  • How to elevate engineering culture at large corporations?

    - by davidk01
    One thing I have realized working at a large corporation is that it doesn't matter how smart you are because if everyone else doesn't see the value in what you are doing then you are not going to get very far. It's much harder to convince 1000 people that a certain part of the software stack should be in groovy than it is to convince 10 people of the same thing. I'm curious how people go about elevating the engineering culture at large corporations because I've been running into walls left and right and I would like to be more proactive about how I go about it. I have been advocating tech talks and tech demos along with code reviews as potential solutions. Do people have other suggestions? Note that 1000 people and groovy are just representative examples. I am not married to groovy or any other language and 1000 people is meant to indicate large scale and how to go about teaching a large group of people about best practices and engineering principles in general.

  • managing information/functionality on shared common project classes

    - by ilansch
    In my company, we have a common solution the contains common projects (2 projects so far, one for .net 3.5 and one for .net 4.5). My main problem is that during time, a lot of code is added, for example hosting a process as windows service is a class called ServiceManagement, But no one but the developer knows it, and if someone wants to use this shared class, he does not know it exist. So i am looking for a way to document and manage all the classes with tags, a 3rd party util/web util, that i can search for tags and maybe find common classes that i can use (if we keep all our code well-documented). Does anyone familiar with sort of tools ?

  • HybridGraphics vga_switcheroo switch to intel at boot

    - by Jan
    How can I do that? I have followed this https://help.ubuntu.com/community/HybridGraphics but it didn't work I'm getting the error at boot that the /sys/kernel/debug/vgaswitcheroo/switch don't exist , so the problem seems to be that the /sys/kernel/debug don't exist when the grub parameters are processed and it is created after the grub parameter processing. So far I have made an alternative method, which works. In rc.local I granted full access to my user to /sys/kernel/debug then also to /sys/kernel/debug/vgaswitcheroo/switch and then I have made a simple script to switch the graphics to intel and putted it in ~./confif/autostart. The script is executed every time I log in to gnome. It's working however it would be nice if it worked at boot, as is described at that help.ubuntu.com page. Any ideas? Thanks

  • How do you upgrade/remove a side-by-side installation?

    - by d3vid
    I've hit some snags in the last two upgrades (which I've been able to resolve with time, patience and AskUbuntu :) so come 12.04 I'm considering a side-by-side installation. Perhaps even installing a pre-release before that (because virtual machine testing can't reveal hardware-related issues). So, let's say I installed a side-by-side version. As far as I can tell this splits my existing partition and installs a brand new Ubuntu on partition 2. If all goes well, there are no hardware issues, and my favorite apps seem to be working, how do I switch to a one-sided installation? If I can't, how do I do a side-by-side installation the next time? (And, am I crazy to consider using a pre-release version to do a side-by-side installation?)

  • Determine percentage of screen covered by an object without using frustum culling

    - by Meltac
    On the CPU-side of an 3D first-person / ego perspective game I need to check whether what the players currently sees on screen is the inside of a box object defined by world space coordinates (the player might be outside of that box but on screen sees only/mostly the inside of the box, or vice-versa, looks from within the box to the outside). The "casual" way of performing such a check would incorporate frustum culling but such an approach would be hard to achieve with my given set of engine parameters which I'd like to avoid if there is a simpler way. What I actually have at the point where I would like to do the check (high-level script on CPU, not GPU side): Camera world position Camera direction Camera FOV Two Box corner world coordinates (left-bottom-front, right-top-back) What I do not have right away: View frustrum definition (near/far plane or say 6 planes defining frustum) Any specific pixel information (uv, view space position, depth or the like) What I would like to calculate: Percentage of screen "covered" by box. Any hints on how to perform such calculation?

  • System Wide Performance Sanity Check Procedures

    - by user702295
    Do you need to boost your overall implementation performance? Do you need a direction to pinpoint possible performance opportunities? Are you looking for a general performance guide? Try MOS note 69565.1.  This paper describes a holistic methodology that defines a systematic approach to resolve complex Application performance problems.  It has been successfully used on many critical accounts.  The 'end-to-end' tuning approach encompasses the client, network and database and has proven far more effective than isolated tuning exercises.  It has been used to define and measure targets to ensure success.  Even though it was checked for relevance on 13-Oct-2008, the procedure is still very valuable. Regards!

  • PASS: 2013 Summit Location

    - by Bill Graziano
    HQ recently posted a brief update on our search for a location for 2013.  It includes links to posts by four Board members and two community members. I’d like to add my thoughts to the mix and ask you a question.  But I can’t give you a real understanding without telling you some history first. So far we’ve had the Summit in Chicago, San Francisco, Orlando, Dallas, Denver and Seattle.  Each has a little different feel and distinct memories.  I enjoyed getting drinks by the pool in Orlando after the sessions ended.  I didn’t like that our location in Dallas was so far away from all the nightlife.  Denver was in downtown but we had real challenges with hotels.  I enjoyed the different locations.  I always enjoyed the announcement during the third keynote with the location of the next Summit. There are two big events that impacted my thinking on the Summit location.  The first was our transition to the new management company in early 2007.  The event that September in Denver was put on with a six month planning cycle by a brand new headquarters staff.  It wasn’t perfect but came off much better than I had dared to hope.  It also moved us out of the cookie cutter conferences that we used to do into a model where we have a lot more control.  I think you’ll all agree that the production values of our last few Summits have been fantastic.  That Summit also led to our changing relationship with Microsoft.  Microsoft holds two seats on the PASS Board.  All the PASS Board members face the same challenge: we all have full-time jobs and PASS comes in second place professionally (or sometimes further back).  Starting in 2008 we were assigned a liaison from Microsoft that had a much larger block of time to coordinate with us.  That changed everything between PASS and Microsoft.  Suddenly we were talking to product marketing, Microsoft PR, their event team, the Tech*Ed team, the education division, their user group team and their field sales team – locally and internationally.  We strengthened our relationship with CSS, SQLCAT and the engineering teams.  We had exposure at the executive level that we’d never had before.  And their level of participation at the Summit changed from under 100 people to 400-500 people.  I think those 400+ Microsoft employees have value at a conference on Microsoft SQL Server.  For the first time, Seattle had a real competitive advantage over other cities. I’m one that looked very hard at staying in Seattle for a long, long time.  I think those Microsoft engineers have value to our attendees.  I think the increased support that Microsoft can provide when we’re in Seattle has value to our attendees.  But that doesn’t tell the whole story.  There’s a significant (and vocal!) percentage of our membership that wants the Summit outside Seattle.  Post-2007 PASS doesn’t know what it’s like to have a Summit outside of Seattle.  I think until we have a Summit in another city we won’t really know the trade-offs. I think a model where we move every third or every other year is interesting.  But until we have another Summit outside Seattle and we can evaluate the logistics and how important it is to have depth and variety in our Microsoft participation we won’t really know. Another benefit that comes with a move is variety or diversity.  I learn more when I’m exposed to new things and new people.  I believe that moving the Summit will give a different set of people an opportunity to attend. Grant Fritchey writes “It seems that the board is leaning, extremely heavily, towards making it a permanent fixture in Seattle.”  I don’t believe that’s true.  I know there was discussion of that earlier but I don’t believe it’s true now. And that brings me to my question.  Do we announce the city now or do we wait until the 2012 Summit?  I’m happy to announce Seattle vs. not-Seattle as soon as we sign the contract.  But I’d like to leave the actual city announcement until the 2011 Summit.  I like the drama and mystery of it.  I also like that it doesn’t give you a reason to skip a Summit and wait for the next one if it’s closer or back in Seattle.  The other side of the coin is that your planning is easier if you know where it is.  What do you think?

  • Client/Server Application Using Google App Engine

    - by Kevin Zhang
    Can someone please advise me what is the possible solution of using GAE to make a Client/Serer Application? As far as I know, GAE is designed to do web applications. What I want to do is to have a Java Client(Swing based) deployed on a number of computers and deploy the server on GAE. I found an example on GAE website which teaches how to make a SOAP service using GAE, but I don't know whether using SOAP is a good idea for client/server applications. Can someone give me some hints about how to design this system and what technology should be used? Any advices are welcome. Many thanks.

  • How do you turn a cube into a sphere?

    - by Tom Dalling
    I'm trying to make a quad sphere based on an article, which shows results like this: I can generate a cube correctly: But when I convert all the points according to this formula (from the page linked above): x = x * sqrtf(1.0 - (y*y/2.0) - (z*z/2.0) + (y*y*z*z/3.0)); y = y * sqrtf(1.0 - (z*z/2.0) - (x*x/2.0) + (z*z*x*x/3.0)); z = z * sqrtf(1.0 - (x*x/2.0) - (y*y/2.0) + (x*x*y*y/3.0)); My sphere looks like this: As you can see, the edges of the cube still poke out too far. The cube ranges from -1 to +1 on all axes, like the article says. Any ideas what is wrong?

  • Is php|architect any good?

    - by Andrew Heath
    Kind of a hard topic to search for, as architect turns up a lot about software architects instead. After 8 months of PHP self-study, I finally stumbled across the php|architect site. The length of time it took me to find it makes me suspicious of its quality. 3 related questions: do professional PHP coders read/care about php|architect? is it a good source for PHP beginners? assuming yes to either of the above, how far back in the archives to articles remain relevant? (ex: does stuff written about PHP4 still matter?)

  • White Paper on Parallel Processing

    - by Andrew Kelly
      I just ran across what I think is a newly published white paper on parallel  processing in SQL Server 2008 R2. The date is October 2010 but this is the first time I have seen it so I am not 100% sure how new it really is. Maybe you have seen it already but if not I recommend taking a look. So far I haven’t had time to read it extensively but from a cursory look it appears to be quite informative and this is one of the areas least understood by a lot of dba’s. It was authored by Don Pinto...(read more)

  • Integration of advertisement into WP7 apps: Any experiences?

    - by OneWorld
    Has anyone of you guys integrated or is thinking about integrating either admob, MS pubCenter, adwhirl or any other advertising provider into your apps? Please share your experience... Who pays best? Any regulations? Any problems with getting the app approved by Microsoft Market? If you chose Admob: Which plugin do you suggest? This or that or another one? Any experiences in Europe or Germany? (MS pubCenter is US only so far) Edit: I think we discussed enough about acceptance of mobile advertisement. Let's focus now on the questions I asked. Edit 2: Hmm, maybe Stackoverlfow is a better place to discuss question 2-5. Could somebody migrate this one?

  • Why is the console hanging randomly?

    - by Josh M.
    Ubuntu 10.10 Server x64 installed as Virtual Box VM. Fresh install plus postgresql and tomcat6 installed via aptitude. Rebooted the server and now when I run some command the console hangs. For instance, I run "sudo shutdown now" and then nothing happens but I am not returned to the prompt. I hit CTRL+C and nothing happens except ^C appears on the following line. I can type whatever and it will show up inline. I switch to tty2 and try to login and I only get as far as [username][enter] and that console hangs. One other thing - after "sudo reboot" the console appears to hang (just like above) when shutting down tomcat6. Any idea what's going on or what I should check? Thanks!

  • Should I start learning WPF?

    - by questron
    Hi, I've been studying C# for about 2 months so far, I have a few years experience programming however in VBA and VB6, but nothing too in depth (I've written simple tools, but nothing too advanced). I am very interested in WPF and I was wondering whether it would be too early for me to start learning how to use it? For reference, I am about 400 pages into 'Head First C#' and I've written a program that can quickly tag image files for moving into a predefined folder or to delete (Allows the user to pull images off of a camera memory card and sort VERY quickly). That's the most advanced app I've written.

  • How do you go about training a replacement?

    - by SnOrfus
    I recently asked about leaving a position and got a lot of great answers. One of the common threads was that being around to train the new person would be expected and could go a long way. Now considering that (I think) most people don't stay at a company for a long time after they've given notice, and it will take time for the company to interview/hire one - that leaves for a short amount of time to get someone up to speed. I've also never trained anyone before. I did a bunch of tutoring in University and College, but teaching a language/technology is far different from training someone to replace you on your job. So the question is: how do you go about training someone to replace you in a, potentially, short amount of time?

  • Hard-copy approaches to time tracking

    - by STW
    I have a problem: I suck at tracking time-on-task for specific feature/defects/etc while coding them. I tend to jump between tasks a fair bit (partly due to the inherit juggling required by professional software development, partly due to my personal tendancy to focus on the code itself and not the business process around code). My personal preference is for a hard-copy system. Even with gabillions of pixels of real-estate on-screen I find it terribly distracting to keep a tracking window convienient; either I forget about it or it gets in my ways. So, looking for suggestions on time-tracking. My only requirement is a simple system to track start/stop times per task. I've considered going as far as buying a time-clock and giving each ticket a dedicated time-card. When I start working on it, punch-in; when done working, punch-out.

  • Are there plans to use the empty space in the SoundMenu?

    - by Kyle Clarke
    There seems to be roughly 4 lines of space next to the album art. However only 3 are used. Song Title Artist Album If nothing is planned for the 4th line. I propose that it is used for track time/length. This way you can tell how far along a song is without the need of a scrub bar. Unrelated, but I feel that the play-lists section should display how many songs are in that play list. Some of my play lists have no songs, and without realising this, it seems like a bug that the songs wont play.

  • Find vertices of a convex hull

    - by Jeff Bullard
    I am attempting to do this within CGAL. From a 3D point cloud, find the convex hull, then loop over the finite facets of the convex hull and print each facet's vertices. It seems like there should be a straightforward way to do this; I would have expected that 3D polyhedra would own a vector of facet objects, each of which in turn would own a vector of its edges, each of which in turn would own a vector of its vertices, and that their would be some access through this hierarchy using iterators. But so far I have been unable to find a simple way to navigate through this hierarchy (if it exists).

  • What's the default traditional Chinese font?

    - by janoChen
    The only fonts that can render Chinese text are: WenQuanYi Micro Hei, WenQuanYi Micro Hei Mono, Droid Sans (I think is unicode), FreeSans (I think is unicode too). Changing Chinese text to Sans, FreeSans, Droid Sans render the same font). WenQuanYi Micro Hei, WenQuanYi Micro Hei Mono render 'bolder' Chinese text. EDIT: What I discovered so far: Is not WenQuanYi Micro Hei, WenQuanYi Micro Hei, Droid Sans Fallback (Droid with CJK support). It can only be FreeSans, or Deja vu Sans. I'm not sure which one is being used as default one (clean installation) Any idea?

  • What programming Language Would you learn to Re-engineer USB Devices? [closed]

    - by user70113
    Currently Work in IT support and am retraining in electrical engineering / electronics, I am also interested in Reverse Engineering which language would be best for Hardware RE, I have seen a few sources say C, C++ and Python? I am not familiar with Linux, but installed Ubuntu to learn with. I am not a programmer. Far from it. But, I can understand enough basic VB,Java and PHP to edit it for simple things. One of my immediate projects would be to learn to reverse engineer USB devices and write my own low level drivers. I know there are porting kits, but I really want to know it from the ground up. Thanks for any advise folks Most Appreciated.

  • Best tools to build an auction website

    - by Daniel Loureiro
    Can I get your feedback on the best tools to build an auction website with the following features: The site takes a commission (like 5%) on each transaction Each user can assign a rating (like 4.5 stars) to his completed transaction, and comment on the seller's profile. Accept payments in paypal and credit card I've been looking into Joomla! and JomSocial but they haven't convinced me much so far. I have some programming experience in C, Python and Java. If no CMS tools are of use I'd appreaciate if you could tell the best route to take in programming to get the auction site done.

  • How to change speed without changing path travelled?

    - by Ben Williams
    I have a ball which is being thrown from one side of a 2D space to the other. The formula I am using for calculating the ball's position at any one point in time is: x = x0 + vx0*t y = y0 + vy0*t - 0.5*g*t*t where g is gravity, t is time, x0 is the initial x position, vx0 is the initial x velocity. What I would like to do is change the speed of this ball, without changing how far it travels. Let's say the ball starts in the lower left corner, moves upwards and rightwards in an arc, and finishes in the lower right corner, and this takes 5s. What I would like to be able to do is change this so it takes 10s or 20s, but the ball still follows the same curve and finishes in the same position. How can I achieve this? All I can think of is manipulating t but I don't think that's a good idea. I'm sure it's something simple, but my maths is pretty shaky.

  • Is it normal to not have desktop effects after installing on an Asus N53S?

    - by Fabzter
    I've just installed 11.10 and so far so great, except I just discovered (after looking at another installation) I'm missing some effects. First of all, I am using unity 3d (I chose ubuntu at the login menu), and have already the correct nvidia drivers. Yet, my launcher is the same from unity 2d, the same as the app switcher, and when dragging windows to screen corners, they don't get grabbed. This "error" was present since the begining, so I was not able to detect it. Please help, I want to have an ubuntu experience as nice as everyone else. EDIT 1: I'm using an Asus N53S. My graphic card is Nvidia geforce GT540M. It says cuda, if that matters.

  • how do you read from system.out in Java [closed]

    - by Dan
    I'm trying to create a word scramble game and so far I have taken a vector of randomly assorted strings that contains both words and hints and split them into two vectors. I have randomly scrambled the word and set this all up in text boxes. Right now I'm stuck because I have a text box that takes input but I'm not sure how to read that in? I want the user to type the unscrambled word into the text box and have it calculate as correct and move on to the next word immediately. I also don't know how to get the keys working. I want the "?" character to be the hint button that shows the hint. At the moment the hint box works if I type the question mark in using the System.in but it doesn't work if I type it directly in to the text box. The characters are showing up in the text box but nothing is working after that.
