Users can hide the number of likes on Facebook On May 27, Facebook officially announced the launch of the feature to hide the number of likes on Facebook and Instagram. Users can optionally hide the public like count on posts. Accordingly, this social network will offer an option to hide the number of likes on all posts on the news feed. Users can also choose to hide the number of likes on their own posts so that others can’t see how many likes that post has. According to Facebook, with this feature, people can focus on the shared image or video instead of the number of likes. Users can hide the number of likes on other people’s posts, by accessing the new “Posts” section in the “Settings” section. This control applies to all News Feed posts. Besides, users can also choose to hide the number of likes before sharing a content. The feature can be optionally enabled/disabled, even after the content has been posted. Because everyone wants more flexibility, we’ve made the choice so they can adjust as they please. Over the next few weeks, both of these controls will be in place, according to Facebook. Previously, this feature was tested on Instagram recently to find out if hiding the number of likes reduces the user experience or not. Many users and experts say that not seeing the number of likes is beneficial for some, but annoying for others, especially in the context that people base their likes on the number of likes. to gauge the popularity and popularity of a content. Therefore, this feature will be offered as an option so that users can decide which option is right for them. Facebook says it’s working to discover more ways for people to have more control over their experience. That’s why the largest social network on the planet is launching new tools to let people filter objectionable content from Direct Messages and offer features to control what they see. and share on Facebook News Feed- like the News Feed Filter Toolbar, Favorites and Adjust who can comment… Changing the way people see like counts is a big change. Facebook and Instagram will continue to work on new ways to give people more choice and feel good about the time spent in apps.

Share information about which type of collagen is good, experts say. Currently, collagen is divided into many different forms. In particular, each type of collagen has its own advantages and disadvantages. Accordingly, depending on the purpose, or the need to use collagen, you will choose the best type of collagen. Illustration On the market today collagen is also divided into forms such as collagen powder, collagen tablets, collagen oral form. Specifically, the advantages and disadvantages of each type are as follows: Collagen powder Powdered collagen is a new type of collagen that has recently appeared in the Vietnamese market. Trusted by many women. With powdered collagen, the biggest advantage is not only in efficiency. And this type of collagen also ensures high safety for users. Moreover, users can use powdered collagen to mix with fruit juices. To enhance the efficiency of use without affecting the quality and taste of the product. However, compared to liquid collagen and tablets, powdered collagen has the disadvantage that it is more difficult to buy in the market. Water-based collagen Water-based collagen is sought after by many women today. Liquid collagen has advantages such as higher absorption than tablets and powders. Liquid collagen is widely sold in the market, also easier to find because of its mass. However, this type of collagen also has some disadvantages such as: High cost, difficult to drink and difficult to store. Collagen tablets Collagen tablets appear quite a lot on the Vietnamese market. Rated as the easier to drink of the 3 types of collagen and can be carried anywhere, the price is relatively cheaper. Although chosen by many women, this type of collagen still suffers from some disadvantages such as: Lower efficiency in collagen types. Because, when supplementing with collagen in the form of tablets, it takes time to dissolve, so the effect will be longer and slower. However, depending on the preferences and desires of each individual, you can actively choose your own type. Illustration It can be said with the above analysis. Surely readers can find the answer to the question: “Which type of collagen is good?” At the same time, it is possible to choose the type of collagen that is suitable for the body, for the best effect.

Flooring can be grouped on the market into two main types: Natural wood flooring and laminate flooring. Types of flooring have many different origins, from domestic production to imports from European countries (Germany, Sweden…), in Southeast Asia (Thailand, Malaysia…) and most are boards. Wood flooring originated in China. The price of natural wood flooring is getting higher and higher due to the scarcity of raw materials and the inevitable trend of using laminate flooring. Wooden floors have many advantages such as clean, close, warm, convenient construction. For natural wood flooring selection, you can view a few random bars in the shipment to evaluate the product. Natural wood flooring products are good for flat, matte surfaces with few wood eyes; the edges are not chipped, scratched, the bar has no cracks…; Try to put the bars together and see that it fits your hand, not too tight and not too loose. In addition, some bars can be laid out on a flat surface to evaluate the uniformity of wood grain and color. Natural wood is harvested from many different sources of raw materials, so it is easy for different finished products (even though they are the same type of wood). If the user wants to use natural wood for a large and solid surface, this factor should be carefully considered to have a uniform surface finish. With industrial wood, there are many models on the market, so it is difficult to choose. Basically, the way to distinguish is not the same as for natural wood because laminate flooring is “one hundred bars like one”; It is important to know the origin. Quality-assured laminate flooring often has the brand name imprinted on the underside, and has the words “Made in… (name of country)” (eg Made in Germany), the print is clear and sharp. Laminate flooring has different technical characteristics related to cost. For example, if you choose a wooden floor for public spaces such as restaurants, supermarkets, etc., then choose a floor with high scratch resistance and roughness (to meet the needs of walking on shoes with frequency of travel). much). Appropriate spaces for use are usually indicated on the product’s packaging. It is necessary to check whether the edges of the bars are easily chipped or not. It is necessary to preview the price of the distribution company (if any) and consult the prices of several agents on a product to avoid buying at an unreasonable and expensive price. Besides, it is possible to mention some flooring materials that have the same functions, properties, specifications and construction process as wooden floors but with other materials such as bamboo floors, composite plastic floors. These types have the same common features as wooden floors but are manufactured with different materials, have different surface and grain forms and have different physical and mechanical properties. For example, bamboo flooring has a fairly high hardness, water-resistant plastic floors can be used for paving balconies, loggias, patios… These types of materials can replace wooden floors in each specific situation to exploit. exploit the optimum properties of the material. Using wooden floors in the interior space There are two basic ways to coordinate floor colors with furniture, that is, similarity and contrast. Basically, wooden floors are very similar to the interior space of houses, in addition to the preeminent features of functions such as cleanliness, proximity, warmth, convenient construction… However, it should be noted. some points for proper and effective use. Wood floors are generally not recommended for use on the ground floor because they are very susceptible to moisture, deformation and damage, as well as being easily penetrated by insects. The kitchen area should also not be used because it is easy to have water, as well as fire, which are unfavorable factors for wooden floors. Wooden floors are suitable for use in spaces such as living rooms, bedrooms, floor halls, hallways, etc., with little negative impact in daily life. The attic should also not use wooden floors because usually this floor is rarely used for living, is subject to hot sun, can be flooded with water, rain … Wooden floors can be suitable for both modern and classic architectural – interior spaces. However, it is necessary to pay attention to interior colors (wall paint, ceiling, curtains, furniture, etc.) to choose the appropriate type/color. If using natural wood, each type of wood has its own color. For example, iron floors have dark colors, pomu floors have light colors… Industrial floors have more diverse colors and wood grain elements, the color is only a part of the aesthetic, it does not determine the quality of the flooring. There are two basic ways to match the floor color with furniture, that is, similarity and contrast. With a similar arrangement, choose wood floors and furniture of the same color (maybe a little lighter than each other); In contrast, you can use dark floors, light furniture or vice versa (light floors, dark solid furniture). It is necessary to avoid dark floors and dark furniture because it will darken the space and not honor the furniture in the space. Many laminate flooring companies advertise super water resistant laminate floors. However, it should be understood that “water resistant” here is within a certain limit, but wooden floors – whatever it is, cannot be as water-resistant as ceramic tiles or natural stone. In order not to be dazzled by the “forest” of products on the market Wooden floor “hundreds of flowers bloom” on the market of building materials. Therefore, to choose real wood flooring is not easy either. Customers should actively seek out reputable companies and suppliers with good warranty regime to search and choose products. With laminate flooring, quality is paramount. In addition to choosing the type of flooring to ensure quality, choosing the model (specification, pattern, color …) also makes sense. To have a beautiful interior space, it is necessary to have a professional eye and an expert voice for advice. When looking at the store, you can see a lot of beautiful models, but it is not certain that the model “goes” into the house, into the interior space is appropriate (and vice versa). The factors that need to be referenced and dominated are: interior style, floor plan, interior layout, style – color of furniture details, lighting conditions, etc. Usually these factors come before and decide. suitable floor pattern. Ideally, please provide the information and needs as mentioned above to architects and consultants to assist them in choosing the right flooring model. And do not let the sales people advise because they will lead with their purpose of selling the type of product they need to consume, rather than doing good for their home, and practically expert in wood flooring and professional expertise. Design is completely different.

(China Business News) The British government cuts 95% of aid to China, leaving 900,000 pounds Recently, British Foreign Minister Raab announced that in this fiscal year’s official development assistance funds, aid to China will be cut by 95%, leaving less than 1 million pounds. The Conservative Government has boldly stated that it will allocate 0.7% of the country’s income every year for international aid. According to the British “Mirror” report, due to the impact of the new crown natural disaster, the anti-epidemic “man-made disaster” and the economic shock of Brexit last year, this expenditure will be reduced to 0.5% this fiscal year. The US “Politician” News Network added that one-third of the UK’s official development assistance funds are still invested in the “Indo-Pacific” and South Asia. The aid funds to China will be cut by 95%, leaving 900,000 pounds (approximately 8.13 million yuan) to fund open society and human rights projects. Some netizens on Weibo ridiculed that the British aid is not as good as the one-year revenue of some Internet celebrity shops in Changsha. In July last year, the British Department of International Development announced that the British government directly and indirectly provided assistance to China of 71.6 million pounds in 2018.

Outdoor paving materials, necessarily anti-slip. In the design process, homeowners rarely pay attention to this issue, but only care about the functional needs, the form of the house. But to the construction stage – especially in the finishing stage; in connection with the procurement and use of materials; even though it is possible that a very clear and specific designation is given in the engineering design drawing; The owner still likes … to go to the material market to actually see, to choose materials for his house. The “conflict” between the designer and the owner about the choice and use of the material still occurs often. Architects have expertise and overview, choose the right materials; But sometimes the architect is too fond of his style, does not care to grasp the needs and psychology of the host. And the homeowner chooses materials according to the feelings, without the overall look. Many types of display materials are beautiful, but put into the work is not beautiful, or in particular a particular area is not suitable. In many cases, the materials are chosen by architects to beautify the house, but the owner is … warm and unsatisfied; and conversely, homeowners (arbitrarily) choose materials rarely in the opinion of architects. This is a professional job, but the new owner is the direct user of the project, related to those materials and the person… to spend money. Therefore, to have a common voice; then the architect must grasp, learn the needs, living habits and home psychology (with members); but the owner needs to listen to the advice of a specialist, avoid the type of “shopping” for the material, see something good, beautiful (at that time) and then pick up. The concept of beauty and the needs and aesthetic level of each person is different. Therefore, in order to choose the right materials and come to a common voice, in general, the experience of some architects is that – apart from the financial factor, it is necessary to adhere to some specialized principles. subject and each side also need to have an attitude of respect, “yield” to each other. Chandeliers are an important element in classical European architectural style. Suitable for use Materials used in architectural works, first of all, must be suitable for function; This is the most important principle. Each space, each function room, each type of structure and part of architecture has different positions and roles, it is necessary to have materials with suitable mechanical – physical – chemical properties. Floor tiles where water is available (courtyards, toilets) require slip resistance first, and then other issues such as patterns, colors …; garden and exterior materials must be resistant to natural conditions (rain, sun); materials and equipment in the bathroom must be water-resistant, high-moisture-resistant, and electrical safe; the cooking material must be heat resistant … Suitable for use space g Each space, each room in the house has its own specific function, for human activities living, living or working in it. In order to provide the correct functional effect, the materials need to be suitable as well. For example, the living room next to the garden on the ground floor needs airy, comfortable, close to nature, can use natural materials; Upstairs the common room provides closeness; the bedroom should be quiet and warm; music and entertainment rooms need an impression … In addition to the design in the functional space, the interior layout; Then the use of materials, equipment, materials in these spaces also contributes to creating the desired space. Suitable architectural style – interior Each house has an architectural style and interior, according to the will, needs of the owner with the advice of the architect; and designed in that direction by the architect. In order to create style, the role of the material and how it is used is very important. Each architectural – interior style requires the respective materials and the correct way of using them. Modern style has many new materials such as glass, steel, stainless steel …; Eastern classical style has a deep sound of brown wood with sophisticated details; The rustic folk style has the presence of natural materials such as bamboo, wood, stone … Natural stones, ceramic tiles, wood and trees create a rustic, close garden feel. Matching ratio Ratio is an important factor in architecture. Some spaces requiring use of materials are involved in this, especially tiled surfaces. The area of ​​a floor, the height of the walls, and the space of the room need the right proportions. The bathroom is usually small, so choose the moderate size ceramic tiles; should not be too big, if you calculate the parity the better. If using a large brick size, in addition to inconsistent proportions and visuals, it also causes wasteful damage due to much cutting. Some types of architectural parts are now pre-engineered with many sizes, for example, doors need to be based on the area, the height of the room, the space of the wall to choose the right size. Correlation in harmony with the surroundings A building is using many types of materials, in many spaces and spaces that are related to each other. In order to have a harmonious whole, this also needs to be noted. That relationship can be in itself in each function room, within the project; Or out in the garden, on the alley – the street. It is necessary to consider the relationship and surrounding landscape for material selection. For example, at present, there are many townhouses and apartments designed with living room space – living together with the kitchen – dining. The living room floor – common living room or parquet; and the tiled kitchen. These two materials have different origins, different properties coexist on the same ground; and so it is necessary to choose the appropriate species, which can “go together”. In general, the selection and use of materials are very important for architectural works. In a way, there is no such thing as a ugly or beautiful material. Bad or beautiful is whether it exists properly, in the right place in the project or not. Choosing the right materials, beautifying, correcting the space, the overall project. This requires both creativity, sophistication and designer’s experience; the harmony, the predestined relationship in the architect and the host’s relationship./.

Sharing information about what type of collagen is good experts said, currently collagen is divided into many different forms. In particular, each type of collagen has its own advantages and disadvantages. Accordingly, depending on the purpose and need of using collagen you will choose the best type of collagen. For example, if you want to take collagen to take care of your skin, then collagen types 1 and 3 are the best. However, if you want to improve the condition of bones, joints, eyes, … then collagen types 2, 4 will be suitable and give higher efficiency. Illustration Besides, in addition to type, collagen is now divided into forms such as powdered collagen, tablet collagen, oral collagen, … Specific advantages and disadvantages of each type such as: Powdered collagen Powdered collagen is a type of collagen that recently appeared in the Vietnamese market and is trusted by many women. With powdered collagen, the biggest advantage is not only about efficiency but this type of collagen also ensures high safety for users, limited preservatives compared to water and tablets. Moreover, users can use powdered collagen to blend with fruit juices to enhance efficiency without affecting the quality and taste of the product. However, compared to collagen in liquid and tablet forms, powdered collagen is more difficult to buy on the market and is often difficult to drink. Water-based collagen Although it is not preferred to use as much as powdered collagen, water-based collagen is still sought by many women today. Because the collagen line has outstanding advantages such as: High absorption and much sale in the market, it is easier to buy. However, this type of collagen also suffers some disadvantages such as: High cost, difficult to drink and difficult to preserve. Collagen tablets Collagen pellets appear quite a lot on the market and are considered to be the easiest to drink of the 3 types of collagen and can be carried anywhere, the price is relatively cheap. Despite being chosen by many women, this type of collagen still suffers some disadvantages such as: Its effectiveness is not as high as the two types of collagen above. Because, when supplementing the body in the form of collagen tablets, it takes time to dissolve, so the effect will be longer and slower. However, depending on the preferences and desires of each individual, you can actively choose your own type. Illustration 4 types of collagen selection women should hold firmly After understanding which type of collagen is good, in order for the process of using collagen to be highly effective, to ensure safety for the health of women, women need to pay attention to the information by Dr. Tran Thi Thanh Nho, a specialist doctor. Department of Dermatology II, Oriental General Hospital advises as follows: – Should choose collagen made from special fish from Norwegian cod to ensure 100% content. – If you want to be good for your skin, you should drink collagen type 1, because this type of collagen accounts for 80% of the skin. – It is best to choose hydrolyzed collagen because this type of collagen has a higher absorption capacity than normal collagen. Note, choose collagen that has 20 types of amino acids to be able to create a complete collagen molecule chain, shortening the process of collagen absorption into the body. – Take collagen regularly and with the right amount and combine with vitamin C to achieve higher efficiency.

Shrimp sauce is one of the typical dishes of Western people, never absent from simple and rustic meals. The typical taste of the western shrimp sauce is different from that of any other region. The sweetness of Bac Dat Mekong River shrimp together with the crispness of the western platypus has created an unforgettable taste. Fish sauce served with white rice, boiled meat, boiled vegetables, … or banh tet, banh chung, … creates a unique resonance, remembering it forever for the first time. Aunt Tu Co fish sauce was born from Aunt Tu Co’s passion for cooking with family members. I got up at 5 a.m. to go to the market to buy the live Bac Dat shrimp, and picked each papaya by hand. I did all the steps myself because she said: “ The papaya should be well-sliced, otherwise it won’t be crunchy. Fish sauce must soak at the right time or else there will be no meat left. ” This is a homemade dish that does not use borax, colorants or preservatives, but only contains memories of the countryside, the simple meals that gather with the family.

Edit | Tina Technology Radar is a technology trend report that ThoughtWorks releases every six months. It keeps track of how interesting technologies are developed, which we call items. The technology radar uses quadrants and rings to classify it. Different quadrants represent different types of technologies, and the rings represent our maturity assessment. After six months of tracking and precipitation, ThoughtWorks TAB (ThoughtWorks Technical Advisory Committee) produced the 24th technical radar for technicians based on our practice cases in multiple industries. Analyze more than one hundred technical items, explain their current maturity, and provide corresponding technical selection suggestions. 1 Four themes in this issue Platform team that accelerates product launch More and more organizations are adopting the concept of platform team to develop products, that is, setting up a dedicated team to create and support internal platform functions, and use these functions to accelerate application development, reduce the complexity of operation and maintenance, and shorten the time to market time. This increasingly mature approach is welcome, so as early as 2017, we introduced this technology to technology radar. But as maturity increases, we find that organizations should avoid using some anti-patterns when applying this technology. For example, “using one platform to rule everything” may not be the best choice. “Building a big platform in one step” may take several years to deliver value. In line with the original intention of “Once it is built, there will be people using it”, it may be a huge waste in the end. On the contrary, using product thinking helps to understand the services that each internal platform should provide based on the needs of product customers. But if the platform team is allowed to only solve the problems submitted in the technical support ticket system, then this approach will produce the old-fashioned operation and maintenance island team, and the corresponding disadvantages of demand priority imbalance, such as slow feedback and response, and Competing for scarce resources and other issues. In addition, we have also seen some new tools and integration models emerge to effectively divide teams and technologies. The convenience of integration overwhelms the single best solution We have seen corresponding developer-oriented tool integrations on many platforms (especially in the cloud field). For example, artifact libraries, source code control, CI/CD pipeline, wiki, and similar tools. Development teams usually manually select these tools and stitch them together as needed. Having a combined tool stack can bring more convenience and less work to developers, but this tool set rarely represents the best solution. Too complicated to get into the radar In the nomenclature of technical radar, the final state of the discussion of many complex topics will be “TCTB-too complex to enter the radar (too complex to blip)”. This means that those items cannot be categorized because they exhibit too many pros and cons, as well as a large number of nuances regarding suggestions, applicability of tools, and other reasons, which prevents us from summarizing them in just a few sentences. . These topics usually appear every year, including monorepos, distributed architecture orchestration guidelines, branch models, and so on. Like many topics in software development, there are too many trade-offs to provide clear advice. Identify the architectural coupling context In software architecture, how to determine an appropriate level of coupling between microservices, components, API gateways, integration centers, front-ends, etc. is a topic that is discussed in almost every meeting. It can be seen everywhere that when two pieces of software need to be connected together, architects and developers are struggling to find the right level of coupling. We need to spend time and energy to understand these factors, and then make these decisions according to local conditions, instead of hoping to find a general but inappropriate solution. 2 First look at some of the quadrant highlights Platform Engineering Product Team (Adopted) As pointed out in one of the topics of this issue of Radar, the industry has accumulated more and more experience in the “platform engineering product team” that creates and supports internal platforms. Teams in the organization use these platforms to accelerate application development, reduce operational complexity, and shorten time to market. As the adoption rate increases, we are becoming more and more aware of the good and bad patterns of this approach. When creating a platform, it is important to clearly define the customers and products that can benefit from it, rather than building it out of thin air. We not only have to beware of the layered platform team, it retains the existing technology islands, but is just labeled as the “platform team”, and we must also be careful about the work order-driven platform operation model. When considering how to best organize the platform team, we are still loyal supporters of the concept of team topology. We believe that the platform engineering product team is a standard method and an important enabler of high-performance IT. Cloud sandbox (experimental) As cloud services become more and more common, and creating cloud sandboxes becomes easier and can be applied on a large scale, our team is therefore more inclined to use a completely cloud-based (relatively local) development environment. Reduce maintenance complexity. We found that the tools used to simulate cloud-native services locally limited developers’ confidence in the build and test cycle, so we focused on standardized cloud sandboxes instead of running cloud-native components on development machines. This approach can better enforce the application of infrastructure as code practices, and provide developers with a good adaptation process in the sandbox environment. Of course, this shift is also risky, because it assumes that developers will be completely dependent on the availability of the cloud environment and may slow down the speed at which developers can get feedback. We strongly recommend that you adopt some lean governance practices to manage the standardization of these sandbox environments, especially in terms of security, access control, and regional deployment. Homomorphic encryption (evaluation) Complete homomorphic encryption (Homomorphic encryption) refers to a type of encryption method that allows direct calculation operations (such as search and arithmetic operations) on encrypted data. At the same time, the calculated result still exists in encrypted form, and can be decrypted and displayed later. Although the homomorphic encryption problem was raised as early as 1978, the solution did not appear until 2009. With the improvement of computer computing power and the emergence of easy-to-use open source libraries such as SEAL, Lattigo, HElib and partial homomorphic encryption in Python, the application of homomorphic encryption in real-world applications has truly become feasible. Those exciting application scenarios include privacy protection when outsourcing computing to an untrusted third party, such as computing encrypted data in the cloud, or enabling a third party to aggregate the intermediate results of homomorphic encrypted federal machine learning . In addition, most homomorphic encryption schemes are considered safe for quantum computers, and efforts to standardize homomorphic encryption are also underway. Although homomorphic encryption currently has many limitations in terms of performance and supported computing types, it is still a technology worthy of our attention. Sentry (adopted) Sentry has become the default option for many teams. Sentry provides some convenient functions, such as error grouping and using appropriate parameters to define error filtering rules, which can greatly help deal with a large number of errors from end-user devices. By integrating Sentry into the continuous delivery pipeline, you can upload source code mapping files to debug errors more efficiently, and it is easy to trace which version of the software produced these errors. We appreciate that although Sentry is a SaaS product, its source code is public, so it can be used for free in some smaller use cases and self-hosting. imgcook (evaluation) imgcook is a software as a service product under Alibaba. It can generate front-end code from different types of visual drafts (Sketch/PSD/static pictures) with one click through intelligent technology. imgcook can generate static code. If you define a domain-specific language, it can also generate data binding module code. The technology has not yet reached the perfect level. Designers need to refer to certain specifications to improve the accuracy of code generation (hereafter The adjustment of the developer is still needed). We have always been very cautious about magic code generation, because in the long run, the generated code is usually difficult to maintain, and imgcook is no exception. But if you limit it to a specific context, such as a one-time event advertising page, this technique is worth a try. AWS CodePipeline (suspended) Based on the experience of multiple ThoughtWorks teams, we recommend that you use AWS CodePipeline with caution. Specifically, we found that once the team’s needs go beyond the scope of a simple pipeline, this tool becomes difficult to use. Although the first time you use AWS, it seems like you won a “quick victory”, but we suggest you take a step back and evaluate whether AWS CodePipeline can meet your long-term needs, such as the fan-out and fan-in of the pipeline, or more complicated Deployment, and test scenarios with special dependencies and trigger conditions. Snowflake (experimental) Since Snowflake was mentioned on the radar last time, we have gained more experience in its use and data mesh as an alternative to data warehouses and data lakes. Snowflake continues to impress people in terms of time travel, zero-copy cloning, data sharing and its application market. Snowflake has not appeared in any place that we dislike, so our consultants prefer to use it compared to other options. Amazon’s data warehouse product Redshift is moving in the direction of separating storage and computing, and this has always been Snowflake’s strengths. If you use the Spectrum feature in the Redshift product for data analysis, you will feel that it is not so convenient and flexible, partly because it is constrained by Postgres (although we also like to use Postgres). Federated queries may be the reason for using Redshift. In terms of operation, Snowflake’s operation will be simpler. Although BigQuery is another option and very easy to operate, Snowflake is a better choice in a multi-cloud scenario. We have successfully used Snowflake on GCP, AWS and Azure. Feature Store (evaluation) Feature Store is a data platform for machine learning, which can solve some of the key problems we currently encounter in feature engineering. It provides three basic functions: (1) Use managed data pipelines to eliminate conflicts between new data and data pipelines; (2) Catalog and store feature data to promote the discoverability of features across models And synergy; (3) Continuously provide characteristic data during model training and interference. Since Uber disclosed the Michelangelo platform, many organizations and start-ups have established their own signature libraries; such as Hopsworks, Feast, and Tecton. We see the potential of Feature Store and recommend careful evaluation. Self-developed infrastructure as code (IaC) products (suspended) Those products supported by the company or the community (at least in the industry) are constantly evolving. But sometimes organizations tend to build frameworks or abstractions on top of existing external products to meet very specific needs within the organization, and believe that this adaptation will have more benefits than their existing external products. We found that some organizations tried to create self-developed infrastructure as code (IaC) products based on existing external products. They underestimated the amount of work required to continuously evolve these self-developed solutions based on their needs. Soon they will realize that the original version of the external product on which it is based is much better than their own product. In some cases, the abstraction built on the external product even weakens the original function of the external product. Although we have witnessed some successful cases of organizing self-developed products, we still recommend that this approach be carefully considered. Because this will bring a workload that cannot be ignored, and a long-term product vision needs to be established in order to achieve the desired results. Combine (adopted) We moved ReactiveX (a series of reactive programming open source frameworks) a few years ago to the “adoption” ring of the technology radar. In 2017, we mentioned RxSwift, which can apply reactive programming to Swift-based iOS development. Since then, Apple has launched its own reactive programming framework in the form of Combine. For apps that only support iOS 13 and later, Combine has become the default choice. It is easier to learn than RxSwift and integrates well with SwiftUI. If you want to convert an existing project framework from RxSwift to Combine, or use both in a project, you can learn about RxCombine. Kotlin Flow (experimental) The introduction of Kotlin coroutines opened a door to Kotlin’s innovation-Kotlin Flow, which is directly integrated into the coroutine library, is one of them. Kotlin Flow is an implementation of responsive flow based on coroutines. Unlike RxJava, stream is a Kotlin native API, similar to the familiar sequence API, including map and filter methods. Like sequences, streams are “cold”, which means that the values ​​of the sequence are constructed only when needed. All these features make the writing of multi-threaded code easier and easier to understand than other methods. It is foreseeable that converting a stream into a list through the toList method will become a common pattern in testing. River (evaluation) The core of many machine learning methods is to create a model from a set of training data. Once the model is created, it can be used repeatedly. However, the world is not static, and usually models need to change with the emergence of new data. Simply retraining the model can be very slow and expensive. Incremental learning solves this problem, it makes it possible to learn incrementally from the data stream, thereby reacting to changes more quickly. As an added benefit, computing and memory requirements are lower and predictable. We have accumulated good experience in the implementation based on the River framework, but so far, we need to add verification after the model is updated, sometimes manually.

After the valuation of A shares has risen sharply, in 2021, Hong Kong stocks in the moderate valuation area will be favored by funds from the south. It is reported that Dacheng Hong Kong Stock Selected Mixed Fund (QDII) (code: Class A 011583, Class C 011584) under Dacheng Fund has been put on sale on April 15. This fund is personally helmed by Bo Yang, the director of Dacheng International Business Department and the research director of Dacheng Fund’s cross-border team. Bo Yang has lived in Hong Kong for 22 years, managed cross-border assets of more than 10 billion Hong Kong dollars, and has invested in Hong Kong stocks for more than 10 years. He is very close to the Hong Kong stock market and is familiar with global liquidity. Bo Yang had academic experience. After graduating from the Junior Class of the University of Science and Technology of China, he was the youngest assistant professor at the Business School of the University of Hong Kong. Later, he moved to the financial market and became the youngest Asia-Pacific and emerging market strategist at Morgan Stanley. Bo Yang’s investment framework is a combination of top-down and bottom-up. It has a global perspective, is good at asset allocation and selected individual stocks. It has previously won the Overseas Golden Bull Award twice (awarding institution: China Securities Journal; time: 2018 August 3, 2019, December 27).

22 years of residence in Hong Kong in the first round of public offerings

Bo Yang, Director of International Business Department of Dacheng Fund and Research Director of Dacheng Fund’s Cross-border Team. Born in the Junior Class of the University of Science and Technology of China, PhD in Finance from the University of Hong Kong, with more than 10 years of experience in Hong Kong stock investment management, he has won the China Securities Journal’s second and third overseas fund golden bull awards for two consecutive years.

According to the data, Bo Yang joined Dacheng Fund in 2015, and since March 2018, he has served as the investment manager of the first batch of Southbound Stock Connect commissioned portfolios of the National Social Security Fund. Prior to this, he has been in contact with institutional investors that dominate the Hong Kong market for a long time during more than 20 years of cross-industry experience in academia, research, and investment, including large global sovereign funds, large foreign long position funds, hedge funds, and Chinese and domestic investors. He has a strong grasp of his style preference; at the same time, he has a deep understanding of global liquidity and plays an important role in investing in Hong Kong, a capital market where the currency is directly linked to the US dollar.

As Bai Yang said, in the Hong Kong stock market, “the one who does not seek the overall situation is not enough to seek a domain.” Only from the forest of global assets can we see the specific tree of Hong Kong stocks clearly.

At present, Bo Yang manages a number of cross-border special account products, with a total asset scale of more than 10 billion yuan, of which the equity product management scale is about 5 billion yuan, which is mainly invested in Hong Kong stocks.

Deeply research individual stocks and focus on risks

Markets often underreact to the beginning of long-term structural changes and overreact to short-term events. Relying on the long-term market strategy research experience of top investment banks, Bo Yang is good at accurately grasping the direction in the early stage of major macro-trends, and capturing the drift of market winds and the formation of large-scale investment themes. Different from the mainstream of the market, Bo Yang’s stock selection is based on top-down, and the investment style remains open. It does not exclude any asset in growth, value, or cycle, nor is it limited to one or certain industries. The existing management investment targets range from the “old economy” to the “new economy”, from consumption, finance, real estate to health care, and information technology, covering all industries in the entire market.

Bo Yang believes that investment should maintain an open mind, not set limits on oneself, and not antagonize growth and value. For long-term management institutions (including social security funds) special accounts, Bo Yang’s investment style is a bit of an absolute return style, so he attaches great importance to risk control and dislikes large drawdowns, because drawdowns are directly related to the speed of returning to net worth. Bo Yang emphasized: Going air is not a risk, but losing money is!

Bo Yang Investment is mainly held in the medium and long term. Only in a few extreme cases will significant position adjustments and style switching be carried out. Bai Yang believes,

Accurately grasp the market trend, dare to grasp the turning point and concentrate on trading

Bo Yang’s investment framework is a combination of top-down and bottom-up, and tends to be top-down: judge the status quo of macroeconomic and monetary and fiscal policies, and then observe the expectations of the capital market, valuations, and valuations of various sectors , Earnings growth rate, selection of countries, regions and industries with the best price/performance ratio, and finally stock selection based on in-depth bottom-up individual stock research. There are more choices of industries and styles, and fewer choices. There are exceptions only when the market is in extreme valuation and sentiment situations. This is consistent with the results of the academic analysis of fund performance, that is, the vast majority of investment returns come from asset allocation, followed by stock selection, and very few come from timing. The difference between a top-down investment framework and a purely bottom-up framework is that the former can simultaneously obtain the benefits of style selection and sector rotation in asset allocation.

Bai Yang said that if he judges that the market valuation level or style rotation is close to an important turning point, he will do long and concentrated transactions. In addition, his investment is mainly based on steady and slow substitution, and the overall annual turnover rate of the investment portfolio is not high.

He believes that benefiting from the dual changes in the size and structure of Hong Kong stocks and the valuation of Hong Kong stocks dragged down by the global epidemic last year, Hong Kong stocks will most likely outperform A shares in 2021. In terms of volume, Hong Kong stocks have been active in IPOs, and their volume has continued to increase. At present, it is almost half the value of the A stock market, and has ranked among the top three in total global IPO value for two consecutive years. Structurally, due to the differences in the listing rules between Hong Kong and the Mainland, the Hong Kong stock market has gathered a large number of extremely dynamic TMT and biomedical companies. He believes that Hong Kong stocks are very likely to become the Chinese version of Nasdaq in the future. According to the GICS industry classification, the proportion of the “new economy” component of the Hong Kong stock Hang Seng Index in the total market value has increased from 16% five years ago to 39% at present. In addition, Hong Kong stocks have recently benefited from the return of China’s concept stocks, looking high.

In terms of general allocation, he pays attention to “three U assets” (Under-loved, Under-owned and Undervalued), that is, stocks that people don’t like, are seldom held by institutional investors, and are deeply undervalued. He believes that this type of There are good medium and long-term investment opportunities hidden in stocks.
