Stealing/boosting id from consistantly-changing

[Image descriptions in order: two screenshots of a Reddit post by u/iambeaker titled "'Twas the night before my resignation…" The post reads "I was brainwashed at an early age that loyalty and hard work would add countless "0's" to your paycheck. I remained optimistic after receiving year after year of 3% raises and working holidays. I missed my children's first steps, their school functions, and other life events so I could make the CEO more money.

After the passing of my stepfather and my boss calling me during the funeral, asking me to troubleshoot an issue while my mom cried into my shoulder, enough was enough. I changed companies and made a personal pledge to put family first and my career a distant third or fourth.

Fast forward to present day…. I find myself as the cornerstone of our department. Many of our clients' processes are automated through custom API developed by me. I have maintained a thorough documentation library on how to support the API, the reports, and all of its dependencies. I have offered to train backup so we are not single threaded. My manager told me "No way, we would never do anything to lose you!" Up to now, life was good.

At the beginning of December, ABC Company was audited by the government and found to be out of compliance. They hired my company to regain their compliance by the end of the year or risk fines near $750,000. ABC Company dragged their feet getting us the information we needed to start on the work.

I save my vacation days so I can take the week between Christmas and New Years off. I spend it with my kids to make up for all the time I lost when I worked when they were younger. This time is very precious to me.]

["Last week and this week, I have been notifying the project manager and my manager about my time off. I let them know I would need ABC Company's information soon so I can start on it. I offered to work extra hours to ensure my piece would be finished prior to Christmas Eve.

On Tuesday, my manager calls me and tells me ABC Company finally sent the data over I requested over two weeks ago. He looked beaten because he knew what was about to happen. I told him who should I walk through the project with because I'm off after Christmas. My manager says, "I'm sorry. But I have to ask you to work. I declined your time next week."

I asked, "What happens to my vacation time?" My boss says, "I'm sorry. You know the rules. Use it or lose it. I fought for you but HR wouldn't budge."

I drafted my resignation letter after the call, set it to delay delivery on Monday at 8am, and closed up shop.

ABC Company will pay $700,00 because nobody knows how to program that system since there is no back up. Our other clients will be expecting their monthly, quarterly, and annual reports within the first week of January. No one knows how to do this. We had six projects in progress involving extensive API and reporting, now those projects are dead in the water. Seven clients prepaid for API and automation upgrades in 2022 Q1. I don't know what will happen to those.

Please remember. Family first. You never get that time back."]

[Several screenshots of a text conversation between OP and their boss. It goes:

Boss: Hope you have a great Christmas

Boss: [OP] please call me as soon as you can.

Boss: I received your email. I understand that you are upset but resigning is not the best choice in this circumstance.

Boss: [OP], I have been your friend for five years. I'm asking you as a friend, not a manager to reconsider and call me. Let's talk about this

Boss: Hey, you made your point. You can have today off if you call me and let me know when we can expect you tomorrow. But you need to call me.

Boss: This is ridiculous. Do you know what your actions are going to do to the company? To me? You made your point. Just call me and we will figure out your vacation. But we need]

[Boss: This is ridiculous. Do you know what your actions are going to do to the company? To me? You made your point. Just call me and we will figure out your vacation. But we need [task] done by Friday.

Boss: Why won't you answer your phone? Your wife won't answer hers either. HR needs to talk to you.

Boss: I got out of a meeting with [name]. If we don't get this done for [client] we get penalized and that $ comes from bonus and pay increases. I want you to know that. If you don't finish that, nobody gets a bonus or a pay increase this year. This will be common knowledge

Boss: [OP], I've been talking to [name] We assume you resigned because you were going to lose your vacation. Here's the deal… if you call me by 3, we will rollover your vacation to 2022, but we still need you to work T-F. We need [task] done before 12/31. Call me before 3]

[Boss: [name] sent over a Corrupt CSV file and [name] followed your documentation to manually process it. [Name] tried python and the states can't see their dailies. You gotta help us here Call me!!!

Boss: Dude, log back in and help fix this stuff. Name your price. The states can't see their reports. [Company's] going to fine us [name] wants to know if the reports will be complete by 1/6. Family is important, but we are talking about peoples jobs on the line.

OP: Hey, I will be happy to return to [company] for $80/hour, $5000 immediate sign on bonus, and 6 weeks PTO. With a 12 month guarantee. Send that to me in writing and I'll start immediately.

Boss: Cmon. This is ridiculous. I don't even get paid that much. Why do you think you deserve this much? Quit being so full of yourself, be a team player, login and save this company.

Boss: Pick up your phone. I need to know what reports are due next week. We don't want to be fined.]

[Boss: Not even a counteroffer? Every hour the dailies are down, that's $1000 per STATE. [Name] does not know how to fix it. I don't know how much clearer I need to be. Log back in, fix his mistake, get [task] done, be a team player. We are family too you know.

OP: Please stop calling my dad. He has nothing to do with this. You can call me all you want but don't call my emergency contacts. I resigned, I didn't die.

Boss: We had to make sure you were ok.

Boss: Congrats [OP]. You cost the firm $19k. You taught us a lesson. Now pick up the phone and we talk about a reasonable offer. But you need to fix this states daily thing right now. That is your priority

Boss: Pick up the phone HR wants to conduct their exit interview]

[Boss: [OP], here are your priorities

Fix state dailies

Complete [task]

Provide [name] list of 1/6 reports

Train [name] being your back up

Boss: How much time will it take to fix the dailies? I need to tell [name]

OP: What does this mean? To be 100% clear, I resigned today. I don't have priorities or projects. I am no longer an employee. If you would like me to return, I gave you my offer

Boss: There was a time when a two week notice would before you resigned. Maybe you should be a better businessman and give us two weeks? [OP], we all make sacrifices. You have to sacrifice one week of vacation so we can fix some stuff around this department. Next year, maybe you won't ask off for this week until closer to December and you know what the workload is. You gambled and you lose. Just laugh it off and log on, let's get these states fixed. Let's fix [company]. Let's get this department fixed

Boss: Pick up your phone. It is [name] and me We need to know what it's going to take to fix the state dailies. $19k/hour is going to murder us

Boss: [OP] answer your phone

Boss: ANSWER YOUR PHONE!!!

OP: For $10,000, I'll fix your state daily file and train the team on how to run it so this doesn't happen again. Nobody is familiar with Python or understands Alteryx or SSIS. I can train them all using my existing documentation. The answers are all there.

OP: I can fix the state daily file tonight to avoid further fines and train the team the rest of the week. But I will NOT do any work on [project] or provide any information about recurring reports.

Boss: Is that some kind of joke? Your documentation does not have the answer. We've been through it [censored] laughing at $10k. You already cost us $32k today, you want to squeeze another $10k. You got greedy over Christmas]

[Boss: $10k

Fix daily files

Train the team

Do the [project]

Run the recurring reports for January

Deal?

Then we are done.

OP: That is a generous offer. But I'm firm on my offers. But I'm telling you, you don't need me. The answer is in the documentation.

Boss: Then where is it? If you were a true person of your word, you would tell us and save this company. Save your coworkers. Save their paychecks and their bonuses.]

[A gif of Homer Simpson driving. He turns behind him to shout angrily, then the camera changes to a wide shot where he drives over a short wooden bridge, throwing a lighter onto it and lighting it on fire.]

[An update from the OP, which says, "Present Day:

Throughout the day, the manager and CEO send a barrage of texts and phone calls.

One of my coworkers finds the documentation and fixes the reports. Later in the afternoon, he is served corrective action because he was accountable for processing the corrupted file and did not find the documentation faster. He tells me the manager, HR, and the CEO spent all night finding evidence to support the corrective action. I tell him to get his resume up to date. Total down time: 16 hours

Around 3pm, I get a phone call from a new number. It was the client's business manager (the liaison between the former company and the client). I explained to her the delay of getting data until Christmas (despite multiple requests), the loss of a full week of PTO, the text messages/phone calls, and my offer to come back to help her company reach compliance.]

["The business manager told me a different story. The manager and CEO called her earlier to inform her I quit and I am "stalling the project as ransom" in order to obtain more money. I explained how one could skew this view, but I am not actively seeking to return. After observing how the company treats their employees and after being treated post resignation, I have no interest in returning to the company.]

["The business manager asks me what terms (rate, signing bonus, etc.) what I was seeking to return to my former company. She tells me she will call back in an hour and not respond to any more texts from the manager or CEO.

CEO Text: Did the business manager call you? Did she give you a piece of her mind?

Manager Text: I bet the business manager is going to make you personally pay for that fine!

The business manager calls me back on a conference call and asks, "What do you need to finish this project? Software, data, tools, etc.?" I give her a list of everything I need. I answer other questions related to the project.

She says, "Here's the plan. We are going to offer you a contract to finish this API for us by the end of the year for double the hourly rate you asked. If you can finish by 12/31, we will give you the signing bonus. After the New Year, we will see where we are staffing wise and maybe, we can find you a spot, but there is no guarantee, especially if you do not the project. Is that a deal?"]

["I agree to the terms. I inform to put terms in writing and I can start as soon as IT gives me a virtual machine. The business manager says, "No problem, legal checked the contract and there is a clause stating if your former company is unable to perform a function which they agreed to do, we are able to outsource it to a third party and charge the company for it. I just need them to state they are unable to perform the API function, and we will bill them for your time."

TLDR; The client is giving me a contract and billing my former company double my asking rate because the former company is unable to successfully execute a function by the deadline they agreed to in a contract."]

Best Valves for Water Supply Systems: Domestic vs Industrial Use

Water supply systems rely on specific valves for safe, reliable flow control. The ideal valve depends on whether it’s for domestic plumbing or industrial pipelines, considering factors like pressure, flow, material, and maintenance needs.

For domestic use, ball, gate, and angle valves are ideal due to low pressure and ease of use. For industrial systems, butterfly, globe, and check valves handle high pressure and continuous operation. Choose based on flow type, pipe size, and durability requirements.

🏠 Domestic Water Supply Valves Valve Type Use Case Advantages Ball Valve Kitchen, bathroom shutoff Easy operation, quick control Gate Valve Main water inlet Good for isolation, full flow Angle Valve Tap/faucet connection Compact, easy to install Check Valve Prevents backflow in tanks/pumps Ensures water hygiene

Float Valve Water tanks Auto water level control 🏭 Industrial Water Supply Valves Valve Type Use Case Advantages Butterfly Valve Large pipelines, treatment plants Compact, low cost, fast operation Globe Valve Flow regulation Precise control, durable Check Valve (NRV) Pump lines, water plants Prevents reverse flow Pressure Reducing Valve High-rise or high-pressure lines Controls pressure safely Gate Valve (Heavy-duty) Distribution mains Full flow, robust structure

🔍 Key Differences: Domestic vs Industrial Valves Factor Domestic Use Industrial Use Pressure Rating Low (up to 10 bar) High (10+ bar, often 25+ bar) Material Brass, PVC, CPVC Cast iron, stainless steel, ductile iron Valve Type Small, user-operated Heavy-duty, automated options Operation Manual Manual or pneumatic/electric actuated Maintenance Low Scheduled and frequent

✅ How to Choose the Right Water Valve Check Water Pressure Domestic: Low-pressure valves Industrial: High-pressure-rated valves Size of Pipeline Residential: ½”–2” Industrial: 2”–48” Purpose On/off control = Ball or gate Flow regulation = Globe Prevent backflow = Check valve Material Domestic: Brass, PVC Industrial: Steel, CI, DI, bronze 🧠 Pro Tip Use certified ISI/ISO valves to ensure compliance and longevity. For industrial use, valves should meet ASME, AWWA, or API standards.

❓ FAQ: People Also Ask Q1. What is the best valve for home water supply? Ball valves are best for homes due to their easy operation, tight sealing, and long life.

Q2. Which valves are used in industrial water lines? Common choices include butterfly, gate, globe, and NRV valves due to their high durability and pressure handling.

Q3. Can I use PVC valves for industry? No, PVC valves are only for low-pressure systems. Use metal or ductile iron valves in industrial applications.

Q4. Are ball valves better than gate valves? For homes, ball valves are more convenient. In industry, gate valves provide better flow with minimal resistance.

Tether Is Now a Shadow Central Bank—And No One's Ready for It

$1 billion in quarterly profit. $120 billion in U.S. Treasury exposure. $5.6 billion in excess reserves. These aren’t the numbers of a Silicon Valley unicorn or even a traditional financial institution. These are the numbers of Tether, the world’s largest stablecoin issuer. And at this point, let’s stop pretending: Tether isn’t just a crypto company. It’s becoming a shadow central bank, and the world’s regulators, economists, and investors are only just waking up to that fact.

This isn’t about stablecoins anymore. It’s about who really controls dollar liquidity in the 21st century—and whether traditional institutions can keep up.

Tether’s Quiet Ascent to Systemic Relevance

Tether posted over $1 billion in operating profit in Q1 2025, thanks largely to returns on its nearly $120 billion exposure to U.S. Treasurys. For context, that would make Tether one of the largest holders of U.S. government debt—sitting not far behind sovereign nations like South Korea or the UK. That’s not just a fun fact. It’s a structural shift in how dollar demand—and distribution—is taking place globally.

Tether’s USDT stablecoin grew by $7 billion in supply in just three months, with 46 million new wallets added. This isn’t a marginal product anymore. It’s a global dollar rail for hundreds of millions, many of whom live in countries with unstable currencies, capital controls, or underdeveloped banking systems.

Tether has become the offshore dollar bank for the crypto-native and the financially excluded.

This Is the New Eurodollar—Only Faster, Harder, and Borderless

The Eurodollar system—U.S. dollars held outside of U.S. borders—has shaped global finance since the 1950s. But it’s opaque, slow, and built on interbank trust that occasionally collapses (see: 2008). What Tether is building is a crypto-native Eurodollar 2.0, complete with APIs, composability, and 24/7 global access.

Don’t miss the significance here. When a user in Nigeria, a DAO in Argentina, or a market maker in Dubai taps into USDT, they are accessing dollar liquidity outside the traditional system—without SWIFT, correspondent banks, or the Federal Reserve. And Tether is the clearing house.

That explains the European Union’s recent hand-wringing about dollar-backed stablecoins. Officials from the Bank of Italy warned that disruptions in these tokens—or their underlying assets—could have "repercussions for other parts of the global financial system."

They’re not wrong. If Tether sneezes, parts of the crypto economy—and increasingly, real-world remittance and commerce flows—could catch the flu.

The Paradox of Transparency and Control

Tether’s critics have long pointed fingers at its lack of transparency. But here’s the twist: Tether is now arguably more audited than many commercial banks. Its latest attestation came from BDO, a top-five global accounting firm. The company publishes quarterly reserve breakdowns, has survived multiple bear markets, and now holds more in excess reserves than some regional U.S. banks.

The latest figures show $5.6 billion in excess capital—a conservative buffer even by TradFi standards. Yes, that’s down from $7.1 billion last quarter, but let’s be real: how many other financial entities are raking in billion-dollar quarterly profits while expanding reserves and growing their user base by double digits?

And still, Tether isn’t regulated like a bank, nor does it have a lender of last resort. It’s headquartered in El Salvador, under a digital assets framework that most G7 policymakers would consider experimental at best. That’s both a feature and a bug. Tether has the freedom to act swiftly, invest in frontier tech (over $2 billion into AI, energy, and data infra), and plug into global markets that Wall Street still tiptoes around.

But if something goes wrong—if USDT depegs, if reserves become illiquid, if regulation slams the door shut in a major jurisdiction—there is no central bank to backstop this central bank-in-disguise.

Why No One in D.C. or Davos Can Afford to Ignore Tether Anymore

If you work at the IMF, the U.S. Treasury, or the ECB, this should terrify you. Because Tether isn’t just enabling crypto trading. It’s becoming a systemic piece of the global dollar infrastructure, without oversight, monetary policy alignment, or democratic accountability.

In many ways, Tether is succeeding because of its offshore structure and regulatory arbitrage. While U.S. stablecoin bills languish in legislative purgatory, and the ECB dithers on a digital euro, Tether is executing. Fast. Globally.

And unlike CBDCs, USDT doesn’t require a passport, a bank account, or a government-issued ID. It runs on-chain, around the clock. For users in Lebanon, Venezuela, or Gaza, it’s not a crypto product. It’s survival.

and Why It Misses the Point

Skeptics will say Tether is still too risky, too centralized, or too dependent on U.S. Treasurys to last. That its business model rides on artificially high interest rates, and that a Fed pivot will wipe out its profits. They’ll note the firm’s legal past, murky shareholder structure, or the fact that it isn’t licensed in most developed economies.

All of this is valid.

And yet, Tether keeps growing. Not because it’s perfect—but because the alternatives are worse. Circle’s USDC has faltered in international markets due to its bank dependencies and regulatory fragility. CBDCs are years away and often come laced with surveillance concerns. Traditional dollar accounts remain inaccessible to billions.

So users turn to what works. And right now, Tether works.

Tether Will Be the First “Crypto IMF”—Unless Governments Step Up

Here’s my bet: If no major regulatory or market event disrupts its trajectory, Tether will become the de facto international dollar lender of last resort in crypto and emerging markets within the next 2–3 years.

We’ll see sovereign wealth funds, fintech apps, and even governments quietly hold USDT as a reserve asset—not because they want to, but because it’s liquid, available, and politically neutral. We’ll see USDT rails power cross-border trade, remittances, and commodity payments in the Global South.

And if the Fed or ECB doesn’t accelerate their response—either via regulated stablecoin frameworks or meaningful CBDC deployment—they will have ceded monetary influence not to China, but to a privately-run firm headquartered in El Salvador.

Tether isn’t just winning. It’s changing the rules of the game. And if policymakers keep underestimating it, the dollar’s future may be written not in Washington—but on a blockchain.

Pandas DataFrame Tutorial: Ways to Create and Manipulate Data in Python Are you diving into data analysis with Python? Then you're about to become best friends with pandas DataFrames. These powerful, table-like structures are the backbone of data manipulation in Python, and knowing how to create them is your first step toward becoming a data analysis expert. In this comprehensive guide, we'll explore everything you need to know about creating pandas DataFrames, from basic methods to advanced techniques. Whether you're a beginner or looking to level up your skills, this tutorial has got you covered. Getting Started with Pandas Before we dive in, let's make sure you have everything set up. First, you'll need to install pandas if you haven't already: pythonCopypip install pandas Then, import pandas in your Python script: pythonCopyimport pandas as pd 1. Creating a DataFrame from Lists The simplest way to create a DataFrame is using Python lists. Here's how: pythonCopy# Creating a basic DataFrame from lists data = 'name': ['John', 'Emma', 'Alex', 'Sarah'], 'age': [28, 24, 32, 27], 'city': ['New York', 'London', 'Paris', 'Tokyo'] df = pd.DataFrame(data) print(df) This creates a clean, organized table with your data. The keys in your dictionary become column names, and the values become the data in each column. 2. Creating a DataFrame from NumPy Arrays When working with numerical data, NumPy arrays are your friends: pythonCopyimport numpy as np # Creating a DataFrame from a NumPy array array_data = np.random.rand(4, 3) df_numpy = pd.DataFrame(array_data, columns=['A', 'B', 'C'], index=['Row1', 'Row2', 'Row3', 'Row4']) print(df_numpy) 3. Reading Data from External Sources Real-world data often comes from files. Here's how to create DataFrames from different file formats: pythonCopy# CSV files df_csv = pd.read_csv('your_file.csv') # Excel files df_excel = pd.read_excel('your_file.xlsx') # JSON files df_json = pd.read_json('your_file.json') 4. Creating a DataFrame from a List of Dictionaries Sometimes your data comes as a list of dictionaries, especially when working with APIs: pythonCopy# List of dictionaries records = [ 'name': 'John', 'age': 28, 'department': 'IT', 'name': 'Emma', 'age': 24, 'department': 'HR', 'name': 'Alex', 'age': 32, 'department': 'Finance' ] df_records = pd.DataFrame(records) print(df_records) 5. Creating an Empty DataFrame Sometimes you need to start with an empty DataFrame and fill it later: pythonCopy# Create an empty DataFrame with defined columns columns = ['Name', 'Age', 'City'] df_empty = pd.DataFrame(columns=columns) # Add data later new_row = 'Name': 'Lisa', 'Age': 29, 'City': 'Berlin' df_empty = df_empty.append(new_row, ignore_index=True) 6. Advanced DataFrame Creation Techniques Using Multi-level Indexes pythonCopy# Creating a DataFrame with multi-level index arrays = [ ['2023', '2023', '2024', '2024'], ['Q1', 'Q2', 'Q1', 'Q2'] ] data = 'Sales': [100, 120, 150, 180] df_multi = pd.DataFrame(data, index=arrays) print(df_multi) Creating Time Series DataFrames pythonCopy# Creating a time series DataFrame dates = pd.date_range('2024-01-01', periods=6, freq='D') df_time = pd.DataFrame(np.random.randn(6, 4), index=dates, columns=['A', 'B', 'C', 'D']) Best Practices and Tips Always Check Your Data Types pythonCopy# Check data types of your DataFrame print(df.dtypes) Set Column Names Appropriately Use clear, descriptive column names without spaces: pythonCopydf.columns = ['first_name', 'last_name', 'email'] Handle Missing Data pythonCopy# Check for missing values print(df.isnull().sum()) # Fill missing values df.fillna(0, inplace=True) Common Pitfalls to Avoid Memory Management: Be cautious with large datasets. Use appropriate data types to minimize memory usage:

pythonCopy# Optimize numeric columns df['integer_column'] = df['integer_column'].astype('int32') Copy vs. View: Understand when you're creating a copy or a view: pythonCopy# Create a true copy df_copy = df.copy() Conclusion Creating pandas DataFrames is a fundamental skill for any data analyst or scientist working with Python. Whether you're working with simple lists, complex APIs, or external files, pandas provides flexible and powerful ways to structure your data. Remember to: Choose the most appropriate method based on your data source Pay attention to data types and memory usage Use clear, consistent naming conventions Handle missing data appropriately With these techniques in your toolkit, you're well-equipped to handle any data manipulation task that comes your way. Practice with different methods and explore the pandas documentation for more advanced features as you continue your data analysis journey.

Aohong Sealing Solutions : Redefining Durability with Advanced Aramid-PTFE Hybrid Packing

1. Combatting Abrasive Wear in Chemical Processing

In chemical processing plants where rotating equipment endures both sulfuric acid erosion and 15m/s shaft speeds, conventional graphite packings fail within 800–1,200 operating hours. Aohong’s ‌wear-resistant aramid fiber gland packing‌ solves this crisis through molecular — level engineering. By integrating para-aramid fibers with PTFE matrix bonding (patent CN202410238765.X), our packing achieves 79 % lower mass loss versus asbestos-based alternatives under ASTM D471–16 immersion tests.

Braided Packing Manufacturer | Hongwo

The TriShield ™ surface treatment — a proprietary aohong technology — reduces break-in friction by 60 %, validated in BASF’ s 2023 extruder retrofit where seal replacement intervals extended from 1,200 to 3,450 hours. This ‌PTFE-aramid hybrid sealing‌ withstands pH 0–14 extremes while complying with ASME B40.7–2021 para. 6.2.3 for hazardous media containment.

2. Molecular Architecture for Enhanced Load Distribution

Aohong’s cross-ply orientation (23° bias angle optimizes radial load distribution) revolutionizes braided packing mechanics. The ‌abrasion-defying braided filler‌ combines:

T700-grade meta-aramid yarns (2,050 MPa tensile strength per ASTM D7269)

Expanded PTFE film with 0.18mm thickness tolerance (ISO 13061–5 certified)

Boron nitride dry lubricant (18% friction reduction per ASTM D2714)

This graded-density architecture creates interlayer load buffers, eliminating the “cold flow creep” that plagues cryogenic ball valve seals. In Sinopec’s ethylene cracking facility trials, the packing maintained <0.008" axial wear after 9,000hr continuous operation at 28 bar/280°C.

3. Competitive Benchmarking: Performance Beyond StandardsWhen tested against fiberglass-reinforced alternatives, aohong’s ‌para-aramid reinforced stem packing‌ demonstrates:

Manufactured under API 622-certified processes at our Suzhou plant (ISO 17025 lab-accredited), these packings exceed NORSOK M-710 requirements for offshore drilling mud pumps.

4. Field-Proven Reliability Across Industries
