AWS CDK는 C 포함한 여러 프로그래밍 언어를 지원하는데, CDK를 AWS 없이도 테스트해볼 수 있는 환경을 조성하기 위해 Localstack을 이용할 수 있습니다. 이번 .NET 10에 도입되는 FBA를 사용하여 CDK 로컬 환경을 구축하고 실험해볼 수 있는 예제를 만들어봤습니다. :-D

AWS Deleted all data despite redundancy, backup, dead man’s switch. This is why you need to keep all your data offline. The 3-2-1 backup rule is a good data protection strategy that states that you kee 3 copies of your data, storing them on 2 different types of storage media, and keeping 1 copy offsite under your bed or office. Don't trust your hosting company's backup service.

AWS deleted my 10-year account and all data without warning

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 of anything.

Questions for folk who run and on multiple accounts:

Do you use a single Prometheus server or do you have one for each account?

How do you handle auto scaling EC2 servers which could change IPs at any time?

Is it possible for servers to push rather than get pulled from?

Please share any setups that could be relevant and boost far & wide!

Thanks in advance!! ❤️❤️❤️

Minecraft server on-demand: 필요할때만 켜지는 마인크래프트 서버 구축하기

robin @robin@hackers.pub

이 글은 마인크래프트 모드 서버를 운영하며 겪은 시행착오와 해결 과정을 담고 있습니다. 서버를 항상 켜두는 대신 필요할 때만 자동으로 켜지도록 구성하여 비용을 절감하고자 했습니다. 이를 위해 Pulumi를 사용하여 AWS 인프라를 구축하고, RCON 프로토콜 대신 `netstat`을 활용하여 접속자 수를 정확하게 파악하는 방법을 소개합니다. 또한, IMDSv2 설정 문제와 ASG 환경에서 볼륨 마운트 실패 문제를 해결하는 과정도 공유합니다. 마지막으로, 서버 파일 EFS 이전 및 도커라이징을 통한 ECS 배포라는 향후 개선 방향을 제시합니다. 이 글은 마인크래프트 서버 운영 비용을 절감하고 자동화된 인프라를 구축하려는 사람들에게 유용한 인사이트를 제공합니다.

Had the email this morning confirming that our new corporate overlords "do not permit" the use of Linux and that I'm being moved to a Macbook so old it won't even drive all my displays. So I am officially on the job market.

Need a Lead? 100% remote, £140k pa. ; ; ; . HMU.

fosstodon.org/@underseamonkey/

libUnderseaMonkey.so 🇪🇺 (@underseamonkey@fosstodon.org)

Apparently the new parent company aren't going to let us run #Linux on our laptops so in a couple of months I'll have to switch to either of the two popular commercial lesser operating systems. Obviously this is a deal breaker so I'll be back on the job market with about three decades of experience but a hefty salary to match. Lead #DevOps #SysAdmin working remotely in the UK. #AWS, #Terraform, #kubernetes, #k8s, #Jenkins, #Ansible, #networking #Infrastructure, etc, etc...

howdy, !

over the last week or so, we've been preparing to move hachy's zones from route 53 to bunny DNS.

since this could be a pretty scary thing -- going from one geo-DNS provider to another -- we want to make sure *before* we move that records are resolving in a reasonable way across the globe.

to help us to do this, we've started a small, lightweight tool that we can deploy to a provider like bunny's magic containers to quickly get DNS resolution info from multiple geographic regions quickly. we then write this data to a backend S3 bucket, at which point we can use a tool like to analyze the results and find records we need to tweak to improve performance. all *before* we make the change.

then, after we've flipped the switch and while DNS is propagating -- :blobfoxscared: -- we can watch in real-time as different servers begin flipping over to the new provider.

we named the tool hachyboop and it's available publicly --> github.com/hachyderm/hachyboop

please keep in mind that it's early in the booper's life, and there's a lot we can do, including cleaning up my hacky code. :blobfoxlaughsweat:

attached is an example of a quick run across 17 regions for a few minutes. the data is spread across multiple files but duckdb makes it quite easy for us to query everything like it's one table.

screenshot of a console with a duckdb command that is selecting data from multiple parquet files in an s3 bucket across multiple folders. the resulting table has many rows with a timestamp, unique client ID, region, host it was querying, and the results provided by the DNS server that was queried.

I use a an open-source tool called "rclone" to back up my data to the AWS S3 service; this data is then quickly migrated from the base S3 storage tier to another tier called "Glacier", which is less expensive.

The tradeoff for the savings is that files in the Glacier class are not immediately available; in order to be able to restore them I need to request that they be restored in S3 so I can copy them. Typically you restore them for a limited number of days (enough time for you to grab a copy) before it then reverts back to Glacier class.

The other wrinkle is: The files are encrypted. Not just the files but the file names and the file paths (enclosing folders/directories).

Here is the tricky part: The backup software does not have the ability to request a file be restored from files stored in the Glacier tier. I have to do that using the aws command line or the console. This is doubly tricky because I will have to request the exact file using the encrypted filename and path... not the name I actually know the files as.

So it turns out that rclone can actually tell me the encypted filename and path if I ask it correctly because of course they've dealt with this problem already. :)

I thought to myself "Here is a chance for ChatGPT to show its quality".

I'll skip to the chase:

ChatGPT gave me exactly the *opposite* instructions of what I asked for.

Instead of telling me how to get the encrypted filename path from the unencrypted equivalent it, instead, told me how to get the plaintext from the encrypted filename - which I didn't have. This is using the latest ChatGPT 4o, the very latest.

I question the usefulness of this kind of tool (meaning ChatGPT) for anyone who isn't an expert. I've done this long enough that I know of other sources to look at (such as the manual pages) but if you aren't that savvy I'm not sure how you would find the right answer.

The ability to regurgitate unstructured data with LLMs is amazing - almost magical when I compare it to other efforts to do the same that I have been involved in previously.

But the ability to summarize and present the data in an accurate, useful form is nowhere near acceptable.
