  • Java ORM related question - SQL Vs Google DB (Big Table?) GAE

    - by StackerFlow
    I was wondering about the following two options when one is not using SQL tables but ORM based DBs (Example - when you are using GAE) Would the second option be less efficient? Requirement: There is an object. The object has a collection of similar items. I need to store this object. Example, say the object is a tree and it has a collection of leaves. Option 1: Traditional SQL type structure: Table for the Tree (with TreeId as the identifier for a row in the Table.) Table for the Leaves (where each leaf has a TreeId and to show the leaves of a tree, I query all leaves where the TreeId is the Id of the tree.) Here, the Tree structure DOES NOT have a field with leaves. Option 2: ORM / GAE Tables: Using the same example above, I have an object for Tree where the object has a collection (Set/List in Java/C++) of leaves. I store and retrieve the Tree together with the leaves (as the leaves are implemented as a Set in the Tree object) My question is, will the second one be less efficient that the first option? If so, why? Are there other alternatives? Thank you!

  • What is the best way to create a running integer id on the AppEngine data storage?

    - by Freed
    For various reasons, I need a unique running integer id for my entities stored on the Google AppEngine. The automatically generated key sort of has this behaviour, but it doesn't start from 1 (or 0) and doesn't guarantee that the generated integer part will come from a continuous sequence. What would be the best way to efficiently implement this on AppEngine? Is there any support from the storage system? To add to the complexity, I might need to do this over entities from different entity groups, meaning I can't just get the highest id right now and save an entity with the next id in a transaction. Might memcache be the way to go..? Edit: I havn't yet implemented this, but to clarify on the memcache idea. I know memcache is unreliable, but in practice it probably won't lose data "too often" to hurt performance. Basically, I would have a memcache entry for the last used id, update it (somehow atomically) whenever I create a new entity and use that id. In the case of memcache not having a value for this entry, I'd get the highest id so far by doing a query on my entities sorted by the id and update memcache (unless someone else had already done so). The only problem I can see with this right now would be atomicity of the operation as a whole if the save of my new entity was also part of a transaction. Thoughts..?

  • Lua not producing table of functions (IO API)

    - by ArtOfCode
    I'm working on a basic project in Lua. I've been trying to get data from files using the IO API (as defined here), but when I open a file and give it a handle, it doesn't seem to return a table of functions. The (erroneous bit of) code: local unread = fs.list("email/"..from.."/") local send = "" for _,file in ipairs(unread) do local handle = io.open(file,"r") local text = handle:read("*a") send = send .. text .. "\n" handle.close() fs.delete(file) end The fs you see on the first line is a professional filesystem wrapper round the IO API, not my work and perfectly error-free, so that's not the problem. However, when I try to read the file (handle:read()), it throws "attempt to index nil". Tracing it, it turns out that handle itself is nil. Any ideas?

  • Works on development server but it doesn't on Google App Engine (Sessions).

    - by grep
    Hi, I have this code that works just fine on the development server but when I deploy the application, the session isn't created. What am I doing wrong? HttpSession session = req.getSession(true); session.setAttribute("loggedIn", new String("true")); Edit: The sessions are enabled. What I realized now is that the _ah_SESSION variable is not being created, not even on the development server (although it works).

  • How to get warning massage when clicking close(X) button of browser with tabs in Google Crome

    - by Shantanu
    How to get a warning massage if i accidently click the close button of the chrome browser which have multiple tabs opened at that time? I am a regular user of Crome and having this problem while using it. I normally open multiple tabs inside a single browser but sometimes i accidently click the close button of browser and as soon as the button is clicked crome does't give any warning issue about multiple active tabs and close the entire window. Is the end user like me is browsing on normal crome window then he can open the websites again by checking the web history but if he is browsing inside private browser then he can't do anything(this happens with me very regularly because i normally browse in private browser). On the other hand if you accidently click the close button in mozilla which have multiple tabs open it throws a warning massage to the user and asks for his wish.

  • SQL SERVER – SHRINKFILE and TRUNCATE Log File in SQL Server 2008

    - by pinaldave
    Note: Please read the complete post before taking any actions. This blog post would discuss SHRINKFILE and TRUNCATE Log File. The script mentioned in the email received from reader contains the following questionable code: “Hi Pinal, If you could remember, I and my manager met you at TechEd in Bangalore. We just upgraded to SQL Server 2008. One of our jobs failed as it was using the following code. The error was: Msg 155, Level 15, State 1, Line 1 ‘TRUNCATE_ONLY’ is not a recognized BACKUP option. The code was: DBCC SHRINKFILE(TestDBLog, 1) BACKUP LOG TestDB WITH TRUNCATE_ONLY DBCC SHRINKFILE(TestDBLog, 1) GO I have modified that code to subsequent code and it works fine. But, are there other suggestions you have at the moment? USE [master] GO ALTER DATABASE [TestDb] SET RECOVERY SIMPLE WITH NO_WAIT DBCC SHRINKFILE(TestDbLog, 1) ALTER DATABASE [TestDb] SET RECOVERY FULL WITH NO_WAIT GO Configuration of our server and system is as follows: [Removed not relevant data]“ An email like this that suddenly pops out in early morning is alarming email. Because I am a dead, busy mind, so I had only one min to reply. I wrote down quickly the following note. (As I said, it was a single-minute email so it is not completely accurate). Here is that quick email shared with all of you. “Hi Mr. DBA [removed the name] Thanks for your email. I suggest you stop this practice. There are many issues included here, but I would list two major issues: 1) From the setting database to simple recovery, shrinking the file and once again setting in full recovery, you are in fact losing your valuable log data and will be not able to restore point in time. Not only that, you will also not able to use subsequent log files. 2) Shrinking file or database adds fragmentation. There are a lot of things you can do. First, start taking proper log backup using following command instead of truncating them and losing them frequently. BACKUP LOG [TestDb] TO  DISK = N'C:\Backup\TestDb.bak' GO Remove the code of SHRINKING the file. If you are taking proper log backups, your log file usually (again usually, special cases are excluded) do not grow very big. There are so many things to add here, but you can call me on my [phone number]. Before you call me, I suggest for accuracy you read Paul Randel‘s two posts here and here and Brent Ozar‘s Post here. Kind Regards, Pinal Dave” I guess this post is very much clear to you. Please leave your comments here. As mentioned, this is a very huge subject; I have just touched a tip of the ice-berg and have tried to point to authentic knowledge.

  • Want a headless build server for SSDT without installing Visual Studio? You’re out of luck!

    - by jamiet
    An issue that regularly seems to rear its head on my travels is that of headless build servers for SSDT. What does that mean exactly? Let me give you my interpretation of it. A SQL Server Data Tools (SSDT) project incorporates a build process that will basically parse all of the files within the project and spit out a .dacpac file. Where an organisation employs a Continuous Integration process they will likely want to automate the building of that dacpac whenever someone commits a change to the source control repository. In order to do that the organisation will use a build server (e.g. TFS, TeamCity, Jenkins) and hence that build server requires all the pre-requisite software that understands how to build an SSDT project. The simplest way to install all of those pre-requisites is to install SSDT itself however a lot of folks don’t like that approach because it installs a lot unnecessary components on there, not least Visual Studio itself. Those folks (of which i am one) are of the opinion that it should be unnecessary to install a heavyweight GUI in order to simply get a few software components required to do something that inherently doesn’t even need a GUI. The phrase “headless build server” is often used to describe a build server that doesn’t contain any heavyweight GUI tools such as Visual Studio and is a desirable state for a build server. In his blog post Headless MSBuild Support for SSDT (*.sqlproj) Projects Gert Drapers outlines the steps necessary to obtain a headless build server for SSDT: This article describes how to install the required components to build and publish SQL Server Data Tools projects (*.sqlproj) using MSBuild without installing the full SQL Server Data Tool hosted inside the Visual Studio IDE. http://sqlproj.com/index.php/2012/03/headless-msbuild-support-for-ssdt-sqlproj-projects/ Frankly however going through these steps is a royal PITA and folks like myself have longed for Microsoft to support headless build support for SSDT by providing a distributable installer that installs only the pre-requisites for building SSDT projects. Yesterday in MSDN forum thread Building a VS2013 headless build server - it's sooo hard Mike Hingley complained about this very thing and it prompted a response from Kevin Cunnane from the SSDT product team: The official recommendation from the TFS / Visual Studio team is to install the version of Visual Studio you use on the build machine. I, like many others, would rather not have to install full blown Visual Studio and so I asked: Is there any chance you'll ever support any of these scenarios: Installation of all build/deploy pre-requisites without installing the VS shell? TFS shipping with all of the pre-requisites for doing SSDT project build/deploys 3rd party build servers (e.g. TeamCity) shipping with all of the requisites for doing SSDT project build/deploys I have to say that the lack of a single installer containing all the pre-requisites for SSDT build/deploy puzzles me. Surely the DacFX installer would be a perfect vehicle for that? Kevin replied again: The answer is no for all 3 scenarios. We looked into this issue, discussed it with the Visual Studio / TFS team, and in the end agreed to go with their latest guidance which is to install Visual Studio (e.g. VS2013 Express for Web) on the build machine. This is how Visual Studio Online is doing it and it's the approach recommended for customers setting up their own TFS build servers. I would hope this is compatible with 3rd party build servers but have not verified whether this works with TeamCity etc. Note that DacFx MSI isn't a suitable release vehicle for this as we don't want to include Visual Studio/MSBuild dependencies in that package. It's meant to just include the core DacFx DLLs used by SSMS, SqlPackage.exe on the command line, etc. What this means is we won't be providing a separate MSI installer or nuget package with just the necessary build DLLs you need to run your build and tests. If someone wanted to create a script that generated a nuget package based on our DLLs and targets files, then release that somewhere on the web for easier integration with 3rd party build servers we've no problem with that. Again, here’s the link to the thread and its worth reading in its entirety if this is something that interests you. So there you have it. Microsoft will not be be providing support for headless build servers for SSDT but if someone in the community wants to go ahead and roll their own, go right ahead. @Jamiet

  • SQL – Quick Start with Admin Sections of NuoDB – Manage NuoDB Database

    - by Pinal Dave
    In the yesterday’s blog post we have seen that it is extremely easy to install the NuoDB database on your local machine. Now that the application is properly set up, let us explore NuoDB a bit more and get you familiar with the how it works and what the important areas of the NuoDB are that you should learn. As we have already installed NuoDB, now we will quickly start with two of the important areas in NuoDB: 1) Admin and 2) Explorer. In this blog post I will explore how the Admin Section of the NuoDB Console works.  In the next blog post we will learn how the Explorer Section works. Let us go to the NuoDB Console by typing the following URL in your browser: http://localhost:8080/ It will bring you to the following screen: On this screen you can see a big Start QuickStart button. Click on the button and it will bring you to following screen. On this screen you will find very important information about Domain and Database Settings. It is our habit that we do not read what is written on the screen and keep on clicking on continue without reading. While we are familiar with most wizards, we can often miss the very important message on the screen. Please note the information of Domain Settings and Database Settings from the following screen before clicking on Create Database. Domain Settings User: quickstart Password: quickstart Database Settings User: dba Password: goalie Database: test Schema: HOCKEY Once you click on the Create Database button it will immediately start creating sample database. First, it will start a Storage Manager and right after that it will start a Transaction Engine. Once the engine is up, it will Create a Schema and Sample Data. On the success of the creating the sample database it will show the following screen. Now is the time where we can explore the NuoDB Admin or NuoDB Explorer. If you click on Admin, it will first show following login screen. Enter for the username “domain” and for the password “bird”. Alternatively you can enter “quickstart”  twice for username and password.  It works as too. Once you enter into the Admin Section, on the left side you can see information about NuoDB and Admin Console and on the right side you can see the domain overview area. From this Administrative section you can do any of the following tasks: Create a view of the entire domain Add and remove databases Start and stop NuoDB Transaction Engines and Storage Managers Monitor transaction across all the NuoDB databases On the right side of the Admin Section we can see various information about a particular NuoDB domain. You can quickly view various alerts, find out information about the number of host machines that are provisioned for the domain, and see the number of databases and processes that are running in the domain. If you click on the “1 host” link you will be able to see various processes, CPU usage and other information. In the Processes Section you can see that there are two different types of processes. The first process (where you can see the floppy drive icon) represents a running Storage Manager process and the second process a running Transaction Engine process. You can click on the links for the Storage Manager and Transaction Engine to see further statistical details right down to the last byte of the data. There are various charts available for analysis as well. I think the product is quite mature and the user can add different monitor charts to the Admin section. Additionally, the Admin section is the place where you can create and manage new databases. I hope today’s tutorial gives you enough confidence that you can try out NuoDB and checkout various administrative activities with the database. I am personally impressed with their dashboard related to various counters. For more information about how the NuoDB architecture works and what a Storage Manager or Transaction Engine does, check out this short video with NuoDB CTO Seth Proctor:  In the next blog post, we will try out the Explorer section of NuoDB, which allows us to run SQL queries and write SQL code.  Meanwhile, I strongly suggest you download and install NuoDB and get yourself familiar with the product.

    How much frequently Google fetches sitemaps? I am now working with a high traffic website normally have 30 new posts per minute but currently it provides sitemaps which links to new 100 posts (3 minutes). Is this method is enough? Is bots fetch sitemaps every 3 minutes? Did need to change sitemaps to list all 5M posts(indexed sitemaps)? How this change will effect on traffic and PageRank? Is Googlebot remove URLs that previously listed on sitemaps but not now?

  • HTG Explains: How Private Browsing Works and Why It Doesn’t Offer Complete Privacy

    - by Chris Hoffman
    Private Browsing, InPrivate Browsing, Incognito Mode – it has a lot of names, but it’s the same basic feature in every browser. Private browsing offers some improved privacy, but it’s not a silver bullet that makes you completely anonymous online. Private Browsing mode changes the way your browser behaves, whether you’re using Mozilla Firefox, Google Chrome, Internet Explorer, Apple Safari, Opera or any other browser – but it doesn’t change the way anything else behaves.

  • SEOs: mobile version using AJAX: how to be properly read by SEOs?

    - by Olivier Pons
    Before anything else, I'd like to emphasize that I've already read this and this. Here's what I can do: Choice (1): create classical Web version with all products in that page - http://www.myweb.com. create mobile Web version with all products in the page and use jQuery Mobile to format all nicely. But this may be long to (load + format), and may provide bad user experience - http://m.myweb.com. Choice (2): create classical Web version with all products in that page create mobile Web version with almost nothing but a Web page showing "wait", then download all products in the page using AJAX and use jQuery Mobile to format all nicely. Showing a "wait, loading" message gives far more time to do whatever I want and may provide better user experience - http://m.myweb.com. Question: if I choose solution (2), google won't read anything on the mobile version (because all products will be downloaded in the page using AJAX), so it wont be properly read by SEOs. What / how shall I do?

  • Tracking pages with variables in GA

    - by Imran
    Recently I have updated my site, it now passes a variable on some links like so... www.mysite.com/1234/?play=true I've noticed in Google Analytics it records www.mysite.com/1234/ and www.mysite.com/1234/?play=true as two different URL's. Is there a way to merge them because they are after all just one page, It makes "Top Content" for example hard to read because of dupilicates. I've read about something called canonical link tag which may help this? My blog has this already inserted into the head but it doesnt make a difference. Any suggestions?
