work around a stupid bug in ASP.NET Ajax 1.0. Fixed in ASP.NET 3.5? ASP.NET Ajax 1.0? Need I say more? The fifth one (20,000 hits) is an old post as well but I'm kind of fond of it: it's about that photo album handler I've been organically growing for a few years. It reminds me that I need to refresh it and make a new release. Good SEO title too. Back to insanity with the sixth one (16,000) that's about working around a bug in IE6. IE6. Please just refuse to pander to that browser any more. It's about time. Let's move on, please. Actually, the first post from 2010 is 15th in the list. We have a trio of these actually with server-side image resizing and FluentPath. So what happened? Well, I like the ad money, but not to the point that I'm going to write my stuff to inflate it. Actually I think if I tried I would fail miserably (I mean, I would fail worse). What really happened this year was new stuff: Orchard, FluentPath and the stuff with the Netduino. That stuff needs time to get off the ground but my hope is that it's going to be useful in the long run and that five years from now I'll be lamenting on how well those posts are still doing. So, no regret. 2010 was a good year. Oh, and I was on This Developer's Life this year! Yay! Anyways, thank you all for reading me. Please continue doing that. And happy 2011!

• How can I recover Google Chrome extensions, settings after a Linux crash?

  - by Norman Ramsey

  I'm running Google Chrome 5.0.307.11 (Official Build 39572) beta on Debian Linux (lenny) kernel version 2.6.26-2-686. The machine is a laptop (Lenovo Thinkpad X300) and sometimes it freezes, usually shortly after wakeup from sleep. The only cure is the power button, but when I restart my Google Chrome web browser after such an event, Settings on the Options menu revert to defaults. Chrome removes all the extensions from ~/.config/google-chrome/Default/Extensions, leaving me with no extensions. The set of "pages last open" is lost. I'd love to know how to poke at the file system in order to recover any or all of this information, especially my extensions. It is a pain to re-do everything by hand each time. How can I recover Google Chrome's extensions and settings after a Linux crash?

• Adding SSE support in Java EE 8

  - by delabassee

  SSE (Server-Sent Event) is a standard mechanism used to push, over HTTP, server notifications to clients.  SSE is often compared to WebSocket as they are both supported in HTML 5 and they both provide the server a way to push information to their clients but they are different too! See here for some of the pros and cons of using one or the other. For REST application, SSE can be quite complementary as it offers an effective solution for a one-way publish-subscribe model, i.e. a REST client can 'subscribe' and get SSE based notifications from a REST endpoint. As a matter of fact, Jersey (JAX-RS Reference Implementation) already support SSE since quite some time (see the Jersey documentation for more details). There might also be some cases where one might want to use SSE directly from the Servlet API. Sending SSE notifications using the Servlet API is relatively straight forward. To give you an idea, check here for 2 SSE examples based on the Servlet 3.1 API.  We are thinking about adding SSE support in Java EE 8 but the question is where as there are several options, in the platform, where SSE could potentially be supported: the Servlet API the WebSocket API JAX-RS or even having a dedicated SSE API, and thus a dedicated JSR too! Santiago Pericas-Geertsen (JAX-RS Co-Spec Lead) conducted an initial investigation around that question. You can find the arguments for the different options and Santiago's findings here. So at this stage JAX-RS seems to be a good choice to support SSE in Java EE. This will obviously be discussed in the respective JCP Expert Groups but what is your opinion on this question?
