• New Release of Oracle Berkeley DB

  - by Eric Jensen

  We are pleased to announce that a new release of Oracle Berkeley DB, version 11.2.5.2.28, is available today. Our latest release includes yet more value added features for SQLite users, as well as several performance enhancements and new customer-requested features to the key-value pair API.  We continue to provide technology leadership, features and performance for SQLite applications.  This release introduces additional features that are not available in native SQLite, and adds functionality allowing customers to create richer, more scalable, more concurrent applications using the Berkeley DB SQL API. This release is compelling to Oracle’s customers and partners because it: delivers a complete, embeddable SQL92 database as a library under 1MB size drop-in API compatible with SQLite version 3 no-oversight, zero-touch database administration industrial quality, battle tested Berkeley DB B-TREE for concurrent transactional data storage New Features Include: MVCC support for even higher concurrency direct SQL support for HA/replication transactionally protected Sequence number generation functions lower memory requirements, shared memory regions and faster/smaller memory on startup easier B-TREE page size configuration with new ''db_tuner" utility New Key-Value API Features Include: HEAP access method for constrained disk-space applications (key-value API) faster QUEUE access method operations for highly concurrent applications -- up 2-3X faster! (key-value API) new X/open compliant XA resource manager, easily integrated with Oracle Tuxedo (key-value API) additional HA/replication management and communication options (key-value API) and a lot more!

• Oscillating Sprite Movement in XNA

  - by Nick Van Hoogenstyn

  I'm working on a 2d game and am looking to make a sprite move horizontally across the screen in XNA while oscillating vertically (basically I want the movement to look like a sin wave). Currently for movement I'm using two vectors, one for speed and one for direction. My update function for sprites just contains this: Position += direction * speed * (float)t.ElapsedGameTime.TotalSeconds; How could I utilize this setup to create the desired movement? I'm assuming I'd call Math.Sin or Math.Cos, but I'm unsure of where to start to make this sort of thing happened. My attempt looked like this: public override void Update(GameTime t) { double msElapsed = t.TotalGameTime.Milliseconds; mDirection.Y = (float)Math.Sin(msElapsed); if (mDirection.Y >= 0) mSpeed.Y = moveSpeed; else mSpeed.Y = -moveSpeed; base.Update(t, mSpeed, mDirection); } moveSpeed is just some constant positive integer. With this, the sprite simply just continuously moves downward until it's off screen. Can anyone give me some info on what I'm doing wrong here? I've never tried something like this so if I'm doing things completely wrong, let me know!

• Is using something other than XML advisable for my configuration file?

  - by Earlz

  I have a small tool I'm designing which would require a configuration file of some sort. The configuration file in my case is really more of a database, but it needs to be lightweight, and if needed the end-user should find it easily editable. However, it also will contain a lot of things in it. (depending on certain factors, could be 1Mb or more) I've decided I'd rather use plain ol' text, rather than trying to use SQLite or some such. However, with using text, I also have to deal with the variety of formats. So far, my options are XML JSON Custom format The data in my file is quite simple consisting for the most part of key-value type things. So, a custom format wouldn't be that difficult... but I'd rather not have to worry about writing the support for it. I've never seen JSON used for configuration files. And XML would bloat the file size substantially I think. (I also just has a dislike of XML in general). What should I do in this case? Factors to consider: This configuration file can be uploaded to a web service(so size matters) Users must be able to edit it by hand if necessary(ease of editing and reading matters) Must be able to generate and process automatically (speed doesn't matter a lot, but not excessively slow) The "keys" and "values" are plain strings, but must be escaped because they can contain anything. (unicode and escaping has to work easily)

• How to start gnome-shell?

  - by Tim

  I successfully installed the gnome 3 gnome-shell from the launchpad ppa on my fully updated Natty test system. However, nothing I tried could get it to actually run. If I selected it in the startup options, I got a plain light blue screen with absolutely nothing on it. If I tried to start it using "gnome-shell --replace", I got: gnome-shell --replace & [2] 3251 tim@nattytest:/usr/lib$ Traceback (most recent call last): File "/usr/bin/gnome-shell", line 705, in normal_exit = run_shell() File "/usr/bin/gnome-shell", line 293, in run_shell if shell is None: UnboundLocalError: local variable 'shell' referenced before assignment /usr/bin/compiz (core) - Error: Screen 0 on display ":0.0" already has a window manager; try using the --replace option to replace the current window manager. [2]+ Exit 1 gnome-shell --replace I also tried preceding that with metacity --replace, as suggested at ubuntuforums.com. But, I got the same failure. I also linked /usr/lib/libmozjs.so to /usr/lib/xulrunner-2.0b12/libmozjs.so, which did not help either. No matter what I try, I get the same error messages. Thanks.

• Scaling Scrum within a group of 100s of programmers

  - by blunders

  Most Scrum teams lean toward 7-15 people **, though it's not clear how to scale Scrum among 100s of people, or how the effectiveness of a given team might be compared to another team within the group; meaning beyond just breaking the group into Scrum teams of 7-15 people, it's unclear how efforts between the teams are managed, compared, etc. Any suggestions related to either of these topics, or additional related topics that might be of more importance to account for in planning a large scale SCRUM grouping? ** In reviewing research related to the suggested size of software development teams, which appears to be the basis for the suggested Scrum team size, I found what appears to be an error in the research which oddly appears to show that bigger teams (15+ ppl), not smaller teams (7 ppl) are better. UPDATE, "Re: Scrum doesn't scale": Made huge amounts of progress on personally researching the topic, but thought I'd respond to the general belief of some that Scrum doesn't scale by citing a quote from Succeeding with Agile by Mike Cohn : Scrum Does Scale: You have to admire the intellectual honesty of the earliest agile authors. They were all very careful to say that agile methodolgies like Scrum were for small projects. This conservatism wasn’t because agile or Scrum turned out to be unsuited for large projects but because they hadn’t used these processes on large projects and so were reluctant to advise their readers to do so. But, in the years since the Agile Manifesto and the books that came shortly before and after it, we have learned that the principles and practices of agile development can be scaled up and applied on large projects, albeit it with a considerable amount of overhead. Fortunately, if large organizations use the techniques described regarding the role of the product owner, working with a shared product backlog, being mindful of dependencies, coordinating work among teams, and cultivating communities of practice, they can successfully scale a Scrum project.

• Affect movieclip scale from a .as doc to another

  - by Madcowe

  I've been working on a game following a tutorial on the internet, the game is an avoider where you have the Avatar, that has to avoid the objects that fall. The way it is made is: I have a DocumentClass which addChild's the screen you should be seeing and removeChild's the screen that you were. For example: first it loads the menuScreen, then when you press play unloads menu and loads playscreen. When you die it loads the gameoverScreen and loads the playscreen. And from the gameOverScreen you can press the SHOP button to go to the shop. From here on I'm on my own and not following any tutorials. The shop has a button that is supposed to alter the Avatar's X and Y scale to 0.5, but the problem is: how do I make that work? I tried creating a sharedObject.data.avatarSize, on the store's size button the code would be something like: sharedObject.data.avatarSize *= 0.5; And on the AvoiderGame.as, which is the most of the actual game, on the part where the avatar is created I tried putting this after it's creation: scaleX.avatar = sharedObject.data.avatarSize; scaleY.avatar = sharedObject.data.avatarSize; This did not work since it gives me the error 1009 saying can't access something that is null. I tried this before "using" the sharedObject: if( sharedObject.data.avatarSize == null ) { sharedObject.data.avatarSize = 1; } But it did not work... So now I'm not sure on what to do. I know we should reduce global variables as much as we can but how do I do it? Also, if it helps, I'm using Flash CS5 and working with AS3.0

• Error mounting: mount exited with exit code 13

  - by Mike Williamson

  I keep a windows partition on my laptop for the occaisional bit of Photoshop work. A while ago I noticed that Windows had disappeared from my grub boot menu and when I try to mount the windows partion, my system hangs for a bit and then I get this: Unable to mount 105 GB Filesystem Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to calculate free MFT records: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. It seems that chkdsk is a windows command but since I can't boot into windows (since its the windows partition that is the problem) I'm not sure what to do. Here is the output of fdisk to give you the lay of the land: Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x98000000 Device Boot Start End Blocks Id System /dev/sda1 1 10199 81923436 83 Linux /dev/sda2 * 10200 22947 102398310 7 HPFS/NTFS /dev/sda3 22948 29164 49938052+ 83 Linux /dev/sda4 29165 30401 9936202+ 5 Extended /dev/sda5 29165 30401 9936171 82 Linux swap / Solaris Any guidance would be appreciated!

• Huge email sizes when using mail merge in Word 2010

  - by Nic

  So I've designed an HTML template to send out some emails on. The code is fine, everything looks great there, and it tests just fantastically. I was sending out putting my recipients in the BCC field, but I decided to make it a little more personal and open the file in Word and do an email merge. The HTML file itself is 3.06kb and contains an img src to an absolute URL, which is about 125kb (a little large, I know, but it's very important). When I merge the file from Word 2010 - Outlook 2010, the email size jumps to about 250kb. It's not much, I know, but I'm a gigantic nerd and I'm stuck thinking it should be about 5kb with MIME overhead. Here's the file list on one of the test emails: File Size image001.png 104366 image002.gif 43 MESSAGE 1259 Mime.822 152575 TEXT.htm 5712 Since the img src is specified, I'm not sure why these are coming through. If this is an issue inherent to Outlook, I'd be happy to explore other options.

• mdadm auto grow raid

  - by johannes

  I have a raid0/1 on lvm logical volumes. I resized the logical volumes. Now I want to resize the raid to use the complete logical volumes. This can be done with mdadm /dev/md? --grow -z newsize But somehow I can't figure out how to calculate the newsize argument. Is there a way to tell mdadm to grow to the biggest possible size? If not, how do I calculate the biggest possible size of the raid to use for the newsize argument?

• My sound stopped working today, how can I fix it?

  - by Oli

  This seems to be a problem with pulseaudio. I was logged in over VNC on my phone and started playing a video this caused X to crash (as sometimes happens). I restarted and suddenly the sound doesn't work. I have a Intel HDA/Realtek ALC889 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller alsamixer is detecting this just fine. PulseAudio doesn't detect this alsa device so is using auto_null as the default sink (logs below). When I properly kill PulseAudio (tell it not to auto-start) direct ALSA communication with the sound card works just fine. speaker-test, for example, works. So the hardware and ALSA layers are fine IMO. In the logs, it seems that the card might be "busy" but I really don't know how or why it would be now (and never before). Is there an ALSA lock file somewhere that it still there because of my crash? I just ran sudo fuser /dev/snd/* and saw this: oli@bert:~$ sudo fuser /dev/snd/* /dev/snd/controlC0: 1884 /dev/snd/pcmC0D0c: 1884m /dev/snd/timer: 1884 A look at the process list (ps aux | grep 1884) tells me process 1884 is arecord -c 1 -f S16_LE -r 8000 -t raw. No idea what this is or why it's running. When I try and kill arecord (as root), it just respawns and rebinds on the hardware. I'm in a very annoying situation where I don't know what is going on and don't know how to find out. I'm open to all suggestions to get this working again. Fire away. And here's what I get when I stop PA auto-loading, kill it and then start it with -vvvv. oli@bert:~$ pulseaudio -vvvvv I: main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted I: main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted D: core-rtclock.c: Timer slack is set to 50 us.

• Apparent leak in Mozilla Firefox

  - by LeopardSkinPillBoxHat

  I use Mozilla Firefox 3.6 all day, opening and closing tabs quite regularly. I am noticing over time that the firefox.exe process size keeps growing and growing over time. Initially I put this down to memory fragmentation caused by opening and closing tabs, but now I am suspecting that there is a memory leak in one of the add-ons that I have installed. The problem I am seeing is that when the process size gets to about 1.5GB in the "Mem Usage" stat in Task Manager (and it gets there quite regularly), Firefox freezes up. Does anyone have any ideas about how I could diagnose whether: Any of the add-ons are leaking memory? Something else is causing this problem?

• How Do I Print Photos?

  - by Takkat

  Other than for Windows in Ubuntu there are no fancy utilities provided from printer manufacturers to print photos. I am aware of Gnome Photo Printer and of Photoprint, the first being easy to handle, the latter having more options. However I wonder if there are any other or maybe even better alternatives (including plugins) to perform the following tasks: Print photos in the best photo-resolution the driver offers Adjust paper size for standard values of photo papers Choose paper tray if the printer has more than one Print out multiple photos on one page including mixed sizes (grids) Multiple prints with same settings Borderless printing if the printer is capable of this Any additional options like pre-processing for color correction or noise reduction would be nice to have but are not so essential. Update According to this spec it seems not to so easy to accomplish the simple task of printing photos. Indeed all applications I have gone through have major drawbacks that make printing photos almost impossible. Below I will list what put me off using them for photo printing: Gnome Photo Printer: no thumbnails, no grids Photoprint: does not keep settings, GUI broken, no standard photo size, no thumbs Eye Of Gnome: no multiple pages, no grids Gimp + Images Grid Layout: far too many steps to finally find that prints are always different to their previews. F-Spot: no grids Picasa 3: no grids, very few fixed paper sizes, 300 dpi only flPhoto: strange GUI, no thumbs, no printer settings, did not print at all Windows: Ooops - everything works fine! But I want Ubuntu to do this! After half a pack of ink cartridges and half a pack of photo paper cards I am getting tired of testing. At least Gimp and Picasa looked promising but both don't keep their promise when it comes to printing. I'd already be happy to quickly print a few photos with EOG if bug #80220 was fixed - but it's still on "wishlist".

• How to create a "retro" pixel shader for transformed 2D sprites that maintains pixel fidelity?

  - by David Gouveia

  The image below shows two sprites rendered with point sampling on top of a background: The left skull has no rotation/scaling applied to it, so every pixel matches perfectly with the background. The right skull is rotated/scaled, and this results in larger pixels that are no longer axis aligned. How could I develop a pixel shader that would render the transformed sprite on the right with axis aligned pixels of the same size as the rest of the scene? This might be related to how sprite scaling was implemented in old games such as Monkey Island, because that's the effect I'm trying to achieve, but with rotation added. Edit As per kaoD's suggestions, I tried to address the problem as a post-process. The easiest approach was to render to a separate render target first (downsampled to match the desired pixel size) and then upscale it when rendering a second time. It did address my requirements above. First I tried doing it Linear -> Point and the result was this: There's no distortion but the result looks blurred and it loses most of the highlights colors. In my opinion it breaks the retro look I needed. The second time I tried Point -> Point and the result was this: Despite the distortion, I think that might be good enough for my needs, although it does look better as a still image than in motion. To demonstrate, here's a video of the effect, although YouTube filtered the pixels out of it: http://youtu.be/hqokk58KFmI However, I'll leave the question open for a few more days in case someone comes up with a better sampling solution that maintains the crisp look while decreasing the amount of distortion when moving.

• conky stopped displaying after daul monitors setup -- works when I detect monitors

  - by synaptik

  I just recently installed Ubuntu 12.04 on a clean install. I previously was using 11.10. I am also using a new laptop with a Dell docking-station and two external monitors. When I try to use the .conkyrc file that I used previously, my conky display simply doesn't show up anywhere. However, after I went to System Settings Displays and made some slight change that caused the monitors to refresh, then conky appeared as it should. Here is my .conkyrc file: background yes use_xft yes xftfont DejaVu Sans Mono:size=8 xftalpha 0.8 out_to_console no update_interval 2.0 total_run_times 0 draw_shades no short_units yes # Create own window instead of using desktop (required in nautilus) own_window yes # If own_window is yes, you may use type normal, desktop or override own_window_type override # Use pseudo transparency with own_window? own_window_transparent yes double_buffer yes default_color f0e68c color1 white color2 AD0303 alignment bottom_left gap_x 2 gap_y 30 no_buffers yes use_spacer right pad_percents 3 xftfont Terminus:size=10 TEXT $stippled_hr cpu1: ${color1}${cpu cpu1}% ${color} cpu2: ${color1}${cpu cpu2}% ${color} load: ${color1}$loadavg ${color} hot proc: ${color1}${top cpu 1}% - ${top name 1}${color} $stippled_hr big proc: ${color1}${top_mem mem_res 1} - ${top_mem name 1}${color} memory: ${color1}$mem/$memmax $memperc%${color} $stippled_hr disk: ${color1}${fs_used /}/${fs_size /}${color} swap: ${color1}${swap}/${swapmax}${color} ${diskiograph_read 15,120 color1 0077ff 750} ${diskiograph_write 15,120 color1 0077ff 750} $stippled_hr download: ${color1}${downspeed wlan0} /s${color} ${downspeedgraph eth0 20,120 104E8B 0077ff} upload: ${color1}${upspeed wlan0} /s${color} ${upspeedgraph eth0 20,120 104E8B 0077ff} How can I fix it so that I don't have to tamper with the Displays settings in order for conky to show up?

• How to make a legacy system time-zone sensitive?

  - by Jerry Dodge

  I need to implement time zones in a very large and old Delphi system, where there's a central SQL Server database and possibly hundreds of client installations around the world in different time zones. The application already interacts with the database by only using the date/time of the database server. So, all the time stamps saved in both the database and on the client machines are the date/time of the database server when it happened, never the time of the client machine. So, when a client is about to display the date/time of something (such as a transaction) which is coming from this database, it needs to show the date/time converted to the local time zone. This is where I get lost. I would naturally assume there should be something in SQL to recognize the time zone and convert a DateTime field dynamically. I'm not sure if such a thing exists though. If so, that would be perfect, but if not, I need to figure out another way. This Delphi system (multiple projects) utilizes the SQL Server database using ADO components, VCL data-aware controls, and QuickReports (using data sources). So, there's many places where the data goes directly from the database query to rendering on the screen, without any code to actually put this data on the screen. In the end, I need to know when and how should I get the properly converted time? What is the proper way to ensure that I handle Dates and Times correctly in a legacy application?

• How do I enable greedy MigrationHeuristic in Karmic?

  - by Matthew

  My laptop performs very poorly for 2d graphics. For example, Docky's zoom effect and compiz effects are very choppy. In Jaunty, I was able to fix this by adding the following line under the "Device" section in my xorg.conf: Option "MigrationHeuristic" "greedy" In Karmic, there is no xorg.conf by default, so I copied my old one (from Jaunty). However, everything is still slow. Here is my xorg.conf: Section "Device" Identifier "Configured Video Device" Option "MigrationHeuristic" "greedy" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection From googling about, it sounds like "MigrationHeuristic" is only an option for the "EXA" mode, while Karmic has switched the intel driver to "UXA". So I tried adding this line under the "Device" section: Option "AccelMethod" "exa" But this didn't help.

• Text Terminal Hardware (for Linux)

  - by DLH

  Is there any way to obtain a hardware text terminal (preferably small in size) with a screen and a keypad to connect to a Linux machine (preferably via usb)? I'd like to be able to log into a command line and do some work there while simultaneously running a graphical environment on the main display. It seems like there should be some kind of lcd screen and qwerty keypad device designed for this purpose. Does this exist, and how do I get one? Edit: I'd be happy with a small networked device as well, as long as I could get a remote terminal into my computer.

• Software for making video tutorial

  - by Ben

  I'm looking for a good video tutorial software. It shouldn't be very complicated. It should be very easy to zoom in on specific locations on screen, as well as make highlights on screen. I have Camtasia Studio, but can't figure out how to do this. This functionality looks ridiculously complicated. http://www.techsmith.com/learn/camtasia/5/editing/zoom-n-pan.asp Free is preferred though low cost is OK too. I have both Mac and Windows. Thanks

• Macbook Pro 13" Retina (10,2): Keyboard and Touchpad don't work

  - by Dirk

  I'm dealing with Ubuntu since about 5 years and installed it on several laptops. Now I'm stuck when trying to install Ubuntu 12.04.1 on a brand new Macbook Pro 13" Retina (10,2). I sucessfully can start Ubuntu from an USB stick, the Ubuntu desktop is visible, a mouse cursor is visible. But there is no respond to keyboard or touchpad input. So I cannot really install Ubuntu on the Macbook. The details of my approach: Prepare an empty USB stick Download "ISO 2 USB EFI Booter for Mac" and copy the file bootX64.efi to the USB drive as /efi/boot/bootX64.efi. Download Ubuntu 12.04.1 Desktop for Mac from http://cdimage.ubuntu.com/releases/1-amd64+mac.iso and copy the iso the USB drive as /efi/boot/boot.iso Put the USB stick into the Macbook Press and hold the "alt" button while switching the Macbook on Select "EFI Boot" from the boot menu that appears and press the Return / Enter key Immediately a black terminal screen appears with the headline "Welcome to the Ubuntu ISO << - EFI booter". 30 seconds later the familiar Ubuntu startup graphics screen is showing. Further 20 seconds later Ubuntu has started and the desktop is visible - in wonderfully fine resolution Now the computer does not respond to any actions on the touchpad nor the keyboard Who did install Ubuntu on this Macbook Pro 13" Retina (10,2) successfully? On this site https://help.ubuntu.com/community/MacBookPro this unit is not listed yet, anyway. Any help would be greatly appreciated! Dirk

• Formatted USB flash drive with Disk Utility on Mac and now it is not recognized on any Mac or Windows machine

  - by Željko Filipin

  I have formatted Canyon CN-MP4A USB flash drive with Disk Utility on Mac and now it is not recognized on any Mac or Windows machine. I have formatted with Disk Utility > drive > Erease > Format > MS-DOS (FAT). Now when I plug it in any Mac or Windows machine, nothing happens. Like nothing is plugged in. It has a screen, and I was able to format it directly from the device before, but now when I turn it on, welcome screen appears, but nothing else. I can not get to the menu. Is there a way I can format it? I am looking for the answer on the internet, but no luck so far.
