  • Ensuring a repeatable directory ordering in linux

    - by Paul Biggar
    I run a hosted continuous integration company, and we run our customers' code on Linux. Each time we run the code, we run it in a separate virtual machine. A frequent problem that arises is that a customer's tests will sometimes fail because of the directory ordering of their code checked out on the VM. Let me go into more detail. On OSX, the HFS+ file system ensures that directories are always traversed in the same order. Programmers who use OSX assume that if it works on their machine, it must work everywhere. But it often doesn't work on Linux, because linux file systems do not offer ordering guarantees when traversing directories. As an example, consider there are 2 files, a.rb, b.rb. a.rb defines MyObject, and b.rb uses MyObject. If a.rb is loaded first, everything will work. If b.rb is loaded first, it will try to access an undefined variable MyObject, and fail. But worse than this, is that it doesn't always just fail. Because the file system ordering on Linux is not ordered, it will be a different order on different machines. This is worse because sometimes the tests pass, and sometimes they fail. This is the worst possible result. So my question is, is there a way to make file system ordering repeatable. Some flag to ext4 perhaps, that says it will always traverse directories in some order? Or maybe a different file system that has this guarantee?

CPU: GenuineIntel, Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz OS: Linux 2.6.18-128.el5 Memory: 2Gb Background. I am running a small database (MySQL), around 1000 records with each record containing 44 fields. At the start of each day “00:01” the tables are cleared and populated with fresh data. The are 10 remote PCs all running Winodws XP and Firefox internet browser. All remote PC’s are connected to the internet using a min 4Gb broadband connection. Each remote PC runs a URL which displays a dynamic page of data which is refreshed every 20 seconds. This is a continual process 24 hours a day. I problem I am having is on odd occasions throughout the day the PC browser error with “Server taking too long to respond error”. What I am trying to find our is if I have the correct setting in the httpd.conf file on the server. Any help or advice anyone can provide would be very helpful.

  • Oracle Fusion Applications User Experience Design Patterns: Feeling the Love after Launch

    - by mvaughan
    By Misha Vaughan, Oracle Applications User ExperienceIn the first video by the Oracle Applications User Experience team on the Oracle Partner Network, Vice President Jeremy Ashley said that Oracle is looking to expand the ecosystem of support for Oracle’s applications customers as they begin to assess their investment and adoption of Oracle Fusion Applications. Oracle has made a massive investment to maintain the benefits of the Fusion Applications User Experience. This summer, the Applications User Experience team released the Oracle Fusion Applications user experience design patterns.Design patterns help create consistent experiences across devices.The launch has been very well received:Angelo Santagata, Senior Principal Technologist and Fusion Middleware evangelist for Oracle,  wrote this to the system integrator community: “The web site is the result of many years of Oracle R&D into user interface design for Fusion Applications and features a really cool web app which allows you to visualise the UI components in action.”  Grant Ronald, Director of Product Management, Application Development Framework (ADF) said: “It’s a science I don't understand, but now I don't have to ... Now you can learn from the UX experience of Fusion Applications.”Frank Nimphius, Senior Principal Product Manager, Oracle (ADF) wrote about the launch of the design patterns for the ADF Code Corner, and Jürgen Kress, Senior Manager EMEA Alliances & Channels for Fusion MiddleWare and Service Oriented Architecture, (SOA), shared the news with his Partner Community. Oracle Twitter followers also helped spread the message about the design patterns launch: ?@bex – Brian Huff, founder and Chief Software Architect for Bezzotech, and Oracle ACE Director:“Nifty! The Oracle Fusion UX team just released new ADF design patterns.”@maiko_rocha, Maiko Rocha, Oracle Consulting Solutions Architect and Oracle FMW engineer: “Haven't seen any other vendor offer such comprehensive UX Design Patterns catalog for free!”@zirous_chad, Chad Thompson, Senior Solutions Architect for Zirous, Inc. and ADF Developer:Wow - @ultan and company did a great job with the Fusion UX PatternsWhat is a user experience design pattern?A user experience design pattern is a re-usable, usability tested functional blueprint for a particular user experience.  Some examples are guided processes, shopping carts, and search and search results.  Ultan O’Broin discusses the top design patterns every developer should know.The patterns that were just released are based on thousands of hours of end-user field studies, state-of-the-art user interface assessments, and usability testing.  To be clear, these are functional design patterns, not technical design patterns that developers may be used to working with.  Because we know there is a gap, we are putting together some training that will help close that gap.Who should care?This is an offering targeted primarily at Application Development Framework (ADF) developers. If you are faced with the following questions regarding Fusion Applications, you will want to know and learn more:•    How do I build something that looks like Fusion Applications?•    How do I build a next-generation application?•    How do I extend a Fusion Application and maintain the user experience?•    I don’t want to re-invent the wheel on the user interface, so where do I start?•    I need to build something that will eventually co-exist with Fusion Applications. How do I do that?These questions are relevant to partners with an ADF competency, individual practitioners, or small consultancies with an ADF specialization, and customers who are trying to shift their IT staff over to supporting Fusion Applications.Where you can find out more?OnlineOur Fusion User Experience design patterns maven is Ultan O’Broin. The Oracle Partner Network is helping our team bring this first e-seminar to you in order to go into a more detail on what this means and how to take advantage of it:?

  • openssl client authentication error: tlsv1 alert unknown ca: ... SSL alert number 48

    - by JoJoeDad
    I've generated a certificate using openssl and place it on the client's machine, but when I try to connect to my server using that certificate, I error mentioned in the subject line back from my server. Here's what I've done. 1) I do a test connect using openssl to see what the acceptable client certificate CA names are for my server, I issue this command from my client machine to my server: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -prexit and part of what I get back is as follow: Acceptable client certificate CA names /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] 2) Here is what is in the apache configuration file on the server regarding SSL client authentication: SSLCACertificatePath /etc/apache2/certs SSLVerifyClient require SSLVerifyDepth 10 3) I generated a self-signed client certificate called "client.pem" using mypos.pem and mypos.key, so when I run this command: openssl x509 -in client.pem -noout -issuer -subject -serial here is what is returned: issuer= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] subject= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=mlR::mlR/[email protected] serial=0E (please note that mypos.pem is in /etc/apache2/certs/ and mypos.key is saved in /etc/apache2/certs/private/) 4) I put client.pem on the client machine, and on the client machine, I run the following command: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -status -cert client.pem and I get this error: CONNECTED(00000003) OCSP response: no response sent depth=1 /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] verify error:num=19:self signed certificate in certificate chain verify return:0 574:error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s3_pkt.c:1102:SSL alert number 48 574:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s23_lib.c:182: I'm really stumped as to what I've done wrong. I've searched quite a bit on this error and what I found is that people are saying the issuing CA of the client's certificate is not trusted by the server, yet when I look at the issuer of my client certificate, it matches to one of the accepted CA returned by my server. Can anyone help, please? Thank you in advance.

  • Mail.app doesn't detect sender in Address Book

    - by CoreSandello
    Hi there. I don't understand, how does 'smart addresses' in Mail.app work. Recently I mentioned, that for some emails I don't see person's full name in 'From' column. I started to dig into this behavior and found out, that I have few contacts in my Address Book, that are not recognized by Mail.app. Here how it looks: I have a person in Address Book with filled email entry and filled first/last name (localized). I have an incoming email from that person (from email specified in Address Book), but first/last name in the email itself doesn't match with ones specified in Address Book (e. g. 'From' field in email looks like 'John [work] <[email protected]>' while Address Book entry is 'John Smith' (localized, in Russian)). And Mail.app doesn't recognize that this mail is originating from that person in Address Book: if I click on 'From' field, it suggests to me to add sender to Address Book, while for others' emails I have 'Show in Address Book' menu entry (especially for ones with full localized name in 'From' field). I'm wondering, is that behavior correct or I'm missing something? I'm using Snow Leopard & Mail 4.0; my system language set to English, if that matters. I'd like to have some clarifications on that Mail.app behavior: whenever it fixable or not (and if it's fixable, I'd like to see a fix). By the way, is it possible to match sender's address against Address Book entry in filter rules or not? That would be great, if I can create rules like 'move all mail from that person to that folder' without specifying exact source address. Thanks, Ivan.

  • 301 redirect bulk aspx URLs on IIS

    - by tiki16
    We recently relaunched an old ASPX site as a new Drupal site on the same domain. No 301 redirect was implemented. I have outputted a list of 1000 URLs that need to be 301 redirected. Most of the URLs are the results of search queries that were committed on the website. I.E.: http://www.mysite.com/electronics/CommunityDetails.aspx?FirstLetter=%&ID=444 We are running a Drupal site on IIS using a PHP plugin. Is there a way I can wild card a redirect of all ASPX pages? I know I can do it with .htaccess but that doesn't apply here. Any suggestions appreciated.

  • How to improve Windows Server 2008 R2 to handle many connections?

    - by invisal
    It has been a few days so far that I am trying to figure how to solve this problem. First of all, I am running a website with an average daily page view of 350,000. Previously, all ads management (tracking click and impression that each ads has served) and content were served in a single server with the following spec: Server 1 OS: Windows 2008 R2 64-Bit CPU: Intel® Core™ i5 - 4 cores RAM: 8 GB Storage: 2 x 1 TB hard drives Bandwidth: 10 TB per month To improve our website speed, I decided to separate the ads management script to another dedicated server because we have more than 15 advertisers to 30 advertisers per each page. Server 2 OS: Windows 2008 R2 64-Bit CPU: Intel® Core™ i5 - 4 cores RAM: 4 GB Storage: 2 x 300 GB hard drives Bandwidth: 10 TB per month The Problem The problem is that Server 1 can handle both content and ads system. Now, that I take away the ads system and put it at Server 2. Server 2 can barely serve only ads system. Test First of all, I moved 75% of the ads to Server 2. And then, perform a ping to server: ping -t xxxxx. [I did the ping for 10 minutes and its following similar pattern as below] Reply from xxxxx bytes=32 time=290ms TTL=116 Reply from xxxxx bytes=32 time=289ms TTL=116 Reply from xxxxx bytes=32 time=320ms TTL=116 Reply from xxxxx bytes=32 time=286ms TTL=116 Reply from xxxxx bytes=32 time=286ms TTL=116 Reply from xxxxx bytes=32 time=348ms TTL=116 Reply from xxxxx bytes=32 time=284ms TTL=116 Then, I moved 100% of the ads to Server 2. Then, perform a ping to server again.

  • SquidGuard and Active Directory: how to deal with multiple groups?

    - by Massimo
    I'm setting up SquidGuard (1.4) to validate users against an Active Directory domain and apply ACLs based on group membership; this is an example of my squidGuard.conf: src AD_Group_A { ldapusersearch ldap://my.dc.name/dc=domain,dc=com?sAMAccountName?sub?(&(sAMAccountName=%s)(memberOf=cn=Group_A%2cdc=domain%2cdc=com)) } src AD_Group_B { ldapusersearch ldap://my.dc.name/dc=domain,dc=com?sAMAccountName?sub?(&(sAMAccountName=%s)(memberOf=cn=Group_B%2cdc=domain%2cdc=com)) } dest dest_a { domainlist dest_a/domains urllist dest_b/urls log dest_a.log } dest dest_b { domainlist dest_b/domains urllist dest_b/urls log dest_b.log } acl { AD_Group_A { pass dest_a !dest_b all redirect http://some.url } AD_Group_B { pass !dest_a dest_b all redirect http://some.url } default { pass !dest_a !dest_b all redirect http://some.url } } All works fine if an user is member of Group_A OR Group_B. But if an user is member of BOTH groups, only the first source rule is evaluated, thus applying only the first ACL. I understand this is due to how source rule matching works in SquidGuard (if one rule matches, evaluation stops there and then the related ACL is applied); so I tried this, too: src AD_Group_A_B { ldapusersearch ldap://my.dc.name/dc=domain,dc=com?sAMAccountName?sub?(&(sAMAccountName=%s)(memberOf=cn=Group_A%2cdc=domain%2cdc=com)) ldapusersearch ldap://my.dc.name/dc=domain,dc=com?sAMAccountName?sub?(&(sAMAccountName=%s)(memberOf=cn=Group_B%2cdc=domain%2cdc=com)) } acl { AD_Group_A_B { pass dest_a dest_b all redirect http://some.url } [...] } But this doesn't work, too: if an user is member of either one of those groups, the whole source rule is matched anyway, so he can reach both destinations (which is of course not what I want). The only solution I found so far is creating a THIRD group in AD, and assign a source rule and an ACL to it; but this setup grows exponentially with more than two or three destination sets. Is there any way to handle this better?

  • Backup, Migrate or Clone Failing CentOS 4 (LVM)

    - by Hegelworm
    Hello there, I've been running a BlueQuartz CentOS 4 system (Nuonce.net distro) for a few years now and although the hard drive (Deskstar) has always been a bit noisy, on a few recent occasions I've heard it having trouble spinning up. Basically, I want to clone this drive to a similar sized one (80 Gig). I've spent many hours reading upon dd, dd_rescue, rsync, clonezilla and LVM mirroring yet the sheer number of options and nightmarish accounts has left me frozen - unable to make an informed decision as to how to start. I've made a few attempts. dd failed after about 2 hours, as, although the drives appeared to be identical on the surface (ATA Seagate Barracudas, Thai not Chinese), the destination drive is slightly smaller. My most recent attempt involved using a Debian CD to format the new drive and then rsync-ing everything over and editing the new drive's grub and fstab to reflect the changes. No joy here either as I hadn't chosen LVM when partitioning the destination drive and it wouldn't boot. As you can probably tell, I'm out of my depth here and a panic-invoking mixture of caution and frustration has prompted me to sign up here. The server itself, although not strictly a production environment, has a very specific installation of Festival, LAME and ffMpeg and provides the back-end for a Text-to-Speech jQuery plugin that I've built over the last 2 years. I'm also planning to rebuild the whole TTS system on Debian as the existing CentOS system still has PHP4 etc. For now though, I'd really like to just shift everything over to a new drive. As this is my first post, please feel free to lay any house rules on me that I might've overlooked; I've been hovering around StackOverflow for a while now but have only just signed up. Many thanks.

The sample below shows how to define a launch popup listener configured on the launchPopupListener property of the af:inputListOfValues component to filter a list of values. <af:inputListOfValues id="departmentIdId"    value="#{bindings.DepartmentId.inputValue}"                                          model="#{bindings.DepartmentId.listOfValuesModel}"    launchPopupListener="#{PopupLauncher.onPopupLaunch}" … >         … </af:inputListOfValues> A list of values is queried using a search binding that gets created in the PageDef file of a view when a lis of value component gets added. The managed bean code below looks this search binding up to then add a view criteria that filters the query. Note: There is no public API yet available for the FacesCtrlLOVBinding class, which is why I use the internal package class it in the example. public void onPopupLaunch(LaunchPopupEvent launchPopupEvent) {   BindingContext bctx = BindingContext.getCurrent();   BindingContainer bindings = bctx.getCurrentBindingsEntry();   FacesCtrlLOVBinding lov =        (FacesCtrlLOVBinding)bindings.get("DepartmentId");   ViewCriteriaManager vcm =   lov.getListIterBinding().getViewObject().getViewCriteriaManager();             //make sure the view criteria is cleared   vcm.removeViewCriteria(vcm.DFLT_VIEW_CRITERIA_NAME);   //create a new view criteria   ViewCriteria vc =          new ViewCriteria(lov.getListIterBinding().getViewObject());   //use the default view criteria name   //"__DefaultViewCriteria__"   vc.setName(vcm.DFLT_VIEW_CRITERIA_NAME);   //create a view criteria row for all queryable attributes   ViewCriteriaRow vcr = new ViewCriteriaRow(vc);   //for this sample I set the query filter to DepartmentId 60.   //You may determine it at runtime by reading it from a managed bean   //or binding layer   vcr.setAttribute("DepartmentId", 60);   //also note that the view criteria row consists of all attributes   //that belong to the LOV list view object, which means that you can   //filter on multiple attributes   vc.addRow(vcr);             lov.getListIterBinding().getViewObject().applyViewCriteria(vc); }  Note: Instead of using the vcm.DFLT_VIEW_CRITERIA_NAME name you can also define a custom name for the view criteria.

  • How to handle canonical url changes like Stack Overflow

    - by lulalala
    Stack Overflow sites all have pretty urls which include the question title. In the HTML it also have canonical url for that page. I just found out that when I change the question title, the url is changed immediately. The canonical url is also updated. Does it mean that as long as the page with the old canonical url redirects to the new canonical url, then search engines will update their records of the canonical url as well? Is there anything else that one can actively do to make the url change even more smoother?

  • Convert a Linksys WAG54GP2 ADSL router into Access point only to extend my Wifi range

    - by Preet Sangha
    I have a wireless lan running on my ASDL2 connection. The router (Seimens Gigaset sx763) is provided by the ISP and is generally good. However I have couple of dead spots at the far end of the house and since I have my old router sitting in the drawer I thought that I'd try to convert it into simple WAP. However downloading the manual from linksys it seems to be that the manual is from an earlier firmware, but the very first option on the very first page seems promising: Wan Mode: Router or ADSL However after this I'm a bit lost. I know that the wireless card on this box will need a mac address and it must get its address from the master router (I thought static might be best). However the again the manual is out of date I have the option of DHCP: ON or OFF or RELAY I've not even got to the more complex options yet. Question is can this device even work this way (seems like it but I cannot find any docs on it), and if so how? Edit: Having now fiddled around I'm of the opinion that this cannot be done.

  • Mouse click-focus wanders in vmPlayer 3.0 dual-monitor

    - by Gary M. Mugford
    Previously, a WinXPSP3 session running on a WinXPSP3 host computer ran perfectly fine in a dual monitor setup. No issues with vmPlayer 2.x. BEFORE updating to vmPlayer 3, the following problem cropped up. When clicking in a single monitor, you would get exactly what you expected. However, when the display was stretched across two monitors, the clicking would be to the left of the mouse cursor. The farther RIGHT you were, the farther left the click would occur. In other words, if you clicked on the system menu of a window in the upper left of a window on the left monitor, you would get the system menu. Move half a screen to your right and the click would be on an item about a quarter of the way over, rather than where you were clicking. And by going all the way to the far right of the right monitor, you could bring up a right-click menu on the far right of the LEFT monitor. I Hope I have described this properly. It's confusing, even in words. In single monitor mode, everything works perfectly fine. If, instead of using either UltraMon or DisplayFusion, you run a single desktop across both monitors (3200x1600), there are no mousing issues. Unfortunately, having two 1600x1200 monitors, that depth of 1600 makes that hack less than useable. My graphic card won't offer anything resembling 3200x1200. vmPlayer 3.0 did not alleviate the situation. The microsoft mouse drivers are up to date and so are the nVidia card drivers. Any ideas?

  • Help Prevent Carpal Tunnel Problems with Workrave

    - by Matthew Guay
    Whether for work or leisure, many of us spend entirely too much time on the computer everyday.  This puts us at risk of having or aggravating Carpal Tunnel problems, but thanks to Workrave you can help to divert these problems. Workrave helps Carpal Tunnel problems by reminding you to get away from your computer periodically.  Breaking up your computer time with movement can help alleviate many computer and office related health problems.  Workrave helps by reminding you to take short pauses after several minutes of computer use, and longer breaks after continued use.  You can also use it to keep from using the computer for too much You time in a day.  Since you can change the settings to suit you, this can be a great way to make sure you’re getting the breaks you need. Install Workrave on Windows If you’re using Workrave on Windows, download (link below) and install it with the default settings. One installation setting you may wish to change is the startup.  By default Workrave will run automatically when you start your computer; if you don’t want this, you can simply uncheck the box and proceed with the installation. Once setup is finished, you can run Workrave directly from the installer. Or you can open it from your start menu by entering “workrave” in the search box. Install Workrave in Ubuntu If you wish to use it in Ubuntu, you can install it directly from the Ubuntu Software Center.  Click the Applications menu, and select Ubuntu Software Center. Enter “workrave” into the search box in the top right corner of the Software Center, and it will automatically find it.  Click the arrow to proceed to Workrave’s page. This will give you information about Workrave; simply click Install to install Workrave on your system. Enter your password when prompted. Workrave will automatically download and install.   When finished, you can find Workrave in your Applications menu under Universal Access. Using Workrave Workrave by default shows a small counter on your desktop, showing the length of time until your next Micro break (30 second break), Rest break (10 minute break), and max amount of computer usage for the day. When it’s time for a micro break, Workrave will popup a reminder on your desktop. If you continue working, it will disappear at the end of the timer.  If you stop, it will start a micro-break which will freeze most on-screen activities until the timer is over.  You can click Skip or Postpone if you do not want to take a break right then. After an hour of work, Workrave will give you a 10 minute rest break.  During this it will show you some exercises that can help eliminate eyestrain, muscle tension, and other problems from prolonged computer usage.  You can click through the exercises, or can skip or postpone the break if you wish.   Preferences You can change your Workrave preferences by right-clicking on its icon in your system tray and selecting Preferences. Here you can customize the time between your breaks, and the length of your breaks.  You can also change your daily computer usage limit, and can even turn off the postpone and skip buttons on notifications if you want to make sure you follow Workrave and take your rests! From the context menu, you can also choose Statistics.  This gives you an overview of how many breaks, prompts, and more were shown on a given day.  It also shows a total Overdue time, which is the total length of the breaks you skipped or postponed.  You can view your Workrave history as well by simply selecting a date on the calendar.   Additionally, the Activity tab in the Statics pane shows more info about your computer usage, including total mouse movement, mouse button clicks, and keystrokes. Conclusion Whether you’re suffering with Carpal Tunnel or trying to prevent it, Workrave is a great solution to help remind you to get away from your computer periodically and rest.  Of course, since you can simply postpone or skip the prompts, you’ve still got to make an effort to help your own health.  But it does give you a great way to remind yourself to get away from the computer, and especially for geeks, this may be something that we really need!

  • Bash mine script, please

    - by HomelyPoet
    The script, in and of its self, is fairly self-explanatory. Use if You so desire; any and all criticism wouldst be appreciated, as wouldst any suggestions for improvement. First iteration was writ upon OS X 10.5.8 Leopard, current iteration was run upon OS X 10.6.4 Snow Leopard with Safari 5.0.2 (6533.18.5). Also, any illumination as to why the first line ' if [ -f ] ' works, but ' if [ -f ~/Library/Safari/LocalStorage/*.localstorage ] ' generates an error?

  • Happy 3rd Birthday SilverlightCream!

    - by Dave Campbell
    Happy 3rd Birthday!     Yesterday (May 16) was the 'Birthday' of SilverlightCream, which started just after MIX in 2007 with a post "Interesting Silverlight posts today: Silverlight Control & Silverlight Pad". Too many good posts flying around led me to want to archive them, particularly since I was being aggregated at a new site Silverlight.net, and I could give some of that 'reach' to the community. Saturday's post was number 862, and as of that post, there were 5697 blog posts archived in the database all tagged up and searchable at SilverlightCream.com using the search page. The search needs to be better, and that's another discussion, but it does work. The blog didn't begin life as the SilverlightCream blog, as is obvious from the name, but once I realized people were following it closely, I've tried to keep the signal-to-noise ratio very high. I even secured another blog for when I just want to rant about something to keep that stuff out of this one :) If you've been around since MIX07 days you've heard all this, but after talking to some people at MIX10 I realized not everyone knows all the ways the information is presented, so I figured doing a post like this once a year probably isn't a bad idea :) I scrounge through an ever-growing list of blogs (right now sitting at 505) looking for good stuff. I try to spin through the list every day, but with the list growing that large, it's getting tough. I usually use it as a background task while working or watching TV. If I just sit and go through the blogs it takes about an hour. The list is long enough now that from time to time, I'll only get partway through it and have 10 to 13 entries, so I'll just stop there and go on the next day... I don't like to have more than 15 in any single post. It's all pattern recognition as in "seen that", "seen that", "that's new", etc... so if you're a blogger, look at a heading below for some comments about blogging from my perspective. When I see something new, I make sure you're not pulling a 'Mike Taulty' on me and dumping 6 or 8 new posts in one day :), and I tag the ones I want to review. If there's not a lot going on, I may just push the posts as I come across them. Some days there may be 60 posts in that 'to review' list! Some are non-Silverlight, some are essentially duplicates of others, some are demos, ads, new releases of something, session materials, etc. I push lots of material into a database at WynApse.com, and the "Tagged Posts" menu on the left sidebar there takes you to a tag cloud of (at this very moment) "9224 articles tagged 13915 different ways using 459 unique tags". There are links in there on Gibson guitars, Jazz Guitar instructional stuff, Ford F-250 links, and tons of technical and non-technical stuff I've been aggregating for about 5 years now. So when I decide to blog (or shoutout) something, I first push it into the database at WynApse.com. Then I tag it all up and push it into the database at SilverlightCream.com. Then it gets pushed to @SilverlightNews. For a little over a year now, we're tracking unique IP hits on posts launched from either the blog post or from one of the SilverlightCream.com pages, and the posts with top hits from unique IP addresses in the last 7 days are displayed in a 'Skim' page at SilverlightCream... and that page needs work as well. The Skim page and tracking was the brainchild of my buddy Michael Washington. What I blog/shoutout After some time doing posts, I decided there were things that probably have no need to be searchable, but are good information, so I post those as 'Shoutouts'. Eventually I also decided the Shoutouts should get posted to @SilverlightNews, and that's now taking place. Notes to bloggers Remember I said spinning throught the Big List-o-BlogsTM is pattern recognition... that means I don't spend a lot of time on any individual blog deciding if it has new content. If you're familiar with the term 'Above the Fold', then you're probably ok. If I have to scroll the page to see if there's something new, or wade through some maze of menus, I'm probably going to miss new stuff. Likewise if you only show the latest on the front page and make it a puzzle to find the rest of them, or if you make the titles and initial graphics almost identical to the previous article, I'll miss it. Another thing is name/brand-recognition. Far be it for me (WynApse) to comment on someone blogging with a pseudonym, but if you want to get get some recognition, you are going to want your name to be available somewhere. I can think right off the top of my head of a couple good blogs that I have no idea of the individuals' real names. I can pull that off a bit because I've been around so long almost everyone knows who I am, but if you're new to the blog-o-sphere, being able to be name-recognized is as important as getting your brand out there. Kick my tires Finally, stuff happens... I may hit the wrong key and delete your blog, or a post might slip past me and I not realize it's new because of the naming, and never blog it. If you think I missed something, send me an email or use the submit page at SilverlightCream.com. Some bloggers have figured out that if they submit (one way or another) to me, their posts will go out next. I try to honor anyone that takes the time to submit with a quicker 'Cream posting. Thanks! Finally, thanks to everyone that contributes to the community as a whole... the blogs, the videos, and the presentations. A special thanks to everyone that reads SilverlightCream, or follows @WynApse or @SilverlightNews. Keep it all coming, and... Stay in the 'Light

  • Text editor with coloring to highlight "non-parameters" in conf files?

    - by Zabba
    Some .conf files have a lot of comments and parameters in them like so: # WINS Server - Tells the NMBD components of Samba to be a WINS Client # Note: Samba can be either a WINS Server, or a WINS Client, but NOT both ; wins server = w.x.y.z # This will prevent nmbd to search for NetBIOS names through DNS. dns proxy = no ..... It gets difficult to look for only the parameters among the plethora of comments, so, is there some text editor that can highlight the comments in dark grey so that the real parameters stand out?

  • What are the benefits and drawback of documentation vs tutorials vs video tutorials [closed]

    - by Cat
    Which types of learning resources do you find the most helpful, for which kinds of learning and/or perhaps at specific times? Some examples of types of learning you could consider: When starting to integrate a new SDK inside an existing codebase When learning a new framework without having to integrate legacy code When digging deeper into an already-used SDK that you may not know very well yet For example - (video) tutorials are usually very easy to follow and tells a story from beginning to end to get results, but will nearly always assume starting from scratch or a previous tutorial. Therefore such a resource is useful for quick learning if you don't have legacy code around, but less so if you have to search for the best-fit to the code you already have. SDK Documentation on the other hand is well-structured but does not tell a story. It is more difficult to get to a specific larger result with documentation alone, but it is a better fit when you do have legacy code around and are searching for perhaps non-obvious ways of employing the SDK or library. Are there other forms of resources that you find useful, such as interactive training?

  • HTML Javascript Hidden Object or Photo Hunt Game

    - by PeteT
    Is anyone aware of any example photo hunt/hidden object games either in HTML and Javascript or flash if necessary? I am having trouble finding one, I may be using the wrong words to search. Photo hunt being like the wheres wally/waldo books where you look for wally in a complex image until you find him. So if it were played on screen you would press the location of wally and it would either be correct or wrong, possibly timed. I am hoping to find one where you can just load in your own photos and specify some co-ordinates that match where the hidden object is. A spot the difference example may be useful as a starting point but I haven't found an example of either that is web based yet.
