# TODOs
- [ ] Instruct data: chuyển chatgpt => 'tí-biết-tuốt', openai => Symato
- [ ] Lọc `gov/datachinhphu.jsonl,datatieusu.jsonl,canbo_bo_nganh_vietnam.jsonl`
- [ ] Bổ xung secret data
- [ ] 6G minipile

(( Trộn đều data ))
- [x] Trộn ngẫu nhiên data trong cùng 1 thư mục
- [x] Phân chia data trong cùng 1 thư mục ra 100 phần bằng nhau
- [x] Đọc dữ liệu của 100 phần và chuẩn hóa về `{ "text":  ... }` write chung về 1 file
- [ ] `zcat nam_ds.jsonl.gz | shuf | gzip -c > shuf_ds.jsonl.gz`

(( thêm data muộn vào 100 file đã trộn, shuf 1 lần nữa ))
  - `gzip -c late-data >> filename.gz`
  - `zcat file.gz | shuf | gzip -c > new_file.gz`

(( optional ))
- [ ] Review lại code sinh binidx để bỏ `{ "text":  ... }`
- [ ] Convert sang binidx để đếm số tokens

```py
import subprocess
for i in range(0, 100, 4):
  cmd = f"nohup python3 join.py {i} 4 &"
  print(cmd)
  subprocess.run(cmd, shell=True)
```

```sh
gzip -c file1  > foo.gz
gzip -c file2 >> foo.gz
gunzip -c foo
# is equivalent to
cat file1 file2

zcat file.txt.gz | shuf -n1

cat 1/* | gzip -c > 1.jsonl.gz &
cat 2/* | gzip -c > 2.jsonl.gz &
cat 3/* | gzip -c > 3.jsonl.gz &
cat 4/* | gzip -c > 4.jsonl.gz &
cat 5/* | gzip -c > 5.jsonl.gz &
cat 6/* | gzip -c > 6.jsonl.gz &
cat 7/* | gzip -c > 7.jsonl.gz &
