• Storing parameters from a graph and applying to other graphs

  - by Braden

  I would like to store the xmin and xmax parameters from one geom_histogram and apply them to a second geom_histogram. I am putting both graphs on the same page using grid.arrange and would like them to have the same x range, while allowing the first graph to establish the range based on its data. The second graph is produced from a subset of the first graphs data, so it will not have data that falls outside of the x-range established by the first. But I don't want the range to shrink to fit the second graph.

• Extend PickerViews Component while touching

  - by vikingosegundo

  I have a UIPickerView with a variable number of components to display. In its contoller i have this -pickerView:withForComponent: - (CGFloat)pickerView:(UIPickerView *)pv widthForComponent:(NSInteger)component { CGFloat f; if (component == 0) { f = 30; } else { if ([componentsData count]>2) { f = 260.0/([componentsData count]-1); } else{ f = 260.0; } } return f; } this works fine if I call [pickerView reloadAllComponents], but how could I extend a components width if it is touched (and of course shrink all others)?

• IE issues with drag/drop (script.aculo.us)

  - by deb

  I have a page with a left and a right div. Inside each of these there are several divs. I can drag&drop them inside the left/right divs or move from one to the other So the page is something like ........ ........ ........ ........ I am using scriptaculous and prototype for the drag&drop If I drag in Firefox things work fine. In IE6-IE8 however I have 2 problems: 1) When I drag from left to right or the other way around, the inner divs do not keep their relative distances: the div I moved now overlaps with the div on the opposite side (if I do a reload of the page the divs are set correctly again) 2) If I shrink the window width below a certain width the divs either on the left or the right droppable disappear. Any ideas? deb

• What CSS attribute stops my site squidging up?

  - by SLC

  I am looking at a website on the internet with the standard centered box design (the entire site is centered in a box and has a border each side). As you shrink it, the border gets smaller but the content stays the same size. This is fine. However on their site, once you get smaller still, you simply get scrollbars. The content remains untouched. On my site if you do this, things like text and links start to scroll onto multiple lines and the whole site gets broken. How can I keep it the same even when the viewport is small?

• UISplitViewController Common View

  - by saikamesh

  is it possible to have a common view for both master and detail view controllers. What if I need to add a header image(at top, the very first view) common for both the master and detail view controllers. When the device is in the portrait mode the width of the header image view has to shrink to fit to the detail view controller's view and when the orientation changes to landscape the width of the same header image view has to be expanded that is the width of it has to be 1024. Please tell me whether doing this is possible. or any workaround for this?

• Div smart width

  - by Mark

  see fiddle html <div class="e" style="left:5px;top:5px;">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa bbbbbbbbbbbbbbbbbbbbbbbbbb</div> <div class="e" style="left:5px;top:100px;">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</div>? css .e { font-size: 10px; font-family: arial; background-color: yellow; position: absolute; max-width: 300px; } you will notice the 2nd div fits the size of the content exactly, but on the first div there's a bunch of empty space to the right of the a's and b's. This is because the div hit its max width of 300px and then wrapped the b's to a 2nd line. The wrapping is good, but then I would expect the div to then shrink back down to the width of the a's so that there's no empty space to the right. Is it possible to get it to do this? Tested in Chrome and FF.

• Java Pack No Resize

  - by ikurtz

  i am learning Java at the moment and have the following question: i am adding my controls to JFrame and then pack() before displaying. this runs the application and all is very nice. i was wondering is there a way to stop the user from resizing the application window? also is there a way to for the image in JLabel to expand as the user changes the application window? at the moment i have it as: constraints.fill = GridBagConstraints.BOTH; constraints.anchor = GridBagConstraints.CENTER; and it only centers the image, i would like to be able to expand/shrink the image. thanks.

• Removing an element from an array (PHP)

  - by morpheous

  I want to remove an element from a PHP array (and shrink the array size). Just looking at the PHP docs, it seems this can be done using array_slice() and array_merge() so I am guessing (off the top of my head) that some combination of array_merge() and array_slice will work. However, array_slice() requires an index (not a key), so I'm not sure how to quickly cobble these functions together for a solution. Has anyone implemented such a function before?. I'm sure it must be only a few lines long, but I cant somehow get my head around it (its been one of those days) ... Actually, I just came up with this cheesy hack when writing up this question.... function remove_from_array(array $in, value) { return array_diff($in, (array)$value); } too ugly? or will it work (without any shocking side effects)?

• HPC Server Dynamic Job Scheduling: when jobs spawn jobs

  - by JoshReuben

  HPC Job Types HPC has 3 types of jobs http://technet.microsoft.com/en-us/library/cc972750(v=ws.10).aspx · Task Flow – vanilla sequence · Parametric Sweep – concurrently run multiple instances of the same program, each with a different work unit input · MPI – message passing between master & slave tasks But when you try go outside the box – job tasks that spawn jobs, blocking the parent task – you run the risk of resource starvation, deadlocks, and recursive, non-converging or exponential blow-up. The solution to this is to write some performance monitoring and job scheduling code. You can do this in 2 ways: manually control scheduling - allocate/ de-allocate resources, change job priorities, pause & resume tasks , restrict long running tasks to specific compute clusters Semi-automatically - set threshold params for scheduling. How – Control Job Scheduling In order to manage the tasks and resources that are associated with a job, you will need to access the ISchedulerJob interface - http://msdn.microsoft.com/en-us/library/microsoft.hpc.scheduler.ischedulerjob_members(v=vs.85).aspx This really allows you to control how a job is run – you can access & tweak the following features: max / min resource values whether job resources can grow / shrink, and whether jobs can be pre-empted, whether the job is exclusive per node the creator process id & the job pool timestamp of job creation & completion job priority, hold time & run time limit Re-queue count Job progress Max/ min Number of cores, nodes, sockets, RAM Dynamic task list – can add / cancel jobs on the fly Job counters When – poll perf counters Tweaking the job scheduler should be done on the basis of resource utilization according to PerfMon counters – HPC exposes 2 Perf objects: Compute Clusters, Compute Nodes http://technet.microsoft.com/en-us/library/cc720058(v=ws.10).aspx You can monitor running jobs according to dynamic thresholds – use your own discretion: Percentage processor time Number of running jobs Number of running tasks Total number of processors Number of processors in use Number of processors idle Number of serial tasks Number of parallel tasks Design Your algorithms correctly Finally , don’t assume you have unlimited compute resources in your cluster – design your algorithms with the following factors in mind: · Branching factor - http://en.wikipedia.org/wiki/Branching_factor - dynamically optimize the number of children per node · cutoffs to prevent explosions - http://en.wikipedia.org/wiki/Limit_of_a_sequence - not all functions converge after n attempts. You also need a threshold of good enough, diminishing returns · heuristic shortcuts - http://en.wikipedia.org/wiki/Heuristic - sometimes an exhaustive search is impractical and short cuts are suitable · Pruning http://en.wikipedia.org/wiki/Pruning_(algorithm) – remove / de-prioritize unnecessary tree branches · avoid local minima / maxima - http://en.wikipedia.org/wiki/Local_minima - sometimes an algorithm cant converge because it gets stuck in a local saddle – try simulated annealing, hill climbing or genetic algorithms to get out of these ruts   watch out for rounding errors – http://en.wikipedia.org/wiki/Round-off_error - multiple iterations can in parallel can quickly amplify & blow up your algo ! Use an epsilon, avoid floating point errors,  truncations, approximations Happy Coding !

• SQL SERVER – Transaction Log Full – Transaction Log Larger than Data File – Notes from Fields #001

  - by Pinal Dave

  I am very excited to announce a new series on this blog – Notes from Fields. I have been blogging for almost 7 years on this blog and it has been a wonderful experience. Though, I have extensive experience with SQL and Databases, it is always a good idea that we consult experts for their advice and opinion. Following the same thought process, I have started this new series of Notes from Fields. In this series we will have notes from various experts in the database world. My friends at Linchpin People have graciously decided to support me in my new initiation.  Linchpin People are database coaches and wellness experts for a data driven world. In this very first episode of the Notes from Fields series database expert Tim Radney (partner at Linchpin People) explains a very common issue DBA and Developer faces in their career, when database logs fills up your hard-drive or your database log is larger than your data file. Read the experience of Tim in his own words. As a consultant, I encounter a number of common issues with clients.  One of the more common things I encounter is finding a user database in the FULL recovery model that does not make a regular transaction log backups or ever had a transaction log backup. When I find this, usually the transaction log is several times larger than the data file. Finding this issue is very significant to me in that it allows to me to discuss service level agreements with the client. I get to ask questions such as, are nightly full backups sufficient or do they need point in time recovery.  This conversation has now signed with the customer and gets them to thinking about their disaster recovery and high availability solutions. This issue is also very prominent on SQL Server forums and usually has the title of “Help, my transaction log has filled up my disk” or “Help, my transaction log is many times the size of my database”. In cases where the client only needs the previous full nights backup, I am able to change the recovery model to SIMPLE and shrink the transaction log using DBCC SHRINKFILE (2,1) or by specifying the transaction log file name by using DBCC SHRINKFILE (file_name, target_size). When the client needs point in time recovery then in most cases I will still end up switching the client to the SIMPLE recovery model to truncate the transaction log followed by a full backup. I will then schedule a SQL Agent job to make the regular transaction log backups with an interval determined by the client to meet their service level agreements. It should also be noted that typically when I find an overgrown transaction log the virtual log file count is also out of control. I clean up will always take that into account as well.  That is a subject for a future blog post. If your SQL Server is facing any issue we can Fix Your SQL Server.

• SQL SERVER – Iridium I/O – SQL Server Deduplication that Shrinks Databases and Improves Performance

  - by Pinal Dave

  Database performance is a common problem for SQL Server DBA’s.  It seems like we spend more time on performance than just about anything else.  In many cases, we use scripts or tools that point out performance bottlenecks but we don’t have any way to fix them.  For example, what do you do when you need to speed up a query that is already tuned as well as possible?  Or what do you do when you aren’t allowed to make changes for a database supporting a purchased application? Iridium I/O for SQL Server was originally built at Confio software (makers of Ignite) because DBA’s kept asking for a way to actually fix performance instead of just pointing out performance problems. The technology is certified by Microsoft and was so promising that it was spun out into a separate company that is now run by the Confio Founder/CEO and technology management team. Iridium uses deduplication technology to both shrink the databases as well as boost IO performance.  It is intriguing to see it work.  It will deduplicate a live database as it is running transactions.  You can watch the database get smaller while user queries are running. Iridium is a simple tool to use. After installing the software, you click an “Analyze” button which will spend a minute or two on each database and estimate both your storage and performance savings.  Next, you click an “Activate” button to turn on Iridium I/O for your selected databases.  You don’t need to reboot the operating system or restart the database during any part of the process. As part of my test, I also wanted to see if there would be an impact on my databases when Iridium was removed.  The ‘revert’ process (bringing the files back to their SQL Server native format) was executed by a simple click of a button, and completed while the databases were available for normal processing. I was impressed and enjoyed playing with the software and encourage all of you to try it out.  Here is the link to the website to download Iridium for free. .

• WPF Control Toolkits Comparison for LOB Apps

  In preparation for a new WPF project Ive been researching options for WPF Control toolkits.  While we want a lot of the benefits of WPF, the application is a fairly typical line of business application (LOB).  So were not focused on things like media and animations, but instead a simple, solid, intuitive, and modern user interface that allows for well architected separation of business logic and presentation layers. While WPF is mature, it hasnt lived the long life that Winforms has yet, so there is still a lot of room for third party and community control toolkits to fill the gaps between the controls that ship with the Framework.  There are two such gaps I was concerned about.  As this is an LOB app, we have needs for presenting lots of data and not surprisingly much of it is in grid format with the need for high performance, grouping, inline editing, aggregation, printing and exporting and things that weve been doing with LOB apps for a long time.  In addition we want a dashboard style for the UI in which the user can rearrange and shrink and grow tiles that house the content and functionality.  From a cost perspective, building these types of well performing controls from scratch doesnt make sense.  So I evaluated what you get from the .NET Framework along with a few different options for control toolkits.  I tried to be fairly thorough, but know that this isnt a detailed benchmarking comparison or intense evaluation.  Its just meant to be a feature set comparison to be used when thinking about building an LOB app in WPF.  I tried to list important feature differences and notes based on my experience with the trial versions and what I found in documentation and reference materials and samples.  Ive also listed the importance of the controls based on how I think they are needed in LOB apps.  There are several toolkits available, but given I dont have unlimited time, I picked just a few.  Maybe Ill add on more later.  The toolkits I compared are: Teleriks RadControls for WPF since I had heard some good things about Telerik Infragistics NetAdvantage WPF since both I and the customer have some experience with the vendors tools WPF Toolkit on codeplex since many of my colleagues have used it Blacklight codeplex project which had WPF support for the Tile View control  (with Release 4.3 WPF is not going to be supported in favor of focusing only on SilverLight controls, so I dropped that from the comparison) Click Here to Download the WPF Control Toolkits Comparison Hopefully this helps someone out there.  Feel free to post a comment on your experiences or if you think something I listed is incorrect or missing.  Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Walmart's Mobile Self-Checkout

  - by David Dorf

  Reuters recently reported that Walmart was testing an iPhone-based self-checkout at a store near its headquarters.  Consumers scan items as they're placed in the physical basket, then the virtual basket is transferred to an existing self-checkout station where payment is tendered.  A very solid solution, but not exactly original. Before we go further, let's look at the possible cost savings for Walmart.  According to the article: Pushing more shoppers to scan their own items and make payments without the help of a cashier could save Wal-Mart millions of dollars, Chief Financial Officer Charles Holley said on March 7. The company spends about $12 million in cashier wages every second at its Walmart U.S. stores. Um, yeah. Using back-of-the-napkin math, I calculated Walmart's cashiers are making $157k per hour.  A more accurate statement would be saving $12M per year for each second saved on the average transaction time.  So if this self-checkout approach saves 2 seconds per transaction on average, Walmart would save $24M per year on labor.  Maybe.  Sometimes that savings will be used to do other tasks in the store, so it may not directly translate to less employees. When I saw this approach demonstrated in Sweden, there were a few differences, which may or may not be in Walmart's plans.  First, the consumers were identified based on their loyalty card.  In order to offset the inevitable shrink, retailers need to save on labor but also increase basket size, typically via in-aisle promotions.  As they scan items, retailers should target promos, and that's easier to do if you know some shopping history.  Last I checked, Walmart had no loyalty program. Second, at the self-checkout station consumers were randomly selected for an audit in which they must re-scan all the items just like you do at a typical self-checkout.  If you were found to be stealing, your ability to use the system can be revoked.  That's a tough one in the US, especially when the system goes wrong, either by mistake or by lying.  At least in my view, the Swedes are bit more trustworthy than the people of Walmart. So while I think the idea of mobile self-checkout has merit, perhaps its not right for Walmart.

• Correct way to handle path-finding collision matrix

  - by Xander Lamkins

  Here is an example of me utilizing path finding. The red grid represents the grid utilized by my A* library to locate a distance. This picture is only an example, currently it is all calculated on the 1x1 pixel level (pretty darn laggy). I want to make it so that the farther I click, the less accurate it will be (split the map into larger grid pieces). Edit: as mentioned by Eric, this is not a required game mechanic. I am perfectly fine with any method that allows me to make this accurate while still fast. This isn't the really the topic of this question though. The problem I have is, my current library uses a two dimensional grid of integers. The higher the number in a cell, the more resistance for that grid tile. Currently I'm setting all unwalkable spots to Integer Max. Here is an example of what I want: I'm just not sure how I should set up the arrays of integers of the grid. Every time an element is added/removed to/from the game, it's collision details are updated in the table. Here is a picture of what the map looks like on my collision layer: I probably shouldn't be creating new arrays every time I have to do a path find because my game needs to support tons of PF at the same time. Should I have multiple arrays that are all updated when the dynamic elements are updated (a building is built/a building is destroyed). The problem I see with this is that it will probably make the creation and destruction of buildings a little more laggy than I would want because it would be setting the collision grid for each built in accuracy level. I would also have to add more/remove some arrays if I ever in the future changed the map size. Should I generate the new array based on an accuracy value every time I need to PF? The problem I see with this is that it will probably make any form of PF just as laggy because it will have to search through a MapWidth x MapHeight number of cells to shrink it all down. Or is there a better way? I'm certainly not the best at optimizing really anything. I've just started dealing with XNA so I'm not used to having optimization code really doing much of an affect until now... :( If you need code examples, please ask. I'll add it as an edit. EDIT: While this doesn't directly relate to the question, I figure the more information I provide, the better. To keep your units from moving as accurately to the players desired position, I've decided that once the unit PFs over to the less accurate grid piece, it will then PF on a more accurate level to the exact position requested.

• Why is my dual-boot Ubuntu partition showing up as a peripheral "root.disk"?

  - by Don

  I recently installed Ubuntu 12.04, which I had been booting from a usb key, as a dual-boot on my machine running Windows 7. From what I had read online while researching, I was prepared to have to shrink the Windows partition and all that. But I never had to - it really was just a few clicks here and there and it was installed. I'm still pretty confused about it, but whatever, it worked, and the two peacefully coexist on my machine, and I have broken things to fix before I worry about fixing unbroken things. So yesterday I got it in my head to look at my partitions (I was considering making an all new partition to install the Windows 8 Release Preview). What I saw confused me. Here's a screenshot of the disk utility. At this moment, there is nothing connected to my computer, and nothing in any of the optical drives/ports/card readers/etc. Can you help me figure out what's going on here? Don's Machine is, I believe, my Windows partition - that's the name I assigned my machine from Windows Explorer. PQSERVICE is from what I can find online also Windows, but having to do with backup. And SYSTEM REQUIRED, if I browse it in Ubuntu, is definitely something to do with booting, and I believe it is also Windows'. According to the sizes shown, those three together should use up my 500 GB HD. Then further down, as a "peripheral device", it lists that 31 GB disk. This is obviously my Ubuntu (Model:Linux Loop:root.disk), but why is it showing up as a peripheral? So, to sum up those questions and to add some more random ones I had: Why is Ubuntu showing up as a peripheral device? If the Windows sections take up all 500 GB, where does Ubuntu live? If I renamed the disk partitions, would my life become a nightmare (seriously - can I safely rename them)? Why didn't I have to resize the Windows partition in the first place? Would giving Ubuntu more space improve its performance (it hangs alot)? Is it possible to have a partition for each OS (Windows 7 & 8, Ubuntu), a partition for files, and a separate partition for backups? Is this towards the good or bad idea end of the spectrum? @Elfy, would that explain why it keeps hanging? I guess I'll backup my files, rip it out, and reinstall it correctly later on today.

• Pixels - A cry for some insight

  - by CarrotFile

  I'm pretty new to web developing and I'd love some clarification. Although reading more than one book on the topic, I cannot seem to wrap my head around the pixel concept. I encounter problems with this issue when trying to use CSS and pixel units for design that fits different screen sizes. To my understanding a pixel is the most basic unit used by a monitor in order to compose an image on the screen. So if me resolution is 800 by 600, everything on my screen is rendered using those 800*600 basic building blocks. If I were to enlarge my screen resolution, 3 things would accrue: A. The basic image building block(the pixel) would shrink in size B. The pixels would move close together C. Well, more pixels would now be available All these combined lead to a sharper(depending on the viewing distance) and more detail enabling image. Well so far so good. Here is were I start getting lost: To my knowledge a pixel is not a physical, real object. Monitors are not embedded with a few thousand pixels. I am drawn to this conclusion because anyone can change his screen's resolution, making a pixel on his screen bigger or smaller, and adding or subtracting the amount of total pixels on screen. Adding to that, I have herd that different monitors have different pixel densities. For example Apple's retina monitors. Taking all of the above as my knowledge base, These are my questions: If a pixel has no real world constant size, what does comparing different pixel densities matter? Each screen company can define it's own pixel concept and declare the higher density. What does a bigger pixel density mean? Say we take two screens with the same physical dimensions, but with a different pixel density, am I to assert that the main difference would be the larger density screen being able to display a higher max resolution? Or am I to assert that given the same resolution on both monitors, the higher density one would display a sharper, smaller image? If a pixel is not a fixed size within one monitor, is it a fixed size between the same resolution on two different monitors? For example, would two different monitors, set to the same resolution, be comprised of same size, same quantity pixels? I'd love some help (:

• Weird Ubuntu Desktop Boot Partition On External Hard Drive

  - by Magnitus

  I have a Thinkpad with Windows 7. Last time I installed an Ubuntu/Windows dual boot, Windows was never same after and regularly got corrupted so this time, I installed Ubuntu on a separate external hard drive. I took a 500 GB external hard drive and used Windows to shrink the partition on it to 400 GB, freeing 100 GB to install Ubuntu. Then I modified the booting priority of my computer to boot from the external hard drive if present. Then, I installed Ubuntu desktop on the external hard drive using a DVD, picked the most simplistic partitioning scheme I could get away with (didn't go auto as it didn't include the external hard drive as a choice) and voilà. Fast forward some time and I'm trying to refresh my understanding of Linux partitions to install a bunch of servers, so I'm looking at the current partitioning scheme on my external hard drive and find the boot partition puzzling... sda is my integrated hard drive with Windows 7. sdb is my Ubuntu desktop external hard drive. Running parted on sdb, I get this: (parted) print Model: WD My Passport 0740 (scsi) Disk /dev/sdb: 500GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 393GB 393GB primary ntfs boot 2 393GB 500GB 107GB extended 5 393GB 425GB 32.8GB logical linux-swap(v1) 6 425GB 500GB 74.6GB logical ext4 At this point, I'm wondering why the ntfs partition is flagged as "boot" and not my ext4 partition which is the partition that contains / (and by extension, /boot since it's not on its own separate partition). Looking at mtab only confirms what I already know: eric@eric-ThinkPad-W530:~$ sudo cat /etc/mtab /dev/sdb6 / ext4 rw,errors=remount-ro 0 0 proc /proc proc rw,noexec,nosuid,nodev 0 0 sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0 none /sys/fs/cgroup tmpfs rw 0 0 none /sys/fs/fuse/connections fusectl rw 0 0 none /sys/kernel/debug debugfs rw 0 0 none /sys/kernel/security securityfs rw 0 0 udev /dev devtmpfs rw,mode=0755 0 0 devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=0620 0 0 tmpfs /run tmpfs rw,noexec,nosuid,size=10%,mode=0755 0 0 none /run/lock tmpfs rw,noexec,nosuid,nodev,size=5242880 0 0 none /run/shm tmpfs rw,nosuid,nodev 0 0 none /run/user tmpfs rw,noexec,nosuid,nodev,size=104857600,mode=0755 0 0 none /sys/fs/pstore pstore rw 0 0 systemd /sys/fs/cgroup/systemd cgroup rw,noexec,nosuid,nodev,none,name=systemd 0 0 gvfsd-fuse /run/user/1000/gvfs fuse.gvfsd-fuse rw,nosuid,nodev,user=eric 0 0 /dev/sdb1 /media/eric/My\040Passport fuseblk rw,nosuid,nodev,allow_other,default_permissions,blksize=4096 0 0 My lack of understanding concerning this is not vital to anything (this is only my development desktop partition), but somehow annoys me. Any insight that could shed some light on this would be welcome.

• Viewing a large-resolution VNC server through a small-resolution viewer in Ubuntu

  - by Madiyaan Damha

  I have two Ubuntu computers, one with a large screen resolution (1920x1600) that is running default ubuntu vnc server. I have another computer that has a resolution of about 1200x1024 that I use to vnc into the server (I use the default ubuntu vnc viewer). Now everything works fine except there are annoying scrollbars in the viewer because the server's desktop resolution is so much higher than the viewer's. Is there a way to: 1) Scale the server's desktop down to the viewer's resolution. I know there will be a loss of image quality, but I am willing to try it out. This should be something like how windows media player or vlc scales down the window (and does some interpolation of pixels). 2) Automatically shrink the resolution of the server to the client's when I connect and scale the resolution back when I disconnect. This seems like a less attractive solution. 3) Any other solution that gurus out there use? I am sure someone has experienced this before (annoying scroll bars) so there must be a solution out there. Thanks,

• What is the best / latest software to convert DVD recorder disc to YouTube?

  - by Jian Lin

  I recorded some Wii gameplay to a DVD-R using a DVD recorder, and tried using Handbrake to convert it to YouTube compatible format. Basically, it needs resizing to 16:9, and selecting 00:03 to 3:10 of the chapter (out of the 7 minutes). It seems Handbrake can't do it for 480p... and if using AutoGK and then VirtualDub to resize and do video time selection, it feels so old school (autogk not updated since 2005)... Windows Movie Maker seems like 15fps video quality... Is there a way to do it nicely? Details if using Handbrake: I can't find a way to convert a DVD recorded video which is 720 x 480 (Wii Gameplay in 16 : 9 ratio) into 852 x 480... It seems that the only possible resize is to shrink but not to expand? It is fine to make it 720 x 406... except YouTube won't be able to show it as 480p... If it can be made 852 x 480, then YouTube can at least show it as 480p (besides 360p and 240p)... is there any way to do it? thanks.

• DRBD on a disk with existing file system that takes all the place

  - by Karolis T.

  I'm currently trying to simulate the environment via XEN. I have installed two debian systems with such FS layout: cltest1:/etc# df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda2 6.0G 417M 5.2G 8% / tmpfs 257M 0 257M 0% /lib/init/rw udev 10M 16K 10M 1% /dev tmpfs 257M 4.0K 257M 1% /dev/shm Host cltest2 is identical. Here's my drbd.conf global { minor-count 1; } resource mysql { protocol C; syncer { rate 10M; # 10 Megabytes } on cltest1 { device /dev/drbd0; disk /dev/xvda2; address 192.168.1.186:7789; meta-disk internal; } on cltest2 { device /dev/drbd0; disk /dev/xvda2; address 192.168.1.187:7789; meta-disk internal; } } I have not created filesystem on drbd0 Starting DRBD via init.d script errors out with: Starting DRBD resources: [ d(mysql) /dev/drbd0: Failure: (114) Lower device is already claimed. This usually means it is mounted. [mysql] cmd /sbin/drbdsetup /dev/drbd0 disk /dev/xvda2 /dev/xvda2 internal --set-defaults --create-device failed - continuing!

You need to either * use external meta data (recommended) * shrink that filesystem first * zero out the device (destroy the filesystem) Operation refused. Command 'drbdmeta /dev/drbd0 v08 /dev/xvda2 internal create-md' terminated with exit code 40 drbdadm aborting As I understand, all of my problems are because I don't have unallocated disk space on xvda2. What are my options besides shrinking FS and connecting a separate physical disk? Can't the meta-data be stored on a file in the local filesystem?

• Convert DVD Movie to MPEG and view on PS3 via Windows Media Server 12

  - by Vidar

  I think Apollo spacecraft missions to the moon were easier than this! I have tried dozens of DVD ripping software and media servers and have had limited success in trying to convert all my DVDs into file format so they can be viewed on PS3. I have also been on dozens of forums and it's all getting a bit confusing, some advice is out of date, some software is no longer updated - updates have been applied to PS3 operating system and windows and so on and so on. There has to be a way to get all this knowledge and information in one place that's up to date so people can do the same thing as me. Can anyone give me some definitive software and/or advice to do the following: I have over 200 DVDs - I want to convert these to VOB files (rename to MPEG so WMS can stream them). Store on hard disk and view via Windows Media Server 12 (Windows 7). I will then be able to view these via my PS3 in my lounge and never have to get out another DVD case again. I don't want to encode to any other format like MP4 with H.264 because I will lose some of the original quality. So MPEG-2 is fine for me. Note: I have been using DVD Shrink but it gives odd results sometimes. The main problem being that once the DVD has been ripped - WMS shows the wrong playing length of the film, however if I use VLC Media Player it will play through the whole film OK. This is obviously no good when it comes to streaming on the PS3.

• Viewing a large-resolution VNC server through a small-resolution viewer in Ubuntu

  - by Madiyaan Damha

  I have two Ubuntu computers, one with a large screen resolution (1920x1600) that is running the default Ubuntu VNC server. I have another computer that has a resolution of about 1200x1024 that I use to VNC into the server using the default Ubuntu VNC viewer). Now everything works fine except there are annoying scrollbars in the viewer because the server's desktop resolution is so much higher than the viewer's. Is there a way to: Scale the server's desktop down to the viewer's resolution. I know there will be a loss of image quality, but I am willing to try it out. This should be something like how Windows Media Player or VLC scales down the window (and does some interpolation of pixels). Automatically shrink the resolution of the server to the client's when I connect and scale the resolution back when I disconnect. This seems like a less attractive solution. Any other solution that gurus out there use? I am sure someone has experienced this before (annoying scroll bars) so there must be a solution out there.

• Thundrbird 3: can't change column width?

  - by rumtscho

  I recently installed Thunderbird 3.0.3. Just noticed a suboptimal UI setting: in the upper pane, which lists the e-mails in the current folder, the Date column is about 200px wide. So when I keep the window at 480x600, all I see in a row is: | tree icon | favourites icon | attachment icon | read icon | junk icon | Date and time, followed by 5cm whitespace | ... | P Where "P" is the first letter of the name of the sender. And the "..." is actually shown this way, I have no idea which column it is meant to be. But I don't see neither the sender, nor the message subject, which makes scrolling a folder for a certain mail rather pointless. I see these when I maximize the window, actually the columns are then not only bigger, they are arranged in another sequence. But I feel that holding a mail client permanently maximised at 1600x1200 is a waste of screen real estate. My naive solution attempt was to try to go with the mouse cursor to the right edge of the date column and try to shrink it by moving the cursor left while holding down the left mouse button. Not only is this default behaviour for all resizable columns I've ever encountered in GUIs, the cursor actually turns into a horizontal double-headed arrow. But pulling has no effect at all. I cannot make a wide column narrow, and I cannot make the narrow columns wide. I didn't find anything in the preferences either. So can please somebody explain how to get the columns arranged sensibly?

• Fix Video timelines

  - by Josh

  So, I have been going through and riping all of my DVD's and it seems that the way to get the highest quality out of these is to have DVD Shrink de-encrypt, rip, and decompress, the DVD's. After that I usually end up with a high quality (high size) set of .vob files in a classic DVD structure. Then I use a python script that I wrote to automate the process of finding the title sequence and then combining all of the title sequences' .vob files together into one file(similar to the "copy /b" command in windows), and then changing the extension to .mpg (a more widely supported format then .vob). This allows me to get a high quality rip in about 40 min. The problem comes in playing the files. I need all of the ripped dvd's to play on my media computer using windows media center but windows media center (and vlc for that matter) all think that the video files are anywhere from 5 min. to 0 min. which is not a problem (the video will still play all the way through) but if you want to pause it, when it is unpaused the video will start all the way over (Also fast forward and rewind don't work). I suspect that it is something wrong with the way the timeline is encoded in the video file, various forums on the internet recommended using virtualdub to fix the errors. But when I try to open the file virtual dub says that the file is not in mpeg-1 encoding and may be in mpeg-2. Is there any way to fix this? PS: I am aware that there was a similar question but it hasn't had any activity for 2 months and is dealing more with wmv files.
