Symbian Foundation logo. Home Screen of Nokia Belle Feature Pack 2 (Last version of Symbian)Developer. Symbian Ltd. Symbian was used by many major mobile phone brands, like Samsung, Motorola, Sony Ericsson, and above all by Nokia. It was also prevalent in Japan by brands including Fujitsu, Sharp and Mitsubishi. As a pioneer that established the smartphone industry, it was the most popular smartphone OS on a worldwide average until the end of 2. Android, as Google and its partners achieved wide adoption. Symbian OS was essentially a shell system and required an additional user interface (as middleware) to form a complete operating system. Symbian OS became prominent from the S6. Series 6. 0) platform built by Nokia, first released in 2. Nokia smartphones. Symbian OS eventually became the most widely used smart mobile operating system, though notably not as popular in North America. UIQ was another Symbian user interface mostly used by Motorola and Sony Ericsson, whereas in Japan the MOAP(S) platform was created by carrier NTT Do. Co. Mo. Applications of these interfaces were not compatible with each other, despite each being built atop Symbian OS.
Nokia became the majority shareholder in Symbian Ltd. Symbian^1 (or S6. Edition) was created as a result in 2. X-plore - file manager for mobile devices.

Home Screen of Nokia Belle Feature Pack 2 (Last version of Symbian) Developer: Symbian Ltd. Symbian Toys - NEWS. Wellcome on my personal website! I'm Marco Bellino a Freelance Symbian Developer from Turin, Italy. I've been electedForum Nokia Champions. Symbian^2 (based on MOAP) was used by carrier NTT Do. Co. Mo, one of the members of the Foundation, for the Japanese market. Symbian^3 was released in 2. S6. 0 5th Edition, by which time it became fully open source. Symbian^3 received the Anna and Belle updates in 2. In June 1. 99. 8, Psion Software became Symbian Ltd., a major joint venture between Psion and phone manufacturers Ericsson, Motorola, and Nokia. Afterwards, different software platforms were created for Symbian, backed by different groups of mobile phone manufacturers. They include S6. 0 (Nokia, Samsung and LG), UIQ (Sony Ericsson and Motorola) and MOAP(S) (Japanese only such as Fujitsu, Sharp etc.). With no major competition in the smartphone OS then (Palm OS and Windows Mobile were comparatively small players), Symbian reached as high as 6. All of this discouraged third- party developers, and served to cause the native app ecosystem for Symbian not to evolve to a scale later reached by Apple's App Store or Android's Google Play. By contrast, i. Phone OS (renamed i. OS in 2. 01. 0) and Android had comparatively simpler design, provided easier and much more centralized infrastructure to create and obtain third- party apps, offered certain developer tools and programming languages with a manageable level of complexity, and having capabilities such as multitasking and graphics in order to meet future consumer demands. Although Symbian was difficult to program for, this issue could be worked around by creating Java Mobile Edition apps, ostensibly under a . Symbian OS and its associated user interfaces S6. UIQ and MOAP(S) were contributed by their owners Nokia, NTT Do. Co. Mo, Sony Ericsson and Symbian Ltd., to the foundation with the objective of creating the Symbian platform as a royalty- free, open source software, under the OSI- and FSF- approved Eclipse Public License (EPL). The platform was designated as the successor to Symbian OS, following the official launch of the Symbian Foundation in April 2. The Symbian platform was officially made available as open source code in February 2. Since then Nokia maintained its own code repository for the platform development, regularly releasing its development to the public repository. Its objective was to publish the source code for the entire Symbian platform under the OSI- and FSF- approved Eclipse Public License (EPL). The code was published under EPL on 4 February 2. Symbian Foundation reported this event to be the largest codebase moved to Open Source in history. Several other frameworks were deployed to the platform, among them Standard C/C++, Python, Ruby, and Flash Lite. IDEs and SDKs were developed and then released for free, and app development for Symbian picked up. In November 2. 01. Symbian Foundation announced that due to changes in global economic and market conditions (and also a lack of support from members such as Samsung. Symbian Foundation would remain the trademark holder and licensing entity and would only have non- executive directors involved. With market share sliding from 3. Q3. 20. 10 to 3. 1% in Q4. Research in June 2. Symbian at the time of publication were planning to abandon the platform. Accenture will provide Symbian- based software development and support services to Nokia through 2. Nokia employees became Accenture employees as of October 2. S6. 0 was designed to be manipulated by a keyboard- like interface metaphor, such as the ~1. QWERTY keyboards. AVKON- based software is binary- compatible with Symbian versions up to and including Symbian^3. Symbian^3 includes the Qt framework, which is now the recommended user interface toolkit for new applications. Qt can also be installed on older Symbian devices. Symbian^4 was planned to introduce a new GUI library framework specifically designed for a touch- based interface, known as . When more applications gradually feature a user interface reworked in Qt, the legacy S6. AVKON) will be deprecated and no longer included with new devices at some point, thus breaking binary compatibility with older S6. Symbian was the first mobile platform to make use of Web. Kit (in June 2. 00. Current Symbian release (Symbian Belle) has support for 4. Nokia makes available on device in language packs (set of languages which cover the languages commonly spoken in the area where the device variant is intended to be sold). All language packs have in common English (or a locally relevant dialect of it). The supported languages . Qt supports the older Symbian/S6. Feature Pack 1, a. S6. 0 3. 1) and Symbian/S6. Edition (a. k. a. S6. 0 5. 0. 1b) releases, as well as the new Symbian platform. It also supports Maemo and Mee. Go, Windows, Linux and Mac OS X. It can be used with either Qt Creator, or Carbide (the older IDE previously used for Symbian development). Apps compiled for the simulator are compiled to native code for the development platform, rather than having to be emulated. Before the release of the Qt SDK, this was the standard development environment. There were multiple platforms based on Symbian OS that provided software development kits (SDKs) for application developers wishing to target Symbian OS devices, the main ones being UIQ and S6. Individual phone products, or families, often had SDKs or SDK extensions downloadable from the maker's website too. The SDKs contain documentation, the header files and library files needed to build Symbian OS software, and a Windows- based emulator (. Up until Symbian OS version 8, the SDKs also included a version of the GNU Compiler Collection (GCC) compiler (a cross- compiler) needed to build software to work on the device. Symbian OS 9 and the Symbian platform use a new application binary interface (ABI) and needed a different compiler. A choice of compilers is available including a newer version of GCC (see external links below). Unfortunately, Symbian C++ programming has a steep learning curve, as Symbian C++ requires the use of special techniques such as descriptors, active objects and the cleanup stack. This can make even relatively simple programs initially harder to implement than in other environments. It is possible that the techniques, developed for the much more restricted mobile hardware and compilers of the 1. As of 2. 01. 0, these issues are no longer the case when using standard C++, with the Qt SDK. Symbian C++ programming is commonly done with an integrated development environment (IDE). For earlier versions of Symbian OS, the commercial IDE Code. Warrior for Symbian OS was favoured. The Code. Warrior tools were replaced during 2. Carbide. c++, an Eclipse- based IDE developed by Nokia. Carbide. c++ is offered in four different versions: Express, Developer, Professional, and OEM, with increasing levels of capability.

Mythbusting: Concurrent Update/Insert Solutions . Swart. Update: This is a post on the topic of UPSERT. See my more recent post SQL Server UPSERT Patterns and Antipatterns. I’ve recently come across a large number of methods that people use to avoid concurrency problems when programming an Insert/Update query. Rather than argue with some of them. I set out to test out how valid each method by using experiment! Here’s the myth: Does Method X really perform Insert/Update queries concurrently, accurately and without errors? The last example is a double-nested NOT EXISTS query. That is, it has a NOT EXISTS clause within a NOT EXISTS clause. Formally, it answers the question “. MySQL INSERT Stored Procedure example. Source code to create and add "sql insert stored procedure" to catalog. The following example is for creating a simple. Can you please help. This is not working for me. DELIMITER // CREATE PROCEDURE verifyAndUpdate27(in searchName varchar(12), in searchId bigint, inout result int). And just like the Discovery Channel show Mythbusters, I’m going to call each method/procedure/myth either busted, confirmed or plausible based on the effectiveness of each method. Actually, feel free to follow along at home (on development servers). Nothing here is really dangerous. Here’s what my stored procedure should do. The stored procedure should look in a particular table for a given id. If a record is found, a counter field on that record is incremented by one. If the given id is not found, a new record is inserted into that table. This is the common UPSERT scenario. I want to be able to do this in a busy environment and so the stored procedure has to co- operate and play nicely with other concurrent processes. The Setup. The set up has two parts. SQL EXISTS operator checks the existence of a result of a subquery. Also discussed SQL Exists with group by, SQL Exists with IN, SQL NOT Exists with description. I'm comparing different methods of writing an insert/update stored procedure that will perform well concurrently. The first part is the table and stored procedure. The stored procedure will change for each method, but here’s the setup script that creates the test database and test table: /* Setup */if. DB. That’s not too hard. Here’s the c- sharp program I came up with: Program. It compiles into a command line program that calls a stored procedure 1. It calls the stored procedure 1. This should generate 1 insert and 9 updates for each record. The INSERT INTO SELECT statement is used to add multiple new records into a database table at one time. Method 1: Vanilla. The straight- forward control stored procedure, it simply looks like this: /* First shot */if. OBJECT! Not too bad. The good news is that this was my control scenario and now I’m confident that there is a valid concurrency concern here. And that my test application is working well. Method 2: Decreased Isolation Level. Just use NOLOCKS on everything and all your concurrency problems are solved right? OBJECT. These primary key errors occur on 0. NOLOCK = NOHELP in this case. Method 3: Increased Isolation Level. So let’s try to increase the isolation level. The hope is that the more pessimistic the database is, the more locks will be taken and held as they’re needed preventing these primary key violations: if. OBJECT! Something went wrong and while there are no primary key violations, 8. A bit of digging tells me that several processes have gained shared locks and are also trying to convert them into exclusive locks? A bit of research on Stackoverflow. Sam Saffron called Insert or Update Pattern For SQL Server. He describes what I’m trying to do perfectly. The idea is that when the stored procedure first reads from the table, it should grab and hold a lock that is incompatible with other locks of the same type for the duration of the transaction. That way, no shared locks need to be converted to exclusive locks. So I do that with a locking hint.: if. OBJECT! The world makes sense. It always pays to understand a thing and develop a plan rather than trial and error. Method 5: Read Committed Snapshot Isolation. I heard somewhere recently that I could turn on Read Committed Snapshot Isolation. It’s an isolation level where readers don’t block writers and writers don’t block readers by using row versioning (I like to think of it as Oracle mode). I heard I could turn this setting on quickly and most concurrency problems would go away. Well it’s worth a shot: ALTERDATABASE Upsert. Test. Database. SET ALLOW! Primary key violations all over the place. Even more than the control! And by the way, if I try this with Snapshot Isolation, I not only get PK violations, I get errors reporting “Snapshot isolation transaction aborted due to update conflict”. However, combining method 4 with snapshot isolation once again gives no errors. Kudos to Method 4! Other Methods. Here are some other things to try (but I haven’t): Avoiding concurrency issues by using Service Broker. If it’s feasible, just queue up these messages and apply them one at a time. No fuss. Rewrite the query above as: UPDATE. The status quo is not going to cut it here. Strict locking that is used with the SERIALIZABLE isolation level doesn’t seem to be enough! While this would work, the architectural changes are pretty daunting Update! Other Methods: MERGE statement. Busted. See comments section. Update! 2. 3, 2. 01. Other Methods: MERGE statement + Increased Isolation. Confirmed. With a huge number of comments suggesting this method (my preferred method), I thought I’d include it here to avoid any further confusion. Don’t try to apply these conclusions blindly to other situations. In another set of circumstances who knows what the results would be. But test for yourself. Like a good friend of mine likes to say: “Just try it!”So that’s the show. If you have a myth you want busted. Drop me a line, or leave me a message in the comments section. Cheers ’til next time.

Reasons why the HDPE Blow Molding Industry is using Calcium Carbonate. When maintaining bottle weight, wall thickness is reduced, generally reducing crushing strength under top load while the drop impact strength is typically unchanged or slightly reduced. The bottle’s neck finish dimensions and bottle volume are maintained. In this one of many case studies, 1. Boston round bottles were consistently made to 3. Co- HDPE (0. 3. MI / 0. These results represent the effects of Omyacarb. Environmental stress cracking is the number one cause of failure for many containers molded from HDPE polymer, even with mild chemicals. Chemical agents, by diffusion, can accelerate the extension of cracks through a polymer under stress. Calcium carbonate and its effects on morphology blocks this crack propagation, creates a longer (torturous) path for crack growth, and thus can greatly prolong the time until failure. 6 MATERIAL SELECTION & ENVIRONMENTAL STRESS CRACK RESISTANCE (ESCR) TESTING It is important to fully define the application requirements and environment in order to. FOR IMMEDIATE RELEASE Florida DOT Approves Use Of Polypropylene Pipe ADS HP Polypropylene Pipe Meets Specification for 100-Year Design Life in Side Drain, Cross Drain. The relatively finer sized Omyacarb. The higher particle count (more particles) of Omyacarb. This means further delay of ESC- failure and extended useful bottle life. Reduced Cycle Time. Calcium carbonate allows a reduction of overall cycle time of roughly 1% for each 1% of mineral added by way of reduced cooling (blow) time. At higher loadings the cycle can be reduced by up to 2% for each 1% mineral. The main reason for this effect is the much higher thermal conductivity of calcium carbonate, as compared to the polymer. HMA 035 is a UV stabilized HDPE grade, characterized by excellent dimensional stability, very high stiffness and good impact strength. 10/15 HB5502B Formolene® High Density Polyethylene (HDPE) Resin Designed for Blow Molding Applications Formolene® HB5502B is designed for applications requiring. ExxonMobil’s extensive portfolio of high density polyethylene (HDPE) resins combine toughness and stiffness with resistance to environmental stress cracking. United States Plastic Corporation distributes industrial and commercial plastic products such as tanks, barrels, buckets, bags, tubing, plastic sheet, pvc pipe. Reasons why the HDPE Blow Molding Industry is using Calcium Carbonate. The brighter colors in the image (above left) indicate higher temperatures for the typical “Control” bottle without calcium carbonate. Incorporating 7% of Omyacarb. This reduction in post- mold bottle temperature allows a reduction of cooling time (blow time) until the bottle comes out of the mold at the same temperature as the Control, before adding calcium carbonate. In this case, the blow time was reduced by ~9%, an overall cycle time reduction of 6. Incorporation of ~1. Enviroseal are one of the leaders in Geomembrane Installation in the UK and in Europe. Geomembrane lining systems have been around for over 50 years. High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a polyethylene thermoplastic made from petroleum. It is sometimes called "alkathene" or. Omyacarb. The bottle wall thickness was as expected. A slightly reduced wall thickness comes from increasing levels of calcium carbonate, while holding the bottle weight constant. The measured values were as predicted by calculation. Drop Impact Resistance. Drop impact performance remained the same within experimental error, despite the reduced wall thickness of the bottles containing calcium carbonate. All bottles passed the normal (Bruceton stair step) single drop method, each surviving a single 1. In order to produce failures for comparison purposes, each bottle was dropped repeatedly at increasing heights until the accumulated multi- drop abuse created a leak failure. The containers resisted about 5. Environmental Stress Crack Resistance Hdpe PropertiesThe Crush Resistance for the recommended range of up to 5. HDPE- homopolymer and up to 8% for HDPE- Copolymer is only slightly reduced. Because all of the bottles were made to the same target weight, the bottles containing calcium carbonate (of higher specific gravity) had slightly reduced sidewall thickness, which is responsible for reduced crushing strength. The reduction in strength is due to the reduced wall thickness, not the calcium carbonate. This also highlights the natural advantage of material savings, due to both reducing wall thickness and the partial replacement of HDPE resin by calcium carbonate. Omya recommends that fitness for use testing be performed for containers of customer- specific size, shape and material, in order to determine the actual effects of incorporating calcium carbonate on all physical properties of interest. Plastic bottle - Wikipedia. A water bottle. Worldwide, 4. Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo, milk, and ink. The size ranges from very small sample bottles to large carboys. History. Except for wine and beer, the food industry has almost completely replaced glass bottles with plastic bottles.. Production. The choice of material varies depending upon application. This material is economical, impact resistant, and provides a good moisture barrier. HDPE is compatible with a wide range of products including acids and caustics but is not compatible with solvents. It is supplied in FDA- approved food grade. HDPE is naturally translucent and flexible. The addition of color will make HDPE opaque, but not glossy. HDPE lends itself to silk screen decoration. While HDPE provides good protection at below freezing temperatures, it cannot be used with products filled above 1. It is less rigid and generally less chemically resistant than HDPE, but is more translucent. LDPE is used primarily for squeeze applications. Environmental Stress Crack Resistance Hdpe PipeLDPE is significantly more expensive than HDPE. Polyethylene terephthalate (PET, PETE or polyester) is commonly used for carbonated beverage, water bottles and many food products. PET provides very good alcohol and essential oil barrier properties, generally good chemical resistance (although acetones and ketones will attack PET) and a high degree of impact resistance and tensile strength. The orienting process serves to improve gas and moisture barrier properties and impact strength. This material does not provide resistance to very high temperature applications—max. It provides an excellent barrier to most gases and its drop impact resistance is also very good. This material is chemically resistant, but it is vulnerable to some solvents. PVC has poor resistance to high temperatures and will distort at 1. It has attained notoriety in recent years due to potential health risks. Polycarbonate (PC) is a clear plastic used to make water and milk bottles. PC bottles. Polypropylene (PP) is used primarily for jars and closures and provides a rigid package with excellent moisture barrier. One major advantage of polypropylene is its stability at high temperatures, up to 2. Polypropylene is autoclavable and offers the potential for steam sterilization. The compatibility of PP with high filling temperatures is responsible for its use with hot fill products. PP has excellent chemical resistance, but provides poor impact resistance in cold temperatures. Polystyrene (PS) offers excellent clarity and stiffness at an economical cost. It is commonly used with dry products including vitamins, petroleum jellies, and spices. Styrene does not provide good barrier properties, and exhibits poor impact resistance. Fluorine- treated HDPE bottles are exposed to fluorine gas in a secondary operation, are similar in appearance to HDPE and have exceptional barrier properties to hydrocarbons and aromatic solvents. Fluorine treated bottles are excellent for use with insecticides, pesticides, herbicides, photographic chemicals, agricultural chemicals, household and industrial cleaners, electronic chemicals, medical cleaners and solvents, citrus products, d- limonene, flavors, fragrances, essential oils, surfactants, polishes, additives, graffiti cleaning products, pre- emergents, stone and tile care products, waxes, paint thinner, gasoline, biodiesel, xylene, acetone, kerosene and more. For non- bottle applications, fluorination of plastic can provide compliance with state and federal regulations. An example would be fluorinated plastic fuel tanks used for lawn and garden equipment, automobiles, etc. Post- consumer resin (PCR) is a blend of reclaimed natural HDPE (primarily from milk and water containers) and virgin resin. The recycled material is cleaned, ground and recompounded into uniform pellets along with prime virgin material especially designed to build up environmental stress crack resistance. PCR has no odor but exhibits a slight yellow tint in its natural state. This tint can be hidden by the addition of color. PCR is easily processed and inexpensive. However, it cannot come into direct contact with food or pharmaceutical products. PCR can be produced in a variety of recycled content percentages up to 1. K- Resin (SBC) is ideally suited to a wide variety of packaging applications by virtue of its sparkling clarity, high gloss, and impact resistance. K- Resin, a styrene derivative, is easily processed on polyethylene equipment. It is suitable for packaging many products but is specifically incompatible with fats and unsaturated oils or solvents. This material is frequently used for display and point- of- purchase packaging. Bioplastic - polymer structures based on processed biological materials rather than petrochemicals. Bioplastics are commonly made from renewable sources like starch, vegetable oil, and less commonly, chicken feathers.
