  • Adding a CLI for PHP5 on live server

    - by Josua Pedersen
    I want to add command-line support for PHP5 on my server. When I run aptitude install php5-cli I get a message saying that my PHP modules/packages have unmet dependencies. Here is a list of packages that suffer from these "unmet dependencies" and needs and upgrade: php5-gd php5-curl php5-mysql php5-cgi They all depend on php5-common. Can I upgrade the packages just like aptitude suggests without causing any disruptions to the live site? Output from aptitude Reading package lists... Done Building dependency tree Reading state information... Done Reading extended state information Initialising package states... Done The following packages are BROKEN: libapache2-mod-php5 php5-cgi php5-curl php5-gd php5-mysql The following NEW packages will be installed: php5-cli The following packages will be upgraded: php5-common 1 packages upgraded, 1 newly installed, 0 to remove and 123 not upgraded.

  • RHEL 5.5 Yum Update Fails Dependency Error

    - by user65788
    I have 30 different RHEL 5.5 machines that will not update some 33 packages via Yum. Does anyone know why these packages will not install and how to correct this? Yum clean all does not fix the issue, however skip broken will allow other updates to install but I am really after a way to clear this up for good. They are stock boxes with RHEL subscription and not using any yum repositories other than Red Hat's own official repositories. They have not been updated for over a year! yum update Loaded plugins: rhnplugin, security rhel-i386-client-5 | 1.4 kB 00:00 rhel-i386-client-5/primary | 2.8 MB 00:09 rhel-i386-client-5 6607/6607

  • Ubuntu 12.04: apt-get "failed to fetch"; apt is trying to fetch via old static IP

    - by gabe
    Sample error: W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/precise-security/universe/i18n/Translation-en Unable to connect to 192.168.1.70:8118: Now this was working just fine until I changed the IP this morning. I have the server set to a static IP of 10.0.1.70 and for years it has been 192.168.1.70 - the IP apt-get is trying to use right now. I use privoxy and tor thus the 8118 port. Like I said it all worked until I changed the static IP from 192.168.1.70 to 10.0.1.70. I was forced to do so because of router issues. (Long and involved story, I didn't really want to change the IP because I know something like this would happen.) The setup for TOR/Privoxy requires that has you point Privoxy at TOR via 127.0.0.1:9050. Then point curl, etc to Privoxy via $HOME/.bashrc. Typically you would set the listen to IP for Privoxy to 127.0.0.1 but if you want it accessible to the rest of the LAN you set the IP to the server's LAN IP. Which I did a long time ago and was working fine until this morning. I have changed all instances of 192.168.1.70 to 10.0.1.70 in both /etc/privoxy/config and $HOME/.bashrc. What makes this really strange for me is that curl is working fine. I curl icanhazip.com and voila I get a new IP every 10 minutes or so. I curl CNN.com and I get the short but sweet permanently moved to www.cnn.com message I expect. Firefox works fine. Ping works fine. And I've tested all of this via Remote Desktop over my LAN. So the connection appears to be fine for everything except apt. I've also rebooted hoping that would clear 192.168.1.70 from apt. So the connection to the internet and DNS aren't an issue for these programs. And they are, as far as I can tell, using Privoxy/TOR just fine. The real irony here is that I've tried to open up Privoxy to go to Ubuntu's servers directly without going through TOR to speed up the downloads from Ubuntu (did this months ago). So somewhere that I have not been able to find, apt has stored the IP 192.168.1.70. And 192.168.1.70 is no longer valid. Thanks for the help

  • Determining URLs updated via a series of commit logs

    - by adamrubin
    I'm working on a project where I programmatically need to know when a URL has been changed by a developer, post or during deploy. The obvious answer may be to curl the URL one day, save the output, then curl and in x days then do a diff. That won't work in my case, as I'm only looking for changes the developer mande. If the site is a blog, new comments, user submitted photos, etc would make that curl diff useless. RoR example, using github. Let's assume I have access to the entire repository and all commit logs between iterations. Is there a way I could see that "/views/people/show.html.erb" was commited, then backtrack from there (maybe by inspecting routes.rb), to come up with the URL I can then hit via a browser?

  • Open Id XRDS Discovery

    - by Asciant
    I am working with Open Id, just playing around making a class to interact / auth Open Id's on my site (in PHP). I know there are a few other Libraries (like RPX), but I want to use my own (its good to keep help better understand the protocol and whether its right for me). The question I have relates to the Open Id discovery sequence. Basically I have reached the point where I am looking at using the XRDS doc to get the local identity (openid.identity) from the claimed identity (openid.claimed_id). My question is, do I have to make a cURL request to get the XRDS Location (X-XRDS-location) and then make another cURL request to get the actual XRDS doc?? It seems like with a DUMB request I only make one cURL request and get the Open Id Server, but have to make two to use the XRDS Smart method. Just doesn't seem right, can anyone else give me some info.

  • Mystery in Ruby sinatra

    - by JVK
    I have the following Sinatra code: post '/bucket' do # determine if this call is coming from filling out web form is_html = request.content_type.to_s.downcase.eql?('application/x-www-form-urlencoded') # If this is a curl call, then get the params differently unless is_html params = JSON.parse(request.env["rack.input"].read) end p params[:name] end If I call this using Curl, params has values, but when this is called via a web form, then params is nil and params[:name] has nothing. I spent several hours figuring out why it happens and asked help from other people, but no one could really find out what is going on. One thing to note is, if I comment out this line: params = JSON.parse(request.env["rack.input"].read) then params has the correct value for "web-form" posting. Actually, the goal is to get the params value if this code is being called by CURL call, so I used: params = JSON.parse(request.env["rack.input"].read) but it messed up the web-form posting. Can anyone solve this mystery?

    - by speekeazy
    Hello, Ive just started using jquery for the .load ajax functionality. When i load an external page to a specific div it loads fine. inside the external page there is an .append that .appends javascript to the head. This works on the initial load but when i use .load to load it this portion is not showing. //This is the .load for the div function loadContent(elementSelector, sourceUrl) { url = ""+sourceUrl+""; $(""+elementSelector+"").load(url); alert(url); } //This is the append in the other page that is embedded in a js var cUrl = "http://intensedebate.com/js/genericCommentWrapper2.php?acct="+idcomments_acct+"&postid="+idcomments_post_id+"&title="+idcomments_post_title+"&url="+idcomments_post_url; alert(cUrl); commentScript.type = "text/javascript"; commentScript.src = cUrl; $('head').append(commentScript);

  • Download File from Web C++ (with winsock?)

    - by Lienau
    I need to download files/read strings from a specified url in C++. I've done some research with this, cURL seems to be the most popular method. Also, I've used it before in PHP. The problem with cURL is that the lib is huge, and my file has to be small. I think you can do it with winsock, but I can't find any simple examples. If you have a simple winsock example, a light cURL/Something else, or anything that could get the job done. I would greatly appreciated. Also, I need this to work with native C++.

These enhancements are summarized in the Figure below, and detailed in the MySQL Cluster New Features whitepaper Figure 1: Next Generation Web Services, Cross Data Center Replication and Ease-of-Use Once of the key enhancements delivered in MySQL Cluster 7.2 is extensions made to the multi-threading processes of the data nodes. Multi-Threaded Data Node Extensions The MySQL Cluster 7.2 data node is now functionally divided into seven thread types: 1) Local Data Manager threads (ldm). Note – these are sometimes also called LQH threads. 2) Transaction Coordinator threads (tc) 3) Asynchronous Replication threads (rep) 4) Schema Management threads (main) 5) Network receiver threads (recv) 6) Network send threads (send) 7) IO threads Each of these thread types are discussed in more detail below. MySQL Cluster 7.2 increases the maximum number of LDM threads from 4 to 16. The LDM contains the actual data, which means that when using 16 threads the data is more heavily partitioned (this is automatic in MySQL Cluster). Each LDM thread maintains its own set of data partitions, index partitions and REDO log. The number of LDM partitions per data node is not dynamically configurable, but it is possible, however, to map more than one partition onto each LDM thread, providing flexibility in modifying the number of LDM threads. The TC domain stores the state of in-flight transactions. This means that every new transaction can easily be assigned to a new TC thread. Testing has shown that in most cases 1 TC thread per 2 LDM threads is sufficient, and in many cases even 1 TC thread per 4 LDM threads is also acceptable. Testing also demonstrated that in some instances where the workload needed to sustain very high update loads it is necessary to configure 3 to 4 TC threads per 4 LDM threads. In the previous MySQL Cluster 7.1 release, only one TC thread was available. This limit has been increased to 16 TC threads in MySQL Cluster 7.2. The TC domain also manages the Adaptive Query Localization functionality introduced in MySQL Cluster 7.2 that significantly enhanced complex query performance by pushing JOIN operations down to the data nodes. Asynchronous Replication was separated into its own thread with the release of MySQL Cluster 7.1, and has not been modified in the latest 7.2 release. To scale the number of TC threads, it was necessary to separate the Schema Management domain from the TC domain. The schema management thread has little load, so is implemented with a single thread. The Network receiver domain was bound to 1 thread in MySQL Cluster 7.1. With the increase of threads in MySQL Cluster 7.2 it is also necessary to increase the number of recv threads to 8. This enables each receive thread to service one or more sockets used to communicate with other nodes the Cluster. The Network send thread is a new thread type introduced in MySQL Cluster 7.2. Previously other threads handled the sending operations themselves, which can provide for lower latency. To achieve highest throughput however, it has been necessary to create dedicated send threads, of which 8 can be configured. It is still possible to configure MySQL Cluster 7.2 to a legacy mode that does not use any of the send threads – useful for those workloads that are most sensitive to latency. The IO Thread is the final thread type and there have been no changes to this domain in MySQL Cluster 7.2. Multiple IO threads were already available, which could be configured to either one thread per open file, or to a fixed number of IO threads that handle the IO traffic. Except when using compression on disk, the IO threads typically have a very light load. Benchmarking the Scalability Enhancements The scalability enhancements discussed above have made it possible to scale CPU usage of each data node to more than 5x of that possible in MySQL Cluster 7.1. In addition, a number of bottlenecks have been removed, making it possible to scale data node performance by even more than 5x. Figure 2: MySQL Cluster 7.2 Delivers 8.4x Higher Performance than 7.1 The flexAsynch benchmark was used to compare MySQL Cluster 7.2 performance to 7.1 across an 8-node Intel Xeon x5670-based cluster of dual socket commodity servers (6 cores each). As the results demonstrate, MySQL Cluster 7.2 delivers over 8x higher performance per data nodes than MySQL Cluster 7.1. More details of this and other benchmarks will be published in a new whitepaper – coming soon, so stay tuned! In a following blog post, I’ll provide recommendations on optimum thread configurations for different types of server processor. You can also learn more from the Best Practices Guide to Optimizing Performance of MySQL Cluster Conclusion MySQL Cluster has achieved a range of impressive benchmark results, and set in context with the previous 7.1 release, is able to deliver over 8x higher performance per node. As a result, the multi-threaded data node extensions not only serve to increase performance of MySQL Cluster, they also enable users to achieve significantly improved levels of utilization from current and future generations of massively multi-core, multi-thread processor designs.

  • BI Applications overview

    - by sv744
    Welcome to Oracle BI applications blog! This blog will talk about various features, general roadmap, description of functionality and implementation steps related to Oracle BI applications. In the first post we start with an overview of the BI apps and will delve deeper into some of the topics below in the upcoming weeks and months. If there are other topics you would like us to talk about, pl feel free to provide feedback on that. The Oracle BI applications are a set of pre-built applications that enable pervasive BI by providing role-based insight for each functional area, including sales, service, marketing, contact center, finance, supplier/supply chain, HR/workforce, and executive management. For example, Sales Analytics includes role-based applications for sales executives, sales management, as well as front-line sales reps, each of whom have different needs. The applications integrate and transform data from a range of enterprise sources—including Siebel, Oracle, PeopleSoft, SAP, and others—into actionable intelligence for each business function and user role. This blog  starts with the key benefits and characteristics of Oracle BI applications. In a series of subsequent blogs, each of these points will be explained in detail. Why BI apps? Demonstrate the value of BI to a business user, show reports / dashboards / model that can answer their business questions as part of the sales cycle. Demonstrate technical feasibility of BI project and significantly lower risk and improve success Build Vs Buy benefit Don’t have to start with a blank sheet of paper. Help consolidate disparate systems Data integration in M&A situations Insulate BI consumers from changes in the OLTP Present OLTP data and highlight issues of poor data / missing data – and improve data quality and accuracy Prebuilt Integrations BI apps support prebuilt integrations against leading ERP sources: Fusion Applications, E- Business Suite, Peoplesoft, JD Edwards, Siebel, SAP Co-developed with inputs from functional experts in BI and Applications teams. Out of the box dimensional model to source model mappings Multi source and Multi Instance support Rich Data Model    BI apps have a very rich dimensionsal data model built over 10 years that incorporates best practises from BI modeling perspective as well as reflect the source system complexities  Thanks for reading a long post, and be on the lookout for future posts.  We will look forward to your valuable feedback on these topics as well as suggestions on what other topics would you like us to cover. I Conformed dimensional model across all business subject areas allows cross functional reporting, e.g. customer / supplier 360 Over 360 fact tables across 7 product areas CRM – 145, SCM – 47, Financials – 28, Procurement – 20, HCM – 27, Projects – 18, Campus Solutions – 21, PLM - 56 Supported by 300 physical dimensions Support for extensive calendars; Gregorian, enterprise and ledger based Conformed data model and metrics for real time vs warehouse based reporting  Multi-tenant enabled Extensive BI related transformations BI apps ETL and data integration support various transformations required for dimensional models and reporting requirements. All these have been distilled into common patterns and abstracted logic which can be readily reused across different modules Slowly Changing Dimension support Hierarchy flattening support Row / Column Hybrid Hierarchy Flattening As Is vs. As Was hierarchy support Currency Conversion :-  Support for 3 corporate, CRM, ledger and transaction currencies UOM conversion Internationalization / Localization Dynamic Data translations Code standardization (Domains) Historical Snapshots Cycle and process lifecycle computations Balance Facts Equalization of GL accounting chartfields/segments Standardized values for categorizing GL accounts Reconciliation between GL and subledgers to track accounted/transferred/posted transactions to GL Materialization of data only available through costly and complex APIs e.g. Fusion Payroll, EBS / Fusion Accruals Complex event Interpretation of source data – E.g. o    What constitutes a transfer o    Deriving supervisors via position hierarchy o    Deriving primary assignment in PSFT o    Categorizing and transposition to measures of Payroll Balances to specific metrics to support side by side comparison of measures of for example Fixed Salary, Variable Salary, Tax, Bonus, Overtime Payments. o    Counting of Events – E.g. converting events to fact counters so that for example the number of hires can easily be added up and compared alongside the total transfers and terminations. Multi pass processing of multiple sources e.g. headcount, salary, promotion, performance to allow side to side comparison. Adding value to data to aid analysis through banding, additional domain classifications and groupings to allow higher level analytical reporting and data discovery Calculation of complex measures examples: o    COGs, DSO, DPO, Inventory turns  etc o    Transfers within a Hierarchy or out of / into a hierarchy relative to view point in hierarchy. Configurability and Extensibility support  BI apps offer support for extensibility for various entities as automated extensibility or part of extension methodology Key Flex fields and Descriptive Flex support  Extensible attribute support (JDE)  Conformed Domains ETL Architecture BI apps offer a modular adapter architecture which allows support of multiple product lines into a single conformed model Multi Source Multi Technology Orchestration – creates load plan taking into account task dependencies and customers deployment to generate a plan based on a customers of multiple complex etl tasks Plan optimization allowing parallel ETL tasks Oracle: Bit map indexes and partition management High availability support    Follow the sun support. TCO BI apps support several utilities / capabilities that help with overall total cost of ownership and ensure a rapid implementation Improved cost of ownership – lower cost to deploy On-going support for new versions of the source application Task based setups flows Data Lineage Functional setup performed in Web UI by Functional person Configuration Test to Production support Security BI apps support both data and object security enabling implementations to quickly configure the application as per the reporting security needs Fine grain object security at report / dashboard and presentation catalog level Data Security integration with source systems  Extensible to support external data security rules Extensive Set of KPIs Over 7000 base and derived metrics across all modules Time series calculations (YoY, % growth etc) Common Currency and UOM reporting Cross subject area KPIs (analyzing HR vs GL data, drill from GL to AP/AR, etc) Prebuilt reports and dashboards 3000+ prebuilt reports supporting a large number of industries Hundreds of role based dashboards Dynamic currency conversion at dashboard level Highly tuned Performance The BI apps have been tuned over the years for both a very performant ETL and dashboard performance. The applications use best practises and advanced database features to enable the best possible performance. Optimized data model for BI and analytic queries Prebuilt aggregates& the ability for customers to create their own aggregates easily on warehouse facts allows for scalable end user performance Incremental extracts and loads Incremental Aggregate build Automatic table index and statistics management Parallel ETL loads Source system deletes handling Low latency extract with Golden Gate Micro ETL support Bitmap Indexes Partitioning support Modularized deployment, start small and add other subject areas seamlessly Source Specfic Staging and Real Time Schema Support for source specific operational reporting schema for EBS, PSFT, Siebel and JDE Application Integrations The BI apps also allow for integration with source systems as well as other applications that provide value add through BI and enable BI consumption during operational decision making Embedded dashboards for Fusion, EBS and Siebel applications Action Link support Marketing Segmentation Sales Predictor Dashboard Territory Management External Integrations The BI apps data integration choices include support for loading extenral data External data enrichment choices : UNSPSC, Item class etc. Extensible Spend Classification Broad Deployment Choices Exalytics support Databases :  Oracle, Exadata, Teradata, DB2, MSSQL ETL tool of choice : ODI (coming), Informatica Extensible and Customizable Extensible architecture and Methodology to add custom and external content Upgradable across releases

  • Why C++ people loves multithreading when it comes to performances?

    - by user1849534
    I have a question, it's about why programmers seems to love concurrency and multi-threaded programs in general. I'm considering 2 main approach here: an async approach basically based on signals, or just an async approach as called by many papers and languages like the new C# 5.0 for example, and a "companion thread" that maanges the policy of your pipeline a concurrent approach or multi-threading approach I will just say that I'm thinking about the hardware here and the worst case scenario, and I have tested this 2 paradigms myself, the async paradigm is a winner at the point that I don't get why people 90% of the time talk about concurrency when they wont to speed up things or make a good use of their resources. I have tested multi-threaded programs and async program on an old machine with an Intel quad-core that doesn't offer a memory controller inside the CPU, the memory is managed entirely by the motherboard, well in this case performances are horrible with a multi-threaded application, even a relatively low number of threads like 3-4-5 can be a problem, the application is unresponsive and is just slow and unpleasant. A good async approach is, on the other hand, probably not faster but it's not worst either, my application just waits for the result and doesn't hangs, it's responsive and there is a much better scaling going on. I have also discovered that a context change in the threading world it's not that cheap in real world scenario, it's infact quite expensive especially when you have more than 2 threads that need to cycle and swap among each other to be computed. On modern CPUs the situation it's not really that different, the memory controller it's integrated but my point is that an x86 CPUs is basically a serial machine and the memory controller works the same way as with the old machine with an external memory controller on the motherboard. The context switch is still a relevant cost in my application and the fact that the memory controller it's integrated or that the newer CPU have more than 2 core it's not bargain for me. For what i have experienced the concurrent approach is good in theory but not that good in practice, with the memory model imposed by the hardware, it's hard to make a good use of this paradigm, also it introduces a lot of issues ranging from the use of my data structures to the join of multiple threads. Also both paradigms do not offer any security abut when the task or the job will be done in a certain point in time, making them really similar from a functional point of view. According to the X86 memory model, why the majority of people suggest to use concurrency with C++ and not just an async aproach ? Also why not considering the worst case scenario of a computer where the context switch is probably more expensive than the computation itself ?

  • Python requests SSL version

    - by Aaron Schif
    I am using the python requests module on Ubuntu 13.04. I keep getting the error: requests.exceptions.SSLError: [Errno 1] _ssl.c:504: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure When I use curl, it fails by default but succeeds with the -3 option. curl https://username:Password@helloworldurl -3 This leads me to believe that it is the SSL version, which I found may be badly supported on ubuntu while searching the error. Sooo. How do I change or check the SSL version using python preferably with requests. Note: the url is private and cannot be given out. Sorry.

  • Apache: DoS with mod_deflate & range requests, tomcat also? [migrated]

    - by VextoR
    I know that apache has a security bug http://seclists.org/fulldisclosure/2011/Aug/175 So if you do this command: curl -I -H "Range: bytes=0-1,0-2" -s www.yandex.ru/robots.txt it says HTTP/1.1 206 Partial Content it means, the problem is exist. But the fact is, that for apache tomcat (our server) curl says 206 Partial Content as well. So we need to fix it. I found solution for apache HTTP (.htaccess, mod_headers) but not for tomcat. I'm very newbie for servers things, so can't understand most, so please help

  • MySQL Master-Master w/ multiple read slave cost effective setup in AWS

    - by Ross
    I've been evaluating Amazon Web Services RDS for MySQL and costing out potential scenarios involving a simple multi-AZ deployment read/write setup vs. a multi-AZ deployment mysql master (hot-standby) with additional read-only slaves. the issue I'm trying to cost-optimize includes their reserved instance vs on-demand instances. Situation 1: purchase reserved multi-az setup for Extra-large-hi-mem(17GB RAM) instance for $5200/yr and have my application query the master all the time. the problem is, if I don't need all the resources of the (17GB RAM) all the time and therefore, especially not a hot-standby, what alternatives for savings can a better topology create, like potentially situation 2 below: Situation 2: purchase reserved multi-az setup using smaller master instances than above for the master-master hot-standby to receive the writes only. Then create and load balance several read-only slaves off the master and add/remove and/or scale up/down the read slaves based on demand. This might only cost $1000 + the on-demand usage of the read slaves. My thinking is, if I have a variable read-intensive application load, with low write load, the single level topology in situation 1 means I'm paying for a lot of resources at the write level of topology when I don't need them there. My hope is that situation 2 can yield cost savings from smaller reserved instances on the master-master resource level allowing me to scale up and down and/or out on the read-level according to demand as needed. Does anyone see a downside to doing this or know of some reason this isn't possible with RDS? Any other thoughts or advice always welcome of course. Thanks in advance, R

  • Compiled git from source, cannot access subversion repositories using git-svn

    - by haydenmuhl
    I'm setting up a CentOS dev box, and need git. At first I tried to install git using yum, but I could not connect to a yum repository that had git. Next I downloaded the git source (version 1.7.1) and compiled it. When I run the following command git svn clone svn+ssh://... I get the following error. Initialized empty Git repository in /root/main_ec/.git/ Can't locate SVN/Core.pm in @INC (@INC contains: /usr/local/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi /usr/local/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.8/i386-linux-thread-multi /usr/lib/perl5/5.8.8 .) at /usr/local/libexec/git-core/git-svn line 41. It looks like git-svn uses perl in some manner, but I don't know packages I'm missing. Can anyone help?

  • Weekend reading: Microsoft/Oracle and SkyDrive based code-editor

    - by jamiet
    A couple of news item caught my eye this weekend that I think are worthy of comment. Microsoft/Oracle partnership to be announced tomorrow (24/06/2013) According to many news site Microsoft and Oracle are about to announce a partnership (Oracle set for major Microsoft, Salesforce, Netsuite partnerships) and they all seem to be assuming that it will be something to do with “the cloud”. I wouldn’t disagree with that assessment, Microsoft are heavily pushing Azure and Oracle seem (to me anyway) to be rather lagging behind in the cloud game. More specifically folks seem to be assuming that Oracle’s forthcoming 12c database release will be offered on Azure. I did a bit of reading about Oracle 12c and one of its key pillars appears to be that it supports multi-tenant topologies and multi-tenancy is a common usage scenario for databases in the cloud. I’m left wondering then, if Microsoft are willing to push a rival’s multi-tenant solution what is happening to its own cloud-based multi-tenant offering – SQL Azure Federations. We haven’t heard anything about federations for what now seems to be a long time and moreover the main Program Manager behind the technology, Cihan Biyikoglu, recently left Microsoft to join Twitter. Furthermore, a Principle Architect for SQL Server, Conor Cunningham, recently presented the opening keynote at SQLBits 11 where he talked about multi-tenant solutions on SQL Azure and not once did he mention federations. All in all I don’t have a warm fuzzy feeling about the future of SQL Azure Federations so I hope that that question gets asked at some point following the Microsoft/Oracle announcement. Text Editor on SkyDrive with coding-specific features Liveside.net got a bit of a scoop this weekend with the news (Exclusive: SkyDrive.com to get web-based text file editing features) that Microsoft’s consumer-facing file storage service is going to get a new feature – a web-based code editor. Here’s Liveside’s screenshot: I’ve long had a passing interest in online code editors, indeed back in December 2009 I wondered out loud on this blog site: I started to wonder when the development tools that we use would also become cloud-based. After all, if we’re using cloud-based services does it not make sense to have cloud-based tools that work with them? I think it does. Project Houston Since then the world has moved on. Cloud 9 IDE (https://c9.io/) have blazed a trail in the fledgling world of online code editors and I have been wondering when Microsoft were going to start playing catch-up. I had no doubt that an online code editor was in Microsoft’s future; its an obvious future direction, why would I want to have to download and install a bloated text editor (which, arguably, is exactly what Visual Studio amounts to) and have to continually update it when I can simply open a web browser and have ready access to all of my code from wherever I am. There are signs that Microsoft is already making moves in this direction, after all the URL for their new offering Team Foundation Service doesn’t mention TFS at all – my own personalised URL for Team Foundation Service is http://jamiet.visualstudio.com – using “Visual Studio” as the domain name for a service that isn’t strictly speaking part of Visual Studio leads me to think that there’s a much bigger play here and that one day http://visualstudio.com will house an online code editor. With that in mind then I find Liveside’s revelation rather intriguing, why would a code editing tool show up in Skydrive? Perhaps SkyDrive is going to get integrated more tightly into TFS, I’m very interested to see where this goes. The larger question playing on my mind though is whether an online code editor from Microsoft will support SQL Server developers. I have opined before (see The SQL developer gap) about the shoddy treatment that SQL Server developers have to experience from Microsoft and I haven’t seen any change in Microsoft’s attitude in the three and a half years since I wrote that post. I’m constantly bewildered by the lack of investment in SQL Server developer productivity compared to the riches that are lavished upon our appdev brethren. When you consider that SQL Server is Microsoft’s third biggest revenue stream it is, frankly, rather insulting. SSDT was a step in the right direction but the hushed noises I hear coming out of Microsoft of late in regard to SSDT don’t bode fantastically well for its future. So, will an online code editor from Microsoft support T-SQL development? I have to assume not given the paucity of investment on us lowly SQL Server developers over the last few years, but I live in hope! Your thoughts in the comments section please. I would be very interested in reading them. @Jamiet
