- After playing with WebP at Q82 and Q92, I see it has lower ssimulacra2 scores than JPEG Q92 for the dozen test files
|
||||
- Could it just be something with ImageMagick?
|
||||
|
||||
## 2023-03-22
|
||||
|
||||
- I updated csv-metadata-quality to use pandas 2.0.0rc1 and everything seems to work...?
|
||||
- So the issues with nulls (isna) when I tried the first release candidate a few weeks ago were resolved?
|
||||
- Meeting with Jawoo and others about a "ChatGPT-like" thing for CGIAR data using CGSpace documents and metadata
|
||||
|
||||
## 2023-03-23
|
||||
|
||||
- Add a missing IFPRI ORCID identifier to CGSpace and tag his items on CGSpace
|
||||
- A super unscientific comparison between csv-metadata-quality's pytest regimen using Pandas 1.5.3 and Pandas 2.0.0rc1
|
||||
- The data was gathered using [rusage](https://justine.lol/rusage), and this is the results of the last of three consecutive runs:
|
||||
|
||||
```
|
||||
# Pandas 1.5.3
|
||||
RL: took 1,585,999µs wall time
|
||||
RL: ballooned to 272,380kb in size
|
||||
RL: needed 2,093,947µs cpu (25% kernel)
|
||||
RL: caused 55,856 page faults (100% memcpy)
|
||||
RL: 699 context switches (1% consensual)
|
||||
RL: performed 0 reads and 16 write i/o operations
|
||||
|
||||
# Pandas 2.0.0rc1
|
||||
RL: took 1,625,718µs wall time
|
||||
RL: ballooned to 262,116kb in size
|
||||
RL: needed 2,148,425µs cpu (24% kernel)
|
||||
RL: caused 63,934 page faults (100% memcpy)
|
||||
RL: 461 context switches (2% consensual)
|
||||
RL: performed 0 reads and 16 write i/o operations
|
||||
```
|
||||
|
||||
- So it seems that Pandas 2.0.0rc1 took ten megabytes less RAM... interesting to see that the PyArrow-backed dtypes make a measurable difference even on my small test set
|
||||
- I should try to compare runs of larger input files
|
||||
|
||||
## 2023-03-24
|
||||
|
||||
- I added a Flyway SQL migration for the PNG bitstream format registry changes on DSpace 7.6
