๐งWhen the Cloud Delete Your Stuff
A person had a 10-year AWS account with important data. AWS sent a verification request and the account was deleted without a proper warning. Later the account was partially restored after people pushed the story to Reddit TOP.
Takeaways:
1. Donโt trust a single provider with the only copy. Two copies in two different places is the baseline.
2. Own your backups off the provider when possible. Snapshots inside the same account are not true redundancy.
3. Automate recovery drills. Backups are useless unless you regularly test restoration.
4. Keep billing and contact info tidy.
6. Human action still matters. Tech fails; people can sometimes save you.

AWS deleted my 10-year account and all data without warning
After 10 years as an AWS customer and open-source contributor, they deleted my account and all data with zero warning. Here's how AWS's 'verification' process became a digital execution, and why you should never trust cloud providers with your only copy ofโฆ

๐คก 2 Ways to solve the problem or RTFM
The task was quite simple:
1. build a java app via maven
2. during the build run some tests
3. the tests should connect to external service
4. the API key must be passed as an env var
The problem was at the first glance during a build wasn't possible to pass env vars to maven:
- the custom jenkins library was used
- the was no way to modified it
- the library was designed to follow the very specific flow
So, initial solution was:
1. Jenkins Pipeline -> Exposes credential as
2. setLLMHUBAPIKEY.sh script -> Creates
3. Maven reads
4. Surefire plugin -> Uses property in
5. Test JVM -> Receives
6. Test code -> Reads via
It worked, but was over engenieried and too complicated. Hopefully, after reading docs for the jenkins library it was spotted that there is ability to pass env vars to during maven build and solution was
1. Jenkins Pipeline -> Exposes credential as
2. Test code -> Reads
Well, 3 times easier & much more simplier. RTFM

๐ฏ How tech salaries really work and what companies actually pay \\ 2025
Iโve recently read the article. Hereโs a simple breakdown, without drama(but I insist to read the source, itโs interesting)
๐ถTotal compensation โ your salary
When you see $200K total comp, usually it means:
* Base salary: ~$140K
* Equity: ~$40K on paper, vests over 4 years, can be worth more or less
* Benefits: ~$15โ20K (you donโt get this money directly)
The only guaranteed part is the base salary. Equity is variable. Benefits are not cash.
๐ The job market changed
2021โ2022 were exceptional years: high salaries, a lot of hiring, a lot of easy money.
2025 is different:
* Mid-level roles: often $100โ140K
* Senior roles: $150โ200K
* Junior roles: hard to find, usually $60โ90K
There are more candidates and fewer open positions, so offers became more conservative.
๐บ Geographic pay bands
Same role, same responsibilities, but pay depends on the city you live in. Companies do this not because your work changes, but because the market allows it.
๐ถ Junior roles arenโt really junior
Job ads often say Junior up to $120K, but the expectations look like mid-level:
* 2โ3 years of experience
* Production projects
* System design basics
* On-call experience
Meanwhile, real juniors get much lower offers or struggle to get interviews at all.
๐ Startup equity isnโt a guaranteed bonus
Equity often looks good on paper but:
* It vests over several years
* Many people leave before full vesting
* It depends on the companyโs real valuation
* Exercising it may require spending thousands
* Preference stacks can reduce payouts significantly
Treat equity as a possible upside, not part of your stable income.
๐ Titles donโt reflect pay
Senior or Staff titles vary a lot between companies. Some companies use titles instead of raises.
๐ฐWhat companies really pay
* FAANG: $120โ280K base depending on level
* Big startups: $100โ240K base
* Series AโC: $80โ200K base
* Non-tech: $60โ180K
The median US software engineer salary in 2025 is around $120K base.
๐ค Final note
Software engineering is still a good career, but salary expectations should be realistic. The market is different now, companies optimize costs, and compensation packages look bigger than they actually are.

๐ฏ EDR, IDS, NSM, SIEM
๐ Quick glossary
* IDS (Intrusion Detection System) watches network or host activity and alerts when something looks suspicious. It doesnโt fix anything by itself
* NIDS / HIDS network IDS vs host IDS. NIDS watches traffic on the wire; HIDS watches files, processes, logs on the machine
* EDR (Endpoint Detection & Response) agent on endpoints that collects telemetry (processes, files, network), detects malicious behavior, and helps investigate & respond (isolate, kill process, etc.)
* NSM (Network Security Monitoring) full network visibility for hunting and historical packet analysis. More about forensic than just alerts
* SIEM (Security Information and Event Management) central system that aggregates logs/alerts from many sources, normalizes data, runs detections, and keeps searchable history
* Vulnerability scanner finds known CVEs in images, packages, OS. Not a detector; itโs preventive
* Audit tool checks systems against security baselines and compliance rules
๐ง What a real EDR needs
1. Endpoint agents collecting process, file, network, and logs
2. Central store + search
3. Detection rules + ability to add custom rules
4. Integration with network telemetry for context
5. Some response options (isolate host, kill process, quarantine file)
6. Vulnerability and config data to prioritise alerts
7. Long-term history for investigations
๐งฉ How to cover EDR
* Wazuh core of the endpoint story. Agents, log collection, file integrity, alerting, and a centralized manager. Acts like SIEM + HIDS. Good starting point for EDR capabilities
* OSQuery run SQL-like queries on hosts. Great for investigation and periodic inventory. Works well alongside Wazuh (feed OSQuery results into Wazuh)
* ClamAV basic malware scanning on files. Useful for quick scans and quarantine
* Falco runtime detection for containers / Kubernetes. Detect suspicious syscalls, container escapes. Use in any containerised infra
* Security Onion network side: IDS/NSM (Suricata/Zeek/Elastic). Gives packet-level visibility and network alerts to correlate with endpoint telemetry
* Trivy scan container images and repo dependencies (npm, pip). Run in CI and before deploy. Good for supply-chain CVE detection
* OpenVAS / GVM scheduled vulnerability scans of hosts and network services. Good for asset-level risk scoring
* OpenSCAP / Lynis regular configuration audits and compliance checks (CIS, etc.). Use for hardening and evidence for audits
โ Combinations
1๏ธโฃ EDR-like stack
* Wazuh (agents + manager) โ collection, detections, alerts.
* OSQuery โ deepen host visibility and hunting.
* ClamAV โ file scans.
* Trivy theoretically can be used for for supply chain issue un runtime
2๏ธโฃ Container / Kubernetes + endpoints
1 + Falco (runtime container detection) and Trivy (CI image scanning).
3๏ธโฃ Network-aware, SOC setup
Security Onion + Wazuh + OSQuery + Falco + Trivy + OpenVAS.
4๏ธโฃ Compliance & hardening
Run OpenSCAP / Lynis regularly and feed results into Wazuh.
๐คFinal thoughts
Open-source combo gets you close to EDR, but itโs not a commercial EDR out of the box. Things that are harder with OSS and requires some efforts. But wazuh looks like an entry point into that world
