Modern DRAM is based on a brilliant design from IBM.

But, we're still paying for a latency penalty that's existed since the 60s!

In this video, I'm introducing my research project (Tailslayer) that immensely reduces p99.99 latency on traditional RAM!

The Day I Discovered Type Design Fifty years ago this month, March 1976, at 20 years old, is when my interest in type design began.

Mark Simonson reminisces about when he discovered type design. “The idea of coming up with an original alphabet design fired my imagination. And learning that it was possible to design type professionally was a revelation.” [marksimonson.com]

How the Turner Twins Are Mythbusting Modern Gear Modern adventure apparel should outperform heritage gear, right? Well, the genetically identical Turner twins put this theory to the test...

Twin adventurers are cleverly testing modern vs. historic gear. “If they went on an expedition, and Ross wore modern kit while Hugo wore historic replicas, any difference in performance…could be attributed solely to the gear, not genetics.” [carryology.com]

Book cover of "Designing Data-Intensive Applications, 2nd edition". It has a similar wild boar on the cover as the first edition, but it uses O'Reilly's new cover design, and the boar is now slightly colourised.

The second edition of Designing Data-Intensive Applications, by myself and @chris.blue, is finished and sent off to the printers! Ebooks should be available in the next week, and print books in 3–4 weeks. Sigh of relief. 😅

Inferring Input Grammars from Code with Symbolic Parsing | ACM Transactions on Software Engineering and Methodology Generating effective test inputs for a software system requires that these inputs be valid, as they will otherwise be rejected without reaching actual functionality. In the absence of a specification ...

Fuzzing software becomes much more effective if you can generate _valid_ inputs. We have now built the first approach to _statically_ extract complete and precise input grammars from parser code, producing syntactically valid and diverse inputs by construction. Enjoy! dl.acm.org/doi/10.1145/...

A die photo of the 8086 microprocessor. The image shows a tan square with complex patterns of beige and dark lines showing the circuitry. Thicker light lines distribute power across the chip while black bond wires are attached around the edges. Various regions with different patterns are labeled with their function including a large rectangular region in the lower right that holds the microcode and the 16-bit ALU in the lower left. The ALU Control circuit at the bottom is highlighted.

The arithmetic/logic unit (ALU) in the Intel 8086 processor (1978) is more complicated than you might expect, performing 28 different operations from addition and logical AND to shifts and BCD adjustment. A special control circuit reconfigures the ALU for each operation. Let's look closer...

No? Nuke privacy for everyone in society instead? I see. You clearly had no other choice.

A photo of the 8087 die under a microscope. The die is rectangular, with complex patterns in purplish-brown. The patterns consist of rectangular regions, striped regions in the bottom half of the chip, and other more irregular regions.

At the right, two regions are highlighted in red: the registers and the stack control circuitry.

Around the edges of the die, you can see the hair-thin bond wires that connect the chip to its 40 external pins. The complex patterns on the die are formed by its metal wiring, as well as the polysilicon and silicon underneath. The bottom half of the chip is the "datapath", the circuitry that performs calculations on 80-bit floating point values. At the left of the datapath, a constant ROM holds important constants such as π. At the right are the eight registers that form the stack, along with the stack control circuitry. The chip's instructions are defined by the large rectangular microcode ROM in the middle.

In 1980, Intel announced the 8087 Math Coprocessor, a chip that made floating-point 100 times faster. I opened up the chip, took photos of the silicon structures, and analyzed its circuitry. It's a very complex chip for its time. Let's take a look inside...

By carefully slicing C++, engineers created one of the strictest coding standards ever written.

The world’s first microprocessor is *NOT* from Intel.



But you won’t find it in many textbooks.



It was a secret only declassified in 1998; for good reason. 



The Garrett AiResearch F14 Air Data Computer was 8x faster than the Intel 4004, and a year earlier!

Possibly a carpenter bee, feasting on a drop of honey placed on a small tree branch, over grass.

Brought up some honey to a (possibly) carpenter bee, that looked pretty exhausted. Quite uncommon for me to find them on the ground; lots of woodpeckers and other predators visit the garden.

Hope it can fuel up quickly and return to its nesting log soon enough!

Frank Klepacki, particularly Command & Conquer (1995). It was an "AWE32" moment where a great game could have a soundtrack as good as the game/gameplay itself. In my opinion, Klepacki's soundtrack was on a different level, becaming an instant favourite for many years (decades!) to come.

Colleges do a terrible job of teaching C++.



It’s not “C with Classes”. Injected into curriculums as a demonstration of early CS concepts, it leaves many with a sour taste.



Students later immediately fall in love with the first language that *doesn’t* feel that way.
