  • Setting static IP on CentOS without system-config-network

    - by Josh
    Background information: I have a problem installing system-config-network. It appears it cannot find an update to sqlite (checks every mirror and comes back empty handed.) I have tried the skipping broken option and package cleanups from yum-utils. Since I cannot get it installed, I decided to set an ip manually from console. A quick Google search comes back empty handed as for an easy how-to guide that works. What do I need to do for a currently configured DHCP ip to change it to a Static IP from console. Thanks, Josh

  • Can't figure out error in Cisco ASA log "regular translation creation failed for icmp ..."

    - by Martijn Heemels
    Every few seconds our new Cisco ASA 5505 firewall is logging errors that I can't figure out with my limited Cisco experience. Severity Date Time Syslog ID Source IP Destination IP Description 3 Mar 25 2010 17:21:14 305006 8.8.8.8 regular translation creation failed for icmp src inside:10.10.0.200 dst outside:8.8.8.8 (type 3, code 3) 3 Mar 25 2010 17:18:37 305006 8.8.4.4 regular translation creation failed for icmp src inside:10.10.0.200 dst outside:8.8.4.4 (type 3, code 3) The logged inside IP is our internal DNS resolver, and the outside IP's are Google's public DNS servers. ICMP Type 3 Code 3 means "Port Unreachable" Our "outside" interface has a fixed IP and our "inside" interface is in the 10.10.0.0/16 subnet. The 'Inspect DNS' Service Policy is enabled, with the preset DNS inspection map. Furthermore there's an ACL that allows all inbound ICMP on the "outside" interface. I've spent hours trying to figure this one out, so any and all advice is welcome!

    - by chris.kawalek(at)oracle.com
    The HIMSS Conference is an extremely important industry trade show put on by The Healthcare Information and Management Systems Society. It's being held in Florida starting this Sunday, February 20th. Their slogan, "Linking people, potential, and progress" could be true of Oracle desktop virtualization as well! The Oracle desktop virtualization group has worked very closely with the Oracle healthcare business unit to have a large presence at this show, and I wanted to tell you a bit about what we're doing: - All Oracle demos are being done on Sun Ray Clients That's right, every demo pod in the large Oracle booth will have a Sun Ray Client with each demo tied to a smart card. Too many people at your demo station? Pop your card out and go to a different one. We'll also be demoing Oracle desktop virtualization at a dedicated demo station, too. This is great stuff! Find Oracle at booth #1651 Oracle's page about HIMSS - Focus Group - Caregiver Mobility with Oracle Sun Ray Clients and Desktop Virtualization Feb 22, 3:15-4:15 PM This focus group will be for customers interested in Oracle desktop virtualization.

  • Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E

    - by Sebastian Bugiu
    I had Ubuntu 11.10 and in the last few weeks I experienced an obscure problem: after I had the computer running for a few days I could no longer connect to google.com or anything related to google. All sites worked with all browsers (Firefox, chrome, opera) except google. It remained in the connecting phase for a few minutes and either timed out or finally connected with this huge delay. Even if I entered other sites such as this one, if it had anything to do with google such adsense or gstatic or whatever with g in it, that site took a long time to load waiting in connecting to gstatic.com . Anything google related took minutes to work, but everything else worked instantly! I tried rebooting or using other machine(with windows on it) and this worked, so it's not network related. But after a few days it started not working again... So I upgraded to the Precise Pangolin hoping this behavior would go away. It didn't! After a few days I get the same behavior as in 11.10. What am I supposed to do? Reboot every other day? I didn't have this problem with neither 10.10 or 11.04. I found the Realtek RTL8168/8111E issue with the r8169 driver but this is not exactly the same card so probably trying r8168 won't help. Ethernet controller: Realtek Semiconductor Co., Ltd.

  • Productivity Tips

    - by Brian T. Jackett
    A few months ago during my first end of year review at Microsoft I was doing an assessment of my year.  One of my personal goals to come out of this reflection was to improve my personal productivity.  While I hear many people say “I wish I had more hours in the day so that I could get more done” I feel like that is the wrong approach.  There is an inherent assumption that you are being productive with your time that you already have and thus more time would allow you to be as productive given more time.    Instead of wishing I could add more hours to the day I’ve begun adopting a number of processes or behavior changes in my personal life to make better use of my time with the goal of improving productivity.  The areas of focus are as follows: Focus Processes Tools Personal health Email Note: A number of these topics have spawned from reading Scott Hanselman’s blog posts on productivity, reading of David Allen’s book Getting Things Done, and discussions with friends and coworkers who had great insights into this topic.   Focus Pre-reading / viewing: Overcome your work addiction Millennials paralyzed by choice Its Not What You Read Its What You Ignore (Scott Hanselman video)    I highly recommend Scott Hanselman’s video above and this post before continuing with this article.  It is well worth the 40+ mins price of admission for the video and couple minutes for article.  One key takeaway for me was listing out my activities in an average week and realizing which ones held little or no value to me.  We all have a finite amount of time to work each day.  Do you know how much time and effort you spend on various aspects of your life (family, friends, religion, work, personal happiness, etc.)?  Do your actions and commitments reflect your priorities?    The biggest time consumers with little value for me were time spent on social media services (Twitter and Facebook), playing an MMO video game, and watching TV.  I still check up on Facebook, Twitter, Microsoft internal chat forums, and other services to keep contact with others but I’ve reduced that time significantly.  As for TV I’ve cut the cord and no longer subscribe to cable TV.  Instead I use Netflix, RedBox, and over the air channels but again with reduced time consumption.  With the time I’ve freed up I’m back to working out 2-3 times a week and reading 4 nights a week (both of which I had been neglecting previously).  I’ll mention a few tools for helping measure your time in the Tools section.   Processes    Do not multi-task.  I’ll say it again.  Do not multi-task.  There is no such thing as multi tasking.  The human brain is optimized to work on one thing at a time.  When you are “multi-tasking” you are really doing 2 or more things at less than 100%, usually by a wide margin.  I take pride in my work and when I’m doing something less than 100% the results typically degrade rapidly.    Now there are some ways of bending the rules of physics for this one.  There is the notion of getting a double amount of work done in the same timeframe.  Some examples would be listening to podcasts / watching a movie while working out, using a treadmill as your work desk, or reading while in the bathroom.    Personally I’ve found good results in combining one task that does not require focus (making dinner, playing certain video games, working out) and one task that does (watching a movie, listening to podcasts).  I believe this is related to me being a visual and kinesthetic (using my hands or actually doing it) learner.  I’m terrible with auditory learning.  My fiance and I joke that sometimes we talk and talk to each other but never really hear each other.   Goals / Tasks    Goals can give us direction in life and a sense of accomplishment when we complete them.  Goals can also overwhelm us and give us a sense of failure when we don’t complete them.  I propose that you shift your perspective and not dwell on all of the things that you haven’t gotten done, but focus instead on regularly setting measureable goals that are within reason of accomplishing.    At the end of each time frame have a retrospective to review your progress.  Do not feel guilty about what you did not accomplish.  Feel proud of what you did accomplish and readjust your goals for the next time frame to more attainable goals.  Here is a sample schedule I’ve seen proposed by some.  I have not consistently set goals for each timeframe, but I do typically set 3 small goals a day (this blog post is #2 for today). Each day set 3 small goals Each week set 3 medium goals Each month set 1 large goal Each year set 2 very large goals   Tools    Tools are an extension of our human body.  They help us extend beyond what we can physically and mentally do.  Below are some tools I use almost daily or have found useful as of late. Disclaimer: I am not getting endorsed to promote any of these products.  I just happen to like them and find them useful. Instapaper – Save internet links for reading later.  There are many tools like this but I’ve found this to be a great one.  There is even a “read it later” JavaScript button you can add to your browser so when you navigate to a site it will then add this to your list. Stacks for Instapaper – A Windows Phone 7 app for reading my Instapaper articles on the go.  It does require a subscription to Instapaper (nominal $3 every three months) but is easily worth the cost.  Alternatively you can set up your Kindle to sync with Instapaper easily but I haven’t done so. SlapDash Podcast – Apps for Windows Phone and  Windows 8 (possibly other platforms) to sync podcast viewing / listening across multiple devices.  Now that I have my Surface RT device (which I love) this is making my consumption easier to manage. Feed Reader – Simple Windows 8 app for quickly catching up on my RSS feeds.  I used to have hundreds of unread items all the time.  Now I’m down to 20-50 regularly and it is much easier and faster to consume on my Surface RT.  There is also a free version (which I use) and I can’t see much different between the free and paid versions currently. Rescue Time – Have you ever wondered how much time you’ve spent on websites vs. email vs. “doing work”?  This service tracks your computer actions and then lets you report on them.  This can help you quantitatively identify areas where your actions are not in line with your priorities. PowerShell – Windows automation tool.  It is now built into every client and server OS.  This tool has saved me days (and I mean the full 24 hrs worth) of time and effort in the past year alone.  If you haven’t started learning PowerShell and you administrating any Windows OS or server product you need to start today. Various blogging tools – I wrote a post a couple years ago called How I Blog about my blogging process and tools used.  Almost all of it still applies today.   Personal Health    Some of these may be common sense or debatable, but I’ve found them to help prioritize my daily activities. Get plenty of sleep on a regular basis.  Sacrificing sleep too many nights a week negatively impacts your cognition, attitude, and overall health. Exercise at least three days.  Exercise could be lifting weights, taking the stairs up multiple flights of stairs, walking for 20 mins, or a number of other "non-traditional” activities.  I find that regular exercise helps with sleep and improves my overall attitude. Eat a well balanced diet.  Too much sugar, caffeine, junk food, etc. are not good for your body.  This is not a matter of losing weight but taking care of your body and helping you perform at your peak potential.   Email    Email can be one of the biggest time consumers (i.e. waster) if you aren’t careful. Time box your email usage.  Set a meeting invite for yourself if necessary to limit how much time you spend checking email. Use rules to prioritize your email.  Email from external customers, my manager, or include me directly on the To line go into my inbox.  Everything else goes a level down and I have 30+ rules to further sort it, mostly distribution lists. Use keyboard shortcuts (when available).  I use Outlook for my primary email and am constantly hitting Alt + S to send, Ctrl + 1 for my inbox, Ctrl + 2 for my calendar, Space / Tab / Shift + Tab to mark items as read, and a number of other useful commands.  Learn them and you’ll see your speed getting through emails increase. Keep emails short.  No one Few people like reading through long emails.  The first line should state exactly why you are sending the email followed by a 3-4 lines to support it.  Anything longer might be better suited as a phone call or in person discussion.   Conclusion    In this post I walked through various tips and tricks I’ve found for improving personal productivity.  It is a mix of re-focusing on the things that matter, using tools to assist in your efforts, and cutting out actions that are not aligned with your priorities.  I originally had a whole section on keyboard shortcuts, but with my recent purchase of the Surface RT I’m finding that touch gestures have replaced numerous keyboard commands that I used to need.  I see a big future in touch enabled devices.  Hopefully some of these tips help you out.  If you have any tools, tips, or ideas you would like to share feel free to add in the comments section.         -Frog Out   Links Scott Hanselman Productivity posts http://www.hanselman.com/blog/CategoryView.aspx?category=Productivity Overcome your work addiction http://blogs.hbr.org/hbsfaculty/2012/05/overcome-your-work-addiction.html?awid=5512355740280659420-3271   Millennials paralyzed by choice http://priyaparker.com/blog/millennials-paralyzed-by-choice   Its Not What You Read Its What You Ignore (video) http://www.hanselman.com/blog/ItsNotWhatYouReadItsWhatYouIgnoreVideoOfScottHanselmansPersonalProductivityTips.aspx   Cutting the cord – Jeff Blankenburg http://www.jeffblankenburg.com/2011/04/06/cutting-the-cord/   Building a sitting standing desk – Eric Harlan http://www.ericharlan.com/Everything_Else/building-a-sitting-standing-desk-a229.html   Instapaper http://www.instapaper.com/u   Stacks for Instapaper http://www.stacksforinstapaper.com/   Slapdash Podcast Windows Phone -  http://www.windowsphone.com/en-us/store/app/slapdash-podcasts/90e8b121-080b-e011-9264-00237de2db9e Windows 8 - http://apps.microsoft.com/webpdp/en-us/app/slapdash-podcasts/0c62e66a-f2e4-4403-af88-3430a821741e/m/ROW   Feed Reader http://apps.microsoft.com/webpdp/en-us/app/feed-reader/d03199c9-8e08-469a-bda1-7963099840cc/m/ROW   Rescue Time http://www.rescuetime.com/   PowerShell Script Center http://technet.microsoft.com/en-us/scriptcenter/bb410849.aspx

  • How to share a folder using the Ubuntu One Web API

    - by Mario César
    I have successfully implement OAuth Authorization with Ubuntu One in Django, Here are my views and models: https://gist.github.com/mariocesar/7102729 Right now, I can use the file_storage ubuntu api, for example the following, will ask if Path exists, then create the directory, and then get the information on the created path to probe is created. >>> user.oauth_access_token.get_file_storage(volume='/~/Ubuntu One', path='/Websites/') <Response [404]> >>> user.oauth_access_token.put_file_storage(volume='/~/Ubuntu One', path='/Websites/', data={"kind": "directory"}) <Response [200]> >>> user.oauth_access_token.get_file_storage(volume='/~/Ubuntu One', path='/Websites/').json() {u'content_path': u'/content/~/Ubuntu One/Websites', u'generation': 10784, u'generation_created': 10784, u'has_children': False, u'is_live': True, u'key': u'MOQgjSieTb2Wrr5ziRbNtA', u'kind': u'directory', u'parent_path': u'/~/Ubuntu One', u'path': u'/Websites', u'resource_path': u'/~/Ubuntu One/Websites', u'volume_path': u'/volumes/~/Ubuntu One', u'when_changed': u'2013-10-22T15:34:04Z', u'when_created': u'2013-10-22T15:34:04Z'} So it works, it's great I'm happy about that. But I can't share a folder. My question is? How can I share a folder using the api? I found no web api to do this, the Ubuntu One SyncDaemon tool is the only mention on solving this https://one.ubuntu.com/developer/files/store_files/syncdaemontool#ubuntuone.platform.tools.SyncDaemonTool.offer_share But I'm reluctant to maintain a DBUS and a daemon in my server for every Ubuntu One connection I have authorization for. Any one have an idea how can I using a web API to programmatically share a folder? even better using the OAuth authorization tokens that I already have.

  • AdSense Mobile Interface – I’m Loving It!

    - by Gopinath
    I love checking AdSense earnings every day on my mobile. All these days my mobile browser, opera, rendered the heavy desktop version of AdSense interface and it was tough to navigate around and see the earnings. To solve the problems of me as well as millions of other AdSense users, Google yesterday released a mobile version of AdSense user interface that works on almost all the mobile platforms – iOS, Android, Windows Phone 7, Symbian and many others. If you have opted for the new beta user interface of AdSense, you will be presented with the mobile version when you https://www.google.com/adsense on your mobile. Here is a screen grab of how looks like on iPhone and Android device.It looks similar on my Nokia mobile too. The Adsense interface for mobile is very nice – on the home page I can quickly have a look at today’s earnings, recent payment amount, last month finalized amount and the total unpaid balances. The quick reports option available the bottom of the screen lets me access a graphical view of useful earnings reports like – Last 7 days, Last 30 days, This Month and Last Month. You can also create your own reports and save them to this list for quick viewing. To view the graphical reports, you don’t need FLASH on your mobile. For more details check out the official post on Google Adsense blog. This article titled,AdSense Mobile Interface – I’m Loving It!, was originally published at Tech Dreams.

  • Best way to implement user-powered data validation

    - by vegetables
    I run a product recommendation engine and I'm hitting a few snags. I'm looking to see if anyone has any recommendations on what I should do to minimize these issues. Here's how the site works: Users come to the site and are presented with product recommendations based on some criteria. If a user knows of a product that is not in our system, they can add it by providing the product name and manufacturer. We take that information, and: Hit one API to gather all the product meta-data (and to validate the product spelling, etc). If the product is not in this first API, we do not allow it in our system. Use the information from step 1 to hit another API for pricing information (gathered from many places online). For the sake of discussion, assume that I am searching both APIs in the most efficient/successful manner possible. For the most part, this works very well. I'd say ~80% of our data is perfectly accurate, but there are a few issues: Sometimes the pricing API (Step 2) doesn't have any information for the product. The way the pricing API is built, it will always return something (theoretically, the closest possible match), and there's no guarantee that the product name is spelled exactly the same way in both APIs, so there's no automated way of knowing if it's the right product. When the pricing API finds the right product, occasionally it has outdated, or even invalid pricing data (e.g. if it screen-scraped the wrong price from a website). Since the site was fairly small at first, I was able to manually verify every product that was added to the website. However, the site has grown to the point where this is taking several hours per day, and is just not efficient use of my time. So, my question is: Aside from hiring someone (or getting an intern) to validate all the data manually, what would be the best system of letting my userbase self-manage the data. Specifically, how can I allow users to edit the data while minimizing the risk of someone ambushing my website, or accidentally setting the data incorrectly.

  • What's the most efficient way to reclaim disk space after deleting lots of data from a database on Sybase ASE 15?

    - by Ernie Longmire
    As I understand it, based on some research but zero real-world experience with Sybase ASE, the only way to reclaim disk space once it's been allocated to a database is to export that database, create a new DB with the same schema, and reload all the exported data to the new database. Is this correct, or is there some other method? Then: assuming the above is correct and a full export-recreate-reload is required, what's the most efficient way to do that? Are there tools that will automate all or part of that process? I'm being told we would have to write separate bcp export and import commands for each and every object in the database, which if true sounds easily scriptable by someone who knows Sybase ASE well enough. (I don't.) This seems to me like a really basic housekeeping task, and it feels like I'm missing something obvious.

  • PHP IDE for Ubuntu Netbook Remix 9.10

    - by Alix Axel
    I've installed Ubuntu Netbook Remix on my netbook and I'm wondering what would be a good IDE to use for mainly PHP development. I've used Komodo Edit in past Linux distributions but it doesn't seem to play well with Ubuntu Network Remix (it doesn't shows up in the remix "desktop", and I don't feel like opening the terminal and typing komodo every time I need to code). I'm considering Eclipse with a PHP plugin, but I've two big problems with Eclipse: I don't like the way it forces me to create a new project when I just want to edit a file. I'm not sure which PHP plugin I should install: Eclipse PDT, PHP Eclipse or Aptana - I don't really understand the differences between Eclipse PDT and PHP Eclipse. Which IDE would you recommend (doesn't need to be Eclipse)? Thanks in advance!

  • Load Average runaway

    - by mewrei
    Is there any way to chase down lockups and runaway load averages? Every so often (pretty randomly) I'll get my load average spike up over 5 usually to around 10-15 and sometimes as high as 75 (dual core machine), and cause my system to lock for an indeterminate amount of time. The only thing I can possibly chase it to is using nVidia fakeraid (RAID-1) with JFS on top of that for my /home partition. Also I noticed that when my load averages spike, the power management system doesn't step up my processor speed from 1.6 to its maximum 2.13Ghz clock speed (not sure if this makes a huge difference with this problem). Any ideas?

    If you’re less than delighted with the default screensaver pack on the Kindle relief is just a simple hack and a reboot away. Read on to learn how to apply a painless jailbreak to your Kindle and create custom screensavers. Unlike jailbreaking other devices like the iPad and Android devices—which usually includes deep mucking about in the guts of your devices and the potential, however remote, for catastrophic bricking—jailbreaking the Kindle is not only extremely safe but Amazon, by releasing the Kindle sourcecode, has practically approved the process with a wink and a nod. Installing the jailbreak and the screensaver hack to replace the default screensavers is so simple we promise you’ll spend 1000% more time messing around making fun screensaver images than you will actually installing the hack. The default screensaver pack for the Amazon Kindle is a collection of 23 images that include portraits of famous authors, woodcarvings from centuries past, blueprints, book reliefs, and other suitably literature-oriented subjects. If you’re not a big fan of the pack—and we don’t blame you if, despite Emily Dickinson being your favorite single lady, you want to mix things up—it’s extremely simple to replace the default screen saver pack with as many custom images as your Kindle can hold. This hack works on every Kindle except the first generation; we’ll be demonstrating it on the brand new Kindle 3 with accompanying notes to direct users with older Kindles.

  • Hosting a website on Heroku.... I know how to, but im running into problems!

    - by Thomas Miller
    I'm starting to learn more on the back-end scale of programing. Recently I started up Heroku for the second or third time. This time I actually installed the Git update to my Mac and installed Heroku in the terminal. I wanted to upload a static html site with the sinatra gem. Everything worked out fine inside the terminal, though I added sinatra after I got everything working and the file with the site hooked up to Heroku. In my logs I did see that I was missing the sinatra gem, so I installed it. My site contains both the proper app.rb and config.ru files. I have nothing showing up online. Just a blank screen! Contacting Heroku on this problem has been very difficult. I get a responce every day, and on every day I respond with a question to the answer that didn't help me at all. 2011-05-18T00:25:20+00:00 app[web.1]: 71.198.0.51 - - [17/May/2011 17:25:20] "GET /favicon.ico HTTP/1.1" 404 18 0.0008 2011-05-18T00:25:20+00:00 heroku[router]: GET pxlc.heroku.com/favicon.ico dyno=web.1 queue=0 wait=0ms service=2ms bytes=313 2011-05-18T00:25:26+00:00 app[web.1]: 71.198.0.51 -

  • Google Updates Google Pack – Pushes Firefox and Skype Away

    - by Gopinath
    Google Pack is a must to install software package on every new Windows PC. With a single installer Google Pack delivers all the useful Google applications like Gtalk, Google Earth, Picasa, etc. and third party applications Firefox, Skype, Adobe Reader. Today Google updated Google Pack collection and removed competitor products like Firefox and Skype from main page and pushed them to background. The main page of Google Pack now showcases the following software: Google Apps, Google Picasa, Adobe Reader, Google Toolbar for IE, Google Desktop, avast free antivirus, Google Chrome and Google Earth. It’s still possible to install Firefox and Skype through Google Pack by clicking on the link “All Applicatoins” available on the right side menu and selecting the required installers.  As most of the users use the main page to pick the showcased software, Firefox and Skype are going to loose much of Google Pack love. Thanks labnol This article titled,Google Updates Google Pack – Pushes Firefox and Skype Away, was originally published at Tech Dreams. Grab our rss feed or fan us on Facebook to get updates from us.

  • PHP won't load php.ini

    - by Chuck
    I am racking my brain here and I must be doing something really stupid. I'm trying to setup PHP on Win2008 R2/IIS 7.5. I unpacked php538 into c:\php538 and renamed the php.ini-development to php.ini. Then i tried going to a command prompt and running: c:\php358\php -info I get: Configuration File (php.ini) Path => C:\windows Loaded Configuration File => (none)Scan this dir for additional .ini files => (none) Additional .ini files parsed => (none) Loaded Configuration File => (none) Scan this dir for additional .ini files => (none) Additional .ini files parsed => (none) I have tried using php5217. I tried putting php.ini in c:\windows. I tried creating the PHPRC envrionment variable and pointing it to c:\php358. Every time I have the same problem. PHP does not find or load the ini file. If I run: c:\php358\php -c php.ini -info Then it will load the file. But I shouldn't have to do this for PHP to find the file in the same directory, in the Windows directory, or using the environment variable, so I'm stumped. When I try to run PHP from IIS I get a 500 error and I can only assume at this time it is because it can't find and load the php.ini file correctly. I see similar questions on here, but none seem to address the problem I am having.

  • SysAdmin Career Question: Internal or Client Based

    - by Malnizzle
    ServerFault Community, It seems there are two positions SysAdmins find themselves in, either you are working for a non-IT services based single client (your employer) and providing in-house IT support or you work for a company who provides out sourced IT services to multiple clients. Right now I work for a company who does the latter, and I often consider how nice it would be doing the in-house side of things, to just have one network I am focused on and instead of feeling like I have a dozen bosses between clients and internal management, I would just have one set of management and people to appease. There is also the technical aspect of every client wanting something different, and having to manage numerous different technology platforms, or trying to force clients into using the technologies we prefer, neither situation is enjoyable. Is this just "the grass is greener on the other side" syndrome, or is there some legitimacy to the the stress of client based IT work compared to being an in-house IT guy? Thanks!

  • Suggested Web Application Framework and Database for Enterprise, “Big-Data” App?

    - by willOEM
    I have a web application that I have been developing for a small group within my company over the past few years, using Pipeline Pilot (plus jQuery and Python scripting) for web development and back-end computation, and Oracle 10g for my RDBMS. Users upload experimental genomic data, which is parsed into a database, and made available for querying, transformation, and reporting. Experimental data sets are large and have many layers of metadata. A given experimental data record might have a foreign key relationship with a table that describes this data point's assay. Assays can cover multiple genes, which can have multiple transcript, which can have multiple mutations, which can affect multiple signaling pathways, etc. Users need to approach this data from any point in those layers in the metadata. Since all data sets for a given data type can run over a billion rows, this results in some large, dynamic queries that are hard to predict. New data sets are added on a weekly basis (~1GB per set). Experimental data is never updated, but the associated metadata can be updated weekly for a few records and yearly for most others. For every data set insert the system sees, there will be between 10 and 100 selects run against it and associated data. It is okay for updates and inserts to run slow, so long as queries run quick and are as up-to-date as possible. The application continues to grow in size and scope and is already starting to run slower than I like. I am worried that we have about outgrown Pipeline Pilot, and perhaps Oracle (as the sole database). Would a NoSQL database or an OLAP system be appropriate here? What web application frameworks work well with systems like this? I'd like the solution to be something scalable, portable and supportable X-years down the road. Here is the current state of the application: Web Server/Data Processing: Pipeline Pilot on Windows Server + IIS Database: Oracle 10g, ~1TB of data, ~180 tables with several billion-plus row tables Network Storage: Isilon, ~50TB of low-priority raw data

Part of my application uses several SPARQL queries like so: const string ArtistByRdfsLabel = @" PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> SELECT DISTINCT ?artist WHERE {{ {{ ?artist rdf:type <http://dbpedia.org/ontology/MusicalArtist> . ?artist rdfs:label ?rdfsLabel . }} UNION {{ ?artist rdf:type <http://dbpedia.org/ontology/Band> . ?artist rdfs:label ?rdfsLabel . }} FILTER ( str(?rdfsLabel) = '{0}' ) }}"; string Query = String.Format(ArtistByRdfsLabel, Artist); I don't like the idea of keeping all these queries in the same class that I'm using them in so I thought I would just move them into their own dedicated class to remove clutter in my RestClient class. I'm used to working with SQL Server and just wrapping every query in a stored procedure but since this is not SQL Server I'm scratching my head on what would be the best for these SPARQL queries. Are there any better approaches to storing these queries using any special C# language features (or general, non C# specific, approaches) that I may not already know about? EDIT: Really, these SPARQL queries aren't anything special. Just blobs of text that I later want to grab, insert some parameters into via String.Format and send in a REST call. I suppose you could think of them the same as any SQL query that is kept in the application layer, I just never practiced keeping SQL queries in the application layer so I'm wondering if there are any "standard" practices with this type of thing.

  • Cryptographic Validation Explained

    - by MarkPearl
    We have been using LogicNP’s CryptoLicensing for some of our software and I was battling to understand how exactly the whole process worked. I was sent the following document which really helped explain it – so if you ever use the same tool it is well worth a read. Licensing Basics LogicNP CryptoLicensing For .Net is the most advanced and state-of-the art licensing and copy protection system you can use for your software. LogicNP CryptoLicensing System uses the latest cryptographic technology to generate and validate licenses. The cryptographic algorithm used is the RSA algorithm which consists of a pair of keys called as the generation key and the validation key. Data encrypted using the generation key can only be decrypted using the corresponding validation key. How does cryptographic validation work? When a new license project is created, a unique validation-generation key pair is created for the project. When LogicNP CryptoLicensing For .Net generates licenses, it encrypts the license settings using the generation key. The validation key can be safely distributed with your software and is used during validation. During license validation, LogicNP CryptoLicensing For .Net attempts to decrypt the encrypted license code using the validation key. If the decryption is successful, this means that the data was encrypted using the generation key, since only the corresponding validation key can decrypt data encrypted with the generation key. This further means that not only is the license valid but that it was generated by you and only you since nobody else has access to the generation key. Generation Key This key is used by CryptoLicensing Generator to generate encrypted license codes. This key is stored in the license project file, so the license project file must be kept secure and confidential and must be accorded the same care as any other critical asset such as source code. Validation Key This key is used for validating generated license codes. It is the same key displayed in the 'Get Validation Key And Code' dialog (Ctrl+K) and is used by your software when validating license codes (using LogicNP.CryptoLicensing.dll). Unlike the generation key, it is not necessary to keep this key secure and confidential. Note that the generation key pair is stored in the project file created by LogicNP CryptoLicensing For .Net, so it is very important to backup this file and to keep it secure. Once the file is lost, it is not possible to retrieve the key pair. FAQ Do I use the same validation key to validate all license codes? Yes, the validation key (and generation key) for the project remains the same; you use the same key to validate all license codes generated using the project. You can retrieve the validation key using the "Project" menu --> "Get Validation Key & Code" menu item. Can license codes generated using generation key from one project be validated using validation key of another project? No! Q. Is every generated license code unique? A. Yes, every license code generated by CryptoLicensing is guaranteed to be unique, even if you generate thousands of codes at a time. Q. What makes CryptoLicensing so secure? A. CryptoLicensing uses the latest cryptographic technology to generate and validate licenses. The cryptographic algorithm used is the RSA asymmetric key algorithm which can use upto 3072-bit keys. Given current computing power, it takes years to break a 3072-bit key. Q. Is is possible for a hacker to develop a keygen for my software? A. Impossible. The cryptographic algorithm used by CryptoLicensing consists of a pair of keys called as the generation key and the validation key. Data encrypted with one key can only be decrypted by the other key and vice versa. Licenses are generated using the generation key and validated using the validation key. Without the generation key, it is impossible to generate valid licenses. Q. What is the difference between validation key and generation key? Generation Key This key is used by CryptoLicensing Generator to generate encrypted license codes. This key is stored in the license project file, so the license project file must be kept secure and confidential and must be accorded the same care as any other critical asset such as source code. Validation Key This key is used for validating generated license codes. It is the same key displayed in the 'Get Validation Key And Code' dialog (Ctrl+K) and is used by your software when validating license codes (using LogicNP.CryptoLicensing.dll). Unlike the generation key, it is not necessary to keep this key secure and confidential. Q. Do I have to include the license project file (.licproj) with my software? A. No!!! This goes against the very essence of the security of the asymmetric cryptographic scheme because the project file contains both the validation and generation key. With your software, you only need to include the validation key which will be used to validate licenses generated by CryptoLicensing using the generation key. The license project file should be treated as any other valuable and confidential asset such as your source code. Q. Does the license service need the license project file? A. Yes. The license project file is needed whenever new licenses are generated (via the UI, via the API or via the license service). As just one example, the license service generates new machine-locked licenses when activated licenses are presented to it for activation, therefore the license service needs the license project file. Q. Is it possible to embed my own data in the generated licenses? A. Yes. You can embed any amount of additional data in the licenses. This data will have the same amount of security as the license code itself and will be tamper-proof. The embedded user data can be retrieved from your software. Q. What additional steps can I take to ensure that my software does not get cracked? A. There are many methods and techniques which can make it extremely difficult for a hacker to crack your software. See Writing Effective License Checking Code And Designing Effective Licenses for more information. Q. Why is the license service not working? A. The most common cause is not setting the CryptoLicense.LicenseServiceURL property before trying to validate a license. Make sure that this property is set to the correct URL where your license service is hosted. The most common cause after this is that the license project file on the web server where your license service is hosted is not the latest. This happens if you make changes to the license project (for example, set the 'Enable With Serials' setting for a profile), but don't upload the updated project file to your web server. Q. Why are my serials not working? Serial codes require the user of a license service. See Using Serial Codes for more details. Also see the earlier question 'Why is the license service not working?' Q. Is the same validation key used to validate license codes generated from different profiles. A. Yes. Profiles are just pre specified license settings for quickly generating licenses having those settings. The actual license code is still generated using the license project's cryptographic generation key and thus, can be validated using the project's validation key. Q. Why are changes made to a profile not getting saved? A. Simply changing license settings via UI and saving the license project does not save those license settings to the active profile. You must first save the license settings to a profile using the Save/Save As command from the Profiles menu (see above). Q. Why is validation of activated licenses failing from CryptoLicensing Generator, but works from my software? A. Make sure that you have specified the URL of the license service using the Project Properties Dialog. Also see the earlier question 'Why is the license service not working?' Q. How can I extend the trial period of my customer? A. To extend the evaluation period of the customer, simply send him a new license code specifying the desired evaluation limits. Evaluation information such as the current used days, executions, etc are stored in garbled form in a registry location which is derived from the license code. Therefore, when a new license code is used, the old evaluation information will not be used and a new evaluation period will be started.

  • Firewall behind firewall

    - by Makach
    I've recently changed jobs and I've been set up with a new workstation. On all previous places where I've been working they've had some sort of local firewall installed on each and every workstation - but here I've been told not to activate it because it is not necessary since we're already behind a HW Firewall. To me this seem a bit naïve, but I cannot emphasise it. I always thought a local firewall was good practice, ie. if something managed to come through the hw firewall there might be a slight chance other computers on the lan would block the internal threath. We got free access to internet and we got a virus checker installed.

  • So long and thanks for the fish&hellip;

    - by Geoff N. Hiten
    This marks my last post as a SQLPASS Board member.  I learned a lot during my year of service and I thank everyone involved for this opportunity.  I would especially like to thank the Chapter leaders and Regional Mentors for Virtual Chapters who (mostly) patiently taught me about Virtual Chapters.   I hope the changes I put in place will help strengthen and grow VCs and PASS going forward.  I would also like to thank every one who encouraged me to reach beyond my comfort zone and accept a leadership position within the PASS organization.  My overall principle was to be a good steward of the PASS community.  Could I have done more?  Always. Did I do enough?  I hope so.  But PASS is a volunteer organization and my time, like yours, is limited.  I have other obligations in life that supersede PASS.  Now I have more time for some of those.  I won’t be going away or leaving the SQL Community.  I will still contribute to the community and support PASS, just in a different role.  Time to let somebody else enjoy the hot seat for a while. Finally, everyone who voted (not just for me) deserves a thanks.  More voters and more engaged voters, strong candidates, and a vigorous debate were all I wanted out of declaring as a candidate last year. This year the SQL community got exactly that. Thank you..
