Counterpoint: I just spent 6 hours trying to figure out why my code wasn't running, and it turns out it's because I forgot to start my service class with @service

Also I did not think it was possible for something to be more wretched than RegEx but then I was introduced to cron expressions! What do you mean 0 0 8 * * * means "every day at 8 am??? I'm going to kill you.

Week 8 as a Java dev and i think SpringBoot notations should be outlawed

[matrim-cauthons-hat]

having had a couple of days to think on things after finishing SM2's main campaign, im just gonna jot down my thoughts here. this isnt a critical review or any such, just my own musings and feelings that i had while playing the game, not some expression of universal experience

honestly, it was kinda mid. like, thats fine. its acceptable for a game to just be OK. a solid 6/10. thats above average. a passing grade. i kno what video game people are like (yes im looking at your people who think 7/10 is the lowest possible score a truly average game should get) there were just a couple of things that really brought it down for me. oh yeah this will contain spoilers, obvs

the chaos forces. didnt enjoy fighting them. nowhere near as fun as fighting the nids was. there was just something about fight the endless hordes of hunger, watching the hormagaunts pile up against the walls and climb over each other, thinning the herd as much as you can but knowing that you'll run out of grenades and bolts before they run out of bodies. or going toe to toe with hive knights and watching all the gaunts heads explode when you slay the synapse creature. great stuff! t-sons are just full of dust :(

the final boss fight... was a bit shit. okay that might be harsh, it was alright. until the end. every other boss fight until then i got to preform an exaction on the guy. it was very satisfying, watching titus rip bits off of a foe to finish them off. following behind calgar and then watching a cutscene where the titus grabs a Thing and then the sorceror goes :0 before turning to dust? lame. titus should have climbed on his warp-surfboard and ripped his arm off or something. especially satisfying since soceror got away the first time you fight him.

speaking of fighting, what the hell is up with the game just resetting your loadout to a auto bolt rifle, regular bolt pistol, and chainsword every so often? like by mid game ive already figured out what kit i have the most fun playing with, and the game has been out for like two and a half months, this should have been patched by now.

i want more pistols too. like i know the space marines also have the inferno pistol, flamer pistol, and neovolkite pistol. you could say that the neovolkite is incredibly rare and only bladeguards and some officers get them, which okay, fair enough. but the other two? tactical squad sergeants can get them like come on! and a powerfist. that would be sick

why. no. necrons. i got really excited when i saw the necron glyphs. i was like "titus is right, those look like the glyphs ive seen many times in Warhammer 40,000: Mechanicus". i thought we were do for a second mix up! because i was getting bored of fighting choas. but no it was just the blackstone pillars. yeah they're important to the overarching plot yadda yadda yadda but i wanna hack up some crons with a sword

finally, that final stand after picking up the standard. id seen it hyped up online. i was excited. i was going to stand there with my squad and hold out against possibly endless waves of tzangors until we nearly break, only to realise the enemy has stopped and we have won! or to even be overrun and forced to pull back! exciting! and then calgar just shows up and kills them all in a cutscene :(

A guide to setting up automated data workflows with Snowflake.

Introduction

In today’s data-driven world, organizations need to process vast amounts of data efficiently. Snowflake, a cloud-based data platform, offers powerful automation features that help streamline workflows, reduce manual effort, and enhance data processing efficiency.

Automating data workflows in Snowflake is essential for:

Real-time data ingestion from various sources.

Incremental data processing using change data capture (CDC).

Scheduled data transformations for ETL/ELT pipelines.

Trigger-based workflows that respond to new data events.

This guide will walk you through Snowflake’s automation features, step-by-step implementation, and best practices to ensure optimal workflow execution.

Understanding Snowflake Automation Features

Snowflake provides several built-in automation tools to simplify data workflows:

1. Snowpipe: Automated Data Ingestion

What it does: Snowpipe enables continuous and automated loading of data from cloud storage (AWS S3, Azure Blob, or Google Cloud Storage) into Snowflake tables.

Key Benefits:

Near real-time data ingestion.

Cost-efficient pay-per-use pricing model.

Automatic triggering using cloud storage event notifications.

2. Streams: Change Data Capture (CDC) in Snowflake

What it does: Streams track inserts, updates, and deletes in a table, enabling incremental data processing.

Key Benefits:

Efficient CDC mechanism for ETL workflows.

Ensures only modified data is processed, reducing compute costs.

Works seamlessly with Snowflake Tasks for automation.

3. Tasks: Automating SQL Workflows

What it does: Snowflake Tasks allow scheduling and chaining of SQL queries, enabling sequential execution.

Key Benefits:

Automates transformations and incremental data loads.

Supports event-driven workflows.

Can be scheduled using cron expressions.

4. Stored Procedures: Automating Complex Business Logic

What it does: Stored procedures allow procedural execution of SQL and Python-based logic within Snowflake.

Key Benefits:

Enables advanced data processing beyond standard SQL queries.

Supports loops, conditions, and API calls.

Works well with Tasks and Streams for automation.

Step-by-Step Guide to Setting Up Automated Workflows in Snowflake

1. Automating Data Ingestion with Snowpipe

Step 1: Create an External Stage

sqlCREATE OR REPLACE STAGE my_s3_stage URL = 's3://my-bucket/data/' STORAGE_INTEGRATION = my_s3_integration;

Step 2: Define a File Format

sqlCREATE OR REPLACE FILE FORMAT my_csv_format TYPE = 'CSV' FIELD_OPTIONALLY_ENCLOSED_BY = '"';

Step 3: Create a Table for the Incoming Data

sqlCREATE OR REPLACE TABLE raw_data ( id INT, name STRING, created_at TIMESTAMP );

Step 4: Create and Configure Snowpipe

sqlCREATE OR REPLACE PIPE my_snowpipe AUTO_INGEST = TRUE AS COPY INTO raw_data FROM @my_s3_stage FILE_FORMAT = (FORMAT_NAME = my_csv_format);

✅ Outcome: This Snowpipe will automatically load new files from S3 into the raw_data table whenever a new file arrives.

2. Scheduling Workflows Using Snowflake Tasks

Step 1: Create a Task for Data Transformation

sqlCREATE OR REPLACE TASK transform_data_task WAREHOUSE = my_warehouse SCHEDULE = 'USING CRON 0 * * * * UTC' AS INSERT INTO transformed_data SELECT id, name, created_at, CURRENT_TIMESTAMP AS processed_at FROM raw_data;

✅ Outcome: This task runs hourly, transforming raw data into a structured format.

3. Tracking Data Changes with Streams for Incremental ETL

Step 1: Create a Stream on the Source Table

sqlCREATE OR REPLACE STREAM raw_data_stream ON TABLE raw_data;

Step 2: Create a Task to Process Changes

sqlCREATE OR REPLACE TASK incremental_etl_task WAREHOUSE = my_warehouse AFTER transform_data_task AS INSERT INTO processed_data SELECT * FROM raw_data_stream WHERE METADATA$ACTION = 'INSERT';

✅ Outcome:

The Stream captures new rows in raw_data.

The Task processes only the changes, reducing workload and costs.

4. Using Stored Procedures for Automation

Step 1: Create a Python-Based Stored Procedure

sqlCREATE OR REPLACE PROCEDURE cleanup_old_data() RETURNS STRING LANGUAGE PYTHON RUNTIME_VERSION = '3.8' HANDLER = 'cleanup' AS $$ def cleanup(session): session.sql("DELETE FROM processed_data WHERE processed_at < CURRENT_DATE - INTERVAL '30' DAY").collect() return "Cleanup Completed" $$;

Step 2: Automate the Procedure Execution Using a Task

sqlCREATE OR REPLACE TASK cleanup_task WAREHOUSE = my_warehouse SCHEDULE = 'USING CRON 0 0 * * * UTC' AS CALL cleanup_old_data();

✅ Outcome: The procedure automatically deletes old records every day.

Best Practices for Snowflake Automation

1. Optimize Task Scheduling

Avoid overlapping schedules to prevent unnecessary workload spikes.

Use AFTER dependencies instead of cron when chaining tasks.

2. Monitor and Troubleshoot Workflows

Use SHOW TASKS and SHOW PIPES to track execution status.

Check TASK_HISTORY and PIPE_USAGE_HISTORY for errors.

sqlSELECT * FROM SNOWFLAKE.INFORMATION_SCHEMA.TASK_HISTORY WHERE STATE != 'SUCCEEDED' ORDER BY COMPLETED_TIME DESC;

3. Cost Management

Choose the right warehouse size for executing tasks.

Pause tasks when not needed to save credits.

Monitor compute costs using WAREHOUSE_METERING_HISTORY.

4. Security Considerations

Grant least privilege access for tasks and Snowpipe.

Use service accounts instead of personal credentials for automation.

Encrypt sensitive data before ingestion.

Conclusion

Snowflake provides powerful automation tools to streamline data workflows, enabling efficient ETL, real-time ingestion, and scheduled transformations. By leveraging Tasks, Streams, Snowpipe, and Stored Procedures, you can build a fully automated data pipeline that is cost-effective, scalable, and easy to manage.

Laravel vs. The Competition: What Sets it Apart in Web Development

Laravel has gained popularity as one of the most favourable PHP frameworks, admired by developers for its elegance, ease of use, and powerful features. Developed by Taylor Otwell, it is a free and open-source PHP web application framework that adopts the Model-View-Controller (MVC) architectural pattern.

As per the recent data, there are approximately 757,533 live websites which are using Laravel. This blog discusses what differentiates Laravel from other frameworks and why it has become the preferred choice for many companies and developers.

Laravel: A Brief Overview

Laravel is built on several Symfony components which serve as a well-tested, stable base of code. This base enables Laravel to offer advanced features while preserving high performance. The framework aims to ease the development process by handling common tasks typically involved in web projects, such as authentication, routing, sessions and caching.

As more businesses recognize the value of Laravel, the demand for Laravel development services has grown exponentially. These services can greatly improve your web development projects by using the framework capabilities, best practices, and industry experience.

Key Features that Set Laravel Apart

Eloquent ORM (Object-Relational Mapping)

Eloquent ORM is the built-in ORM of Laravel and is considered one of the most advanced ORM implementations in PHP. It enables developers to work with database objects and their relationships using simple, easy-to-understand language. This simplifies the code as well as eliminates the requirement for manual SQL queries, with the guarantee that data access is secure and efficient.

Artisan Console

Artisan is a command-line interface of Laravel built into the framework itself. It offers a wide range of useful commands for building a Laravel app.

Artisan provides the ability to automate those tedious, repetitive tasks which are normally manual and non-productive. It is also able to generate template code for new controllers, models and migrations, which can then be modified to fit specific needs, hence accelerating the entire process of development.

Template Engine (Blade)

Laravel’s Blade templating engine is incredibly flexible and powerful, yet it allows developers to use plain PHP code in the templates. Unlike many PHP templating engines, Blade does not restrict you from using code in views, making it possible to implement complex data operations right within the template, while still keeping the syntax clean and readable.

Security

Laravel provides a robust security framework that is fundamental to the development of web applications. It has built-in protections against common threats such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). Laravel uses hashed passwords, meaning the actual password is never stored in the database, just a secure hash of it.

Libraries & Modular

Laravel comes with pre-built libraries and modules that make it easier to enhance an application's capabilities without building features from scratch. One of the standout libraries is the Authentication library, which is easy to implement and can be customized to meet specific needs, providing a ready-to-use way to integrate secure authentication methods into applications.

Automated Task Scheduling

Laravel's command scheduler allows the programmatic scheduling of periodically executed tasks. Traditionally, developers have had to generate a Cron entry for each task they need to be scheduled. Laravel simplifies this with a fluent, expressive interface to define command schedules within Laravel itself, making it easier to manage tasks directly through the framework.

Laravel vs. The Competition

Performance Optimization

Laravel often outperforms its competitors due to built-in caching mechanisms and optimization tools, such as route caching, configuration caching, and view compilation. Unlike some frameworks like Zend, which may require manual optimization techniques, Laravel provides straightforward commands to boost performance, making it inherently faster and more efficient for complex applications.

Built-in Tools

Laravel comes with several pre-packaged tools such as Eloquent ORM, migration system, and seeding that are not as robust or even available in some other PHP frameworks like CodeIgniter. This suite of tools can significantly reduce development time and increase productivity by eliminating the need to write boilerplate code.

Community Support and Ecosystem

Laravel boasts a large, active community and a rich ecosystem, which includes comprehensive forums, extensive tutorials, video resources, and third-party packages. This is a contrast to smaller communities like that of Phalcon, where fewer resources and community support can limit problem-solving and learning opportunities.

Scalability

Laravel's ability to scale is comparable to that of any leading framework. It manages resources efficiently and can handle large-scale applications with ease. This stands in contrast to some PHP frameworks that might struggle under the weight of enterprise-level user loads or complex back-end operations.

Conclusion

Laravel continues to lead in the PHP framework domain due to its ease of use, comprehensive feature set, and robust community support. Whether it's the intuitive syntax or security features, Laravel provides a foundation that facilitates both simple and complex web application development.

Leveraging the expertise of a reliable Laravel development company like Shiv Technolabs, you can maximize the potential of Laravel to achieve your web development goals effectively and efficiently.

Noida's Shree Krishna Graphics acquires Cron CtP

Noida-based Shree Krishna Graphics, a pre-press bureau and a supplier of offset plates, recently acquired a CRON UVP-4664G+I+ commercial & newspaper CtCP system from Monotech Systems. It already had a thermal CtP system from Technova from the date of its establishment in August 2022.

Anupam Gupta, director of Shree Krishna Graphics, also runs two other companies — Krishna Sales, which deals in plates and consumables from prominent brands such as Technova, DIC, and Toya as well as Crystal Graphics, an offset plate provider in Ghaziabad.

“The surge in demand for plates was a catalyst for us to start Crystal Graphics with the Amsky thermal CtP system. Later on, it became difficult to fulfill the demand for plates from printers in Noida. This need was the catalyst for Shree Krishna Graphics.” Just like Shree Krishna Graphics, Crystal Graphics is also equipped with two systems for plate production.

Gupta said the installation of the CRON CtP was the result of positive feedback that was doing the rounds about the machine in the market from its customers. He praised the ease of maintenance, accuracy, and speed of the press as well as the technical support of Monotech Systems. The CRON UVP-4664G can produce 28 plates per hour (28*40 inch), supporting plate sizes up to 1160mm. Dot imaging, accurate dot reproduction with a minimum error rate, and a 64-channel capacity are some of its key features.

Loksatya, Jagat Kranti, and Hindustan Times along with several other newspapers, publishers, and packaging and commercial printers form the clientele base of Shree Krishna Graphics.

Expressing his thoughts on digital printing, he said its growth is not along expected lines in India right now. “drupa 2016 predicted digital printing to be a game-changer in the industry. It has been eight years but the expected rate of growth hasn't seen its peak.” Though he acknowledges that the value of additional printing is something that only can be done digitally, he says the quality of output and cost-effectiveness of printing in offset are unmatchable. “Every offset printer has a digital printing system but is not ready to give up offset completely.”

Gupta recalls his transition to entrepreneurship, leaving behind salaried jobs across different sectors. “A printing technologist by profession, I served as a production head at The Indian Express, later joining the Ministry of social justice as a gazetted officer. However, my industry-centric mindset led me to The Times of India (Sahibabad) and eventually as the north India head of CMS Info Systems (Mumbai). This journey paralleled the establishment of Krishna Sales in 2010 until 2013 when I devoted myself entirely to business.”
