• @CodeStock 2012 Review: Leon Gersing ( @Rubybuddha ) - "You"

  "YOU"Speaker: Leon GersingTwitter: @Rubybuddha Site: http://about.me/leongersing I honestly had no idea what I was getting in to when I sat down in to this session. I basically saw the picture of the speaker and knew that it would be a good session. I was completely wrong; it was the BEST SESSION of CodeStock 2012.  In fact it was so good, I texted another coworker attending the conference to get over and listen to Leon. Leon took on the concept of growth in the software development community. He specifically referred David Hansson in his ability to stick to his beliefs when the development community thought that he was crazy for creating Ruby on Rails. If you do not know this story Ruby on Rails is one of the fastest growing web languages today. In addition, he also touched on the flip side of this argument in that we must be open to others ideas and not discard them so quickly because we all come from differing perspectives and can add value to a project/team/community. This session left me with two very profound concepts/quotes: “In order to learn you must do it badly in front of a crowed and fail.” - @Rubybuddha I can look back on my career so far and say that he is correct; I think I have learned the most after failing, especially when I achieved this failure in front of other. “Experts must be able to fail.” - @Rubybuddha I think we can all learn from our own mistakes but we can also learn from others. When respected experts fail it is a great learning opportunity for the entire team as well as the person who failed. When expert admit mistakes and how they worked through them can be great learning tools for other developers so that they know how to avoid specific scenarios and if they do become stuck in the same issue they will know how to properly work their way out of them.

• Connecting to wireless networks from command line

  - by Balaji

  I need to write a shell script which connects to one of the two available wi-fi connections. One is a un secure connection and the other is secure connection. My question has 2 parts- 1.How to connect to the un-secure (un-encrypted and no password required) connection from command line (or by executing a shell script) when I'm connected to the secure connection? I followed the steps in http://www.ubuntugeek.com/how-to-troubleshoot-wireless-network-connection-in-ubuntu.html for in-secure connection. I put all the commands in a script and executed it (I made sure that interface name and essid are correct) - sudo dhclient -r wlan0 - sudo ifconfig wlan0 up - sudo iwconfig wlan0 essid "UAPublic" - sudo iwconfig wlan0 mode Managed - sudo dhclient wlan0 But nothing happens - I'm not disconnected from the current network and connected to the new one 2.When I want to connect to the secure wi-fi network, I understand from http://askubuntu.com/a/138476/70665 that I need to use wpa_supplicant. But I enter a lot of details in the interface when I connect via UI security : wpa and wpa2 enterprise Authentication : PEAP CA certificate : Equifax... PEAP version : automatic inner authentication : MSCHAPv2 username : password : How to use wpa_supplicant to mention all these details in the command line? The conf file network={ ssid="ssid_name" psk="password" } doesn't work for me.

• Flashback Database

  - by Sebastian Solbach (DBA Community)

  Flashback Database bezeichnet die Funktionalität der Oracle Datenbank, die Datenbank zeitlich auf einen bestimmten Punkt, respektive eine bestimmte System Change Number (SCN) zurücksetzen zu können - vergleichbar mit einem Rückspulknopf eines Kassettenrekorders oder der Rücksetztaste eines CD-Players. Mag dieses Vorgehen bei Produktivsystemen eher selten Einsatz finden, da beim Rücksetzten alle Daten nach dem zurückgesetzten Zeitpunkt verloren wären (es sei denn man würde dieser vorher exportieren), gibt es gerade für Test- oder Standby Systeme viele Einsatzmöglichkeiten: Rücksetzten des Systems bei fehlgeschlagenen Applikations-Upgrade Alternatives Point in Time Recovery (PITR) mit anschließendem Roll Forward (besonders geeignet bei Standby Systemen) Testdatenbank mit definiertem, reproduzierbaren Ausgangspunkt (z.B. für Real Application Testing) Datenbank Upgrade Test Einige bestehende Datenbank Funktionalitäten verwenden Flashback Database implizit: Snapshot Standby Reinstanziierung der Standby (z.B. bei Fast Start Failover) Obwohl diese Funktionalität gerade für Standby Systeme und Testsysteme bestens geeignet ist, gibt es eine gewisse Zurückhaltung Flashback Database einzusetzen. Eine Ursache ist oft die Angst vor zusätzlicher Last, die das Schreiben der Flashback Logs erzeugt, sowie der zusätzlich benötigte Plattenplatz. Dabei ist die Last im Normalfall relativ gering (ca. 5%) und auch der zusätzlich benötigte Platz für die Flashback Logs lässt sich relativ genau bestimmen. Ebenfalls wird häufig nicht beachtet, dass es auch ohne das explizite Einschalten der Flashback Logs möglich ist, einen garantieren Rücksetzpunkt (Guaranteed Restore Point kurz GRP) festzulegen, und die Datenbank dann auf diesen Restore Point zurückzusetzen. Das Setzen eines garantierten Rücksetzpunktes funktioniert in 11gR2 im laufenden Betrieb. Wie dies genau funktioniert, welche Unterschiede es zum generellen Einschalten von Flashback Logs gibt, wie man Flashback Database monitoren kann und was es sonst noch zu berücksichtigen gibt, damit beschäftigt sich dieser Tipp.

• c++ How to use angular velocity that derived from inertia and force(torque) in 3d

  - by user1217203

  I am relatively new to game development. May my terminology and description are not appropriate. Please excuse my poor phrasing and help me by giving advice on how to question better if this question seems less fitting. I really appreciate your efforts. Hi. I am having hard time interpreting the set of values I have. I have inertia and force(torque) in terms of x y z. FYI I used x and y coordinates as my ground, flat coordinates and z as my up/down. I am assuming that since f = ma, that angular acceleration must be a = f / m. So I divide my torque by inertia. Then I add those x y z values to my angular velocity variable's x y z. However these x y z values confuse me. Don't I need angle/sec or radian/sec sort of values in order to apply rotation? The x y z values I have seemed to not say anything about radians or angular movement. Question : If I have ( 1, 2, 3 ) or any ( x, y, z ) as my angular velocity, how do I actually apply it as angular movement? FYI Here I am pasting my code : float mass = 100; float devidedMass = 1.0/12 * mass; Vec3 innertia( devidedMass* (_box._size.z*_box._size.z + _box._size.x*_box._size.x), devidedMass* (_box._size.y*_box._size.y + _box._size.x*_box._size.x), devidedMass* (_box._size.y*_box._size.y + _box._size.z*_box._size.z )); box._angAccel += forceAng/innertia; box._angVelo += box._angAccel; box._angAccel.allZero(); source of my inertia calculation http://www.health.uottawa.ca/biomech/courses/apa4311/solids.pdf

• There's IP but can't reach gateway

  - by icky

  I have just installed ubuntu 12.04 on my new laptop, and brought it back to home, but I found the wireless network does not work. Strangely, it has the correct ip, but can't connect to the gateway. ifconfig gives ip 192.168.64.36, with broadcast 192.168.79.255 and mask 255.255.240.0, this are all correct, the gateway is at 192.168.64.1 cat /etc/resolv.conf nameserver 192.168.64.1 nameserver 127.0.0.1 which i think it's also right. but when I ping 192.168.64.1, all packages are lost.

• How to configure ubuntu ldap client to get password policies from server?

  - by Rafaeldv

  I have a ldap server on CentOS, 389-ds. I configured the client, ubuntu 12.04, to authenticate on that base and it works very well. But it don't gets the password policies from server. For example, if i set the policy to force user to change the password on first login, ubuntu ignores it and logs him in, always. How can i setup the client to get the policies?

• How do I modify these VPN connection settings for Xfce?

  - by Dave M G

  I have signed up for a VPN (Virtual Private Network) service, and I configured it for use on my computer that runs Gnome Classic with the following instructions: In Terminal, install openvpn packages with sudo apt-get install network-manager-openvpn. 1. Restart the network manager with sudo restart network-manager 2. Run sudo wget https://www.xxxxxxx.com/ovpnconfigure.zip 3. Extract the files from the zip with unzip ovpnconfigure.zip. 4. Move cert.crt to /etc/openvpn 5. Open the Network Manager on the menu bar. 6. Choose add and select the OpenVPN connection type, and click Create. 7. Enter Private Internet Access SSL for the Connection Name. 8. Enter xxxxxx.xxxxxxxx.com for the Gateway 9. Select Password and enter your login credentials. 10. Browse and select the CA Certificate we saved in Step 3. 11. Choose Advanced and enable LZO Compression. 12. Apply and exit. 13. Connect using the Network Manager. It worked, but now I want to set up access to the same VPN service on another machine that runs Mythbuntu, which uses Xfce as its desktop manager. So every point from 5 on doesn't apply. How can I modify the above instructions so that I can get my VPN service working with Xfce. As a further note, while I can access the Xfce desktop directly if I need to, it's more convenient for me to access it via the command line and SSH from on of my other computers. A command line process would be ideal. (I looked for this, and found instructions only for PPTP access, whereas I need OpenVPN.)

• GPU based procedual terrain borders?

  - by OnePie

  I'm working on a game that preferibly should feature a combination of designed and procedually generated terrain where the designer specifies in somewhat detailed terms what type of terrain a given area will have (grasslands, forest etc...) and then a precedual algorithm takes care of the rest. I'm not talking about minecraft style biomoes, but rather the game map for a strategy game. Each 'area' will not take up that much of the screen, and thus be more akin to a tile whose texture is procedually generated. While procedually generating terrain textures on the GPU are not that difficult, the hard part is making the borders between them look good. Currently, the 'tiles' are large enough to be visible (due to memory constraints mainly, we are talking planetary sized textures for a game taking place in space and on a continental ground view with seamless transitions between them) and creating good borders between them with an algorithm that is fast enough to be useful has proven difficult. Sampling the n-surrounding pixels and using the combiened result did not yield very good borders and was fairly slow on the GPU to boot (ca 12ms for me, that is without any lighning or shading and with very simple terrain texture shaders). So are there any practical known methods to solve this problem?

• Costs/profit of/when starting an indie company

  - by Jack

  In short, I want to start a game company. I do not have much coding experience (just basic understanding and ability to write basic programs), any graphics design experience, any audio mixing experience, or whatever else technical. However, I do have a lot of ideas, great analytical skills and a very logical approach to life. I do not have any friends who are even remotely technical (or creative in regards to games for that matter). So now that we've cleared that up, my question is this: how much, minimally, would it cost me to start such a company? I know that a game could be developed in under half a year, which means it would have to operate for half a year prior, and that's assuming that the people working on the first project do their jobs good, don't leave game breaking bugs, a bunch of minor bugs, etc.. So how much would it cost me, and what would be the likely profit in half a year? I'm looking at minimal costs here, as to do it, I would have to sell my current apartment and buy a new, smaller one, pay taxes, and likely move to US/CA/UK to be closer to technologically advanced people (and be able to speak the language of course). EDIT: I'm looking at a small project for starters, not a huge AAA title.

• What term is used to describe running frequent batch jobs to emulate near real time

  - by Steven Tolkin

  Suppose users of application A want to see the data updated by application B as frequently as possible. Unfortunately app A or app B cannot use message queues, and they cannot share a database. So app B writes a file, and a batch job periodically checks to see if the file is there, and if load loads it into app A. Is there a name for this concept? A very explicit and geeky description: "running very frequent batch jobs in a tight loop to emulate near real time". This concept is similar to "polling". However polling has the connotation of being very frequent, multiple times per second, whereas the most often you would run a batch job would be every few minutes. A related question -- what is the tightest loop that is reasonable. Is it 1 minute of 5 minutes or ...? Recall that the batch jobs are started by a batch job scheduler (e.g. Autosys, Control M, CA ESP, Spring Batch etc.) and so running a job too frequently would causes overhead and clutter.

• Should I use a config file or database for storing business rules?

  - by foiseworth

  I have recently been reading The Pragmatic Programmer which states that: Details mess up our pristine code—especially if they change frequently. Every time we have to go in and change the code to accommodate some change in business logic, or in the law, or in management's personal tastes of the day, we run the risk of breaking the system—of introducing a new bug. Hunt, Andrew; Thomas, David (1999-10-20). The Pragmatic Programmer: From Journeyman to Master (Kindle Locations 2651-2653). Pearson Education (USA). Kindle Edition. I am currently programming a web app that has some models that have properties that can only be from a set of values, e.g. (not actual example as the web app data confidential): light-type = sphere / cube / cylinder The light type can only be the above three values but according to TPP I should always code as if they could change and place their values in a config file. As there are several incidents of this throughout the app, my question is: Should I store possibly values like these in: a config file: 'light-types' = array(sphere, cube, cylinder), 'other-type' = value, 'etc = etc-value a single table in a database with one line for each config item a database with a table for each config item (e.g. table: light_types; columns: id, name) some other way? Many thanks for any assistance / expertise offered.

• Good links somehow being converted to ones with a PHP redirect (not a virus)

We might put www.oursite.org/work/ but when I view source it shows up as webmail.ourhosting.ca/hwebmail/services/go.php?url=https%3A%2F%2Fwww.oursite.org%2F%2work%2F This ends up at the webmail login page for our web host. But only some of the people who click the link get the login page; others go directly to the original page we intended. We don't want it to go to the webmail login page, nobody needs to log in to our web site. This occurs for links to pages on our site, but also to links to other sites that we put in emails or in posts. It seems to be browser independent as well as e-mail client independent as we variously have used Firefox and Chrome as well as MS Outlook and Thunderbird. I've tried to resolve the issue with our webhost but they keep telling me they don't support our browser, or our email client (i.e., they don't understand the issue). At the moment, our only option is to try another web host just to get rid of their login. Any ideas about what's going on?

• JVM Language Summit in July

  - by Tori Wieldt

  A reminder that the 2012 JVM Language Summit is happening July 30–August 1, 2012 in Santa Clara, CA. The JVM Language Summit is an open technical collaboration among language designers, compiler writers, tool builders, runtime engineers, and VM architects, sharing their experiences as creators of programming languages for the JVM, and of the JVM itself. Non-JVM developers are welcome to attend or speak on their runtime, VM, or language of choice. About 70 language and VM implementers attended last year—and over one third presented. What’s at the JVM Language Summit? Three days of technical presentations and conversations about programming languages and the JVM. Prepared talks by numerous visiting language experts, OpenJDK engineers, and other Java luminaries. Many opportunities to visit and network with your peers. Da Vinci Machine Project memorabilia. Dinner at a local restaurant, such as last year’s Faultline Brewing Company. A chance to help shape the future of programming languages on the JVM. Space is limited: This summit is organized around a single classroom-style room, to support direct communication between participants. To cover costs, there is a nominal conference fee of $100.

• Oracle Buys BigMachines - Adds Leading Configure, Price and Quote (CPQ) Cloud to the Oracle Cloud to Enable Smarter Selling

  - by Richard Lefebvre

  News Facts Oracle today announced that it has entered into an agreement to acquire BigMachines, a leading cloud-based Configure, Price and Quote (CPQ) solution provider. BigMachines’ CPQ Cloud accelerates the conversion of sales opportunities into revenue by automating the sales order process with guided selling, dynamic pricing, and an easy-to-use workflow approval process, accessible anywhere, on any device. Companies that use sales automation technology often rely on manual, cumbersome and disconnected processes to convert opportunities into orders. This creates errors, adds costs, delays revenue, and degrades the customer experience. BigMachines’ CPQ cloud extends sales automation to include the creation of an optimal quote, which enables sales personnel to easily configure and price complex products, select the best options, promotions and deal terms, and include up sell and renewals, all using automated workflows. In combination with Oracle’s enterprise-grade cloud solutions, including Marketing, Sales, Social, Commerce and Service Clouds, Oracle and BigMachines will create an end-to-end smarter selling cloud solution so sales personnel are more productive, customers are more satisfied, and companies grow revenue faster. More information on this announcement can be found at http://www.oracle.com/bigmachines Supporting Quotes “The fundamental goals of smarter selling are to provide sales teams with the information, access, and insights they need to maximize revenue opportunities and execute on all phases of the sales cycle,” said Thomas Kurian, Executive Vice President, Oracle Development. “By adding BigMachines’ CPQ Cloud to the Oracle Cloud, companies will be able to drive more revenue and increase customer satisfaction with a seamlessly integrated process across marketing and sales, pricing and quoting, and fulfillment and service.” “BigMachines has developed leading CPQ solutions that serve companies of all sizes across multiple industries,” said David Bonnette, BigMachines’ CEO. “Together with Oracle, we expect to provide a complete cloud solution to manage sales processes and deliver exceptional customer experiences.” Supporting Resources About Oracle and BigMachines General Presentation Customer and Partner Letter FAQ

• Is there a proven concept to website reverse certificate authentication?

  - by Tom

  We're looking at exposing some of our internal application data externally via a website. The actual details of the website aren't that interesting, it'll be built using ASP.NET/IIS etc, that might be relevant. With this, I'm essentially I'm looking for a mechanism to authenticate users viewing my website. This sounds trivial, a username/password is typically fine, but I want more. Now I've read plenty about SSL/x.509 to realise that the CA determines that we're alright, and that the user can trust us. But I want to trust the user, I want the user to be rejected if they don't have the correct credentials. I've seen a system for online banking whereby the bank issues a certificate which gets installed on the users' computer (it was actually smartcard based). If the website can't discover/utilise the key-pair then you are immediately rejected! This is brutal, but necessary. Is there a mechanism where I can do the following: Generate a certificate for a user Issue the certificate for them to install, it can be installed on 1 machine If their certificate is not accessible, they are denied all access A standard username/password scheme is then used after that SSL employed using their certificate once they're "in" This really must already exist, please point me in the right direction! Thanks for your help :)

• Web-Service: How much would you charge? [closed]

  - by jacksbox

  I´ve to make an offer to a client who wants me to develope a web-service for him. I have some trouble calculating the pricing - can you help me? Here is a rough outline of the project: It´s a portal on which various artists and entertainers can register and administrate there profile (texts, gallerie, some embedded videos, choose categories and radius of offer, etc). Other user can browse the artists by 3-4 level categories and countries/staats. If someone wants to hire a artists, he can put them in an "shopping-basket" and can mail everyone in his basket. The Artists can answer them with a form on the website (he doesn't get the email of the other person). Users should be able to comment/rate the artists. But if an artists wants this comments/ratings visible on his profile he must pay, and after that, the admin of the site must activate this comments/ratings. So, no more information given, what would you charge (ca.)? Edit: It´ll be developed with php/codeigniter. A .psd design is already there.

• Why is the camera not following the player? [on hold]

  - by Homer_Simpson

  I use the following code to create Parallax Scrolling: http://www.david-gouveia.com/portfolio/2d-camera-with-parallax-scrolling-in-xna/ Parallax Scrolling is working but I don't know how to focus the camera on the player. If the player moves, then the camera doesn't follow the player. The player leaves the screen when I'm moving it. I use the following code(as described in the tutorial), but it's not working: // Updates my camera to lock on the character _camera.LookAt(player.Playerposition); What can I do so that the player is always in the center of the screen/camera? My player class: public class Player { Texture2D Playertex; public Vector2 Playerposition = new Vector2(400, 240); private Game1 game1; public Player(Game1 game) { game1 = game; } public void Load(ContentManager content) { Playertex = content.Load<Texture2D>("8bitmario"); TouchPanel.EnabledGestures = GestureType.HorizontalDrag; } public void Update(GameTime gameTime) { while (TouchPanel.IsGestureAvailable) { GestureSample gs = TouchPanel.ReadGesture(); switch (gs.GestureType) { case GestureType.HorizontalDrag: Playerposition.X += 3f; break; } } } public void Render(SpriteBatch batch) { batch.Draw(Playertex, new Vector2(Playerposition.X - Playertex.Width / 2, Playerposition.Y - Playertex.Height / 2), Color.White); } } In Game1, I update the player and camera class: protected override void Update(GameTime gameTime) { // Updates my character's position player.Update(gameTime); // Updates my camera to lock on the character _camera.LookAt(player.Playerposition); base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); foreach (Layer layer in _layers) layer.Draw(spriteBatch); spriteBatch.Begin(SpriteSortMode.Deferred, null, null, null, null, null, _camera.GetViewMatrix(new Vector2(0.0f, 0.0f))); player.Render(spriteBatch); spriteBatch.End(); base.Draw(gameTime); }
