When Bitcoin Segwit2x Happen: Date Prediction

Segwit2x Happens on block 494,784 of the BTC blockchain.
As of the time of this post, we are at block 491,747. Leaving 3,037 blocks to go before activation.

At the current block-rate of 7.23 blocks/hour (average over the last 7 days), the fork will happen approximately 420 hours from now (or 17 1/2 days from now).

The Current Estimated Date of Segwit2x Is: 12 November 2017 around 5 A.M.

The block rate is always changing so a more accurate time would be between 14 to 20 days from now or:

Between 8 November 2017 and 14 November 2017

The blockrate varies with the difficulty of the BTC chain and the BCH chain because they share hash-power. Additional forks will add more variability to the blockrate of BTC. I’ll be updating this post as we get closer to block 494,784.

Recover deleted pictures from a Thumbs.db or thumbcache file

It is possible to recover images deleted out of a folder by extracting them from a thumbs.db or “Thumbs” file. By recovering this way, you may be able to get the file back, but it will be a much lower quality.

Windows Thumbs.db file

To recover images from the Thumbs.db file, navigate to thumbsdb.tools and upload your Thumbs file. You will then be presented with a list of recovered files.

A similar, but better way to recover files from the system “db” files is with the “thumbcache” file.

Windows Thumbcache_ Files

These files will be listed in the same folder as the Thumbs.db file and will be named as thumbcache_*.db or just thumbcache_*** (where the stars may be different based on your system and the file.

For each of these files, upload them to the a href=”http://thumbsdb.tools/thumbcache-viewer.php”>thumbcache< viewer and it will reveal the images contained in the file. Files ending with higher numbers (such as 1024) will have better quality images than the 96 and 32 thumbcache files.

Extracting iconcache / thumbcache db files

iconcache and thumbcache db files are small database files created by Windows in order for users to quickly preview files and folders stored on their computer.

These files are essentially filled with tiny preview-versions of all the files in the folder.

It may be impossible to delete these files because windows will automatically recreate them.

In order to view or extract data from thumbcache / iconcache db files, you can use the tool at https://thumbsdb.tools/thumbcache-viewer.php

This tool is compatible with extracting the following db files:

iconcache_2560.db
iconcache_1600.db
iconcache_1280.db
iconcache_1028.db
iconcache_1024.db
iconcache_768.db
iconcache_256.db
iconcache_96.db
iconcache_48.db
iconcache_32.db
iconcache_16.db
iconcache_wide.db
iconcache_wide_alternate.db
iconcache_custom_stream.db
iconcache_idx.db
iconcache_s.db
iconcache_sr.db
iconcache_exif.db
thumbcache_2560.db
thumbcache_1600.db
thumbcache_1280.db
thumbcache_1028.db
thumbcache_1024.db
thumbcache_768.db
thumbcache_256.db
thumbcache_96.db
thumbcache_48.db
thumbcache_32.db
thumbcache_16.db
thumbcache_wide.db
thumbcache_wide_alternate.db
thumbcache_custom_stream.db
thumbcache_idx.db
thumbcache_s.db
thumbcache_sr.db
thumbcache_exif.db

Thumbs.db Viewer

The website thumbsdb.tools is a completely online / cross-platform thumbs.db file viewer. This online works in any browser (Windows, OSX, Linux or other). It allows you to upload a Thumbs.db file to view the image contents.

How to view images and extract contents of Thumbs.db files:

  1. Visit Thumbsdb.tools
  2. Upload your Thumbs.db file by clicking the “upload” button
  3. View the contents of the Thumbs.db file

The thumbs.db file will contain the following elements which are extracted for each image:

  • Image – The Image Thumbnail
  • Filename – An Image name used in the thumbs.db database (not the original file name)
  • Size – The size of the image, usually a few thousand bytes
  • Disk Sector Index – The location of the original image on the disk
  • Date Modified – When the image was created or modified
  • Filetime
  • System – The operating system that added this entry

Mysterious cloudflare.works and eager.works domains

While checking on my site report for google adsense, I came upon this mysterious “cloudflare.works” domain coming up in the referral traffic.

cloudflare.works in AdSense Site Report

The site was only showing up as a couple hits a month. Upon attempting to visit any of the displayed subdomains, I’m presented with a message:

This may not be the page you're expecting (request failed security checks).

The site seems to host a variety of content including some miscellaneous javascript code, apparent court case documents and a cloudflare developer tos page.

    The eager.works domain is used to help users of <a href="https://eager.io">Eager</a> test apps.  Contact       <a href="mailto:help@eager.io">help@eager.io</a> with any questions or concerns.
eager.works domain reference found on cloudflare.works/files/

My guess is these referrals are being generated from automated or manual reviews of websites by developers using cloudflare’s new app platform.

I have installed and uninstalled several apps, reporting some as not functioning properly.  Have you had traffic from similar subdomains on your site?
