  • Oracle for the SQL Server books?

    - by MattK
    I am looking for a reference for a SQL Server DBA who has to come up to speed on basic Oracle 11 DBA tasks: backup, recovery, user administration, etc. There seems to be some material on the web for the reverse: Oracle - SQL Server, but the only potentially useful resource I have found in a few searches is yet to be published: http://www.amazon.com/Oracle-Database-Administration-Microsoft-Osborne/dp/0071744312 Can anyone provide references to something currently available?

    - by EugeneP
    What tools and standards do you use to describe your project, database, modules, classes, their interaction for programmers, let's say after the project is finished. Do you use UML?

Are there specific tools that simplify this documentation process & compilation of neccessary docs. If there are good books on project documenting process, please give me links to Amazon.

  • Advantages of SQLServer vs. MySQL for C#/.NET4 Cloud Applications

    - by Ed Eichman
    I am considering building several C#/.NET4 applications all using a central, cloud based database. In addition, several LAMP (MySQL) web shops will be accessing the cloud DB. MySQL is the database that I'm most familiar with, and my default selection for the cloud DB would be MySQL on Amazon or Joyent. However, I was wondering what development "extras" are available for SQLServer in VisualStudio 2010 that are not available for MySQL. Are there any "killer features" that should make me consider SQLServer instead of MySQL?

  • Is there any NHibernate book?

    - by Przemek
    Taking into consideration that NHibernate has been available for some time I thought that there would be a book available already. A search on amazon turned out just one that apparently has been delayed (Manning). Meanwhile, it looks that there seems to be coming many books on Microsoft Entity Framework. Is there any significance in that?

    - by Randy
    Our company would like to mirror our Maven 2 Repository inside of the Amazon network. What software should one use to do this? We have looked into a Wagon-S3 but that sort of functionality is not desirable... we want the artifacts to already be present when we are ready for a build.

  • Differences between Zend Framework 1.8 and 1.10

    - by Pat
    I want to start learning Zend Framework. My only concern is that the most recent ZF book on Amazon with good reviews teaches version 1.8 of the framework, which is now about a year old. Do you think it would be a good idea to still pick up that book or is it too old now?

  • Moving .JS files to a CDN: How to manage AJAX requests?

    - by pagewil
    I am thinking of moving my static .JS files to a CDN such as Amazon S3 for performance reasons. As my PHP files and mySQL DB remain on my primary hosting domain what is the best way to manage my JS AJAX requests if they are now cross domain? Currently they look like this within my .JS file (with relative paths): $.ajax({ type: "POST", url: "/myNearbyPhpFile.php", data: {data:someData}, success: function($r){} });

  • Unlimited Online File Storage

    - by AmeL
    Well, I would like to build a file hosting website just like other already did, but it is going to be something different by adding search engine, allowing download and upload in full speed for any user, and so on. Unfortunately the web hosting plans, which declared to support UNLIMITED SPACE rarely allows me to host files on those space. So what I need is the unlimited file storage service which could host all of my users' files. I found Amazon S3, already provides such service, but could anybody recommends me for other better ?

  • Strange DNS issue with internal Windows DNS

    - by Brady
    I've encountered a strange issue with our internal Windows DNS infrastructure. We have a website hosted on Amazon EC2 with the DNS running on Amazon Route 53. In the publicly facing DNS we have the wildcard record setup as an A record Alias pointing to an AWS Elastic Load Balancer sitting in front of our EC2 instances. For those who are not aware, the A record Alias behaves like a CNAME record, however no extra lookup is required on the client side (See http://docs.amazonwebservices.com/Route53/latest/DeveloperGuide/CreatingAliasRRSets.html for more information). We have a secondary domain that has the www subdomain as a CNAME pointing to a subdomain on the primary domain, which resolves against the wildcard entry. For example the subdomain www.secondary.com is a CNAME to sub1.primary.com, but there is no explicit entry for sub1.primary.com, so it resolves to wildcard record. This setup work without issue publicly. The issue comes in our internal DNS at our corporate office where we use the same primary domain for some internal only facing sites. In this setup we have two Active Directory DNS servers with one Server 2003 and one Server 2008 R2 instance. The zone is an AD integrated zone, but it is not the AD domain. In the internal DNS we have the wildcard record pointing to a third external domain, that is also hosted on Route 53 with an A record Alias pointing to the same ELB instance. For example, *.primary.com is a CNAME to tertiary.com, so in effect you have www.secondary.com as a CNAME to *.primary.com, which is a CNAME to tertiary.com. In this setup, attempting to resolve www.secondary.com will fail. Clearing the cache on the Server 2003 instance will allow it to resolve once, but subsequent attempts will fail. It fails even with a clean cache against the 2008 R2 server. It seems that only Windows clients are affected. A Mac running OSX Mountain Lion does not experience this issue. I'm even able to replicate the issue using nslookup. Against the 2003 server, with a freshly cleaned cache, I recieve the appropriate response from www.secondary.com: Non-authoritative answer: Name: subdomain.primary.com Address: x.x.x.x (Public IP) Aliases: www.secondary.com Subsequent checks simply return: Non-authoritative answer: Name: www.secondary.com If you set the type to CNAME you get the appropriate responses all the time. www.secondary.com gives you: Non-authoritative answer: www.secondary.com canonical name = subdomain.primary.com And subdomain.primary.com gives you: subdomain.primary.com canonical name = tertiary.com And setting type back to A gives you the appropriate response for tertiary.com: Non-authoritative answer: Name: tertiary.com Address: x.x.x.x (Public IP) Against the 2008 R2 server things are a little different. Even with a clean cache, www.secondary.com returns just: Non-authoritative answer: Name: www.secondary.com The CNAME records are returned appropriately. www.secondary.com returns: Non-authoritative answer: www.secondary.com canonical name = subdomain.primary.com And subdomain.primary.com gives you: subdomain.primary.com canonical name = tertiary.com tertiary.com internet address = x.x.x.x (Public IP) tertiary.com AAAA IPv6 address = x::x (Public IPv6) And setting type back to A gives you the appropriate response for tertiary.com: Non-authoritative answer: Name: tertiary.com Address: x.x.x.x (Public IP) Requests directly against subdomain.primary.com work correctly.

  • Remmina remoteapp over RDP

    - by ZombieDev
    I was wondering how to use remmina to open applications on a Windows machine over rdp using remoteapp (or seamless or whatever it's actually called). I've already used Kim Knight's RemoteApp Tool to set up remoteapp on a Windows 7 machine and I can connect and run remote apps fine from another windows box. Allegedly FreeRDP (which Remmina uses for its RDP Plugin) has support for remoteapp. I'm not sure how to make use of it though. I can't find any examples of people actually doing this online but there is a launchpad bug about the clipboard not working in remote apps, from which I can infer that there is some way to run remote apps. I've tried many combinations of settings for Client, Startup Program and Startup Path in the Advanced tab when configuring an RDP connection in Remmina, but I can't make it work. I can connect to Windows boxes with RDP just fine, just not running a remoteapp.

    - by PDeb
    I get the following error while openning a .xls file in Libreoffice Calc, Ubuntu 12.04 [LibreOffice 3.5.5.2; Build ID: 350m 1 (Build:2)] To overcome this I checked the LibreOffice Security Level to Low under Macro Security (from Tools---- Options--- Security tab.

Even I ran the following commands to install latest Java run time environments from terminal window sudo apt-get install openjdk-7-jre icedtea-7-plugin But still I get the same Basicruntime error (details as in the title bar). This particular file opens perfectly in Microsoft Excel 2007, in Win XP Professional.

  • Configuring Novel iPrint client on ubuntu 13.10

    - by Mahdi Sadeghi
    Recently I have struggled a lot to make Novel iPrint client to work on my laptop. I need it to use Follow Me printers in our university(you can take your print form any printer). Using this tutorial from Novel, I tried to convert the rpm package and install it on Ubuntu 13.04 & 13.10. The post install script from installing generated deb package had a typo which I saw in post install messages and I fixed that. Now I have the client running. To see the client UI I installed cinnamon desktop(because unity does not have system tray and old solutions did'nt work to whitelist Novel clinet). I have iPrint plugin installed on firefox as well(I copied the shared object files to plugin directories). I try installing printers from provided ipp URL(which lists available printers on the server) with no success. After clicking the printer name I see this: I have various errors: Formerly firefox used to asked my network username/password for installing SSL printer but now it returns this: iPrint Printer - The printer is currently not available. However I can install non-SSL version but the printer location is either empty or points to: file:///dev/null even if I change it to the exact address which I see on working machines still it prints nothing. I have tried the novel command line tool, iprntcmd to print. It is being installed at: /opt/novell/iprint/bin/ msadeghi@werkstatt:/opt/novell/iprint/bin$ ./iprntcmd --addprinter ipp://iprint.rz.hs-offenburg.de/ipp/Follow-me\ -\ IPP iprntcmd v05.04.00 Adding printer ipp://iprint.rz.hs-offenburg.de/ipp/Follow-me - IPP. Added printer ipp://iprint.rz.hs-offenburg.de/ipp/Follow-me - IPP successfully. It adds the printer with empty location and again no print. What I found interesting is the log file at ~/.iprint/errors.txt with strange errors which I hope somebody here can understand. When I try to install the SSL printer I receive these logs(note that HP is my local printer and has nothing to do with iprint): Thu Oct 31 11:02:03 2013 Trace Info: iprint.c, line 6690 Group Info: IPRINT-lib Error Code: 4096 (0x1000) User ID: 1000 Error Msg: iPrint Lib - Bad URI type supplied (not IPP:, HTTP:, or HTTPS:).

It worked for me on linux mint maya with my old laptop as well. Is there anybody out there who can help me to solve these problems? I am really disappointed with Novell and our university support. PS. I had the same problemwith 13.04. No matter if I am within the network or I connect with VPN, I have the same issues.

  • Eclipse Check for Updates issue

    - by Nicholas Ryan Bowers
    I install Eclipse from the Software Center so it links up and will be updated with the rest of my software. Because I am developing for Android, however, I have to install the ADT Plugin within Eclipse by going to Help Install new software (or something to that effect). Now, I do understand that I can update Eclipse through the actual Ubuntu software center/system, but in order to update plugins and extensions within Eclipse, I have to go to Help Check for Updates (which then scans all plugins for updates). The only issue, is that when I installed through the software center, the owner became root, and whenever I run it without root, I'm not able to update - I get the error message "Insufficient access privileges to apply this update." When I run it as root, all of my plugins disappear, because I guess I installed them as myself, not as root. I tried to install the plugins as root, but the Install New Software choice would not work. Ubuntu 12.04 and Eclipse 3.7.2-1

  • jQuery 1.4 Opacity and IE Filters

    - by Rick Strahl
    Ran into a small problem today with my client side jQuery library after switching to jQuery 1.4. I ran into a problem with a shadow plugin that I use to provide drop shadows for absolute elements – for Mozilla WebKit browsers the –moz-box-shadow and –webkit-box-shadow CSS attributes are used but for IE a manual element is created to provide the shadow that underlays the original element along with a blur filter to provide the fuzziness in the shadow. Some of the key pieces are: var vis = el.is(":visible"); if (!vis) el.show(); // must be visible to get .position var pos = el.position(); if (typeof shEl.style.filter == "string") sh.css("filter", 'progid:DXImageTransform.Microsoft.Blur(makeShadow=true, pixelradius=3, shadowOpacity=' + opt.opacity.toString() + ')'); sh.show() .css({ position: "absolute", width: el.outerWidth(), height: el.outerHeight(), opacity: opt.opacity, background: opt.color, left: pos.left + opt.offset, top: pos.top + opt.offset }); This has always worked in previous versions of jQuery, but with 1.4 the original filter no longer works. It appears that applying the opacity after the original filter wipes out the original filter. IOW, the opacity filter is not applied incrementally, but absolutely which is a real bummer. Luckily the workaround is relatively easy by just switching the order in which the opacity and filter are applied. If I apply the blur after the opacity I get my correct behavior back with both opacity: sh.show() .css({ position: "absolute", width: el.outerWidth(), height: el.outerHeight(), opacity: opt.opacity, background: opt.color, left: pos.left + opt.offset, top: pos.top + opt.offset }); if (typeof shEl.style.filter == "string") sh.css("filter", 'progid:DXImageTransform.Microsoft.Blur(makeShadow=true, pixelradius=3, shadowOpacity=' + opt.opacity.toString() + ')'); While this works this still causes problems in other areas where opacity is implicitly set in code such as for fade operations or in the case of my shadow component the style/property watcher that keeps the shadow and main object linked. Both of these may set the opacity explicitly and that is still broken as it will effectively kill the blur filter. This seems like a really strange design decision by the jQuery team, since clearly the jquery css function does the right thing for setting filters. Internally however, the opacity setting doesn’t use .css instead hardcoding the filter which given jQuery’s usual flexibility and smart code seems really inappropriate. The following is from jQuery.js 1.4: var style = elem.style || elem, set = value !== undefined; // IE uses filters for opacity if ( !jQuery.support.opacity && name === "opacity" ) { if ( set ) { // IE has trouble with opacity if it does not have layout // Force it by setting the zoom level style.zoom = 1; // Set the alpha filter to set the opacity var opacity = parseInt( value, 10 ) + "" === "NaN" ? "" : "alpha(opacity=" + value * 100 + ")"; var filter = style.filter || jQuery.curCSS( elem, "filter" ) || ""; style.filter = ralpha.test(filter) ? filter.replace(ralpha, opacity) : opacity; } return style.filter && style.filter.indexOf("opacity=") >= 0 ? (parseFloat( ropacity.exec(style.filter)[1] ) / 100) + "": ""; } You can see here that the style is explicitly set in code rather than relying on $.css() to assign the value resulting in the old filter getting wiped out. jQuery 1.32 looks a little different: // IE uses filters for opacity if ( !jQuery.support.opacity && name == "opacity" ) { if ( set ) { // IE has trouble with opacity if it does not have layout // Force it by setting the zoom level elem.zoom = 1; // Set the alpha filter to set the opacity elem.filter = (elem.filter || "").replace( /alpha\([^)]*\)/, "" ) + (parseInt( value ) + '' == "NaN" ? "" : "alpha(opacity=" + value * 100 + ")"); } return elem.filter && elem.filter.indexOf("opacity=") >= 0 ? (parseFloat( elem.filter.match(/opacity=([^)]*)/)[1] ) / 100) + '': ""; } Offhand I’m not sure why the latter works better since it too is assigning the filter. However, when checking with the IE script debugger I can see that there are actually a couple of filter tags assigned when using jQuery 1.32 but only one when I use jQuery 1.4. Note also that the jQuery 1.3 compatibility plugin for jQUery 1.4 doesn’t address this issue either.

  • Ubuntu 12.04 installation problem

    - by LittleLego
    Okay, at the beginning of the installation, it went well. My laptop is connected to power source, the internet, I have also checked the boxes "install updates while installation", "install third party plugin". After inputting location, keyboard layout info and user's details and password, the installation took place. But after 3/4 of the installation, it stopped, right above the progress bar, it displayed "installing system", I clicked on the arrow below it, the terminal-like screen also stopped carrying out the process. I then clicked on the "Skip" button, nothing happens. I thought it was the problem of my laptop, then I did another fresh installation, same thing happened. The terminal-like screen was showing some different words. But it's not an error message, just some installation info. Does anyone have valuable solution to this problem?

  • Bluetooth DUN Tethering fails

    - by tacone
    I have an HTC Desire HD, with Android Froyo (2.2) and PDANet installed. I am using Ubuntu 10.10. I cannot tether it over Bluetooth either with Network Manager or BlueMan. (note, I installed Blueman only after failing with NetWork manager, and I even tried the last version from the PPA). With both my device is discovered, paired, setup. But connecting always fail. Network manager says it cannot get the details of my device Blueman says Connection Refused (111) Here are some relevant entries from syslog.
