• SQL Azure Security: DoS

  - by Herve Roggero

  Since I decided to understand in more depth how SQL Azure works I started to dig into its performance characteristics. So I decided to write an application that allows me to put SQL Azure to the test and compare results with a local SQL Server database. One of the options I added is the ability to issue the same command on multiple threads to get certain performance metrics. That's when I stumbled on an interesting security feature of SQL Azure: its Denial of Service (DoS) detection engine. What this security feature does is that it performs a check on the number of connections being established, and if the rate of connection is too high, SQL Azure blocks all communication from that machine. I am still trying to learn more about this specific feature, but it appears that going to the SQL Azure portal and testing the connection from the portal "resets" the feature and you are allowed to connect again... until you reach the login threashold. In the specific test I was performing, all the logins were successful. I haven't tried to login with an invalid account or password... that will be for next time. On my Linked In group (SQL Server and SQL Azure Security: http://www.linkedin.com/groups?gid=2569994&trk=hb_side_g) Chip Andrews (www.sqlsecurity.com) pointed out that this feature in itself could present an internal threat. In theory, a rogue application could be issuing many login requests from a NATed network, which could potentially prevent any production system from connecting to SQL Azure within the same network. My initial response was that this could indeed be the case. However, while the TCP protocol contains the latest NATed IP address of a machine (which masks the origin of the machine making the SQL request), the TDS protocol itself contains the IP Address of the machine making the initial request; so technically there would be a way for SQL Azure to block only the internal IP address making the rogue requests.  So this warrants further investigation... stay tuned...

• Combine the Address & Search Bars in Firefox

  - by Asian Angel

  The Search Bar in Firefox is very useful for finding additional information or images while browsing but the UI space it takes up can be frustrating at times. Now you can reclaim that UI space and still have access to all that searching goodness with the Foobar extension. Note: This is about the Foobar Firefox extension and not to be confused with Foobar2000 the open source music player. Before If you have the “Search Bar” displayed there is no doubt that it is taking up valuable space in your browser’s UI. What you need is the ability to reclaim that UI space and still have the same access to your search capability as before…no more sacrificing one for a gain with the other. After As soon as you have installed the extension you can see that the top part of your browser will look much sleeker without the “Search Bar” to clutter it up. The “Search Engine Icon” will now be visible inside of your “Address Bar” as seen here. You will be able to access the same “Search Engine Menu” as before by clicking on the “Search Engine Icon”. There are two display modes for search results (setting available in the “Options”). The first one shown here is “Simple Mode” where all results are in a condensed format. Notice that not only are there search suggestions but also “Bookmarks & History” listings as well. You can literally get the best of both when conducting a search. Note: The number of entries for search suggestions and bookmark/history listings can be adjusted higher or lower in the “Options”. The second one is “Rich Mode” where the results are shown with more details. Choose the “mode” that best suits your personal style. For our first example you can see the results when we conducted a quick search on “Windows 7” (using the first of the three offerings shown from Bing). Our second example was a search for “Flowers” using our Photobucket search engine. Once again nice results opened in a new tab for us. Options The options are easy to go through. It is really nice to be able to choose the number of results that you want displayed and the format that you want them shown in. Note: Changing the “Suggestion popup style” will require a browser restart to take effect. Conclusion If you love using the “Search Bar” in Firefox but want to reclaim the UI space then you will definitely want to add this extension to your browser. The ability to customize the number of results and choose the formatting make this extension even better.

• Http 400 'Bad Request' and win32status 1450 when larger messages are sended to a WCF service

  - by Tim Mahy

  we sometimes receive Http 400 bad request resultcodes when posting a large file (10mb) to a WCF service hosted in IIS 6. We can reproduce this using SOAP UI and it seems that it is unpredictable when this happens. In our WCF log the call is not received, so we believe that the request does not reach the ASP.NET nor WCF runtime. This happens on multiple websites on the same machine each having their own application pool. All IIS settings are default, only in ASP.NET and WCF we allow bigger readerQuota's etc.... The win32status that is logged in the IIS log is 1450 which we think means "error no system resources". So now the question: a) how can we solve this b) (when a is not applicable :) ) which performance counters or logs are usefull to learn more about this problem? greetings, Tim

• What are the best practices for phasing out obsolete code?

  - by P.Brian.Mackey

  I have the need to phase out an obsolete method. I am aware of the [Obsolete] attribute. Does Microsoft have a recommended best practice guide for doing this? Here's my current plan: A. I do not want to create a new assembly because developers would have to add a new reference to their projects and I expect to get a lot of grief from my boss and co-workers if they must do this. We also do not maintain multiple assembly versions. We only use the latest version. Changing this practice would require changing our deployment process which is a big issue (have to teach people how to do things with TFS instead of FinalBuilder and get them to give up FinalBuilder) B. Mark the old method obsolete. C. Because the implementation is changing (not the method signature), I need to rename the method rather than create an overload. So, to make users aware of the proper method I plan to add a message to the [Obsolete] attribute. This part bothers me, because the only change I'm making is decoupling the method from the connection string. But, because I'm not adding a new assembly, I see no way around this. Result: [Obsolete("Please don't use this anymore because it does not implement IMyDbProvider. Use XXX instead.")]; /// <summary> /// /// </summary> /// <param name="settingName"></param> /// <returns></returns> public static Dictionary<string, Setting> ReadSettings(string settingName) { return ReadSettings(settingName, SomeGeneralClass.ConnectionString); } public Dictionary<string, Setting> ReadSettings2(string settingName) { return ReadSettings(settingName);// IMyDbProvider.ConnectionString private member added to class. Probably have to make this an instance method. }

• "sed" regex help: Replacing characters

  - by powerbar

  I want to change characters in a XML file by using sed. The input looks like this: <!-- Input --> <root> <tree foo="abcd" bar="abccdcd" /> <dontTouch foo="asd" bar="abc" /> </root> Now I want to change all c to X in the bar tag of the tree element. <!-- Output --> <root> <tree foo="abcd" bar="abXXdXd" /> <dontTouch foo="asd" bar="abc" /> </root> How is the correct sed command? Please consider, there can be more than one occurence of c (next to each other or not) in one tag... I tried this myself, but it won't change multiple c, and it does append a X :( sed -i 's/\(<tree.*bar=\".*\)c\(.*\"\/>\)/\1X\2/g' Input.xml

• Tömörítés becslése - Compression Advisor

  - by lsarecz

  Az Oracle Database 11g verziójától már OLTP adatbázisok is hatékonyan tömöríthetok az Advanced Compression funkcióval. Nem csak a tárolandó adatok mennyisége csökken ezáltal felére, vagy akár negyedére, de az adatbázis teljesítménye is javulhat, amennyiben I/O korlátos a rendszer (és általában az). Hogy pontosan mekkora tömörítés várható az Advanced Compression bevezetésével, az kiválóan becsülheto a Compression Advisor eszközzel. Ez nem csak az OLTP tömörítés mértékét, de 11gR2 verziótól kezdve a HCC tömörítés arányát is becsülni tudja, amely Exadata Database Machine, Pillar Axiom illetve ZFS Storage alkalmazásával érheto el. A HCC tömörítés becsléséhez csak 11gR2 adatbázisra van szükség, nem kell hozzá a speciális célhardver (Exadata, Pillar, ZFS). A Compression Advisor valójában a DBMS_COMPRESSION package használatával érheto el. A package-hez tartozik 6 konstans, amellyel a kívánt tömörítési szintek választhatók ki: Constant Type Value Description COMP_NOCOMPRESS NUMBER 1 No compression COMP_FOR_OLTP NUMBER 2 OLTP compression COMP_FOR_QUERY_HIGH NUMBER 4 High compression level for query operations COMP_FOR_QUERY_LOW NUMBER 8 Low compression level for query operations COMP_FOR_ARCHIVE_HIGH NUMBER 16 High compression level for archive operations COMP_FOR_ARCHIVE_LOW NUMBER 32 Low compression level for archive operations A GET_COMPRESSION_RATIO tárolt eljárás elemzi a tömöríteni kívánt táblát. Mindig csak egy táblát, vagy opcionálisan annak egy partícióját tudja elemezni úgy, hogy a tábláról készít egy másolatot egy külön erre a célra kijelölt/létrehozott táblatérre. Amennyiben az elemzést egyszerre több tömörítési szintre futtatjuk, úgy a tábláról annyi másolatot készít. A jó közelítésu becslés (+-5%) feltétele, hogy táblánként/partíciónként minimum 1 millió sor legyen. 11gR1 esetében még a DBMS_COMP_ADVISOR csomag GET_RATIO eljárása volt használatos, de ez még nem támogatta a HCC becslést. Érdemes még megnézni és kipróbálni a Tyler Muth blogjában publikált formázó eszközt, amivel a compression advisor kimenete alakítható jól értelmezheto formátumúvá. Végül összegezném mit is tartalmaz az Advanced Compression opció, mivel gyakran nem világos a felhasználóknak miért kell fizetni: Data Guard Network Compression Data Pump Compression (COMPRESSION=METADATA_ONLY does not require the Advanced Compression option) Multiple RMAN Compression Levels (RMAN DEFAULT COMPRESS does not require the Advanced Compression option) OLTP Table Compression SecureFiles Compression and Deduplication Ez alapján RMAN esetében például a default compression (BZIP2) szint ingyen használható, viszont az új ZLIB Advanced Compression opciót igényel. A ZLIB hatékonyabban használja a CPU-t, azaz jóval gyorsabb, viszont kisebb tömörítési arány érheto el vele.

• Postgres error messages in Apache error log

  - by Warren Pena

  I'm running Apache 2.2, PHP 5.2, and Postgres 8.2 on Windows, and I'm seeing something funky in Apache's error.log file. Occasionally, I'll see the message "row number -1 is out of range 0..-1" pop up over and over. Unlike all the other lines in that log file, there's no timestamp or log level. Just that exact string. Googling around, it appears that message is, character for character, a common Postgres error message, but is not an Apache error. I've seen it happen multiple times, and on several different servers. I can't seem to reproduce it, though. I've tried throwing all sorts of error ridden database queries and result set inquiries at Postgres via PHP, and none of them seem to trigger that line being written to the log file. Is it possible for Postgres errors to be ending up in my Apache log file, and if so, how? What would trigger an error message like that? Thanks!

• What's New in Oracle's EPM System?

  - by jmorourke

  Oracle’s EPM System R11.1.2.2  is now generally available to customers and partners on the download center.  Although the release number doesn’t sound significant, this is a major release of Oracle’s Hyperion EPM Suite with new modules as well as significant enhancements across the suite.  This release was announced back on April 4th as part of Oracle’s Business Analytics Strategy launch, so analytics is a key aspect of the release.  But the three biggest pieces of news in this release are Oracle Hyperion Planning support for the Exalytics In-Memory Machine, the new Project Financial Planning Application and the new Account Reconciliations Manager module. The Oracle Exalytics In-Memory Machine was announced back in October 2011, at Oracle OpenWorld.  It’s the latest installment from Oracle in a line of engineered systems that combine Oracle Sun hardware, with Oracle database and application technologies – in solutions that are designed to provide high scalability and performance for specific tasks.  Exalytics is the first engineered system specifically designed for high performance analytics.  Running in-memory versions of Oracle Essbase, as well as the Oracle TimesTen database and Oracle BI tools, Exalytics provides speed of thought response times for complex analytic processes with advanced visualizations.  Early adopter customers have achieved 5X to 100X faster interactivity and 6X to 10X faster planning cycles.  Hyperion Planning running with Oracle Exalytics will support enterprise-wide planning, budgeting and forecasting with more detailed data, with hundreds to thousands of users across an organization getting speed of thought performance. The new Hyperion Project Financial Planning application delivered with EPM 11.1.2.2 is also great news for Oracle customers.  This application follows on the heels of other special-purpose planning applications that Oracle has delivered for Workforce and Capital Asset planning.  It allows Project Managers to identify project-related expenses and revenues, plan and propose new projects, and track results over time. Finance Managers can evaluate and compare different projects, manage the funding process, monitor and report the actual financial results and impacts of projects and project portfolios. This new application is applicable to capital projects, contract projects and indirect projects like IT and HR projects across all industries.  This application is a great complement to existing Project Management applications, and helps bridge the gap between these applications, and the financial planning and budgeting process. Account reconciliations has to be one of the biggest bottlenecks and risks in the financial close and reporting process, and many organizations rely on spreadsheets and manual processes to perform this critical process.  To help address this problem, Oracle developed an Account Reconciliation Manager module that is being delivered as part of Oracle Hyperion Financial Close Management.   This module helps automate and streamline account reconciliations and eliminates the chances for errors, omissions and fraud.  But unlike standalone account reconciliation packages, it’s integrated with the rest of the Oracle Hyperion Financial Close suite, and can integrate balances from any source system.  This can help alleviate a major bottleneck in the financial close process, increase accuracy and reduce risk, and can complement existing investments in Hyperion Financial Management, as well as Oracle and non-Oracle transaction processing systems. Other enhancements in this release include an enhanced Web 2.0 interface for Hyperion Planning and Hyperion Financial Management (HFM), configurable dimensionality in HFM, new Predictive Planning feature in Hyperion Planning, new Detailed Profitability feature in Hyperion Profitability and Cost Management, new Smart View interface for Hyperion Strategic Finance, and integration of the Hyperion applications with JD Edwards Financials.

• IIS 7.x Application Pool Best Practices

  - by Eric

  We are about to deploy a bunch of sites to some new servers. I have the following questions about application pools: 1) It seems advisable to have an application pool per website. Are there any caveats to this approach? Can one application pool, for example, hog all the CPU, Memory, Etc...? 2) When should you allow multiple worker processes in an application pool. When should you not? 3) Can private memory limit be used to prevent one application pool from interfering with another? Will setting it too low cause valid requests to recycle the application pool without getting a valid response? 4) What is the difference between private and virtual memory limits? 5) Are there compelling reasons NOT to run one application pool per site? Thanks!

• Entity Framework with large systems - how to divide models?

  - by jkohlhepp

  I'm working with a SQL Server database with 1000+ tables, another few hundred views, and several thousand stored procedures. We are looking to start using Entity Framework for our newer projects, and we are working on our strategy for doing so. The thing I'm hung up on is how best to split the tables into different models (EDMX or DbContext if we go code first). I can think of a few strategies right off the bat: Split by schema We have our tables split across probably a dozen schemas. We could do one model per schema. This isn't perfect, though, because dbo still ends up being very large, with 500+ tables / views. Another problem is that certain units of work will end up having to do transactions that span multiple models, which adds to complexity, although I assume EF makes this fairly straightforward. Split by intent Instead of worrying about schemas, split the models by intent. So we'll have different models for each application, or project, or module, or screen, depending on how granular we want to get. The problem I see with this is that there are certain tables that inevitably have to be used in every case, such as User or AuditHistory. Do we add those to every model (violates DRY I think), or are those in a separate model that is used by every project? Don't split at all - one giant model This is obviously simple from a development perspective but from my research and my intuition this seems like it could perform terribly, both at design time, compile time, and possibly run time. What is the best practice for using EF against such a large database? Specifically what strategies do people use in designing models against this volume of DB objects? Are there options that I'm not thinking of that work better than what I have above? Also, is this a problem in other ORMs such as NHibernate? If so have they come up with any better solutions than EF?

• Building Single Page Apps on the Microsoft Stack

  - by Stephen.Walther

  Thank you everyone who came to my talk last night on Building Single Page Apps on the Microsoft Stack. I’ve attached the slides and code samples below. Here’s a quick summary of the talk. I argued that Single Page Apps are better than traditional Server Side Apps because: Single Page Apps are Stateful – In a traditional server-side app, whenever you navigate to a new page, all of your previous state is lost. It is like rebooting your computer whenever you perform any action In a Single Page App, Your Presentation Layer is Not Miles Away – In a traditional server-side app, because everything happens on the server, your presentation layer is separated from the user by space and time. In a Single Page App, the presentation layer is in the browser and not the server (which is the right place for a presentation layer). A Single Page App Respects the Web – It is easier to take advantage of HTML5 and related standards when building a Single Page App. Next, I recommended using the following four technologies when building a web application: Knockout – This is how you create your presentation layer. ASP.NET Web API – This is how you expose JSON data from your web server and perform server-side validation. HTML5 – This is how you implement client-side validation. Sammy – This is how you implement client-side routing and create a Single Page App with multiple virtual pages. There are code samples in the download (look in the Samples folder) which demonstrate how all of these technologies work when building Single Page Apps. Powerpoint Sample Code

  - by Roman Schindlauer

  If you're just beginning to get familiar with StreamInsight, you may be looking for a way to get started. What are the basics? How can I get my first StreamInsight application running so I can see how it works? Where is the 'front door' that will get me going? If that describes you, then this blog entry might be just what you need. If you're already a StreamInsight wiz, keep reading anyway - you may find some helpful links here that you weren't aware of. But here's what we'd like from you experienced readers in particular: if you know of other good resources that we missed, please feel free to add them in the comments below. We appreciate you sharing your expertise. The Book The basic documentation for StreamInsight is located in the MSDN Library (Microsoft StreamInsight 2.1). You'll notice that previous versions of StreamInsight are still there (1.2 and 2.0), but if you're just getting started you can stick to the 2.1 section. The documentation has been organized to function as reference material, which is fine after you're familiar with the technology. But if you're trying to learn the basics, you might want to take a different path instead of just starting at the top. The following is one map you can use. What Is StreamInsight? Here is a sequence of topics that should give you a good overview of what StreamInsight is and how it works: Overview answers the question, "what is it?" StreamInsight Server Architecture gives you a quick look at a high-level architectural drawing StreamInsight Concepts lays out an overview of the basic components Deploying StreamInsight Entities to a StreamInsight Server describes the mechanics of how these components work together Getting an Example Running Once you have this background, go ahead and install StreamInsight and get a basic example up and running: Installation download and install the software StreamInsight Examples walk through a set of 3 simple StreamInsight applications that work together to demonstrate what you learned in the topics above; you can copy and paste the code into Visual Studio, compile, and run That's it - you now have a real, functioning StreamInsight system! Now that you have a handle on the basics, you might want to start digging deeper. Digging Deeper Here's a suggested path through the documentation to help you understand the next layer of StreamInsight technologies: Using Event Sources and Event Sinks sources supply data and sinks consume it; this topic gives you an overview of how they work Publishing and Connecting to the StreamInsight Server practical details on how to set up a StreamInsight server A Hitchhiker’s Guide to StreamInsight 2.1 Queries queries are the heart of how StreamInsight performs data analytics, and this whitepaper will help you really understand how they work Using StreamInsight LINQ root through this section for technical details on specific query components Using the StreamInsight Event Flow Debugger in addition to troubleshooting, the debugger is a great way to learn more about what goes on inside a StreamInsight application And Even Deeper Finally, to get a handle on some of the more complex things you can do with StreamInsight, dig into these: Input and Output Adapters adapters can be useful for handling more complex sources and sinks Building Resilient StreamInsight Applications a resilient application is able to recover from system failures Operations this section will help you monitor and troubleshoot a running StreamInsight system The StreamInsight Community As you're designing and developing your StreamInsight solutions, you probably will find it helpful to see working examples or to learn tips and tricks from others.

• match and export subject line and from header with procmail

  - by Nick

  I would like to use procmail or a combination of procmail and formail to take an email message and match a specific keyword in the Subject: line/header, and if matched, export the contents of the Subject: line/header, and the contents of the From: line/header to a perl script. I have researched this, and have not been able to get this working all the way. I am new to procmail, and I assume I need to use a nesting block, but I am not sure how to get the data and then export it. I have been able to match the subject line and export it to a perl script where it is read via ARGV0, but get lost when trying to export and match multiple fields. I tried subscribing to the procmail listserv, but it appears to be broken. Can someone help me with this, please?

• Policy Administration is the Top 2011 IT Priority for Insurers

  - by helen.pitts(at)oracle.com

  The current issue of Insurance Networking News includes an interesting column by Novarica's Matt Josefowicz.  Recent research by the firm revealed that policy administration replacement or extension is the most common strategic IT project for insurers this year.  The article goes on to note that insurers are keenly focused on the business capabilities that can be delivered once the system is in production as well as the ability to leverage agile development methodologies and true business/IT collaboration during implementation. The results are not too surprising given that policy administration is a mission-critical system for life and annuity insurers.  As Josefowicz notes, "Core systems are called core for a reason--they are at the heart of the insurer's ability to function.  Replacing them is not to be done lightly, but failing to replace them can mean diminishing the ability to compete or function effectively as a company." Insurers can no longer rely on inflexible policy administration systems that impede their ability to rapidly configure and bring to innovative new products, add riders, support changing business processes and take advantage of market opportunities.  The ability to leverage the policy administration systems to better service customers and distribution channels by providing real-time access to policy information throughout the policy lifecycle is also critical to sustain loyalty and further fuel growth.Insurers can benefit from a modern, adaptive policy administration system, like Oracle Insurance Policy Administration for Life and Annuity.  You can learn more about the industry's most highly advanced, rules-based system, which is unmatched for its highly flexible, rules-based configurability, performance and extensibility, as well as global market industry trends by viewing a complimentary, on-demand Webcast, Adapt, Transform and Grow:  Accelerate Speed to Market with Adaptive Insurance Policy Administration.Data conversions can be a daunting process for many insurers when deciding to modernize, in particular when consolidating from multiple, disparate legacy policy administration systems to a single new platform.  Migrating from a legacy system requires a well-thought out approach that builds on the industry's best thinking from previous modernization efforts and takes data migration off the critical path by leveraging proven methodology and tools to capitalize on the new system's capabilities.  We'll discuss more about this approach in a future Oracle Insurance blog.Helen Pitts is senior product marketing manager for Oracle Insurance's life and annuities solutions.

• Translation and Localization Resources for UX Designers

  - by ultan o'broin

  Here is a handy list of translation and localization-related resources for user experience professionals. Following these will help you design an easily translatable user experience. Most of the references here are for web pages or software. Fundamentally, remember your designs will be consumed globally, and never divorce the design process from the development or deployment effort that goes into bringing your designs to life in code. Ask yourself today: Do you know how the text you are using in your designs are delivered to the customer, even in English? Key areas that UX designers always seen to fall foul of, in my space anyway, are: Terminology that is impossible to translate (jargon, multiple modifiers, gerunds) or is used inconsistently Poorly written, verbose text (really, just write well in English, no special considerations) String construction (concatenation of parts assembled dynamically) Composite widget positioning (my favourite) Hard-coded fonts, small font sizes, or character formatting or casing that doesn't work globally Format that is not separate from content Restricted real estate not allowing for text expansion in translation Forcing formatting with breaks, and hard-coding alphabetical sorting Graphics that do not work in Bi-Di languages (because they indicate directionality and can't flip) or contain embedded text. The problems of culturally offensive icons are well known by now in the enterprise applications space, though there are some dangers, such as the use of flags to indicate language, for example.

• Idea of an algorithm to detect a website's navigation structure?

  - by Uwe Keim

  Currently I am in the process of developing an importer of any existing, arbitrary (static) HTML website into the upcoming release of our CMS. While the downloading the files is solved successfully, I'm pulling my hair off when it comes to detect a site structure (pages and subpages) purely from the HTML files, without the user specifying additional hints. Basically I want to get a tree like: + Root page 1 + Child page 1 + Child page 2 + Child child page1 + Child page 3 + Root page 2 + Child page 4 + Root page 3 + ... I.e. I want to be able to detect the menu structure from the links inside the pages. This has not to be 100% accurate, but at least I want to achieve more than just a flat list. I thought of looking at multiple pages to see similar areas and identify these as menu areas and parse the links there, but after all I'm not that satisfied with this idea. My question: Can you imagine any algorithm when it comes to detecting such a structure? Update 1: What I'm looking for is not a web spider, but an algorithm do create a logical tree of the relationship of the pages to be able to create pages and subpages inside my CMS when importing them. Update 2: As of Robert's suggestion I'll solve this by starting at the root page, and then simply parse links as you go and treat every link inside a page simply as a child page. Probably I'll recurse not in a deep-first manner but rather in a breadth-first manner to get a more balanced navigation structure.

• What's constitute an entry on the IPTables and how to find out which client it is originated from

  - by cbd

  I have a Billion BiPac 7700N Modem/Router/Access Point and I connect another router (TP-Link TL-WR1043ND) in wan-bypass mode to extend the wireless coverage. Lately, I noticed that the connection through TP-Link has been dropping out quite regularly. Having read some posts on the Internet, I checked system log on 7700N and found that there are many "nf_conntract: expectation table full" errors, which I suppose the iptables are full. My questions: What does constitute an entry on the iptable? Is it a client or a connection (which means one client can have multiple connections) How could I find out where are those connections originated from? Note: Many reported that the issue is usually related to having torrents running but I don't have any torrents running. Thank you.

• How to symlink folders and exclude certain files

  - by Jarrod White

  Hey Guys, I'm not a server guru (unfortunately) but have a decent knowledge of linux & bsd. I'm trying to symlink multiple instances of HLDS (game server) but need to exclude certain folders & config files to achieve this properly. I need to do it this way as HLDS loads many mods automatically, and putting an exception to disable the mods doesnt work for all of them. so basically i want: /home/user/hlds-install (the base install) /home/user/server1 /home/user/server2 etc... and then be able to manually put any configs/mods ive excluded into the server dir's so that each server can be configured individually. Can anyone tell me how to do this, perhaps some sort of bash script so that I can just change the targets to run it each time i want to create a new one. I have quite a number to make so doing the whole thing manually for each one definately isn't an option and im all for working smarter, not harder! Thanks :)

• Re-streaming RTMP stream

  - by Yvan JANSSENS

  I have a set of local RTMP stream servers in my network, but I want them to be reachable outside. The bandwidth is too narrow to serve multiple clients on the streamservers of my network, so the idea is to pull the local RTMP streams on a computer serving as a gateway, which pushes them on his turn to a hosted streaming provider. It is not possible to let the sources of the stream push their stream directly to the server outside due to network policy restrictions. Scheme of what I'm trying to accomplish: Internal network | External network ------------ ------------ ----------------------- | internal | <---- | Gateway | ------> | streamserver outside| | streams | ------------ ----------------------- ------------ | ^ | | | ----------- | | clients | | ----------- My question now is: which application which can pull a live stream from an RTMP source (Flash Media Server) and push it to another one (Flash Media Server at hosting provider).

• New Management Console in Java SE Advanced 8u20

  - by Erik Costlow-Oracle

  Java SE 8 update 20 is a new feature release designed to provide desktop administrators with better control of their managed systems. The release notes for 8u20 are available from the public JDK release notes page. This release is not a Critical Patch Update (CPU). I would like to call attention to two noteworthy features of Oracle Java SE Advanced, the commercially supported version of Java SE for enterprises that require both support and specialized tools. The new Advanced Management Console provides a way to monitor and understand client systems at scale. It allows organizations to track usage and more easily create and manage client configuration like Deployment Rule Sets (DRS). DRS can control execution of tracked applications as well as specify compatibility of which application should use which Java SE installation. The new MSI Installer integrates into various desktop management tools, making it easier to customize and roll out different Java SE versions. Advanced Management Console The Advanced Management Console is part of Java SE Advanced designed for desktop administrators, whose users need to run many different Java applications. It provides usage tracking for those Applet & Web Start applications to help identify them for guided DRS creation. DRS can then be verified against the tracked data, to ensure that end-users can run their application against the appropriate Java version with no prompts. Usage tracking also has a different definition for Java SE than it does for most software applications. Unlike most applications where usage can be determined by a simple run-count, Java is a platform used for launching other applications. This means that usage tracking must answer both "how often is this Java SE version used" and "what applications are launched by it." Usage Tracking One piece of Java SE Advanced is a centralized usage tracker. Simply placing a properties file on the client informs systems to report information to this usage tracker, so that the desktop administrator can better understand usage. Information is sent via UDP to prevent any delay on the client. The usage tracking server resides at a central location on the intranet to collect information from those clients. The information is stored in a normalized database for performance, meaning that a single usage tracker can handle a large number of clients. Guided Deployment Rule Sets Deployment Rule Sets were introduced in Java 7 update 40 (September 2013) in order to help administrators control security prompts and guide compatibility. A previous post, Deployment Rule Sets by Example, explains how to configure a rule set so that most applications run against the most secure version but a specific applet may run against the Java version that was current several years ago. There are a different set of questions that can be asked by a desktop administrator in a large or distributed firm: Where are the Java RIAs that our users need? Which RIA needs which Java version? Which users need which Java versions? How do I verify these answers once I have them? The guided deployment rule set creation uses usage tracker data to identify applications both by certificate hash and location. After creating the rules, a comparison tool exists to verify them against the tracked data: If you intend to run an RIA, is it green? If something specific should be blocked, is it red? This makes user-testing easier. MSI Installer The Windows Installer format (MSI) provides a number of benefits for desktop administrators that customize or manage software at scale. Unlike the basic installer that most users obtain from Java.com or OTN, this installer is built around customization and integration with various desktop management products like SCCM. Desktop administrators using the MSI installer can use every feature provided by the format, such as silent installs/upgrades, low-privileged installations, or self-repair capabilities Customers looking for Java SE Advanced can download the MSI installer through their My Oracle Support (MOS) account. Java SE Advanced The new features in Java SE Advanced make it easier for desktop administrators to identify and control client installations at scale. Administrators at organizations that want either the tools or associated commercial support should consider Java SE Advanced.

• Should programmers itemize testing in testing? [on hold]

  - by Patton77

  I recently hired a programming team to do a port of my iPad app to the iPhone and Android platforms. Now, in a separate contract, I am asking them to implement a bunch of tips on how to play the app, similar like you would find in Candy Crush or Cut the Rope. They want to charge 12 hours @ $35/hr for the "Testing all of the Tips", telling me that normally it would take them more than 25 hours but that they will 'bear the difference'. I am not familiar with this level of itemization, but maybe it's a new practice? I am used to devs doing their own quality control, and then having a testing/acceptance period. They are using Cocos 2D-X, and they say that the tips going to multiple platforms makes all of the hours jack up. I feel like they might be overcharging, and it's difficult for me to know because it's kind of like with a mechanic. "It took us 5 hours to replace the radiator". How can you dispute that? It seems to me that most of you would charge for the work but NOT for hours that you are 'testing'. Am I missing something? Thanks for any help and advice you can give!

• Copy Formatting in Word

  - by Ahamad Patan

  Many a times you may need to copy the "Format" in Word. The "Copy Format" feature lets you quickly and easily "copy" all the formatting characteristics from one group of selected text to another. This is helpful when you have several headings that you want consistent formatting. Here are steps on how to Copy Formatting: 1. Select, or highlight, the item of text containing the format you wish to copy. 2. Office 2003 - Click on the Format Painter Button in the Standard Toolbar (looks like Paintbrush). Office 2007 - Format Painter Button is located on the Home tab (looks like a Paintbrush). Office 2003 - An I-beam with a small cross to the left will appear as you move your mouse. Office 2007 - An I-beam with a small paintbrush will appear as you move your mouse. 3. Select the text you wish to copy the formatting to. 4. Formatting of the selected text will automatically change. For multiple formatting changes, double-click on the Format Painter button in Step 2. Remember, you'll have to click it again to deselect it or press Esc.

• How to make a legacy system time-zone sensitive?

  - by Jerry Dodge

  I need to implement time zones in a very large and old Delphi system, where there's a central SQL Server database and possibly hundreds of client installations around the world in different time zones. The application already interacts with the database by only using the date/time of the database server. So, all the time stamps saved in both the database and on the client machines are the date/time of the database server when it happened, never the time of the client machine. So, when a client is about to display the date/time of something (such as a transaction) which is coming from this database, it needs to show the date/time converted to the local time zone. This is where I get lost. I would naturally assume there should be something in SQL to recognize the time zone and convert a DateTime field dynamically. I'm not sure if such a thing exists though. If so, that would be perfect, but if not, I need to figure out another way. This Delphi system (multiple projects) utilizes the SQL Server database using ADO components, VCL data-aware controls, and QuickReports (using data sources). So, there's many places where the data goes directly from the database query to rendering on the screen, without any code to actually put this data on the screen. In the end, I need to know when and how should I get the properly converted time? What is the proper way to ensure that I handle Dates and Times correctly in a legacy application?
