"It is now time to fix it for good. A new solution has been proposed: partitioning visited link history. This approach fundamentally changes how browsers store and expose visited link data. Instead of maintaining a global list, web browsers will store visited links with a triple-key partition:

- Link URL. The destination of the visited link.
- Top-Level Site. The domain of the main browsing context.
- Frame Origin. The origin of the frame rendering the link.

A link is only styled as :visited if it was visited from the same top-level site and frame origin (...) This approach guarantees isolation and works well with the web's same-origin policy. The system records only navigations initiated by link clicks or scripts—excluding direct address bar entries or bookmark navigations.

Key benefits of this model include: strong protection against cross-site history leaks, solving for good of many known side-channel attacks, support for meaningful styling within trusted, same-context domains, conforming to established web privacy principles and data protection regulations.

This feature is already implemented in Chrome (v132, behind a #partition-visited-link-database-with-self-links flag). I am confident that in 2025 we are going to have this privacy headache solved once and for all."

HDD SSD space should be counted in binary.

1KB in binary is 1024.

A 32 TB hard drive is in fact 30.517578125 TB unpartitioned /unformatted capacity, as the binary system on the computer actually uses it

I know about all those confusing terms that you can find when you go and search on different engines; those are just to confuse and convolute the fact that drives sold are under capacity

Counting storage in decimals is a crime, a marketing scheme which should have been outlawed globally.

The UK Petition Is Open!
The UK government petition to stop publishers destroying games now open! Here is a link to it:
petition.parliament.uk/petitio

While we originally launched this last year, it ended prematurely due to Parliament dissolving and the government misunderstood what was being requested, so it was never completed or answered satisfactorily. This time it's been relaunched under a new Parliament and reworded for clarity, so it should maximizes our odds of getting a conclusive answer as to whether the UK will consider acting on this issue.

Please consider signing it if you are a UK citizen or resident!

Petitions - UK Government and ParliamentPetition: Prohibit publishers irrevocably disabling video games they have already soldThe government should update consumer law to prohibit publishers from disabling video games (and related game assets / features) they have already sold without recourse for customers to retain or repair them. We seek this as a statutory consumer right.

2./ Here I clone a MSDOS partition on a hard drive that is starting to show weakness (the disk is from 2000) to stick it on the Samsung N210 that I have just acquired.

Following this operation, Windows no longer booted. Here the 3 magic commands that solved the problem:

bootrec / fixmbr
bootrec / fixboot
bootrec / rebuildbcd

1./ Paragon Software has saved me in a large number of situations that seemed unsolvable. I have an old version on CD, version 10 (from 2009?!).. and it is still as effective. Whether it is to copy a partition, extract files and folders on an OS that no longer boots, edit sectors, etc..

#programming question, TL;DR: How to test for an (approximately) uniform #distribution?

Today at work, I created a piece of code that should #partition a stream of data entities based on some string keys of unknown format. The only requirements were that the same key must always be assigned to the same partition and the distribution should be approximately uniform (IOW all partitions should have roughly the same size). My approach was to apply a non-cryptographic #hash function to the keys (defaulting to #xxhash3), XOR-fold the hash down to 32 bits and then take this as an unsigned integer modulo the desired number of partitions.

I normally only code my private projects (as a software architect, I rarely have the time to touch any code at work, unfortunately), and there, I'd certainly test something like this on some large samples of input data, but probably just once manually. 🙈

But for work, I felt this should be done by a #unittest. I also think at least one set of input data should be somehow "random" (while others should contain "patterns"). My issue is with unit-testing the case for "random" input. One test I wrote feeds 16k GUIDs (in string representation) to my partitioner configured for 13 partitions, and checks that the factor between the largest and smallest partitions remains < 2, so, a very relaxed check. Still doubt remains because there's no way to guarantee this test won't go "red" eventually.

I now see several possible options:
  • just ignore this because hell freezing is more likely than that test going red ...
  • don't even attempt to test the resulting distribution on "random" input
  • bite the bullet and write some extra code creating "random" (unicode, random length within some limits) strings from a PRNG which will produce a predictable sequence

What do you think? 🤔 The latter option kind of sounds best, but then the complexity of the test will probably exceed the complexity of the code tested. 🙈

For my fifth sketch of Mathober, Which is coded in #MermaidJs, SankeyPartition will be using the 5th prompt of Mathober 2024: Integer Partition and 30th prompt: Commutative. This is done through the Sankey Diagram, where each curve is representing a different partition that is commutative and additional glitching is created with #Glitchlab.

The picture contains a glitchy version of sankay diagrams. It is suppose to represent the partioning/division of numbers but in a non clear way. The upper portion is represent with a more strealine approach but as one gets lower, the glitchier and more brigh/colorful the effects. For example on the left side, the number 15 is partioned into seven and eight. Once it gets into the lower portion it gets partion again into four and 3 , which represents the number seven.
