  • Bright Minds in Singapore: Oracle Graduate Hiring

    - by user769227
     Last week I was in Singapore and had the opportunity to take part in our graduate interviewing that we are currently undertaking as part of our ASEAN hiring. I always feel fortunate to get the chance to meet and talk with students in the APAC region and taking time to meet some of the students we interviewed in Singapore last week is no exception. The excitement and enthusiasm of many of the students that I spoke to last week really stands out but what really brought some of them to the forefront for me was their creative ways of thinking and the level of professionalism that I saw in the students. Some of the presentation and communication skills that I saw displayed would rival experienced IT Consultants in the industry.  We still have more interviews to follow up from last week, but I am confident that of the students we had the chance to meet last week some of them will go on to have bright and successful careers here at Oracle.  To all the students that came in and spent the day with us, I want to thank you for giving us your time and for sharing your thoughts and ideas with us. From a business perspective I think you all will go on and do great things and from a personal stand point I enjoyed many of the conversations I had and feel lucky to meet with you. Best of luck with the remainder of your interviews and I hope to see some of you in the halls on my next visit to Singapore.

  • The effects of Agile Programming can alter the five desirable properties of modeling tools and techniques

    The effects of Agile Programming can alter the five desirable properties of modeling tools and techniques as documented by Pfleeger. The agile methodology does promote human understanding and communication through the use of short iterative software development life cycles which forces stakeholders to review the project and adjust the project for any requirement changes.  Due to the consistent evaluations of a project and requirements, process are continually being refined, upgraded, and compared against other alternatives to ensure the best design delivered to the client. Due to the short repetitive development cycles, increased time is devoted to process management due to the fact that requirements and designs could be constantly changing. This requires additional forecasting, monitoring, and planning for each iteration. Because things can change so rapidly, automated guidance in performing process must be updated for each iteration because the environment and the available reusable process could change. In addition, the original guidance and suggestions for the project also need to be updated to account for these changes as well.   In essence the automation of process execution is supported by the agile methodology because during every iteration all processes must be tested, evaluated to ensure process integrity and compliance with the customer’s requirements. I do not think the agile approach diminishes modeling, in fact I think it increases the modeling because before the start of every development cycle, modeling must be checked for accuracy based on the changed requirements. So in essence the reduced time spent initially designing the models is in fact gained as the project completes every iteration of the project.

  • What You Said: Cutting the Cable Cord

    - by Jason Fitzpatrick
    Earlier this week we asked you if you’d cut the cable and switched to alternate media sources to get your movie and TV fix. You responded and we’re back with a What You Said roundup. One of the recurrent themes in reader comments and one, we must admit, we didn’t expect to see with such prevalence, was the number of people who had ditched cable for over-the-air HD broadcasts. Fantasm writes: I have a triple HD antenna array, mounted on an old tv tower, each antenna facing out from a different side of the triangular tower. On tope of the tower are two 20+ year old antennas… I’m 60 miles from toronto and get 35 channels, most in brilliant HD… Anything else, comes from the Internet… Never want cable or sat again… Grant uses a combination of streaming services and, like Fantasm, manages to pull in HD content with a nice antenna setup: We use Netflix, Hulu Plus, Amazon Prime, Crackle, and others on a Roku as well as OTA on a Tivo Premier. The Tivo is simply the best DVR interface I have ever used. The Tivo Netflix application, though, is terrible, and it does not support Amazon Prime. Having both boxes makes it easy to use all of the services. 6 Ways Windows 8 Is More Secure Than Windows 7 HTG Explains: Why It’s Good That Your Computer’s RAM Is Full 10 Awesome Improvements For Desktop Users in Windows 8

  • Nginx request forking

    - by Adam
    Hi, I'm wondering if nginx can "fork" a request. Let's imagine config: upstream backend { server localhost:8080; ... more servers here } server { location /myloc { FORK-REQUEST http://my-other-url:3135/something proxy_pass http://backend; } } I would like nginx to send a copy of request to the url specified by FORK-REQUEST and after that to load balance it with backend servers and return the response to the client. As I don't need the response from FORK-REQUEST it would be best if this request was async so normal prcessing doesn't have to wait. Is a scenario like this possible?

  • Is Play Framework good for doing some logic parallely?

    - by pmichna
    I'm going to build a web application that's going to host urban games. A user visits my website, clicks "Start game" and starts receiving some SMS messages when gets to some location and has to answer them to get points. My question: is Play suitable for this kind of application? From what I've read I know for sure it's ok for traditional web applications: user interface for same data storage and manipulation. But what if after clicking the "start button" some logic has to go on its own course? How would I handle parallely checking geolocation of the players (I have API for that)? I guess in some threads that would ping them every ~5 sec. and do some processing but is it possible to just "disconnect" them from the main user interface? So to sum up: I want an application written in Play that starts a separate thread for a game after clicking "start game" and other users are able to view their data (statisctics etc.), while the threads work their way with the game logic. I found something like jobs but they are documented for version 1.2 (current one is 2.2). Sorry for my somewhat fuzzy explenation, I tried to do my best.

  • SELinux adding new allowed samba type to access httpd_sys_content_t?

    - by Josh
    allow samba_share_t httpd_sys_content_t {read execute getattr setattr write}; allow smbd_t httpd_sys_content_t {read execute getattr setattr write}; I am taking a stab in the dark with resources I've looked at, at various places that the above policies are what I want. I basically want to allow Samba to write to my web docs without giving it free access to the operating system. I read a post by a NSA rep saying the best way was defining a new type and allowing both samba and httpd access. Setting the content to public content (public_content_rw_t) does not work without making use of some unrestrictive booleans. To state this in short, how do I allow samba to access a new type?

  • Recovering text files in terminal using grep on Mac OS X Snow Leopard

    - by littlejim84
    I foolishly removed some source code from my Mac OS X Snow Leopard machine with rm -rf when doing something with buildout. I want to try and recover these files again. I haven't touched the system since to try and seek an answer. I found this article and it seems like the grep method is the way to go, but when running it on my machine I'm getting 'Resource busy' when trying to run it on the disk. I'm using this command: sudo grep -a -B1000 -A1000 'video_output' /dev/disk0s2 > file.txt Where 'dev/disk0s2' is what came up when I ran df. I get this when running: grep: /dev/disk0s2: Resource busy I'm not an expert with this stuff, I'm trying my best. Please can anyone help me further? I'm on the verge of losing two days of source code work! Thank you

  • How can I lock my Mac when I walk away?

    - by schnapple
    This has got to be an easy, trivial question but as a new Mac user, how can I lock my Mac when I walk away? On Windows this is dead simple - Win+L. Or hit Ctrl-Alt-Del and select "Lock this Computer" The best thing I've found for the Mac is to rig the screensaver to require password on wake, set a hot corner to fire off the screen saver, and do that as I leave. Which feels really "Windows 3.1" to me. Is there a Win+L-style method to quickly lock my Mac when I walk away?

  • How to securely store and update backup on remote server via ssh/rsync

    - by Sergey P. aka azure
    I have about 200 Gb of pictures (let's say about 1 mb/file, 200k files) on my desktop. I have access (including root access) to remote linux server. And I want to have updateable backup of my pictures on remote server. rsync seems to be the right tool for such kind of job. But other people also have access (including root access) to this server and I want to keep my pictures private. So the question is: what is the best way to keep private files on remote "shared" linux server securely?

  • Hyper-V networking....still not sure which way to go??

    - by CZhale
    We have our Hyper-V server up and running (Windows 2008 ENT SP2) and started to create some of our VMs. The server has 4 total nics. 2 onboard Broadcom 1gb nic cards and a pci dual port Intel Pro cards 1gb. Right now, I have setup 1 broadcom nic to be the hyper-v host nic, and setup the other broadcom nic for the VMs. We are not using the Intel Nics....should we be thinking about teaming?Link Aggregation?? I just want to achieve the best possible setup for the network, but have read many things for and against teaming the nics?? Thoughts?

  • aligning truecrypt partition on 1.5TB 4kB sector drive

    - by pQd
    hi, aligning partitions to start at real physical sector of ssds / stripped raids / 4kB drives is a 'good thing to do'. but i've run into a problems when trying to do it for a truecrypt partition that will contain ext3 on it. or so it seems. when drive is question is partitioned properly and formatted with ext3 i get very reasonable write speeds around 70-80MB/s, but when i put truecrypt and ext3 on the top of it write performance becomes very unstable and goes between 1-25MB/s with very high io-wait. on the same server i dont have any performance issues with ext3 on the top of truecrypt on regular 512B-sector 500GB sata disks. so my best guess is that iowaits are caused by misalignment but i cannot really find reliable information on how to calculate optimal partition beginning. i've tried to start it at 128 logical sector, i've also tried 8132 sector as suggested here but both gave me very bad and unstable performance. do you have any experience with similar setup? thanks!

  • Mouse wheel speed, a permanent solution?

    - by Logan
    I would like to address an issue that has been around for a while now. The wireless mouse's wheel speed is abnormally fast on Ubuntu (as well as Mac Osx, as I have read) and the way to fix this temporarily is to unplug and plug the wireless adapter. A solution for this have been asked for in various forum topics on Ubuntu forums and also askubuntu. However the best solution for this is to re-plug the wireless adapter for the mouse. This fixes the mouse wheel speed until the next reboot. My question is, what can be done to make this permanent? Can a shell script be written, or firstly what can be causing this? If you could give me some ideas on why this problem is occurring I would happily write a shell script for it... (I am thinking if this is fixed by a simple re-plug of the adapter, maybe a shell script to disable device and re-enable it or something like that... could do the trick) I appreciate any discussions and ideas on the subjects. Here are some already discussed topics on the same subject that I've researched: Mouse wheel jumpy on scrolling Mouse wheel scrolling too fast There's a lot more than that on the net, all of them ends with re-plug solution.

  • Can't get sprite to rotate correctly?

    - by rphello101
    I'm attempting to play with graphics using Java/Slick 2d. I'm trying to get my sprite to rotate to wherever the mouse is on the screen and then move accordingly. I figured the best way to do this was to keep track of the angle the sprite is at since I have to multiply the cosine/sine of the angle by the move speed in order to get the sprite to go "forwards" even if it is, say, facing 45 degrees in quadrant 3. However, before I even worry about that, I'm having trouble even getting my sprite to rotate in the first place. Preliminary console tests showed that this code worked, but when applied to the sprite, it just kind twitches. Anyone know what's wrong? int mX = Mouse.getX(); int mY = HEIGHT - Mouse.getY(); int pX = sprite.x; int pY = sprite.y; int tempY, tempX; double mAng, pAng = sprite.angle; double angRotate=0; if(mX!=pX){ tempY=pY-mY; tempX=mX-pX; mAng = Math.toDegrees(Math.atan2(Math.abs((tempY)),Math.abs((tempX)))); if(mAng==0 && mX<=pX) mAng=180; } else{ if(mY>pY) mAng=270; else mAng=90; } //Calculations if(mX<pX&&mY<pY){ //If in Q2 mAng = 180-mAng; } if(mX<pX&&mY>pY){ //If in Q3 mAng = 180+mAng; } if(mX>pX&&mY>pY){ //If in Q4 mAng = 360-mAng; } angRotate = mAng-pAng; sprite.angle = mAng; sprite.image.setRotation((float)angRotate);

  • Does the Wacom Bamboo Pen Tablet's Pen have an Eraser?

    - by Vervious
    I'm thinking about getting one of the cheaper Wacom tablets to start doing some "hobby"-ish digital art. Right now I think the Bamboo tablets are the best choice, especially the Pen only one, but after reading reviews it seems like the pen with the Bamboo pen doesn't have an eraser. Can anyone verify this? If it doesn't include a digital eraser I would consider this an enormous downside. Does the Bamboo Pen & Touch have a pen with an eraser? If it does, I would think about it but honestly I don't want the "touch" part considering how terrible it seems to be compared to a normal trackpad. And finally, are there any new Bamboos or something related coming out in the future? I'd like a pen-only tablet (with an eraser) that's cheap and portable and nothing seems to satisfy yet. EDIT: The main question (the eraser one) is talking about the Bamboo Pen CTL460 http://www.wacom.com/bamboo/bamboo_pen.php

  • K-12 and Cloud considerations

    - by user736511
    Much like every other Public Sector organization, school districts in the US and Canada are under tremendous pressure to deliver consistent and modern services while operating with reduced budgets, IT personnel shortages, and staff attrition.  Electronic/remote learning and the need for immediate access to resources such as grades, calendars, curricula etc. are straining IT environments that were already burdened with meeting privacy requirements imposed by both regulators and parents/students.  One area viewed as a solution to at least some of the challenges is the use of "Cloud" in education.  Although the concept of "Cloud" is nothing new in education with many providers supplying educational material over the web, school districts defer previously-in-house-hosted services to established commercial vendors to accommodate document sharing, app hosting, and even e-mail.  Doing so, however, does not reduce an important risk, that of privacy.  As always, Cloud implementations are viewed in a skeptical manner because of the perceived reduction in sensitive data management and protection thereof, although with a careful approach and the right tooling, the benefits realized by Clouds can expand to security and privacy.   Oracle's comprehensive approach to data privacy and identity management ensures that the necessary tools are available to support regulations, operational efficiencies and strong security regardless of where the sensitive data is stored - on premise or a Cloud.  Common management tools, role-based access controls, access policy management and engineered systems provided by Oracle can be the foundational pieces on which school districts can build their Cloud implementations without having to worry about security itself. Their biggest challenge, and it is a positive one, is how to best take advantage of Oracle's DB Security and IDM functionality to reduce operational costs while enabling modern applications and data delivery to those who needs access to it.

  • App to make a video from photos?

    - by chtfn
    I was wondering what could be a good app (with a GUI ;) ) for making a video from a bunch of photos or images, to create a time-lapse video, or a stop-motion animation, or even a video like this one. The idea is to set a really small time between each photo, but also to be able to change this time every so often, or add some effects, to make the succession smoother in particular. What would be perfect is a function that allows automatic cropping of the photos as well as exposure adjustment so they all have the same background and so the time-lapse video looks smoother. I know about the slide show app "Imagination" but the interval can not go under one second. Cheers! Edit: here is my progress, also thanks to the first answer: I tried Luciole, it is really simple and promessing, but pretty buggy, and I only could export an average video in .dv format (mpg2 and avi don't work). Apparently, it has difficulties when changing the fps. I also tried StopMotion: also pretty buggy, I had to go into preferences and modify the encoding commands to get a result, but it's the best result I got so far. But none of those has effects to make transitions smoother... I tried several diaporama apps: Imagination doesn't handle more than 1 image per second; PhotoFilmStrip (repo version and latest version from website): same problem even though you can go down to 0.1 second per image, it still behaves wierdly (going back to 1 second automatically); Videoporama: doesn't start at all on 12.04. Any other idea, folks?

  • Choosing Technology To Include In Software Design

    How many of us have been forced to select one technology over another when designing a new system? What factors do we and should we consider? How can we ensure the correct business decision is made? When faced with this type of decision it is important to gather as much information possible regarding each technology being considered as well as the project itself. Additionally, I tend to delay my decision about the technology until it is ultimately necessary to be made. The reason why I tend to delay such an important design decision is due to the fact that as the project progresses requirements and other factors can alter a decision for selecting the best technology for a project. Important factors to consider when making technology decisions: Time to Implement and Maintain Total Cost of Technology (including Implementation and maintenance) Adaptability of Technology Implementation Team’s Skill Sets Complexity of Technology (including Implementation and maintenance) orecasted Return On Investment (ROI) Forecasted Profit on Investment (POI) Of the factors to consider the ROI and POI weigh the heaviest because the take in to consideration the other factors when calculating the profitability and return on investments.For a real world example let us consider developing a web based lead management system for a new company. This system can either be hosted on Microsoft Windows based web server or on a Linux based web server. Important Factors for this Example Implementation Team’s Skill Sets Member 1  Skill Set: Classic ASP, ASP.Net, and MS SQL Server Experience: 10 years Member 2  Skill Set: PHP, MySQL, Photoshop and MS SQL Server Experience: 3 years Member 3  Skill Set: C++, VB6, ASP.Net, and MS SQL Server Experience: 12 years Total Cost of Technology (including Implementation and maintenance) Linux Initial Year: $5,000 (Random Value) Additional Years: $3,000 (Random Value) Windows Initial Year: $10,000 (Random Value) Additional Years: $3,000 (Random Value) Complexity of Technology Linux Large Learning Curve with user driven documentation Estimated learning cost: $30,000 Windows Minimal based on Teams skills with Microsoft based documentation Estimated learning cost: $5,000 ROI Linux Total Cost Initial Total Cost: $35,000 Additional Cost $3,000 per year Windows Total Cost Initial Total Cost: $15,000 Additional Cost $3,000 per year Based on the hypothetical numbers it would make more sense to select windows based web server because the initial investment of the technology is much lower initially compared to the Linux based web server.

  • How do MaxSpareServers work in Apache?

    - by John Hunt
    I've scoured the web but I can't find out what MaxSpareServers are in Apache MPM prefork.. The MaxSpareServers directive sets the desired maximum number of idle child server processes. An idle process is one which is not handling a request. If there are more than MaxSpareServers idle, then the parent process will kill off the excess processes. Great, but what causes a spareserver to be created? More importantly, when does a spare server go away? I understand that minspareservers are created gradually after the server is started.. How do maxspareservers relate to maxclients? Basically I'm at a bit of a loss on how best to configure Apache.. there's a lot of documentation out there but it isn't that clear. Thanks, John.

  • Comparing zip/compression utilities

    - by Grant Palin
    I've used WinZip, WinRar, and 7zip for packaging and compression. I know the first two are payware, and the last is open source. Despite that, they all seem to serve the same overall purpose. Are there any other distinguishing characteristics that make any of the options stand out? I'm not really looking for a "best" package, but would like to know of noteworthy differences between the common tools. For what it's worth, I do seem to like WinRar. Not sure why, but there it is. If it matters, I'm using Windows 7.

  • Make GRUB automatically boot Ubuntu

    - by Matt Robertson
    I am running a dual-boot with Ubuntu (10.10) and Windows 7. Recently I edited my /boot/grub/grub.cfg file to only show one version of Ubuntu (as opposed to several kernel versions) and Windows, simply by commenting out all other menu entries. My question is if I can edit GRUB to just boot a specific entry automatically. I tried removing all other menu entries, but GRUB still showed the menu with only one entry. I've also considered just setting the timeout to either 0 or 1 second, as this would basically achieve the same thing. What is the best way to do this?

  • Glimpse: Open Source Web Development

    - by Elizabeth Ayer
    We’re delighted to announce that Red Gate will be backing Glimpse! For those of you who aren’t familiar with the project, Glimpse is an open source tool which does for the server what Firebug does for the client. It’s been in beta for the last year, and we’re very excited to give Glimpse the support and dedicated effort needed to take it to a v1 and beyond. Glimpse’s founders (Nik Molnar and Anthony van der Hoorn) have joined Red Gate, and they’re just as excited as we are about the opportunities that active development of Glimpse will bring. They will continue to write code, support the community and drive the project forward (as they’ve done since its inception). With full-time attention on growing Glimpse and its community, users and developers can expect the project to accelerate, with frequent releases of new functionality. Red Gate is excited about its first major involvement with open source. You may well be wondering, though, why Red Gate is doing this. Glimpse dovetails beautifully with Red Gate’s .NET tools, which makes Glimpse an ideal framework for plugging in advanced, paid-for functionality (like performance analysis) the way web developers want to see it. As a means to this end, we will contribute to the Glimpse open source project in order to broaden its adoption and delight web developers. Since bringing in .NET Reflector in 2008, we’ve learnt sharp lessons from the community about the right and wrong ways to engage with developers, not to mention the enduring value of free. Glimpse further shows what the .NET community can achieve through open source collaboration, and we’re looking forward to working with the Glimpse community to make something enduring and awesome. Nik and Anthony, themselves passionate advocates of community-driven software, will continue to control the Glimpse project, steering it to best meet the needs of its users and contributors. If you have any questions or queries about Glimpse, or Red Gate’s involvement in the project, please tweet with the #glimpse hashtag, contact us at Red Gate on [email protected], or post to the Glimpse Development Forum on Google Groups.

  • Using Quickly for text-heavy app

    - by Kevin
    I am trying to create a small app that displays documentation. When it is run, the application window will display a main menu with buttons labeled 'Document 1', 'Document 2', etc. If a user clicks on one of those buttons, the text from the corresponding document will be displayed in the window. Very basic. The text documents range in length from 1000 to 5000 words, and they need basic formatting (bold, italic, maybe one or two font choices). My question is this: what is the best way to store and display long blocks of formatted text, using Quickly? There seems to be a few options: (1) I could load the text blocks into long python strings, (2) I could load the text from text files, or (3) I could somehow copy and paste the formatted text into Glade. In the first two options, I'm not sure how I would format the text (add italic and bold, for instance) once it was loaded. I have experience with PHP/MySQL/HTML/CSS/Javascript, but I'm new to Python. Any help would be appreciated.
