Off in the wiki, there is a "How To Add An Instruction" page which gives a good idea of the scope of the project. It includes extending the instruction set, chip logic, assembler, compiler, and simulator along with tests for each

Older enough programmers will remember the DEC Vax to Alpha binary translators. When DEC produced the Alpha you could take existing Vax binaries, run them through a tool, and have a shiny new Alpha binary ready to go.¹ Given such a tool, wh

The basic setup is a stake on a turntable in the path of an X-ray beam. There is a blower from above to simulate moving through air. Also included are a stereo pair of high speed cameras. The hapless fly is glued to the stake and rotated wh

If you have an engineer using publicly broadcast random numbers in your cryptography, the problem did not originate in the font size of the "Beware of the Leopard" sign.

Looks interesting. I would have chosen this for a couple of past projects. $45, but you get a display for that. Even if you think you can communicate enough information with a few LEDs by the time you think about assembly time, packaging, a

Very nice. I just ran a half dozen varying songs which we perform through it and it mostly matches my chord sheets. For some bands this will be a dynamic changer. Singers who can not write down chords sometimes don't want to impose on

First, the headline number comes from 64 25gbps fibers in parallel. I found more interesting this little bit buried in the bottom quarter of the article… Intel is proposing an Optical PCI-Express (OPCI) protocol for use on optical wires.

I don't know how they plan to handle it. In a similar game I've worked on (unpublished) gravity is handled like our universe, but with a bias toward the three orthogonal axis. This leaves you feeling like a 2d world on the faces,

Just an anecdatum: I used lpsolve, a general linear programming solver, to layout constraint based user interfaces with no perceptible delay to the user in a desktop situation (no network to blame)… in 1996, on an Intel 486dx50 with 16MB of

It sounds reasonable to me. They have provided evidence that the woman has died, and that she left an iPad. Apple is asking for a legal declaration that it is this iPad and this iTunes account. "We've provided the death certifica

Precisely. I remember when the track names for some of my CDs vanished because CDDB had taken the data I created for for them private and I was no longer able to see the information I typed in.

At the link level, your MAC is your unique address. First: You do not want a MAC collision. I have worked with hardware that sometimes picked a non-unique MAC and your life gets really weird and sucks away a lot of debugging time to find

Gasometers have largely passed as a result of high pressure distribution systems. Ours are disused or removed in St. Louis. Wikipedia explains that they are rare in the U.S. and those were some of the only ones. The UK gasometers are largel

A language with everything would be a nightmare. To program efficiently you need a balance between capability and mental footprint. If I have to write large amounts of code to accomplish a task, that is bad for me and the eventual reader. I

I'm with you here. Golang has a lot going for it, and it isn't shy about its shortcomings, but the story is "Try it, you'll like it." After a year, I still find myself bogging down coding things which should be easy

emacs and some of the TeX programs worked that way. Maybe they still do. I haven't looked at that in a quarter century. To elaborate: the programs would do all of their initialization and loading of things that would be used in any run

In the Mavericks version there are two jumps to labels that are not present in the code shown. One is for tagged pointers, the other is for a cache miss. The cache miss is probably interesting, tricky code. Apropos nothing… the cache search

I wonder how "sturdiness" scales. What happens when you drop or bang a battery with such tiny features? Obviously they are very weak, but they also have very little mass. I generally count on HN to have someone with experience in

If you think you want to do this in the future, then get your corporate D-U-N-S number and corporate Apple developer account. Things can go wrong in this process, there are horror stories of it taking many weeks.
