• Compiz and Clearlooks window border breaks active/inactive title bars

  - by jimbo1qaz

  When I turn on Compiz with the Compiz tray switcher and I use Clearlooks, Dust Sand, or possibly any title bar style that normally has window icons on right, some window title bars will not change. Instead, they stay selected or unselected randomly. Some windows, like Ubuntu Software Center and CCSM are unaffected. This problem only happens with GTK window manager. I am using the Malteworld compiz ppa for Emerald. The problem does not happen with plain Metacity, or a title bar style that normally has close button on right. Edit: It still happens with Emerald. Reinstalled with upgrade option (yeah, 11.04 to 11.04) and still same problem. So maybe faulty package?

• Are your personal insecurities screwing up your internal communications?

  - by Lucy Boyes

  I do some internal comms as part of my job. Quite a lot of it involves talking to people about stuff. I’m spending the next couple of weeks talking to lots of people about internal comms itself, because we haven’t done a lot of audience/user feedback gathering, and it turns out that if you talk to people about how they feel and what they think, you get some pretty interesting insights (and an idea of what to do next that isn’t just based on guesswork and generalising from self). Three things keep coming up from talking to people about what we suck at  in terms of internal comms. And, as far as I can tell, they’re all examples where personal insecurity on the part of the person doing the communicating makes the experience much worse for the people on the receiving end. 1. Spending time telling people how you’re going to do something, not what you’re doing and why Imagine you’ve got to give an update to a lot of people who don’t work in your area or department but do have an interest in what you’re doing (either because they want to know because they’re curious or because they need to know because it’s going to affect their work too). You don’t want to look bad at your job. You want to make them think you’ve got it covered – ideally because you do*. And you want to reassure them that there’s lots of exciting work going on in your area to make [insert thing of choice] happen to [insert thing of choice] so that [insert group of people] will be happy. That’s great! You’re doing a good job and you want to tell people about it. This is good comms stuff right here. However, you’re slightly afraid you might secretly be stupid or lazy or incompetent. And you’re exponentially more afraid that the people you’re talking to might think you’re stupid or lazy or incompetent. Or pointless. Or not-adding-value. Or whatever the thing that’s the worst possible thing to be in your company is. So you open by mentioning all the stuff you’re going to do, spending five minutes or so making sure that everyone knows that you’re DOING lots of STUFF. And the you talk for the rest of the time about HOW you’re going to do the stuff, because that way everyone will know that you’ve thought about this really hard and done tons of planning and had lots of great ideas about process and that you’ve got this one down. That’s the stuff you’ve got to say, right? To prove you’re not fundamentally worthless as a human being? Well, maybe. But probably not. See, the people who need to know how you’re going to do the stuff are the people doing the stuff. And those are the people in your area who you’ve (hopefully-please-for-the-love-of-everything-holy) already talked to in depth about how you’re going to do the thing (because else how could they help do it?). They are the only people who need to know the how**. It’s the difference between strategy and tactics. The people outside of your bubble of stuff-doing need to know the strategy – what it is that you’re doing, why, where you’re going with it, etc. The people on the ground with you need the strategy and the tactics, because else they won’t know how to do the stuff. But the outside people don’t really need the tactics at all. Don’t bother with the how unless your audience needs it. They probably don’t. It might make you feel better about yourself, but it’s much more likely that Bob and Jane are thinking about how long this meeting has gone on for already than how personally impressive and definitely-not-an-idiot you are for knowing how you’re going to do some work. Feeling marginally better about yourself (but, let’s face it, still insecure as heck) is not worth the cost, which in this case is the alienation of your audience. 2. Talking for too long about stuff This is kinda the same problem as the previous problem, only much less specific, and I’ve more or less covered why it’s bad already. Basic motivation: to make people think you’re not an idiot. What you do: talk for a very long time about what you’re doing so as to make it sound like you know what you’re doing and lots about it. What your audience wants: the shortest meaningful update. Some of this is a kill your darlings problem – the stuff you’re doing that seems really nifty to you seems really nifty to you, and thus you want to share it with everyone to show that you’re a smart person who thinks up nifty things to do. The downside to this is that it’s mostly only interesting to you – if other people don’t need to know, they likely also don’t care. Think about how you feel when someone is talking a lot to you about a lot of stuff that they’re doing which is at best tangentially interesting and/or relevant. You’re probably not thinking that they’re really smart and clearly know what they’re doing (unless they’re talking a lot and being really engaging about it, which is not the same as talking a lot). You’re probably thinking about something totally unrelated to the thing they’re talking about. Or the fact that you’re bored. You might even – and this is the opposite of what they’re hoping to achieve by talking a lot about stuff – be thinking they’re kind of an idiot. There’s another huge advantage to paring down what you’re trying to say to the barest possible points – it clarifies your thinking. The lightning talk format, as well as other formats which limit the time and/or number of slides you have to say a thing, are really good for doing this. It’s incredibly likely that your audience in this case (the people who need to know some things about your thing but not all the things about your thing) will get everything they need to know from five minutes of you talking about it, especially if trying to condense ALL THE THINGS into a five-minute talk has helped you get clear in your own mind what you’re doing, what you’re trying to say about what you’re doing and why you’re doing it. The bonus of this is that by being clear in your thoughts and in what you say, and in not taking up lots of people’s time to tell them stuff they don’t really need to know, you actually come across as much, much smarter than the person who talks for half an hour or more about things that are semi-relevant at best. 3. Waiting until you’ve got every detail sorted before announcing a big change to the people affected by it This is the worst crime on the list. It’s also human nature. Announcing uncertainty – that something important is going to happen (big reorganisation, product getting canned, etc.) but you’re not quite sure what or when or how yet – is scary. There are risks to it. Uncertainty makes people anxious. It might even paralyse them. You can’t run a business while you’re figuring out what to do if you’ve paralysed everyone with fear over what the future might bring. And you’re scared that they might think you’re not the right person to be in charge of [thing] if you don’t even know what you’re doing with it. Best not to say anything until you know exactly what’s going to happen and you can reassure them all, right? Nope. The people who are going to be affected by whatever it is that you don’t quite know all the details of yet aren’t stupid***. You wouldn’t have hired them if they were. They know something’s up because you’ve got your guilty face on and you keep pulling people into meeting rooms and looking vaguely worried. Here’s the deal: it’s a lot less stressful for everyone (including you) if you’re up front from the beginning. We took this approach during a recent company-wide reorganisation and got really positive feedback. People would much, much rather be told that something is going to happen but you’re not entirely sure what it is yet than have you wait until it’s all fixed up and then fait accompli the heck out of them. They will tell you this themselves if you ask them. And here’s why: by waiting until you know exactly what’s going on to communicate, you remove any agency that the people that the thing is going to happen to might otherwise have had. I know you’re scared that they might get scared – and that’s natural and kind of admirable – but it’s also patronising and infantilising. Ask someone whether they’d rather work on a project which has an openly uncertain future from the beginning, or one where everything’s great until it gets shut down with no forewarning, and very few people are going to tell you they’d prefer the latter. Uncertainty is humanising. It’s you admitting that you don’t have all the answers, which is great, because no one does. It allows you to be consultative – you can actually ask other people what they think and how they feel and what they’d like to do and what they think you should do, and they’ll thank you for it and feel listened to and respected as people and colleagues. Which is a really good reason to start talking to them about what’s going on as soon as you know something’s going on yourself. All of the above assumes you actually care about talking to the people who work with you and for you, and that you’d like to do the right thing by them. If that’s not the case, you can cheerfully disregard the advice here, but if it is, you might want to think about the ways above – and the inevitable countless other ways – that making internal communication about you and not about your audience could actually be doing the people you’re trying to communicate with a huge disservice. So take a deep breath and talk. For five minutes or so. About the important things. Not the other things. As soon as you possibly can. And you’ll be fine.   *Of course you do. You’re good at your job. Don’t worry. **This might not always be true, but it is most of the time. Other people who need to know the how will either be people who you’ve already identified as needing-to-know and thus part of the same set as the people in you’re area you’ve already discussed this with, or else they’ll ask you. But don’t bring this stuff up unless someone asks for it, because most of the people in the audience really don’t care and you’re wasting their time. ***I mean, they might be. But let’s give them the benefit of the doubt and assume they’re not.

• How do I disable the calendar events section in GNOME Shell's clock applet?

  - by Victor

  I'm running gnome-shell 3.2.0 and when I click the clock applet in the middle of the top panel, the following shows up: I have no need for the entire right part, right of the dotted line, which is dedicated to the "Online Accounts" integration with evolution's calendar. Is there a way to remove/disable it, so I can just have the date part of the calendar applet (left of the dotted vertical line)? I just like to browse the dates to see how many days are left in the month and stuff like that. I use Google's web interface for my "Calendaring".

• Tips and Tools for creating Spritesheet animations

  - by Spooks

  I am looking for a tool that I can use to create sprite sheet easily. Right now I am using Illustrator, but I can never get the center of the character in the exact position, so it looks like it is moving around(even though its always in one place), while being loop through the sprite sheet. Is there any better tools that I can be using? Also what kind of tips would you give for working with a sprite sheet? Should I create each part of the character in individual layers (left arm, right arm, body, etc.) or everything at once? any other tips would also be helpful! thank you

• Add control to grid from code behind in Silverlight

  - by Emanuele Bartolesi

  In this post I show how you can easily add a control to a silverlight grid layout from code behind. First you draw the grid in the xaml. <Grid x:Name="LayoutRoot" Background="Red"> <Grid.RowDefinitions> <RowDefinition Height="20"> </RowDefinition> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="300"> </ColumnDefinition> </Grid.ColumnDefinitions> </Grid> Now in the page constructor add the following code. public MainPage() { InitializeComponent(); var myButton = new Button { Name = "btnOk", Content = "Ok", }; myButton.SetValue(Grid.RowProperty, 1); myButton.SetValue(Grid.ColumnProperty, 1); myButton.Click += myButton_Click; LayoutRoot.Children.Add(myButton); } Also add the evento of the button. void myButton_Click(object sender, RoutedEventArgs e) { } The code needs no comment because it’s very simple. The only important thing is the method SetValue because it is used to set XAML attribute of element. For a better understanding I have created an example that you can download from here.

• 12.04 update crash, now cannot boot

  - by EdW

  Boot now freezes the system at the "Ubuntu purple screen" with the 5 dots under it. I cannot even CTRL-ALT-F1 to get to an alternate console. Have to push reset button on computer to reboot. After the 12.04 update crash, the system would boot, but I had no icons and no launch bar and errors about missing dependencies. CTRL-ALT-F1 and ran apt-get -f install and it appeared to get the missing packages. I followed with a apt-get update; apt-get upgrade. It appeared to install all of the remaining 12.04 update packages. Rebooted to same blank screen - no icons, but got a compiz error. In console I tried "unity --reset" rebooted ... Nothing ... It's dead in the water. Tried to boot into Recovery Mode - black screen - I cannot even CTRL-ALT-Del - have to push reboot button. Fortunately, I have Mint on another partition and I can access the broken 12.04 partition. Ideas? I can back up all of my folders using Mint, but I would hate to have to do a new install.

• Switching to WIF SessionMode in ASP.NET

  - by Your DisplayName here!

  To make it short: to switch to SessionMode (cache to server) in ASP.NET, you need to handle an event and set a property. Sounds easy – but you need to set it in the right place. The most popular blog post about this topic is from Vittorio. He advises to set IsSessionMode in WSFederationAuthenticationModule_SessionSecurityTokenCreated. Now there were some open questions on forum, like this one. So I decided to try it myself – and indeed it didn’t work for me as well. So I digged a little deeper, and after some trial and error I found the right place (in global.asax): void WSFederationAuthenticationModule_SecurityTokenValidated( object sender, SecurityTokenValidatedEventArgs e) {     FederatedAuthentication.SessionAuthenticationModule.IsSessionMode = true; } Not sure if anything has changed since Vittorio’s post – but this worked for me. While playing around, I also wrote a little diagnostics tool that allows you to look into the session cookie (for educational purposes). Will post that soon. HTH

• Checking whether a specific key was pressed in enchantJS

  - by MxyL

  I am using enchantJS and would like to use the letters and numbers as well as numpad on a keyboard to do different things (eg: hotkeys). From this page http://users.csc.calpoly.edu/~foaad/enchant/guide/playerInput.html By default, enchant.js provides input listeners for six buttons: UP, DOWN, LEFT, RIGHT, A, and B. By default, the directions are bound to the arrow keys. Any of the six buttons may also be bound to any key with an ASCII value. We’ll address that later. So enchant provides the ability to bind keys to different input such as up, down, left, right...but how can I simply check whether the D or X key was pressed, and if so, perform certain actions based on that event?

• Slerping rotation mirrors

  - by Esa

  I rotate my game character to watch at the target using the following code: transform.rotation = Quaternion.Slerp(startQuaternion, lookQuaternion, turningNormalizer*turningSpeed/10f) startQuaternion is the character's current rotation when a new target is given. lookQuaternion is the direction the character should look at and it's set like this: destinationVector = currentWaypoint.transform.position - transform.position; lookQuaternion = Quaternion.LookRotation(destinationVector, Vector3.up); turningNormalizer is just Time.deltaTime incremented and turningSpeed is a static value given in the editor. The problem is that while the character turns as it should most of the time, it has problems when it has to do close to 180 degrees. Then it at times jitters and mirrors the rotation: In this poorly drawn image the character(on the right) starts to turn towards the circle on the left. Instead of just turning either through left or right it starts this "mirror dance": It starts to rotate towards the new facing Then it suddenly snaps to the same angle but on other side and keeps rotating It does this "mirroring" so long until it looks at the target. Is this a thing with quaternions, slerping/lerping or something else?

• Fujitsu Siemens V6535 laptop doesn't wake up - crash when going into standby?

  - by marc

  I'm having trouble with my laptop (Fujitsu Siemens model V6535). It runs Windows 7, and after I upgraded from Vista I've noticed something that makes me really angry. When my laptop goes into Standby, the power LED changes to red and starts blinking (standby mode). When I push the power button to wake it up it, the blinking LED changes to green but nothing else happens. Nothing on the display, no HDD sound. When I press the power button for a few seconds and then try turn it on again, it doesn't display anything. I have to unplug the charger, shut it off, and power it on again without the power cable. Then it starts working. A few days ago I upgraded the BIOS to the newest version, but it doesn't help. Does anyone have any idea what can be wrong?

• Color Picking Troubles - LWJGL/OpenGL

  - by Tom Johnson

  I'm attempting to check which object the user is hovering over. While everything seems to be just how I'd think it should be, I'm not able to get the correct color due to the second time I draw (without picking colors). Here is my rendering code: public void render() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); camera.applyTranslations(); scene.pick(); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); camera.applyTranslations(); scene.render(); } And here is what gets called on each block/tile on "scene.pick()": public void pick() { glColor3ub((byte) pickingColor.x, (byte) pickingColor.y, (byte) pickingColor.z); draw(); glReadBuffer(GL_FRONT); ByteBuffer buffer = BufferUtils.createByteBuffer(4); glReadPixels(Mouse.getX(), Mouse.getY(), 1, 1, GL_RGBA, GL_UNSIGNED_BYTE, buffer); int r = buffer.get(0) & 0xFF; int g = buffer.get(1) & 0xFF; int b = buffer.get(2) & 0xFF; if(r == pickingColor.x && g == pickingColor.y && b == pickingColor.z) { hovered = true; } else { hovered = false; } } I believe the problem is that in the method of each tile/block called by scene.pick(), it is reading the color from the regular drawing state, after that method is called somehow. I believe this because when I remove the "glReadBuffer(GL_FRONT)" line from the pick method, it seems to almost fix it, but then it will also select blocks behind the one you are hovering as it is not only looking at the front. If you have any ideas of what to do, please be sure to reply!/ EDIT: Adding scene.render(), tile.render(), and tile.draw() scene.render: public void render() { for(int x = 0; x < tiles.length; x++) { for(int z = 0; z < tiles.length; z++) { tiles[x][z].render(); } } } tile.render: public void render() { glColor3f(color.x, color.y, color.z); draw(); if(hovered) { glColor3f(1, 1, 1); glPolygonMode(GL_FRONT_AND_BACK, GL_LINE); draw(); glPolygonMode(GL_FRONT_AND_BACK, GL_FILL); } } tile.draw: public void draw() { float x = position.x, y = position.y, z = position.z; //Top glBegin(GL_QUADS); glVertex3f(x, y + size, z); glVertex3f(x + size, y + size, z); glVertex3f(x + size, y + size, z + size); glVertex3f(x, y + size, z + size); glEnd(); //Left glBegin(GL_QUADS); glVertex3f(x, y, z); glVertex3f(x + size, y, z); glVertex3f(x + size, y + size, z); glVertex3f(x, y + size, z); glEnd(); //Right glBegin(GL_QUADS); glVertex3f(x + size, y, z); glVertex3f(x + size, y + size, z); glVertex3f(x + size, y + size, z + size); glVertex3f(x + size, y, z + size); glEnd(); } (The game is like an isometric game. That's why I only draw 3 faces.)

• How to configure Logitech Marble trackball

  - by user27189

  You can configure it using xinput. I tested this in 11.10 and it works very nicely. This selection is from "Ubuntuwiki" Avoid using Hal for this release because it has known issues. Put the following into terminal, using gedit: Edit $HOME/bin/trackball.sh using this command: gedit $HOME/bin/trackball.sh Then paste this into the file: #!/bin/bash dev="Logitech USB Trackball" we="Evdev Wheel Emulation" xinput set-int-prop "$dev" "$we Button" 8 8 xinput set-int-prop "$dev" "$we" 8 1 # xinput set-int-prop "$dev" "$we" 8 1 # xinput set-int-prop "$dev" "$we Button" 8 9 # xinput set-int-prop "$dev" "$we X Axis" 8 6 7 # xinput set-int-prop "$dev" "$we Y Axis" 8 4 5 # xinput set-int-prop "$dev" "Drag Lock Buttons" 8 8 Make sure trackball.sh begins with #!/bin/bash. Make the script executable by running this: chmod +x $HOME/bin/trackball.sh` Add the following lines to $HOME/.bashrc, using gedit $HOME/.bashrc and put this in the file even if it is empty: xmodmap $HOME/.Xmodmap > /dev/null 2>&1 $HOME/bin/trackball.sh Edit $HOME/.Xmodmap using: gedit $HOME/.Xmodmap pointer = 1 8 3 4 5 6 7 9 Log out and back in and viola!

• Developing Schema Compare for Oracle (Part 6): 9i Query Performance

  - by Simon Cooper

  All throughout the EAP and beta versions of Schema Compare for Oracle, our main request was support for Oracle 9i. After releasing version 1.0 with support for 10g and 11g, our next step was then to get version 1.1 of SCfO out with support for 9i. However, there were some significant problems that we had to overcome first. This post will concentrate on query execution time. When we first tested SCfO on a 9i server, after accounting for various changes to the data dictionary, we found that database registration was taking a long time. And I mean a looooooong time. The same database that on 10g or 11g would take a couple of minutes to register would be taking upwards of 30 mins on 9i. Obviously, this is not ideal, so a poke around the query execution plans was required. As an example, let's take the table population query - the one that reads ALL_TABLES and joins it with a few other dictionary views to get us back our list of tables. On 10g, this query takes 5.6 seconds. On 9i, it takes 89.47 seconds. The difference in execution plan is even more dramatic - here's the (edited) execution plan on 10g: -------------------------------------------------------------------------------| Id | Operation | Name | Bytes | Cost |-------------------------------------------------------------------------------| 0 | SELECT STATEMENT | | 108K| 939 || 1 | SORT ORDER BY | | 108K| 939 || 2 | NESTED LOOPS OUTER | | 108K| 938 ||* 3 | HASH JOIN RIGHT OUTER | | 103K| 762 || 4 | VIEW | ALL_EXTERNAL_LOCATIONS | 2058 | 3 ||* 20 | HASH JOIN RIGHT OUTER | | 73472 | 759 || 21 | VIEW | ALL_EXTERNAL_TABLES | 2097 | 3 ||* 34 | HASH JOIN RIGHT OUTER | | 39920 | 755 || 35 | VIEW | ALL_MVIEWS | 51 | 7 || 58 | NESTED LOOPS OUTER | | 39104 | 748 || 59 | VIEW | ALL_TABLES | 6704 | 668 || 89 | VIEW PUSHED PREDICATE | ALL_TAB_COMMENTS | 2025 | 5 || 106 | VIEW | ALL_PART_TABLES | 277 | 11 |------------------------------------------------------------------------------- And the same query on 9i: -------------------------------------------------------------------------------| Id | Operation | Name | Bytes | Cost |-------------------------------------------------------------------------------| 0 | SELECT STATEMENT | | 16P| 55G|| 1 | SORT ORDER BY | | 16P| 55G|| 2 | NESTED LOOPS OUTER | | 16P| 862M|| 3 | NESTED LOOPS OUTER | | 5251G| 992K|| 4 | NESTED LOOPS OUTER | | 4243M| 2578 || 5 | NESTED LOOPS OUTER | | 2669K| 1440 ||* 6 | HASH JOIN OUTER | | 398K| 302 || 7 | VIEW | ALL_TABLES | 342K| 276 || 29 | VIEW | ALL_MVIEWS | 51 | 20 ||* 50 | VIEW PUSHED PREDICATE | ALL_TAB_COMMENTS | 2043 | ||* 66 | VIEW PUSHED PREDICATE | ALL_EXTERNAL_TABLES | 1777K| ||* 80 | VIEW PUSHED PREDICATE | ALL_EXTERNAL_LOCATIONS | 1744K| ||* 96 | VIEW | ALL_PART_TABLES | 852K| |------------------------------------------------------------------------------- Have a look at the cost column. 10g's overall query cost is 939, and 9i is 55,000,000,000 (or more precisely, 55,496,472,769). It's also having to process far more data. What on earth could be causing this huge difference in query cost? After trawling through the '10g New Features' documentation, we found item 1.9.2.21. Before 10g, Oracle advised that you do not collect statistics on data dictionary objects. From 10g, it advised that you do collect statistics on the data dictionary; for our queries, Oracle therefore knows what sort of data is in the dictionary tables, and so can generate an efficient execution plan. On 9i, no statistics are present on the system tables, so Oracle has to use the Rule Based Optimizer, which turns most LEFT JOINs into nested loops. If we force 9i to use hash joins, like 10g, we get a much better plan: -------------------------------------------------------------------------------| Id | Operation | Name | Bytes | Cost |-------------------------------------------------------------------------------| 0 | SELECT STATEMENT | | 7587K| 3704 || 1 | SORT ORDER BY | | 7587K| 3704 ||* 2 | HASH JOIN OUTER | | 7587K| 822 ||* 3 | HASH JOIN OUTER | | 5262K| 616 ||* 4 | HASH JOIN OUTER | | 2980K| 465 ||* 5 | HASH JOIN OUTER | | 710K| 432 ||* 6 | HASH JOIN OUTER | | 398K| 302 || 7 | VIEW | ALL_TABLES | 342K| 276 || 29 | VIEW | ALL_MVIEWS | 51 | 20 || 50 | VIEW | ALL_PART_TABLES | 852K| 104 || 78 | VIEW | ALL_TAB_COMMENTS | 2043 | 14 || 93 | VIEW | ALL_EXTERNAL_LOCATIONS | 1744K| 31 || 106 | VIEW | ALL_EXTERNAL_TABLES | 1777K| 28 |------------------------------------------------------------------------------- That's much more like it. This drops the execution time down to 24 seconds. Not as good as 10g, but still an improvement. There are still several problems with this, however. 10g introduced a new join method - a right outer hash join (used in the first execution plan). The 9i query optimizer doesn't have this option available, so forcing a hash join means it has to hash the ALL_TABLES table, and furthermore re-hash it for every hash join in the execution plan; this could be thousands and thousands of rows. And although forcing hash joins somewhat alleviates this problem on our test systems, there's no guarantee that this will improve the execution time on customers' systems; it may even increase the time it takes (say, if all their tables are partitioned, or they've got a lot of materialized views). Ideally, we would want a solution that provides a speedup whatever the input. To try and get some ideas, we asked some oracle performance specialists to see if they had any ideas or tips. Their recommendation was to add a hidden hook into the product that allowed users to specify their own query hints, or even rewrite the queries entirely. However, we would prefer not to take that approach; as well as a lot of new infrastructure & a rewrite of the population code, it would have meant that any users of 9i would have to spend some time optimizing it to get it working on their system before they could use the product. Another approach was needed. All our population queries have a very specific pattern - a base table provides most of the information we need (ALL_TABLES for tables, or ALL_TAB_COLS for columns) and we do a left join to extra subsidiary tables that fill in gaps (for instance, ALL_PART_TABLES for partition information). All the left joins use the same set of columns to join on (typically the object owner & name), so we could re-use the hash information for each join, rather than re-hashing the same columns for every join. To allow us to do this, along with various other performance improvements that could be done for the specific query pattern we were using, we read all the tables individually and do a hash join on the client. Fortunately, this 'pure' algorithmic problem is the kind that can be very well optimized for expected real-world situations; as well as storing row data we're not using in the hash key on disk, we use very specific memory-efficient data structures to store all the information we need. This allows us to achieve a database population time that is as fast as on 10g, and even (in some situations) slightly faster, and a memory overhead of roughly 150 bytes per row of data in the result set (for schemas with 10,000 tables in that means an extra 1.4MB memory being used during population). Next: fun with the 9i dictionary views.

• Software for capturing still image snapshots from video input

  - by cantabilesoftware

  What software is available that will let me watch video from a USB video capture device at full PAL/NTSC resolution and capture a still image at a button press? More info: I'm using a KaiserBaas USB capture device (http://www.kaiserbaas.com/kaiser-baas-product-page/converters/video-to-dvd-maker), and want to capture screen shots from a PS2 connected to it. I'd like to play the game at the full PS2 resolution and capture certain scenes. The device has a one-touch snapshot button on it, but I can't seem to make it work and there's no mention of it anywhere in the documentation. The device works and the video appears in Power Producer (the included software), but I think it previews it smaller than the full resolution. I could print screen it, but having to crop will be a pain.

• What's the best way to manage error logging for exceptions?

  - by Peter Boughton

  Introduction If an error occurs on a website or system, it is of course useful to log it, and show the user a polite message with a reference code for the error. And if you have lots of systems, you don't want this information dotted around - it is good to have a single centralised place for it. At the simplest level, all that's needed is an incrementing id and a serialized dump of the error details. (And possibly the "centralised place" being an email inbox.) At the other end of the spectrum is perhaps a fully normalised database that also allows you to press a button and see a graph of errors per day, or identifying what the most common type of error on system X is, whether server A has more database connection errors than server B, and so on. What I'm referring to here is logging code-level errors/exceptions by a remote system - not "human-based" issue tracking, such as done with Jira,Trac,etc. Questions I'm looking for thoughts from developers who have used this type of system, specifically with regards to: What are essential features you couldn't do without? What are good to have features that really save you time? What features might seem a good idea, but aren't actually that useful? For example, I'd say a "show duplicates" function that identifies multiple occurrence of an error (without worrying about 'unimportant' details that might differ) is pretty essential. A button to "create an issue in [Jira/etc] for this error" sounds like a good time-saver. Just to re-iterate, what I'm after is practical experiences from people that have used such systems, preferably backed-up with why a feature is awesome/terrible. (If you're going to theorise anyway, at the very least mark your answer as such.)

• "Unable to mount location. Failed to mount Windows share" error when trying to share folders

  - by paulus_almighty

  I have two Ubuntu machines both on 11.10 I want to share folders from one to the other. If, on the server machine, (in Nautilus) I right click on the folders and click Properties Share Share this folder Create share. Then on the client I'm prompted for a username and password. My username and password does not work. If I select "Guest access" check box then I get "Unable to mount location. Failed to mount Windows share" This should be straightforward, right?

• the window of calender is out of the screen

  - by draw

  hi, I've been using a external 21.5' monitor for my laptop of 12.1' monitor, and moved my top panel to the right and add a new panel to the bottom edge of the screen. A screenshot of the right part of my desktop is here: http://i.imgur.com/kOHwT.png As you see, The window of the calender is out of the screen. The alt+left mouse button did not work. How do you move the calender window? update: I managed to come up with a solution to get the window or panel of cal in the screen. Just remove the panel of clock and re-add it. But unfortunately, the preferences are lost. You have to reset the preferences, such as locations... but after re-adding 2 locations, the window of cal panel was just shown as the same of the previous screenshot before.

• How to prevent window list "confusion" when detaching eclipse views?

  - by amotzg

  I'm detaching eclipse views to float on my other screen in order to get more coding space on the first screen. When doing that, the detached windows appear in ubuntu's window list applet with the eclipse icon but with no title. Then, when pushing the main eclipse button on the window list, one of the detached views will get to front but not the main eclipse window. When using Alt+tab I can also see the extra eclipse icons but choosing the correct one for the main window works and make it the active window while also showing all detached childs. Other applications behave as expected, e.g. gimp floating panels don't show on the windows list and this is also the case with SlickEdit, Firefox child windows all show on window list but gets the focus correctly, etc. I can see the the workspace switcher show my two screens but in 'Monitor preferences' I see my two screens as one big screen. I'm working with ubuntu 10.04.4 under a VMware Workstation 7.1.3 build-324285. 'uname -a' output: Linux ubuntu 2.6.32-40-generic #87-Ubuntu SMP Tue Mar 6 00:56:56 UTC 2012 x86_64 GNU/Linux The desktop screen shot with the problem, ununtu's version, and Monitor preferences. How can I solve it and make only the main window show in window list or at least get activated when pushing it's button on the window list?

• SEI Turns Software Architecture into a Game

  - by Bob Rhubart-Oracle

  "Architecture is the decisions that you wish you could get right early in a project." -- Ralph E. Johnson Unless you can see into the future, getting those decisions right comes down to a collection of hard choices. But the Software Engineering Institute (SEI) of Carnegie Mellon University has turned those hard choices into a game. Literally. According to the SEI website: The Hard Choices game is a simulation of the software development cycle meant to communicate the concepts of uncertainty, risk, options, and technical debt. In the quest to become market leader, players race to release a quality product to the marketplace. By the end of the game, everyone has experienced the implications of investing effort to gain an advantage or of paying a price to take shortcuts, as they employ design strategies in the face of uncertainty.   Check it out for yourself: Download the Hard Choices Board Game Download the companion white paper: The Hard Choices Game Explained

• Is hierarchical product backlog a good idea in TFS 2012-2013?

  - by Matías Fidemraizer

  I'd like to validate I'm not in the wrong way. My team project is using Visual Studio Scrum 2.x. Since each area/product has a lot of kind of requirements (security, user interface, HTTP/REST services...), I tried to manage this creating "parent backlogs" which are "open forever" and they contain generic requirements. Those parent backlogs have other "open forever" backlogs, and/or sprint backlogs. For example: HTTP/REST Services (forever) ___ Profiles API (forever) ________ POST profile (forever) _______________ We need a basic HTTP/REST profiles' API to register new user profiles (sprint backlog) Is it the right way of organizing the product backlog? Note: I know there're different points of view and that would be right for some and wrong for others. I'm looking for validation about if this is a possible good practice on TFS with Visual Studio Scrum.
