Shadowing at AST level with the lexical scope is easy to implement, it's just each usage looks up inside out to parent scopes. But if we treat each assignment as a kind of shadowing, it works in a similar way and turns into a kind of S

Yes, a lexical scope with shadowing

My idea was that with single pass, I can build SSA form during AST construction, and use phi-nodes to update type flow info. Then I could use SSA form to prove that I can use certain optimized bytecode instructions when a variable/regi

A genuine question: is the first point (flow typing / type narrowing) a subset of or intersection with or just an alias to SSA (static single assignment)? I'm playing with a small interpreted language implementation that is based

At least Options+ application works. I tried this one in June with my M720, which I like a lot, and it could not even detect it. Alpha quality at best. As another comment mentioned, the air-gapped download for Options+ is fine. Yes, Options

This is something I'm ready to pay for. Not more per token, but I will be happy to burn through 20x Pro subscription as fast as I consume my Plus weekly limit now, with 10x more tokens per unit of time. I've learned how to deal wi

It's funny that I said "evacuate" and did not mention air travel. In that part of the world, trains are the default, with nuclear green power powering the majority of consumers. Maybe that other default is a problem. And yes,

I've seen dozens of videos and articles about this strongest ever event. And I still have no clue if the next year I should evacuate from Paris for the summer because heatwaves may be even crazier than this year, or prolonged heavy rai

I had plans to buy two Airs, was not sure if I needed 13 or 15, 24 or 32, which was better for my wife and what's the best strategy to buy one for her first and then understand my needs test-driving it. Maybe I actually needed Pro. Lot

In the context of a proxy one should mention epoll_wait busy poll. I've recently dived into this when reviewing low-latency options, and found that it's almost possible to do user space busy polling just for simple sockets, no DPD

Picollo is a new library for serious performance work in .NET. Picollo stands for Performance Instrumentation and Continuous Observation for Low-Level Optimization. The initial public release of Picollo v0.1.0 contains two components. First

No, it should be a required (by law) opt-in TRACK_ME_I_DO_NOT_CARE_OR_AM_A_TEAPOT=418. The proposed way just normalizes tracking.

TrueNAS works perfectly as a VM eg on Proxmox with passing through a SATA controller from the motherboard. It may not work always with bad IOMMU groups, but I have this on an old Xeon Precision Tower 3420 and not so old Asus Z690 motherboar

For some time recently, I was zooming in on Bosch's The Garden of Earthly Delights. The floor's level of interactivity would be so nice there. At least on this floor, I can guess what's going on quite reliably. The experience

Group Policy Edit is the way to restrict many things. Disabling automatic updates helps. I have had forced reboots very rarely, I believe that were severe vulnerability fixes. But my use case is never 24/7, I hibernate it overnight and

Agreed. I had to run Windows recovery only once over the last 5+ years, after running some debloating script with many thousands stars on GitHub. I think the Pro version is enough for reasonable experience, most of the terrible stories orig

Then at a lower level and smaller latencies it's often interrupt moderation that must be disabled. Conceptually similar idea to the Nagle algo - coalesce overheads by waiting, but on the receiving end in hardware.

I could do half-screen nested array formulas when Excel was before the ribbon (and screen resolutions were smaller), out of necessity and because I could. It was in quite demanding uni home calculations and then mostly when working as inter

Unsafety means different things. In C#, SIMD is possible via `ref`s, which maintains GC safety (no GC holes), but removes bounds safety (array length check). The API is called appropriately Vector.Load Unsafe

It looks suspicious at 25x. Even 2.5x would be suspicious unless reading very small records. I assume both cases have the file cached in RAM already fully, with a tiny size of 100MB. But the file read based version actually copies the data

Microsoft is notoriously bad with naming. In this case likely intentionally. The SKUs: Home = Crap, Pro = OKish Windows, Enterprise = Pro. But people who do not care about lack of RDP server, Hyper-V, BitLocker do not care about the rest, p

I wonder if most complaints are about pre-installed OEM Windows Home (the one with Candy Crush and 10s of other crap, including from a vendor) and bundled crappy cut-off OneDrive? I have Windows Pro and Office 365 Family option (5 accounts,
