Scaling and Monitoring Cookie Run: Kingdom with Datadog

Datadog Monitors Cookie Run: Kingdom

Cookie Run: Kingdom is a mobile game that lets players build their own fantasy kingdom. The game is a spinoff of the Cookie Run series and was released in 2022.

Devsisters needed visibility into the health of their cloud-native applications, but their existing tools added complexity that made it difficult to pinpoint user-facing issues.

How Devsisters Scaled Their Game

Devsisters knew they had to build great experiences for a growing user base and improve speed to market. But the existing tools they used added complexity that made it difficult to get critical visibility into user-facing issues.

Cookie Run: Kingdom is the latest game in the Cookie Run series and the company’s most popular game to date with 8 million monthly active users (MUA). The team at Devsisters wanted to develop a RPG city-simulation game that integrated well with their existing OvenBreak and Cookie Run games but also captivated new audiences with its unique gameplay.

At peak traffic times, the game processes 2x its normal transaction rate — up to 60,000 transactions per second. The team needed a database that could keep up with this demand without sacrificing performance. Devsisters chose CockroachDB because it was built to scale automatically and easily. This means the team can spend less time monitoring their infrastructure and more time innovating on their product.

Devsisters Needed a Monitoring Solution

Devsisters had released other games based on the Cookie Run IP, but the breakaway success of Kingdom brought with it a heavier transactional workload than previous titles. With a variety of different metrics to track, the team needed a solution that could scale to their growing user base and keep pace with the game’s performance.

You agree that Devsisters has the right to monitor your use of the Service at any time and in its sole discretion, to determine whether you are complying with the Terms of Service, including any other Devsisters policies. You grant Devsisters a non-exclusive, royalty-free, irrevocable, perpetual license to use your name and likeness in any User Content that you post on or through the Service.

With Datadog’s turn-key integrations and support for a wide range of dynamic and ephemeral systems, the team was able to reduce their monitoring complexity and spend more time focused on problem detection. They now watch for sudden spikes in concurrent users or coins per user, which often indicate that a player is hacking the system to gain an unfair advantage.

Devsisters Switched to Play Asset Delivery

Devsisters is a mobile game studio that produces casual games for users worldwide. Their popular Cookie Run series includes running arcade games like Cookie Run: OvenBreak and social RPGs such as Cookie Run: Kingdom. These titles generate a large amount of data, leading to high CDN costs.

In order to reduce costs, Devsisters started to use Play Asset Delivery, which allowed them to package up to 1GB of assets with the first time user download. This helped them reduce the CDN cost and improve first-time player experience without sacrificing performance.

In addition to providing a great gaming experience, Cookie Run: Kingdom also allows players to obtain free rewards with special coupon codes. These codes can be redeemed on the game’s official website or via instant messaging services such as KakaoTalk and LINE. Redeeming these codes is quick and easy. Once redeemed, the codes will automatically be applied to your account.

Devsisters Leveraged Datadog

Devsisters chose Datadog because of its flexibility and ease of use, along with built-in support for dynamic and ephemeral systems. The company also appreciated Datadog’s turn-key integrations that enabled them to monitor their entire tech stack on a single platform.

With a single, unified view of their entire application stack, the Devsisters team could easily spot issues and make operational changes to ensure that their game was always up and running for players. They were able to spend less time focusing on manual monitoring and more time iterating on their game.

Datadog’s comprehensive observability platform is designed to help teams like the Devsisters foster a culture of collaboration and accelerated development by providing all the tools they need in one place. From infrastructure metrics, logs and network performance to APM, serverless and continuous monitoring and more, we’re here to support every step of the DevOps journey.

Unlocking Global Sports: Mastering Translation for TV Broadcasts

How to Translate to English For Million TV Sports Broadcast

Translating into English is a critical skill that can help you communicate with people from different cultures and languages. However, there are some things to keep in mind when translating. First, you must use a reliable translation tool that uses correct grammar and is culturally sensitive.

The word “translate” means to change something from one form to another. For example, you might translate a play into a movie.

Streaming Korean content with multi-language subtitles: The Alternative to K-Drama and Movies Anytime, Anywhere.

Kok TV – Watch K-Dramas and Movies Anytime, Anywhere

Kok TV is a Singaporean actress and businesswoman. She has starred in many television series and is regarded as one of the top ah jie in her native country of Singapore. Kok’s newest project is the new 130-episode drama What’s Wrong Doctor?. She plays a head nurse in this new show. 골스 레이커스


The surging popularity of Korean culture, including K-drama and music, has spawned an entire genre of online streaming services. These platforms offer access to a variety of Korean content within hours of broadcast. Unlike other Korean TV streaming services, Kocowa has an international team of translators that ensure programs are available to the public in high quality as soon as they air in Korea.

The service is free and ad-supported, but subscribers can also pay $4.99 per month for an ad-free experience. The subscription plans also include exclusive collections that feature shows and shorts that can’t be found elsewhere. Asiancrush is another option for those who want to watch K-drama and other Asian content without the use of a VPN.

It’s similar to KT U+ TV Mobile (olretv mobail), but it features a more extensive catalogue of Korean content. The app also supports N-Screen, which allows users to connect and view video across multiple devices and screens. 콕tv


Watch your favorite Asian dramas and movies anytime, anywhere with Rakuten Viki. Stream hit programming directly from Korea with multi-language subtitles. Viki is a free app that allows you to watch Korean, Chinese, and Taiwanese TV shows and films. You can also watch Asian films and television shows from Thailand, Japan, and Hong Kong.

You can use a subtitle downloader to get the captions for any video online. These apps are easy to install and use. Some of these applications can take some time depending on the length of the video and your device’s connection speed.

Captions are a great tool for people who have trouble hearing, are hard-of-hearing, or have limited mobility. They provide a full description of the dialogue and create full context for the viewer. They are available for all streaming services, pay TV providers, and devices. Closed captions and subtitles for the deaf and hard of hearing (SDH) are different from one another. While SDH assumes the end user cannot hear dialogue, closed captions do not.

Linux Kernel Device Identifier and /dev File System

The Device Identifier in the Linux Kernel

The kernel uses a number to identify devices on the system. The major number identifies which driver is responsible, and the minor number allows a single driver to drive multiple devices.

/dev/pda references the master IDE disk on the primary controller, while /dev/hdb refers to the slave drive. The partitions on these drives are found by adding the partition number to the minor node for that device.

Major Number

The major number is the identifier that tells the kernel what driver to call for a character device special file (/dev). In DDI and pre-DDI 8 drivers, it also separates block from character devices. The major number is not passed to the open routine of the device driver, but it does identify the type of device and the driver associated with that device.

Traditionally, the major number has been used to identify the driver for a device. For example, the /dev/null and /dev/zero devices are managed by driver 1, while the virtual consoles and serial terminals are handled by driver 4. The kernel uses this information at open time to dispatch to the appropriate function for that device.

Since modern Linux kernels are organized on a one-major-one-driver principle, the major number is important. It’s usually best to pass a pointer to the global structure of the device driver to the register_chrdev() routine, not to one local to the module’s initialization function.

Minor Number

The minor number is used by a device driver to distinguish among devices it controls. It is important for programs to be able to tell which drivers manage specific devices (e.g. /dev/zero or /dev/null are both managed by driver 1, and virtual consoles are handled by driver 4).

The kernel uses the dev_t data type (defined in linux/types.h>) to store both the major and minor numbers; 12 upper bits are reserved for the major number and 20 lower bits for the minor number. As a result, only the driver associated with the minor number knows about it; other parts of the kernel don’t use the minor number.

Register_chrdev uses a pointer to this structure to store the major and minor numbers, which it passes to applications when they ask for a character device file. This is important because a program that invokes register_chrdev without knowing the device major and minor number will get a different file name when it tries to open the device.


The /dev/random device is used to supply truly random data. It does so by drawing from the kernel’s entropy pool. This means that if the pool is depleted, reading from it will block until more entropy is available. This prevents attackers from predicting the next output of the device.

The blocking read of /dev/random is a necessary security feature. If an attacker could determine that a certain amount of data was generated at a particular time, they would be able to guess the outcome of cryptographic operations such as key generation.

On modern Linux systems, the /dev/random device no longer blocks unless the system believes it has insufficient entropy to generate random numbers. This is a result of a new syscall, introduced by OpenBSD and known as getentropy(2). The syscall is designed to estimate how much entropy the kernel has, rather than wait for it to deplete. It has replaced the old /dev/random file on Linux systems.


The /dev/urandom device is used to collect entropy from sources that are registered with the kernel-level cryptographic framework, and implement random number generation routines. An administrator can use the cryptoadm(8) utility to configure which providers are used with /dev/random. The /dev/urandom device will block reads if the available entropy is too low.

When “true” random data enters the system, it is counted and a precise counter is updated. This entropy is then passed to an internal random number generator (RNG) and then merged with the existing pool. The /dev/random device reads from the /dev/urandom pool and blocks reads when the entropy counter falls too low.

If the entropy from the /dev/urandom output is not reseeded often enough, an attacker may be able to guess at the next output in a predictable manner. With current technology, however, this attack would require exhausting the entire entropy pool and is therefore astronomically improbably. To combat this issue, it is recommended that the OS save a copy of the /dev/urandom entropy pool at power off.
