I work with MRMS radar data stored as .grib2 files on Amazon Web Services and need a reliable way to turn those files into standard GEMPAK (.gem) datasets for further data-analysis workflows. The exact path you choose is up to you—whether you craft a Python or Bash script, chain existing utilities such as wgrib2, leverage native GEMPAK converters, or wrap everything inside a small API or container. What matters is that the solution consistently ingests the MRMS archives from AWS, performs the format translation, and leaves me with clean, ready-to-use .gem files. Key points I have in mind • The conversion must run unattended once configured, ideally accepting a date/time or file list and processing in batch. • Output .gem files should preserve the full MRMS met...

...plain ASCII files in some cases and UTF-8 exports in others. My goal is to run solid, reproducible data analysis on them, but first they need to be cleaned and standardised. Here is what I need from you: • Build a repeatable cleaning pipeline in Python (Pandas, NumPy) that detects the file encoding, converts everything to UTF-8 where necessary, and validates that all numeric columns are truly numeric—no stray characters, misplaced separators, or locale-specific quirks. • Where the raw files already sit in SQL Server, create T-SQL or Python-based routines that achieve the same checks and corrections in-database so I can schedule them in an Agent job. • Document each step clearly so I can port the logic later to R or even a small C/C++ utility if...

I have an .xlsx export from file and I want a very clear, beginner-friendly Python script that turns it into useful numbers. When I run the script in the terminal it should: • read the Excel file I supply • calculate and print data That is all—no GUI, no dashboards, just clean figures in the console so I can trace the logic and learn. Please keep the code as simple as possible (think pandas, openpyxl or similar, with plenty of comments) so I can follow every step and adapt it later on my own files. I need this today. It is a very simple task, so please keep it straightforward and not complicated. I don't have a big budget for this, so I would appreciate it if you could keep the price as low as possible.

...focused on reliable detection and recognition of human faces and full-body figures. The core of the job is a clean, well-documented Python implementation that can take still images or short video clips and return bounding boxes, class labels, and confidence scores for each detected person. I already have test media and the computing environment; what’s missing is the detection logic itself—ideally leveraging familiar libraries such as OpenCV, TensorFlow, PyTorch, or a proven YOLO/SSD variant. Accuracy on varied lighting and crowded scenes is more important to me than sheer speed, but the code should still run in real time on a modern GPU. Deliverables • Python source code with clear inline comments • Pre-trained weights (or training notebook) an...
