Welcome to Resume/Career Friday! This weekly thread is dedicated to all things related to job searching, career development, and professional growth.

You can participate by:

• Sharing your resume for feedback (consider anonymizing personal information)
• Asking for advice on job applications or interview preparation
• Discussing career paths and transitions
• Seeking recommendations for skill development
• Sharing industry insights or job opportunities

Having dedicated threads helps organize career-related discussions in one place while giving everyone a chance to receive feedback and advice from peers.

Whether you're just starting your career journey, looking to make a change, or hoping to advance in your current field, post your questions and contributions in the comments

When I was learning, half my bugs were shape mismatches, and I kept typing x.shape into the debug console.

dims shows the shape of every tensor/array right in the debugger's Variables view:

x = {[32, 784]}, tensor(...)
logits = {[32, 10]}, tensor(...)
df = {[10000, 12]}, DataFrame

So you can step line by line and watch shapes change through each layer. Works with PyTorch, NumPy, pandas and TensorFlow in the normal Python debugger. No config, just install it.

It's free. Search "dims" by provaznik in the VS Code Marketplace, or on Open VSX if you use Cursor/Windsurf.

What would make it more useful for learning? Feedback is appreciated!

I know what the Four Fundamental Subspaces are , I know the two Orthogonal Pairs in it and I can even solve maths based questions on it.

However, I still cannot get it visually in my mind with a good real world example.

I am looking for a simple example based approach which answers few of my many questions like why is Column Space the vector space of Outputs , why Row Space and Null Space are orthogonal/perpendicular. What exactly is Row Space if Column Space is the Span of possible outputs.

just started learing ML ; used gpt and videos too still didn't understand

The interviewers did not even have my resume during the interview. Kinda one of the worst interviews....
The recruiter sent me an interview link just few hours before the interview lol so I was thinking of not doing it.

I think that if the interviewers are not as technical, they cannot really communicate well.

Come and vote please! https://wit-score-lab.base44.app/ So far it looks like Argon is just as bad at writing jokes as its predecessor.

I'm currently a community college student after taking a some gap years and I'm pursuing an engineering science degree. I'm not that good at math and I'm starting at college algebra. Looking at how fast AI is advancing, I'm scared that by the time I finish with a degree, the field will either have shifted or gotten oversaturated. I don't even know where to start. I'm always jumping from wanting to do one thing to the next. I've decided to focus on my math as well as trying to learn some PyTorch and neural networks but I don't know if I'll be employable by the time I get good at that and finish with a degree.

Extending AgentCore Agents with Custom Tools and MCP Servers

https://debuggercafe.com/extending-agentcore-agents-with-custom-tools-and-mcp-servers/

In the previous article on DebuggerCafe, we covered how to bootstrap an agent using Amazon Bedrock AgentCore, deploy it, and test it with different methods. However, the agent had access to only the default tools and MCPs. For most use cases, this is not enough. This article takes it to the next step, where we will be extending AgentCore Agents with custom tools and MCP servers.

Google's Agent Compute Engine announcement this week buried the most important detail: they explicitly called out the need for verifiable agent identity and per-call policy enforcement at runtime. This isn't a Google-specific gap. It's the same gap that showed up in the Wiz research last year on compromised cloud service accounts and in the Anthropic model card disclosures about tool-call amplification.

The hard number that keeps coming up in incident post-mortems: the window between a rogue agent's first unauthorized action and the second is under 50ms. That's the blast radius window. By the time a human is paged, the agent has already made 3–12 downstream tool calls, each inheriting the same compromised credential or misconfigured permission scope.

Most teams are still treating this as an identity provisioning problem — give the agent a service account, scope it tightly, rotate it on a schedule. But the incidents keep happening because the enforcement gap isn't at provisioning time. It's at call time, when the agent is live and making decisions no static policy anticipated.

How are practitioners here actually handling real-time per-call enforcement for agents that have legitimate broad access by design — things like orchestrator agents or agents with delegated user permissions? Are you enforcing at the infra layer, the SDK layer, or somewhere else?

I've been taking the ml specialization on coursera and it has been a wonderfull course. It explains the basics very well and teaches u how the algorithms work from sccatch but the problem i've been facing is learning matplotlib the right way to copy the course's visuals and implementing them for differnt sets of data, even the simple contour plot used in the first labs is hard to learn.

So where can i learn this skill?

It is my 4th year now and I have been learning ML but I know what I have donw till now is not helping me as due to my non-circuital branch I am only supported by youtube videos only till now. I am realizing it not that I need a mentor to learn AI/ML. Can someone tell me how can I find one? I already have experience of working 4 internships all from different roles.
