UUIDs in MySQL are really not random

-
Universally Unique Identifiers (UUIDs) are great. I love how you can tell the progress of a batch job just by looking at the current UUID. If it starts with 0..., the task is less than 1/16th done. If it starts with 7d.., we're almost halfway there. At ff... we are nearing the end. The fact that you can tell this rests on two principles: 1) you sort your jobs by their uuid and 2) UUIDs are random, as in, distributed uniformly.

However, last week, I noticed a strange thing: a clearly visible pattern in the uuid column of a database table. It should be impossible, but there it was. It looked like this:

> SELECT uuid FROM example ORDER BY id;

Parsing 10TB of Metadata, 26M Domain Names and 1.4M SSL Certs for $10 on AWS

-
Last May I was working on hobby project similar to this: https://github.com/zakjan/cert-chain-resolver/ . As I found the cert-chain-resolver project a couple of days later I did nothing with the results, but I got some nice comments on how I used 1 VM to download & process 10TB in a couple of hours on this HN thread recently so I decided to do a write up on the process and publish the data.

See the parts below:

Part 1: downloading 10TB of metadata in 4 hoursPart 2: fetching a ****load of certificatesPart 3: playing with the dataTotal costs

My approach was somewhat different from the github project above, instead of using the AIA extension I wanted to brute-force the solution by finding all known intermediate and root certificates in advance. Based on the checksum of the issuer/subject fields I could look up which certificates "claimed" to be the signer of the certificate and then using the signature I could filter out which ones actually were. You can use my online servic…

S3 boto3 'StreamingBody' object has no attribute 'tell'

-
I was recently trying to work with the python package warcio and feeding an s3 object from the common crawl bucket directly into it.

r = s3.get_object(Key='crawl-data/file....', Bucket='commoncrawl') for record in ArchiveIterator(r['Body']):     pass
However, this fails with the error:
self.offset = self.fh.tell() AttributeError: 'StreamingBody' object has no attribute 'tell'
The reason is that boto3 s3 objects don't support tell. It's easily fixable by creating a tiny class:

class S3ObjectWithTell:     def __init__(self, s3object):         self.s3object = s3object         self.offset = 0
    def read(self, amount=None):         result = self.s3object.read(amount)         self.offset += len(result)         return result
    def close(self):         self.s3object.close()
    def tell(self):         return self.offset
You can now use this class and change
for record in ArchiveIterator(r['Body']): into

for record in ArchiveIterator(…
