  • TechEd North America 2012–Day 3 #msTechEd #teched

    - by Marco Russo (SQLBI)
    Yesterday I spent the longest day at this TechEd: we talked with many people at Community Night until 9pm and I have to say that just a few months after Analysis Services 2012 has been released, there are many people already using it. And the adoption of PowerPivot is starting to be quite large. Many new ideas and challenging coming from several different real world scenarios. I was tired but really happy. Alberto presented his Many-to-Many Relationships in BISM Tabular session that was in the same time slot of the BI Power Hour. For this reason, very few people attended Alberto’s session so I think many will watch the recorded session (it should be available within a few days). So what about today? I’ll spend some time at Technical Learning Center area (full schedule here) but the most important event today will be the Querying multi-billion rows with many to many relationships in SSAS Tabular (xVelocity) at the Private Cloud, Public Cloud and Data Platform Theater in the Technical Learning Center area (next to the SQL Server 2012 zone).  Why you should attend? Mainly because you will see live demo over 4 billion rows table with many-to-many relationships involved in complex queries. But for those of you that think this is not enough to attend a 15 minute funny session, well, we’ll give away some 8GB USB Memory Keys to those of you that will guess exact response time of queries before execution. Convinced? Join us at 11:15am and don’t be late, the session will finish at 11:30am! After that, we’ll run a book signing session at the Bookstore at 12:30pm and I will be in the Technical Learning Center area at 3:00pm until 5:00pm. See you there!

  • How to refactor a myriad of similar classes

    - by TobiMcNamobi
    I'm faced with similar classes A1, A2, ..., A100. Believe it or not but yeah, there are roughly hundred classes that almost look the same. None of these classes are unit tested (of course ;-) ). Each of theses classes is about 50 lines of code which is not too much by itself. Still this is way too much duplicated code. I consider the following options: Writing tests for A1, ..., A100. Then refactor by creating an abstract base class AA. Pro: I'm (near to totally) safe by the tests that nothing goes wrong. Con: Much effort. Duplication of test code. Writing tests for A1, A2. Abstracting the duplicated test code and using the abstraction to create the rest of the tests. Then create AA as in 1. Pro: Less effort than in 1 but maintaining a similar degree of safety. Con: I find generalized test code weird; it often seems ... incoherent (is this the right word?). Normally I prefer specialized test code for specialized classes. But that requires a good design which is my goal of this whole refactoring. Writing AA first, testing it with mock classes. Then inheriting A1, ..., A100 successively. Pro: Fastest way to eliminate duplicates. Con: Most Ax classes look very much the same. But if not, there is the danger of changing the code by inheriting from AA. Other options ... At first I went for 3. because the Ax classes are really very similar to each other. But now I'm a bit unsure if this is the right way (from a unit testing enthusiast's perspective).

  • When does a programmer know when a new job is not right?

    - by Mysterion
    I believe that the interview process is a selling of both parties - what can the employee offer the employer and vice versa. Assuming an individual has been careful in selecting their new employer (via thorough questioning in the interview process), however when they arrive at the job they find the employer has not been honest about certain aspects of the job. Examples of this dishonesty could include: The employee making it clear that technical excellence is an important factor, which is promised by the employer, but is not fully delivered or a good technical structure does not exist. The employee states they want to work on well architected and short (lets say less than 1 yr) long projects, yet when they start they find they are placed on a poorly architected older project. The employee being told of a pair programming environment to get him up to speed on the project, but being left to his own devices/questioning on arrival. The employee is promised a culture that encourages innovation and technical excellence but finds that this is not the case (eg. using technology for knowledge retention is laughed at). I know that a lot of famous developers feel that you make the place you work at. Is it realistic for a new employee with limited experience in the industry (say less than 5 years) to be able to join the company and change attitudes or even challenge the employer on the perceived dishonesty? Should they stay in this job or cut their losses?

  • I just started a job with Scrum and something seems to be missing. I am new to Scrum

    - by punkouter
    The code is a complete mess of a combination of classic ASP/ASP.NET. The scrum consist of us patching up the big mess or making additions to it. We are all too busy doing that to start a rewrite so I am wondering.. Where is the part in Scrum where the developers can have the power to say that enough is enough and demand that they are given time to start the big rewrite? We seem in an endless loop of just patching old code with 'Stories'. So things are being run by the non-technical people who seem to have no desire to push for a rewrite because they don't understand how bad the codebase has gotten.. So who is in charge of making this big rewrite change happen? The developers? The Scrum Master? The current strategy is just to find time and do it ourselves without the higher-ups involved since they are mostly to blame for the current mess we are in.. <- insert rant about non-technical people telling technical people what to do here ->.

  • What is the breakdown of jobs in game development?

    - by Destry Ullrich
    There's a project I'm trying to start for Indie Game Development; specifically, it's going to be a social networking website that lets developers meet through (It's a secret). One of the key components is showing what skills members have. Question: I need to know what MAJOR game development roles are not represented in the following list, keeping in mind that many specialist roles are being condensed into more broad, generalist roles: Art Animator (Characters, creatures, props, etc.) Concept Artist (2D scenes, environments, props, silhouettes, etc.) Technical Artist (UI artists, typefaces, graphic designers, etc.) 3D Artist (Modeling, rigging, texture, lighting, etc.) Audio Composer (Scores, music, etc.) Sound Engineer (SFX, mood setting, audio implementation, etc.) Voice (Dialog, acting, etc.) Design Creative Director (Initial direction, team management, communications, etc.) Gameplay Designer (Systems, mechanics, control mapping, etc.) World Designer (Level design, aesthetics, game progression, events, etc.) Writer (Story, mythos, dialog, flavor text, etc.) Programming Engine Programming (Engine creation, scripting, physics, etc.) Graphics Engineer (Sprites, lighting, GUI, etc.) Network Engineer (LAN, multiplayer, server support, etc.) Technical Director (I don't know what a technical director would even do.) Post Script: I have an art background, so i'm not familiar with what the others behind game creation actually do. What's missing from this list, and if you feel some things should be changed around how so?

  • ArchBeat Link-o-Rama for November 6, 2012

    - by Bob Rhubart
    OAM/OVD JVM Tuning | @FusionSecExpert Vinay from the Oracle Fusion Middleware Architecture Group (the infamous A-Team) shares a process for analyzing and improving performance in Oracle Virtual Directory and Oracle Access Manager. Architects Matter: Making sense of the people who make sense of enterprise IT Why do architects matter? Oracle Enterprise Architect Eric Stephens suggests that you ask yourself that question the next time you take the elevator to the Oracle offices on the 45th floor of the Willis Tower in Chicago, Illinois (or any other skyscraper, for that matter). If you had to take the stairs to get to those offices, who would you blame? "You get the picture," he says. "Architecture is essential for any necessarily complex structure, be it a building or an enterprise." (Read the article...) SOA Galore: New Books for Technical Eyes Only Shake up up your technical skills with this trio of new technical books from community members covering SOA and BPM. Thought for the Day "It goes against the grain of modern education to teach students to program.

  • Layers - Logical seperation vs physical

    - by P.Brian.Mackey
    Some programmers recommend logical seperation of layers over physical. For example, given a DL, this means we create a DL namespace not a DL assembly. Benefits include: faster compilation time simpler deployment Faster startup time for your program Less assemblies to reference Im on a small team of 5 devs. We have over 50 assemblies to maintain. IMO this ratio is far from ideal. I prefer an extreme programming approach. Where if 100 assemblies are easier to maintain than 10,000...then 1 assembly must be easier than 100. Given technical limits, we should strive for < 5 assemblies. New assemblies are created out of technical need not layer requirements. Developers are worried for a few reasons. A. People like to work in their own environment so they dont step on eachothers toes. B. Microsoft tends to create new assemblies. E.G. Asp.net has its own DLL, so does winforms. Etc. C. Devs view this drive for a common assembly as a threat. Some team members Have a tendency to change the common layer without regard for how it will impact dependencies. My personal view: I view A. as silos, aka cowboy programming and suggest we implement branching to create isolation. C. First, that is a human problem and we shouldnt create technical work arounds for human behavior. Second, my goal is not to put everything in common. Rather, I want partitions to be made in namespaces not assemblies. Having a shared assembly doesnt make everything common. I want the community to chime in and tell me if Ive gone off my rocker. Is a drive for a single assembly or my viewpoint illogical or otherwise a bad idea?

  • English major new to programming. What language should I learn first? [closed]

    - by PJKaka
    After working extensively an internet startup in a marketing positions, I've decided to wade into the entrepreneurship pool with a startup of my own. The only problem: I don't have any particular technical skills to speak of. Although I can find a technical co-founder, I'd rather not be the stereotypical 'business guy' drumming his fingers on the desk and asking 'how much longer?' as my technical co-founder codes away. I would like to understand code and what's happening in the backend, even if I don't end up being anything more than a 'passable' programmer. With this in mind, which language should I try to learn first? For the record, I'm quite proficient with HTML, CSS, and a bit of JavaScript. I have some familiarity with PHP because I've toyed around with WordPress a lot, but my knowledge is limited at best. My math skills are quite strong. I took some advanced calculus courses in college since I've always enjoyed the subject. While my goals are to learn web development, I wouldn't mind learning some hardcore object oriented programming skills in C or Java as well.

  • How do I make my page respect h1 css addition? [migrated]

    - by Adobe
    I add h1 { margin-top:100px; } to the end of the css, but the page doesn't change. But if I add to the html of some h1: <h1 style="margin-top:100px;"><a class="toc-backref" href="#id4">KHotKeys</a><a class="headerlink" href="#khotkeys" title="Permalink to this headline">¶</a></h1> Then it does.

  • ImageMagick on Mac OSX Snow Leopard. Is there any way to get it to work?

    It seems that I have more trouble getting standard Unix things to run on Snow Leopard than any other platform--including Windows cygwin For the past couple of days, I've been trying to get ImageMagick to run on Snow Leopard. The most obvious way, Mac Ports, fails: tppllc-Mac-Pro:ImageMagick-sl swirsky$ sudo port install imagemagick ---> Computing dependencies for p5-locale-gettext ---> Configuring p5-locale-gettext Error: Target org.macports.configure returned: configure failure: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_perl_p5-locale-gettext/work/gettext-1.05" && /opt/local/bin/perl Makefile.PL INSTALLDIRS=vendor " returned error 2 Command output: checking for gettext... no checking for gettext in -I/opt/local/include -arch i386 -L/opt/local/lib -lintl...gettext function not found.

So now I'm two steps away from ImageMagick, trying to get a newer libiconv on my machine. I downloaded the latest libiconv, compiled and built it. I put the resulting library in /opt/local/lib, and I still get the same error message: tppllc-Mac-Pro:.libs swirsky$ sudo mv libiconv.2.dylib /opt/local/lib/libiconv.2.dylib tppllc-Mac-Pro:.libs swirsky$ convert dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib Referenced from: /opt/local/lib/libfontconfig.1.dylib Reason: Incompatible library version: libfontconfig.1.dylib requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0 Trace/BPT trap So here's my question: Is it possible to get ImageMagick to run on OSX Snow Leopard? Are there any binary distributions that have static libraries baked in so I don't have to worry about these issue/

  • When to delete newly deprecated code?

    - by John
    I spent a month writing an elaborate payment system that handles both credit card payments and electronic fund transfers. My work was used on production server for about a month. I was told recently by the client that he no longer wants to use the electronic fund transfer feature. Because the way I had to interface and communicate with the credit card gateway is drastically different from the electronic fund transfer api (eg. the cc company gives transaction responses immediately after an http request, while the eft company gives transaction responses 5 business days after an http request), I spent a lot of time writing my own API to abstract common function calls like function payment(amount, pay_method,pay_freq) function updateRecurringSchedule(user_id,new_schedule) etc.. Now that the client wants to abandon the EFT feature, all my work for this abstracted payments API is obsolete. I'm deliberating over whether I should scrap my work. Here's my pro vs. con for scrapping it now: PRO 1: Eliminate code bloat PRO 2: New developers do not need to learn MY API. They only need to read the CC company's API PRO 3: Because the EFT company did not handle recurring payment schedules, refunds, and validation, I wrote my own application to do it. Although the CC company's API permitted this functionality, I opted to use mine instead so that I could streamline my code. now that EFT is out of the picture, I can delete all this confusing code and just rely on the CC company's sytsem to manage recurring billing, payment schedules, refunds, validations etc... CON 1: Although I can just delete the EFT code, it still takes time to remove the entire framework consolidates different payment systems. CON 2: with regards to PRO 3, it takes time to build functionality that integrates the payment system more closely with the CC company. CON 3: I feel insecure deleting all this work. I don't think I'll ever use it again. But, for some inexplicable reason, I just don't feel comfortable deleting this work "right now". So my question is, should I delete one month's worth recent development? If yes, should I do it immediately or wait X amount of time before doing so?

  • unexplainable packet drops with 5 ethernet NICs and low traffic on Ubuntu

    - by jon
    I'm stuck on problem where my machine started to drops packets with no sign of ANY system load or high interrupt usage after an upgrade to Ubuntu 12.04. My server is a network monitoring sensor, running Ubuntu LTS 12.04, it passively collects packets from 5 interfaces doing network intrusion type stuff. Before the upgrade I managed to collect 200+GB of packets a day while writing them to disk with around 0% packet loss depending on the day with the help of CPU affinity and NIC IRQ to CPU bindings. Now I lose a great deal of packets with none of my applications running and at very low PPS rate which a modern workstation NIC would have no trouble with. Specs: x64 Xeon 4 cores 3.2 Ghz 16 GB RAM NICs: 5 Intel Pro NICs using the e1000 driver (NAPI). [1] eth0 and eth1 are integrated NICs (in the motherboard) There are 2 other PCI-X network cards, each with 2 Ethernet ports. 3 of the interfaces are running at Gigabit Ethernet, the others are not because they're attached to hubs. Specs: [2] http://support.dell.com/support/edocs/systems/pe2850/en/ug/t1390aa.htm uptime 17:36:00 up 1:43, 2 users, load average: 0.00, 0.01, 0.05 # uname -a Linux nms 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I also have the CPU governor set to performance mode and irqbalance off. The problem still occurs with them on. # lspci -t -vv -[0000:00]-+-00.0 Intel Corporation E7520 Memory Controller Hub +-02.0-[01-03]--+-00.0-[02]----0e.0 Dell PowerEdge Expandable RAID controller 4 | \-00.2-[03]-- +-04.0-[04]-- +-05.0-[05-07]--+-00.0-[06]----07.0 Intel Corporation 82541GI Gigabit Ethernet Controller | \-00.2-[07]----08.0 Intel Corporation 82541GI Gigabit Ethernet Controller +-06.0-[08-0a]--+-00.0-[09]--+-04.0 Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) | | \-04.1 Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) | \-00.2-[0a]--+-02.0 Digium, Inc.

On the old system, if it couldn't keep up this is where the drops would be. I drop packets on multiple interfaces just about every second, usually in small increments of 2-4. I tried all these sysctl values, I'm currently using the uncommented ones. # cat /etc/sysctl.conf # high net.core.netdev_max_backlog = 3000000 net.core.rmem_max = 16000000 net.core.rmem_default = 8000000 # defaults #net.core.netdev_max_backlog = 1000 #net.core.rmem_max = 131071 #net.core.rmem_default = 163480 # moderate #net.core.netdev_max_backlog = 10000 #net.core.rmem_max = 33554432 #net.core.rmem_default = 33554432 Here's an example of an interface stats report with ethtool.

With and without, it's the same. This is what my interrupt stats looked like before the upgrade, after, with ACPI on PCI it showed multiple NICs bound to an interrupt and shared with other devices such as USB drives which I didn't like so I think i'm going to keep it with ACPI off as it's easier to designate sole purpose interrupts. Is there any advantage I would have using the default i.e. ACPI w/ PCI. ? # cat /etc/default/grub | grep CMD_LINE GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 noacpi pci=noacpi" GRUB_CMDLINE_LINUX="" # cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 45 0 0 16 IO-APIC-edge timer 1: 1 0 0 7936 IO-APIC-edge i8042 2: 0 0 0 0 XT-PIC-XT-PIC cascade 6: 0 0 0 3 IO-APIC-edge floppy 8: 0 0 0 1 IO-APIC-edge rtc0 9: 0 0 0 0 IO-APIC-edge acpi 12: 0 0 0 1809 IO-APIC-edge i8042 14: 1 0 0 4498 IO-APIC-edge ata_piix 15: 0 0 0 0 IO-APIC-edge ata_piix 16: 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb2 18: 0 0 0 1350 IO-APIC-fasteoi uhci_hcd:usb4, radeon 19: 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb3 23: 0 0 0 4099 IO-APIC-fasteoi ehci_hcd:usb1 38: 0 0 0 61963 IO-APIC-fasteoi megaraid 48: 0 0 1002319 4 IO-APIC-fasteoi eth0 49: 0 0 38772 3 IO-APIC-fasteoi eth1 77: 0 0 130076 432159 IO-APIC-fasteoi eth4 78: 0 0 0 23917 IO-APIC-fasteoi eth5 82: 1329033 0 0 4 IO-APIC-fasteoi eth2 83: 0 4886525 0 6 IO-APIC-fasteoi eth3 NMI: 5 6 4 5 Non-maskable interrupts LOC: 61409 57076 64257 114764 Local timer interrupts SPU: 0 0 0 0 Spurious interrupts IWI: 0 0 0 0 IRQ work interrupts RES: 17956 25333 13436 14789 Rescheduling interrupts CAL: 22436 607 539 478 Function call interrupts TLB: 1525 1458 4600 4151 TLB shootdowns TRM: 0 0 0 0 Thermal event interrupts THR: 0 0 0 0 Threshold APIC interrupts MCE: 0 0 0 0 Machine check exceptions MCP: 16 16 16 16 Machine check polls ERR: 0 MIS: 0 Here's sample output of vmstat, showing the system.

I can't figure out why my PCI-X slots are negotiated as PCI. The network cards are all PCI-X with the exception of the integrated NICs that came with the server. In the output below it looks as if eth3 and eth2 negotiated at PCI-X speeds rather than PCI:66Mhz. Wouldn't they all drop to PCI:66Mhz? If your integrated NICs are PCI, as labeled below (eth0,eth1), then wouldn't all devices on your bus speed drop down to that slower bus speed?

  • Cox Communications' Strategic Approach to Enterprise User Experience: How Change Management and Usab

    - by Applications User Experience
    Author: Anna Wichansky, Senior Director, Applications User Experience, and Chair, Oracle Usability Advisory Board As part of our work in the User Experience group, our teams often go to Customer events such as the Higher Education User Group (HEUG) conference, Alliance 2010. This year's event was held in San Antonio, Texas, and was attended by hundreds of higher education, government, and public sector users of Oracle applications. The User Assistance team used this opportunity to reach out to customers in the Educational and Government sectors to better understand how their organizations are currently approaching help, messages, and other forms of user assistance. What is User Assistance? For us, user assistance is more than the old books of users' manuals and documentation. User assistance is anything that helps users get their jobs done quickly and efficiently. Instead of expecting users to stop and look through a guide or manual, we have been developing solutions that are embedded within the interface. We know that when people are having difficulty with a task, they want to be able to search efficiently for solutions and collaborate with coworkers. We know that they want to find their answers right there, right then, so that they can get on with their work. In our interviews at Alliance, we wanted to learn what the participants could tell us about what was happening on their campuses and in their institutions. Figure 1. For Oracle User Assistance, it's not just about books any more. So what did we do? Off to Texas, we recruited 10 people from nine different government and education organizations to come to our Oracle User Experience Onsite Usability Labs. We conducted one-hour interviews with these folks and asked them all about User Assistance--what people are doing, what they would like to do, what technologies they are using, what they would like to use, and ultimately what should we as a company be planning for our future products. We used this as an opportunity also to show them some of our design concepts for Fusion User Assistance, our next generation of user assistance based on the best of our user assistance in other products. Figure 2. Interviewing a technical user at Alliance. What we learned... People are not using paper or online manuals anymore. They don't want to see a manual that is written for technical users and that doesn't make sense to the ordinary end user. They really don't want to have to flip through a manual trying to find an answer to their question. Even when the answer might be tailored to their organization, they don't want to dig through documentation. When they need an answer now, they don't have the patience to dig for something that might or might not be clearly written. What does it mean to an organization when users don't want to deal with documentation? In many cases, it means that frustrated users make phone calls to try to find the answers that they need immediately. Phone calls are expensive to an organization and frustrating to the technical support staff who have provided documentation that no one wants to read anymore. If they don't call, they email for help often, and many users are asking for the same information. The bottom line is that if they could get that help immediately in the interface, they wouldn't have to make those calls or send those emails -- and that saves time and money. Our Fusion User Assistance options to customize help and get help for the task immediately were seen as an opportunity by these technical users to build the solutions that their users need and want. Figure 3. Joyce Ohgi and Laurie Pattison of Applications UX. Chicken Fried Steak. That was huge. But then, this was Texas, where we discovered a lot of things come very big. Drinks are served in quart-size glasses and dishes like Chicken Fried Steaks are served on platters not plates. We saw three-pound cinnamon rolls that you down with tea sweet enough to curl your hair. Deep in the heart of Texas, we learned a lot, and we ate even more.

  • Chrome Web Browser Messages: Some Observations

    - by ultan o'broin
    I'm always on the lookout for how different apps handle errors and what kind of messages are shown (I probably need to get out more), I use this 'research' to reflect on our own application error messages patterns and guidelines and how we might make things better for our users in future. Users are influenced by all sorts of things, but their everyday experiences of technology, and especially what they encounter on the internet, increasingly sets their expectations for the enterprise user experience too. I recently came across a couple of examples from Google's Chrome web browser that got me thinking. In the first case, we have a Chrome error about not being able to find a web page. I like how simple, straightforward messaging language is used along with an optional ability to explore things a bit further--for those users who want to. The 'more information' option shows the error encountered by the browser (or 'original' error) in technical terms, along with an error number. Contrasting the two messages about essentially the same problem reveals what's useful to users and what's not. Everyone can use the first message, but the technical version of the message has to be explicitly disclosed for any more advanced user to pursue further. More technical users might search for a resolution, using that Error 324 number, but I imagine most users who see the message will try again later or check their URL again. Seems reasonable that such an approach be adopted in the enterprise space too, right? Maybe. Generally, end users don't go searching for solutions based on those error numbers, and help desk folks generally prefer they don't do so. That's because of the more critical nature of enterprise data or the fact that end users may not have the necessary privileges to make any fixes anyway. What might be more useful here is a link to a trusted source of additional help provided by the help desk or reputable community instead. This takes me on to the second case, this time more closely related to the language used in messaging situations. Here, I first noticed by the using of the (s) approach to convey possibilities of there being one or more pages at the heart of the problem. This approach is a no-no in Oracle style terms (the plural would be used) and it can create translation issues (though it is not a show-stopper). I think Google could have gone with the plural too. However, of more interest is the use of the verb "kill", shown in the message text and as an action button label. For many writers, words like "kill" and "abort" are to be avoided as they can give offense. I am not so sure about that judgment, as really their use cannot be separated from the context. Certainly, for more technical users, they're fine and have been in use for years, so I see no reason to avoid these terms if the audience has accepted them. Most end users too, I think would find the idea of "kill" usable and may even use the term in every day speech. Others might disagree--Apple uses a concept of Force Quit, for example. Ultimately, the only way to really know how to proceed is to research these matter by asking users of differing roles and expertise to perform some tasks, encounter these messages and then make recommendations based on those findings for our designs. Something to do in 2011!

  • Is a university education really worth it for a good programmer?

    - by Jon Purdy
    The title says it all, but here's the personal side of it: I've been doing design and programming for about as long as I can remember. If there's a programming problem, I can figure it out. (Though admittedly StackOverflow has allowed me to skip the figuring out and get straight to the doing in many instances.) I've made games, esoteric programming languages, and widgets and gizmos galore. I'm currently working on a general-purpose programming language. There's nothing I do better than programming. However, I'm just as passionate about design. Thus when I felt leaving high school that my design skills were lacking, I decided to attend university for New Media Design and Imaging, a digital design-related major. For a year, I diligently studied art and programmed in my free time. As the next year progressed, however, I was obligated to take fewer art and design classes and more technical classes. The trouble was of course that these classes were geared toward non-technical students, and were far beneath my skill level at the time. No amount of petitioning could overcome the institution's reluctance to allow me to test out of such classes, and the major offered no promise for any greater challenge in the future, so I took the extreme route: I switched into the technical equivalent of the major, New Media Interactive Development. A lot of my credits moved over into the new major, but many didn't. It would have been infeasible to switch to a more rigorous technical major such as Computer Science, and having tutored Computer Science students at every level here, I doubt I would be exposed to anything that I haven't already or won't eventually find out on my own, since I'm so involved in the field. I'm now on track to graduate perhaps a year later than I had planned, which puts a significant financial strain on my family and my future self. My schedule continues to be bogged down with classes that are wholly unnecessary for me to take. I'm being re-introduced to subjects that I've covered a thousand times over, simply because I've always been interested in it all. And though I succeed in avoiding the cynical and immature tactic of failing to complete work out of some undeserved sense of superiority, I'm becoming increasingly disillusioned by the lack of intellectual stimulation. Further, my school requires students to complete a number of quarters of co-op work experience proportional to their major. My original major required two quarters, but my current requires three, delaying my graduation even more. To top it all off, college is putting a severe strain on my relationship with my very close partner of a few years, so I've searched diligently for co-op jobs in my area, alas to no avail. I'm now in my third year, and approaching that point past which I can no longer handle this. Either I keep my head down, get a degree no matter what it takes, and try to get a job with a company that will pay me enough to do what I love that I can eventually pay off my loans; or I cut my losses now, move wherever there is work, and in six months start paying off what debt I've accumulated thus far. So the real question is: is a university education really more than just a formality? It's a big decision, and one I can't make lightly. I think this is the appropriate venue for this kind of question, and I hope it sticks around for the sake of others who might someday find themselves in similar situations. My heartfelt thanks for reading, and in advance for your help.

    - by Bob Rhubart
    Every day ArchBeat searches the web for content created by and for community members, and then shares that content via social media. Here's the list of the Top 10 most popular items posted on the OTN ArchBeat Facebook Page for November 2012. One-Stop Shop for Oracle Webcasts Webcasts can be a great way to get information about Oracle products without having to go cross-eyed reading yet another document off your computer screen. Oracle's new Webcast Center offers selectable filtering to make it easy to get to the information you want. Yes, you have to register to gain access, but that process is quick, and with over 200 webcasts to choose from you know you'll find useful content. OAM/OVD JVM Tuning Vinay from the Oracle Fusion Middleware Architecture Group (otherwise known as the A-Team) shares a process for analyzing and improving performance in Oracle Virtual Directory and Oracle Access Manager. White Paper: Oracle Exalogic Elastic Cloud: Advanced I/O Virtualization Architecture for Consolidating High-Performance Workloads This new white paper by Adam Hawley (with contributions from Yoav Eilat) describes in great detail the incorporation into Oracle Exalogic of virtualized InfiniBand I/O interconnects using Single Root I/O Virtualization (SR-IOV) technology. Architected Systems: "If you don't develop an architecture, you will get one anyway..." "Can you build a system without taking care of architecture?," asks Manuel Ricca. "You certainly can. But inevitably the system will be unbalanced, neglecting the interests of key stakeholders, and problems will soon emerge." Backup and Recovery of an Exalogic vServer via rsync "On Exalogic a vServer will consist of a number of resources from the underlying machine," says the man known only as Donald. "These resources include compute power, networking and storage. In order to recover a vServer from a failure in the underlying rack all of these components have to be thoughts about. This article only discusses the backup and recovery strategies that apply to the storage system of a vServer."
