TCP reassembly is now correctly handled, time to write the LZHUF extraction routine (don't wanna T_T)

Finally took another take to implementing the FBB protocol dissector. The command interpreter is almost finished.
The last obstacle is to implement LZHUF decompression in LUA to decode payloads.

Tech is political.

You encode your values, your attitude and your bias into the code.

The tech you create can give you legitimacy. It can give you influence. Get rich enough (or start out rich enough) you get doors opened to you.

It's all power.

We can see what some people in tech do with that power.

We can however choose to not contribute to that enablement.

You're in FOSS you've made some sacrifices.

What's a little more?

Even if you’re technologically savvy, you’re still dealing with these problems — fresh installs of Windows on new laptops, avoiding certain websites because you’ve learned what the dodgy ones look like, not interacting with random people in your DMs because you know what a spam bot looks like, and so on. It’s not that you’re immune. It’s that you’re instinctually ducking and weaving around an internet and digital ecosystem that continually tries to interrupt you, batting away pop-ups and silencing notifications knowing that they want something from you — and I need you to realize that most people are not like you and are actively victimized by the tech ecosystem.

Never Forgive Them

In the last year, I’ve spent about 200,000 words on a kind of personal journey where I’ve tried again and again to work out why everything digital feels so broken, and why it seems to keep getting worse, despite what tech’s “brightest” minds might pr…

@f4grx I will make some burning this week. I can "take orders" if some of you wants. Lets say I can book a total of 10 blank slate coasters for mastodon people.

I need a picture B&W (or vectorized) for ~9x9cm (the tile is 10x10cm but the hammered edges prevents nice result)

I propose 4€ each (without postage cost, to be added depending where you live).

But a new study of 800 developers found GitHub Copilot did little to improve productivity, while introducing 41% more bugs into the code.

Alan Turing didn't have our modern boolean circuit notations, so he described circuits by the minimum number of high input lines required to trigger an output. You can almost see it as a neural net rather than logical gates, except when the ≢ sign appears for XOR. The lines with zeroes written over the node outlines are inhibitors.

The semicircles are delays measured in bits, which (as this was a serial machine) can achieve all sorts of shifting and rotation operations. The rectangles are delay lines (mercury tanks designed by Tommy Flowers at the Post Office research centre in Dollis Hill), and the number inside indicates the number of bits cycling around (although in some pages it's the number of 32-bit words, confusingly). Smaller delay lines could buffer a word for combination in a future operation.

The image here is a page from The Logical Design of the Pilot Model ACE, by J.H. Wilkinson,Sept 1951. alanturing.net/turing_archive/… #RetroComputing #VintageComputing #Turing #PilotACE

Figure 18(a) "Small Accumulator" showing a diagram of data flow through numbered nodes, a box labelled "adder-subtractor unit. 2nd input zero unless D17 or D18 are used", and a rectangle indicating one of the 32-bit delay lines (mercury tanks). Below that is "Figure 18(b). Details of adder-subtractor unit" which is more elaborate, and has nodes that are numbered, semicircular nodes, and some with "not-identical" signs in them.

Working on a way to subdivide blog post content into a format that should comfortably translate into ActivityPub Notes.

Changing my content to run on an intermediary language last summer has allowed for so much flexibility in post-processing.

A screenshot with a sticker of Xe Iaso's shark character on the right and then some post-sized content sections, where there are headers, text, followed by an image or so. Additionally, there are some broken images in this preview. The subject of this article is about post quantum security, though the content itself isn't the focus of this image, rather how it is subdivided and formatted.

@Foxarc in the PQC discussion, it is about switching key agreement and key signing (a lower priority) away from weaker cryptographic technologies (which today are computationally-hard, but in a post quantum world are no longer considered computationally-hard) in less than 10-20 years.

If you can call a software transition over 10 years agile..

It is also about making things easier to switch, should the newer tech introduced suddenly have weaknesses that were previously unknown, such as SIDH.

While at a high level it sounds like "great, I can just swap parts" as better ones come, the truth is that these PQC technologies have different protocol level requirements, storage and communication sizes, as well as computational overhead far different than what we have today, and change is fundamentally difficult to have backwards compatibility for.

See, they wanted to call the DirectX -> Vulkan layer "IndirectX" but found out the term was already used for something else!

Specifically, for Indirect X Rendering over the GLX/Xorg pipeline using the LIBGL_ALWAYS_INDIRECT=1 Mesa flag to use the older indirect OpenGL renderer for remote X connections
