• Enterprise with eyes on NoSQL

  - by thegreeneman

  Since joining Oracle a few months back, I have had the fortune of being able to interact with a number of large enterprise organizations and discuss their current state of adoption for NoSQL database technology.   It is worth noting that a large percentage of these organizations do have some NoSQL use and have been steadily increasing their understanding of its applicability for certain data management workloads.   Thru those discussions I’ve learned that it seems one of the biggest issues confronting enterprise adoption of NoSQL databases is the lack of standards for access, administration and monitoring.    This was not so much of an issue with the early adopters of NoSQL technology because they employed a highly DevOps centric approach to application deployment leaving a select few highly qualified developers with the task of managing the production of the system that they designed and implemented. However, as NoSQL technology moves out of the startup and into the hands of larger corporate entities, developers with a broad skill set that are capable of both development and I.T. type production management are in short supply and quickly get moved on to do new projects, often moving to different roles within the company.  This difference in the way smaller more agile startups operate as compared to more established companies is revealing a gap in the NoSQL technology segment that needs to get addressed.    This is one of places that a company such as Oracle has a leg up in the NoSQL Database front.  A combination of having gone thru a past database maturization process,  combined with a vast set of corporate relationships that have grown hand in hand to solve these types of issues, Oracle is in a great place to lead the way in closing the requirements gap for NoSQL technology.  Oracle's understanding of the needs specific to mature organizations have already made their way into the Oracle’s NoSQL Database offering with features such as:  One click cluster deployment with visual topology planning,  standards based monitoring protocols such as SNMP, support for data access for reporting via standard SQL  and integration with emerging standards for data access such as MapReduce.  Given the exciting developments we’re driving in the Oracle NoSQL Database group, I will have a lot more to say about this topic as we move into the second half of the year.

• career planning advice [closed]

  Possible Duplicate: Are certifications worth it? I am at the point in my career where people start to veer off into either management-type roles or they focus on solidifying their technical skills to stay in the development game for the long-haul. Here's my story: I've got a degree in economics, an MA in Political Science and an MBA in Finance and Management. In addition, I've done coursework in advanced math and software development (although no degree in math or software). All-in-all, I've got 13 years of post-secondary education under my belt. I, however, currently work as a software developer using C# for desktop, Silverlight, Flex and javascript for web, and objective c for mobile. I've been in software development for the past 3.3 years, and it seems like it comes pretty easy to me. I work in a field called "geospatial information systems," which just involves customization and manipulation of geospatial data. Right now I am looking at one of several certifications. Given this background, which of these certifications has the highest ceiling? CFA PMP various development/technological certifications from Microsoft, etc. Other? My academic and work experience are all heavy on the analytical/development side, esp. so given the MBA and the B.S. in Econ. The political science degree was really a lot of stats. So it seems that I would be good pursuing more of the CFA/analytical role. This is a difficult path, however, because I have no work experience in the financial sector, and the developers in finance are all "quants," which again, I am OK with, but I haven't done much statistical modeling in the past 3.3 years. The PMP would require knowledge of best practices as it pertains explicitly to software development. I also don't enjoy a lot of business travel, a common theme for most PMP jobs I've seen. If certifications is the route, which would you recommend? Anything else? I've thought about going back to try to knock out a B.S. in C.S., but I wasn't sure how long that would take, or what would be involved. Thoughts or recommendations? Thanks in advance! I turn 32 this weekend, which is what has forced me to think about these issues.

• Extract first page from multiple pdfs

  - by Tim Alexander

  Have got about 500 PDFs to go through and extract the first page of. They then need to go through some time consuming conversion process so was hoping to try and save some time by have a batch process to extract just the first page from the 500 pdfs and place it in a new pdf. Have had a poke around Acrobat but can find no real method of doing this for multiple files. Does anyone know any other programs or methods that this could be achieved? Free and open source are obviously more favourable :) EDIT: Have actually had some success using GhostScript to extract just one page. Am now looking at how to batch that and take the list of files and use those.

• Interview Questions [closed]

  - by Pemdas

  Possible Duplicate: What techniques do you use when interviewing developers? Nearly every SE interviewing process has some sort of coding exercise to prove that the interviewee can actually write code. More often then not, the exercise also hopes to demonstrate that the interviewee can solve problems. However, this is often not sufficient enough to determine if the interviewee can actually design software. What are some effective ways to determine if an interviewee understands the basic concepts of design such as abstraction, interface design, thread management, ...ect?

• lighttpd silently stops logging

  - by Max Cantor

  I'm on a Slicehost 256MB VPS with Ubuntu 9.04 (Jaunty). lighttpd is the only web server process running; it listens on port 80. My lighttpd.conf can be found here. I'm using Ubuntu's default logrotate setup for lighty. At seemingly random times, lighttpd will stop logging. It is not correlated with log rotation--that is, the errors do not occur when logrotate kicks in. What happens is, I will verify that the server is serving files by hitting a URL with my browser, and I will verify that it is not logging by checking access.log and seeing that the GET request I just made is not there. Using init.d to restart the process starts logging again, without truncating or rotating the log file. That is, new requests will be logged at the end of the existing access.log file. There are no cron jobs running on this box. Any ideas?

• Automatic document generation

  - by Bowler

  I have some data in an excel file from which I have to generate a report. I repeat this task fairly regularly and am looking to automate it. I have a LaTeX project into which I usually just copy data by hand, export the necessary worksheets as pdfs and add them to my LaTeX project and compile with pdflatex. It has occured to me that there must be a way to automate this process. Is there an efficient way to export the data from excel and into a LaTeX project, possibly a vba script in excel could run the process? Also, it doesn't have to be LaTeX, I'm not all that experienced with MS office's more advanced features is there some way akin to a mail merge that I could achieve this with? In some ways this might be better in case I have to pass the work on to someone who doesn't know LaTeX. Thanks.

• mongod fork vs nohup

  - by Daniel Kitachewsky

  I'm currently writing process management software. One package we use is mongo. Is there any difference between launching mongo with mongod --fork --logpath=/my/path/mongo.log and nohup mongod >> /my/path/mongo.log 2>&1 < /dev/null & ? My first thought was that --fork could spawn more processes and/or threads, and I was suggested that --fork could be useful for changing the effective user (downgrading privileges). But we run all under the same user (process manager and mongod), so is there any other difference? Thank you

• How do I disable the sleep button on my keyboard?

  - by KillianDS

  I have a "power button" on my keyboard that enables standby or hibernate. I can't find the mapping of this key anywhere in "sytem settingsKeyboard", "systempower management", "compiz config or similar (where I could find it before unity). How can I disable (not remap) this button? I do not want to disable hibernate/sleep altogether, it's simply this key that gets pressed a lot by accident and it's getting quite annoying.

• Good, simple reasons for having multiple environments

  - by smp7d

  Throughout my career I had worked at companies that had a collection of different environments for different purposes. We always had more or less our desktop environment, a test environment, a QA environment, a staging environment and a production environment. This went for both servers/applications and any data sources we were using. When I started at my current company I found that 90% of the apps were either developed on a desktop environment against production data sources or developed directly on the production server depending on the platform. I wasn't fazed because I was hired in part to make changes to improve the way the development team functioned, which was clear from my interview process. We slowly started to turn the philosophy and pretty soon, most of the apps could be run in either a desktop, test or production environment. Not too long after that staging came around as well. Now most of our developers see the benefit of this methodology and defend it vigilantly. However, we have a number of legacy apps that never got migrated. We also have a number of legacy programmers who think of this as a waste of time. Unfortunately, we got lip service but never full buy-in from management. We got what we thought was a commitment to invest substantially in this about a year ago, but nothing materialized despite the considerable planning that we put into it. Now we are finding that we need more and more environments. We need help from the server/network administration teams for setup and we need participation from the business stakeholders to support the release cycle. We are at a place now where a project can function what I consider "normally" only if you have the right people on the project and the time to set up the proper environments. I'd love to present a complete argument, but management really has no time and interest in hearing me out until there is a critical issue. I can't really articulate the benefits simply as it always just seemed second nature to me. I was wondering if there are any good, simple, irrefutable reasons for the separation of environments that would get managers with no development experience to get behind this idea. Are there any good resources/literature on the topic?

• Why does my CPU Usage reach 100% too often?

  - by deathlock

  I'm using a dual-core processor and often see my CPU usage reaches 100%. I realize this may happen if I'm running too much applications, so when I know the computer starts to run slowly, I start to close my applications. I usually run 4-5 applications simultaneously. Usually those are: web browser (Google Chrome), Adobe Photoshop, Notepad++, XAMPP, and Windows Task Manager. Usually I close tabs in my Chrome first, because I often browse the net with about 20 tabs/4 windows open, so I presume that would take much memory (bad habit, I know). But even after closing Chrome's tabs or closing other applications, my CPU Usage often stays at high percentage - 72% at best, 100% at worst. I check the Processes tab on Windows Task Manager and usually found the System, System Idle Process, or services.exe taking the highest CPU process (could reach 60). Why is this happening? And is there any solution? EDIT I have T2250 @ 1,73 Ghz and 2.5 GB RAM

• rdiff-backup failed due to target machine being down, but is unkillable

  - by Markus

  My backup script was invoked by cron, using rdiff-backup to backup the user files onto a target system in the network. That target computer went down at some point, yet still appeared as mounted on the server. rdiff-backup didn't do anything, but still appears as a process. kill-ing doesn't stop it. Similarly, running rdiff-backup for other directories works but doesn't exit properly and remains in the process list. Is there anything short of rebooting the server that I can try?

• IIS6 + PHP + FastCGI 500 Errors - Where to start looking?

  - by Bertvan

  I've set up IIS6 with FastCGI to use php-cgi.exe. I have some php websites by external parties, that I'm trying to run in a test environment. One of the websites just plain gives me a FastCGI Error Page. Question: Is there some way to enable logging somewhere so that I can get a bit more information on this problem? I have looked in Eventlog IIS Website log (c:\windows\system32\Logfiles) PHP log But no results, except the IIS Website log mentions a return of a 500 page. Question: Is there any other way to debug/check where things might be going wrong? Here is what the page looks like: FastCGI Error The FastCGI Handler was unable to process the request. Error Details: The FastCGI process exited unexpectedly Error Number: -1073741571 (0xc00000fd). Error Description: Unknown Error HTTP Error 500 - Server Error. Internet Information Services (IIS)

• How to check use of userva boot option on Win 2K3 server

  - by Tim Sylvester

  I have some 32-bit Win2K3 servers running an application that fails now and then apparently due to heap fragmentation. (Process virtual bytes grows, private bytes does not) I do not have access to the source code or build process of this application. I have modified the boot.ini file on one of these servers to include /userva=2560, half way between the normal mode of operation and the /3GB option. Normally it takes weeks to reach the point of failure, but I'd like to see right away whether this has actually had any effect. As I understand it, this option limits the kernel to the remaining address space (1536MB instead of 2048), but does not necessarily give an application the extra address space, depending on the flags in the application's PE header. How can I determine whether the O/S is allowing a particular application, running in production, to access address space above 2GB? Additionally, what's the best way to monitor the system to ensure that the kernel is not starved for address space, and more generally how should I go about finding the optimal value for this setting?

• Why is a software development life-cycle so inefficient?

  - by user87166

  Currently the software development lifecycle followed in the IT company I work at is: The "Business" works with a solution manager to build a Business Requirement document The solution manager works with the Program manager to build a Functional Spec The PM works with the engineering lead to develop a release plan and with the engineering team to develop technical specifications If there are any clarifications required, developers contact the PM who contacts the solution manager who contacts the business and all the way back introducing a latency of nearly 24 hours and massive email chains for any clarifications By the time the tech spec is made, nearly 1 month has passed in back and forth Now, 2 weeks go to development while the test writes test cases Code is dropped formally to test, test starts raising bugs. Even if there is 1 root cause for 10 different issues, and its an easily fixed one, developers are not allowed to give fresh code to test for the next 1 week. After 2-3 such drops to test the code is given to the ops team as a "golden drop" ( 2 months passed from the beginning) Ops team will now deploy the code in a staging environment. If it runs stable for a week, it will be promoted to UAT and after 2 weeks of that it will be promoted to prod. If there are any bugs found here, well, applying for a visa requires less paperwork This entire process is followed even if a single SSRS report is to be released. How do other companies process such requirements? I'm wondering why, the business cannot just drop the requirements to developers, developers build and deploy to UAT themselves, expose it to the business who raise functional bugs and after fixing those promote to prod. (even for more complex stuff)

• Running a Screen instance of a program as non-root

  - by user288467

  I've got a dedicated server (Ubuntu 12.04, no GUI) set up to launch an instance of McMyAdmin and attach it to a screen instance every time I reboot the hardware. I have the command saved to root's crontab as: @reboot cd /var/MC_SVR && screen -dmS McMyAdmin ./MCMA2_Linux_x86_64 Problem being, though, I have a user set up specifically for FTP access to the server files so I don't always have to SSH into the machine. Since the server is being started as a root process, all the files it makes are, obviously, set with root as the owner. So I chown'd all the files and set them to ftpuser. Now I'm stuck with trying to get the process to start as ftpuser. I've tried doing the following but to no avail: cd /var/MC_SVR && su ftpuser - -c 'screen -dmS McMyAdmin ./MCMA2_Linux_x86_64' I try this in terminal and I get no errors or anything (in fact I never get anything unless it's a syntax error from su), but there's no screen instance to access and so I can assume the server never starts. So, what am I doing wrong? Or am I just not accessing the screen instance correctly since it's (supposed) to be launched by another user?
