The more I work with performance, the less I like generated queries (incl. ORM-driven generators).

Like this other team came to me complaining that some query takes >3minutes to execute (an OLTP qry) and the HTTP timeout is 60 seconds, so.... there's a problem.

Sure, a simple explain analyze suggests that some UIDPK index is queried repeatedly for ~1M times (the qry plan was generated for 300k expected invocations), each Index Scan lasts for 0.15ms. So there you go.. Ofc I'd really like to see more decimal zeroes, rather than just 0.15, but still..

Rewriting the query with a CTE cut down the execution time to pathetic 0.04sec (40ms) w/o any loops in the plan.

I suggest that change to the team and I am responded a big fat NO - they cannot make any query changes since they don't have any control on their queries

....
*sigh*
....
*sigh*
but down to 0.04sec from 3+ minutes....
*sigh*

alright, let's try to VACUUM ANALYZE, although I doubt this will be of any help. IDK what I'll do if that doesn't change the execution plan :/ Prolly suggest finding a DBA (which they won't, as the client has no € for a DBA).

All this because developers, the very people sho should have COMPLETE control over the product's code, have no control over the SQLs.

This sucks!

!rant

Ever find something that's just faster than something else, but when you try to break it down and analyze it, you can't find out why?

PyPy.
I decided I'd test it with a typical discord bot-style workload (decoding a JSON theoretically from an API, checking if it contains stuff, format and then returning it). It was... 1.73x the speed of python.

(Though, granted, this code is more network dependent than anything else.)

Mean +- std dev: [kitsu-python] 62.4 us +- 2.7 us -> [kitsu-pypy] 36.1 us +- 9.2 us: 1.73x faster (-42%)

Me: Whoa, how?!
So, I proceed to write microbenches for every step. Except the JSON decoding, (1.7x faster was at least twice as slow (in one case, one hundred times slower) when tested individually.
The combination of them was faster. Huh.

By this point, I was all "sign me up!", but... asyncpg (the only sane PostgreSQL driver for python IMO, using prepared statements by default and such) has some of it's functionality written in C, for performance reasons. Not Cython, actual C that links to CPython. That means no PyPy support.

Okay then.

Which is the best book or resource to study analysis of algorithms ??need help guys 🙄

The dev tools of browsers

I was reviewing an Angular (remember this) project where I work to find any possibilities to optimize the performance of app. For a moment an idea came to me to look and analyze package.json and see if there is any package listed there but it's not being used in the application.

...aaaandd there were fucking 32 unused packages. 32 packages that have been installed but are not used anywhere in the application. 32!!!!!

And you know what the best part is. 2 of them were react packages. I mean, literally, their name was react-bllabllablla- component, and when I visited npmjs website, their description was react component that does bllabllablla. It's fucking react....... It's in the name, it's in the description. Is my company giving jobs to fucking blind developers or what? I'm going crazy!

Screen Usage Tracking at Work: Balancing Productivity and Privacy

Introduction
In today’s fast-paced, tech-driven work environments, screen usage tracking has become an essential tool for organizations aiming to improve productivity, security and efficiency. Modern organizations use these monitoring tools to track employee digital device activities because they need to ensure productive time usage. Screen usage tracking generates important privacy issues and ethical problems regarding technological implementation. The successful implementation of productive spaces must preserve worker privacy rights. The following article addresses all aspects of workplace screen usage tracking, including its advantages and disadvantages and proper implementation guidelines.

The Need for Screen Usage Tracking in the Workplace
The demand for screen usage tracking arises from several factors. Digital activity monitoring enables employers to confirm that staff members concentrate on their work tasks while they are at their desks. Remote work and hybrid models have become standard in workplaces because employees can no longer prove their productivity through office attendance. Employers need to monitor how workers spend their time at work because they want both performance outcomes and adequate time management.
Businesses operating in specific industries need to track their employees' activities to secure data because regulatory standards demand it. Through online activity tracking, employers achieve two objectives: they detect suspicious behavior right away and stop employees from accessing unauthorized confidential data. Screen usage tracking functions as an essential tool for both business efficiency maintenance and security protection of organizational assets.

Benefits of Screen Usage Tracking
Reduces Distractions
Employees lose their focus on work when there is no oversight system in place. Screen tracking ensures that employees are focused and using their time effectively, especially during work hours. Work hour restrictions on particular apps and websites through blocking mechanisms help employees stay focused on their tasks.
Enhances Security and Compliance
Employees lose their focus on work when there is no oversight system in place. Work hours require employees to remain focused while using their time effectively because screen tracking provides this oversight. Work hour restrictions on particular apps and websites through blocking mechanisms help employees stay focused on their tasks.
Data-Driven Insights
Screen usage data generates important information about employee work habits as well as employee engagement levels. By monitoring screen usage data managers can identify workers who require extra support and training along with identifying staff members who work excessively and those who perform above expectations. Staff management strategies and workplace performance benefit from these insights gained.

Future of Screen Usage Tracking in Workplaces
Screen usage monitoring will experience future evolution through technological developments that define how tracking occurs. These screen usage tracking tools will benefit from Artificial Intelligence (AI) because it brings both enhanced accuracy and usefulness. Artificial intelligence programming systems analyze staff behavioral patterns to generate forecast data which leads to predictive productivity improvement strategies.
Privacy laws together with regulations, will likely advance in their development. Organizations must discover methods to integrate employee rights protection systems with their monitoring strategies due to rising data privacy concerns. Organizations will adopt standard tracking policies based on transparency and employee consent to maintain ethical and legal handling of employee data.
Qoli.AI drives revolutionary changes in screen usage tracking through its leading AI technology solutions. Data-driven business decisions through Qoli.AI become possible because they provide up-to-the-minute employee performance and behavioral data while adhering to privacy limits. The platform integrates advanced technology to connect with workplace systems which provides employees with trustworthy monitoring solutions.

Conclusion
The implementation of work screen monitoring serves both positive and negative functions. Employment screen tracking enables productivity enhancement and security alongside operational efficiency at the cost of severe privacy issues and moral problems. The successful implementation of work performance enhancement requires organizations to maintain the proper balance between performance upliftment and employee privacy protection. The use of screen tracking tools benefits employers when they maintain transparency and gain employee consent, as well as develop ethical standards that protect employee trust and workplace morale.

Lighthouse Bookkeeping LLC: Expert Bookkeeping Services for Service Businesses with Comprehensive Financial and Monthly Reports

Running a service business requires careful attention to detail, especially when it comes to managing your finances. At Lighthouse Bookkeeping LLC, we specialize in offering tailored bookkeeping for service businesses, ensuring that your financial records are organized, accurate, and up to date. Our expert team provides a wide range of services, from generating detailed bookkeeping financial reports to delivering bookkeeping monthly reports that help you make informed business decisions.

Located in Brentwood, TN, Lighthouse Bookkeeping LLC is dedicated to helping service-based businesses stay on top of their financial obligations and avoid costly mistakes. Whether you're a consultant, contractor, healthcare provider, or any other type of service business, we are here to manage your financials and provide the reports you need to track your success.

Why Bookkeeping is Essential for Service Businesses
Service businesses face unique challenges when it comes to financial management. Unlike product-based businesses, service-based companies may deal with fluctuating revenues, project-based billing, and different client payment schedules. Keeping track of income and expenses accurately is vital to ensure profitability, tax compliance, and financial growth.

Bookkeeping for service businesses is essential for the following reasons:

Accurate Financial Tracking
Service businesses often operate on contracts or agreements with varying payment schedules. Proper bookkeeping ensures that all client invoices, payments, and expenses are accurately recorded, giving you a true picture of your business’s financial health.

Expense Management
Service businesses may incur expenses related to travel, supplies, marketing, and more. By tracking these expenses properly, we help ensure that your books remain organized and you can easily identify opportunities to cut costs or increase profits.

Tax Compliance
Bookkeeping is essential to staying compliant with tax regulations. We ensure that your financial records are accurate and complete so that you can file your taxes without any issues. This helps you avoid penalties and take advantage of all potential tax deductions.

Cash Flow Management
For service businesses, cash flow can fluctuate depending on the nature of contracts and billing cycles. We help you keep track of incoming payments and outgoing expenses, ensuring that you have enough working capital to operate smoothly.

How We Provide Comprehensive Bookkeeping Financial Reports
At Lighthouse Bookkeeping LLC, we understand that financial reports are the backbone of decision-making. Our bookkeeping financial reports provide a detailed view of your business’s financial performance, allowing you to assess profitability, track your financial goals, and make strategic business decisions.

Our bookkeeping financial reports include:

Profit and Loss (P&L) Statements
The P&L statement shows your business’s income and expenses over a specific period. It helps you understand your revenue, cost of goods sold, and operating expenses, giving you insights into whether your business is profitable.

Balance Sheet
The balance sheet provides a snapshot of your business’s financial position at a given point in time, listing your assets, liabilities, and equity. It helps you assess your business’s financial stability and ability to cover its debts.

Cash Flow Statement
The cash flow statement tracks the flow of cash in and out of your business. This report provides essential information for managing cash flow, helping you ensure that you have sufficient cash to cover day-to-day expenses.

Accounts Receivable and Accounts Payable Reports
These reports track outstanding payments from clients (accounts receivable) and amounts you owe to vendors (accounts payable). They are essential for maintaining healthy cash flow and ensuring you are on top of any outstanding financial obligations.

Job or Project-Based Reports
For service businesses that work on projects or contracts, we provide detailed reports that break down income and expenses related to specific jobs, helping you assess the profitability of individual projects or clients.

The Importance of Bookkeeping Monthly Reports
In addition to providing periodic financial statements, bookkeeping monthly reports offer a snapshot of your business’s financial status on a month-to-month basis. These reports allow business owners to track performance, analyze trends, and make timely adjustments to their strategies.

Here’s why bookkeeping monthly reports are critical for service businesses:
